  • Battery has been depleted
  • Power button is stuck or damaged

Hi guys! My 3 days old Samsung Galaxy S7 Edge won’t work. It won’t turn on when I press the Power button, the screen is black, although sometimes there’s light at the top of the screen. I upgraded from Galaxy S5 to Galaxy S7 Edge thinking this is a superior device but it seems I was wrong. Please help me fix this problem or should I have it replaced?

Should  you need further assistance, do not hesitate to contact us by completing this form. Please provide all necessary information about the problem so that we can easily help you and provide you with an accurate solution.

Step-by-step Troubleshooting

First off, if your device is still a few days old, you are eligible for a replacement if the problem can’t be fixed by a technician. But it means that you have to go through the hassle of possibly lining up at the local store to have an appointment with a technician and wait for several minutes before being able to talk with another representative to give you the new unit. In a bid to save you from all that, I’ve outlined a troubleshooting procedure below to help you make your device work again…

Step 1: It might just be a system crash and a Forced Reboot is necessary

This is the first thing you should do. It’s easy and it’s safe. It’s an equivalent to the battery pull procedure for devices that have removable battery.

If it’s a system crash or a minor firmware or hardware glitch, then this procedure should fix it:

  • Press and hold the Volume Down and Power keys together for 7 to 10 seconds or until the device reboots.

The device will perform the simulated battery disconnect if it’s done successfully and if it still has enough battery to power up its components.

Step 2: It might have ran out of battery, so put it on charge

If the first step failed, then it’s time plugged the phone in to charge even if you know the phone has enough battery left because you’re not just actually trying to replenish the battery, you’re also trying to find out how the phone reacts if it detects current flowing through its circuit.

Plug the charger in and leave it be for, at least, ten minutes; there should be enough battery to power it up if it indeed ran out of battery.

While it’s plugged in, try to see if the LED indicator lights up. It doesn’t matter what the color is as long as it’s lit up, the device should be ok.

Another thing you have to check is if the screen displays the usual charging icon. Powered on or off, the charging icon should be displayed on the screen when it’s connected to the power adapter and there’s current flowing.

If none of these indications show, then there’s something wrong with the phone. Proceed to the last step.

Step 3: If the phone charges fine, try booting it in safe mode

Assuming that the device showed all the charging signs when you plugged it in, it’s time you tried booting it in safe mode to temporarily disable all third-party apps and services that may have caused this problem. But before doing so, I want you to try to do the procedure in step 1.

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

Step 4: If the safe mode failed, try booting it in recovery mode

The purpose of this procedure is to know whether the phone is still capable of powering all its components up. In recovery mode, Android interface won’t be loaded during boot up but all hardware will be powered up. If the Galaxy S7 Edge can successfully boot up in that mode, then it’s more of a firmware issue than a hardware one.

Step 1: Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

Step 2: When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

Step 3: When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

If the phone won’t respond after pressing and holding the Home, Volume Up and Power keys, then proceed to the last step.

Step 5: Get technical support or have the device replaced

You have no other option but to go to the store or your provider and have the device checked by the technician. If the tech can’t fix the problem, too, then you are going to received a brand-new replacement unit as long as you’re within the grace period (usually 15 days since date of purchase).

  1. Phone was at 87% batt and was uploading videos to google drive to create some space.. the google app crashed and phone froze.. had to power down.. but will not restart.
    Have tried all the steps(multiple times) but no life what so ever…typically the phone is 1 year and 1 day old today..

  2. NOTHING listed here does anything. I replaced my Galaxy S7 Edge a few months ago, but kept it around for a backup. I’ve powered it on and charged it up every few weeks. I tried to power it on this morning to get a couple apps off of it and it wouldn’t start. No screen flicker – no sign of life at all. I figured I must have forgotten to power it off and it needed a charge. I tried plugging it in with multiple cables and nothing happened. I put it on a wireless charging stand, and while the stand itself glowed green at the bottom (as it does when something is charging), when I tried to power on the phone after 1/2 hour, still nothing. I’ve tried to start it in safe mode – I’ve tried all the suggestions I could find. It’s just dead. And nothing happened. It was just sitting in a drawer!

  3. So my phone is stuck at the Samsung Logo when trying to start it. It won’t either start and I cannot turn it of either. It just keep blinking Samsung. The phone was completely depleted last night. Also I did push it off the bed so it has hit the floor. Any suggestion what I can do?

  4. Hey, i’m still having problems with mine.
    It went off and and its not coming on.
    When i plug it to charge, it just keeps on vibrating at intervals and a battery icon with the thunder sign keeps on flashing. I’ve left it to charge for over an hour.
    Once i try switching it on, it shows the samsung logo screen and goes off immediately.
    I’ve tried removing the back panel and trying to touch the battery area carefully incase the position might have shifted but no response still.
    What do i do?
    Thanks

  5. My S7 edge has began to turn on again after I did the very first step shown for you, so thank you very much, because you’re saving me to pay the deductible on my replacement plan.

  6. OH thanks very much. You have just cooled off my stress. I cannot believe it turned on again. IT is amazing…. it is so so helpful.

  7. Had this phone since release day. Woke up, took phone off the charger and it wouldnt turn on. I thought maybe my wall outlet was bad or something, but then none of the other outlets would charge my phone, not even another charger.

    Step one worked for me! Phone booted back on (full 100% battery, btw). Thanks again!

  8. Have had my S7 Edge since December with no issues. Screen was black this morning. I had no idea what to do. I use my phone all day for work. Searched on line and found your page. Holding the volume down and power button at same time rebooted the phone on the first try. THANK YOU SO MUCH!!!

  9. you saved my freaking life man. i had interviews today and i coudnt get this damn thing on for nothin! thank you for saving me before i tried to remove the back cover or had to make a dumbass trip to verizon! thank you thank you thank you!

  10. thanks a ton…. i was very frustrated when in morning i find my phone dead, but your post make my phone alive again….thanks bro for help

  11. Thank you! The volume key while holding down power button worked! Fuck yeah mother fucker.

  12. I had my S7 Edge charging earlier and notice it took nearly 2 hours to fully charge from 11% to 100, that is with fast charging enabled in battery settings. I was concerned. but plugged it from the charger and left it on by bed. about five hours after, I clicked the home button to get the time, as I don’t use the Always on Display setting. When I clicked the button, nothing happens, I took it up and clicked it firmly again (Just to make sure I was pressing it the correct way) Yet still nothing happens. The screen remains black and the power button does not respond.

    After seeing that something is wrong, I turned to my computer to get some help and information about this issue, as This phone is brand new, not even a month old. Before though, I said to myself, Let me try to get into the recovery mode. So I held down the power button, the volume down button and the home key. And like Magic it rebooted and came on like nothing ever happened. After that I turned it off, and power it back up again. And it booted normally, I quickly Googled this occurrence, and found this article and thousands of other users with similar issues.

    I read this article first, and behold. The first procedure was the one I did, and it worked instantly. I now realize that this was a firmware issue and not a hardware one. I remember getting the Android security patch this This week, and from then my phone was behaving weird. I do wonder what could have caused this to happen?, could it be that the security update caused the system to crash?. As after the update, I notice my phone was charging slowly with fast charge enabled. I really hope this does not happen again. For such an expensive premium device, this should not have happen, I pray to God it wont happen again.

  13. I’m restart my phone cuz play store won’t response but my gs7 edge never turn on again why ? Omg is frustrating

  14. Well, now my phone is responding, finally showed some life! Used step one an it decided to respond. lHad it in an Otter holder I guess that the holder was interfering with the switch contacts. Removed the hoolder and it came back to life.

    Thanks for your web site!

  15. thank you so much I was so worried about my new edge since it did not turned on and it was too hot to touch to.. when i got home i hurriedly placed it inside the chiller ehehehe to ease the hotness, then i decided to let it fix but i think of searching some alternatives on how to fix it myself before letting it fix by other people that might damage more the mobile..haha..luckily i came to this site and then i followed the step 1…wheeeewwww what a relief..thank you so much again for this, such a big help for me…save my money as well haha..cheers!!

  16. Thank you so much for your help! I was ready to give up and go to the Sprint store but decided to look up how to fix it when it it won’t turn on. Again, thanks so much!

  17. my phone is not responding. it frizzed and turned off itself. now I cannot turn it on back 🙁
    I do not know what happened. why?

  18. had my phone since October 2016 (company phone), had nothing but problems with the thing, now I have a completely black screen, totally unresponsive, tried all of the above steps. Have already gone a full factory reset, used it in safe mode and still the thing dies on me. Hopefully now Vodaphone will replace it as I am totally fed up. Beginning to really hate Samsung S7 Edge with a passion. My personal S6 works a dream.

  19. Phone would ot charge. No Charging light off standard Samsung charger that came up with phone that always works with it. Tried off a PS4 and laptop, too, making sure it was not a device or cable related issue.

    1)Tried the reboot, brought up “Android updating” screen, but it the showed a screen showing it was crashing.
    2)Phone turned off, and I was able to restart it with the Volume down and Power and selected “Safe mode” and pressed the power button.
    3) It is now just blinking blue and green (for 3 hours+ now), not responding to any power or combination of power and vol down;; tried the power and up, tried the power up, home, and vol up… NOTHING.

    HALP
