S4 Black Screen Issue

Problem: Screen is black at the back while a maintenance error notice pops up, it shows internally something below it though.

Solution: If an error message appears on the screen of your phone while it is black then there’s a possibility that the problem is software related. There may be some corrupt data in your phone or the software may have a glitch. Have you recently backed up your phone data? If you haven’t then you should try connecting your phone to a computer running on Kies and backup your data.

If you already have your data backed up then proceed with performing a factory reset on your phone using the hardware keys.

If the factory reset fails to resolve the problem then the phone software may be corrupt. Try to flash your phone software. You will need a copy of your phone’s specific firmware and Odin installed in your computer. Instructions on how to perform this procedure can be found at several of the popular Android forums online.

S4 Black Screen On Dropped Phone

Problem: Dropped the phone on its screen and the screen went black…when u turn it on the screen stays black with a few thin horizontal lines running across the screen…..is it fixable at all

Solution: It looks like the LCD screen is already damaged. You will need to have this replaced. If you have experience in replacing phone parts then you can buy a replacement LCD over at Amazon which usually costs around $100 and replace the LCD-digitizer of your phone. If you are not comfortable in doing this procedure yourself then just bring your phone to an authorized service center and have your phone LCD screen replaced.

S4 Screen Turns Black

Problem: My screen sometimes turns black and just displays the time and I have to shake the phone to get the screen to activate again, and sometimes I go to unlock my screen and when I touch it I get no response but it’s not all the time the phone chooses when it wants to do this and I have to reset the phone or pull the battery out to get it to work again do i need a new screen or digitizer?

Solution: This could be caused by corrupt data or a software glitch. You should first try to backup your phone data then do a factory reset using the hardware keys of your phone.

If the problem still occurs after the factory reset then there may be a problem with your phone digitizer. Since the digitizer is fused to the LCD then you will have to replace this as well. For best results you should bring your phone to an authorized service center and have the display assembly replaced professionally.

S4 Display Discoloration

Problem: Phone has discoloration.  I can see apps in the background.  When the phone is turned on there’s a “black ” spot on the screen, it doesn’t cover the entire screen,but it’s enough to notice.

Solution: You should try to check first if this issue is caused by a software problem by backing up your phone data and doing a factory reset.

If the issue still remains then you may need to replace your phone display. Bring your phone to an authorized service center and have it checked.

S4 Shadow On Screen

Problem: Shadow screen stays on when finished texting.  It covers all of the icons. It won’t close.

Solution: Try to check first if this issue is caused by some form of corrupt data in your phone by wiping its cache partition.

If the issue persists start your phone in Safe Mode. If the issue does not occur then it may be caused by an app installed in your phone. Find out what app this is and uninstall it.

If however you still experience the same issue even in Safe Mode then back up your phone data then do a factory reset using the hardware keys of your phone.

If at this point the issue still persists then this may already be a hardware related problem probably caused by a faulty display. I suggest you bring your phone to an authorized service center and have it checked.

S4 Black Screen But Still Gets Notifications

Problem: I  pushed the home button  it flashes black and French think lines. I then took the battery out to see if it would reset itself. But it didn’t  I now have a black screen and can see  nothing.  My phone still gets calls and I can hear my alerts but I can’t see anything.  My phone was in my front pocket.  I had just downloaded a battery saver app from clean master the night before and did a update . I have not dropped nor damaged the phone.  The  phone did have issues with the battery getting hot and and not holding a charge very long.  I have bought a  new phone but need to get the old phone working so I can transfer data.

Solution: Let’s check first if you can backup your phone data. Connect your phone using a USB cord to a computer running on Kies. If your phone can be detected by Kies then you can backup its data.

To resolve the black screen problem take out your phone battery. Press and hold the power button for at least a minute. This discharges your phone circuit and clears out the RAM. Reinsert the battery then turn on your phone.

If you still see a black screen then this may be a hardware related problem. Bring your phone to an authorized service center and have your phone checked.

S4 Screen Does Not Turn On After Phone Got Wet

Problem: Help! A few months back I got my phone wet, and I put it in rice for 24 hours, just to get the water out. After, it continued to work, but the camera didn’t work any longer – now the screen doesn’t turn on. Every time I charge it the back of it and the screen heats up, but the screen never turns on. I’ve tried holding the up volume button, the power button, and the home button- but it doesn’t work. I can’t even get the “Samsung” screen to pop up. Please help!

Solution: This issue is most likely caused by water damage. When your phone gets wet the problem usually does not show itself immediately. Sometimes it takes days or weeks for the issue to show up. I suggest you bring your phone to an authorized service center and have it opened. This way the internal circuits can be carefully inspected for any signs of water damage.

S4 Multiple Colors On Screen

Problem: Hello. I was on whatsapp attaching pictures from the gallery when the screen suddenly froze, faded and turning green. I could not get access to any apps on the phone. The screen colour then turned a fluorescent purple, almost like a million stars on the screen and eventually it turned a pale pink/purple/white colour. I removed the battery and tried to restart it. I can hear calls and messages coming through from  the little ringing tones but I cannot access anything on the phone. Sometimes there appear lines across in black and green but the colours change and it sometimes flashes. It is most bizarre, as a few minutes before I still took pictures, sent messages on whatsapp and that happened during attaching the pictures from the gallery. I hope I am making sense and I hope you are able to help. Thanks.

Solution: Try checking first if this problem is caused by corrupt data or a glitch in your phone software. Try wiping the cache partition of your phone. If the problem persists then backup your phone data and do a factory reset using the hardware keys.
