Problem #1: Galaxy S6 “Unfortunately, System UI has stopped” error keeps popping up when taking a screen shot
Hello. So recently my phone has been being strange. Everytime I try to take a screenshot, I can’t and the notification “Unfortunately, System UI has stopped” pops up. And it ONLY happens when I attempt to take a screenshot. It only started happening after I rooted my phone. People told me that I needed to have it rooted, so I trusted them and did it. But it was a mistake. It just slowed down my apps and some of them didn’t work so I unrooted my phone. The other problems have gone away, but the screenshot problem is still happening. I have a Galaxy Samsung S6. This is really bothersome and I don’t know how to fix it. Can you please help me? Thank you. — Kylie
Solution: Hi Kylie. If the “Unfortunately, System UI has stopped” error keeps popping up even after you unrooted your device, you must probably did more than root before. To ensure that you set everything back to official software, we strongly suggest that you flash both Android stock recovery software and stock Android operating system. In other words, you want to restore everything back to their factory state or out-of-the-box condition. This is the only way to eliminate whatever bug is causing this trouble. We trust you understand what we mean given the fact that you’ve managed to root the phone yourself.
Hi there. I have a Samsung Galaxy S6. It was completely fine until one day a yellowish substance started appearing from around the top of the display (internal). Gradually over the course of the day it started spreading further down the display, although it was still possible to see icons and the phone would respond to touch commands. However, once this strange yellowish liquidy type substance had managed to cover practically the whole screen, that is when the screen stopped responding to touch and shortly after the display went dark. The phone still turns on and works in every other respect, but I don’t know why this problem may have occurred! Any ideas? (Warranty people say the damage isn’t covered because they reckon it was caused by physical damage). Cheers. — Conor
Solution: Hi Conor. We don’t know the full history of your device but based on the problem description, the LCD may have been permanently damaged for some reason. That’s the most probable reason why there’s a liquid substance that seems to come out of nowhere. To fix the problem, the screen assembly needs to be replaced. Some technicians may try the replacement of the LCD only but we strongly recommend that you let them replace the entire assembly itself to avoid complications.
There are a number of websites that offer do-it-yourself guides on how to replace the screen assembly but be warned that hardware repair is inherently risky. If you haven’t tried hardware repair or parts replacement before, you may find the instructions tricky and the actual repair difficult. There’s always a chance that you’ll end up bricking the phone permanently. If you’ll find the DIYs challenging, simply send the phone to a qualified repair shop.
Hi there! I’ve been reading through your very informative post on the Samsung Galaxy S6. It’s really appreciated to have a source such as your own that is easy to comprehend and very helpful!
I’m having a problem with my Galaxy S6 — just over 1 year old — not keeping a charge. I can use both the Samsung provided charger and USB cable or a non-Samsung charger and either way it will supposedly charge the battery to 100%. However, it only takes approximately 15 to 20 minutes before it takes a major dump and it says it is at 1% critical mass!
I have turned it off to try and reboot it to no avail. I obviously have tried different chargers and again it will charge but discharges in minutes compared to holding a charge nearly all day before.
Any insight you might be able to provide would be appreciated – I am trying to figure it out with some troubleshooting of my own before beginning the often tedious task of working with a tech support rep. I don’t wish to purchase a new phone if I don’t have to but…
Thank you so very much! — Anna
Solution: Hi Anna. There are a number of reasons why a smartphone appears to fail to hold a charge even when it’s actively charging. Let’s discuss each of them briefly.
Lithium-ion battery aging
A Lithium-ion battery like the one in your phone can’t run forever. It ages and degrades its performance the moment it leaves the factory. If you’re a heavy smartphone user and has been using the phone for some time now, the battery has most likely lost significant capacity to hold a charge.
All battery-related problems are actually chemistry problems. In an ideal world, the entire process of ions travelling between cathode and anode and the resulting power generation from such movement should go on forever. In reality, the process degrades the cathode over time, resulting to loss of capacity. The more the battery discharges (when you use it), the more you shave off a time from its maximum life. Exposing it to extreme temperatures (hot and cold) can hasten battery deterioration and it’s only a matter of time before you realize that you need to charge it more often than usual.
Even when you don’t use it, a Lithium-ion battery degrades over time. It’s not uncommon for even high-end lithium-based batteries to lose 20% of their capacity even if kept properly in a year. A typical smartphone battery usually starts showing symptoms of capacity loss after 200-300 battery charging cycles (a cycle is the process of charging a battery from 0% – 100% then using it again until power level is back to 0% again). If you charge your phone at least once a day since you unboxed it, you should be able to observe significant capacity loss at this time.
Apps and services running in the background.
One of the main reasons why phones no longer appear to charge at their usual rate can be due to apps and services running in the background. While most system apps are designed to continuously run without user input, some apps that are not so critical may also do the same. This means that they use battery power even if they are not actually needed by the system at all times. Try to navigate to Settings>Battery and see what apps are eating up huge chunks of your battery. If you see a third party app that you don’t usually use but still manages to place high in the list, that should be enough reason for you to manually stop it or even uninstall entirely. In Android Marshmallow, you can Force Stop an app by heading to Settings>Memory>Memory used by apps.
Better still, simply turn the phone off while charging to ensure it charges faster than what it’s doing now.
Although there has been no official word from Google or any hardware makers like Samsung that there’s a specific malware causing symptoms like the one you’re experiencing right now, it doesn’t mean it’s impossible. Right now, most forms of Android malware are designed to push ads and sometimes steal information rather than to destroy devices. The current crop of malware can still cause significant battery drain issue though as they can take control of your phone or root it so they can install more apps that can show ad pop ups. These unauthorized app installations are mostly design to run associated services in the background all the time helping drain battery faster. If you noticed persistent ad pop ups lately, that may be a sign of a malware infection.
The most effective way to address malware infection is by flashing stock firmware. If you think your phone is infected, approach your carrier or Samsung so they can help you flash the device.
Defective charging port
Although a defective charging port usually results to complete charging failure, in some cases, it also leads to intermittent/slow charging and battery drain while charging issues. If the phone is having difficulty charging properly, then the battery drain issue you’re experiencing right now may be the result or side effect of a defective charging port. In this case, you want to bring the phone to a repair shop (Samsung or third party) to have it repaired.
In some cases, the main reason why a smartphone seems to be failing to hold a charge is due to the fact that the battery is not working properly in the first place. Some batteries can become erratic after some time (due to natural aging process) while others can be damaged due to other factors. Because a Galaxy S6 does not have a removable battery pack, it’s not easy to physically check the battery itself. If you suspect that battery may have gone bad, let Samsung or any relevant party open the phone for you. Keep in mind that opening the back portion of the Galaxy S6 case to access the battery will void whatever warranty you might have on the phone.
Other unknown hard issue
Sometimes, problems with other components can affect the battery as well. This is especially true after accidentally dropping your phone or exposing it to moisture or liquid. If your phone has been dropped or became wet before, you should really consider having its hardware checked.
Hi Droid guy. I have a Samsung Galaxy S6 and recently have been experiencing trouble with it shutting off. I don’t see, hear, or feel it shutting off so it apparently is happening when either my screen turns off from inactivity or I shut the screen off. When I go to turn on my screen (either touching my home button, or my power button) it doesn’t do anything. If I try powering it on (holding power button) I get nothing. I also tried plugging it in and hitting the button. Because it doesn’t happen while I’m using it, it took me a while to realize the timing of it. But I’ve narrowed it down to be when I’ve used my camera or even viewed my Gallery. What brought that to my attention is I’m now experiencing issues with viewing photos (sometimes they won’t load, or they load and freeze) and videos (the audio plays but the picture freezes).
Because I use an Otterbox cover the phone is in pristine condition, and I still have good battery life, so I’d hate to have to replace it. — Donna
Solution: Hi Donna. There may be an unknown software glitch that causes this behavior. Because you did not elaborate on what troubleshooting steps and solutions you’ve tried so far, we’ll provide all of them for you and for the rest of users who may find this blog.
Wipe the cache partition
Sometimes, system updates and app installations can corrupt the system cache, resulting to erratic behavior of some apps in turn. To ensure that the system cache is up-to-date, you must always wipe the cache partition after installing a system update or after you install an app. Here’s how it’s done:
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
- When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
- When the Android System Recovery screen appears, release the Volume Up and Home keys.
- Press the Volume Down key to highlight ‘wipe cache partition.’
- Press the Power key to select.
- When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
Observe in safe mode
Another good thing to try is to check if you’ve installed a third party app that may have caused other apps to work erratically. You can do this by restarting your phone in safe mode. Safe mode prevents third party apps and services from loading so if you notice that the phone works normally (as far as viewing photos and videos are concerned), that’s a sign that a third party app is indeed to blame.
Safe mode won’t help you pinpoint the offending app though so you want to do trial and error in identifying it. This is done by uninstalling apps one by one, then observing how the phone works after every uninstallation.
Below are the steps on how to boot your phone to safe mode:
- Press and hold the Volume Down and Power keys for 20 to 30 seconds.
- Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
- Your phone should continue booting up and you will be prompted to unlock your phone as usual.
- You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.
- Observe the phone for a few hours.
- To boot back to normal mode, simply restart the phone.
Update apps and Android
Sometimes, a simple troubleshooting step is the most effective solution. Make sure that you only install compatible apps and you install their updates regularly. You also want to install whatever available system update there is. Updates are released for a reason so avoiding them is not really wise.
Wipe the phone clean via factory reset
If you want to know whether or not an operating system level glitch is causing your problem, doing a factory reset is highly recommended. Not only does it eliminate existing bugs but it also forces the phone to restore all software settings back to default. If the issue persist after a factory reset and without installing any app, that just means that there’s an unknown hardware issue behind it. However, if the phone appears to work normally after a factory reset (with and without apps), then a glitch may have simply developed overtime.
Hey guys. I’ve got a rather significant problem with my phone here. I have a S6 Edge, and it’s about a year old. Last night I was out, and took my phone out, browsed a little, and put it back in my pocket. Not ten minutes later when I get home, the phone is totally unresponsive. Battery should not have drained that fast, based on how much it had left. Now all it does is have a weird purple/black checkered pattern on the screen when I hold the power button.
Also, the battery seems to be working, as it does pull power, though no light comes on to indicate it. It also doesn’t get detected by the PC when I plug it in. How do I fix it, or all else failing, at least access the data on it? Thanks for your help. — Dmitry
Solution: Hi Dmitry. Before you can consider accessing your files, you must first ensure that the phone turns back on. Unless you can do that, those files are good as gone.
Needless to say, your first task in this case is to see if you’re still able to power your phone back on. Because you can no longer do that in normal mode, you must try to turn it back on by doing other hardware button combinations. Keep in mind though that not all alternate boot modes will allow you to access your phone’s internal storage device. Below are the things that you can do to boot your phone to another boot mode:
Boot in Recovery mode:
- Charge the phone for at least 30 minutes.
- Press and then hold the Home and Volume UP keys, then press and hold the Power key.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
- When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
- Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
- You can either wipe the cache partition or do a factory reset when in this mode.
Boot in Download Mode:
- Charge the phone for at least 30 minutes.
- Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
- Wait until the Download screen appears.
- If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
- Use Google to look for a guide on how to do it.
Boot in safe mode:
- Charge the phone for at least 30 minutes.
- Press and hold the Power button.
- Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
- Continue holding the button until the phone finishes rebooting.
- Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
- The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.
