How to fix your blank iPhone screen

Don’t panic! The blank screen on your iPhone 3G, 3GS, 4 iPhone 5s and 6 can be fixed, easily!
Fortunately, I worked out that you can fix this problem by resetting your phone. Here’s how:
Press and hold down the Sleep/Wake button and the Home button simultaneously for at least 10 seconds. The screen will clear out and then the Apple Logo will appear on the black background. When the logo appears it means that the reset is done.
Afterwards you’ll see your screen light up and you’ll be able to breath a sigh of relief!
