My Sister has a Galaxy A20 SmartPhone. She had a Run Tracker App for when She goes Walking. It worked good for a Long Long Time. Then She Came Home one Day and Told Me the Run Tracker App was Going Off the Screen and Stopping. I Told Her how to Clear the App Cache. She did it and it worked for Say 2. Days and did the same thing. So I Told Her to Un Install it and get another one. We started the new one and left it here and it was working but then it started doing what the other one did. Before I start Digging around in the Phone I wanted to Ask if anybody knows what I can do? Thanks for the Time.
