USB OTG - what is it and what can it be useful for?

Modern telephones are equipped with many practical and life-facilitating functions. One of them is USB OTG. What is it and how to check if we have it on the phone?

USB On-The-Go (OTG)

OTG is a function that allows you to connect your smartphone with devices or accessories such as a keyboard, mouse, 3G modem, gamepad or pendrive. To use this type of amenities you need two things: a smartphone that has this function and a suitable cable that you can connect your phone to a peripheral device.

What is the use of USB OTG?

USB OTG is useful in many situations, especially when traveling, when you can not take your laptop or tablet with you. With the USB OTG cable you can, for example, connect a USB memory stick, mouse, keyboard, hard disk, webcam or other smartphone to your phone or tablet. This is useful if you want to write, for example, a report or a longer one on the tablet using the keyboard. There are also OTG cables with distributors that can be used to connect multiple devices to the device.

You can use this solution in many ways. Here are some of the most popular:

  • if you connect the keypad to the phone and you can reply comfortably to e-mails;
  • You can transfer files between a USB memory device and an Android device using a cable;
  • If you connect your smartphone and printer using an OTG cable, you can print files from your smartphone;
  • when you connect the mouse, you will be able to use it instead of the touch screen;
  • if you are a busy player, you can connect the gamepad to the cell. In this way you will gain better control over the course of the game.

Does OTG work on all phones?

At this point, more and more smartphones already have this function. However, if you use an older phone model or you bought a phone called budget, you have to reckon with the fact that it may not support OTG.

Most new phones and tablets automatically support the on-the-go function. How to verify it? The easiest way to check it is after purchasing a new device. Typically, the information is on the packaging. You must find a special logo from USB ON-THE-GO. If you do not have the original phone case, nothing is lost. Android phones can be easily checked using a special application available on Google Play, eg USB OTG checker. After installing and launching the application automatically checks the OTG availability in the phone.

What does the OTG USB cable look like?

Each phone has a micro USB port, which is primarily used to connect the cable and charge the smartphone. You can also connect another peripheral device to the Micro USB port. However, to be able to use such a facility, you must have a special cable. In this type of cable-OTG adapter on one side is the input for a full-size USB plug, and on the other - the output from micro-USB. The costs of such an OTG adapter are different and depend on the "advancement" of the cable (eg number of branches, whether it has a power supply, etc.). In any case, this is not the price that knocks off the legs. For this reason, it is worth having a cable in advance, especially when planning eg a longer trip for a holiday without a laptop.
