Why doesn't my galaxy s4 screen display anything? My Samsung galaxy s4 will suddenly not show anything on the display anymore. It vibrates and such as if everything but the display works. Sometimes it will flash something that looks a bit like part of the android guy, but it flashes so fast I cannot be sure that is what is it or if it just flashes.

I have tried the top solutions that my google search have led me to try:

-Removing the battery and holding volume up and home button for ten seconds.
-Removing the battery and holding the power button for a minute and letting the phone sit for 5 minutes.

It is possible that the phone received a hit during the day that led to this problem but other people who have had this problem have not had it because of any hit or drop and I am therefore not 100% sure that any hit it may have received during the day caused this problem or if it is software related.

My question:
Why doesn't my galaxy s4 screen display anything and how can I fix it?
Try removing the battery and pulling it back in again. Then hold power button + home + volume up for a few seconds until the screen lights up. If nothing shows up the screen make sure your battery if loaded. Try it again and if that doesn't work either. Try exactly the same except you use the volume down now and not the volume up. If that doesn't work it's probably a hardware problem. It's not software because the last update was a few months ago so then it would've been occurred earlier. 

It could be a software problem if you've rooted your phone. Try flashing your stock software on it. You can't see anything but moving through download mode isn't that hard. Power + home + volume down. Wait a few secs, press volume up. Plug into PC using USB and flash stock software using Odin. If it isn't rooted it's a hardware problem. Go to your nearest Samsung Repair Center and maybe the repair is free because of the warranty. Unless it's rooted of course.
