The Apple HomePod is a beautiful and technically mature speaker for playing music such as Apple Music, AirPlay or Spotify.

In addition, the Apple HomePod has a cool feature on board: the listening history

This is used to create music recommendations for the user. The problem with this is that when several people in the household use the Apple HomePod, different music genres are suggested.

Everything is possible, from radio plays for children to hip hop and techno. Depending on what the individual person likes to hear about the Apple HomePod at home.

Here it is then recommended to deactivate the hearing history on the Apple HomePod. How to do this is explained below:

1. Open the Home App on an iPhone or iPad.

2. Briefly place your finger on the Apple HomePod.

3. In the Home app on the iPhone, select Settings on the lower right

4. As the fourth menu item you will see "music & podcasts"

5. Here you can now deactivate "use hearing history".

You have just successfully deactivated the hearing history on your Apple HomePod.

You will no longer receive any hearing suggestions based on the music you have already listened to.

For many users, the following technical feature is important when deciding on a new smartphone: rSAP.

This is the so-called "Remote Sim Access Profile". This can be accessed, for example, by a car with an integrated telephone module.

Then only the Sim card of the Huawei P20 Pro is used. Mobile phone reception etc. is provided by the car phone.

The advantage of rSAP is that you have better reception in a vehicle, as the antenna is usually mounted on the outside of the car. Vehicles from Mercedes, VW, Audi, Porsche etc. sometimes use rSAp for their hands-free kits.

Does the Huawei P20 Pro support the rSAP mode? Since the Huawei P20 Pro is a dual SIM smartphone, rSAP is unfortunately not supported.

So if you can't live without this feature, the Huawei P20 Pro probably won't be shortlisted.

The Windows 10 operating system has an integrated spell checker, also known as auto correction. This can automatically correct misspelled words in the search, data fields etc.

• Correct spelling mistakes
• Automatically Highlight spelling mistakes

Then words are no longer automatically corrected by Windows 10.

You may see that your smartphone or tablet is not certified in the Google Play Store. You're probably wondering: What's the Google Play Store certification all about?

How can I still download apps? We'd like to give you some advice on how to proceed if the certification is not available within the Google Play Store.

Google denies non-certified Android devices access to Google Play Store apps and services. For example, non-certified devices can be counterfeits or smartphones running an Android Custom ROM.

Custom Roms can be used after the smartphone has been reported to Google. If you do not agree with this, an error in the Google Play Store app can also be responsible for your smartphone not being displayed as certified.

Often the following tip helps:

1. Open the settings on your Android smartphone

2. Select Apps and Notifications (depending on the manufacturer) from

3. Open the "Google Play Store" app info

4. Select "Memory" from

5. Now tap the following buttons:

• Delete cache
• Delete data

Your smartphone should then be displayed as certified when you reopen the Google Play Store.

Now you know what you need to know about "Google Play Store certification? Device not certified" and what the cause is.
