iphone x
Apple's 11th-generation flagship iPhone, unveiled and first put on sale in 2017. Identified by a glass and stainless-steel form factor as well as a bezel-less, rounded front display with only a sensor-housing "notch" along the top edge, and no "home button". The back features two cameras in a black, vertical, pill-shaped enclosure, with a flashlight in between.
Visually identical to the 12th-generation iPhone XS and iPhone XS Max.
If it has a flat-edged chassis instead of a round one, it's iPhone 12 or iPhone 12 Pro.
