I don't recall photo's of Jenner with phone in hand but I do recall the photo's that appear to show Jenner smoking a joint in the seconds leading up to the crash. I wonder if he was tested for cannabis?
Replying to my own post it appears that I was WRONG! I just discovered this picture of Jenner clutching in her (at the time "his") right hand what appears to be a smartphone! If you zoom into the picture you can see a white object that looks like a smart phone (either Apple or Samsung).
