How to fix Samsung Galaxy S5 screen that’s blank, flickering & unresponsive

In this post, I will answer four of the screen-related problems with the Samsung Galaxy S5. The issues I included here are from our readers. The first one is about the blank screen that started after the phone fell and hit the floor. Common sense would tell us the drop may have messed up the phone and we really don’t know the extent of the damage. If you encountered this kind of problem as well, read on to know what needs to be done.

The second problem is about the screen flickering when the brightness is set at a certain level. While screen flickering issues can either be hardware or firmware problem, in this case I think it’s the firmware that has an issue because if it were the hardware, the screen will flicker randomly even if the brightness is set at the highest level.

The third and fourth problems are about the screen brightness fluctuating and the top portion being unresponsive. The latter started after the lollipop update. Learn how to address this issue and why it may be normal for the Galaxy S5 screen brightness to fluctuate.

Before going into the specifics, if you have other concerns with your phone, visit our Galaxy S5 Troubleshooting page as we already addressed hundreds of problems since the device was released.

Galaxy S5 screen went blank after hitting the floor

Problem: Hi I dropped my Samsung Galaxy S5 from my dining table. It fell onto the floor and when I picked it up. It had a blank screen but the soft keys are lit up and when I press them I don’t get any response or vibrations. It has been 1 week now and I have tried all kinds of solutions found on youtube and google but no success.

Can you help me please, I can’t live without my phone and its not insured silly me and I don’t think I can afford to get it repaired. Many thanks.

Troubleshooting: Most of the time blank screens are caused by minor hardware or firmware glitch. The fact is a simple reboot can fix it but that is always not the case if the problem is caused by liquid or any physical incident. In this problem, our reader made it clear that the blank screen with his Galaxy S5 started after the it fell on the floor. Of course, it’s physical damage but we really don’t know as to what extent. But when it comes to these issues, what you need to do is pretty straightforward–if you can’t fix it on your own, then find someone who can.

But before you send your phone in for repair or checkup, do a soft reset first and try to boot it in recovery mode. Here’s how and why…

  1. Remove the back panel of the phone.
  2. Pull the battery out.
  3. While the battery is out, press and hold the Power key for a minute. That should be enough to drain stored electricity in some components.
  4. Place the battery back in.
  5. Attempt to turn the phone on.

Soft reset is very effective against minor hardware and firmware glitches; it refreshes the memory of your device as well as drained stored electricity in the components. If your phone didn’t turn on after this, then try booting it in recovery mode.

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.

Do this procedure just to verify if the phone can boot up in that mode because if it can, then the hardware is fine, otherwise, go ahead and have a technician take a look at it.

Galaxy S5 screen flickers when brightness is set at certain level

Problem: When the screen brightness is lowered to the lowest setting, the lower half of the screen begins to flicker. Raising the brightness a few notches stops the flickering. I have not dropped the phone or exposed it to water – the issue started out of the blue and it’s driving me mad! Please help.

Troubleshooting: Screen flickering issue can be hardware or firmware problem and since there’s not much information here, you have to other option but to rule out the possibility that it’s just a firmware issue (which I really think it is) by performing hard reset. Of course, backup all your important data before doing that as they will be deleted.

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

If the hard reset failed, then have a technician check the problem for you.

Galaxy S5 screen brightness fluctuating

Related Problem: My screen seems to be fluctuating in brightness.. Just so slightly. And my auto brightness adjust isn’t on. Wasn’t sure if this is something I need to worry about progressively getting worse or what.. Just get back to me if you can!

Troubleshooting: When you actually look closer, the screen in your Galaxy S5 fluctuate even if the auto-brightness is disabled. The traditional LCD screen has backlights that project light through the pixels and brightness can be adjusted by actually dimming these lights. Your Galaxy S5, however, uses the AMOLED technology where every pixel emits light. Brightness is adjusted by changing the amount of current that flows through these pixels. Reduced current may cause this “fluctuating” or pulsating brightness and more often, it happens when the battery is almost empty. So, to answer your question, you really don’t have to worry as long as the phone didn’t endure any physical or liquid damage.

Top portion of Galaxy S5 screen is unresponsive

Problem: When my phone is turned on, for the first 5-10 minutes, the touch senses for the top of my phone doesn’t work. I can pull down the screen menu. This started after the lollipop update. But it recently started to do it after its been on a while. Also, it started getting really “jittery” like getting stuck on an action then repeating it over and over.

Troubleshooting: How’s the performance of your phone after the update? If the performance is poor, then it could be that the unresponsive part of the screen is caused by freezing or lagging, which is firmware-related. We can spend all day trying to find what the culprit is without the guarantee of a resolution. So, to save you from all the hassles, try wiping the cache partition first, and if it didn’t work, backup your data and perform hard reset.

Wiping Cache Partition 

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Doing the Master Reset

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

I hope this helps.

  2. My S5 is flickering yellow in low brightness and in darkness. Nothing works, hard rest, wipe cahce, turn off auto brightness, install app, disable overlat. Only works put brightness at the max. But is not a solution because in this mode the battery drain fast.
    The display screen is new, i take the phone to the support center to change it. And the tell me that was repaired, but now is flickering. Anyone know a permanetn solution that not drain battery?
    My mobile was in support center, and i don’t think after reapir ther is again an hardware problem, i think is a software problem.

  3. Thank you so much for all the informative suggestions troubleshooting the blinking monitor on the Galaxy S5. However I found the issue to be the automatic brightening settings to be faltering. If you just change the setting from automatic the problem will be solved. Leave that setting off for a few days and it should reset and work normal.

  4. Thank you so much for your help with my flickering screen. It was driving me mad. I was about to get a new phone. You ere spot on I austen the brightness and everything was OK thanks again. Xxxxxx

  5. How can it be, that so many people have the SAME problem with their Samsung 5s,
    and still, Samsung doesn’t take responsibility over its manufactory defect??

  6. Your flickering screen advice saved me!!!!! Thank You!
    I have had minor flickering problems with my screen; however, today I was babysitting my 2 year old neighbor and she loves to play with my phone and swipe back and forth and pressing buttons like a teenager. The screen went nuts with flickering. I restarted with no luck, turned off the phone with no luck and thought oh my gosh, this phone is fried.
    I Googled the problem and found your site and followed your suggestion to change the brightness level. BAM!!! My screen returned to normal. It still has minor flickering but your advice saved me.
    THANK YOU!!!!!!

  7. my s5 started flickering so googled and found your page, turned up the brightness and seems to be fine now, many thanks

  8. Green flickering screen on S5 fixed by using suggestion on Samsung blog
    Go to ‘settings’
    Select ‘Display’
    Turn off ‘auto adjust screen tone’
    Then turn off phone and restart.
    No reset or safemode needed.
    Can even switch on ‘auto’ by brightness slider and no green flickering occurs.
    Phone works like new.

  9. My screen has been getting worse over several months. It flickers at low darkness, sometimes has a severe yellow tint on the screen (which doesn’t show up on screenshots) and on the bottom quarter of brightness adjustment, most of the bottom half and sections of the upper half of the screen turn almost completely yellow with lines throughout the screen. However, by turning the phone upside down and pressing the screen onto a hard surface (specifically a spot to the left and slightly below the camera), the yellow tint will disappear. The lines and flickering won’t go away unless I turn my brightness up. Is there a permanent solution to this problem? Does anyone know what part of the phone I need to replace? Thanks!
