My iphone turned black and is fixed, i just want to know why?

So my iphone 4 just went black and it didn't do anything so i went on the internet and fixed it and its all fine but i want to know why it happened. I didn't drop it or do anything it just went like that out of the blue

You should've thrown your phone… Buy htc one or samsung s3 or xperia s… C'mon android phones r better.

Do you realize how useless this question is

  • My iphone went black but not totally black and i don't know what to do? So i was on my phone and i opened up the snapchat app and it just froze and went black but not totally black like how it is when it is off you can still see a little light. I really have to have it for tomorrow and i don't know what to do, i tried pressing the home and top button at the same time but its not doing anything.
  • 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 4 froze, screen turned green and turned off? I was playing a game i regularly play when it froze. I let it sit there for a couple minutes, I pressed the home button and the screen turned green, It was green for a minute. It shut off and won't turn on. I plugged it into the charger 20 mins ago and still no response. Also, my power button broke a whille ago. What can i do? Keep it plugged in until it turns on or should i unplug it for a couple days?
  • If I turned my iPhone 5s off for two years and turned it back on, would it still work? I curious. If I didn't take it off my iPhone plan thingamajig and simply shut it down, no communication for two years, would it be able to come back on?
