Sometimes when I plug into my USB car charger, it seems to detect it as a computer, and asks what USB mode I want to use. I can only choose "mass storage", because anything else causes the phone to go into MTP mode & won't go away until I unplug the USB cable. Other times, it just starts charging & doesn't ask for a USB mode. The big issue is that when it does ask for a USB mode, and I set it to Mass Storage, apps like Listen suddenly can't "see" or use the internal SD card & bitches, "No SD card" and stops playing. Can't listen to podcasts in my car? Deal breaker! Why is this so random? Thanks.
