Yeah from what I've noticed today I had 2 data drops compared to at least 10/day before the update...oh and also before the update I was getting at max 2 bars on 4G, this update I'm up to 4 bars. Could be cause most of the towers where I live is updated or could be the build, not too sure on that yet.
It's the build:
"4G coverage indicator accurately displays data connectivity."
