- DConnect the device to a PC and run Windows System File Checker (sfc /scannow) via USB debugging.
Answer
Disable Background App Refresh for the application and perform a force restart of the mobile device.
Disabling Background App Refresh for the flight-manifest application prevents it from executing unwanted sync processes and consuming CPU/battery in the background. Pairing this with a force restart flushes corrupted temporary cache and RAM states causing freezes, adhering strictly to least-invasive troubleshooting protocols.
