Random restart is among the common indicators of performance issues in mobile devices, particularly attributed to memory problems like when a phone’s internal memory is running low. If the problem occurs to new high-end devices, it’s likely inflicted by software errors especially if occurring suddenly. But if the same symptom emerged from a previous instance of dropping or liquid exposure on the device, then there’s a higher chance that it’s a hardware damage. Before rushing to a service center though, you may attempt to resolve the issue and rule out software errors by performing some applicable workarounds.
To give you extra inputs, I have mapped out an easy guide for you to refer to. These are generic procedures and suggested workarounds that are used to deal with an issue on random reboot on a Samsung Galaxy A6 2018 smartphone. Feel free to refer to this walkthrough when needed.

How to troubleshoot Galaxy A6 2018 that keeps rebooting
Before you troubleshoot software issues that might have triggered your device to restart by itself, remove the SD card. Some Android phone users who have dealt with the same issue later found out a corrupted SD card as the trigger. This can happen when any of the SD card files embed some malware or virus, causing the card to become corrupted. Eventually this can adversely affect overall system functions of the phone. If your phone is still acting the same even without an SD card inserted, then the problem is not attributed to a faulty SD card. At this point, you can begin troubleshooting and rule out software errors from the underlying causes.
First solution: Check and manage internal memory.
As mentioned earlier, your device may be acting up because it’s running low on memory or storage space. To check and see if this is really the trigger, check the available memory space of your Galaxy A6 2018 with these steps:
- Tap the Apps Drawer from the Home screen.
- Select Settings.
- Scroll to and tap Storage.
- Read and review the Storage details. Check how much storage is left on your device.
If the available storage is less than 1GB, then you’ll need to free up some space of your phone’s internal memory by deleting old and unnecessary contents like apps, SMS or MMS message, audio files, photos, and other multimedia contents that you are no longer useful.
After freeing up space on the internal memory, restart your device to dump cached files as well.
Second solution: Clear apps and cache/data on your Galaxy A6 2018.
Cached files can also trigger your device to misbehave especially when they become corrupted. This is why regular clearing of cache and data is recommended. You can clear cache and data from an app or wipe cache partition on your device. Before you wipe the cache partition, try clearing recent or background apps on your device.
To do so, open the Recent Apps menu on your phone to show a list of recently used apps that aren’t closed. Then swipe up on an app’s previous to close it.
After clearing recent/background apps, wipe cache partition on your Galaxy A6 2018 with these steps:
- Turn off the phone completely.
- Then press and hold the Power, Home, and Volume Up buttons simultaneously for a few seconds and then release the Power button when the Samsung logo appears.
- Keep holding the remaining buttons until the Android screen shows up then release.
- When in Android Recovery, press the Volume Down button repeatedly to highlight Wipe Cache Partition option.
- Then press the Power button to confirm selection.
- Wait until the cache partition clearing process is finished and you’ll see the Reboot system now option highlighted.
- Press the Power button to reboot your phone.
Your phone will then restart.
Third solution: Update device software to the latest version available.
Installing the latest software version for your phone may also be the potential solution if the problem is inflicted by some software bugs. Updates also offer fix patches to clear any bugs that caused various issues on a device. To check for and install new software update on your Galaxy A6 2018, follow these steps:
- Open the Apps Drawer (Main Menu).
- Tap Settings.
- Tap About phone.
- Tap Software updates.
- Then tap Check for Updates.
- If a new software version is available for your device, you will see a notification with the option to Download now.
- Back up all your important data, if necessary and then tap Download now to start downloading the update file.
- When the download is finish, tap on Install update.
Before you download the update, make sure your phone has sufficient battery (at least 50 percent) and storage space. Wi-Fi or cellular data connection is also necessary as you will be downloading update via OTA.
Follow the rest of the onscreen instructions to complete the update download and installation processes, then see if the problem is resolved.
Fourth solution: Enable safe mode then diagnose apps.
Booting into safe mode can help you determine whether or not the problem is caused by a third-party app. Only built-in apps are allowed to run in safe mode. Hence, if your phone does not reboot by itself while in safe mode, you can say that a third-party app is to blame. Here’s how to enable safe mode on your Galaxy A6 2018:
- While your phone is on, press and hold the Power button for a few seconds until the Power off menu appears.
- Hold on the Power off option until the Restart in safe mode appears.
- Select OK and then wait for a few seconds until your device boots up in safe mode.
You will know when your device is already running in safe mode if you see Safe Mode on the bottom right-corner of the screen. If the problem persists even when in safe mode, then you may have to consider resorting to a full system restore.
Fifth solution: Restore your Galaxy A6 2018 to its factory defaults (master reset).
A factory reset or master reset can be regarded among the last resorts if nothing else works and that your phone is still restarting randomly. There might be some tough bugs causing complex errors and therefore requires advanced solutions. This reset however will lead to data loss because everything will be wiped out in the process. Should you wish to proceed, back up all your important files beforehand. Then continue with these steps:
- Turn off your phone completely by pressing the Power button until the phone shuts down.
- Then simultaneously press and hold both the Volume Up and Power buttons for a few seconds.
- Release both buttons when the Samsung logo appears.
- Tap on the screen as soon as you see the Android bot image with No Command. The Android Recovery menu will then show up.
- Press the Volume Down button several times to highlight Wipe data/Factory reset option.
- Then press the Power button to confirm.
- Press the Volume Down button again to highlight Yes then confirm by pressing the Power button. After a few seconds, you will see the Android Recovery menu with Reboot system now option highlighted.
- Finally, press the Power button to restart your phone.
Alternatively, you can factory reset your Galaxy A6 2018 via Settings menu. Here’s how:
- Open the Apps drawer then tap Settings.
- Go to Cloud and accounts.
- To backup important files before resetting, tap Backup and restore then enable/disable Back up my data and Restore options respectively.
- Go back Settings when the backup is finished.
- Then tap General management.
- Tap Reset.
- Select Factory data reset then Reset device.
- If prompted, enter your PIN or password to continue.
- Then tap Delete all to confirm.
Both these reset methods wipe everything from your phone system including any tough bugs, viruses, and malware that might have caused your device to act up. This therefore resolves random reboot issue on your Galaxy A6 2018 unless a faulty hardware component is to blame.
If the problem continues after performing all applicable solutions, then service would be your next best option. There might be some sort of physical or liquid damage on certain hardware components of your Galaxy A6 2018 smartphone, which therefore requires repair. You can take it to the nearest Samsung service center in your place, so it can be thoroughly diagnosed by an authorized technician.
