1. The most common is that unknown software installation failed.

In fact, you have this right when you use Saipan mobile phone. This only needs to be set in the mobile phone security settings. This is also an option added by operators to ensure that users will not install unofficial applications indiscriminately, resulting in disorder of mobile phone systems.

Solution: Just set the installation permission, and then open it in Settings-Security-Unknown Source. 2. I believe everyone understands the reason why the installation software prompts insufficient memory. If the memory of the mobile phone is really not strong and you want to install more programs, then change the mobile phone. Solution: It is also very simple, just release the memory space of the mobile phone (by deleting some useless third-party programs).

What kind of horse to ride, what kind of saddle to put on, and broken cans and falls are inevitable problems, so don't entangle. Unless you replace what you have now, that is the only solution, otherwise you don't have to worry about so many system reasons. Now many softwares don't support systems below 4.0. This can still be solved by upgrading the computer: solving the parsing error of the installation file by upgrading the computer.

This truth is obvious, even this is not allowed to be an apk file at all, but the suffix extension has been maliciously changed by others. Solution: There is no way.

2. Why can't I install software on my Huawei phone?

Open the phone settings and click "Security and Privacy".

Click More Security Settings.

03

Just turn on the switch behind "Location Source Application Installation".

04

After opening, there will be a corresponding safety reminder when installing unofficial software, and it can be installed after checking and confirming.

There are many reasons why the software can't be installed, probably because the program is not in APK format, and Android phones only support software in APK format.

If the program is not downloaded from the application market, the source of the trusted program needs to be set before installation. In Settings >: Advanced Settings > Security, turn on the Unknown Source switch, and then install. So it is best to download the software from the application market.

It is also possible that there is not enough storage space to install. You can use "Mobile Manager" to clear the cache and system garbage, and uninstall unused applications.

If it is installed on an SD card, it cannot be used if the card is not installed or broken. Try to re-insert the card to restart the phone or replace the SD card.

It is also possible that the network is bad and the downloaded installation package is damaged or incomplete, so you can delete the installation package and download it again.

If this software is installed in the mobile phone, download and install it after uninstalling. If the software is not compatible with the mobile phone, it cannot be installed.

3. Why can't Huawei install programs on mobile phones?

The reason why Huawei mobile phone can't install the program and the solution are as follows: 1. Unknown software installation failed. Just set it in the mobile phone security settings.

This is also an option added by operators to ensure that users will not install unofficial applications indiscriminately, resulting in disorder of mobile phone systems. Solution: Just open the installation permission from unknown sources in Mobile Phone-Security Settings.

Second, the system version reason Now many softwares do not support systems below 4.0, which can still be solved by upgrading. Solution: Upgrade the mobile phone to the latest system and try to solve it.

Third, the mobile phone installation software analysis package error Android apk program analysis package has problems, because the downloaded apk program itself has problems, and the compressed package of the program may be damaged during the download process. Recommend downloading again. .

4. Why can't Huawei phones install software?

If it still doesn't work after clearing the cache and restarting, restore the factory settings.

The specific operation method is as follows:

PS: Please back up your mobile phone data before returning to the factory to avoid losing important mobile phone data during operation.

5. What is the reason why Huawei's mobile phone can't download software?

1. Note that the installer is in APK format.

If the mobile phone software is not in APK format, downloading is futile. Please check that the format of the third-party application is correct. Android phones only support third-party applications in APK format.

2. Set the trust source of this program.

If the application is not downloaded from the application market, it is recommended to download the official version and install it in the application market. For security protection, if you install the installation package downloaded from unofficial channels, you need to trust the source of the program to install it normally. Go to settings > advanced settings > security, turn on the unknown source switch, and then reinstall the application.

3. Clean up files to increase the remaining storage space

Insufficient remaining storage space may also lead to software installation failure. Please use the mobile phone housekeeper to clear the mobile phone cache and system garbage or uninstall unused applications.

4. Check whether the microSD card cannot be recognized or damaged by the mobile phone.

If the application is installed on the microSD card, please check whether the microSD card cannot be recognized or damaged by the mobile phone. Please reinstall the microSD card and restart the phone or replace the microSD card.

6. What if Huawei can't download the software?

1. Settings-Manage Applications-All-Download Manager-Enable, and then restart the phone download.

2. See if the networking control of the security center that comes with the mobile phone is limited. 3. Open the security center that comes with the mobile phone and find the function of traffic monitoring. If you turn on a networking control function, you can see whether it is restricted from downloading software directly.

I suggest you follow the following methods: 1. Please check that the format of the third-party application is correct. Android phones only support third-party applications in APK format. 2. If the application is not downloaded from the "application market", it needs to trust the source of the application before it can be installed normally.

Enter the "Settings" interface and click "Settings All >"; Security, turn on the Unknown Source switch, and then reinstall the application. 3. It may be caused by insufficient remaining storage space.

Enter the "Mobile Manager" interface and click "Cleaning Acceleration" to clear the mobile phone cache and system garbage; Click "phone manager > application management > application uninstall" to uninstall unused applications. 4. If the application is installed on the microSD card, please check whether the microSD card cannot be recognized or damaged by the mobile phone. Please reinstall the microSD card and restart the phone, or replace the microSD card.

5. The downloaded third-party application may not be compatible with the mobile phone, so it cannot be successfully installed. Please try downloading other similar applications.

7. What's the matter that Huawei's mobile phone can't install applications?

Please check the treatment according to the following methods:

1, out of memory

Please clean up the internal storage space to ensure that there is enough installation space. If there is a hint of insufficient memory during the installation, it is recommended that you clean up the background application and try the installation again. You can also do the following.

EMUI 5。 X: Settings > Application Management > Huawei Application Market > Storage.

EMUI 8。 X: Settings > Applications and Notifications > Application Management > Huawei Application Market > Storage.

EMUI 9。 X: Settings > Applications > Application Management > Huawei Application Market > Storage.

Huawei application market deletes data and empties cache. Then, download and install the application from Huawei application market.

2. Incompatible applications

I suggest you download the required applications from the application market. For incompatible applications, the application market will prompt incompatibility. If the application market prompts that it is not compatible, I suggest you consult the application developer to see if there are any applications compatible with your mobile phone version available for download.

3. For installation pop-up prompts, such as failed installation analysis and no signature:

Please download and install again when the network conditions are good. The connection between the currently used network and the upgrade server is unstable, packet loss or damage occurs when downloading the update package, and the verification of the update package fails.

4. Please confirm whether the installation package source of this application is safe.

It may be because the application installation package has security risks (such as trying to modify system files). If you try to modify system files during application installation, the installation will not succeed. It is recommended that you download and install the application from Huawei application market, or obtain a reliable application installation package from official channels.

Please check whether the third-party eye protection software is installed on the mobile phone. If so, please close such eye protection applications before installation. If the third-party eye protection software is not installed, it is recommended to restart the phone and then install it.

6. Please check whether the third-party housekeeper software (such as 360/ Tencent Butler) is installed, and then try to install it after uninstalling.

7. If the above methods fail to solve your problem, please back up the information in advance and bring the purchase invoice to Huawei customer service center for testing and processing.
