There's a lot of problems with the 5.0.1. I have Bluetooth problems, battery problems. and several others. I had a Note 4 with Verizon before I went to Sprint where I also had a Note 4 and now I'm back with Verizon with the Note 4 again. I know it's not the phone or how i use it since i don't leave location on or other battery draining settings.
Republic wireless knew about the problems with lollipop and went straight to Android 6.1...
