whoever having this autofocus issue, after checking out the Chinese MIUI forum, it might cause by misfit of the focus coil and stuck, you could try to tap it a bit harder on camera side, that fix for me.
I am using Mi 5s and camera focus seems having some issue, have a look attached photo, left top corner you could see it's blurry while center is completely normal, I need to tap focus couple times to make blurry go away, any idea why?
Two problems:
1. Whatsapp group message still appear on notification even when it's muted
2. Google Keep notification doesn't show detail, just say "Phone Note" on notification
I am running on Mi 5s
