It may happen that on the Huawei P20 Pro an info is displayed in the notification bar at the top of the screen with "Not registered on the net". If you see this message, it means that you cannot make phone calls or surf the mobile Internet.

This condition is of course unacceptable for a mobile phone and therefore we will show you here how you can hopefully solve the problem.

You now have the following options to solve the problem on the Huawei P20 Pro:

Sim card inserted correctly?

It can happen that the Sim card has slipped due to a shock. If the card has no contact, this leads to the error in the status bar "Not registered in the network".

Sim card defective?

Test if the same phenomenon occurs with another Sim card. If not, your Sim card may be defective.

Activate the network mode "GSM" on your Huawei P20 Pro

Open the Android system settings on your Huawei P20 Pro. From here, go to "Wireless & Networks" and then to "Mobile Network". In this submenu you can now see "Preferred network type". Select the entry.

Now a menu appears, in which various options or connection modes are available. Now select "Only 2G" - Done!

Often it helps to go outdoors with the Huawei P20 Pro to get a network signal and make calls. To speed up the network search, it is often also helpful to restart the Android smartphone briefly.

Unfortunately there is no other way to solve the problem with "Not registered in the network". Under certain circumstances you should ask your network provider if an error occurs in the network.

We hope that you will now be able to use your Android smartphone again and perhaps even use the mobile Internet.

Can I use the Samsung Galaxy S8 to take photos with Bokeh effect? You might ask yourself this question if you are faced with the choice of buying the Samsung Galaxy S8 instead of the Samsung Galaxy S9 Plus.

The Samsung Galaxy S8 doesn't have a bokeh function directly integrated, but you can achieve such an effect by using the aperture function in the camera app.

How this works on the Samsung Galaxy S8 is explained in the following:

Samsung Galaxy S8 Create Bokeh Effect with Aperture

1. Open the camera app on the Samsung Galaxy S9

2. Switch to the camera mode "Aperture" and then tap the aperture symbol on

3. Choose the largest possible aperture value, because the larger the aperture, the blurrier the background and the more objects or people in the foreground are emphasized.

Now you have achieved a bokeh effect on the Samsung Galaxy S8. This is probably not as effective as the portrait mode of the S9 Plus, but the S8 is also much cheaper.

You can also install apps from the Google Play Store that have such a bokeh mode.

Unlike the Samsung Galaxy S9, the Samsung Galaxy S9 Plus has a special Bokeh mode integrated in the camera app, with which you can make the foreground sharp, the background blurry.

This camera mode is especially popular for portraits of people, because the person is highlighted. The Bokeh effect of the Samsung Galaxy S9 Plus is achieved by using both cameras.

How to use Bokeh effect of the Samsung Galaxy S9 Plus

1. Open the camera app.

2. Select "Portrait Mode".

3. Take a photo with the Samsung Galaxy S9 Plus.

Now you should have taken a nice photo with Bokeh effect.

Of course, this can be edited later in the app, such as adjusting contrast, saturation and color.

Now you know how to take a photo with a bokeh effect on the Samsung Galaxy S9 Plus.

If you want to take a photo with Bokeh effect with the Samsung Galaxy S9 camera, you won't find any suitable camera modes.

However, with the Samsung Galaxy S9 you can of course take Bokeh portraits. We'll tell you exactly how this works here:

The Bokeh effect is created via the aperture if there are no two cameras like the S9 Plus.

To do this, proceed as follows:

1. Open the camera app on the Samsung Galaxy S9

2. Switch to the camera mode "Pro" and then tap the aperture symbol at

3. Select the largest possible aperture value, because the larger the aperture, the blurrier the background and the more emphasis is placed on the objects or people in the foreground.

Because the Samsung Galaxy S9 has a mechanical aperture, this method is very suitable for achieving a bokeh effect.

The slightly larger Samsung Galaxy S9 Plus, which is equipped with two cameras, even has its own portrait mode, which the "normal" S9 unfortunately doesn't have.

You now know how to shoot photos with Bokeh effect with the Samsung Galaxy S9 without having to install an extra app.

On your Huawei P20 Pro, you may see a heart shaped symbol in the status bar to the left of the Notch. This heart symbol comes from the "Health" app, which is factory installed on your smartphone.

You can use it to track your steps, count calories and much more. The heart symbol therefore comes from the Health App and gives you information about the steps taken and the calories consumed.

If you don't need this information in the status bar of your Huawei P20 Pro, you probably want to deactivate it.

Below we describe how you can deactivate the heart symbol in the status bar on the Huawei P20 Pro.

Hide heart symbol in the status bar of the Huawei P20 Pro
