IPhone 5S Pink/Purple Screen and also unresponsive?

My IPhone 5S screen is turning pink/purple after like 30 seconds of using it then my screen is unresponsive will not move at all and also the sceen turns black after that. I have no water damage this has been happing for about two days and i restarted my phone cleaned my screen. Also the screen turns purple and makes my screen looked cracked but after I restart my phone it goes back to normal for only 30 seconds and has the same problem Help!

Maybe try to get it fixed?

If it is within warranty, call apple support and work out how you can send it to them. This is a hardware issue, therefore it can't be fixed with apps etc.(More than likely hardware, I'm not a technician so not definite). If it is not within warranty, you can get a quote or taek it in to an electronic specialist or phone fixers to see 1. If it is fixable 2. How much they will charge and if it is really worth it.

If you do give your hone to anyone, apple or a repair shop. Please BACKUP All your photos, phone numbers etc. They could accidentally wipe your hone, or deliberately and you won't get any compensation.
