My review of the latest Android 10 beta 5 (v438)
I installed the latest Android 10 Beta 5 version 438 on my device last night and so far the experience has been smooth and lag free and I haven't noticed any major bugs.
My device passed the SafetyNet test and it shows device is certified in the Google Play Store. I have Widewine L1 (my bootloader is locked and checked previously on Android 9, it was L1).
I took a backup of almost all my data but I left few pictures purposely but they weren't wiped.
Battery backup is good. SOT is also good. Gesture navigation works perfectly.
The only small issue I noticed is that there is a slight treble from the speaker output.
Other than that this build is good to go for stable release.
