Hello everyone. Welcome to the most recent #GalaxyS6 post for today. We hope this material will become another useful reference for you.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: PC not detecting Galaxy S6 when connected via USB cable

I just got the most recent update 7-13-2017. After this update my Samsung Galaxy S6 will not connect with my computer. The laptop does not recognize the device. I have gone to turn on the USB debug. As well as made sure MTP is selected. My friend who has the LG V20 is encountering the same problem. We have made sure to use cords the MTP (cords) and not the charging ones. We have also gone on and reinstalled the phone drivers for the laptop and it has not fixed the problem. After extensive Google and setting search we are stumped. Do you have any solution? (The Galaxy S6 is Sprint carrier, and the Samsung LGv20 is T-Mobile carrier). — Justine.benavides7

Solution: Hi Justine.benavides7. Installing an update for your phone must have changed some configurations in the device including drivers and firmware needed by your PC. To ensure that your computer is equipped in detecting a Samsung device like your S6, you must install Samsung Smart Switch. We’ve created a special page from one of our affiliate sites on how to create a backup using Smart Switch app in a computer so if this is your first time to use it, follow this link.

Also, LG V20 is not a Samsung device; it’s from LG. Make sure to tell your friend to use LG Bridge program. This is a backup tool similar to Samsung Smart Switch and it must be installed in the computer as well.

Problem 2: Galaxy S6 don’t make sound notifications

Hi. I think I have a Samsung S6 or 6+ (it has a really big screen.) I’ve lost all notification sounds; texts, voice mail, email. I tried soft boot, alarm clock sound works, music works. Sounds DO NOT work in Safe Mode. To make matters worse, I can’t get out of Safe mode. I tried everything except removing the battery, because it’s a real chore to take off and put on the protective sleeve. Any and all help would be greatly appreciated. I don’t keep the phone on me, so I can’t keep glancing at it to see if I have a message. — Danny.tutorpros

Solution: Hi Danny.tutorpros. If you’re 100% positive that you’ve already set the correct settings under Settings>Notifications for each app you’re having problems with, the first thing that you want to try is to clear the system cache. This will force the phone to delete the current cache and replace it with a new one as you continue using the phone. Sometimes, updates and app installations can corrupt the system cache, resulting to all sorts of problems. To bring it back to its working condition, simply wipe the cache partition where it’s stored. Here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

If a cache partition wipe won’t fix the issue for some reason, do a factory reset. This will ensure that you return all software settings and eliminate possible bug that may have developed over time. Once you’ve done the factory reset, make sure to test how sound notifications work right away, and before you install any app. If the problem remains even when there are no apps, that’s indicative of a possible coding or operating system issue. Unfortunately, there’s really nothing that you can do about that except to let your carrier know (so they can inform the developer team), or simply wait for a new update.

If the problem won’t occur after a factory reset, but does after installing back your apps, there must be a problematic app causing it. To identify the app, you want to use the process of elimination. Basically, you just want to invest time installing an app individually at a time, and observing how sound notification works. Do the cycle until you identify the problematic one.

To factory reset your S6, follow these steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S6 Edge.
  3. Press and hold the Volume Up, Home and Power keys together.
  4. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  5. Wait until the Android Recovery Screen appears after about 30 seconds.
  6. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  7. 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.
  8. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem 3: Galaxy S6 music player changes speed and pitch randomly

This is S6, not edge but I hope you can still help. Every few songs or so, a music player will play the song at a slower rate and a faster pitch upon manual song change, i.e. the next/prev buttons or just choosing a song. When it changes, it’s always to the same speed and pitch. The only way to reverse it if it happens is to manually switch songs again, and it happens often. Please help. — Hansel

Solution: Hi Hansel. The music app you’re using may be buggy. Make sure to revert its settings to their defaults. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Alternatively, you can also try to uninstall the app (if it’s third party) and see if re-installing it will work. If the problem returns after wiping its data, or after reinstallation, you should move on and pick a new music player app.

Problem 4: Galaxy S6 apps keep opening by themselves

I have a Samsung Galaxy S6, the cover includes a flip open screen protector, which does not include a magnetic on off switch. (I’m not sure if the S6 has a magnetic switch, my Samsung Galaxy TAB A does, and when I close the screen cover the display turns off). My S6 starts numerous apps without my selecting them, this happens when the phone is in my pocket, but also when left untouched and or unmoved. Also files are opened, and settings are also opened. I don’t use a screen lock. — Doug

Solution: Hi Doug. Unless there’s an unknown software glitch that send commands to the operating system to open apps at random, we would like to think that the problem may lie on the touchscreen. It may be detecting false touch inputs causing it to open icons by mistake. Make sure that the screen is cleaned by wiping off any fingerprints and traces of it anywhere. Once you’ve done that, pull up the service menu to do a simple test. Here’s how:

  1. Open the Phone app or the default dialer app you’re using.
  2. Dial *#0*#.
  3. Tap the Touch box.
  4. Observe the phone for a few hours to see if lines will show by themselves. If the touchscreen is defective, lines should be generated automatically in this screen without you touching it.

If everything appears normal, simply tap the back button a few times to return to normal mode. You then want to do a factory reset to see if there’s any software glitch causing the trouble.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap the Settings icon.
  3. Under the ‘Personal’ section, find and tap Backup and reset.
  4. Tap Factory data reset.
  5. Touch Reset device to proceed with the reset.
  6. Depending on the security lock you used, enter the PIN or password.
  7. Tap Continue.
  8. Touch Delete all to confirm your action.

Remember, if the issue continues even after a factory reset, there may be a hardware issue behind. Let Samsung or an independent technician check your phone.

Problem 5: Galaxy S6 4G keeps disconnecting

My phone started having network issue today. Being 15/07/2017 Whenever I turn the 4G on it will start misbehaving like the network will start going off and coming on, like that until I go and change it to 3G, then it will stabilize. What could be the cause of this issue? Please help. I need your help. My phone is Samsung Galaxy S6 edge running on 6.0.1. — Okere

Solution: Hi Okere. Was 4G working on this device before? Did the issue happen out of the blue? These are some of the questions that you can only answer. If the problem is a recent development, it’s highly possible that it’s a network-related problem. Your carrier may be experiencing system problems in your area so the first thing that you need to do is to contact them. Don’t do any troubleshooting on your device until you’ve contacted them first. That’s because it’s logical for them to then assist you troubleshoot the issue if the cause is not from their end. They should work with you to narrow down possible causes.

Another thing that you can try is to insert your SIM card to another phone (if you are in a GSM network only and not in CDMA). If 4G works in another phone while using your SIM card, that means that the issue is phone-related.

Because there’s not enough information that you provide here, you skip everything else and do a factory reset right away. We don’t know what happened to your phone prior to this issue so you want to establish a baseline. With all software settings returned to their known working state, 4G is supposed to work normally fine as well. If the problem returns though, it’s possible that the issue may be hardware in nature. Try to check for updates and install them. If the issue persists, have the phone repaired or replaced.

Problem 6: Galaxy S6 SMS conversations are out of order

My text message conversations are not in chronological order. NOTE: I am NOT talking about the messages themselves. When I open the regular text messaging app, the conversations page when you click on the name or number of the conversation you wish to view/text.. the contacts/conversations used to be ordered with the most recent conversation at the top. For the last few months they have been in an order i can’t even find a pattern on. My mothers’ conversation reordered to the top but this guy i have been texting with nonstop is so far down the list. i can’t even find it. Under my mother is someone i haven’t texted within a week, followed by someone i haven’t talked to in a month. It seems like randomly someone i text will reorder itself at the top and stay there. My work around is to use the search feature at the top. Please help me get my conversations reordered correctly! Thanks, Katie Jo – Samsung Galaxy 6 Edge. — Katie Jo

Solution: Hi Katie Jo. Make sure that the system time, system date, and timezone are set correctly first. You can do that by going under Settings>General Management. Having incorrect time and date usually scrambles the order of conversation threads.

If that’s the cause of the problem, there may be a bug in the messaging app so you want to clear its data. This procedure will delete your messages so make sure to back them up using Samsung Smart Switch first.

To wipe the data of an app, follow these steps:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Problem 7: Wet Galaxy S6 won’t turn on

Dear team, I have read your blog and found partially information about my problem but I’m still lost and I prefer to send you a message.

Today I dropped my phone which was only charged 13% into the sea for about 4 seconds. Once we took it out, we have dried it off immediately but it was still working fine. After, it de charged really fast though so once we came home I put it on charger and I had the overheat sign for the battery. So I have put it I to a ball of rice plus the fridge. After 30min I took it back just to see what happens. if I put it on charger and it moved to factory reboot and had a blue screen written “downloading, don’t turn of” which was on for about 15min (while charging) but after those 15min the screen just simply turned black. I tried to power it on but nothing. So I have put it back into the ball of rice an another half an hour tried again but the phone screen stays black and nothing is going on. I’ll leave the phone in the ball with the rice but do you know how I could recover any data if it would not turn on? (I don’t use cloud service). Many thanks for any idea I could do! Kind regards Blanka.

P.S. I’m not sure about software version – sorry about this… But I have done this morning a software update and it is original software from Samsung and android – no jailbreak. — Blanka

Solution: Hi Blanka. Your Galaxy S6 does not have water resistance protection like the S7 or S8 so the obvious reason why the phone won’t turn back on right now is hardware malfunction. Putting the phone in a bag of rice won’t do any good at this time. The best thing that must be done is to let a professional check the hardware physically so it can be assessed. If you’re lucky and the damage is isolated to the battery and/or the screen only, replacing them may fix your problem. If it goes beyond the battery or the screen, it’s more practical if you’ll just get a new phone.

And no, there’s no way to recover data from a phone that won’t turn on. If a technician can’t make the phone power back on, you’re out of luck.

Problem 8: Water damaged S6 fails to power on

Hey! So I was at the beach and hit the water with my Samsung Galaxy S6 Edge in my pocket. After a couple waves I realized and immediately got out of the water to find my phone that was once on was turned off and no longer turning on. When I tried to charge it, I noticed the phone would heat up at a quick rate, so I stopped that. It has been 24 hours and now I decided to put it in a bowl of rice, screen facing up. Any suggestions on what to do? Thanks. — Abrar

Solution: Hi Abrar. Please refer to our advice for Blanka above.

Problem 9: Galaxy S6 active screen stays black and won’t turn on

Hi. Yesterday my Galaxy S6 active was working perfectly fine. I had it on my bed. i took my phone from my bed put it in my purse and then put my purse in my car. i took my phone out of my purse and the screen was black but the blue LED light is on. It does not blink. when i hold down any combination of buttons the screen flickers.

I contacted Samsung and the closest service center is three hours away from me. i took it to Best Buy and it was really hot when they looked at it. I’m so confused. i didn’t drop it, it doesn’t make sense. The light turned off last night and when i plugged it in the light turned red. after charging for about 5 minutes i took it off and the light stayed off but once i tried to power on the screen was still black and the blue light came back on and hasn’t shut off. Please help. I am in-between jobs right now. My warranty is up already and i can’t afford a new phone. — Lizzie

Solution: Hi Lizzie. We’re here to support users with software problems. Yours looks like a hardware malfunction since the screen stayed black after attempting different hardware button combinations. That means that this issue can’t be fixed on your end. The screen may have stopped working for some reason. If it’s not that, you may be looking at another motherboard issue. Either case, you need to let a trained technician to take a look. We know this is not ideal for you right now but it’s the critical first step in figuring out what the real problem is.

Problem 10: Galaxy S6 active won’t charge by cable or wireless, how to flash S6 bootloader

Hello. I plugged in my Samsung S6 active and it was charging. I came back an hour later and it still was plugged in but not charging (the battery was not full). I unplugged it and re-plugged it in and it would not charge. Thinking it could be the port, I switched to my wireless charger and it would either A) connect briefly then disconnect, or B) connect then and say it was charging but then it would be stuck on a percent (say 4%) and not charge.

I have:


  • purchased a new charger/wall,
  • cleared the cache,
  • soft reset
  • hard reset
  • restored to factory settings.


But when I go to turn it on, the phone starts to install an update but I think the battery is too low to complete and it turns off. Any ideas? Thank you. — Forrestaperkins

Solution: Hi Forrestaperkins. Your phone has problems charging via wire and wireless so there must be a motherboard issue behind it. And that’s the reason why all the things you’ve tried never made a difference at all. The only thing that you can try at this time, and hopefully the device stays on enough to allow you to complete the procedure, is flashing the bootloader to flash. There’s very little chance that it might help but you might as well attempt it  before sending it in for repair. Below are the sample steps on how to flash a bootloader. Exact steps may be slightly different so make sure to do extra research how to do it properly.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.
