I kinda let go this idea. Even if you have the best camera phone, there sill is the mounting question.
It wil be close to impossible to fix the phone that good to remove all shakes and vibrations.
The smaller and lighter the camera is, the less it will be affected by the vehicle's vibes and shakiness. I also tried a phone with OIS, but that only effected in even more liveliness, the lens at some point just bounces up and down.
So in my case the form factor of the mobius, joovuu x, Foxeer etc etc is the best solution for that.
