How To Fix Samsung Galaxy A6 Randomly Crashing And Rebooting

Problem: I have a Samsung Galaxy A6. It worked absolutely brilliantly for 3 and a half months but about a month ago it began randomly crashing/rebooting – with no discernible cause or pattern. It became progressively worse, sometimes getting locked into a never-ending reboot cycle. Doesn’t appear linked to any particular app. or activity. It came from a company in Hong Kong but its a genuine Samsung. I have (repeatedly) done a full wipe data/hard factory reset and wiped the cache partition. Even without ANY further apps installed it reboots. I have connected the phone to a charger while using it but it still reboots. Occasionally after 15 minutes or more of rebooting (only getting as far as first Android logo) it may actually reach the start up screen and I can go through the set-up process, but it is crashing and rebooting periodically throughout this. It has a 128Gb SD card. I’ve removed the SD card. I contacted Samsung – they simply suggested all the standard resets and wipes. I took it to a local repair centre – seemed like bright young guys. They “installed a fresh OS” and thought it was fixed but it is unchanged – constantly rebooting. Do you have any suggestions? I was thinking to get a new battery. The battery holds its charge well but could the battery itself have developed some software glitch? I’ve looked at a number of forums and there seem to be a lot of people experiencing this issue. Any help/guidance would be much appreciated. Thanks.

Solution: Before performing any troubleshooting steps on this device it’s best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.


One of the main factors that can cause a phone to constantly crash and reboot is a software glitch which we will be troubleshooting right now. Once we have eliminated this possibility then it’s safe to assume that the problem is already caused by a faulty hardware component in which case further checking must be done at a service center.

The first thing you will want to do in this case is to make sure that the phone is fully charged. You should also remove the microSD card of the device as this can usually contribute to the problem especially if it has some corrupted sectors.

Check if the problem occurs in Safe Mode

The first thing you will want to do is to check if the problem is caused by an app you downloaded. This can be done by starting the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Turn the device off.
  • Press and hold the Power key past the screen with the device name.
  • When ‘SAMSUNG’ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see ‘Safe Mode’.

If the phone does not randomly crash or restart in this mode then the problem could be caused by one of the apps you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

There are cases when the cached data stored in a special partition of the phone becomes corrupted. Once the data becomes corrupted this can cause issues with the device such as the one you are experiencing right now. To check if this is what’s causing the problem you should wipe the cache partition of the phone.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key.
  • 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).
  • Press the Volume down key several times key to highlight ‘wipe cache partition’.
  • Press the Power key to select.
  • Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

Perform a factory reset

The last troubleshooting step you will have to do if the above steps fails to fix the problem is a factory reset. This will revert the phone back to its original factory condition. Make sure to backup your phone data before doing this step.

  • Make sure that the phone is off.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key
  • 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).
  • Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

In case the above steps fails to fix the problem then this is most likely caused by a faulty hardware component already. To determine the specific component that is failing to work you will need to have the phone checked at a service center.
