OnePlus 6T vs OnePlus 7T: Design
At the front, it's almost impossible to tell these two phones apart. They're both almost all screen, have tiny bezels, and have a small waterdrop notch for the front-facing camera. If you look close though, the OnePlus 7T notch is smaller and easier to forget about.
Around back is another story entirely. OnePlus is using a new premium design that's more curved, delivered a stunning Glacier Blue and Grey color options, but then they put a massive triple camera setup back there too.
You'll instantly know which one is the latest model by looking at the back. The OnePlus 6T only has two vertical cameras, while you'll enjoy a triple camera array in the huge black circle on the 7T. That aside, the design is mostly the same.
