S5 Screen Flashes Vibrant Yellow

Problem: Recently, my phone (samsung s5) has begun odd flashes of a vibrant yellow color when used for long periods of time. I went to a store to get a warranty (our yearlong one had not run out). They refused to help, claiming a hairline crack has made the request invalid- even if the flashing had begun before I acquired the crack. This looks Identical to TV static, albeit yellow, and starts with the screen flickering, before going insane.

Solution: What you can do right now is to check if a glitch in the phone software is causing this issue. Backup your phone data then do a factory reset. Once the reset is complete do not install any app in your phone just yet. You should try to check first if the problem still occurs. If it does then we could be looking at a faulty display here. I recommend that you bring your phone to a service center and have it checked if this the case.

S5 Screen Is Flickering Then Goes Black

Problem: My galaxy S5 screen is flickering and goes black, its really annoying and when i get calls i cant see whos calling me or i can’t do anything else till it goes normal again… i don’t know why! Pls help me. Thank you.

Solution: Unfortunately in this case the troubleshooting that you can do is a factory reset. Make sure to backup your phone data before doing the reset since it will be erased in the process. If the issue still occurs after the reset then you have to bring your phone to a service center and have it checked as this could already be caused by a faulty display.

S5 Screen Flickers When Brightness Is Reduced

Problem: I have been having problems with the screen on my S5 for a long time now. I read the article below that address this issue, but does not fix it. Anytime the screen is dimmed a very harsh flicker appears. I have looked at tons of settings and even tried a hard reset. Has anything further ever been found about this? It has been doing it for a year now and I would think if it was the screen going bad it would have done so by now. Thanks so much for any help! https://thedroidguy.com/2015/07/how-to-fix-samsung-galaxy-s5-screen-thats-blank-flickering-unresponsive-110016

Solution: If a hard reset fails to fix the problem then this is most likely caused by an issue with the display assembly already. I’d recommend that you have this checked at a service center.

S5 Screen Is Blank But Responsive

Problem: My phones display is not displaying anything. It’s completely blank but the phone and screen still react to my touch. For example I can unlock the screen by swiping and it makes the the noise of being unlocked but it won’t display anything. I’ve tried a soft reset and tried to do a recovery reboot and to no luck. This same issue happened a few months ago where my screen wouldn’t work for a few days and then it all of a sudden started working again. I’m currently in Sri Lanka traveling and it started to happen again. I’m wondering if the humidity is the problem? Solution: Humidity can be a factor that can cause this problem since. When moisture enters the phone it causes some electronic components to work irregularly. Since you already did the software troubleshooting for this phone then I would recommend that you have this checked at a service center.

S5 Screen Is Unresponsive

Problem: I have an unresponsive screen on my Galaxy S5. The unit has power and I can hear notifications coming through and I can hear my phone ring. I can also see the notification light in the top right hand corner flashing. I haven’t dropped it or had it exposed to water. It started happening when I woke up this morning. I have tried taking the battery out as advised on this site, but all the other recommendations indicate that I need to switch off my device first, which I can’t do because I can’t select that option on the screen when I hold down the power button. Any advice? As for Android version you asked for, not sure, it’s either KitKat or Lollipop.

Solution: Try starting the phone in recovery mode. You can do this by taking out the battery first then reinserting it. To boot into recovery mode press and hold the Volume up, Home, and Power key at the same time. Release all three buttons when the screen flickers and the recovery mode menu appears. If you can access this mode then you should do a factory reset. Take note that this will erase your phone data. If the issue still occurs even in recovery mode or if you are unable to access this mode then you should bring your phone to a service center and have it checked.

S5 Screen Will Not Light Up

Problem: So I have a Samsung s5, now the screen won’t light up in general, I can’t do a recovery mode thing or safe mode stuff because either I can’t see it ( assuming the issue is my backlight ) or something else? I have replaced the battery and tried troubleshooting slightly similar problems and nothing seems to work? When I put my sim card in it will register texts and make notification sounds for them, but I can’t do anything planned, I can’t even tell if the screen is unresponsive because it won’t light up. The led in the front works and the two rectangles beside the hehe home button and the back button light up, they just don’t do anything. Please help!

Solution: This appears to be caused by a faulty display assembly already. I recommend that you bring your phone to a service center and have it checked.

S5 Screen Flickers when Brightness Set To Low

Problem: I am having issues with my samsung galaxy s5. Everytime I turn the adjustment brightness to low the bottom of my screen starts flickering green and the rest of the screen flashing gray. Only time it doesn’t dip that is if I turn the brightness high, also just today I noticed that as I was trying to use my phone it was blank/black but I can hear notifications and when I touch the screen I can hear the touch tones, but can’t see anything

Solution: The recommended troubleshooting step for this particular issue is to do a factory reset. This allows you to check if the phone software is causing the problem. Make sure to backup your phone data before doing the reset. If the reset fails to fix the problem then you should bring your phone to a service center and have it checked.

S5 Bright Green Circle Appears On Screen

Problem: I have a circle that has appeared on my screen of a bright green colour. It is in the top left hand corner and started fairly small but has now grown a little it doesn’t affect the use of the phone but i am worried that my phone could be dangerous to use. I have a samsung S5. Thanks

Solution: Try checking if the issue occurs when your phone is started in Safe Mode. If it doesn’t occur in this mode then it could be caused by an app you downloaded. Find out what app this is and uninstall it. If the problem appears in Safe Mode then backup your phone data then do a factory reset. If the reset fails to fix the problem then you should bring your phone to a service center and have it checked as this appears to be caused by a faulty display assembly.

S5 Screen Glitches With Green Lines When Locked

Problem: I have been having recent issues with my Samsung Galaxy s5 active. When i click the power button for it to go to the lockscreen, it will lock but a bunch of green lines form and it sorta glitches. The same issue occurs when I click the power button to unlock it as well. If there is any way to fix this, please let me know. Thank you

Solution: You can check if this issue is caused by a glitch in the phone software by doing the troubleshooting steps listed below.

  • Start the phone in Safe Mode. If the issue doesn’t occur in this mode then it could be caused by a downloaded app. Find out what app this is and uninstall it.
  • Wipe the cache partition of your phone from the recovery mode.
  • Backup your phone data then do a factory reset.

If the issue still remains then this could be caused by a defective display assembly. I suggest that you bring your phone to a service center and have it checked if this is the case.
