My OnePlus 7 was perfectly fine even after updating to latest stable 10 other than the play store bug, I now have even more problems
1. Notifications - I don't get push notifications. Gmail and WhatsApp remain stuck unless I open them. I've disabled battery optimization for them both and have also disabled the deep sleep optimization to no avail. I keep missing calls and messages because I didn't open the app.
2. Poor battery - my battery keeps draining a lot. Just listening to Spotify at work I went through 40% battery in a few hours. I used to get 7-8 hours SoT now it's around 4 hours. I tried looking into apps to get some stats but all have bad latest reviews. I even went through my apps to see if there was something rogue or one that I installed and removed all unwanted apps but still the same.
3. Downloads (including Play store) - playstore won't download files or will stay stuck at 99/100%. The only way to get it to work is to either disable the Google app and reboot or turn off Bluetooth and then reboot. I rely on Bluetooth for my wristband and my earphones so that sucks. Google app is also useful and it doesn't make sense to disable it to get downloads. Even for normal downloads e.g. in gmail, attachments won't download and are at 0% constantly.
Any help around this would be appreciated. I just dropped from 53-51% while writing this thread (took 3-4 minutes).
Anyone else with similar problems or solutions? Thanks.
