Galaxy S6 fails to boot normally after a failed update, other issues

S6

As you may have already known, updates can sometimes cause problems instead instead of fixing some. That’s because there’s simply too many variables that developers cannot deal all at once. The interplay of operating system and apps can sometimes lead to conflicts that developers may not have anticipated. We hope that this post can help those looking for resolutions to their post-update issues.

Problem #1: Galaxy S6 making static noises when playing music loudly

Hi Droid Guy! So I have had my S6 since about July or August of 2016. I bought it new from eBay, never used and never had an issue with it up until about 2 months ago when it began making static noises when I turned my phone on and when I played music out loud.

I assumed it was my back speaker and went to get it fixed at a cellphone repair shop but even after they fixed it, the sound continued. I kept the speaker replacement as the other speaker had issues anyhow with sound. The people at the shop told me it might be a motherboard issue but did not really ask if I wanted that inspected. I am not sure what to do with my phone as it is in great condition and never out of its case. The sound does not occur during phone calls but is rather loud and bothersome everytime I turn on my phone and unlock my screen. Hope you can help!

Thank you. — K.Mata

Solution: Hi K.Mata. If static noise only occurs in certain conditions like when playing a sound, the cause may be app- or firmware-related.

Restart the phone in safe mode

The first thing that you want to do is to see if an installed third party app is to blame by booting the phone in safe mode. While in this mode, your phone will prevent third party apps from loading. Here’s how it’s done:

  • 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 fails to occur while safe mode is enabled, that’s an indication that one of your third party apps is the reason. Unfortunately, there’s no way to pinpoint the offending app. You must uninstall your apps until the issue has been eliminated.

Restore phone settings to default via factory reset

Another good way to fix software problems is factory reset. It does not only eliminate potential glitches but also resets all app and OS settings to default. It’s a proven solution for all things software do be sure to do it. Don’t forget to backup your files before you proceed. For reference, here are the steps 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 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.

And just to double check if one of your installed apps is to blame, make sure to observe the phone for some time after a factory reset without installing any app.

If static noises remain after a factory reset, you can safely assume that there is a hardware problem behind the trouble. Have the phone checked for hardware errors.

Problem #2: Sprint Galaxy S6 phone’s SMS are received by another member of the Family account

I updated my phone recently and I have had an issue with my texting ever since. Whenever I have a group message, I can receive texts but when I send a message, the people in my group receive it from a different number. That number is actually my mother’s. We are on a family plan with Sprint, that is really the only connection our phones have.

I talked to Sprint and they thought that my Google account might be on her phone. It is not.

We also checked third party messaging apps, such as Viber and WhatsApp. Nothing there either.

This problem also happens when I send and receive pictures. When either of these things happen (group text or picture sent), the replies from my friends go to my mom’s phone. Sprint says it’s not a network problem, I don’t know what to do. I just read that others are having problems with messaging after the update as well. Any help would be greatly appreciated! — Marvin

Solution: Hi Marvin. This issue can be fixed by the account owner, who is probably your mom. If she is the paying for the main Sprint account and that your phone is one of extensions under that account, she can do a lot of things to control how individual lines send and receive text messages. As an account owner, she can do the following things when she logs into her Sprint.com account:

  • Add, revoke or update user access to your account
  • Access online service tools, depending on the services your plan includes
  • Block or allow voice calls, texting, web access and data
  • Change your plan
  • Add a phone
  • Pay and update your bill
  • See minutes used
  • Check upgrade eligibility status
  • Post to the Sprint Community forum

As far as sending and receiving of text is concerned, an account owner can block incoming or outgoing messages on phones under the main account. Kindly ask your mom (or anyone who owns the main account) to log in to his/her My Sprint account and follow the instructions in this link to fix the problem.

Problem #3: Galaxy S6 Edge keeps rebooting by itself

I bought this Galaxy S6 Edge G925F from an online sales person and its seemed to be alright for a day or 2 then it had a quick reboot which didn’t close my used apps. The Samsung logo came up for a couple of seconds then showed by lock screen and all my apps used showed up in the recent keys. It didn’t really bother me then when it happened like 3 times a day but now it happens so frequently that sometimes it becomes so annoying using the phone. 

I’ve booted to safe mode, uninstalled apps, done a factory reset several times, even rooted it. Still no change.

I’ve flashed it with a new Marshmallow firmware from Sammobile and still no change. Now I’m wondering if it’s hardware or software and can it even be fixed? Thanks for the help. — Raphael

Solution: Hi Raphael. If doing all software troubleshooting steps did not change anything at all, you can say that you have a hardware problem at hand. As you can see, a user can only do so much when it comes to fixing a software issue. If the random reboot and accompanying issues happen even after a factory reset and without any apps installed, that’s a clear sign that there’s no software issue involved. If the phone is still covered by a repair or replacement warranty, we suggest that you use right away to resolve the issue.

Problem #4: How to save files from a Galaxy S6 that won’t boot normally

Thanks for helping. I have a Samsung S6, worked fine until yesterday. When I was talking on it while on speakerphone and I moved my hand quickly toward my head and the phone went flying through the air and landed on its protective cover but hard onto a wood floor. 

Since then it get hung up on the boot stage where on the screen it says the word SAMSUNG. It pauses there where the SAMSUNG pulses from clear font to more fuzzy font a repeating this pulse over and over. I have never backed up the phone, and have over 1000 photos and video on it. I would like to keep all of that data and photos, etc. somehow before I do a full reboot which may wipe it all out.

It seems the shock of the impact of hitting the floor caused this issue.  I have never had this happen before.

Is there anyway I can save the photos and video off to a different data storage source before wiping the phone and doing a reset?  Do I just need to let the phone sit for a few weeks?

Thanks. — Tom

Solution: Hi Tom. The only way to save data from your phone  is by connecting it to a computer via USB. If a computer still detects and recognizes your phone with a good working storage device, file transfer should be fine. If a computer won’t detect the device, you’re out of luck.

Problem #5:  “System UI has stopped” error on Galaxy S6

Hello there! I accidentally came upon your website and was rather happy that you welcomed emails regarding phone problems. I have just bought this phone last month, and it was brand new, from a legitimate Samsung store. Nevertheless, there has been several problems that keep occurring on a daily basis when I use it:

  1. a) Sometimes when you turn on the phone the lock screen/clock doesn’t show (I have a number lock). If you press the places where the numbers are and press ‘OK’, I can still access my phone but then it is rather annoying.
  2. b) “System UI has stopped” error. This message keeps popping up randomly after the phone doesn’t respond.
  3. c) Sometimes the volume doesn’t work properly, like when I turn up the volume it doesn’t become louder and vice versa. It only works if I restart the phone.

I am quite distressed as this phone is brand new and it already has so many problems. I would be really glad if you can provide any sort of assistance.

With thanks. — Xiuwei

Solution: Hi Xiuwei. Your concerns appear to be caused by bad software or app. First of all, make sure that  apps and operating system are updated. Out-of-date apps can create conflicts with other apps or operating system so making sure that they receive the latest available update may be necessary to fix some bugs. If the problems remain despite having made sure that everything is up-to-date, consider wiping the cache partition.

For minor firmware-related issues brought by apps and firmware updates, wiping the cache partition often does the trick. It’s because this procedure will literally delete all cached files in the cache partition, which will force the system to create new ones during the next boot up.

This procedure is also very helpful in fixing issues like random reboots, boot loop, stuck during boot up and random freezes after updates. Here’s how you wipe the cache partition on your S6:

  • 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.

Wiping the system cache (cache partition) will only work if there’s an app-specific issue. It won’t fix glitches that may be related to firmware though. You have to do a factory reset (steps provided above) to reset everything back to defaults. As mentioned above, make sure to observe the phone for some time before you install apps so you can see if something changed.

Problem #6: Galaxy S6 fails to boot normally after a failed update

My S6 asked for an update two days ago, I ignored it. Today it asked again, and I conceded. But the update failed by it was “interrupted”. Don’t know how or why, be I didn’t receive a text or call at the time. Just now my phone was low on charge so I plugged it in and was in the process of using it when it shut down on its own. And instantly a little green guy came on saying don’t turn off and my phone is in factory mode. I let it be for a bit but then curiosity got the better of me and I had to investigate.

In the past on two occasions, my phone was really hot to touch and the other time it just froze and would not let me do anything. Now my phone won’t start…it won’t even recognize being plugged in.

As many other people these days, I live off my phone. Everything from contacts, appointment, to alarm, to wake up.  I desperately need this phone to its former glory. Please help. I am currently using my son’s phone just for this email.

Please help. — Asi

Solution: Hi Asi. There’s little to nothing that we can do in terms of troubleshooting if your phone no longer boots up normally. Potential solutions in this case are limited to checking if you can boot the device in alternative modes. A good way to start is by booting it in Recovery mode by following these steps:

  • 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.

Under Recovery mode, you’ll the options to wipe the cache partition or do a factory reset. If you can boot your phone in this mode, then you are in luck. Make sure to do a factory reset to go back to normal mode.

In the event that Recovery mode is unreachable, try to restart the phone in safe mode (steps provided). You can also try to see if Odin or Download mode is feasible. Simply follow the steps on how to boot in recovery mode but make sure to press Volume Down, Power, and Home buttons.

While in download mode, you should be able to install stock or custom ROM (firmware). You can search for instructions on how to flash a ROM to a Galaxy S6 via Google.
