So I'm locked out of my phone in a way that doesn't seem to be able to be fixed by anything. I didn't forget my password, the bottom row of my keyboard just stopped working. I've switched through samsung's default, swype, and a.i. keyboard plus, same thing on all three. The placement of the "enter" button is preventing me from being able to unlock my phone. This is also a new thing as well, just happened this morning. The pixels don't look messed up, I didn't drop it last night, nothing should be causing this problem. I need a fix for one or the other, either a way to unlock my phone or a way to fix my screen.
Running android 5.0.1 on a samsung galaxy s4.

Also, I'd prefer if you have answers other than wiping my whole phone. It's an option but a terrible one because I can't back up anything since I can't get past my lockscreen.
