How to fix Samsung Galaxy S5 blank screen & other display related issues

Blank screen issues are very common not just to Samsung Galaxy S5 (#Samsung #GalaxyS5) but any other #Android phones in the market. They can either be caused by a firmware glitch or a hardware problem. The best thing an owner can do is try to find out the cause so that it would be easier to formulate a solution.

A blank screen may be caused by an app that crashed, a firmware glitch or a hardware problem.

I cited a few screen related problems below and I suggest you try to read each one of them especially if you’re experiencing a display related problem with your phone. The first problem is the typical black/blank screen issue. I’ve encountered issues like this before wherein the screen just goes off without apparent reason but the phone is still powered up as it sounds off if messages or calls come in.

Other problems would include screen flickering and flashing while charging, which can be attributed to a hardware problem.

Galaxy S5 screen goes blank but phone still works

Problem: I’m having trouble with my screen going off. The phone will boot up and I can hear all the sounds but my screen is blank and the only way I can get it to turn on is to take the battery out and back in. This especially happens when I drop it (I have a case on it & it’s never been dropped hard). I’ll get it working again and it’ll last for hours then suddenly goes blank again. I’ve had this phone around 1 1/2 years and this just recently started a few months ago. My old phone (Galaxy S3) won’t go past the start-up screen so I don’t have a backup phone. Hoping you can help me with this. Thanks! — Kiera

Troubleshooting: Hi Kiera. It’s really difficult for us to pinpoint what the problem or what causes it because in your case, it’s possible that an app is causing the issue or it could be yet another firmware and/or hardware problem. Let’s set aside the possibility of a hardware problem for now and let’s try to isolate the problem right away…

The first thing I want you to do is boot the phone in safe mode. Here’s how…

  1. Turn the device off.
  2. Press and hold the Power key.
  3. When ‘Samsung Galaxy S5’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

In this mode, all third-party apps are temporarily disabled. If one of the downloaded apps was causing the problem, then the phone should work without any issues in safe mode. However, you need time to observe it to know if the screen still goes blank at some point.

If the problem still occurs in safe mode, it means that the problem could be in the firmware or pre-installed apps. I encountered an issue like this before that was caused by the Smart Remote service that’s displaying on the lock screen. So, I want you to double-check on that first: launch Smart Remote > go to Settings (three dots) > scroll down and uncheck Auto display remote control on lock screen.

Now, the next thing I want you to check is whether your phone becomes laggy or sluggish. Try to open three or four apps and switch between them to see if the phone responds normally. If your phone’s performance is poor, there is a possibility that the device just wouldn’t respond as fast as before so the screen remains blank for a long time.

At this point, if the problem still occurs, it’s time you performed the master reset to give your phone a fresh start. But before you do that, make sure you backup all important data and files as they’ll all be deleted during the process.

  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.

Galaxy S5 Active display blurred & misplaced

Question: I have a Samsung Galaxy S5 Active and for some reason about an hour ago the image on the screen started to blur. The bottom part of the screen would appear at the top, the left side of the screen was on the right side, the pictures were broken, not flipped. I’ve only had my phone for about 3 months, but it was a previously owned phone. I haven’t had a single issue with it until tonight. I tried everything I could think of. Restarting it, turning it off for 10 minutes, clearing the background, everything. The screen still works like there is nothing wrong with the picture. I can still type where the letters should be and it will type it out correctly. I took the battery out for 10 seconds like you suggested and it seems to have fixed it but I would still like to know what was happening to my phone. Please help! — Felicia

Answer: Hi Felicia! Based on your description, I think it was just a glitch and nothing more, although I suggest you continue observing your phone. Taking the battery out for 10 seconds or more and holding the power key while the battery is out often fixes minor firmware and hardware glitches.

Galaxy S5 screen flickers

Problem: My phone screen flickers, and it’s more than just the setting of brightness. If the phone is turned off, I can try and turn it on my hitting the power button. However that takes a while to work because the screen will flash and then go back to black. It will flash with lines through it and just for a second, eventually I can get it to go to the home screen and stay there. Then when I’m using the phone it will flash with lines across the screen and sort of dim out. I’m worried that I will lose the ability to turn my phone on. Any idea how to fix it? — Arielle

Troubleshooting: Hello Arielle. It looks like the phone suffered a minor liquid damage, which often results to random flickers and fluctuating back light. Your Galaxy S5 is “water-resistant” but not “water-proof” so one way or the other liquid can still find its way through it. The thing about liquid damage is that it can further damage your phone so I suggest you send it in to be checked by a technician and probably be cleaned out.

Galaxy S5 screen flashes while charging

Problem: My screen flashes when I’m charging my phone could it be a battery issue? I have to leave my phone on 90 percent of the time rarely turn it off. — Dennis

Suggestion: Try using a charger with 1.8 to 2 Amperes current output. This problem is often caused by a charger with low power rating. It doesn’t just happen the Galaxy S5 but to many Android devices as well.

Galaxy S5 screen displays multiple colors and unresponsive

Problem: One day I was using my phone normally and all of a sudden my screen begins to mess up and change colors. It started off simple; one-fifth of my screen had turned purple. Within an hour the entire screen had turned multiple colors and the entire screen became unresponsive. The phone still turns on, vibrates, etc.. but the screen will not work. What do you think this is? — Jalyn

Troubleshooting: The screen is broken. This is one example of a “bleeding” display. Try calling your phone and if it can receive it, then the problem is just with its display. Screen replacement is necessary to make it work again. If, however, it couldn’t receive your call, there might be another hardware issue. Either way you need a technician.

How to fix Samsung Galaxy S5 black screen of death [Troubleshooting Guide]

The black screen of death (#BSOD) is not new to the #Samsung Galaxy S5 (#GalaxyS5) because some of the early adopter complained about their devices that suddenly died a few weeks after they bought it. The fact is we encountered a lot of related issues way back in 2014 when the device was released.

galaxy-s5-black-screen-of-death

The BSOD is one of the most dreaded issues with the S5 as many had to go through the hassle of going to a shop, wait there for a few hours only to be told that their devices have to be replaced. Well, that’s for the lucky ones. Those who weren’t so lucky ended up having a bricked handset and weren’t eligible for replacement.

In this post, I will tackle this problem once again as we started to receive reports that some owners are once again being haunted by issue and it seems like this time, it’s firmware-related as there are those who said the problem occurred after an update.

Before going into our troubleshooting, for those who have other issues with their Galaxy S5, make sure you visit our troubleshooting page as we’ve already addressed hundreds of problems with this phone since 2014. Odds are that we already answered your problem before and all you gotta is find something similar and use the solutions we provided. If you need further assistance, you can always contact us through our Android problems questionnaire.

Troubleshooting Galaxy S5 black screen of death

The “black screen of death” is actually just another description of an unresponsive display. There have been a lot of users who experienced having their devices turned off on their own and then refused to come back on leaving the screen black or blank.

There are variations to this problem: black screen with blue lights blinking, black screen but the phone plays notifications, black screen with buzzing sound, etc. The point is this problem quite vague and while it clearly speaks of the phone’s current condition, a little more details would surely help us troubleshooters in finding out what really is the issue with it.

But enough talk. Let’s go to our troubleshooting so that you’ll know what to do in case your Galaxy S5 suffers the black screen of death.

Step 1: Verify it’s not just a system crash or frozen phone

System crash happens all the time that this often leaves the phone frozen and unresponsive. This must be the first thing you need to do as it may save you from a lot of trouble if it’s really the case with your device.

Remove the battery and leave it out for 30 seconds and while it’s out, press and hold the Power key for 30 seconds as well to perform a soft reset. This procedure, albeit simple, will refresh your phone’s memory. After 30 seconds, place the battery back in and the the back cover and attempt to turn it on.

If the phone turns on, then problem solved, otherwise, you need to do the next step.

Step 2: Make sure there’s enough battery to power your device up

Aside from the system crash, the other common cause of the black screen is drained battery. So, the next thing you should do is plug the charger in and see if the phone charges. It should display the usual charging icon and light up the LED at the top of the display. If none of these charging signs show, then you must troubleshoot the device with a “not charging” issue and we already have posts for it:

Aside from the obvious reason, plugging the charger in will tell you immediately if there’s a problem with your phone’s hardware so if it refused to charge, here’s what I suggest you do:

  • Connect your device to a computer to see if it responds to that.
  • Use a different charger and/or USB cable to verify further if it’s an issue with the charger or the phone.
  • Try a new or different battery that you know isn’t busted.
  • Verify your device isn’t water-damaged.

Step 3: Boot your device in safe mode

Assuming your Galaxy S5 is charging but still has a black screen that won’t respond, try to boot your device in safe mode to rule out the possibility that some apps are causing this problem. Doing this procedure will put your device in diagnostic state where only pre-installed apps and services are running.

  1. Turn the device off.
  2. Press and hold the Power key.
  3. When ‘Samsung Galaxy S5′ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

Step 4: Boot your device in recovery mode

If your Galaxy S5 cannot boot in safe mode, then try to boot it in recovery mode. In this state, all of the phone’s hardware are powered up only that the Android’s user interface isn’t loaded; it is running on its barebones.

For firmware related issues, the device may still be able to boot in recovery mode but if the issue is with the hardware, then even a flicker on the screen is impossible depending on how bad the issue is.

In case the device responds when you try to boot it in recovery mode, try to wipe the cache partition. Here’s how you boot your phone in recovery mode and how to delete the system cache:

  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.

If you’ve successfully wiped the cache partition and the phone is still not booting up normally, then follow the same steps but this time, choose ‘wipe data/factory reset’ to bring the phone back to its default settings.

Step 5: Send the phone in for repair

This is your last resort in case your device still cannot boot up or still got the black screen of death. Apparently, at this point, there’s nothing much you can do for your device. Anything beyond this is just a waste of your time you let the tech handle the problem for you.
