At first when I turned it on it went to the lock screen and was fine but when I turned it on for about the third time it came up with a factory kit test thing. I assume this is used to test if all the different functions such as the proximity sensor work. I don't know if this has to be completed, which I'm not sure is possible or if there is a way to get out of it. Since then every time I have turned it on it came up with this. The phone is brand new and I got it yesterday. Thanks in advance :)
