This is a used phone, linked to the 02 network. I tried to sell it CEX a while ago, but they wouldnt buy it as there is a shadow on any lettering. This was happening when turning the phone on for about a minute and it would then go. I have tried switching the phone on and off to get the phone to do this again to photograph, but it's working fine. The only other issue that when I just charged it to take the photos, it took a while for it switch on under charge. This is just for the phone only.
