Samsung Galaxy S3 - Developer Edition (VZW) Not Installing USB MTP
For some reason my Samsung Galaxy S3 isn't recognized via Windows 7 (64-bit). I plug the phone in via USB and it's not recognized. I looked around for solutions to this but it seems there are many ways to solve it but no definitive best practice. Also most solutions appear to be from 2012 or older. This problem just started for me and with my work PC. My home PC recognized it in the past although I haven't tried it in the last few weeks. I already tried uninstalling the drivers for the Samsung Galaxy S3 on my PC then plugged it back in via USB to let it re-install. Most of the drivers get installed ok except for MTP Device.
I also went to the official Samsung site to download drivers but that didn't help either. Attached are screenshots of what I've done. It's weird that Windows says the driver is up to date but still shows the exclamation mark like there's something wrong and the device doesn't show up under "My Computer" like other mounted USB devices. Thanks for any help.
