Great battery life compared to all previous builds! I'm <3 %/h now (build 25.01.2017) compared to ≥5 %/h before! Almost 2/3 as good as the stock ROM's battery life.
24 h from installing, I didn't have any self-restarts (at least 1 - 3 per day with 04.01.2017), no non-responsive black screens after clock alarms (occasional with 04.01.2017). I have access without crash again to "Battery saver and performance". And great that there is finally an "Extreme power saver" and working power profiles!
Camera and gallery apps behave badly! Both lag and hang up during use. No auto-rotation in gallery when called from within the camera.
Cameras in these builds were quite poor in experience and performance, but here the camera has absolutely no ability to focus, makes awful shots, lags and finally hangs.
Probably the most precious thing I miss about the stock ROM is the camera app. It was great, especially the professional mode.
Call barring settings crash the phone app as in 04.01.2017. Not of any use for me, but since it is a crash, I report it.
Downloads app does not show any files in "Downloads" - where is it looking for downloads if not in /sdcard/Download?
