S6 Randomly Shuts Down Fails to Reboot

Problem: Hi! I have had my Samsung Galaxy S6 for about six months now with near to no issues. Recently, however, the device will randomly shut down and attempt, (and fail), to reboot, repeating the boot screen and shutting off. Sometimes it will restore itself, and other times, I’ll have to power it down and back up via maintenance boot mode. It seems to have no connection to how long it has been used for or any specific app being run, and I already factory reset the device with continued issue. It will also boot down while on a charger. Could this possibly be an issue with the battery? Thank you for your help!

Solution: If you have already performed a factory reset then we can set aside any software related causes right now. You mentioned that the phone also reboots even when it is connected to its charger. There’s a possibility that the problem could be caused by a fault battery or it could also be caused by a power IC that isn’t working. You will have to bring the phone to a service center and have it checked if this is the case.

S6 Fast Charging Stopped

Problem: hello i own a galaxy S6 it was charging fine until recently a few days a ago the fast charging stopped however the cable charging kept working just fine yesterday it died and i tried a friends charger but it said it would take hours to charge so i gave it back when i got back home i used the normal charger it started charging and then when i took it it was like 30% and that started draining abnormally fast and when i finally decided to charge it again it would like charge for a minute then stopped i used different chargers cables used the computer nothing the weird thing is when i close it and put the charger it charges for a bit then when i open it the screen suddenly turns black with a small x in the left down corner and the screen goes back to normal fast but the phone stopped charging i really hope u can help me out

Solution: For this particular issue you should start by cleaning the charging port of your phone. Use a can of compressed air when cleaning the port making sure that any dirt or debris is removed. Once this is done try charging your phone again. If it still doesn’t charge then try using different charging cords and wall chargers.

Should the issue still persist then I suggest that you bring your phone to a service center and have it checked as this might already be a hardware related problem.

S6 Charging Percentage Keeps Changing

Problem: This is the first time I’ve noticed this and it is so odd. I’m not even sure about blaming the cable anymore. So I left my phone to charge at 50% on fast charging and came back to it after 1 and a half hours later. It had charged to 89% only, which I suspect was because of the vibration the charger moved from the position it charges in ( has to be angled because the cable is bad). So I’m using my phone while it charges, it kept saying ‘approximately 1 minute to fully charged’ while on 89%. Kept doing that till it got to 90% which was 10mins later and then it said approximately 7mins to fully charged then said a minute again. But then 30mins later I look at the status it changed under 30 seconds to 95% and then 97% and then 100% in less than 10 seconds. I’m getting all happy then it finally charged fully, and the all of a sudden it went back to 88% again saying ‘approximately 1 min to fully charged. Why is this?

Solution: The first thing that you should do in this particular case is to check if the charger is causing the problem by following the steps listed below.

  • Clean the charging port of your phone using a can of compressed air. Make sure any dirt or debris gets removed.
  • Try using a different charging cord when charging the phone.
  • Try using a different wall charger when charging the phone.

Once you have eliminated the charger as a possible cause to the problem it’s time to concentrate on the phone itself. We also have to take into consideration that this might be caused by a bad charging port since you mentioned that the charging cord has to be angled a certain way in order for the phone to charge but let’s set this aside first.

On the phone side try checking first if a glitch in the phone software is causing this problem by performing the troubleshooting steps listed below.

  • Try charging the phone when it is started in Safe Mode. Does the issue still occur in this mode? If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Start the phone in recovery mode then wipe its cache partition.
  • Backup your phone data then do a factory reset.

If the problem still occurs even after performing the steps listed above then you should bring your phone to a service center and have it checked. It’s possible that this could already be caused by a faulty charging port.

S6 No Longer Fast Charges After Installing Marshmallow

Problem: After installing the latest update 6.0.1 my phone will no longer fast charge.  I have done a factory reset and problem persists.  The phone will charge using a USB port on a PC but when it is inserted the PC sends a message that the device malfunctioned. In addition I cannot get the bluetooth to sync up with my vehicle (2016 Toyota 4Runner).  Phone keeps telling me to insert a 6 digit pass code but will not allow me to get to a keypad to insert the code.  The phone sends messages every minute or so with a new pass code.

Solution: Since you already performed a factory reset then we can eliminate a software glitch that could be causing this problem. You need to try cleaning the charging port of your phone using a can of compressed air. Make sure that any dirt or debris that gets stuck in this port is removed. You should also try using different charging cords and wall chargers to verify if your current charger is causing the problem. Should the issue persist then I suggest that you bring your phone to a service center and have it checked.

S6 Phone Screen Stopped Working

Problem: Phone’s screen stopped turning on yesterday. Was working fine, and then was unresponsive the next time i attempted to turn on the screen (hitting power or home). Originally it was showing the blue indicator light every five seconds. After trying various button combos, that light eventually disappeared, but nothing ever appeared on the screen. When attempting to plug in to charge, it doesn’t vibrate to indicate its been plugged in, and now other light comes on. Have others been experiencing this problem? The phone has never done anything to void a warranty, and never been physically damaged or dropped.

Solution: What you should do first in this case is to charge your phone for at least 20 minutes. Make sure that there is a charging indicator on the device. This way we will know that the phone has some power when we do the troubleshooting.

To fix this problem what you should do first is to simulate a battery pull. You do this by pressing and holding both the power button and the volume down button for at least 10 seconds. Your phone should restart after this.

If the issue remains then try to check if you are able to access the recovery mode. If you are able to access this mode then I recommend that you do a factory reset. Take note that the reset will erase your phone data.

Should the problem still persist then I recommend that you bring your phone to a service center and have it checked.

S6 Screen Turns On Then Immediately Turns Off

Problem: A couple times a week when I try to turn on my phone, it doesn’t matter what button I use, the button on the side or the home button, the screen will turn on and immediately turn off. It would take 5 to 10 times for the screen to actually stay on so I can unlock my phone and do what I need to do. What could it be causing this issue?

Related Problem: Hi, I’ve been having this problem on and off again over the last week or so. I go to check my phone and it is turned off. No biggie. Today, I dropped my phone onto my backpack about two feet. After about 10 minutes I went back to check my phone and it was off. But, when I plugged my  phone up it was on about 94% charge. I cut it on and the lock screen came up but only for about 30 seconds. Please help ASAP

Solution: You could try checking first if an app you installed in your phone is causing the problem by starting the phone in Safe Mode then checking if the issue occurs in this mode. If it doesn’t then the problem is most likely caused by an app you downloaded. Find out what app this is and uninstall it.

If the issue occurs in Safe Mode then you should consider performing a factory reset. Make sure to backup your phone data before doing the reset.

If the above steps fail to fix the problem then you should bring your phone to a service center and have it checked.
