Samsung Galaxy S7 Won't Turn On

Nothing is worse than wanting to use your smartphone only to be hit by a problem that prevents you from doing so.

All smartphones are subject to errors from time to time (some more than others), and fixing those errors can be a pain.

Software glitches and faulty hardware can be to blame, but resolving the problem typically doesn’t require urgent attention.

This article will focus on the fact that the Samsung Galaxy S7 won’t turn on that S7 users may experience.

It’s safe to assume there are hundreds of reasons for the device not turning on. To mention a few: hardware damage, corrupt firmware, and a fried motherboard from overheating.

Setting aside the reasons for not turning on your Samsung Galaxy S7, what do you have to do to fix it?

Solution #1. Plugin the Charger to Fix Samsung Galaxy S7 Won’t Turn On

Smartphone batteries aren’t the most powerful, and many owners find that between leaving their house in the morning and arriving home later, the battery dies. A portable USB charger can prevent the battery from dying, but even this is sometimes not enough.

So, if Samsung Galaxy S7 won’t turn on for you, the first thing to check is if the battery has a charge. Plug the phone into a power outlet and wait between 20-30 minutes.

This makes sure there is enough charge before you try to power it on. After this time passes, try to turn the Samsung Galaxy S7 on again.

Plugin the Charger

Hopefully, you notice the device’s lights glowing, which powers on once again. Here are a few ways to minimize your battery consumption:

  • Stop any unnecessary background processes
  • Avoid playing battery-draining games
  • Only download and install firmware updates at home
  • Don’t make long phone calls
  • Uninstall unused apps that run in the background

Take these tips into consideration; your battery consumption will be low, and there’ll be minimal risk of the battery dying before you get home.

  • #2 – Continue holding the buttons for roughly 10-15 seconds.

Solution #5. Boot Samsung Galaxy S7 in Safe Mode

Booting a device in Safe Mode means the operating system loads without any unnecessary additions.

As a result of using Safe Mode, you can determine whether or not the firmware, hardware, or your apps are to blame. Booting in safe mode is different for each Android device, so here’s the method for the Samsung Galaxy S7.

  • #1 – Press the Power button until you see the Samsung logo.
  • #2 – As soon as the logo appears, release the Power button and hold the Volume Down button.
  • #3 – After a few seconds, your device should reboot.
  • #4 – Once the reboot finishes, you’ll be taken to the main menu, where you can select “Safe Mode.”

  • #5 – If your device turns on without any problems, then the problem could be with third-party apps.

If entering safe mode still leaves you with a Samsung Galaxy S7 that won’t turn on, then it’s safe to assume it’s not because of your apps or third-party customization tools.

But if this does fix your problem, delete any apps that aren’t from the official Google Play Store, as they could be causing it.

Solution #6. Wipe Cache Partition

Doing a cache partition wipe can be useful often, not exclusively for repairing Android system errors. This process is simple: when you download updates, the device uses the cache to store some important required data.

This data isn’t removed from the cache; over time, it starts filling up and slowing down the device.

By wiping the cache partition, this cache storage can be used by the device in other ways which enhance its performance. So, here’s how to wipe a Samsung Galaxy S7’s cache partition.

  • #1 – Press and hold the Home, Volume Up, and Power buttons together.
  • #2 – Continue holding these buttons for roughly 7 seconds.

  • #3 – Stop holding the Home and Volume Up buttons when the Samsung logo appears.
  • #4 – The Android System Recovery menu will now appear on the screen. Using the volume buttons, move down the menu and highlight “Wipe Cache Partition.”

  • #5 – Once this option is highlighted, press the Power key to select it.
  • #6 – Your device will start running the cache partition wipe process, which shouldn’t take long. Afterward, you’ll be taken back to the menu where you can select “Reboot System Now.”
Reboot System now
  • #7 – The S7 smartphone should now restart and load the Android system normally.

If you wait a few minutes and your smartphone doesn’t load normally, the cache partition wasn’t causing Samsung Galaxy S7 won’t turn on. In that case, move on and try the next solution.

Solution #7. Factory Reset Your Android

We recommend only doing this if absolutely nothing else was helpful. A factory reset will completely wipe the firmware installation and then reinstall a fresh copy – this is useful if the error is because of severe firmware errors that prevent it from loading.

In doing so, though, your data will be removed too. Any photos, videos, documents, texts, and other personal information will be gone.

Hopefully, you take backups regularly, making this a more viable solution. Moreover, acquiring your data won’t be easy since you can’t turn on your device.

Nevertheless, if you’re out of options, here’s how to factory reset a Samsung Galaxy S7.

  • #1 – Start taking your Galaxy S7 end and entering the Android System Recovery menu.
    Note: follow Steps #1-3 in Solution #5 if you are uncertain about getting to Android System Recovery.
  • #2 – Using the volume keys on the side of your smartphone, highlight the “Wipe data/factory reset” option, and press the Power key to select it.

  • #3 – Wait while the factory reset process takes place. The device may restart several times while this happens.

Note: as you will not be able to check your battery life, plug in your smartphone so that it is actively charging and doesn’t run out of battery during the factory reset.

  • #4 – After the factory reset is complete, you’ll be able to turn it on again and set it up from its default state.

Afterward, you can restore a backup if there’s one available. Due to this being the final solution on the list, you should no longer be dealing with Samsung Galaxy S7 won’t turn on.

What if None of These Solutions Work?

So, as you finish factory resetting the smartphone and realize it still won’t turn on, you now wonder what’s next.

We’ve exercised all the effective solutions for errors you can try from home. It’s possible that the issue is because of a hardware problem.

If that’s why then there are some things to consider:

  • How new is the Samsung Galaxy S7?
  • Do you have a second-hand smartphone?
  • Did you recently buy the device?

If you’ve only recently bought it and taken it out of the box, it may just be that you received a faulty unit. On the other hand, if it’s second-hand or you’ve had it a while, general wear and tear could explain why it isn’t turning on.

Buying something only to find out it’s broken usually warrants a free replacement. Simply take it to the store you bought it from, and they’ll sort out the situation. Similarly, most phone shops also offer repair services and can help.


1. My Samsung Galaxy S7 is not charging. What should I do? If your device is not charging, try using a different charging cable and power adapter. Clean the charging port of your device using compressed air or a soft brush. If the problem persists, consider visiting an authorized service center for further assistance.

2. Will a factory reset delete all my data? Yes, performing a factory reset will erase all data and settings on your device. It is crucial to back up your important data before proceeding with a factory reset.

3. Can I fix a faulty power button on my own? Repairing or replacing a faulty power button requires technical expertise. It is recommended to seek assistance from a professional technician or an authorized service center to ensure proper repair.

4. How long does it take to perform a factory reset? The time it takes to perform a factory reset may vary depending on the device’s storage capacity and the amount of data stored. It can take anywhere from a few minutes to several hours.

5. Is liquid damage covered under warranty? Liquid damage is usually not covered under the standard warranty provided by the manufacturer. It is best to check the terms and conditions of your warranty or contact the manufacturer for more information.

To Conclude

Understandably, you need to fix Samsung Galaxy S20/S10/S9/S8/S7 won’t turn on as quickly as possible. This is one of the errors that completely stops you from using the device, and most users will agree that urgent repair is needed.
