Restarting the phone can return to normal. 2. Data recovery software can try to recover deleted files through data recovery software. However, it should be noted that small files such as mobile phone memos cannot be completely recovered due to being stored on a memory card or flash memory on the mobile phone. They need to be used with caution. 3. Go to the phone repair shop and ask a professional technician to check and recover the deleted files. If you have deleted a file but want to try to recover it, it is recommended to back up important data first to prevent similar problems from happening again.
