1. If the phone is stuck, try unplugging the headset and reinserting the phone.
2. Shut down and restart the device, and then insert the headset.
3. Check whether there is any problem with the headset, such as the headset cable is broken, the headset is not plugged tightly, etc., which will cause the phone to not respond.
4. The headphone jack may be blocked or the plug socket is in poor contact. You can try to clean the headphone jack or go to Huawei for after-sales testing.
