This could be a Hardware issue. However, let do a quick reset and see how this works out: Go to Settings Select Apps Select All (Look for ALL on top menu or swipe to the right to get to ALL) Select Google Services Framework and tap Clear Data. Turn off (shut down) your device and turn it back on. Test the phone to see if it will black out again. Hardware issue：get new here Does the phone have any physical damages?
Do It Yourself Arguably the trickiest option here and one that’s only right for those happy to open up their beloved device and void any remaining warranty. Depending on your model, this can either be remarkably easy or a bit of a drag. The iPhone 5 made it a lot easier to replace the display assembly but replacement parts are still very expensive at over $200 at least for the front construction. Remember – you cannot replace only the glass but you must replace the whole construction: glass, digitiser and LCD included. If you were to buy this replacement iPhone 5 screen at around $ 87.88, you could save around $80 on the Apple cost by repairing an iPhone 5 yourself assuming your time is free.
