Android 10 AOSP Custom ROM:
After the release of Android 10 officially to Pixel devices, Xiaomi and OnePlus are also providing beta builds. Now, the AOSP Custom ROM developers have developed the latest ROM version for the OnePlus 7 Pro devices. We have mentioned some of the working features below.
- Video Playback
- There *might* be some crashes here and there because it’s in a very early stage. Future updates can also break compatibility, so be aware before flashing any of these alpha ROMs.
- This ROM is still using blobs from Android P, so it won’t work if you have flashed the latest OOS 10 builds.
- MTP (USB storage mode) doesn’t work
- If OpenGapps somehow crashes, that’s not a bug of the ROM. I have already introduced dirty hack to make it somewhat work but it can still crash from time to time. (if Google’s SetupWizard crashes on first boot and drops you back to boot logo, just wait until it gets into it again. Finish the setup without choosing anything fancy. You can alternatively choose to remove SetupWizard entirely from Recovery)
- Sensors might not work if you reverted back from OOS 10 to OOS 9 firmware (this is unlikely to be a ROM issue)
- There might be other broken stuff but for me, it seems that I have a mostly usable phone now.
