Soft Refresh
This resets your phone without resetting any of your data.
First, hold the power button. Then, tap “ok” to turn off the phone. Next, remove the battery from the phone for about 30 seconds. Finally, pop the battery back in and turn the phone on.
Clearing Application Cache
Clearing the Cache deletes unnecessary temporary data files that take up valuable space on your device. These temporary data files may cause performance issues if they take up too much space.
Go to settings on your phone. Next tap the “Apps” section, then “All.” They, tap the desired app, and tap “clear cache.” Repeat this for all apps, especially the ones that may take up more memory.
Low Storage
Most phones eventually run out of storage which causes many issues.
Uninstall any unused apps, don’t worry, you can reinstall them later if needed.
Next move any applications to the SD card, provided you have one. First go to “settings”, then tap on the “Apps” section. Tap on the desired app, and select “Move to SD card.”
