Bluetooth periodically switches off – Android Enthusiasts Stack Exchange

The Bluetooth on my Android phone periodically switches off.

This is a problem because I use a “Tile” on my keys. To find my keys using my phone, and my phone using my keys. And after the Bluetooth switches off, this doesn’t work.

phone: Xiaomi Max 2

Android version: 7.1.1

MIUI version:

The best advice I’ve gleaned from the internet so far has been to give the “Bluetooth Share” app all the permissions it needs. This seems to have lengthened the time it takes before the Bluetooth switches off.
