The #Samsung #Galaxy #S5 is a former flagship device that uses one of the best displays available for a smartphone. This model uses a 5.1 inch Super AMOLED display that has a resolution of 1080 x 1920 pixels at 432 ppi pixel density. Needless to say, the images that appear on the screen are crisp and vivid making this phone great for various multimedia use.

S5 Screen Will Not Turn On
Problem: The screen will not turn on. It remains blank. The phone will turn on, because I can hear the sounds it makes when it used to work before. I have even received a call from someone and swiped a blank screen to answer. I’ve turned it off and restarted. I’ve removed the battery and put it back after 15 or so seconds. No result. on some occasions a strip a light/illumination down the full length of the right side of the screen appeared, half a second or so. Nothing very bright though. Only had the thing a month.
Solution: You should check if the same issue occurs when the phone is started in Safe Mode. If the screen works in this mode then the problem might be caused by a software glitch. You’ll have to do a factory reset in this mode. Take note that your phone data will be deleted when doing the reset so make sure to have a backup copy.
If the screen remains blank even in recovery mode then the display assembly might be damaged or there is a loose connection between the display and the motherboard. If this is the case then you will have to bring your phone to a service center and have it checked.
S5 Blank Screen
Problem: My S5 crashed while i was in the gym. The phone was running super fast and jumping screens and getting jammed so i turned it off. Now it vibrates when i turn it back on and the blue LED screen comes on also the two bottoms at the bottom light up ( Page button and return to last page button) I have tried taking battery out and holding power button then putting battery in and restarting but makes no difference. Also tried holding volume up power and home screen all together but still just a blank screen with the lights. Any other ideas?
Solution: You will have to perform the same troubleshooting steps as the issue we have addressed above. Start your phone in recovery mode first. If the screen works in this mode then there’s a chance that the problem is caused by a glitch in the phone software. You should try to do a factory reset in this mode. Make sure to have a backup of your phone data before doing the reset as this will be erased in the process.
If the screen doesn’t work even in recovery mode then the display assembly might be damaged or it suffers from a loose connection to the motherboard. If this is the case I suggest that you have the phone checked at a service center.
S5 Screen Flickers When In Low Brightness
Problem: When my phone is on the lowest setting for brightness (Including just a bit higher), my screen starts flickering. At first it was a bit of green lines on the screen, but developed to being dense. Now it is practically tinting my screen orange and green, flicking from time to time. It has made my phone extremely difficult to use on low brightness.
Solution: While most phone’s using a Super AMOLED display exhibits some form of flickering issue at low brightness settings it’s not to the point of making the phone unusable. To troubleshoot this issue try starting the phone in Safe mode first then check if the issue occurs in this mode. If it doesn’t then it might be caused by an app you downloaded. Find out what app this is and uninstall it. If the issue still occurs even in Safe Mode then I recommend that you backup your phone data then do a factory reset. Once the reset is done do not install anything in your phone yet. Try to check first if the issue still occurs. If it does then this might already be caused by a damaged display assembly. I suggest that you have this checked at a service center.
S5 Screen Unresponsive
Problem: I have a combination of problems. It started with the yellow-green flicker that i have been reading about. On low brightness or power-saving mode, the screen used to flicker. I tried safe mode as well as a hard factory reset, wiping everything, but that didn’t help. Keeping it on max brightness, although battery-draining, helped for a few days. Then, the screen turning-on started. Not that the screen doesn’t recognize I’m touching it (the bottom buttons light up when I do), but it’s very frustrating to actually turn it on. I can press the power and home button sometimes 10-15 times before the screen actually turns on (it’ll just flicker for a second then turn off), though it is responsive even if I can’t see it. Even the max brightness doesn’t prevent this. This started without any sort of trauma (dropping on the ground, falling in water, etc) and I don’t know how to fix it. It’s only a year old and I really don’t want to have to buy another one. Any thoughts? It’s getting to be past the point of inconvenient and almost to the point of not being usable. Is this a problem with all Androids? if I have to buy a phone, do I need to get an iPhone instead? I’d rather not, but I don’t want to end up with this issue again if I do wind up having to purchase another phone.
Solution: It looks like this is already a hardware problem possibly caused by a defective display assembly. I recommend that you have this display checked at a service center. It’s very likely that you will need to have this replaced. You should also consider getting a new phone instead of having the display replaced a new screen costs around $200 which doesn’t include the labor charges.
