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

Issue

When you try to connect your Samsung Gear S2 or Gear S3 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.

If you try to connect Gear S2 / Gear S3 to your device manually, that is directly from phone’s bluetooth settings, the phone is able to find Gear S2 / Gear S3 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 watch but the process doesn’t succeed. The connecting process between the smartphone and Gear S2 / Gear S3 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 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.

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.

How to use Samsung Gear Fit 2 with devices that have less than 1.5GB of RAM

Issue

When you try to connect your Samsung Gear Fit 2 sports band 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 Fit 2.

Why did developers at Samsung impose such a limit is beyond my knowledge, since I am able to successfully connect and use Gear Fit 2 with Sony Xperia T3 smartphone (Android 4.4.4, 1GB RAM) by utilising a modified Samsung Gear app (I have removed the minimum RAM requirement check from the app). I have contacted Samsung on this matter, but up until this moment, I am still waiting for a more technical response, in comparison to the generic one I received, that can be seen below:
“…In order to proper functionality the Gear Fit 2 with all the purpose it was manufactured for, there are some set of requirement standards set for any phone/ Gear watch. For efficient performance the phone needs particular requirements…”

GPS Dropping Losing Signal Issues with Sport Tracking Apps like Endomondo on Android Lollipop and Marshmallow

Go straight to the workaround

Issue

Endomondo or similar Sport tracker applications randomly losing – dropping GPS signal during the workout, when used on Android 5.x Lollipop or 6.x Marshmallow with the screen turned off. Sometimes Endomondo app uses all the available RAM and forces the phone to reboot. This happens even if the “app optimization” in battery menu is turned off. Hard reset of the phone or clean install of Endomondo (tried different versions) also didn’t help.

The workaround described below works with Endomondo for Android, but should also work with other fitness tracking apps if adjusted properly. Disclaimer: It has some negative impact on the phones battery life during the workout, since the screen is not turned off.
