Question [Q] USB Mass Storage not working?

Hi, when I had my SGS3 I was able to plug it into my TV via USB and explore the phones files (helpful to play movies ect without having to transfer it to laptop via USB then to a portable USB pen drive).

However when I plug my Nexus in, it doesn't see it at all so can't go through the files with the file browser.

I noticed when I open 'my computer' this appears - (see screenshot)

My old SGS3 just came up directly with internal storage rather than showing the phone model first, is this related to the issue?

Cheers!

the Nexus 5 does not mount USB storage by default.

You must either:

1) Buy Nexus 5 media importer (non-root)
2) Use USB OTG Helper or Stickmount from play (Free but requires root)
3) Use a custom kernel (such as Chaos) to enable Automount of OTG

This was one of the annoying things I've found with the Nexus 5. Not sure if the rest of the Nexus line is the same but I can't see why the Nexus 5 doesn't have full USB OTG support like a lot of other phones out there. My S3 and Toshiba Excite 10 but support full OTG but why not the flagship Google device?

That said, my Toshiba supports micro HDMI whereas both the S3 and Nexus use MHL and Slimport respectively. I know this is probably due to space constraints to fit two ports on a phone but its still annoying that you need yet another cable to hook up your phone to a TV without any lag like miracast.

Indeed it's annoying..

I actually tried the first two options of rootSU's answer however it didn't mount (which is strange as I am on stock ROM)

I will try the kernel tomorrow

1) what is the usb stick formatted to? Anything other than fat32 will fail
2) whats the error? With stickmount, it just mounts it to a folder on /sdcard. Nothing happens visually

Kernel is best option though

I think you are missing what the op is wanting to do.
What you are describing is allowing the phone to access an external device.
The op wants his external device (TV) to access his phones storage.
Unfortunately this is not possible unless your TV supports the mtp protocol which it looks like it doesn't.
Starting in android 4.0 Google moved away from a physical fat32 sdcard partition and went with a scalable fused ext4 sdcard Mount.
This required a new interface because the new style cannot be mounted as a USB mass storage device.
Thus came mtp. (Media transfer protocol)
Using the fused system is much more beneficial in android (I won't go into the reasons now) but it means you cannot use the device with anything that doesn't support mtp access

Oh yes I am missing that.

FYI, sgs3 is an mtp only device
