This is a video tutorial for installing custom firmware on mi band 4 in which we can set custom screen off time according to our wish.
* NOTE- If you want to go back to stock firmware uninstall the custom mi fit application and install the mi fit app from the play Store. It will update the mi band to stock firmware.
