Currently, almost all Android smartphones can use the USB OTG feature. However, older phones lack this feature. To unlock the OTG feature, you will have to root and install a custom ROM on your Android device to get OTG compatibility.

USB On-The-Go (OTG) is certainly one of the exciting features of Andriod devices. USB OTG compatible devices (almost every android smartphone) can act as a controller or host for other USB devices. OTG adapters are usually used on smartphones with SD cards and other card readers. But is there a way to use OTG adapters in an unusual way? We will explore 10 things about OTG.

#1 OTG Introduction

USB On-The-Go (USB OTG or OTG) is a specification first used in late 2001 that allows USB devices such as tablets or smartphones to act as hosts and allows other USB devices (such as USB flash drives, digital devices) cameras, mice or keyboards to be connected to them. The use of USB OTG allows those devices to switch back and forth between the roles of host and device. A cell phone can read from removable media as a host device, but present itself as a USB mass storage device when connected to a host computer.
USB OTG introduces the concept of devices that play the role of both master and slave - whenever two USB devices are connected and one of them is a USB OTG device, they establish a communication link. The device controlling the link is called the master or host, while the other device is called the slave or peripheral.
USB OTG defines two roles for the device: the OTG A device and the OTG B device, specifying which side powers the link and which side is initially the host. The OTG A device is the power device, while the OTG B device is the power device. In the default link configuration, device A acts as the USB host, while device B acts as the USB peripheral. Host and peripheral device modes can be exchanged later by using the Host Negotiation Protocol (HNP).
The initial role of each device is defined by which mini-plug the user plugs into its socket.
