IPhone 6 screen blacked out after Snapchat app exited out by itself. And now the screen won't come back on?

My iPhone 6 screen black out and It won't turn on. I've tried all the trouble shooting tips possible. Except replacing the Whole screen. If I order a full screen replacement from Amazon and put it on my iPhone 6 would the phone be working again

You of course realise that this sounds very much like - A FLAT BATTERY!

  • My iPhone turned off by itself and turned back on while using a app? When I was on YouTube my phone just shutted off by itself then turned on. Is there something wrong with the phone. Also when I click my home button one time the phone sometimes wouldnt come on till the second click. What can I do?
  • My iphone has turned itself off and won't come back on? I have the iphone 4 8g and I have had it for only a month, it is well looked after and I locked the phone then 3 minutes later I tried to access it and it is off and will not come back on, I think I had received a phone call which could have frozen the phone, does anyone know what this is? The phone was purchased from an 02 store and is on pay as you go.
  • My iPhone 4 turned off by itself and won't turn back on? I would try to hold down the home button and the sleep/wake button for 10 seconds but my sleep/wake button does not work. I have also plugged my iPhone up to the computer and to the wall. Nothing is working.
