Why can't mobile phone software be moved to SD card?

The software downloaded by mobile phone is stored in the memory of mobile phone by default after installation, and some software itself does not support moving to SD card.

At present, in order to ensure the running speed and stability of mobile phones, mobile phone manufacturers are not allowed to install applications outside the built-in storage. Only the mobile phone rooted can install the application on the SD card, but the running speed and stability will be affected by the reading and writing speed of the card.

Extended data:

If the mobile phone memory card cannot store data, we suggest that you:

1. Check whether the memory card has enough storage capacity;

2. If there is enough memory, please take out the SD card and insert it again.

3. If it doesn't work, put this SD card into other equipment, observe whether it can be used normally, and rule out whether it is an SD card;

4. If it can be used normally in other mobile phones, please back up the data in the SD card and try to format it;

5. Try to replace another memory card.
