A guide on using USB OTG on Moto G and Moto X to expand the storage

What’s Moto G USB OTG?

USB On-The-Go (USB OTG) is not a new technology. It allows a device to perform both master and slave roles in USB connections. Android fully supports USB OTG since Android Honeycomb 3.1.

Normally USB uses a master/slave architecture.  A host acts as master device for the connection, the other USB device acts as slave.

Devices are designed to assume one role only. For example, when you connect an externl disk to the PC, PC is always the host, and external disk is always the slave.  When you connect two external drives through USB, nothing happens.

For Moto G, like many other phones, when it is connected to PC, it will be acted as slave and mounted as a storage device.  You can access the file on the Moto G from your PC.

But what happens if you connect a USB thumb drive to Moto G?

Moto G can mount it as external storage and you can use it just like you use external drive on a PC!

Because Moto G supports USB OTG.

Of course, there are some other requirements to make it work.

We will discuss them later.

How Moto G USB OTG can help Moto G owners ?

So, basically, Moto G USB OTG makes it possible for you to use external USB devices on Moto G.

Storage is just an example. The miserable storage in Moto G usually is the motivation for some owners to find ways to expand the storage.

You can also hook many other USB accessories, e.g., even an USB keyboard or mouse.

In this guide, we will focus on storage because it is the most wanted Moto G USB OTG usage.

Also this guide applies to Moto X and many other Android devices, although Moto G is used.

What do you need to use Moto G USB OTG to expand your storage?

To use Moto G USB OTG to expand your storage, you need one of them:

  • an USB OTG adapter (less than $10). One end of the USB OTG adapter connects to USB storage, which can be a normal thumb drive or even a portable hard disk. The other end connects to Moto G directly.
  • or, an USB OTG flash drive (price depending on the capacity. It is slightly more expensive than normal USB thumb drives with similar capacity.). Such drives usually have two USB interfaces. One large female interface allows it  to be used as normal USB thumb drive on PCs and laptops.  The male micro USB interface (OTG micro plug) allows you to insert the drive to Moto G directly.

So, if you want to use your existing thumb drives or portable disk, you can invest a few dollars to get a OTG adapter. The adapter can also be used for other USB devices.

If you are considering to get a new thumb drive, it is time to consider an USB OTG flash drive. It will be slightly expensive than normal thumb drive with similar capacity. But you can use it on both phones and PCs without any adapters.

How to use Moto G USB OTG storage?

Once you connect the USB OTG flash drive, or  a normal flash drive through USB OTG adapter, to Moto G, you can find it in Settings— Storage as shown below.

As shown in the screenshot, the USB OTG storage should be shown under USB disk.

In this case, a 64GB  storage was successfully mounted  and is ready for use on Moto G.

moto_g_usb_otg_moto_x_2_usb_storage

Once the USB OTG storage is mounted, you can use it just like a SD card. You can copy files from or to it.

Also, all media files in the USB OTG storage will be scanned automatically. So, you can access them directly from most apps.

If you want to play with individual files on the storage, you need a file manager.

In this guide, for example, you want to locate a file and play it.

You can use any file manager apps, e.g. ES File explorer.

In ES File explorer app, you need navigate to the root of the partition by tapping the “/” as shown below.

Now tap storage as shown below.

moto_g_usb_otg_moto_x_3_root_directory moto_g_usb_otg_moto_x_4_storage_folder

In /storage, you can find usbdisk folder. This is the USB OTG storage you mounted.

Tap usbdisk as shown below to browse it.

Now, you can find all files and folders in this thumb drive.

You can copy them to internal storage. You can also copy files from internal storage to this folder.

You can also play the music file on this drive directly without copying it to the phone as shown below.

moto_g_usb_otg_moto_x_7_play_from_usbdisk moto_g_usb_otg_moto_x_8_unmount

Important!! You must unmount the USB OTG storage before you remove it from Moot G!

After using USB storage, you should unmount it before unplug it from Moto G.

To unmount Moto G USB OTG storage, you need go to Settings—Storage.

As shown earlier, you need tap Unmount USB On-The-Go storage.

Then, you should get the confirmation page as shown above.:

Unmount USB On-The-Go storage?

If you unmount the USB On-The-Go storage, some apps you are using will stop and may be unavailable until you remount the USB storage.

Tap OK as shown above to unmount the storage.

If you unplug the storage without unmounting it, you may damage the thumb drive and lose all data on it.

Can I use USB OTG on Moto E?

No, Moto E does not support USB OTG.

However, Moto E 2nd Gen (Moto E 2015) supports USB OTG.

Can I use USB OTG on Moto X, including Moto X 2nd gen?

Yes, Moto X, Moto X 2nd Gen support USB OTG. You can use USB OTG devices exactly as in Moto G.

Does other phone supports USB OTG?

All current Nexus devices, Nexus 4, Nexus 5, Nexus 6, Nexus 9 support USB OTG.

Most Samsung Galaxy phones (Galaxy S3, Galaxy S4, Galaxy S5, Galaxy S6, Galaxy Note 2, Galaxy Note 3, Galaxy Note 4…)  also support USB OTG.

Some LG and HTC phones also support USB OTG.

Recommendations of USB OTG adapter for Moto G and Moto X

USB OTG adapter usually is not expensive. It should cost you less than $10. You can get it from Amazon or local shops.

But you should try to get a quality one. The poor quality connector may damage your USB port.

1. StarTech 5in Micro USB to USB OTG Host Adapter:$4.99

2. aLLreli Micro USB Host OTG Adapter Cable for Moto G: $4.99

3. If you need connect more than 1 USB device to Moto G simultaneously, try  Inateck Multi-in-1 OTG Adapter Cable: $25.99

Recommendations of USB OTG flash drive for Moto G and Moto X

Although Moto G and Moto X only supports USB 2.0, you should get an USB OTG flash drive that supports USB 3.0. This can save you time when you use the drive on PCs or laptops.  Most new PCs and laptops support USB 3.0.

The quality of USB OTG flash drive is very important. Don’t save money on unknown brands.

Nobody wants to lose data!

Also, when choosing USB OTG flash drives, do NOT choose the 90 degree design.  The two USB interfaces should align with the main body so that you can connect it to Moto G easily even if you are using cases.

1. SanDisk Ultra 64GB USB 3.0 OTG Flash Drive:around $25.  If you are on budget, you can get 16GB (around $6) or 32GB (around $15).

2.  Corsair Flash Voyager GO 64GB USB3.0 micro USB OTG Flash Drive for Android devices Similar price as SanDisk. Lower capacity (32GB and 16GB) options are also available.

    I have a moto X 2nd gen (on android 6.0), a vention OTG adapter, a kingston mobile lite G4 usb3 SD card reader and a kingston SDHC card.

    I use ES explorer for a while now, the sd card and sd card reader works fine on PC, the otg adapter worked for an external HDD (although the power output wasn’t enough)

    Simple question :

    Why doesn’t it work ?

    Many thanks !

  16. Recently purchased Moto G4 Plus (on Marshmallow 6). Can mount a usb flash drive and access its files via settings/storage/usb.
    On ES file explorer, first time use, it seeks permission to enable access to usb drive and after that there are no problems.
    My issue though is, prior to M6, I could access all my photos (classified in different folders) on the usb via a gallery app or QickPic app as thumbnails. But now under marshmallow these apps cannot access usb otg. Even the native Photos app cannot access usb drive.
    Is there anyway that I can enable some permission, as in ES file explorer, to access my usb in these gallery apps.

  20. Dear, updated android version 6.1 marshmallow in moto g3. Otg doesn’t show in es file explorer…
    Why???

  22. With the OTG I can avoid the velocity issue that the micro sd have? Because if I expand the storange with a micro sd I need certain requeriments like the read and writing velocity. Also that the biggest micro sd that I can use in the Moto G3 is the 32gb and it need to be sdxc. So if I buy an OTG cable and any USB of 128gb I don’t have to worry about those things?

  28. I’ve been using FX Explorer for my otg on moto g2 before the 6.0 update after which it stopped detecting.
    Since then I’m not able to find an app to toggle the write access on my pen drive which is required during some errors.
    Any suggestions on better apps since ES Explorer is what I use and it doesn’t have that option or am I missing something?
    Thanks 🙂

  31. I have a Moto X first generation bought in 2014. It has 3G. And I wish to use it for generating the Digital Life Certificate for pension. I have downloaded the application JeevanPramaan for this. Now I have to connect a fingerprint scanner (MFS100 from Mantra). have got it and when connected using USB OTG adapter, it is recognised by the app. But during the process, the scan is to be done, and for this the light in the scanner should be on. However, this does not happen. So scanning of fingerprint is not done. Could you explain why and what should be done to solve the issue. I think that the scanner is not getting the power needed through the USB OTG. If so, what is the solution?

  47. You show the screenshots of the Lollipop OS, but this upgrade does not allow use of OTG storage on Moto G. Out of the box for first generation allowed use of the OTG storage. After system upgrades, this is greyed out. Did you only upgrade the screenshots here and not your information, or have I missed something? Please tell me, as I would really like this feature restored.

  71. Hi Simon,

    Thanks for a separate guide for OTG which I was expecting for. I have a query regarding the OTG. Please let me know whether you too have faced the same problem.

    If I Unmount the OTG (Sandisk ultra dual 16GB) from mobile, it disables the application stored in SD card. It works only if I power off and power on the mobile or unmount and mount the SD card.
    Please suggest..

    SD card apps works fine untill the OTG is connected in mobile. The problem is only after unmounting the OTG. I think while unmounting the OTG, the mobile is unmounting SD card as well. Not sure about it.
