How to use Samsung Gear S2 / Gear S3 / Gear Sport with devices that have less than 1.5GB of RAM

Issue

When you try connecting your Samsung Gear S2, Gear S3 or Gear Sport smartwatch to
a smartphone that has less than 1.5GB of RAM for the first time, you are in for a nasty surprise; although you can find and install Samsung Gear manager application from Google Play store onto your device, it will be unable to successfully connect your smartphone and the Gear S2 / Gear S3 / Gear Sport.

If you try to connect Gear S2 / Gear S3 / Gear Sport to your device manually, that is directly from phone’s bluetooth settings, the phone is able to find Gear S2 / Gear S3 / Gear Sport and even initiates the pairing process together with the “Confirm passkey xxxxxx to pair with Gear S2.” or “Confirm passkey xxxxxx to pair with Gear S3.” message. After you confirm the bluetooth pairing request, a “setting up…” text is displayed on your Gear S2 / Gear S3 / Gear Sport watch but the process doesn’t succeed. The connecting process between the smartphone and Gear S2 / Gear S3 / Gear Sport needs to be performed from within the Samsung Gear app in order to be successfully completed.

The reason why Samsung Gear app is unable to find and pair the Gear S2 / Gear S3 / Gear Sport with devices that have less than 1.5GB of RAM is the Samsung Gear manager app itself; the developers at Samsung enforced a minimum RAM requirement check into the app. When Samsung Gear app is run on the devices that have less than 1.5GB of RAM, it is only able to find and pair with Samsung accessories such as Gear Triathlon S/M, Gear IconX R/L and Gear Circle but not the Gear S2 / Gear S3 / Gear Sport.

I suspect the reason for their decision is they have encountered some performance issues on some of less capable smartphones during the testing phase and decided to drop support for the mentioned devices altogether to prevent potential complaints from customers.

Solution

I was able to disable the minimum RAM requirement check from the Samsung Gear app and thus make it work on whole range of Android smartphones that have less than 1.5GB of RAM. This was accomplished by decompiling the Samsung Gear apk, modifying the rules.xml file (adding hostMinMemory=”0″ syntax), recompiling and re-signing it.

Beside the Samsung Gear app, Gear S2 / Gear S3 / Gear Sport also requires two additional apps to be installed on the smartphone in order to connect and function as intended; Samsung Accessory Service and Gear S plugin. These apps also had to be re-signed, since they wouldn’t install successfully if downloaded directly from Google Play Store, when there is a re-signed Samsung Gear app installed on the system.

I would like to point out that the integrity of the Samsung Gear app wasn’t compromised in any way since I didn’t do any other changes, beside disabling the minimum RAM requirement check before it initiates the pairing process.
Modified app works the same as the one downloaded from the Google Play store.

Compatible devices

The modified Samsung Gear app should work on a whole range of Android smartphones (Android 4.4 Kitkat, 5.x Lollipop, 6.x Marshmallow, 7.x Nougat). Please note that synchronization with Samsung Health / S-Health app will not work with modified Samsung Gear app (click here for more information). For Samsung phones ROOT is required.

If you have a Samsung phone and are getting “The operating system on your phone has been modified in an unauthorized way, and is not compatible with the Samsung Gear app. Check your operating system and try again.” error click here.

Below is the list of devices that are known to be working with the modified Samsung Gear app and Samsung Gear S2 / Gear S3 / Gear Sport smartwatch:

  • ALCATEL Pixi Unite A466BG (Android 6.0, 1GB of RAM)
  • LG G2 mini (Android 4.4.2, 1GB RAM)
  • LG G3 (Android 6.0, 2GB / 3GB RAM)
  • LG Ultimate 2 L41C (Android 4.4, 1GB RAM)
  • LG Zone X180G (Android 5.1, 1GB RAM)
  • HTC One Mini (Android 4.4.2, 1GB RAM)
  • HTC One Mini 2 (Android 4.4.2, 1GB RAM)
  • HTC Desire 626G+ dual sim (Android 4.4.2, 1GB RAM)
  • Motorola Moto G (1st Generation) (Android 4.4.4, 1GB RAM)
  • Motorola Moto G3 (Android 5.1.1/6.0, version with 1GB of RAM)
  • Motorola Moto g5 Plus (Android 7.0, 2GB of RAM)
  • Motorola Moto E (Android 5.1, 1GB of RAM)
  • Motorola Photon Q 4G LTE XT897 (Lineage OS Marshmallow, 1GB of RAM)
  • BQ Aquaris A4.5 (Android 6.0, 1GB of RAM)
  • *The list will expand as more compatible devices are reported by users.

*Synchronization with Samsung Health / S-Health app doesn’t work
Workout and lifestyle data from the Gear S2 / Gear S3 / Gear Sport doesn’t show in Samsung Health app on the smartphone. Reason for this is that Samsung Health app checks signature of Gear S Plugin and refuses to sync or exchange data with it, because it wasn’t signed by Samsung. On non-rooted phones only workaround is to use other exercise tracking apps such as Endomondo, MapMyRun or Under Armour Record for Gear S2 / Gear S3 / Gear Sport. Mentioned apps are currently only able to transfer limited exercise data from Gear S2 / Gear S3 / Gear Sport to Samsung Health app, such as workout start/stop time, distance, sport type and calories.
On rooted phones there is a possibility to install an un-modified Samsung Gear, Gear S Plugin, Samsung Accessory Service and Samsung Health from Play Store (Or Galaxy apps store on Samsung phones), starting the Gear app, rebooting the phone and then going to \data\data\com.samsung.android.app.watchmanager\files\ directory with File manager that has root access (in ES File Explorer go to Settings, Tools and turn on “Root Explorer”) and manually editing (adding hostMinMemory=”0″ syntax) rules.xml file (Open it with Es Notes Editor). By using original apps signed by Samsung, sync with Samsung Health works as intended. Do not forget to turn off Auto update for Samsung Gear app afterwards, otherwise it will overwrite rules.xml file with an original version on every app update.

Connecting to Samsung Gear S2 / Gear S3 / Gear Sport

Please follow the steps below carefully and in the exact order to successfully connect the Gear S2 / Gear S3 / Gear Sport to your smartphone. Do not attempt to skip any step.

1. Remove existing Samsung apps

If you have installed Samsung Gear app from Google Play Store you will need to remove it in order to install modified Gear app. Go to Settings -> Application Manager / Apps -> All and search for Samsung Gear, Gear S Plugin and Samsung Accessory Service. If any of the mentioned apps is found, it needs to be removed / uninstalled. Restart your smartphone after the uninstall.

2. Unpair Gear S2 / Gear S3 / Gear Sport

Go to Settings -> Bluetooth and look under the Paired Devices. If Gear S2 / Gear S3 / Gear Sport is listed under the Paired Devices, you will need to un-pair it.

3. Allow installation of apps from unknown sources

Go to Settings -> Security and make sure that there is a check-mark next to “Unknown sources”. This will allow installation of modified Samsung Gear app.

4. Download the modified Samsung Gear app

Click on the link below to download the modified Samsung Gear app, re-signed Gear S Plugin and re-signed Samsung Accessory Service. All three apps are packed in a compressed .zip package. Download the .zip file to your computer, unzip or extract it and then transfer apps (.apk files) to your smartphone. In case you don’t have access to a computer, you can download .zip file directly from the browser on your smartphone and then use File manager to extract apps.

5. Install apps to your smartphone

Use a File manager app to browse for the transferred apps (if you downloaded .zip file directly from smartphone, it should reside in the “Download” folder in internal memory or SD card). Tap on each of the three apps to install it. Accept all required permissions during installation.

6. Preparing Samsung Gear S2 / Gear S3 / Gear Sport for connection

Restart your smartphone and make sure Bluetooth is turned on before attempting the connection. Make sure your Gear S2 / Gear S3 / Gear Sport is turned on and in “discovery mode”, the text “Install Samsung Gear on your phone.” should be displayed, as seen on the picture below. If something else is displayed on screen of your Gear S2 / Gear S3 / Gear Sport, you will need to reset it, by pressing “Home button”, tapping on the “Settings” icon -> Gear info -> Reset Gear. Or in case when Gear S2 / Gear S3 / Gear Sport was connected to another smartphone, by pressing “Home button”, tapping on the “Settings” icon -> Connect to new phone.

7. Connecting Samsung Gear S2 / Gear S3 / Gear Sport using modified Gear app

Open the installed Samsung Gear app, tap on the “Connect to Gear” button and wait a bit for the phone to find the Gear S2 / Gear S3 / Gear Sport. If it doesn’t find it the first time, repeat the step. After the Gear S2 / Gear S3 / Gear Sport is found, tap on the “Gear S2” / “Gear S3 / Gear Sport” text, wait for the Bluetooth pairing request and confirm the pair. Also make sure that you allow or confirm any further permission requests. If all went well, your Gear S2 / Gear S3 / Gear Sport should now be successfully connected to your smartphone.

8. Provide feedback to help the community

If you would like to help other fellow Gear S2 / Gear S3 / Gear Sport owners who are unable to connect it to their smartphone, please provide some feedback (model of your smartphone, version of Android, possible issues) in the comments below or via email to info@getgui.com. If the modified Samsung Gear app works on your smartphone, it will be added to the list of compatible devices, otherwise we will try to find a solution together.

  1. Moto E (tracfone cheapie but still nice phone) with 1GB RAM worked just fine … so far.

    Thanks for this.

  2. Hi,
    Thank You for Your work, but after instalation, when I try open app, I get an information that my system has been changed by unauthorized way and application won’t be opened. My phone is samsung galaxy s3 mini, and stock is not available in version 4.4 of android. I flashed it with custom rom 4.4.4. Do you know how to bypass it? Maybe there is some option that checks flash counter or phone code with available official OS version? I dunno…
    I really, would like to help You add another compatible phone to the list 😉
    Thank you!
    Cheers

    1. Hello,

      there is an issue when using modified apps from my blog on Samsung phones because the apps are not signed by Samsung.

      On rooted phones you can get around this issue by modifying build.prop file like described below:

      Try editing your build.prop file with ES File Explorer or similar program – search for build.prop file with ES File Explorer and when you find it, tap on it and select to open it with ES Note Editor. You then need to replace all entries in the build.prop that say samsung, to htc for example. Entries are case-sensitive. After you modify the file, try exiting the ES Note Editor and choose to save changes in the save changes dialog window. Open the file again and check if the changes are there, if they aren’t, it is because ES File Explorer doesn’t have root privileges – make sure to put a check mark beside the “root privilege” in the settings of ES File Explorer. Please note that changing the build.prop file could lead to some issues – mainly that you couldn’t find some Samsung specific apps on Play Store because your phone is identified as HTC. Reboot phone after making the changes to build.prop file. Please report back the results.

        1. Hi,

          modified apps don’t work on Samsung phones, the only way to make it work is to root the phone and modify the build.prop file or install original apps from Galaxy Store and then manually editing the rules.xml file directly on the phone. This also requires root. Both procedures are described in the blog post.

      1. Hi. my phone is galaxy grand 2. I did everything you said but it’s not connecting to my gear s2.. i changed in build prop all samsungs to htc.. but it says that the operating system is modified

        1. Hello,

          Try changing the values in the build.prop, then restarting the phone and when you open the build.prop file again, the changes should be there. If they are not it means the file was not properly saved or there is an issue with root.

    1. These apps are not designed to work with Gear 2 Neo, they are for Gear S2 and Gear S3.
      Your phone has 2 GB of RAM so it should work with original, un-modified apps from Play Store.
      If it doesn’t work, try XDA developers forum, maybe someone is experiencing the same issues.

  3. I have a moto e and the samsung gear properly installed but when i try to open the gear s2 plugin app i cant, can anyone help

  4. Thank you!

    I cannot praise Simon enough. I tried Samsung for help, but they were no use. Simon however enabled me to use my Motorola Moto G3 with my new Samsung Gear S3 watch perfectly. He responded immediately to my question and his help was invaluable.

    1. Andrew thank you for this comment, I’m really glad we had sorted out the installation issue.

  5. My phone is not rooted still it shows my system has been changed by unauthorized way an application won’t be opened. I’m using Galaxy Grand Prime.

    1. Hello Ayush,

      for Samsung phones the build.prop file needs to be adjusted as per instructions in the blog, to be able to do this, the phone needs to be rooted.

  6. I can’t install the app with the link given above. When i tried to open the downloaded one. It says this file format is not supported

  7. Hello, in my case i get an alert that says “The OS has been modified with an unauthorised way and is not compatible with the app samsung gear. Please check the OS and try later”
    Any suggestions??

    1. Hello,

      for Samsung phones the build.prop file needs to be modified as per instructions in the blog post.
      To be able to do this, the phone needs to be rooted.

  8. I have a Samsung J1 Mini (1gb RAM), rooted. I’ve edited the build.prop as directed to htc and have confirmed the changes remained on reboot, and installed the modified apks. Sadly I still cannot see my gear s in the Samsung gear app; is there anything I can do to make it work? Thanks!

    1. Hello Nathan,

      the modified apks from the blog post are meant for Gear S2 and S3, they will not work with Gear S.

      I have made another modification to the Samsung Gear app in hope to enable support for Gear S.

      You can try the modified apks by downloading them from the link below. Remember to remove the previous versions of Samsung Gear, Gear Plugin and Samsung Accessory Service before installing.

      https://www.dropbox.com/s/nvnjcirkxgzm7qo/Samsung-Gear-S-Test-GetGui.zip?dl=1

      Please report back.

      1. Hey mate,
        Cheers for putting this together so quickly, I appreciate it. Starts off promisingly; gear s appears but when I click to connect I get a pop up saying “Tap OK to install com.samsung.android.gear2smodule to enable the data transfer between your Gear and your phone.” When I click OK I get sent to the play store but get an Item not found error. I uninstalled all 3 apps and installed the modified ones you posted as directed. And again, thanks heaps for your help!

  9. Hello again,
    The fix you’ve uploaded isn’t working; this time the Gear app crashes after I select my watch (where I previously got the popup).

    1. Hello,

      the only thing I can think off now, is that Gear app requires both mentioned apks (com.samsung.android.gear2plugin and com.samsung.android.gear2smodule) in order to function.
      It is a bit hard to develop a solution, since I don’t have the Gear S watch and I’m testing modifications only in an Android emulator…which means I can only test the installation process.

      Try to download the .zip package with all four apks, from the link below:

      https://www.dropbox.com/s/99fxnu8ba782c30/Test3-Samsung-Gear-S-GetGui.zip?dl=1

      If this will not work for you, the only other way I can think off is to download un-modified Samsung Gear app from the PlayStore and manually modify the rules.xml file afterwards (instructions are in the blog post). This procedure doesn’t require the Gear apps’ signature to be modified, which means the Gear app should be able to download the required packages from the Play Store. At least in theory that is.

      1. Hello,
        I’ve installed all 4 APKs, and now I get to the Connecting to Gear… page; but it stays on that page indefinitely. I’m going to try modifying the rules.xml; but I can’t download the Samsung Gear app in the Play Store. Would the process work if I used an unmodified APK downloaded from another website, provided they haven’t changed the signature? Or would I have to edit the build.prop again, but to a model of phone that’s listed as compatible with the Samsung Gear app?

        I really appreciate everything you’re doing to help- you’ve gone above and beyond what I expected!

      2. Hello,
        I’ve installed all 4 APKs, and now I get to the Connecting to Gear… page; but it stays on that page indefinitely. I’m going to try modifying the rules.xml; but I can’t download the Samsung Gear app in the Play Store. Would the process work if I used an unmodified APK downloaded from another website?

        From what I can gather, all I have to do is add the line hostMinMemory=”0″, correct? Would I need to change anything to make it work on the Gear S (as the post is for the s2 and s3) or is that all I need to do?

        I really appreciate everything you’re doing to help- you’ve gone above and beyond what I expected!

        1. Hello,

          it would be best if you could modify the build.prop file to match one of the phone models that are on the Gear S supported list –
          change all htc entries back to samsung and also try one of these: ro.product.model = GT-I9500 or ro.product.model = GT-I9300.
          After rebooting your phone, you should be able to download the Gear app from the Galaxy Apps store (Not the Playstore), but be sure to remove all the modified or Gear related apps in advance.
          Then you have to add the hostMinMemory=”0″ to the rules.xml, same as on the picture below.
          Modifying rules.xml file to bypass minimum RAM requirement for Samsung Gear
          Then the Gear app should be able to download the required apps automatically, during the connecting process.

          But please make sure to do a complete phone backup before attempting any modifications to the build.prop file. If something goes wrong, your phone could be stuck in a bootloop. In that case phone can be rescued by flashing the official firmware, but all the user data on the phone could be lost.

          1. Thank you so much! That did it, it’s working great!

            For anyone reading this in the future who has a Gear S and the Samsung J1 Mini (might work for other Samsungs too), this is the process:
            Step 1. Root your phone if it isn’t already, and do a complete phone backup
            2. Edit the build.prop line “ro.product.model” to ro.product.model = GT-I9500 and reboot
            2.a. If you get stuck in a bootloop (I didn’t, but it’s possible) flash the official firmware onto the phone (there’s tutorials online as to how to do that)
            3. Download the Samsung Gear app from the Galaxy Apps Store (NOT the Play Store)
            4. Run it once, but close it without clicking anything (this generates the files needed in step 5
            5. Go to \data\data\com.samsung.android.app.watchmanager\files\ and edit the rules.xml as it says in the above reply from Simon
            6. Open the Samsung Gear app, follow the instructions onscreen!

          2. Hello Nathan,

            you are welcome, I’m really glad that we have solved this issue.

            And thank you for posting the detailed instructions, they will certainly come handy for other users who are facing similar problem.

  10. Hi
    Do you know if the gear s2 and s3 work with a Sony Xperia E4
    Android version 4.4.4 and 1GB of RAM

    1. I also can’t access the link from an iPad it just says untitled and loads forever and I’m not sure if it is the same thing with my phone

    2. Hello,

      I don’t know for sure but I believe it should work by using modified apps from this blog post.

      1. thanks but the direct link does not work for some reason, it just keeps saying download failed

  11. I can’t pair my Lenovo TB3-710l with S3. The app works, turn on bluetooth but did’t show any devices. Pity.

    1. Hello,

      unfortunately the Samsung Gear app doesn’t allow tablets to be used, only phones.

  12. Great work!
    I tried these apps to connect Samsung Gear Sport and CAT S40.
    Apps work and seems to connect the devices with each other, i.e. there is connection between devices initially. Both devices show passwords etc and app show paired device but then the watch says “Check your phone to complete setup” and after that “Connection failed. Try again.” When trying to connect again it repeats the fail message.

    I tried many times but with no luck. Is your modification suitable for Samsung Gear Sport as well as it uses the same apps? Or is it possible to modify so.

    1. Hello,

      the modified Gear app should work with your Gear Sport watch, since the minimum RAM restriction has also been removed for the Gear Sport (in the rules.xml file).
      It also uses the same Gear plugin as Gear S2/S3, which is included in the package.

      Are you running a stock or custom ROM on your phone? Is your phone rooted?
      Are you running the latest firmware on the Gear Sport watch?

      1. SUCCESS!
        Thank you very much for the info provided!
        Samsung Gear Sport watch and CAT S40 successfully paired.
        Maybe I did something wrong but I couldn’t connect with the APP files provided above. It somehow connected and then failed.
        Anyway I followed your steps for modification, i.e I downloaded the latest APK-s for the three apps. De-compiled those, modified rules.xml file, compiled again and installed those to the phone according to your instructions. It connected and also the phone app connection interface was different from previous try. So I think the software versions from watch and Phone didn’t like each other.
        I didn’t believe that I succeed as I am not IT specialist but it worked out great with some googling.

        Thank a lot!
        Gotham

        1. Hey,

          that is great news, I’m very glad that you have managed to make it work!

          I would be very grateful if you could report the versions of the installed Gear app, Accessory Service and Gear plugin that work for you. I would like to offer these on the blog for other users that are facing similar connectivity problems.

          Best Regards,
          Simon

        2. Great could you please upload the files in Dropbox or anywhere else?

          I hava the same device and Problem

          THX in advance

          1. Hi,

            Gotham has kindly provided me with the versions of the Samsung Accessory Service and Gear S Plugin that work for him.

            I will re-sign the apps and upload them to Dropbox in the next hour.

          2. Hello,

            I have uploaded the new version (20. December 2017) to Dropbox, the link is in the blog post.

            This should work with Samsung Gear S2, S3 and Gear Sport.

  13. thank you very much my friend, followed your steps and got it working on my samsung A3 2015 (1gb ram)

  14. Hi Simon,

    thanks a whole lot for this, App was not downloadable from Play store for my Moto XT 1032, Android 5.1. Your apps worked fine. Saved Christmas 😉

    Thanks a lot
    Achim

  15. Hey Simon,
    Thanks for this. I confirm it works with HTC one mini (1Gb of RAM).
    Just got the S2 watch today and of course nothing worked 🙂
    This saved my day and I don’t need to sell my watch or get a new phone! Ah crazy technology world.
    Greetings from France

    1. Ross you are welcome.

      Thank you for your feedback, your device will be added to the compatibility list.

      1. I should clarify that I am using it with a Samsung gear fit 2 pro using the modified APK. Everything works as expected. Syncing with Samsung health does not work, which is also expected.

        I would like to try the unmodified apps but the play store will not let me install them after uninstalling. Is there a trusted source to download them?

        1. Robert for Samsung Gear Fit2 you will need these apps – Samsung Gear, Samsung Accessory Service and Gear Fit2 Plugin.

          You can download unmodified apps (look for latest versions) from http://www.apkmirror.com

          If you are concerned about the safety of the downloaded apps, you can check their signature by uploading them to this site – https://apkpure.com/apk-signature-verification

          If apps were modified in any way they will not pass the above signature check because after modification they are no longer signed by Samsung.

          And I see no reason why original, unmodified apps wouldn’t work on your phone, since it has 2 GB of RAM if I’m correct.

  16. Unfortunately Gear App isn’t visible in Play Store on my 2017 Samsung Galaxy SM-J700M even though it has 1.5 GB of RAM.

    I installed your modified version and it doesn’t open because I am unable to root this phone. I have tried all available Android and Windows based rooting tools without success

    Thanks anyway for posting

    John

    1. Hello John,
      please search for Gear app in the Samsung Galaxy store instead.

      And if you are unable to find it there, please contact me and I will provide you with the unmodified apps.

      Best Regards,
      Simon

    1. Marco you are welcome and thank you for your feedback. Your device will be added to the list.

      Best Regards,
      Simon

    1. Ricardo you are welcome and thank you for your feedback, your phone has been added to the compatibility list.

  17. I installed everything and it works great except Samsung Pay. I had to download Pay after i downloaded the modified files from you. I am being daft? How do i get pay to work?

      1. Hello,

        I’m sorry for a late reply, I was on vacation. I’m glad to hear you have fixed the issue in the meantime.

        You can update the firmware on the watch, but do not update the Gear app – You can find the latest version of the modified Gear app on this blog.

    1. Can you please be more specific – what kind of error message do you get, which watch are you trying to connect?

      1. No message it just never fully pairs like it was doing before using the actual play store application. Trying to connect a Gear S2.

        1. Have you uninstalled all the original Samsung apps (Gear app, Samsung Gear Plugin, Samsung Accessory service) before installing all three modified apps from the package? Watch needs to be removed from the Bluetooth paired devices before connecting it for the first time, via the Gear app. Also the watch needs to be in the pairing mode.

          https://www.samsung.com/us/support/answer/ANS00046104/

  18. Hi Simon, I have nearly the same problem, as GOTHAM. I use official Gear App on ZOPO 952 (3GB RAM) and Gear Sport watches. I see the Sport in GEar app, the pairing does well but after it i see the message that “Connection failed. Try again.” Clould you please place here the files that help GOTHAM? Or any other sugestions?
    Thanks

    1. Hello,

      Gotham downloaded original apps from PlayStore and then manually edited the rules.xml file (on the phone) after the apps were installed. This procedure is described in the blog post.
      The mentioned procedure requires a rooted phone, else the rules.xml file could not be edited.

      It could be that the current version of the modified apps available on the blog is not compatible with the firmware on your watch.
      I will try to modify and upload the newest app versions later today.

      Best Regards,
      Simon

    1. Hello,

      I have uploaded the newest modified files to the blog – Gear app and Samsung Accessory service are the same version as from the previous package (newer versions were not released in the meantime by Samsung) and the newer version of the Gear Plugin is included.

      Be sure to uninstall any previous apps from Samsung by going to Apps / App manager (and looking for Samsung Gear, Samsung Accessory Service and Gear Plugin) before installing the new versions.
      Also make sure that you un-pair your watch from the Bluetooth settings on the phone.
      Watch needs to be in the “pairing mode” before initiating the pairing process.

      I hope this will work for you, please let me know.

      Best Regards,

  19. Hello, Simon,
    I tested files from previous post but no success. I finaly solved the problem by buying a new phone (Zopo was still functional but technologically it was already behind its peak). Yet (like everyone in this blog), I greatly appreciate your willingness, helpfulness, and effort to help.

    Thanks
    George

  20. Hi Simon,

    I have a HTC One Mini 2. I’ve followed all the instructions but when I start the installation command after 2 sec the installer stop and error message appear on screen: App not installed.
    That’s true for all 3 .apk files.
    Any idea?
    Thanks a million,
    Zoltan

  21. Hello Simon,

    I have a HTC One Mini 2.
    I’ve followed the steps above but once I tried to install the .apk files the process stop after 2 sec.
    In all three files the same massege pops up: App not installed.
    Any idea what could be the problem?
    Thanks a million!
    Zoltan

    1. Hello Zoltan,

      please check Apps/App manager for all the Samsung software (Gear app, Samsung Accessory Service, Gear Plugin) and uninstall it before installing the modified files.
      Usually the error you are experiencing is caused by having one of the original Samsung apps installed on the phone while installing the modified versions.

      Best Regards,
      Simon

  22. Hi Simon,

    You were 100%. I’ve overlooked one previous app.

    All works perfectly now!

    Many thanks for your immediate support. You made my day!

    Thanks,

  23. Hey can you repost the files for the gear s (the ones you posted for Nathan)…the Dropbox links are dead. Thanks in advance

  24. i have a j1 6 samsung and i rooted it and can open the gear app it finds the watch in the pair when i click the info of the watch it starts pairing the it says gear s plugin has stopped how do i fix this

    1. Hi,

      do you have a stock or custom ROM on your phone? What is the firmware version on the watch?

  25. I have a galaxy grand prime and I understand that I must root my phone, and have tried many things like Kingoroot etc. but I none of them work. Do you have any tips on how I can root my phone in order to do this? Please help asap, thanks!

    1. Hi,

      instant root solutions such as Kingoroot, rarely work.

      Please search XDA forums to get a proper root solution, the two links below might help.

      Before rooting the phone, make sure that the root solution matches the exact model of your phone and make sure to do a backup before hand. Rooting is risky – if something goes wrong (phone is stuck in a boot-loop), you could loose all your data trying to restore it to a working order.

  26. I do not have a PC, and neither of the methods on the website work… I would really love to be able to use a Gear s2 but I still can’t find a way to root my phone. It’s a SM-G530T by the way. Can you please try to find a way to try to for sure work. Thanks so much! 🙂

  27. Yes I know, I am wondering if you could find a way that can definitely work, or any explanations as to why it isn’t working and how I could fix it.

    1. Every Android app needs to be digitally signed with the certificate after it has been created or modified, otherwise the system doesn’t allow installation.

      After I modify these apps I sign them with my own certificate and this works for every other brand of devices, except for Samsung ones. On Samsung phones there is a protection in place, that checks the signature of every app made by Samsung – if it wasn’t signed with the certificate from Samsung, it will not allow it to run, since it knows the app has been modified and is a potential security risk.

      Apart from rooting the phone, you could also try installing a custom pre-rooted ROM.

  28. Can you please explain what a pre rooted ROM is and give a link to one that might work for me?

    Once again thanks soooo much for continuing to communicate with me!
    I would really like to get this to work!

  29. Hiya,

    I can’t seem to get this to work for my Motorola Moto G3 and Samsung Gear S2. I have followed all steps but it still isn’t finding my S2 from the Gear app unfortunately. Is there something I could be missing?

    Cheers,
    Jack

    1. Hello,

      this should work since there are users that confirmed it works with their Motorola Moto G3 phones.

      Please make sure to remove all previous Samsung apps from your phone before installing modified apps from my blog.

      Are you running an official or custom Android ROM on your phone?
