After you have updated your Samsung Galaxy S5 to the new Android Lollipop 5.0 firmware, you can experience the following if you wish to activate the "Car mode" via the status bar:
Within the status bar the icon with the steering wheel for the car mode appears as usual, but it is blind coded and not lighted. However, it cannot be activated as usual.
If you have also this issue on your Samsung Galaxy S5, then this has nothing to do with a malfunction, but with a setting. We now want to show you which setting it is and how to use the Car mode on the Samsung Galaxy S5 with Android lollipop 5.0 as usual.
The setting, which causes this problem is the so-called priority mode, also called Interrupt mode, which can be activated via the status bar. This mode can be used, for example, to switch the Samsung Galaxy S5 completely silent.
But unfortunately the car mode works only if the interrupt mode is set to "All". If the interrupt mode is set to "priority" or "None", then the car mode cannot be used and is blind highlighted. In both the car mode button is blind coded and cannot be activated. Only at "all" the car mode can be activated.
You know now how to activate on the Samsung Galaxy S5 car mode.
