One should be at the bottom one at the top. I understand space on the phone is a premium but a second port would make the phone so much more usable. Wired headphones, flash drives, camera modules, speaker modules, keyboards, even connection to a TV, all could be used while charging. It's a shame it's not a thing, USB is extremely versatile port, but you only get one and it's used for charging half of the time. (I am aware dongles exist)
Sounds neat, but phone sensor is so small and focal length is wide so even if you just mash the shutter immediately, pretty much everything is in focus anyway. I can see why they did away with it.
If you have a Motorola phone then you should just be able to twist your wrist to open the camera instead. Also chop to turn on the flashlight. I miss chop to flashlight the most when I switched away from Motorola.
