You can select your favorite device from a wide variety of candidates and customize it to a high degree, which is the appeal and strength of Android. However, on the other hand, it is often pointed out that it is difficult to understand. In this section, we will explain such "I don't understand here on Android" in an easy-to-understand manner. This time, I will answer the question "Can I connect a USB keyboard to my smartphone?"

In conclusion, it is possible to use a USB keyboard on an Android device if certain conditions are met. With a Bluetooth keyboard, there is no occasional disconnection of communication, and there is no need to worry about power supply such as battery arrangement and battery level, so it is an effective option for users who emphasize writing. You can also meet the needs of using the keyboard you are used to using on a PC on Android.

When connecting a USB keyboard, you need an adapter to convert "Micoro B male" to "A female". It's sold for a few hundred yen, so the introduction cost shouldn't be a problem. Some devices may limit the use of USB keyboards, but many devices can be connected this way. However, while using the USB keyboard, it will block the charging terminal and consume a small amount of battery, so be careful about the battery level on the Android device side.

If your device is Android 4.1 or later, the USB keyboard will be recognized just by connecting it via the conversion adapter. After that, if you set the appropriate keyboard type and keyboard layout on the "Language and character input" screen from "Settings", you can use it as a keyboard with an application that supports character input. Depending on the keyboard, you may need to use the keymap published on Google Play such as "Japanese 106/109 keyboard layout".

When you start using a USB keyboard, the software keyboard that occupies nearly half of the screen may start to feel annoying. In that case, install an IME app that hides the software keyboard. In the case of ATOK, if you check "Prioritize hard keyboard" on the setting screen, the software keyboard will be automatically hidden when the USB keyboard is connected, so it is recommended.
