How To Fix Huawei P20 Pro Restarts When Using Camera

Problem: Hi! About a month ago I bought a Huawei P20 pro. At first there didn’t seem to be anything wrong with it. Then, when I was using the camera, it rebooted. I figured power must be too low, so I charged it and it was fine again. Then the problem gradually got worse. Now, when the battery percentage is below 60%, and I use the camera it reboots and doesn’t get past the blue Huawei screen. After a while it shows the EMUI recovery screen, where I can successfully run the recovery. After that I still can’t reboot the phone. At first I thought the problem was my camera, but when I use the camera function in whatsapp, it usually doesn’t reboot, and sometimes when I’m browsing the picture gallery it reboots. The only thing that gets me past the reboot screen, is recharging. Then it works fine and seems fine afterwards. Until I want to take a picture and the whole thing starts again. Because problems only seem to occur when the battery percentage is below 60%, I thought the percentage must be wrong. But, if I don’t do anything ‘picture related’ my phone is absolutely fine and the battery percentage can go below 10% before I have to recharge.

Also, from the EMUI screen I can still download the recovery package and run it. Only when I try to reboot it afterwards it can’t get past the Huawei logo again, unless I plug it in. Steps I’ve already taken:


  • Wipe cache partition
  • Factory reset
  • Removing sd-card
  • Run the Huawei eRecovery


I’ve also tried to enter safe mode, but since I couldn’t get past the Huawei logo, this wasn’t successful.

Solution: Before doing any troubleshooting on the phone its best to make sure that you have the latest software version. If an update is available then I suggest that you install it in your phone. For this particular issue we will check if any software related glitches is causing this problem a this  is usually the easiest to perform.

Fully charge the phone battery

Connect the phone to its wall charger then charge the device until it reaches 100%. When the status indicator is solid green then this means that the battery is fully charged.

Start the P20 Pro in Safe Mode

There are instances when an app you downloaded can cause issues with the device. You might have recently downloaded an app that interferes with the camera operation. To check if this is the case you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Turn off the phone
  • Turn on the phone
  • As soon as you see the Huawei logo on the screen start clicking on the volume DOWN button repeatedly
  • When on you will see the Safe Mode on the bottom left all none pre-installed apps having the android logo are not operational.

If the issue does not occur in this mode then the problem is most likely caused by an app you downloaded. Find out what app this is and uninstall it.

Perform a factory reset on the P20 Pro

In case the issue occurs in Safe Mode then the next step is to check if the problem is caused by a software glitch. You will need to perform a factory reset. This will revert the phone back to its original factory condition. Take note that this will erase your phone data so make sure to create a backup copy before proceeding with this step.

  • Go to the Start screen.
  • Tap Settings.
  • Scroll down then tap System.
  • Tap Reset
  • Tap Factory data reset.
  • All data and settings saved on the Huawei P20 Pro will be deleted. The Huawei P20 Pro will automatically reset and reboot.
  • The Huawei P20 Pro has been reset.

In case the issue still persists even after performing the steps listed above then it’s very likely that this is already caused by a faulty hardware component, possibly the battery failing to work properly. The best thing to do right now is to bring the phone to a service center and have it checked.
