I have been trying to figure out why the new phones are using MTP instead of USB mass storage. What was the problem with something that had become ubiquitous. With USB mass storage so popular, drivers are baked into every OS, TV sets, Cable boxes, Stereos, Cars and more. Just plug it in and go. This MTB crap barely works with anything. You need special drivers that work with specific devices. Basically, it sucks. I upgraded to an S3 last year and my car radio can no longer read my music files; I have to use Bluetooth. My little clock radio no longer reads my music and every computer I use has to have Samsung drivers installed. Does anyone know why Google doesn't like Mass USB?
