How to fix Samsung Galaxy S6 that won’t turn on [Troubleshooting Guide]

There have been reports from some owners that their Samsung Galaxy S6 won’t turn on for some reason. In fact, we did receive a few emails from our readers regarding the issue. The thing about this problem is that the cause is not apparent. There were cases wherein the problem was caused by a hardware glitch and there were also instances that the firmware triggered it.

For us technicians, it is imperative that we know what the problem is so that we can provide accurate solutions. But in this post, you will be the one to troubleshoot your phone. The purpose of your troubleshooting is to know what caused the problem and whether or not you can do a thing or two to fix it or you need help from a technician.

I will guide you through proper and safe troubleshooting of this problem. By proper, I mean the troubleshooting procedure we technicians often follow, and by safe, I mean not putting your phone and your data at risk or cause further trouble than help.

However, there are always unforeseeable risks so follow the steps at your own risks. Remember, your phone won’t turn on even before you started reading this post. If you managed to make the screen light up, then that’s already an achievement.

Troubleshooting

Our main goal for this troubleshooting guide is to make your Galaxy S6 power up or, at least, respond when you press the Power key. Of course, let’s begin from the basic troubleshooting to more complicated procedures.

Step 1: Verify it’s not just a freezing issue

Both hardware and firmware glitches can cause lagging and freezing problems. The first thing you should do is to rule out this possibility. If it were like the Galaxy S5 and previous models, you could just pull the battery out for a few seconds and turn the phone back on. However, the Galaxy S6 doesn’t have a removable battery so when it freezes and you don’t know how to force restart it, your only shot at fixing the problem is when the battery is completely depleted. But then again, you will never know if such was the case because the device won’t respond and couldn’t show how much battery is left.

To rule out this possibility, all you need to do is to press and hold the Power key and the Volume Down button for 7 seconds or more to force restart your Galaxy S6. Repeat the process if the phone didn’t respond for the first time or until you’re satisfied you did this step correctly.

If the phone has enough battery left and was only frozen, the problem should be fixed at this point. Otherwise, you have to proceed to the next step to rule out yet another possibility.

Step 2: Allow your phone to charge

If the phone didn’t respond when you pressed and held the Power key and Volume Down button, it doesn’t mean the phone is already defective. Maybe there’s not just enough charge left in the battery to power up the components so plug it in to charge.

Assuming the battery was totally depleted, it may take a few minutes before the phone will display the usual charging icon or light up the LED indicator. Allow it to charge for, at least, 15 minutes.

Aside from the obvious reason to charge the phone, this step will also tell you if the phone responds to an active charging unit. After 15 minutes and the charging signs don’t show, then it’s more of a charging issue than anything else.

Step 3: Attempt to turn the phone

This problem could be easier to fix if the phone charges because that’s a sign the device still accepts current from the charger to its battery. However, if the charging signs didn’t show but you’ve plugged it for 15 minutes, attempt to turn the phone on just to see if it’s still capable of doing so.

You may also try pressing and holding the Power key and Volume Down button for 7 seconds or more (like what you did in the first step) just to force restart the phone.

Step 4: Boot the phone in safe mode

After charging it and it won’t boot up normally, then it’s time you try booting it in safe mode. There were cases where third-party apps caused phones to freeze or not boot up.

  1. Turn off your Galaxy S6 Edge.
  2. Press and hold the Power key.
  3. When ‘Samsung Galaxy S6 Edge’ appears, immediately release the Power key and then press and hold the Volume Down button.
  4. Continue holding the Volume Down button until the phone finishes the restart.
  5. When you see Safe Mode on the lower left corner of the screen, release the button.

Step 5: Try booting it in recovery mode

If your Galaxy S6 refused to boot up in safe mode, then it’s time you tried booting it in its barebones. Booting in recovery mode will still power up all components but Android interface won’t be loaded. If the phone can boot up successfully in this mode, then the hardware is fine and the problem might be caused by the firmware itself. You may proceed with master reset if successful.

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.

Step 6: Send the phone in for repair

If all else fails, you need help from a technician. You may contact the retailer where you bought the phone or your service provider if it came with a contract. As far as troubleshooting is concerned, you’ve done everything to bring the phone back to life.

  17. That moment wen u read comments and they are all’thank u, it worked’. i tried everything but its not working

  18. Hi guys.
    Did what you said about pushing the buttons as my galaxy 6 died on me for no reason. Great tip worked firstctime thanks 🙂

  19. It did not work for me, my phone still won’t turn on, I’m dreading the worse and now think that the phone is faulty

  20. Thank you your information helped so much and now its working ,i cannot describe the feeling of realef thanks

  21. Thank you! I went through the Sprint website and their site wasn’t working properly! It was super annoying. This did it in seconds.

  22. Thanks guys, my phone is working again. I followed your instructions for the S6 and it came back on.
    Thanks again.

  23. Woke up this morning very mad at my phone because it wouldn’t turn on. Step 1 worked instantly, so I thank you lots!

  24. Thanks!! This advice worked to take care of my black screen problem. I have had my s6 for 2 years with no problems. I was going to purchase a new phone. You saved me about $600.00. Happy l tried your website. Koodos to you.

  25. Thanks for your help restarting my S6. However I found the power button/volume down needed pressing for much more than the 7 seconds suggested. I tried twice for about 10 seconds without success. Third try I held the buttons down while reading this page for more tips. When I looked down at the phone it had just started the reboot, would guess at about 20 seconds. May be worth a try if your at head banging stage!!

    Much appreciated guys.
    Then it rebooted by displaying my cell charging battery then I turned it on.

    Thanks a lot again!

  28. Galaxy s6 128GB memory. Android 6.0.1 – all updated. Not rooted. Playstore apps only, including Nova Launcher, Google Keyboard.

    Did the above a few months ago. It worked. Now repeated the fault. Tried the above again. Not working. Battery is 75% or higher. Safe mode, easily entered, but fault still happens.

    Fault is that the screen will not respond. Just the 4 physical buttons and the two capacitive buttons. There is a horizontal line moving up-down the screen. Pressing any of the physical buttons will refresh the screen, and then the blue-line again continues.

    atm the blue-bakground-screen has in the center of the screen, in large letter: “Downloading… Do not turn off the target”

    In the top-left of the screen, in tiny letters is an 8-line menu.

    ODIN MODE
    PRODUCT NAME: SM-G920i
    CURRENT BINARY: Samsung Official
    SYSTEM STATUS: Official
    REACTIVATION LOCK: ON
    Secure Download : Enabled
    KNOX WARRANTY: 0 (0x0000)
    RP SWREV: B:3 K:2 S:2

    From previous experience with this menu, it takes hours (?) to download anything?

    Generally I stop it after an hour. Has it crashed? My phone is at home, wifi-linked to our home router, on a fast cable network. No troubles with the wifi & internet connections. Also the Samsung phone can have a SIM CARD in it, with Data to download as well, but I’ve moved the Sim card into an older working phone.

    I’ll let it “download” wifi, overnight now, and see if it is ok in the morning. In the meantime, the screen is full-brightness, without any ability to lessen the brightness.

    The first time this happened, I chanced into a menu which enabled me to return the Galaxy s6 to factory defaults. I’ve yet to figure out how I chanced upon this method.

  29. Thank you!!!! My phone was fully charged but would not turn on. Only reason I made it to work on time is because my dad luckily woke me up. The power button + volume down for 7 seconds did something, I could see it had 99% battery but then black screen again. I tried the power button and it turned on and is working as if nothing ever happened. So weird…thanks!

  30. THANK YOU!!! I knew how to force restart my ipod, but was new to android and wasn’t sure, thank you very much m8.

  31. i got my phone too work thanks i plugged in my charger and was going too bed and got up later and looked at my phone and did not turn on…… so i held the power butten and volume down butten and it works now……. i think my charger made it glitch out lol

  32. Thank you so much! This is what I thought I needed to do (let it die down then charge it) but this confirmed my beliefs. Also this taught me about other modes incase anything goes wrong too 🙂

  33. Got the same problem. Managed to fix it by plug in the charger, wait for the charger icon to disapear then directly after that using the Step 1!

    This was after about 100 try!

  34. Thanks, the first step help me out. My S6 wouldn’t turn on but I held the Power button and the down volume button for about 10 seconds then it rebooted by displaying my cell charging battery then I turned it on, Thanks a lot! I was about to run it to At&t.

  35. Thank you! Your troubleshooting helped me turn my s6 back on using the volume buttons. I even took it to AT&T and they couldnt figure it out! Still going to take it to the main store to have it looked at. The back base was hot after it automatically shut off. Thanks for your help.

  36. Thanks a lot… got my phone started after the first step… thanks again… hope that you will continue to save lives like these in the future.. have a good day.. 🙂

  37. Thank you very much for this info. It allowed me to boot up, and I wasn’t concerned that I would void any warranty or worsen the problem!

  38. Thank you so much for this information. Your a life saver! I just got my s6 one day ago, and woke up to a frozen screen. Should I be worried about this as the device is only 2 days old?

  39. None of this helped me, no website can help me! My sprung galaxy s6 freezes on the sprint spark screen from the boot up, I’ve restarted it and wiped cached partition but nothing. Just freezes right after the sprint spark animation finishes. Just gets stuck on this yellow screen nonstop. I woke up to my phone like this.
