How to enable USB mass storage on Samsung Galaxy S4? Well, it is not possible for the moment. SGS3 Easy UMS application (which works on Galaxy S3 and Galaxy Note 2) is not working on Galaxy S4 Android 4.2.2 Jelly Bean. By the way, SGS3 Easy UMS is able to make external micro SD card as USB mass storage only. It can’t mount internal storage. Therefore, you are stuck with card reader now. Personally, I think this is better. Why? Galaxy S4 still does not support UHS-I standard. Therefore, you are not getting the best reading and writing speed out of your microSD card. My 64GB Samsung microSDXC Pro UHS-1 Card is able to get 75 MB/s reading on card reader while 36 MB/s on Galaxy S4 only.
How to enable USB mass storage mode on Google Nexus 4? A big NO. Just like other Google Nexus devices, Nexus 4 does not support USB mass storage mode as well. You have Media device (MTP) and Camera (PTP) protocols only for USB connection. Or you can use Wi-Fi connection to transfer files between Nexus 4 and PC. Use free Android application like AirDroid.

How to enable USB mass storage mode on Google Nexus 7? Well, don’t think about it (at least for now). Nexus 7 does not support USB mass storage mode just like Samsung Galaxy Nexus. Only Media device (MTP) and Camera (PTP) protocols are supported on Nexus 7. Google does not want you to use USB cable much on Nexus 7. Use wireless connection to transfer files between Nexus 7 and PC instead. Easier…

I love exFAT supported external micro SD card on Samsung Galaxy S III. I can enjoy movie video that more than 4GB file size finally. However, Samsung Galaxy S3 does not support USB mass storage mode natively. Android 4.0 Ice Cream Sandwich seems to disable USB mass storage feature. Latest Samsung Galaxy S2 ICS firmware does not have this feature too. But worry no more, there is an application called SGS3 Easy UMS can help to enable USB mass storage on Samsung Galaxy S3. It will make external micro SD card on Samsung Galaxy S3 available as USB mass storage device. It supports exFAT for the moment (tried FAT32 but not working). Come on, try it out. Don’t stick on Media device (MTP) and Camera (PTP) mode only. Note – root access is required.
