Problem #1: Galaxy S6 edge audio stops in the middle of a song

Good day, My Samsung S6 edge (SM- G925F) has recently started having audio issues. It started about a month ago and the sound will randomly cuts off in the middle of a song. It does this with music, audio and video. The audio will sometimes keep playing but there will be no sound coming from the speaker or headphones if I’m using them. Other times it will just stop and freeze. The only thing that helps is rebooting my phone either using the normal power button or rebooting it by using the volume down and power key at the same time. This will temporarily fix the problem until I play another song. The audio does this whether I’m listening to music via Google Music or the Music app on my phone. I have tried everything including factory reseting my device and updating to the latest Android software (6.0.1) but the problem persists. Thank you for your help. Regards. — Siphokazi        

Solution: Hi Siphokazi. If factory reset did not help, the cause of the problem must be the same app you reinstalled afterwards. Try to restart the phone to safe mode and observe how the phone behaves when playing music and videos for 24 at least 24 hours. This observation time should be more than enough to tell you if our hunch is correct or not. Safe mode blocks third party apps and services so if your phone plays audio properly, that’s a clear sign that one of your apps is the culprit. Follow these steps on how to boot 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.

Alternatively, you can do the reverse and do another round of factory reset and observe it in 24 hours. Make sure that you don’t install anything during this time.

Problem #2: Galaxy S6 showing black screen with “x” at the bottom when charging

My phone’s charging has been completely messed up since yesterday and I can’t figure out why. I was in class and I decided to charge my phone and hooked it up to a multiple outlet extension cord. This extension cord had a desktop computer connected plus my computer charger. When I charged it however the phone sort of glitched. I got this black screen with an “x” on the bottom right then bottom left corners and the charging symbol disappeared. So I disconnected my phone from the charger. Then I try again. It works but as soon as I got on to text someone that black screen appeared and again the charging symbol was gone. I reset my phone and I charge it again. It’s fine for a few minutes but then it happens again, black screen with an “x” and the charging symbol is nowhere to be found. I clear my cache when going on safe mode. Then reset. Charge again, same thing happens.

Another thing to do note is the battery level of my phone. It changed dramatically. At one moment it said it was at 37% (or something like that) then it says it is at 14% when I reset it. In my battery history it showed a spike in battery (to 37%) but then a lull soon after (14%). I give up charging it for that class. I go and try to charge the phone in my dorm and that same problem appears when I charged it back in class except I am using a wall outlet instead of a extension cord.

So I decide to let the phone die and go to 0%. It does that and I charge it while it’s off. It works and it’s charged to 100%. I thought for the most part the problem was solved. Just charge my phone off while I can figure out why the “glitch” was happening to my phone. So it’s 2 am and I get ready for bed and my phone is at 1%. It dies again and I charge it thinking that it would charge. The next morning I realize that the phone didn’t charge at all. I disconnect the USB and I reconnect it. I get the screen to tell me it’s charging with full brightness then it dulls and goes to black again. I turn on my phone and for the few seconds I had it I saw that my phone was at 0%. I straight up can’t even charge it anymore. I used the wall outlet first then tried just hooking it up to my computer, didn’t work either. For whatever reason my phone just doesn’t want to charge anymore. Any reason why? Thanks in advance if you can answer this. — Sebastian

Solution: Hi Sebastian. We think the problem lies on the charging port. It may be damaged, or there may be a bent pin or dirt that prevents the phone from charging properly. Try to inspect the charging port with some form of magnification so you can check if there’s anything that looks out of place in there. If you can’t do that, consider doing the basic software troubleshooting like wiping the cache partition and factory reset. If these software troubleshooting won’t work, have the phone’s hardware checked.

For reference, here are the steps on how to wipe the cache partition and how to perform a factory reset:

Wipe the cache partition

  • 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.

Perform a factory reset

  • 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 #3: Galaxy S6 overheating and won’t turn on

Hello! My name is Andrew Basic. I was checking out your page about how to fix a Galaxy S6 that shut off randomly and couldn’t find any solutions that matched my problem. I bought my phone a little bit over a year ago and it always stays inside of an Otter box that I purchased with the phone. The only time I take it out of the case is once every two months or so just to clean the case and then it goes right back on. The phone still looks brand new when it’s out of the case. No damage that I’m aware of.

I charged my phone at work today and the battery was at roughly 85% when I left for home. I called my parents on my way and mid conversation my phone randomly shut off and would not turn back on. I attempted charging it (not with the original cable because it broke) and it did not respond, even when left for 15 minutes. I also attempted charging it with a wireless charger. The charger light came on when I placed the phone onto it, but the phone itself again did not respond. I did notice that the middle of the phone is warm on the front and back (like its overheated somehow). I figured I would try and reach out to you guys before I brought the phone into Verizon and they told me that they have no idea what’s going on, lol. Thanks! — Andrew

Solution: Hi Andrew. If you’re positive that your phone has not suffered any physical or water damage, you should start checking if software is to blame by doing all basic troubleshooting that we usually provide. These troubleshooting steps include:

  • wiping the cache partition
  • observing in safe mode
  • Installing all apps and system updates
  • doing a factory reset, and
  • flashing (recommended if you rooted or installed custom ROM) stock firmware.

If these troubleshooting steps won’t help fix the issue, or if the phone remains unresponsive, you should do one more thing which is to try and boot it to other modes. Bear in mind that you can’t do software troubleshooting in an unresponsive or unbootable phone. If you can boot the phone to an alternate mode, only then can do the follow up troubleshooting allowed by a particular boot mode. Here are the steps on how to boot to other modes and the follow up things that you can do:

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.

It’s interesting to note that you mentioned overheating as the possible reason for the problem. If a phone is overheating, it will shut down by itself but everything should be back to normal after you let it cool off for an hour or two. If that’s not happening, the appearance of overheating may just be an indicator of something deeper. Unfortunately, there’s no way to know what that hardware issue might be. If you suspect that hardware is to blame, send the phone to Samsung or to an independent service center for repair.

Problem 4: Galaxy S6 freezing and rebooting by itself | Galaxy S6 keeps showing pink LED light

Hi, just wondered if I might run this one past you.

I have the above ‘phone which am happy with but for a niggly issue which happens intermittently. Without warning it freezes and shines a very bright pink light where the blue notification light normally shows. It then switches itself off then on repeatedly and can then keep freezing. Recently I just had to leave it on all night not able to switch it off. While this is happening the ‘phone gets very hot even through the case. I seem to remember it first started after I did a software update but can’t be 100% sure on that. There is no pattern as when it happens, i.e., using any particular app but sometimes I feel it can occur if I’m asking the phone to do too much after switching it on, if that makes sense. I’ve searched online but can’t find anyone else who’s had a similar problem.

Any thoughts welcome. Regards. — Rob   

Solution: Hi Rob. The usual LED light indicators in any Samsung phone should be the following:


– Pulsing: the device is turning on or off.

– Blinking: there is an unread notification (missed call, message etc) or during voice recording.


– Glowing: connected to a charger and charging.

– Blinking: connected to a charger but not charging, or when low on battery.


-Glowing: connected to a charger and fully charged.

-Blinking: fully charged.

The pink LED light may or may not be related to the freezing and random reboot issue you’re experiencing. Other colors outside blue, red, and green may be due to an application that includes LED notifications. Try booting the phone to safe mode and observe it for at least 24 hours to see the difference. If the phone works normally while it’s in safe mode, that’s proof that one of the installed apps is to blame.

Bear in mind that freezing and random reboot issue can be caused by bad hardware. If the basic software troubleshooting like the ones mentioned above won’t work, have the phone repaired or replaced.

Problem #5: Galaxy S6 stuck in Samsung logo screen

So one morning I wake up and my Samsung Galaxy S6 is off and I tried to switch it on and it doesn’t wanna switch on. I put it on the charger and it shows it’s on 80%. Then I switched it on and it worked and it was switching on and off for the whole duration of the day until it could not switch on unless it’s on the charger. All this happened in a day then the next day I did a hard reset and it only worked for an day and it started again. I then replaced the battery with a new one but the problem continued. now it won’t even switch on. It will just show it’s charging and I switch it on and it gets stuck at Samsung logo and restarts…I can’t even do factory reset anymore. please help. — Dudley

Solution: Hi Dudley. Like what we tell Andrew above, you can only do troubleshooting if the phone is booted normally or to other modes. If it’s stuck in the Samsung logo screen and can no longer go to Recovery mode, that’s a sign that there may be a motherboard failure. Send the phone in to Samsung for repair or replacement.

Problem #6: Galaxy S6 cannot connect to cellular network

Hi. On a trip from Sweden to Denmark by ferry, I switched off mobile internet and wifi so that i don’t connect to the expensive maritime version. After that Wifi is the only thing that works. No calling, no texting, mobile connection only works sporadically on “H+” while we normally have 4G at most places here. We have talked to the operator; they see no problems. We have switched to an old Galaxy S3 mini and that it works fine apart from maybe that the mobile connection is the same shit, but that might be due to the phone. We checked all setting we could find, we restarted a million times, we googled all kinds of solutions, nothing we find works. HELP! — Caecilie

Solution: Hi Caecilie. If the same problem happens to a second phone, that cannot be a phone issue. It’s either a network service problem (signal may be intermittent), or that there’s a problem with your account. Either way, the only ones who can help you is your wireless carrier. If you’re using a roaming feature, make sure to report the issue to your wireless carrier in your country so they can advise you if their partner carrier in another place is having network issues where you’re located.

There’s really nothing much any third party technicians like us can do for you. You must work with the service provider where you’re at, or to your original carrier in your home country.
