My iPhone 6's bottom left hand corner isn't broken?

My phones bottom left hand corner is broken. Not cracked broken but I can't really get acess to numbers or punctuation. I can get to caps and extra keyboards but I have to press the corner of the globe button to get to it. And when the emojis keyboards is open I can't get out of it. I did download an app that required added a thirdparty keyboard and I think that is why the screen isn't receptive in the bottom left hand corner area because it was working just fine before I downloaded it. (I deleted it already) I'm going to try to restart my phone though.

Update: restarting phone didn't help
