Thanks for that mate…Just an update, installed on my Honor View 10, and it runs flawless…Still no joy on my Oukitel, but I have been testing some settings, and tweaking the battery settings on & off, and I have come to the following conclusion. Oukitel’s interpretation of Android 9 is broken. Or at least the battery tweaking part of it. I’ve found that whether I set power management to ignore apps or not. the system still kills the app sooner or later. I’ve also found that whether I turn “optimizations” on or off, it make absolutely no difference to the apps in question…Very frustrating. The irony of this is that the W6 has a monster 10.000 MAH battery, so I don’t need bloody optimization at all, lol.
