Ok, so im a new android user having switched to a Galaxy S7 from an iPhone. Got a micro SD card for the S7 and added some music to it. Plugged it into my car and was able to listen to music through the USB slot via an "MTP" connection (whatever that means, sorry im clueless). All fine untill a few days ago. One night I install a minor update to the phones software and the next morning on my way to work my phone wont come up on the cars display when i plug it in. I connect the USB cable, and a prompt comes up on my phone asking me to allow MTP connection. Thats normal, so far, i click allow. But then where my Phone is supposed to come up on the Connected device is just says "USB Device" as it does when nothing is connected. I cant click on it as the "USB device" is greyed out. whats going on? Has the new update bricked my Cars connectivity with my new phone?
