[Concept] GoPro Explorer Phone

Imagine a phone nobody asked for...
A rugged phone that doesn't require any casing. So thick, it might not fit in your pocket.
No front-facing camera required. All you need is a secondary screen for your selfies.
Hypersmooth 2.0
It comes with a small built-in battery and a removable battery, so it doesn't require to switch off the phone to swap the battery.

All completely done in Adobe XD.
