Most Blackview Rugged outdoor smartphones come with an extra button on the left. The button can be used to do many things like opening flashlight or SOS. For users of Walkie Talkie App like VoicePing, you can even use it as PTT button.
Doing this will allow you fast communication as you don’t have to touch the screen to talk. In most Blackview Phones with the proper setup shown below, you can even talk when the screen is OFF. You don't need to open the app each time you want to PTT and since the screen is kept OFF, you won't accidentally touch other apps.
