Why does "Insufficient system disk space" appear when booting? Is there a solution?

Based on your prompts, I judge that your mobile phone is a NOKIA series mobile phone. The internal memory of NOKIA S40 or S60 mobile phones is generally not too large. It is recommended to give priority to "memory card" when installing software or taking photos. There are several ways to deal with the warning "Insufficient system disk space":

1. Remove the memory card and keep the SIM card to start the phone (if there is no more warning, take this opportunity to go in and clear some things, including Files remaining in the "Inbox" when wirelessly receiving data);

2. Connect the USB to the computer, install the "PC Suite" that comes with the purchase, mobile phone settings -> connection -> xxx suite, through the PC Go inside the phone to delete.

3. Factory settings -> Reset (the data in the machine may be deleted and restored to the original state.)

4. Flash the machine. .

Note: The above steps should be taken only when the above steps cannot be solved to avoid unnecessary losses. Please bear the consequences.

Also, next time you ask a similar question, please tell me what model it is, and don’t let netizens rack their brains to guess for you. .
