My honor 8 lite (Android 7.0) started to do strange stuff:
- While WiFi tethering works, and my PC is connected, the tethering turns off after a few minutes.
- Even after turning WiFi off, it turns on by itself.
A rogue app is turning the Wi-Fi ON. Look into the Permissions.
In Change Wi-Fi Connectivity, you can find list of all apps which can create such problem. Disable all of them or do trial & error.
Edit:
If you can't find this list in Settings, install this tiny app, go to Permissions tab and tap CHANGE_WIFI_STATE
to get the list. This app doesn't let you remove permission, but after knowing the information about an app, you can disable its permission through app's App Info in Settings.
