Phone Misbehaves

It looks like you tried to download an Android app onto a Windows phone. That will not work. Try to get rid of the app. If not, the phone may have a way of resetting to go back to the original setup, but you will lose all data if you do, unless they are backed up. Windows, Ijunk, and Android are separate systems and software and apps are not compatible between them. On my phone (Windows) there is a small switch that can be pushed with a pen to reset it, but remember you lose all data including phone numbers and pictures. Read the phone instructions.
