What if Xiaomi's mobile phone is full of memory?

First, I suggest you buy a larger SD card, and then transfer the data in the phone memory to the SD card, such as pictures.

Second, I suggest you install a management software to clean up the memory. Mobile phone applications will generate a lot of cache. Some caches can't disappear automatically, or they are data garbage. It takes some time to clean up.

Third, QQ and WeChat cache the most data. Tencent has a mobile phone housekeeper, which can clean up more data on WeChat. Of course, you don't like this software. You can clean up and delete the mobile phone housekeeper.
