Hi. I've had a S6 which was set for the screen to remain on when powered up in a vehicle. My S9 screen is also set up to do this, but the screen and charging do not automatically resume whenever power is disconnected, like when the ignition is turned off, and turned on again, like whenever the power is resupplied. I have to unplug the charging lead and reconnect it to resume charging and keep the screen on. My S6 worked perfectly in this respect. Any ideas please?
