Samsung M400. Checked that the firmware is current.
Try the power off on. If it doesnt work just save yourself the 40% higher accident rate and dont connect it to your car and all is well.
Personally I dont mess with phones in my car. If they need me, I assume they need me alive. Because of the phone thing I have become a hyper safe driver. I assume everyone else on the road is going to do something moronic. (I mean the IQ thing). So far none of them has hit me other than the 60 year old lady in the Kroger parking lot that backed into me while on her phone. Not a lick of damage to my vehicle but her husband was sure to bitch about the 2k damage to her enviro car. ;-)
