Why bluetooth always on? It just drain the battery when you don't really need it at all.
Bluetooth is always on for Mi Band 2 to notify me on calls/SMS with vibration. My phone is 24/7 in silent mode (alarms only) and not always in my pocket so having "vibration-only" wearable device is very useful for me. Sorry I didn't mention that.
Please fill in all fields such as Backup and System Image software.
It's a Android One phone. I'm not sure if the stock Google Backup counts as Backup and System Image software.
I suggest to disallow personalized ads and never send anonymous data and statistics...
Thanks for the suggestion.
I've reset Advertising ID and then enabled "Opt out of Ads Personalisation" in Google settings.
I've also disabled Mi Services "Send diagnostic data automatically" & "User Experience Program" (Xiaomi is this device manufacturer). I hope I don't miss something.
