There are some steps that can easily fix the hanging problem in your device:
1. Update/Download All Applications from Play Store.
2. Check the phone memory, if it is too full to cause hanging, delete some files/images that are not in use and uninstall the app that is too large or useless.
3. Use the phone in a strong internet signal environment.
4. Don't download many files /open many Apps at the same time.
5. Clear background Apps, clear caches (Settings>>App Management>>Select Apps>>Storage Usage>>Clear Cache) regularly, and limit the APP self-starting in the phone manager.
6. Perform regular scanning of the device from the security center.
7. Move Large Files/Photos/Video to SD card.
8. Can set back to factory mode in setting, but this way will delete your own data /images/Apps, please backup them first.
We hope this will help you. Further, if the issue persists kindly let us know by writing an email at service@realme.com
