I know there's a long running thread for the Gear S2, but I thought I would make an explicit post about the issues that I am currently experiencing (Mods - feel free to merge). I am experiencing two main problems:
1) I cannot get the watch to vibrate on alarm. Other users have stated that if they don't touch the watch after beginning sleep tracking it will work. However, this hasn't worked for me either.
2) After ending sleep tracking from my phone, it will restart itself on the phone until you also manually kill the app on the watch (via recent apps > close all).
Is anyone else still having these issues? I'm happy to help test to resolve these problems if possible!
Also as a side note - The battery life issue has been pretty much resolved for me. I can track a full night of sleep and only use ~30% battery!
