Symbols in gray bar

[Dillon Russ]

I hope this is the correct forum, if not I apologize. I have been noticing this strange gray box with what I assume to be Chinese? symbols. I have a Moto X 2nd gen and have run malwarebytes with no issues found. Wondering if anyone has seen this before or know what it could be?



Also now I notice after locking and reopening, I get this screen sometimes:

Only time I ever saw that was when I installed a certain app from outside the play store. Uninstalling it fixed the issue.
