Problem #1: Galaxy S5 shutting off by itself | Unable to restart S5 after it froze

Hi there. Hoping you can help with my Samsung problem. I’ve not come across this problem in any other blog or website so far. Problem is, my Galaxy S5 mini will just randomly shut down while I’m accessing it. Only way to restart it, is to remove the battery first, then start up as normal. Without removing the battery, it won’t restart. It only happens when I’m working on the phone, not when it’s not in use. Regardless of battery charge. It has happened while accessing various apps WhatsApp, Snapchat, email, Gmail, Calendar, Maps. There really is no trend in when or which app. I do get the feeling though, that it happens most often when I’m most demanding of the phone and possibly “going too fast,” if there is such a thing for a phone! I may enter WhatsApp, then quickly tap back, back again, and then tap on Gmail. Like it’s too much processing for its small brain to handle, then it shuts downs! Other times, I simply dial someone and it dies before connection. Or I move the camera from portrait to landscape and it shuts down. Not always though, no consistency in what is causing it.

I also need to allow it some time after battery out, battery in, restart. If I use it too soon after restarting, it will shut down almost immediately again. And I restart the process of battery out, battery in, start up.

It used to be my husband’s phone, he never had any issues. Within a week of me having it, it started happening. So I thought it was an app, but I can’t figure out which one. Thought it was the SD card as I moved that over from my old Samsung (which experienced the “Camera Failed” error). removed it for a week but the problem persisted even without SD card inserted. Possibly something to do with the dimming effect? It’s happened a lot in bright daylight but I’m possibly grasping at straws now! I’ve tried clearing caches and factory reset but no success. Any guidance or advise would be greatly appreciated. Thank you for a great website! — Ira

Solution: Hi Ira. If you want to get to the bottom of the issue, you should do more troubleshooting steps. Because factory reset did not fix the issue, the problem may be caused by an app or something in the hardware department.

Factory reset, then observe

We don’t know if you tried to observe how the phone works after you factory reset it but if you didn’t, make sure that you do it this time. Try another round of factory reset and observe how it works when there are no apps installed. Be sure to give it at least 24 hours so you’ll notice the difference. It’s important that you don’t install any update or any app during the observation period. If the problem won’t occur, you can assume that an app is causing the problem. To determine which of them is causing it, you must install apps one by one, making sure to observe how the phone works after every installation. This is the only way to identify the culprit.

Battery recalibration

You can also try to recalibrate the battery to make sure that you retrain the operating system in detecting the true level of the battery. Here’s how to do it:

  • Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  • Turn the phone on again and let it turn itself off.
  • Charge the phone without turning it back on.
  • Wait until the battery says it fully charged to 100%
  • Unplug the charger and turn the phone on.
  • If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  • Unplug the charger the turn the phone on again.
  • Use the phone until you drain the battery down to 0.
  • Repeat the cycle once.

Battery replacement

On the other hand, if the problem remains after a factory reset observation period, you can bet the issue is hardware in nature. Try to get a new battery and see how it works. Sometimes, a bad battery can manifest in random shut down issue so this is must-do troubleshooting step.

If a new battery won’t make any difference, there must be a motherboard fault causing it. In this case, you need to send the phone in to Samsung for repair or replacement.


If you noticed the phone is getting warm before it shuts down, that may be an indicator that the device is overheating. To prevent damaging internal components, electronics are, most of the time, designed to shut down automatically. In this case, you simply have to let the phone cool off before using it again.

Other times, the system may simply get wrong inputs from its sensors telling it that it’s overheating. This is usually a hardware problem and is an indication of motherboard damage. You need to have the phone replaced.

Problem #2: Galaxy S5 keeps restarting on its own

My phone was working fine when I forest got it in November. I usually wouldn’t every turn it off though as I used it for several alarms. One night, I was having Internet issues so I restarted my phone. After I restarted it, the phone started restarting on its own constantly. It restarts itself until the battery dies. Oddly, the phone doesn’t seem quite as likely to restart if I am using it. I did a factory reset after trying to boot in safe mode. The same problem occurred in safe mode. Then I sent it to Samsung under warranty and they didn’t do anything. The same problem still occurs. Do you have any suggestions? — Kassa

Solution: Hi Kassa. We can’t possibly know what’s causing the problem given how little information you provide here. We don’t know the full history of the device and the status of its hardware so all we can do is speculate. Random reboot issues can happen due to a variety of reasons so you must narrow down the possible causes yourself if you want to know what it is.

The general rule in this case is to start with possible software causes. Troubleshooting steps like wiping the cache partition, booting and observing in safe mode, installing updates, recalibrating the battery, performing factory reset, and flashing stock firmware must be done. If you’ve already tried all of them, there must be a hardware problem behind the trouble. Again, there’s no way for us to know what particular component may be failing. Only a thorough hardware check can do that. Some hardware problems can be tricky to diagnose but if you have the resources, have a third party service center take a look at the phone. They may be able to identify a failing component that Samsung technician failed to check. If Samsung can’t find the cause of the problem, we doubt other independent technicians can but if the issue keeps on pestering you, you have to other choice but to ask for a replacement phone.

Problem #3: Galaxy S5 stuck in black screen after update was interrupted

Good evening. This morning, just before leaving home for work, I noticed that my phone, Samsung Galaxy S5, was installing some updates as it said “actualising Android.” I couldn’t afford having my phone unreachable at the time because I was also waiting for a call just then. I unplugged the phone from the charging cable and tried to turn it off. Removed the SIM card and put it into a different phone so I would be reachable by phone. The issue is that once I tried turning this Samsung mobile again, only the welcoming black screen with white letters saying “Samsung GALAXY S5” show and stays like that forever. It looks like the Android software is gone. I wish I had been asked to either do this actualization or not because I would have then managed to do it another time, when I wouldn’t need to be reachable by phone. This has been a very unexpected broke down of the phone and quite annoying.

How can I get out of that black screen and get the Android software back? How about my pictures, videos and documents, will they still remain in the phone’s memory? I can’t afford losing them. Please, help and guidance will be appreciated. — Evelyn

Solution: Hi Evelyn. Interrupting a device while it’s trying to install an update is one of the surest way to kill it. Whether the interruption is done intentionally or not, there’s always a big chance that your phone can get bricked. If you’re lucky, you may be able to boot the phone back to alternate mode so you can do follow-up troubleshooting. The troubleshooting steps may or may not allow you to recover your files. For example, if you can boot your phone to recovery mode and be able to fix the issue by wiping the cache partition, nothing will be lost (except the temporary files). The same is true if you are still able to boot your device to safe mode.

Below are the specific steps on how to boot your phone to other modes. Again, bear in mind that if your phone will only let you boot to download mode or to recovery mode, there’s a chance that you may not be able to recover your files. We hope all the best but if the phone remain stuck after trying the different steps, consider getting a new phone.

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.

Problem #4: Photos disappear in Galaxy S5 | Galaxy S5 loses photos taken by camera app

I’m in Iceland on vacation and since I have Virgin Mobile, I’m only connecting to WiFi and am using power converters/adapters to charge. My issue is with my photos. This morning, my phone refused to charge when connected to a charger (it’s charging now). I’m not sure if that’s related, because shortly after I used my phone to take pictures. The pictures wouldn’t appear in my Gallery but if I took a photo and pressed the last photo thumbnail in the camera, it would show all my photos. Now, however, it won’t show any of the photos I took today. My photos stored in my SD card and my photos from the rest of my trip and before appear, but again not the ones I took today. I also have apps on my SD card, and those are working. Please let me know if there is a way to recover the photos. — Breanna

Solution: Hi Breanna. File recovery in this case depends whether or not the said files are still in the phone somewhere, and if they are not corrupted. Photos and videos taken by the stock camera app are usually kept in a default folder that My Files app can open easily. Simply open My Files app and see if you can find your files in their default locations. If not, try to use Smart Switch to create a backup of your files and browse all folders. In order for Smart Switch to work, you need to install it in both your phone and your computer. If you haven’t used Smart Switch before, you can visit Samsung website to get it.

Problem #5: Sony headphone not working properly on Galaxy S5

Hi. I have a Galaxy S5, the Tracfone version, and I’ve got a pair of Sony MDR-x05 headphones, with volume control /microphone. When I plug in the headphones, I get the headphone icon in my notifications, but the volume control doesn’t work at all, and I don’t think the microphone works either. Strangely, from the headphone section, when I pull down from the top of the screen, even trying to place a call, the headphone icon disappears, and the audio switches to the phone speakers. Headphones then won’t work until I unplug and plug back in again. I thought it might be a trrs(?) issue, but I can’t seem to find anything on the compatibility of these headphones, or whether or not that would be an issue. And if it’s of any help, I use the Google now app launcher interface,  rather than the factory Samsung one. Thanks! — Justin

Solution: Hi Justin. We don’t know the specifications of the headphone you’re using so it’s possible that there may be a compatibility issue at play here. Kindly refer to the documentation of the device to see if it can work with a Galaxy S5 or not. Otherwise, try connecting it to another S5 to see if the issue is present too.

Problem #6: Galaxy S5 freezing and restarting after installing apps

Hello. I bought a Unlocked Samsung Galaxy S5 phone off a person on Craigslist. Originally the phone is from T-Mobile but i am using it with AT&T.

So I went home and did a factory reset on it.

I put in my micro SD card and SIM card and started using it. I downloaded some apps and that’s when it started doing the freezing and restarting. I then ran the phone on safe mode to see how it would do and It worked really good. I then went back on regular mode and deleted apps and still kept freezing and re-booting. I took out the micro SD card yesterday thinking that could be it but phone is still doing the same thing. Sometimes the phone shuts off and doesn’t want to start up again so i have to take the battery out for about 15-20 min before it starts working again. I was able to get it started again and i did another factory reset on it without the micro SD card and same issues. The phone got slow again, froze and shut off. Please help me! — Rudy

Solution: Hi Rudy. It’s interesting that you mention the phone working fine when it’s on safe mode. That means that one of the apps you install is causing the instability problem. Work on that by identifying what app is problematic and you should be okay. We suggest that you uninstall one app at a time so you can observe how the phone works afterwards. If the problem remains after you uninstall an app, continue the process for the rest of your apps until you’ve eliminated the problem. Don’t do this for “some” apps only. Make sure that you test all apps (expect for the pre-installed ones) if you want to fix the problem.

Problem #7: Galaxy S5 won’t charge using 2 power banks

Hi. I have an issue with my Samsung Galaxy S5. The phone will charge with both USB 2.0 and USB 3.0 cables, both the original cable and an “Amazon basic” replacement cable I bought. The issue is that the phone will not charge from a power bank. I have 2 different power banks. One is a Jackery 12,000 mAh Dual USB Power Bank, with one USB output rated at 5V/1A and the other rated at 5V/2.1A. I also have a Jackery Titan 20100 mAh Duel USB Power Bank, with both USB outputs rated at SmartFit 5V/3.4A. When I connect the phone to the power bank, using any of the cables I have that work fine when charging from the wall or car outlets, the phone doesn’t recognize the power bank and will not charge. Yet, when I use the same power bank on my son’s Galaxy S4, it charges fine. Any advice you can give me on getting the Galaxy S5 to recognize the power bank would be appreciated. Thanks. — Tom

Solution: Hi Tom. The Galaxy S5 should work with any power bank that has a similar output to your power banks. Our own S5 charges fine with at least two different powerbank brands (ASUS and Romoss). Both have outputs of DC 5.1V 2.4A. We tried replicating your issue by using official and unofficial USB cables and everything went fine so we can’t be sure where the problem lies. There may be an issue with your phone (probably on the software side), or that the two power banks your have are simply incompatible (we doubt this is the case though). There is no official word from Samsung regarding compatibility issues with portable chargers (power banks) so we have no reference where to look. We do know that there are others experiencing the same problem but we have don’t have enough data to identify a pattern. We will park this issue for now and will update this post once we have a good understanding about this problem.
