The Huawei P20 Pro is usually protected by a lock screen, which is designed to prevent unauthorized persons from accessing data stored on the phone.

The lock screen is usually secured by a pin, password, pattern, or fingerprint. However, apart from the fingerprint, you can also forget the unlocking method.

This can be quite annoying, because you can no longer access your data and have been bypassed by the protection mechanism.

So what can you do if you have forgotten the Lock Screen unlocking method on the Huawei P20 Pro? Below we have listed the available options and explained them in detail.

Depending on how your Huawei P20 Pro is configured, there may be problems with your data.

Use Android Device Manager to unlock the Huawei P20 Pro - no data loss

To do this, please open the following website on a PC, Smartphone or Tablet:

• Android Device Manager

You will now need to enter your Gmail account password, with which your Huawei P20 Pro is synchronized.

Your smartphone will now be localized by the Android Device Manager. The prerequisite for this is that the Huawei P20 Pro has an Internet connection via W-Lan or mobile Internet.

Localization may take a few minutes now. Then select "Lock" in the Android device manager. You will now need to set a new password to lock the Huawei P20 Pro screen. After you have performed this procedure, you can now enter the password you have just set on your Huawei P20 Pro.

The device is unlocked. A new lock type can then be assigned.

Samsung Smart Switch Backup or backups from the cloud - data loss possible

Another possibility is to import a backup via the HiCare software. However, this usually only works if you regularly create backups using this software, for example on your computer, and at this point you are still familiar with the specified unlock method.

To restore the backup, simply use the HiCare software on your PC to restore the backup. Depending on how old the backup is, data may be lost!

Reset to factory settings - Factory reset - Data loss very high

The last option you have is to reset the Huawei P20 Pro to factory settings. When a factory reset is performed, all data on the Huawei P20 Pro is deleted and the Huawei P20 Pro or Android system can then be set up again.

This method should be used as a last resort, because the loss of data is considerable if you have not made any backups of the memory.

Proceed as follows to reset the factory on the Huawei P20 pro:

1. To do this, first switch off the smartphone and then follow these steps:

2. To switch on the device, press the following keys simultaneously:

Then select "Restart now". Your Huawei P20 Pro will now reset to factory settings.

As with variant 2, you can then try to import backup data from the Huawei Cloud or via HiCare. This variant, too, is usually associated with data loss.

If possible, we recommend you to choose variant no. 1, because you can unlock the Huawei P20 Pro very easily without losing any data.

If possible, we recommend you to choose variant no. 1, because you can unlock the Samsung Galaxy S9 very easily without losing any data.

When you listen to music or sounds through the Huawei P20 Pro's speaker, the music may be quiet, dull, or muffled. Often the following cause can be cited:

The speaker outputs of the Huawei P20 Pro are clogged with dirt, dust or dirt.

If you often carry the Huawei P20 Pro in your trouser or handbag, dust particles or dirt can clog the speaker output.

You must therefore clean the speaker output.

The best way to do this is as follows:

Tip 1: Take a vacuum cleaner and try to remove the dust with it.

Tip 2: Use a pointed object such as a toothpick and try to remove the dust on the edge.

Tip 3: The Huawei P20 Pro is IP67 protected against water ingress. Place the smartphone in a low water basin and leave it there for about 30 seconds. Dry the appliance and then use the vacuum cleaner again.

These cleaning processes will result in the loudspeaker being free again and the sound being able to escape unhindered.

The sound experience should then be much better with your Huawei P20 Pro.
