Welcome to Blackview blog. Blackview - One of the well-known rugged phones brands around the world.

OTG, or USB On-The-Go, is a standard that allows mobile devices to act as a host, allowing other USB devices to be connected to them. This means that you can use your phone or tablet to connect to a variety of peripherals, such as keyboards, mice, external storage devices, and even printers.

USB OTG in Android


OTG was first introduced in 2001, and it has been supported by most major mobile platforms, including Android, iOS, and Windows Phone. To use OTG, you will need a special cable that has a USB-A connector on one end and a USB-micro or USB-C connector on the other end. Once you have the cable, you can simply connect your mobile device to the peripheral that you want to use.

There are many different things that you can do with OTG. For example, you can use a keyboard and mouse to make it easier to type and navigate on your phone or tablet. You can also use an external storage device to expand the storage capacity of your device. And if you have a printer that supports USB, you can use OTG to print photos and documents directly from your device.

OTG is a great way to add more functionality to your mobile device. If you have a device that supports OTG, I encourage you to give it a try. You might be surprised at how useful it can be.


Here are some of the benefits of using OTG:

Increased functionality: OTG allows you to connect a variety of peripherals to your mobile device, giving you more flexibility and options.

More storage space: You can use an external storage device to expand the storage capacity of your device, so you don't have to worry about running out of space.

Easier printing: If your device supports OTG, you can use it to print photos and documents directly from your device, without having to connect it to a computer.

More comfortable typing: If you find it difficult to type on your phone or tablet's touchscreen, you can use a keyboard and mouse to make it easier.

If you're looking for a way to add more functionality to your mobile device, OTG is a great option. It's a simple and affordable way to get more out of your device. But the premise is, you need to own an OTG tablet or OTG supported phone(like most of BLACKVIEW ruggedized military grade cell phones).


Here are some of the limitations of OTG:

Not all devices support OTG: Not all mobile devices support OTG. If you're not sure if your device supports OTG, you can check the manufacturer's website or the device's manual.

Some peripherals may not work with OTG: Not all peripherals are compatible with OTG. If you're not sure if a particular peripheral will work with OTG, you can check the manufacturer's website or the peripheral's manual.

OTG can be slow: OTG connections can be slower than traditional USB connections. This is because OTG uses a different protocol than traditional USB connections.


Overall, OTG is a great way to add more functionality to your mobile device. It's a simple and affordable way to get more out of your device. However, there are some limitations to OTG, such as the fact that not all devices support it and some peripherals may not work with it. If you're not sure if OTG is right for you, you can check with the manufacturer of your device or the manufacturer of the peripheral that you want to use.
