Why does Xiaomi 4 show insufficient memory?

Memory is divided into two parts: mobile phone memory and memory card. In general, the memory of a mobile phone cannot store media files such as songs, videos and e-books. The memory of the memory card is specially used to store these media files. Of course, software can also be installed in the memory of the memory card. Your mobile phone prompts that the memory is insufficient, which has nothing to do with the memory of the memory card. The situation you are talking about should be that you have installed too much software or that the game takes up the memory of your mobile phone. You just need to delete some software games. Or install the software game into the memory card. If you really don't know how to do it, restore the factory settings. But back up your phone book, text messages, etc. Before restoring the factory settings. If you want to know more about this mobile phone, please click to enter the Xiaomi 4 mobile phone topic.
