On my MI5, if I touch the fingerprint reader on the home button, the screen turns off. Then for 5-10 seconds nothing happens, and afterwards I can click the ON button, which shows the lock screen once again.
It appears that others have hit a similar issue with the screen turning on: XDA post, MIUI forum post.
Questions:
- How can I stop this from happening?
- I don't use the fingerprint reader. Is there a way to disable the reader completely? The only ways I found require either root and fiddling with system files (miui post above, StackExchange question), or applying duct tape.
More details:
- This started just now, not after any specific action (didn't update/install/etc)
- I don't have, and never had, any password/pin/drawing/fingerprint - I only slide the lockscreen up to unlock the phone.
- I tried setting a pin, and also pin+fingerprint - same behavior
- I've set "sleep after" to "never"
