Why did glory 10 update the system, but there was no sound reminder of incoming calls and messages and no vibration, but there was media play?

1, the phone is silent and can't be heard. —— Solution: Set vibration or ring.

2, harassing the phone, hanging up without a sound. -Solution: Ignore.

3. The signal is disturbed or the signal is not good. Solution: move to a place with good signal.
