One-click move to SD card
Open the system settings, find "Applications"-"All", then select those programs that occupy a lot of memory and move to the SD card with one click. If you think the operation is too complicated, you can also try PC-side software like pea pods to help.
Back up personal data
Reluctant to delete personal data? No problem! Back up SMS, MMS and email to the network or PC, and then delete them safely.
Uninstall software that is not commonly used.
You hardly need some software, so uninstall it! Go to mobile phone system settings-"Applications"-"All", find the software that is not commonly used, and click "Uninstall" to be OK. However, it should be noted that some applications do not support uninstallation.
