How to know if my Android smartphone is OTG compatible

You want to buy an OTG adapter to connect a USB key to your smartphone or tablet? You can find them for less than 10 euros on e-commerce websites but before you do, you’ll have to check that your Android device is OTG compatible.

Connecting a USB accessory to your Android

Android is a very open and flexible mobile operating system. It has quickly established itself as an absolute reference in the small world of mobile OS. No less than 7 out of 10 smartphones are equipped with this software.

Photo, personalization, widget, multitasking, Android smartphones have many assets. But if there’s one area where Google’s OS shines, it’s storage. Most Android phones and tablets have a MicroSD card slot.

Last but not least, Android supports all kinds of USB accessories. For example, you can connect a mouse, keyboard or removable hard drive using an OTG connector.

This is convenient in many ways. We all know that storage on Android poses huge problems. The latter quickly reaches its limits when you take a lot of pictures with the camera.

With the USB OTG function, you will be able to connect a USB key or a removable hard drive and transfer your photos. You can also use this device to connect your phone to an SLR camera and use the mobile’s screen as a viewfinder.

But before you rush out to buy an OTG connector, you need to start by making sure that your Android phone or tablet is compatible with this type of technology. And yes, not all devices are equipped with the drivers (computer program) necessary for the proper functioning of the OTG standard.

If your mobile device does not support OTG, it would be a shame to buy an adapter or a connector for nothing. As a reminder, USB On-The-Go (OTG) is an extension of the USB standard that allows two devices to exchange information without going through a computer.

Use an OTG compatibility tester

To find out if your Android device supports USB OTG, you have two options: look for the certified USB On the Go logo on the box your phone came in when you bought it.

You can also install a free application called USB OTG Checker. As the name suggests, it will check if the USB port on your device is compatible with OTG connectors and cables.

Now that you are sure that your tablet or smartphone supports USB OTG technology, all you have to do is order an OTG connector. Any USB accessory can be connected to Android as long as it doesn’t require an external power supply.

If you want to be able to connect a mouse, key or hard drive while charging your phone, you’ll need to invest in a powered OTG cable. This device can be essential to connect a removable hard drive. Indeed, this type of accessory draws its power from the USB connection. Unfortunately, the port of tablets or smartphones does not deliver enough power for the hard drive to work properly
