Recommendations

1. Do not open several programs at the same time when using a smartphone. Generally, it is appropriate to open less than 3 programs. Large programs can only be run one at a time.

If you encounter this situation, you can only try to format the memory card. If the problem persists, you may need to consider replacing the memory card. Therefore, when installing software, it is best to carefully select the memory card as the installation location.
