This app was marking a lot of brakes even when I did not touch the brake paddle, when I was on my driveway, or when there was no other vehicles along the way. Sometimes it marked a strange and meaningless zig zags a normal human will never did. I changedy mobile phone because of these strange things, but it doesn't help. Same thing happened and CS cannot make valuable supports on this. Please make sure get better compatibilities and GPS functions of this app.
