Why can't my camera focus

Is this still an issue? What do you mean by can't capture texts? What version of Miui are you running? Apparently it was an issue on certain versions of the software. Mine works fine, its an M3 global phone, and I have been through all the updates. Also could be an issue if you got a non global version of the phone, as some features are disabled in version of the M3 that were designated for specific countries.
