Okay so I have an IPhone 5S. Randomly whilst at work it turned off and when I couldn t turn it back on I decided to put it in to charge. It showed the start up screen with white background and then turned off then started again on its own again and again.
I then connected it to my computer and put it into recovery mode but about 15 minutes later it started doing the on/off thing again where it would have the starting screen but this time flash a bright red before turning off. I don't know what to do.
Help?
