You can optimize your device and improve its performance using Phone Boost. Phone Boost kills the apps in the background, clears the app cache files, obsolete APKs, junk files, and thumbnail images to free system space on your device.
To increase the device performance:
- Open Quick Heal Mobile Security.
- On the Dashboard, navigate to Device Optimization > Device Cleaner, then tap Clean.
Your device is boosted and further option to clear more files is displayed. You can view details of the junk files, cache files and delete them if required.
