What if the mobile phone memory card can't hold the software?

1. The mobile phone is not turned on because of unknown source.

This is an option added by operators to ensure that users will not install unofficial applications indiscriminately, which will cause disorder in the mobile phone system.

Solution: Open the location source of the mobile phone.

2. The installation software prompts insufficient memory.

Solution: Delete some useless third-party programs to free up the memory space of the mobile phone.

3. The installation position is incorrect. For example, some programs are installed in the phone memory by default when they leave the factory, which belongs to the built-in system application and can only be installed in the system space. For models supporting external SD cards such as R827T and R833T, some users will choose the "SD card" space as the preferred installation location. If the SD card is pulled out later, the installation will fail.

Solution: The preferred installation location is determined by the system.

4. The system version is too low. At present, many softwares do not support systems below 2.3, and the installation failure caused by this situation is solved by upgrading the Android version (for example, the model of U70 1 has been upgraded from 2.3 to 4.0).

5. An error occurred while parsing the installation file. The apk file is not installed, but the suffix extension has been maliciously changed by others.

Solution: Download through the formal green platform and try it in the software store.

6. Problems with the software itself Due to the openness of the Android platform, there are always some softwares that are incompatible with the system, and such softwares will also fail to install. To confirm whether it is a problem of the software itself, you can compare it with other models.
