Why does the OPPO phone display that the memory is full?

If you find that the storage space of the mobile phone is insufficient during use, you can try the following operations: 1. Regularly clean up unimportant files in the mobile phone; 2. When there are many photos and videos, you can save them to an external memory card or upload them to the cloud for storage; 3. Back up data (contacts, text messages, etc. ) and restore the factory settings. If the remaining space of the mobile phone is enough to indicate that the storage space is insufficient, you can back up the data of the mobile phone and take the mobile phone to the local OPPO customer service center for processing.
