Please follow the below steps:
1. Check whether the Restricted function is enabled in the phone. If so, try disabling the function to run the software. Find the app icon on your screen, long press and go to App Info>Battery>Manage Battery Usage>Optimised.
2. Check whether your phone network is normal. If the network is not optimal, try restarting your phone and replacing it with a better network before running the software.
3. Confirm whether the phone's system is the latest version. If not, try upgrading to the latest version, then open the software and try again.
If the issue persists, contact the Nothing Support Team for further assistance.
