T-Mobile update, notice some people say they are getting 2 different sizes. Mine is 635mb, that is because this phone didn't have 5.1.1 prior to install. I'm assuming those with 5.1.1 already installed will get the 130~mb update.
But here is a screenshot of the update coming through today 6-27-15:
This update has been hitting both T-Mobile S6 and S6 edge since this morning. For people that haven't updated to 5.1.1 and were on 5.0.2 is of 635MB for the rest who updated last month to 5.1.1 is about 128MB or something like that.
No major changes or even a new feature (For people already on 5.1.1) but some are saying that the Memory leak has been fixed or at least it's better and some other say that is to fix the Wifi calling and VoLTE drain bug, anyways, if it is to fixed any of the above, it will be greatly welcome from everybody.
Just updated mine before I went ot work last night. My Edge would usually be around 60-70% idle by the time work is over and that's around 9 hours for work and travel. I just got home and it was at 84%.
