I've got a Playaibox Plus with Android 12 and overall am quite satisfied but 3 problems bother me:
1. When I leave my car for like 15 minutes (car powered down and locked), the box seems to be still running but loses cellular internet. The '4G' icon disappears from the status bar, applications report that internet is unavailable. Turning mobile data off/on doesn't help, the same with enabling/disabling airplane mode. After reboot mobile data work normally. Does anybody have this problem or any advice how to restore internet access without reboot?
2. Somehow notifications are completely disabled. I've got original firmware and when I pull down the notification shade it is always empty. I've read somewhere that this was a deliberate decision of device developers aimed at reducing distractions from notifications. Is there any method to re-enable them?
3. Any way to get rid of the annoying navigation ball that pops up on every screen touch?
Thanks in advance for your help.
UPDATE: for the 3rd problem (Floating Ball) I tried PieSettings tool
but it gave no effect.
UPDATE2: Floating Ball can be hidden by revoking "draw over other apps" permission from ApplePie Ball system app - found this in Telegram channel. Problems with mobile internet and notifications persist even after upgrade to Android 13.
