Not many feature omissions have drawn as much ire in recent memory as the lack of USB Mass Storage. While Media Transfer Protocol has numerous advantages such as safer removal and simultaneous access from both your computer and mobile device, it's just not quite the same as directly mounting your device as standard USB storage. This is on top of the hoops that non-Windows users have to go through to access the storage in the first place.
Thankfully, there's no shortage of tweaks and mods to get the beloved USB Mass Storage functionality back. The newest solution comes from XDA Senior Member MohammadAG, and it is for quite a few Samsung devices including the Galaxy S III, Galaxy S 4, and the Galaxy Note 2. And even if you have a Samsung device that isn't one of the above, it's quite possible that it may still work for you.
As described by the developer:
Features:
- Allows you to use your microSD card as a USB Mass Storage device.
- Shortcuts on your homescreen to easily enable/disable USB Mass Storage mode.
- Warns the user if they try to disable Mass Storage mode without unmounting/ejecting on the PC side.
Tested working on:
