Gruveo mobile apps include a feature called Selfie Mode which lets you see full-screen the video that comes from your camera. Selfie Mode is handy if you are showing a particular detail to the other call participants (e.g. a product you’re selling) and want to ensure that it looks its best on the other end of the conversation.
Using the Selfie Mode is simple: Tap own video in the upper right corner and see the picture coming from your camera spanning full-screen, just like the other call participants would see it. To go back, tap the picture in the upper right again.
You can toggle Selfie Mode during a call, and also while waiting for a call to connect.
