degen Finally fix for me was clean flash OOS 8,
Oh, I see...so you did not have to install an OxygenOS version based on Android 7.0, like 4.0.3...you started from Oreo.
Mmmm, that is what I did...
The phone came with OP3_O2_open_25 (no idea what it is) but it said Android 8.0.
After the failed install of PA, I flashed OxygenOS 5.0.8, but did not try to reinstall PA since.
You tried both Oreo and Pie. How did the eyestrain go? Differences between the two? Thanks!
@KM @degen What is the battery lifetime? I look at the phone stats and found a miserable 3 hours and something :-(
