Performance issues such as random restarts, system crashes, and boot loops are among the common symptoms of memory errors in mobile devices. These problems usually instigate when the internal memory of the device is running low. In this state, the device would no longer be able to carry out new processes or load services as it normally does when its internal memory is still sufficient. But for as long as the device is free from any sort of hardware damage, such issues can still be remedied by some workarounds. The key to fixing them is by freeing up memory space, like deleting unwanted apps and other complex files that are no longer useful.
Aside from memory issues, there are also other factors that can inflict similar issues to occur on a smartphone. Read on to find out what else can trigger your device to act up and what to do as remedies. The solutions I’ve mapped below can be used to deal with the same issue on the Samsung Galaxy A7 smartphone that keeps rebooting by itself. Feel free to refer to this walkthrough, whenever you need some more inputs as you troubleshoot your device.

How to troubleshoot Galaxy A7 that keeps on rebooting on its own
Before you begin troubleshooting, check and ensure that your phone’s internal memory is not yet full. Your device should have at least 500MB to 1GB memory space to operate normally. If necessary, free up some space by deleting unwanted contents and applications. Move on and troubleshoot software errors, if the memory status is good and yet the device is still acting weird.
First solution: Force restart.
Forcing the device to restart clears any background applications including those that get corrupted. The entire system operation can adversely be affected or halted by errant applications and services. Performing a force restart can rule this out.
- To force restart your Galaxy A7 (2017), press and hold the Volume Down and Power buttons simultaneously for about 10 to 20 seconds and then release both buttons when the device power cycles.
A force restart works the same as the usual device restart or soft reset without affecting any data stored on the internal memory of your phone. It is a simulated battery removal procedure that is recommended to unfreeze and reboot a frozen device.

Second solution: Boot into safe mode.
All third-party apps are temporary disabled when in safe mode, thus making it easier for you to determine if the problem is caused by a downloaded app or not. That said, try booting your device in safe mode and see how it performs. To enable safe mode on your Galaxy A7, simply follow these steps:
- With the device turned on, hold down the Power button until the Samsung menu options appear on the screen.
- Tap Restart from the given options.
- While your device is restarting, press and hold the Volume Down button for several seconds.
- Release the Volume Down button when the phone powers on again.
At this point, you should see the Safe Mode label on the bottom-leftmost corner of the screen. Your phone is now running in safe mode.
Use your device as you normally do while in safe mode then observe its performance. If it does not reboot by itself in this mode, it means a third-party app is the culprit. In that case, try to think of which app you’ve downloaded has caused your device system to go rogue. It must be the one you’ve installed prior to the onset of the problem. To fix the problem, you will need to uninstall the bad apps from your device. If you cannot figure out which app is to blame, then you can try uninstalling apps individually. Don’t forget to test your phone after deleting an app to find out if the problem is fixed or not. You can always reinstall all safe apps later.
To exit Safe Mode, simply restart your phone.
Third solution: Update software to the latest version available.
Software updates also contain fix patches for security enhancements to clear any existing bugs and malware that caused various issues on the device including automatic restarts. To check for available software update, follow these steps:
- Open the Apps menu.
- Tap Settings.
- Tap About device.
- Tap Software update.
- Then select Update Now or Download updates manually.
Typically, you will be prompted with a notification if a new software is available for your device. Before you download and install the update file, your phone must be connected to Wi-Fi Internet, with sufficient battery/power and available memory. Update files may come in big sizes, which means the need to free up more space of the internal memory.
Fourth solution: Wipe cache partition.
Wiping the cache partition can help if the problem is attributed to corrupted temporary data from the system cache partition. It is also recommended to wipe cache partition if your device started to act up after installing new software update. Here’s how to wipe cache partition on your Galaxy A7 2017 smartphone:
- Turn off your phone.
- With your phone turned off, press and hold the Volume Up, Home, and Power buttons simultaneously for about 10 to 20 seconds.
- Release all buttons when the Android system recovery screen appears.
- Press the Volume Down button several times to scroll to and highlight Wipe cache partition from the given options.
- Then press the Power button to confirm selection.
- Wait until your phone is done wiping cache partition and prompts to reboot the system.
- Then press the Power button to trigger a device restart.
Test to see how your phone works after the restart. If the problem continues, then you have to consider opting for system resets.
Fifth solution: Factory reset in Android recovery mode.
You can consider it as a major system issue if it persists after exhausting all prior means and applicable workarounds. Cases like this would already require advanced solutions including a full system wipe out. There might be some tough bugs and malware that inflicted more serious system errors to occur and prevented your device from carrying out normal operations. And this is when a factory reset or master reset is recommended. Doing so will wipe everything out from your phone system including complex bugs and malware. Should you wish to proceed, back up all your important data for safekeeping. Then follow these steps to master reset or factory reset your Galaxy A7 via Android recovery mode:
- Turn off your phone.
- With your phone turned off, press and hold the Volume Up, Home, and Power buttons simultaneously for about 10 to 20 seconds.
- Release all buttons when the Samsung logo appears and the Android system recovery menu is displayed.
- Press the Volume Down button several times to scroll to and highlight Wipe data/Factory reset from the given options.
- Then press the Power button to confirm selection.
- When prompted to confirm wiping all user data, press the Volume Down button to highlight/select Yes — delete all user data.
- Then press the Power button to confirm selection. A factory reset then instigates.
- The Reboot system now option will be highlighted when the reset is finished.
- To reboot your phone, press the Power button.
- After the reboot, you can proceed with the initial device setup.
Software-related issues are usually resolved after performing a master reset or factory data reset on the device. Aside from the fact that the memory is emptied, the phone system is also cleared from any complex bugs and malware. However, your device likely requires service if it is still rebooting by itself after the reset. There is a higher chance that the problem you’re dealing with is attributed to hardware damage.
Other options
Take your device to a service center if the none of the prior methods is able to fix the problem and your Galaxy A7 still reboots by itself. There might be some sort of physical or liquid damage on the phone components that needed some repair.
