What is OTG?
OTG is the full form of the word "On The Go". Many types of work can be done easily by connecting two OTG supported devices to each other.
For example: We usually use PC as "USB HOST" and connect various "Flash Drive" smartphones etc. with it. The number of OTG supported devices is increasing over time. That's why a lot of work can now be done without a PC. For example, with OTG support, you can easily send camera photos to a printer without a PC. Also other "USB Stick" with keyboard can now be easily attached to the smartphone. Since the requirements for this OTG feature are many, you can be sure that the device has OTG support by looking at the device specs when purchasing the device.
Everything you can do using OTG
USB OTG can be used to control the device by connecting various "Peripheral" devices such as mouse, keyboard, etc. to the smartphone or tablet. However, note that multiple button or function-rich mice may not work. In addition, various "Storage devices" such as hard drives, pen drives, etc. must be connected to the device through OTG. Not only this, with the help of file manager you can transfer data from these storage devices. You can also play songs or movies from these "External Storage Devices".
How to use OTG?
There are several uses for OTG based on the hardware. For example: for smartphones and tablets, if you have OTG support, you can add keyboard, mouse, hard drive and flash drive to the device. But the thing is not all smartphones or tablets but OTG supported. In that case it is enough to check the specifications of the device to know if your device is OTG supported. Not just OTG support. To use this facility you will need a good OTG cable. This OTG cable is currently available in various smartphone accessories stores. Now another thing to keep in mind is that if you want to connect any type of storage device such as: "Hard drive or Flash drive" with the smartphone or tablet then you need to use the App.
