Here’s what I would have liked.
Apple announces the iPhone 7s and the iPhone 7s Plus. Almost everything looks the same as the iPhone 7 and the iPhone 7 Plus, but almost everything has been improved.
Let’s start with the inside. A11 Bionic chip with Neural Engine, M11 motion coprocessor, better f/1.8 12MP camera, etc. — basically all the new innards of the iPhone 8. But with the new TrueDepth camera from the iPhone X; there’s enough room in the fat forehead for all those sensors.
The entire front glass will be black, to hide the TrueDepth camera. Face ID in conjunction with Touch ID would have made the iPhone 7s the most secure, even more secure than the iPhone X. Put your finger on the Touch ID sensor while looking at your iPhone 7s to unlock. This has to happen simultaneously. Touch ID is something millions of us are used to, so building on what we are familiar with by adding Face ID would have been a much smoother UX transition as well as a more secure one.
The display itself would be the same — 4.7-inch Retina HD display for the non-Plus version and the 5.5-inch display for the Plus version — except that it would not be LCD but OLED: Super Retina HD. The displays would be True Tone and HDR would be fully supported.
The back would have been glass, like the iPhone 8 and X, to enable magnetic charging.
This iPhone 7s would have been great.
