S5 Screen Flickers
Problem: Hello, My screen’s phone flickers, but not in the way most people here describe. When there are two contrasting colors one next to each other, the pixels start shaking following that line. For example if there’s white text in a dark background, it becomes hard to read the shaky letters. It improves a little if the image is fixed, but if I zoom in for example, it goes a little crazy for a few seconds. It goes away if the colors are similar. It happens with every brightness setting, but less if it’s darker. It happens all over the screen, but not at the same time, I mean, only a spot of pixels will shake at a time. It happened for the first time the day I received my device. I turned it off and back on and it went away for a month, but now it happened again and it isn’t going away. Any tips would be greatly appreciated and thanks for your time!!
Solution: It looks like this problem is caused by the phone display. Try checking first if this is caused by a software issue by backing up your phone data then doing a factory reset. Once the reset is done do not update the software or app yet. Instead, proceed with checking if the issue still occurs. If the problem still persists then I think the display may be faulty or loose. I suggest you bring your phone to an authorized service center and have it checked.
S5 Screen Flickers Then Goes Black
Problem: When I press the power button to turn my screen on. It flickers and goes blank. I know my screen is on because the back button lights up and I can capture a glimpse of my lock screen before it goes black. I know it’s not a software issue, I believe it is hardware issue. Is there anyway I can fix this problem. Without spending a 100 dollars fixing it.
Solution: You should first verify if the issue is indeed not caused by your phone software by starting your phone in recovery mode. If you can access the recovery mode then I suggest you immediately do a factory reset. Take note that this will delete your phone data.
If the screen is still black even in recovery mode then this is most likely a hardware problem already. Several tests have to be done on the components of the phone to determine which part is failing. The best way to proceed in this case is to bring your phone to an authorized service center.
S5 Screen Goes Black
Problem: When booting phone up I am able to see the Samsung galaxy screen and the Verizon screen but once it fully boot my screen goes black. The screen is still active through this and my soft keys on the bottom still light up. The same happens when I turn phone off…I can see the “title” screens. I have tried all of the safe mode reboots and even completely factory reset the phone and I’m still having the same problem. If I leave the phone powered in and let it sit for a while the screen light up for maybe 30 -40 seconds but then goes black again!
Solution: When trying to turn on your phone and the screen goes black have you tried checking if it is getting any notifications such as phone calls or text messages? If it still gets notification then the issue could be with the phone display. If no notification arrive then the issue could be with the board. Try to check if the issue still occurs with the SIM and microSD card removed. If the problem still persists then I suggest you bring your phone to an authorized service center and have it checked.
S5 Screen Freezes Then Goes Black
Problem: Yesterday everything was working fine until last night. My screen froze and went black and stayed black until I removed the battery. The buttons on the boom stayed lit up for a little while then they shut off too. Now when I restart it by taking the battery out, it will start like normal for a few minutes, then the screen will freeze on whatever I’m on,then go black.
Solution: There’s a possibility that this problem could be caused by an issue with the phone software. If you can backup your phone data then do it first. Next, start your phone in recovery mode then do a factory reset. Take note that this will delete the data stored in your phone.
If the phone can’t access the recovery mode or if doing a factory reset does not resolve the problem then I suggest you bring your phone to an authorized service center and have it checked.
S5 Screen Does Not Wake After Software Update
Problem: Hello, I recently updated my phone within the last couple of weeks. Since the update I’ve noticed the when I click the “home” button on the front of my phone to wake it up so I can use it, it doesn’t always let my phone become available to use. It flashes up like it’s going to work then it goes back black screen. I’ve also used the power button to get my screen to show up and same problem. I would do both those methods to try to get my screen to show up but it takes multiple clicks and a few minutes to get my screen up and going. I haven’t even had my phone for a year. I have a life proof case, so no drastic drops, etc to it. I’ve taken the battery out and restarted my phone still encountering the problem. I’d appreciate your help.
Solution: The problem is most likely caused by conflicts in the phone data brought about by the software update. What usually happens in this case is that data from the old software version is not completely removed during the update. This old data then causes a conflict with the new software resulting in this issue. I suggest you backup your phone data then do a factory reset to resolve this problem.
S5 Flickers At Low Brightness
Problem: Whenever i make my brightness to zero, my screen starts flickering. Half of my screen flickers and sometimes whenever i tap the power button a green light appears on the bottom of the screen. If my phone is not on the lowest brightness, flickering does not occur. Please help. I tried rebooting and clearing the cache.
Solution: This screen flickering issue is common on devices with a Super AMOLED screen especially at low brightness settings. You could try starting your phone in Safe Mode to check if a third party app installed in your phone is causing this problem. Once your phone is in Safe Mode try to lower its brightness. If the screen does not flicker then the problem is most likely caused by an app. Find out what app this is and uninstall it. If the screen still flickers then I suggest you backup your phone data the do a factory reset.
If the screen still flickers after the reset then this problem is most likely caused by a hardware issue. I suggest you bring your phone to an authorized service center and have it checked.
