Problem: the fingerprint sensor does not work

Many people have discovered that the fingerprint sensor of their P20 Pro has stopped working. We have seen threads on the subject in the XDA developer forum and Reddit, among others. For most people, it seems that it does not respond, but others also noticed that the sensor was warming up and that the fingerprint sensor options in the menu of Configuration You become inaccessible.

  • Try to access Settings> Security and privacy> Fingerprint ID. You will have to enter your PIN and then try to add a New fingerprint.
  • If you cannot access the settings, try to reset the factory settings, but be sure to make a backup of everything, as this will erase your phone completely. Once you've made a backup, go to Settings> System> Reset> Factory data reset> Phone reset.
  • If the problem persists after a factory reset, it could be a hardware failure. You should contact your supplier, retailer or Huawei to obtain information about a repair.

Problem: push notifications do not work

Some people have had problems with push notifications, either with a new WhatsApp message or an incoming Outlook email, and it doesn't work as it should. When the P20 Pro is on standby, with the screen off, notifications appear to stop and then appear when the phone is lifted and unlocked again. There is a thread about it in the XDA developer forum. This is probably due to the configuration on your P20 Pro and is easy to fix.

Possible solutions:

  • To start, go to Settings> Battery> Ms (gear icon in the upper right) and make sure of the Keep Wi-Fi on is set to Always, like Activate mobile data.
  • Look in Settings> Applications and notifications> Applications> Settings> Special access> Ignore battery optimization and select any application you have problems with.
  • Go to Settings> Battery> Application start and alternate any application with which you have problems to manage it manually.
  • Search in Settings> Wireless connections and networks> Mobile data or Data usage and make sure the data saver is disabled.

Problem: random restart

There are several comments on the forum XDA Developers of users who express their disagreement, for having to be victims of unanticipated reboots of their Huawei P20 Pro. One of the people, said that this happened repeatedly when he was in the Galera application, but for others it seems to be a bit more random when it happens Apparently, the P20 Pro shuts down and restarts suddenly, with no apparent cause.

Possible solutions:

  • Try to erase the cache partition to start. Turn off your Huawei P20 Pro by pressing and holding the power key and then touch To turn off. Once it has turned off, press and hold the Switched on and Turn up the volume until you see the Huawei logo. Then release the Switched on, but hold down the Raise the volume until you see the IEMU on the screen. You can use Volume down to highlight Remove cache partition (Wipe cache partition) and the Switched on to select it When you're done, use Turn up the volume to highlight Reboot system now and the key Switched on to select it
  • If the restart problem persists after this, it is possible that the culprit is an application or configuration. The easiest way to test this hypothesis is to restore the factory phone. Make a backup of everything first, then go to Settings> System> Reset> Factory data reset> Phone reset> Phone reset. When you're done, try setting up your phone as new instead of restoring the backup, to see if the reboot problem comes back. If it is not, you can begin reinstalling applications selectively, monitoring the recurrence of the restart problem.
  • If you perform a factory reset and set the Huawei P20 Pro as new and still restart unexpectedly, then it is time to contact Huawei, or your supplier.

Problem: very fast battery wear

We are impressed by the battery life of the Huawei P20 Pro, since it is 4000 mAh. This means that it should easily last a day and a half to two full days. However, some users have reflected in the forum of XDA Developers and in the Android Central forum about the disappointing performance of the battery.

Know what our suggestions are to be able to take full advantage of the battery of your Huawei P20 Pro to the fullest.

Solutions:

  • You can go to Settings> Battery and activate the energy saving mode or the Ultra energy saving mode. However, it is important that you know that, when choosing this option, some background operations will not work and decrease performance.
  • You can save some battery life by going to Settings> Security> Screen lock and passwords and alternating Always show information.
  • You can also consider going to Settings> Battery to toggle between the darker interface colors.
  • Take a look at Settings> Battery> Application start and consider adjusting some settings to save energy.
  • Go to Settings> Screen and change the screen resolution from FHD + to HD + or set it to Intelligent.
  • Set the Suspend setting to Settings> Show as low I can tolerate.

Possible solutions:

  • First, make a backup of everything, then go to Settings> System> Reset> Factory data reset> Phone reset> Phone reset. If you restore a backup after the restart and the problem comes back, try to factory reset and set the phone as new. It is possible that a configuration or application in the backup is causing the problem.

Problem: touch screen delays

We have seen a couple of posts, especially in the forum of XDA Developers about delays on the touch screen or when people move or try to make small and precise movements on the screen.

Possible solutions:

  • Some users have suggested going to Settings> Smart assistance> Motion control to activate things like smart screen capture. It is possible that these gestures are adjusting the touch screen response. You should also make sure that the mode Gloves is deactivated in Settings> Smart Assistance.
  • Some people say that a software update solved the problem. Enter to System update settings> Check for updates and see if there is a software update available.

Solutions:

  • Try to go to Settings> Screen and change the screen resolution from FHD + to HD + to see if that makes any difference.

Problem: slow charge

Huawei's SuperCharge system can take the battery from zero to completely full in about 90 minutes, but some people have had trouble getting fast charging speeds. There are a couple of topics in the XDA Developers forum about this.

Possible solutions:

  • Make sure you are using the cable and charger that came with your Huawei P20 Pro and that you are connecting it to a working outlet.
  • If your Huawei P20 Pro gets wet, then it may be limiting the charging speed as a form of security. Just wait for it to dry or place it in a cup full of raw rice to extract moisture. Then try again.
  • If the problem persists, contact Huawei, your supplier or seller.

Problem: the microphone does not work properly

We have seen some people who claim that the telephone's microphone does not work properly, since they have realized that when they make a call, the other person cannot hear them and the same happens when recording audio or video messages. But don't worry, there are some options to solve the problem, according to the XDA Developers forum.

Solutions:

  • Press and hold the button Switched on and touches Restart. This seems to work at least temporarily for most people. It is possible that the problem is caused by the use of private space, the use of the USB-C headset adapter or the use of Bluetooth for audio, so you may want to restart after any of these activities.
  • If you have an application that uses the microphone, consider removing the permission from the microphone or uninstalling it and testing to see if that solves the problem. You can check through Settings> Applications and notifications> Permissions.

Possible solution:

Hopefully, this is just a software error and be corrected. Enter to System update settings> Check for updates and see if there is a software update available. You may also want to open Play Store, touch the cone of the three horizontal lines (known as the hamburger) located in the upper left and press My apps and games> Update all.
