Problem #1:  Galaxy S6 keeps restarting on its own

Well i bought an S6 SM-G920F written on back cover and the same was on about device option of my mobile. After 4 months of use, one day when i was using it, it suddenly just hanged and no matter what i did it just did not restart after an hour. It just restarted and then started my problems.

First of all its soft keys stopped working. i thought it was a bug that’s causing it or a rogue app. i did a bit of Google about the apps but nothing. Then i soft reset it — nothing. Then i hard reset it but still nothing.

After 3 to 4 hours of Googling i found that one should change the firmware if a problem like this happen. believe me bro i have done everything that is present on internet before flashing it via Odin. When flashing, i downloaded Sm-G920F firmware  as it was mention on its backcover and its about device option via Odin.

By the way which i failed again and again i changed many updates from Sammobile and other websites for SM-G920F. After a week off failing to flash my device with every possible blog and options by Google i still failed, I realized early when i started flashing that in download mode the Product Name was written SM-G920P.

But as it was written in the backcover and about device that it was a SM-G920F, i relied on that but when i failed again and again i decided to download a SM-G920P version, which was a success flashing via Odin. so i thought after a week i did it at last my mobile was alive. After the flash my mobile’s softkeys still are not working.

Before that the device started to go in a bootloop which not only drained the battery but me as well after all that googling on internet day in day out. After draining it completely, which i read in a blog, i recharged it again and then when i started, it worked. it got out of the crazy bootloop. Now what i did is that i re-flashed it again with same firmware from another firmware. the device just keep going on the screen when going on the updating App screen. Now I’m completely blanked that what should i do to resolve it because i need my phone back and running, not a device which is restarting and going in bootloop…Need your help. I would be much appreciated for your reply brother…thanks. — Abdul

Solution: Hi Abdul. As we’ve been repeating in almost all materials we posted about this issue, if you’ve exhausted all software troubleshooting and solutions at your disposal, you can assume that the issue may be hardware-related, and thus beyond your ability to fix. There’s only so much that an end-user can do. The same is true even for Samsung or third party technicians. Not all issues are fixable at a user’s level so it’s time that you consider having the phone repaired or replaced. This may be a hard pill to swallow after doing all those things but this is the only resolution left for you.

Problem #2: Rare Galaxy S6 lockscreen/display error

Dear Sir/Madam. I have searched the forum and the internet but couldn’t find an explanation for the display error on my lock screen. I have had this problem for 3 days now. When I press the centre key on my phone to check the lock screen I see a twitch on the clock as if an application notification is going to show up even when there is no notification.

Similarly when there is a notification from any one of the applications, the notification moves down as if there is another notification and then it moves back up again. The problem is not causing me any problem with my phone but it is very annoying. I uninstalled the two applications I downloaded recently to see if they were causing the problem but the problem still exists.

I switched on my phone on the safe mode and I didn’t see this problem. Is this because of the applications I have been using since I got my phone? Or could it be a problem with the display settings of the phone itself?

Since the problem is on the lock screen, I cannot take a screenshot to attach to this message.

I look forward to hearing from you soon. — Eliz

Solution: Hi Eliz. If the issue does not occur when safe mode is enabled, that means that one of the third party apps or associated service is the cause. Because this bug may only be isolated to your device (we are not aware of similar reports from other Galaxy S6 users), the only thing that you can do is to uninstall apps until you have eliminated the problem. Keep in mind that there is no surgical way to fix bugs like this so you must invest time and effort in uninstalling and observing the phone until you removed the cause from the device.

Problem #3: Galaxy S6 won’t turn back on

S6 Edge crashed while browsing the other night (100% battery & was charging at the time), screen froze and wouldn’t do anything so i rebooted it using the power button and the volume down key. It went off, all good but it hasn’t come in since. I have read through all the forums online and the advice you guys have on website about holding different keys at the same time, still nothing absolutely dead. Although, I have tried plugging it into my computer, and when I hold down the power key my computer makes a noise to say it’s picked up USB device, so I click onto the connected devices menu on laptop and it has ‘exynos 7402’ as connected. but it says driver unavailable, and when I let go of power button the computer makes a noise to say something has been disconnected and the Exynos 7402 disappears.

I have no idea what’s going on but the phone must have some life in it if I’m managing to pick up something on laptop while power key is held continuously on the phone. But the phone shows no life at all, no lights, sounds, or vibrates… Dead!!

Please help…! Thanks. — Danny

Solution: Hi Danny. There had been some rare cases in the past that a bad power button results to an issue similar to yours. If you are unable to boot the phone to other modes by pressing different hardware button combinations, it’s a good idea that you have the phone checked by Samsung or a third party repair shop.

Problem #4: Galaxy S6 Edge Plus mobile data is not working

Hi. First, I would like to thank you for having this available. I truly hope you can help me fix this issue! My issue is Only Data related. when using Wi-Fi I have no issues! But when not on Wi-Fi my 4G data is useless. 80% of the time the arrows beside the 4G icon show only outgoing data.  

The Phone Info is:

T-Mobile Samsung Galaxy S6 Edge plus

 Model: SM-G928T

Android Version: 6.0.1

Baseband version: G928TUVU3DPG1

Kernel: 3.10.61-8479853

Build Number : MMB29K.G928TUVU3DPG1

The Following APN Settings Are Used Not by Choice but because it is the default APN and it is grayed out so you cannot delete it.

Name: T-Mobile US LTE , APN:, MMSC;, MCC:310, MNC:260 , APN Type :default,mms,supl , Apn protocol IPv6 Apn Roam IPv4.

I have data turned on under data usage, Data Roaming On, Network Mode: LTE/3G/2G (auto connect)

 Just a note I have added both APN settings available the and the, with all the required settings and that does not help.  I have tried a lot as you can see to fix myself before asking for help but i am officially stumped! the last thing i was thinking of trying is maybe flashing new radio? Any and all advice would be greatly appreciated! — Donald

Solution: Hi Donald. We want to make it clear, as our first point, that an issue like this can be only be effectively resolved by your network operator. That’s due to the fact that you are using and paying for their service so you are entitled to direct assistance from them. Mobile data issue like yours has a network and account aspects that only your carrier can see and fix. That puts them in the best position to offer opinion on this matter. For all we know, the reason for the problem may be related to your account’s billing status, or to current network problems affecting your area. Things like correct APN settings, network configuration information, account billing information can only be supplied by your carrier. Make sure that you contact them as soon as possible.

The things that you can do at your level is rather limited for this issue. The potential solutions that you can try include:

  • wiping the cache partition,
  • booting in safe mode, and
  • factory reset

Wiping the cache partition is a necessary first step in troubleshooting this problem as the operating system uses a system cache to load apps efficiently. Sometimes, the said cache, which is stored in the cache partition, gets corrupted. Refreshing it may work wonders in this case. Here’s how to do it:

  • 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.

If refreshing the system cache won’t do anything, you can also try to boot your S6 to safe mode. This will allow you to check if the problem is related to a bad third party application. If the mobile data issue won’t occur while the phone is in safe mode, that’s a confirmation of our hunch. Make sure that you observe the phone for 24 hours in safe mode in order to give you ample time. Here are the steps to boot your S6 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.

If the issue remains even while the phone is in safe mode, don’t hesitate to wipe the phone clean via factory reset. Remember, factory reset will delete everything so make sure that you create a back up of your personal data before you do it. Kindly refer to the steps below on how to do it.

  • 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 Vol 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 #5: Galaxy S6 camera won’t focus and takes ugly photos

Camera worked great then developed intermittent issues for no Given reason. Over time  the issues are happening more often and taking longer to resolve and focus. Upon opening the camera app the picture on the screen has a jello like appearance/the image looks like its underwater. this lasts 10 seconds before it attempts to focus. Anytime the camera tries to focus it makes a vibrating motor sound (the noise is perfectly in sync with the phone trying to focus). When this happens you have to close the camera app to force it to stop. when you reopen the camera app the problem is resolved. (80% of the time you have to open and close the camera app multiple times before it stops and finally focuses correctly).

Once the phone has finally focused and you take a picture, the photo is poor quality and the colors aren’t as bright and vivid as used to be. My wife has the S6, she took a picture with her phone on pro mode and one on auto mode. She then took 2 pictures with my camera of the exact same scenery, one on pro mode the other on auto mode. My auto mode picture was the worst, poor colors and slightly grainy. Side by side her auto mode picture looked exactly like my pro mode photo. Colors were brighter, good but the image was not sharp and defined. Her pro mode photo has gorgeous detail, vivid colors that just “pop”.

When I first got my phone my pictures on pro mode were substantially better than hers. I have reset the camera to factory settings with no change. I also tried a factory reset on my phone but that did not help.  Any advise or suggestions would be greatly appreciated! Please feel free to email me with any questions. My phone has never been exposed to water, harsh conditions,  and never been dropped. Please help. Thank you. — Shane

Solution: Hi Shane. The only effective solution that we know in fixing camera-related issues is factory reset. The said solution works if the problem is due to bad software, obviously. That factory reset did not change anything in your case is a clear sign that your phone’s camera may be malfunctioning. Unfortunately, the only way to fix it is to have it replaced. Contact Samsung or your carrier so they can arrange a repair or a replacement for you.
