How to fix Galaxy A80 keeps rebooting by itself | A80 reboots randomly

If your Galaxy A80 keeps randomly rebooting, there’s a number of troubleshooting steps that you can do to know where the problem is coming from. Follow our solutions below to fix the issue.

Galaxy A80 reboots randomly fix #1: Charge device

If you have Galaxy A80 reboots randomly issue, the very first thing that you want to do is to check if it needs to be recharged. At times, low battery power level may cause this kind of problem to try to top up the battery until it reaches at least 90%. Also, you want to look out for signs of possible power issues like sudden drop in battery level on standby, overheating, or fast battery drain. If you have any or all of these indicators while also experiencing random reboot, it’s possible that the battery may not be working properly. 

If the Galaxy A80 still reboots at random even when fully or partially charged, proceed to the next troubleshooting steps below.

Galaxy A80 reboots randomly fix #2: Check for overheating

If your Galaxy A80 keeps rebooting and getting warm to touch at the same time, overheating may be to blame. Android devices are designed to shut down on their own if internal temperature reaches a certain point to prevent damaging the system.

Overheating by itself is usually not the problem but just another sign of a deeper issue. It can be caused by a bad app, malware, software glitch, or hardware trouble. You should continue to troubleshoot the device if it’s overheating.

Keep in mind that running devices can get warm without actually overheating. Running smartphones generates heat so don’t be so quick to point a finger to overheating. If your device gets too warm that you can no longer hold it normally, it’s probably overheating.

Galaxy A80 reboots randomly fix #3: Soft reset

Sometimes, minor bugs may develop after a device is left to run for a long time. It’s recommended that you restart your device at least once a week to prevent issues from bugs of this type. As a troubleshooting step in this situation, you want to ensure that you’ve rebooted the device. Try restarting it normally first by pressing the Power button to access the boot menu. Then, select Restart option and see if that works.

Another way to restart the device is by pressing and holding the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on. This simulates the effect of having disconnected the battery from the device. If this works, this may unlock the device.

If doing the regular restart won’t help, then try this:

  1. Press and hold the Volume Down button first and don’t release it.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more. 
  4. The second restart procedure tries to simulate the effects of removing the battery pack. On older devices, disconnecting the battery is often an effective way in fixing unresponsive devices. If nothing changed though, proceed to the next suggestions.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

  1. Open Settings app.
  2. Tap Device Care.
  3. Tap the 3-dot at the top.
  4. Select Auto restart. 

Galaxy A80 reboots randomly fix #4: Refresh system cache

If your Galaxy A80 reboots randomly after installing a system update, there may be a problem with the system cache. If this cache gets corrupted or outdated, there might be all sorts of bugs that can develop. For some, the issue may be minor while others may experience more severe cases. To ensure that your system cache is in good shape, you can follow these steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Galaxy A80 reboots randomly fix #5: Install software and app updates

If you’re still able to access the settings menu on your device, try to see if there’s pending update for the system before the device reboots again. You can go under Settings > Software update. By default, you should receive notifications if there’s a pending software update. If you happen to disable this automated system, make sure to manually check for updates under Settings. 

For your apps, we suggest that you also manually check for updates via Google Play Store. Some Samsung apps can only be updated individually so be sure to go under each of their settings menu and check for updates. For example, updating Gallery app for Samsung Galaxy devices require that you go under app’s settings > About Gallery.

If you have apps taken outside the Play Store or Samsung Galaxy store, then you must ensure that they are compatible and updated.

Galaxy A80 reboots randomly fix #6: Check for bad apps

In some other cases, an issue like this may be caused by a bad or poorly coded application. If your Galaxy A80 reboots randomly after a new app was installed, try to delete that app. If you can’t recall which app was installed, you have to restart your phone to Safe Mode. This is a different software environment originally used by Samsung technicians to check for rogue third party apps. In this mode, only preinstalled apps will be allowed to run. So, if the problem goes away when you reboot the phone to safe mode, that’s an indicator that you have a third party app problem.

To restart your device to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Check for the problem by using the device for several hours.

If your phone won’t reboot on its own on safe mode, that means there’s an app that affects Android. To identify which of your apps is the source of trouble, you must use elimination method. Here’s what you can do:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Galaxy A80 is still problematic, repeat steps 1-4.

Galaxy A80 reboots randomly fix #7: Erase device

You must wipe your device with factory reset if none of the solutions have worked. Factory reset is an effective way to solve all sorts of software problems. If the cause of the issue is coming from unknown software or app bug, hard reset or factory reset should help. Be sure to create a backup of your personal data before you do it.

To factory reset your phone:

Method 1: How to hard reset on Samsung Galaxy S10 via Settings Menu

  3. Scroll to and tap General management.
  4. Tap Reset.

  6. Read the information then tap Reset to continue.
  7. Tap Delete All to confirm action.

Method 2: How to hard reset on Samsung Galaxy S10 using hardware buttons

  1. If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
  2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
  3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  4. Press and hold the Volume Up button and the Bixby button at the same time.
  5. While still holding the Volume Up and Bixby keys, press and hold the Power button.
  6. The Recovery screen menu will now appear. When you see this, release the buttons.
  7. Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
  8. Press the Power button to select ‘Wipe data/factory reset.’
