A：1. Please try restarting your device.
2. If the device has been powered on for an extended period and too many programs are running in the background, it may exhaust system resources or cause other abnormalities, potentially leading to a system crash. We recommend that you close infrequently used applications regularly, periodically clear system cache and junk files using system settings, and manually restart the device. Observe whether the crashing issue persists after a period of time.
3. Overheating can also cause the device to crash. We recommend avoiding using it while charging or placing it in a high-temperature environment.
4. If the above factors are ruled out, please download the device firmware and flashing tool, and upgrade the firmware via a wired connection to a computer. If the problem persists, please contact after-sales service for repair.
