It appears that the first post-Android 5.1.1 update for the Galaxy S6 and the Galaxy S6 edge isn't just limited to France, earlier today we reported about a 230 MB update for the handsets carrying build number G920FXXU2BOG8. T-Mobile has just rolled out a minor update of its own for the Galaxy S6 and S6 edge which brings various bug fixes and performance improvements.
This is not a major update by any means as it comes in at just under 103 MB, T-Mobile is rolling out the update right now for the Galaxy S6 and S6 edge with build number G920TUVU2COF6 and G925TUVU2COF8 respectively. Official support documents mention bug fixes as well as battery and device improvements for both handsets and a cocktailbar error fix for the Galaxy S6 edge. T-Mobile subscribers will be keeping their fingers crossed for a fix for the recurring battery drain bug with VoLTE enabled, this bug has been present since launch and hopefully the carrier has fixed it in this update.
