• Corrupt data in the device's memory
The new operating system includes different firmware, and this could be corrupting existing files on your device. Quick fix: Reboot in Safe Mode.
• Incompatible third party application
Some third-party apps crash because they are not compatible with the new firmware mobile manufacturers use to improve their operating systems. As a consequence, the apps prevent the device from rebooting normally. Quick fix: Reboot in Safe Mode.
• Cached data stored
The new firmware is still using data stored in your cache partition from previous firmware and is causing consistencies. Quick fix: Wipe Cache Partition.
• Hardware problem
Something could be wrong with a particular component of the device. Quick Fix: Factory Reset.
Before trying any of the following remedies to prevent your Samsung Galaxy restarting, again and again, it is a good idea to protect the data on your device, so you don’t lose anything.

We recommend the Dr.Fone - Data Recovery (Android) because it is easy to use, selects all data types, gives you the option which data you want to save and a whole load of other advantages that are merely a bonus:

The reason your Samsung Galaxy is restarting automatically could be due to one of several reasons. And different models have been experiencing different causes. Fortunately, most problems can be resolved by performing a few simple actions. However, you may have to try several of these solutions before you find the right one.
So let’s get cracking.
Solution 1: Corrupt data in the device's memory
Regardless of the model, if a Samsung Galaxy is in a restart loop, reboot the device in Safe Mode. To do this:
• press and hold the Power key to turn on your device. When the Samsung logo appears, hold the volume up key to bring up the lock screen display. Then select Safe Mode.
If you can use your mobile device in Safe Mode, it may be that the new firmware has corrupted data in your device's memory. If this is the case, try the following solution to determine if it is an app. Safe Mode disables third-party apps. If apps are triggering the restart loop, this will cure the issue.
Solution 2: Incompatible third party application
Apps that are incompatible with system updates will crash when you try opening. If your Galaxy has stopped restarting automatically in Safe Mode, the problem is most likely because you have an installed app that is incompatible with the new firmware.
To resolve this, you will have to remove your apps or reinstall them whilst you are still in safe mode. The most likely culprit will be one of the apps that were open when you installed the updates.
Solution 3: Cached data stored
If your Samsung Galaxy keeps restarting after rebooting in Safe Mode, the next best option is to try wiping the cache partition. Don’t worry, you will not lose your apps or cause them to malfunction as new data will be cached when you use the app again.
It is important to keep cached data clean for the operating system to run smoothly. However, it can sometimes be the case that existing caches are incompatible with system updates. As a result, files become corrupted. But because the new system is still attempting to access data in the apps, it prompts the Galaxy to keep restarting automatically.
All you have to clean up cached data is follow these simple steps:
• Turn off the device, but whilst doing so, hold the volume button on the “up” end together with the Home and Power buttons.
• When the phone vibrates release the Power button. Keep the other two buttons pressed.
• The Android System Recovery screen will appear. Now you can release the other two buttons.
• Then press the volume “down” key and navigate to the “wipe cache partition.” Once the action is complete the device will reboot.
Did this resolve your problem? If not, try this:
Solution 4: Hardware problem
If your Samsung Galaxy restart loop persists, the problem could be caused by one of the device's hardware components. Perhaps it was not installed properly by the manufacturers, or it has been damaged since leaving the factory.
To check this, you will need to perform a factory reset to determine if the phone is in working condition – especially if this is a new device. However, you should note this action will delete all the personal settings and other data you have stored in the memory – such as passwords.
If you haven’t already backed up your data using the Dr.Fone toolkit - Android Data Extraction(Damaged Device), do that now before performing a factory reset. You might also want to make a note of your various passwords in case you have forgotten them – because as you know, that’s easily done!
How to perform a factory reset if your Samsung Galaxy keeps restarting again and again:
• Turn off the device and press the volume up key, power button, and home button all at once. When the phone vibrates release the power button only. Keep the other two buttons pressed down.
• This action will bring up the Android Recovery screen.
• Use the volume down key to navigate to the “wipe data/factory reset” option then press the power button to confirm your selection.
• You will then get more options. Use the volume down key again and select “delete all user data.” Confirm your selection by pressing the power button.
• You will then be presented with the screen below. Press the power button to select reboot system now.
We hope one of the above solutions resolved your Galaxy restart loop. If not, you will have to contact a qualified technician and possibly return the device to Samsung or the retailer from where you purchased the device.
If the restart issue was resolved, congratulations – you can go back to enjoying your Samsung Galaxy! But before you go, one last word of advice to prevent any problems from happening again.
• Use a protective case
Mobile devices can be pretty robust on the outside, but the inner components are very delicate. They don’t like hard knocks and adverse weather conditions. You can protect the longevity of your mobile phone by using a protective cover – which also keeps it clean and protects it from scuffs and scratches.
• Clean cached data
As we explained above, too much-cached data can impact on the performance of the operating system. It is therefore a good idea to clean the cache now and again, especially if you use apps a lot.
• Verify apps
Whenever you download an app to your Samsung device, verify they are not corrupt or have malicious malware. To do this select the App menu, go to settings, click Section System, and Security. It’s that simple.
• Internet security
Only download apps and files from websites you trust. There are a lot of low-quality sites online that have malicious malware lurking underneath the clickable links.
• Install a trustworthy anti-virus
With cybercrime on the rise, having good anti-virus software produced by a reputable company will help protect your mobile device from being corrupted.
