Why is my text keyboard disappear mid text and why are videos stopping 35 seconds in?

[AC Question]

I have a galaxy s7 edge...

I'll be texting and my keyboard disappears on me mid text. This started about mid last week. So I turned my phone off, nothing. Updated it, nothing. But after I updated it videos began doing the same thing. They'll play for about 18-25 seconds and stop as though someone pressed pause? So, I did a factory reset, nothing again... What else can I do? Take it into a verizon store?
