After receiving the M2 car mount, I have noticed a troublesome problem. When the phone is docked, and I hit the top unlock button, and then attempt to swipe down, I get either no response, or occasionally it will unlock the screen. If I use my other hand to hold the phone, it will unlock normally. Obviously, this will not work while driving down the road. I have seen on other forums either this EXACT problem, or a problem with the device laying on it back. Also, if I do get the phone to unlock, navigating while in the dock is very erratic. I'm curious if anyone is having a problem with their phone while in a car dock, or lying on a surface and will not unlock without holding it with your other hand. Any help is appreciated.
