SStarting today the numbers and letters on the lock screen turned into white squares. And started to appear into the notifications. How can this be fixed.
Thank you,
I did not install anything lately but upgrading the system to the Lollypop. Howeve, powering off and on the phone worked. I do not know if it fixed completely the problem, from what I have been reading on other sites. But workers for know. And this makes it less annoyin.
Thanks again.
