However, there might be cases wherein the problem is caused by something else–something serious. That’s why below, I will give you the most common solution as well as further troubleshooting procedures that might just help you bring the phone back to life.

Just before we continue though, if you don’t want to go through the hassles of troubleshooting this problem and you’re still within the replacement period, I suggest you just go directly to the store and request for a replacement while you still can.

Most of our readers are bound by contracts with their respective providers so if the phone isn’t working fine since day 1 and didn’t have it replaced, you may be stuck with a defective unit until the contract is finished. You don’t want that to happen to you.

Now, for owners whose problems just came out of nowhere, you might want to take a few minute troubleshooting it to see if you can make it work again and for those who have other concerns, you may visit our S7 Edge troubleshooting page and try to find issues that are similar to yours. Use the solutions we suggested or if you need further assistance, contact us by filling up this form.

Step-by-step Troubleshooting

The first step is the most effective way to fix this problem while the rest are the basic troubleshooting procedures you need to perform learn what the issue really is.

Step 1: Your Galaxy S7 Edge may have crashed, so do the Forced Reboot procedure

For system and app crashes, minor firmware issues and hardware problems that resulted to the freezing, hanging and being unresponsive, the Forced Reboot procedure is a very effective procedure. It is equivalent to the battery pull in Galaxy devices that have removable batteries.

All you need to do is press and hold the Volume Down and Power keys together for 7 to 10 seconds and the phone should restart given that there’s still enough battery left to power its components.

If the first attempt didn’t work, try plugging your device in to charge for at least 10 minutes and then try again. But if it still didn’t work, try holding the Volume Down button first and then hold the Power key.

Should the phone refuse to turn back on or respond with this procedure, then it’s more than just a simple system crash or minor firmware and hardware issues. Try doing the reset of the steps.

Step 2: Try booting your Galax S7 Edge in safe mode to temporarily disable all third-party apps

Apps may have something to do with this problem and since we don’t know if it’s a third-party or pre-installed, you need to isolate the problem and you can do so by restarting your device in safe mode to leave only the pre-install apps to run.

  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.

Assuming the phone successfully booted up in safe mode, it is almost certain the problem is with the third-party apps. There must be something you have installed that’s affecting the firmware and preventing it from operating normally. You just have to find that app and uninstall it. However, if you don’t know which app is it or if your device didn’t boot in safe mode, then the next step must be the last before you send the device in for checkup and possible replacement.

Step 3: Try booting in recovery mode and perform the master reset

If it is a firmware issue, booting in recovery mode should still be possible. In this mode, all necessary hardware will be powered up but the Android GUI won’t be loaded. If you can go as far as this mode and perform the master reset, the problem might be fixed. Try these steps:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. 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.

  1. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  2. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

  1. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  2. Once highlighted, you may press the Power key to select it.
  3. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  4. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  5. The phone will now reboot longer than usual.

If this fails as well, then go to the store and have the device checked or replaced.

  1. Me and my sister bought the samsung s7 around 2 weeks apart in the same store. Hers died one month ago, mine today has flashing Samsung for hours on the screen and any buttons pressing what is said in this aticle didnt help. How is this possible? Was the phone designed so it dies in one year and a half so you are forced to buy a new one? I am totally in shock. Her phone died exactly in the same way as mine. I cant belive how they can sell almost 1000$ phone what just dies after one year and a half.

  2. very helpful.i flashed some roms in a quick time.and i guess thats y my s7e got hot and totally blacked off.
    the vdown key and pw key trick works.thanks mate for life saving..

  3. Thanks for this how to WarmBoot ColdBoot SkeletonBoot HideBoot Wipe or replace info. Please, what exactly IS the firmware issue you say is at fault, so we can be assured a replaced device is clean?

    A few hours after purchase, I ran a few diagnostics on my s7edge. The onboard native Memo app was culprit to SBD (Sudden Battery Death. Memo fails when user’s lowball battery minder is reached (I keep mine at whoppingly high 25%+). Memo assures device phishability cache is maintained. It’s one of the unit’s BigDoors and has been SBD cause each time (on mine). Can’t figure why it’s called BSOD when it’s more a PhishAutoKill. Then, there’s also the SessionNoDelete that keeps active anything user thought they lost in webposts, app data-entry, etc.
