The speed shown when driving was left centered. It is activated above 30 km / h.
This application was designed for tablets and cell phones of those who drive. It works in the following way, when detecting a speed higher than 10 kms / h the screen is left in black and the buttons blocked, in this way, if you are driving, you can not use the cell phone or tablet. If you have an incoming call you can only answer if you have installed a hands-free system that allows it.
When parking, it will be unlocked again.
