Problem 1: Galaxy S6 won’t charge, won’t turn on, keeps rebooting by itself
It started by randomly restarting on its own. Then it started randomly powering off on its own. I would have to push power button to turn it back on. Then it got to where i would have to plug it in to a charger to get it to power back on. Then it got to where it had to be plugged into a Fast Charger in order for it to power back on. And sometimes will shut off as soon as unplugged. Sometimes when plugged into a charger, it will try to repeatedly power on by itself. Now you might get it to power on while plugged in if you are lucky.
I’ve tried everything- soft reset, hard reset, factory reset. I’ve even taken it apart and unplugged battery and anything else i could get to that had a plug-in. I didn’t see anything burnt on green board. Do you think i just need a new battery, or is it something more serious? I am not positive on which Android version it is using as i can’t get it to come on at the moment. — Jessica
Solution: Hi Jessica. Since you’ve already dismantled the phone and tried all software solutions without any positive result, the cause is most probably beyond the battery. Another common issue that shows symptoms like the one you’re getting is a bad power management integrated circuit (IC). This is the chip that usually fails first if the phone has been plugged in to the charger during high voltage power surge, or when there’s tiny power surges that happens for a long duration. The power IC is the chip responsible in regulating power coming from the battery and into other chips in the motherboard. If it doesn’t work properly, it can sometimes result to random reboot issue. In its worst case, a phone won’t even turn on at all. Checking the status of a power IC and other relevant components require a particular skill and special tools so we recommend that you let a professional do it for you. Only then will you know if a simple repair can fix the problem, or if a phone replacement is a more economical way to allow to you have a working device.
Problem 2: Galaxy S6 keeps restarting every few seconds
Hello. my phone keeps restarting on me. It will turn on and off on its own letting me use it for a few seconds, when it turns on until it restarts again. I’ve tried safe mode, wiping the cache, as well as putting the phone in AMOLED Photo mode, and nothing has worked. I really need this problem to stop because I am a songwriter and have a couple years of important notes on a particular app that I’m not sure could be recovered through the hard drive. I’m going to be getting a new phone soon anyway but need this one for the purpose of accessing these notes. Thank you. — Emery
Solution: Hi Emery. If you can’t make the random reboot problem stop by booting to safe mode, that only eliminates one of the few possible causes which is third party apps. Other potential reasons for your problem can be:
- a software glitch
- bad battery
- or other motherboard-related issues like the one we briefly discuss above (malfunctioning power IC)
To check if it’s a software glitch, you must try a factory reset, which is out of the question at this time since you intend to recover important data. That leaves you without much choice. To see if it’s just a battery problem, we highly recommend that you let a professional replace it for you. If a new battery won’t help either, you’re out of luck.
Some users were known to have temporarily fixed their random reboot issues by keeping their phone connected to a charger. If you haven’t tried that, consider connecting it to a powered USB port of a computer. If your phone will stay powered on, you can then move your data over to said computer.
Problem 3: Galaxy S6 edge won’t turn on
Dear Team. I have a problem with my S6 edge since 2 days ago. I have left the phone on for the night, with a full battery. When i woke up, the phone was off with a blue LED. I plugged the phone in and started charging. When the battery charge was at 40%, i plugged the phone out and booted up. Everything was ok, but the battery showed 0%. After that, i connected it again and it showed me 0% during the charge. [Phone was off] I did it a couple of times, just to see if the battery really died or it just was a minor issue in Android. Well, unfortunately the problem still occurs. Just to acknowledge, sometimes the phone hangs very bad and the soft keys don’t work properly, even after a Smart Switch update from a custom ROM. I really want to get help if i can still save my phone or do i have to change the battery and so on. Please, respond quickly and thanks. — Kamil-kus12
Solution: Hi Kamil-kus12. We want to make it clear to you and to rest of our community members that if the phone fails to boot up, either in normal mode or in other modes (Recovery, Download, or Safe Mode), the cause of the problem is almost always bad hardware. Hardware-related issues like a malfunctioning battery or power IC can lead to the problem you’re experiencing. We strongly encourage you to try first all software solutions especially factory reset. If the problem remains, or the phone remains dead, you can assume that a hardware issue is at play. As mentioned above, you want to let a trained professional check the hardware for you.
We also suggest that you try to see if you can power on the phone to alternate modes. Here are the steps on how to do each of them:
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 logo 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 logo 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 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: Cannot create a backup of SMS from Galaxy S6
Hi. A few weeks ago I used an app that I’ve used in the past to email my texts to my email account. I downloaded the messages, and while I was looking through them I noticed there were a lot missing. Hoping to find another program/app to view my messages and print them from my computer, I began my search. I’ve tried different messaging apps, backup apps, backup and restore apps, different backup and restore software, I’ve tried mobiledit, backuptrans, and a few other types of software that’s for recovering text messages, and another that’s supposed to be able to extract your information by rooting, then unrooting your phone. None of these have worked. It seems that the only place I am able to view all of my text messages is from my default app.
I’ve been in contact with a group of customer service reps from one of the apps that I tried. They couldn’t figure out why their app was unable to show all of my messages either. They said that “my default messaging app is not storing my messages correctly.” I’m trying to do this for court. I’m not a lawyer, this is for a personal family court matter, which is making me extremely desperate to find out and fix whatever is wrong. I was nervous to see that messages were missing, but hearing that the messages are not storing correctly, I’m extremely freaked out! I’m assuming that unless I keep this phone forever, I will eventually lose those messages..since there’s no way to save all of the messages. I’m hoping you might be able to help me..please! I truly appreciate any information you might be able to pass on to me. — Jmieann116
Solution: Hi Jmieann116. If you are positive that ALL of these messages are stored in the default messaging app, we suggest that you try Samsung’s Smart Switch app to back your messages up. We recommend that you use Smart Switch to store everything in a computer so you can simply restore your messages and other settings like apps to another Samsung device in the future.
Keep in mind that some of your SMS may be kept in your SIM card’s inbox (if you’re in a GSM network) so make sure to check that too. A SIM card’s inbox is very limited though so it can only hold a handful of messages at a time.
Should you need important SMS for legal purposes, consider reaching out to your carrier to see if they can give you copies of those missing messages in your phone.
Problem 5: Galaxy S6 loses battery power fast, charges very slowly
So, I’ve been having this issue with the Samsung Galaxy S6 for a long time. Here’s how it goes: it takes a very long time to charge, around 6 hours to a full charge. That is with the original charger. I tried several different cords and wall adapters, however none helped me fix the issue. I cleaned the charging port very carefully, but it did not help either. Also, I’m having issues with battery life. It does not last 2 hours of regular use with the screen on. I tried doing software troubleshooting but it didn’t work. So my phone takes huge amounts of time to charge up and the battery discharges at an unreasonable quick time. I hope you guys can help me figure out what’s the main issue and then I can take it to a repair place. They could not tell me what the problem was, so I couldn’t manage to fix it yet. Thanks a lot in advance. — Marco
Solution: Hi Marco. Android troubleshooting is simple — if you’ve already exhausted the usual software solutions like observing the phone in safe mode, installation of app or Android updates, and factory reset, the most likely cause must be hardware-related. Knowing the main cause of the problem though is difficult unless the hardware is physically checked. We can’t possibly know what the problem is given how little information we’re getting from you. It’s not your fault though. Even if you can provide more details, we doubt we’ll come close to identifying the culprit still. As mentioned, only after the hardware is checked physically will you get more information about the problem. It may be a battery issue, or something else in the motherboard.
Problem 6: Galaxy S6 from Korea won’t connect to Optus network in Australia
Hi. I purchased a used Samsung S6 over the Internet. It was sent from Asia (possibly South Korea). It works great except I cannot connect to 4G (my provider is Optus Australia). My wife has the same phone and provider yet has no issues. One thing I have noticed is when I check my mobile network settings, and select ‘network mode’ I have only 2 options. The first is “Use LTE when available” and the second is “3G only”. I do not have the 4G option similarly to my wife. Could this be because the phone is not compatible with the 4G bandwidth – as suggested by my local Optus in store customer service rep? Any help would be greatly appreciated before I throw this phone in the bin! Cheers. — Damo
Solution: Hi Damo. South Korean networks use CDMA technology so if you’re correct and the phone came from one of the networks there, there may be a compatibility issue with your current network’s protocol. If we are not mistaken, Optus Australia uses GSM protocol, which can be the main reason for the absence of 4G network as an option.
Another possible reason may be hardware incompatibility. This means that the operating frequency (or radio) that the device supports is different from the frequencies Optus is using. Try to do some research about your phone by searching for the frequencies it supports. Make sure to search for information about it using the phone model usually seen on the back cover, or under Settings>About device.
If you can’t seem to find your way in your research, contact your carrier to see what are the possible causes to the problem. Be sure to mention that the phone may not be compatible so they can look at this angle.
Problem 7: Galaxy S6 overheating and draining battery fast
Samsung S6 duos overheating and draining battery. I’ve tried rebooting, uninstalling several apps, wiping cache. Running in airplane mode has helped so far so the phone stays up without draining too fast but still drains at a faster pace than usual. Phone has been running fine with 2 SIM cards from Nigeria. Trouble started when i came to the US and switched one out for a US SIM card. Now the same happens when i switch back. I’ve since installed an upgrade while in airplane mode as well but no luck. Battery does not last an hour and phone gets too hot to touch! On the power button side. Please help! — Tjsmart
Solution: Hi Tjsmart. Do a factory reset and see what happens. This is an important first step for this case so you’ll know if the problems (battery drain and overheating) are due to apps and/or software, or if there’s bad hardware, possibly bad battery, involved. If the problem remains after a factory reset and without apps and updates installed, you can bet hardware malfunction is to blame.
Below are the steps on how to factory reset your S6:
- Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
- Turn off your Samsung Galaxy S6 Edge.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
Problem 8: Galaxy S6 edge won’t unlock after it was set to power saving mode
Hi there. I have put my S6 edge in power saving mode two days ago and since then it does not take my lock screen password, nor does it give me the option of finger print password. I have had the same password for 2 years now, so I am sure it is not because of a wrong password typo thing. I read multiple times that after typing in wrong password it eventually will give you the option to unlock it with a google account. However, it only continually says try in 29 sec again. I already tried rebooting in safe mode, that did not do the trick either. Do you have a suggestion on how to be able to unlock it with a google account or any other suggestions? I unfortunately do not have a samsung account. I hate to do a factory reset since I of course, did not save any data. Thank you so much PS: IM NOT SURE WHAT ANDROID VERSION I HAVE ON MY PHONE. — Ramona
Solution: Hi Ramona. The only other way to gain access to your phone without using a Google account or Android Device Manager (ADM) is factory reset.
Keep in mind though that if you did register a Google account in this phone before, you’ll also be prompted to enter your Google account credentials by Factory Reset Protection. If you can’t enter the correct Google username and password after that, you won’t be able to factory reset the phone at all.
