What to do if your Samsung Galaxy A40 got stuck on Samsung logo

When a smartphone like the Samsung Galaxy A40 got stuck on the Samsung logo and would no longer continue the usual boot process, you can always expect it to be an issue with the firmware. There were owners who complained about this problem shortly after they’ve updated their devices. Others, on the other hand, experienced it after modifying the firmware. 

Had this problem occurred after tampering with the stock firmware, the best thing you can do is reflash the stock ROM. However, if it occurred after an update or if there’s no apparent reason at all, then there’s a greater chance that you’ll be able to fix it by doing some troubleshooting procedures. Continue reading down below as I’ve mapped out a couple of solutions you can use to fix your phone that got stuck on the Samsung logo.

Fixing a Galaxy A40 that got stuck on Samsung logo

If there’s a good thing about this issue, that would be the fact that your phone still powers on. Which means that the hardware must still be working fine. So you can actually focus on troubleshooting the firmware and that’s what we need to do. With that said, here’s how you troubleshoot your phone that got stuck on the Samsung logo…

First solution: Try to boot the phone in Safe mode

It is always possible that an app or some of them has triggered a problem with the firmware that resulted in a problem like this. In such case, you would be able to make your phone boot up into safe mode considering the fact that most of the time, third-party apps are the cause of a problem like this. Here’s how you restart your phone in safe mode using the hardware keys: 

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the 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.

If the boot to safe mode is successful, your phone will display the text ‘Safe mode’ on the lower-left corner of the screen and you should be able to use it normally. If this is the case, then try to create a backup of your important files and data, and then try to reboot the phone into standard mode. 

If booting in standard mode does not go through and your Galaxy A40 still gets stuck on the Samsung logo, then try to start it up in safe mode again, and then perform the factory reset through the Settings menu. 

On the other hand, if your phone couldn’t boot up in safe mode, then move on to the next solution.

Second solution: Start it up in Recovery Mode

If your Galaxy A40 failed to start in Safe mode, then you should try booting it up in Recovery Mode. This mode is considered the fail-safe for Android devices because even if the phone has a serious firmware-related problem, as long as the firmware has not been modified, it should still be able to boot in Recovery mode. Here’s how it’s done on your Galaxy A40: 

  1. Turn off the device.
  2. Press and hold the Volume Up and Power keys.
  3. When the Galaxy A40 logo shows, release all three keys.
  4. Your Galaxy A40 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 

Assuming your phone has reached the black screen with blue texts on it, it means that it has successfully started up in Recovery Mode. In this case, you should do the following to try and fix the problem by wiping the cache partition: 

  1. Press the Volume down key several times to highlight wipe cache partition.
  2. Press Power key to select.
  3. Press the Volume down key to highlight yes, them and press the Power key to select.
  4. When the wipe cache partition is complete, Reboot system now is highlighted.
  5. Press the Power key to restart the device.

If it still won’t continue to boot up after wiping the cache partition, then try to restart it in recovery mode again and then do the factory reset. Here’s how: 

  1. Turn off the device.
  2. Press and hold the Volume Up and Power keys.
  3. When the Galaxy A40 logo shows, release all three keys.
  4. Your Galaxy A40 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Again, as long as the firmware has not been modified, you should still be able to make your phone boot up successfully by doing the master reset through the recovery mode. 

However, if this problem persists even after doing this procedure, then it’s time you brought it back to the store or to a local shop so that a technician can check it up for you.

I hope that this troubleshooting guide has been able to help you determine the reason why a phone like the Samsung Galaxy A40 can get stuck on the Samsung logo.
