My seven year old son was playing a game and dropped the phone well I was in the bathroom by time I was able to finish and get back out there and picked the phone up he somehow got into apps and forced stopped some up system app . I know nothing about electronics so I don't monkey with them . I didn't even know you could forced stop them I just know how to download them from the store. After not figuring out how to start it and exiting out of it I don't even know how to get back into it. But now I'm left with a phone that don't seem to operate properly.
