S5 Screen Constantly Flickers When Brightness Is Low

Problem: I brought this phone a month ago , when the brightness is low it constantly flickers but this stops when I increase the brightness , so If the brightness is high it’s okay . When I off the screen it flickers for a second then goes off , this is the same when I switch on , it flickers then comes onto the homescreen.

Solution: Several owners of this device have also been experiencing this screen flickering problem when the brightness is level is low. Other owners of this model however have not experienced this issue.

Some say that this flickering is due to the AMOLED technology being used. With this technology each pixel emits its own light through the application of voltage. When the display brightness is lowered the voltage passing through each pixel also has to be lowered. It is during this process that the display flickers or pulses.

One way to avoid this from happening is to not set the screen brightness below a certain level where the issue occurs.

There’s  also a chance that this issue can be caused by your phone software. Have you installed any new ap before the issue occurred? That app may be causing the problem. To check if this is the case you should start your phone in Safe Mode. In this mode only the pre-installed apps are allowed to run while apps you downloaded are disabled. If the screen does not flicker in this mode then an app may be the culprit. Find out what app this is and uninstall it.

If the issue occurs even in Safe Mode then you should proceed with wiping the cache partition of your phone from the recovery mode.

One last troubleshooting step that you can do is to do a factory reset. Just make sure to backup your phone data before doing this procedure.

S5 Constantly Flickers In Yellow Green Color

Problem: My screen keeps flickering while I view it & at night when I have it on charge sometimes the screen stays on all night & in the morning the screen is flickering yellow/green color. & as soon as I hit the home button it takes a while for the screen to pop back up. I constantly have to keep hitting it for it to come on finally. It happens everyday & I have not dropped it or anything & I have deleted all apps that I think may have caused this.

Solution: Try checking first if this problem is caused by some form of corrupt data in your phone by wiping the cache partition of your device from the recovery mode. Restart your phone normally then check if the issue persists.

If it does then check if an app you downloaded is causing this problem by starting your phone in Safe Mode. If your phone does not flicker in this mode then the problem is most likely caused by an app you downloaded. Find out what app this is and uninstall it.

One last troubleshooting step that you can do to check if the phone software is causing this problem is a factory reset. Just make sure to backup your phone data before doing this procedure.

If the above troubleshooting steps fail to resolve the problem then this may already be a hardware related issue. Does your phone have a case installed? If it has then take it out of its case first then check if the issue occurs. If it does then I suggest you bring your phone to an authorized service center and have it checked.

S5 Screen Flickering From The Bottom

Problem: My phone fell earlier and since then my screen keeps flickering from the bottom. It stop occasionally. When I try to unlock my phone the screen turns black with red, blue and green dots moving all over the screen for about 10 seconds n then my lock screen comes up. I have tried turning it off and rebooting it. Also tried holding the volume up key, home key and power key till it vibrates then letting go of the power key till it starts to do a factory reset. Nothing seems to be working.

Solution: It looks like this may already be a hardware related problem possibly caused by the drop. If you have already performed a factory reset then I suggest you bring your phone to an authorized service center and have it checked.

S5 Screen Black After Phone Dropped

Problem: dropped phone and phone turns on soft keys and volume button and led light work but screen is black have tried the soft reboot with no luck on a working solution

Related Problem: the phone fell down and it has been blank ever since then,only the menu buttons are still on light

Related Problem: Drop phone it still rings and everything but it doesn’t show anything its black

Solution: It’s possible that the drop could have damaged the phone display since it is now black. Can you access the recovery mode of your phone? If you can then you should try wiping the  cache partition of your device.  If however the phone display remains black even if you try to access the recovery mode then you should bring your phone to an authorized service center and have it checked. It’s very likely that you will need to replace your phone display.

S5 Black Screen

Problem: my phone is turning on, i feel it vibrate but the screen doesn’t come up and it’s just blank,the ‘samsung s5’ label doesn’t come up nothing does but it’s turning on,please help me fix this problem.

Related Problem: first when i turn on it’s not on only shows logo and again same repeating, but now it’s on but nothing displaying, its all black but when i call its ring. please help us in this regards, my phone not in warranty period.

Solution: If your phone has a black screen which doesn’t allow you to interact with the device however the phone seems to be working fine as it can still get calls or text messages then the problem is most likely caused by a defective display.

You should however check if the problem is caused by your phone software by trying to access the recovery mode of your phone. From here you can wipe the cache partition of your phone or do a factory reset. Take note that the factory reset will delete the data stored in your device.

If the problem still persists at this point then you should bring your phone to an authorized service center and have it checked. You may need to have the display replaced.

  1. Happened to me a couple of times now. The problem tends to present when the battery is not fully charged. The phone reports 30-40% charge, but I heard that the percentage shown is not reliable. In any case, plugging in, and recharging allowed me to recover. I also had a 64Gig pixar micro sd card, I had to remove that. I actually did a factory reset the last time around, while I was out of reach of a charger… the phone still acted wonky until I removed the sd card, and charged up the phone to 100%. After that, it rebooted and started working.
    Wonky: I mean sluggish response, the screen touch detection slightly off ( like have to touch it _above_ the icon you want to activate instead of on -it. Also the screen going black periodically )
