Hello. (Samsung Galaxy S7) All of the sudden this black bar appears at the bottom of my screen, ..it's a little bit over 1/8".....it doesn't bother me except can't see bottom of the icons on text messages and a few apps. My phone and battery are fine, and internet is fine except this black bar blocks things on some websites and text messeges. The phone is about 4 years old tops and works good.... Just feel like I did something to cause this black bar and want to find a solution. I have tried deleting apps, and doing alot of obvious things. i have researched it and can't find a solution...Thank you, Barb
