1. Open the settings

2. Navigate to "General" and then to "Save & Reset"

Sometimes you may need to reinstall Instagram because, for example, you are switching to a new smartphone or Android or iOS smartphones are not working properly and you need to reset them to factory defaults.

The question you ask yourself as an Instagram user is, can I simply uninstall and reinstall Instagram without losing data like pictures and videos?

Or do I need to create a backup?

The answer is:

No, there is no need to create a backup when reinstalling Instagram. Because your data such as images and videos are all stored in the Instagram cloud or its servers.

This means you can easily uninstall and reinstall Instagram without losing any of your data.

One of the fastest ways to transfer data between two smartphones is Wi-Fi Direct. This method uses the W-Lan connection to exchange data between your Huawei P20 Pro and another smartphone such as a Samsung Galaxy.

Now you may want to send data from a Samsung Galaxy or another Android smartphone via Wi-Fi Direct to the Huawei P20 Pro, but it has problems receiving the data.

If your Huawei P20 Pro also has problems receiving data such as pictures, videos, etc. via Wi-Fi Direct, please use the following tip to fix the problem:

1. Before you can send a file to the Huawei P20 Pro from another smartphone, you must first send a file from your Huawei P20 Pro to the device. Sounds strange, but that's how it sounds.

2. Simply send a photo of your Huawei P20 Pro to the device, which would like to send you a file afterwards. Open the gallery and then the photo you want to send. Then select "Share" and "Wifi Direct". Done!

The other smartphone, for example a Samsung Galaxy must accept now only this file. Done!

3. This has now caused that your Huawei P20 Pro can finally receive files from this other smartphone.

Now send the data from your Samsung Galaxy via Wi-Fi Direct to the Huawei P20 Pro.

Note: It can take up to 20 seconds for the Wi-Fi Direct acceptance message to appear on your Huawei P20 Pro.

Now you know what to do if your Huawei P20 Pro cannot receive files via Wi-Fi Direct.

On the Huawei P20 Pro you can connect to a W-Lan network via W-Lan and then surf the Internet. Each HotSpot is stored in a network list, so you can quickly log back in without having to re-enter your credentials.

Over time, however, a lot of W-Lan networks will accumulate in this network list, which you will never use again.

Especially if you often dial in to different W-Lan hotspots during your holidays, then these are useless for a further permanent use in the list of networks.

If you would like to delete individual networks from the W-Lan network list, please proceed as follows:

1. Open the settings on the Huawei P20 Pro

2. Open "Wireless & Networks"

3. Open "WLAN" and activate it if not already done

4. At the bottom of the menu box, please select "Configure"

5. You will now see the entry "Saved networks" - Tap on the entry

6. You will now see all networks you have ever connected to with the Huawei P20 Pro - Press and hold the finger on an entry you want to remove

7. Then select the "Remove" button.

Now proceed as follows with all W-Lan networks that you want to delete from the list.

You now know how to remove individual W-Lan networks from the list of stored Wi-Fi networks of the Huawei P20 Pro.
