Meizu 3 mobile phone can't hear the sound for several seconds (nearly 10 seconds) before answering the phone. If you ring for a short time when you make a phone call, so will the first few seconds.

1. If the external SD card is installed on the mobile phone, it is recommended to pull it out and test it (excluding the reasons for the poor performance of the external SD card).

2. Is there any improvement in the attempt after restarting the machine?

3. In standby mode, press and hold the physical key in the middle of the phone for more than 2 seconds-select the lower left button in the pop-up interface-if there is an application running, select the right side to complete it all.

4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

Try it first. Many situations are caused by these reasons, and there are many mobile phones just like yours. Don't worry.
