Whether this mobile phone version is higher than the software version is mainly due to the following reasons:

1 Your mobile phone is out of memory. It is recommended to delete some uncommon software.

2 Move all removable software to SD card.

Process management of background software is often carried out. So as not to occupy a certain amount of memory in the background!

If none of the above works, it is estimated that it is a problem of software adaptability. Suggest changing the software to try!

I hope it works for you!
