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.

Before we proceed, if you have other concerns, visit our Samsung Galaxy S6 Troubleshooting page as we listed all problems we already addressed in the past. Find issues that are the same or related to yours and try the solutions we provided. If they didn’t work for you, then feel free to contact us as we are always willing to help but make sure you fill up this form accurately so that it will be easier for us to help you.

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.

  1. awesome i hold the volume botton down & da power botton at da same time for 7 second and it worked!!! thxs Andre 😉

  2. I postponed the latest update. Randomly today it just turned off and wouldn’t reboot. Wouldn’t turn on or recognize when it was plugged into my charger. Tried all of the steps, nothing worked. I plugged it into my laptop and that actually worked, it began charging and I was able to turn it on as normal. So try that if the above steps don’t work…..

  3. My s6 worked for a few hours after the last update but now it won’t charge, turn on or re boot. I tried all of the suggestions and nothing worked.

  4. S6 non start over night even after being on charge all night. Wouldn’t even show that it was charging. I did update the PRL and one other thing yesterday but phone worked after that.
    So I tried the power and volume down button like suggested and nada. Starting to freak at this point.
    Got a different charge cord and changed outlets. As soon as cord was inserted phone showed charge icon then battery display went o 96%. Held down power button and phone started.
    What do I need to do to prevent this from happening again? Side Note: I have Sprint for my phone carrier and for the last 6+ yrs had Samsung phones. Phone has died each Aug or Sept in the second yr of ownership and the sprint contract renews each Nov. Is this a coincidence?

  5. unfortunately did not work for mine. wont charge wont turn on i guess i will have to take it in to a shop to be repaired and they wipe all the photos and memory honestly i will never get another samsung phone 6 months still on my contact to run and with a completely dead phone. its not the first problems I have had with it I have had problems with it before just always managed to get it back on again, I am sure it is always the software fixes that cause the problem. it certainly has caused a problem for me. very unhappy.

  6. So happy that Step 1 worked!! Is it a coincidence that so many of us had our Samsung phones go dark all around the same time???

  7. Oh thank this page< my galaxy s6 just Froze (before i thought it had died) turned out all i had to do was force a restart bookmarked the page for the future.

  8. My Samsung s6 just died last night at 2 am. Samsung have taken it and are going to wipe the phone and lose all my photos. Was there a software issue last night?

  9. I was almost sure my phone died this morning. Holding down the powerbutton for some time didn’t do the trick this time and not any feedback when putting on charger.

    However, coming across this posting and trying Step 1, to my surprise, actually worked!
    Thank you Harold! you saved me a LOT of trouble..

  10. Thank you so much! All of a sudden my phone stopped working, step one did it’s magic and so far so good! Everything is working again!

  11. Sheesh. Out of no where my phone was locked, no response. So great that folks have place like this to research the answer. Holding the power button and down button worked.

  12. This worked for me! Thank goodness for your article bc I was about to bring it to a tech. Thank you!

  13. thanks this saved my life as I am offshore when it happened. the power key and volume keys worked like magic.

  14. Held power button and volume down button for 7 seconds got phone to respond (phew!)
    Thank you!

  15. Same here…
    Held power button and volume down button for 7 seconds got phone to respond. Awesome!
    Thanks!

  16. My Samsung S6 will not turn off. It did a system update and it wont allow me to access my phone via a pattern. It won’t allow me to turn it off as I need a pattern and it’s not accepting my pattern or my backup passcode. I have been trying many different ways and I may have to factory reset, and I haven’t backed up my photos! Grr. But how can I turn it off when it won’t allow me to?

  17. Holding power button and volume down button for 7 seconds got phone to respond. Thanks

  18. please my phone is locked and dont know how to open it.custom binary locked byfrp lockoppong

  19. Thank you very much for your descriptions. The “Step 3: Attempt to turn the phone” was helped me.
    You are doing great job.

  20. Thank you! The power key and volume down for 7 sec worked for me! My phone just did an update yesterday and I woke up this a.m. with this problem. What a relief.

  21. None of these worked for me, but I appreciate you sharing your tips.

    Here’s what happened to me before it stopped working – I knew my battery was very low, I tried to turn it on and it vibrated and powered off so I placed it on the wireless charger. The large battery charging icon displayed and showed that it was charging. I left it overnight to charge. The next morning the LED was green (I think) and the display showed the battery icon at 100%. I held the power button to boot it up – nothing. That was a week ago and there has been no signs of life since then. It doesn’t respond to a charging cable or holding any button combinations.

    I had installed the latest OTA update a week or two before it died – I don’t know if it’s significant, though it is interesting that several people have reported this issue in the past month.

  22. Mine doesn’t work… it just closed randomly, I didn’t even notice. And when I pulled it out of my pocket to check the clock, it was closed. I’m trying to charge it right now, but nothing seems to work, no LED opens or anything… I also tried pressing the volume down and home, but still nothing. I don’t know what to do with it.

  23. Looks like this happened to quite a few of us in the last couple of days but step 1 worked for me. Thank you!!

  24. Very helpful! Thanks for this post, I read about 3 articles before stumbling to this blog, will save it in my favorites – the instruction are simple to follow.

  25. You’re a lifesaver. Luckily, step 1 solved my problem THIS time, but I could’ve used this article a few times in the past.

  26. Thank you. My best mate “Ted” a German Shepherd died 6yrs…………….I lost the plot and got wasted!! Charged the phone but the screen was blank. Followed your instructions…and hey ho..got my phone screen back. Many thanks…………….you are a star. Mx

    Thank you

  39. After I pressed the volume down and the other buttons, it asked me if I want to continue installing a custom OS??? I never downloaded or even tried to install a custom OS?!
    So I just canceled it and it restarted.

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

  41. 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 🙂

  42. 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

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

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

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

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

  47. 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.

  48. 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!!
