Pop-Up Selfie Camera (and Face Unlock)
This next slide isn't really a secret. Heck, it's the highlight of the phone and one of the coolest hardware features of any smartphone ever released. That said, it has to make this list.
The OnePlus 7 Pro has an all-screen design because they put the front-facing camera in a mechanical pop-up mechanism on the top of the phone. When you launch the front camera a little light turns on, and the camera slides out from INSIDE the phone, snaps a photo, and goes back inside.
It's one of the coolest things about the OnePlus 7 Pro. Great to show off to your iPhone friends or family, a conversation starter at the bar or a party, and just fun to open and close in general.
Oh, and you can use that pop-up camera to unlock the phone with your face. Just like FaceID on the iPhone, the OnePlus 7 Pro camera will barely open just long enough to see your face, confirm it's you, and quickly close again and unlock the phone all at the same time. It's pretty fast, and you'll love it.
