How to turn on or off speakerphone?
You can enable or disable speakerphone while you are in an active call. To do so kindly following the steps below:
- During an active call, to turn on the speakerphone tap the Speaker icon located at the bottom left corner on your screen. If the icon shows green means the speakerphone is active.
- Tap the Speaker icon to turn it off. If the speaker icon shows grey means the speakerphone is not active.
It's easy, right? You can do the step mentioned above when you receive an incoming call or when you make a call. In an incoming call, the icon will appears once you accept the call. While in an outgoing call, the icon will appears once you hit the call icon. So, hope it helps :)
