1. Check the phone settings: Make sure that your Huawei phone is allowed to install applications from unknown sources. In the phone settings, find the "security" or "privacy" settings, and then turn on the "Allow installation of unknown sources" option.
2. Download the APK file: If you can't find the potato software in the app store, you can try to search and download the APK file of the app online. Note that downloading APK files from unofficial or unreliable sources may have security risks, so please be careful.
3. Clear the cache and data: find "Application Management" or "Application Information" in the settings, find the potato software and click Enter, then select "Clear the cache" and "Clear the data". Try the installation again after cleaning.
4. Update the system or application: Make sure that your Huawei mobile phone system and application are the latest version. You can try to update the system or application, and then reinstall Tudou software.
If the above methods still can't solve the problem, I suggest you contact Huawei's customer service or the technical support team of Tudou Software for more detailed and specific guidance.
