1. The cameras are vertical, so that means it could be an iPhone 11, iPhone 12, or iPhone 12 Mini.
2. I haven’t memorized the colors of each iPhone yet (rip me), so I looked up each phone’s colors and since both phones had a purple shade, I compared the iPhone 11 purple shade and the iPhone 12 purple shade. The iPhone 11 purple shade exactly matched the one in the picture, so I knew it was an iPhone 11.
