When "iphone6" uses other apps, why is there no sound reminder when receiving SMS and WeChat?

You can view new message notifications and open them.

When you see the first person who receives a new message notification, if it is closed later, you need to turn on the message reminder under Settings-Notification.

If it is turned on, you need to check whether the sound reminder is turned on under Settings-Notification.

Open Settings-Notifications

Look for wechat in the notice

Open the permission notification of WeChat. If you want a voice reminder, you need to turn on voice here, otherwise you just need to turn on voice in WeChat settings, and WeChat still has no voice.

Here you can also set whether WeChat is displayed on the lock screen, whether there is an unread message number in the upper right corner of the icon, whether the message is a banner or a popup window, and so on.

Back to the new message notification on WeChat, you can see that it has been opened after receiving the new message notification. Now you can set the message reminder mode on WeChat.

If there is no sound, check whether the mute button of the mobile phone is turned on (the button above the volume button) or whether the do not disturb mode is turned on (there is a moon in the upper right corner of the mobile phone screen after it is turned on, and the closing method: swipe up to open the control center and click the moon icon).

Also, let's turn up the volume of the mobile phone so that we are not afraid of not hearing the sound. thank you
