Why does an app on my phone keep opening and then quickly shutting by itself every few seconds?

[AC Question]

Whenever I turn my phone on, about every 20 seconds some app will blink on and off by itself. The screen will go black for a second and then will return to what I was doing. I have no idea what to do. Please help!? Thanks!

Go to app manager and uninstall or disable that app.
