OTG Help Guide for Android Users
What is OTG ?
USB OTG is short for USB On-The-Go. With USB OTG you can connect your Android smartphone or tablet to external USB devices via the charging port.
All Android phones running Android 3.1 or higher support OTG. This free USB OTG Checker App makes it easy to test whether your phone is compatible with any USB device that can be plugged into USB, USB-C or Micro-USB port of your smartphone.
Install USB OTG Checker via Google Play
Before using SmartMic™ Type-C with some Android smartphones you need to enable OTG in your settings. This allows your phone to pick up SmartMic's receiver and then change the default internal microphone to an add-on external microphone, in this case SmartMic™.
This video shows how to do this on the RealMe X55G handset.
**PLEASE NOTE** Due to the vast amount of Android handsets available the menu settings for enabling OTG and external microphones on your handset may be slightly different than in this example. If you are experiencing difficulties please refer to the user manual from the device manufacturer or e-mail email@example.com for further assistance if you have Priority e-mail and Technical Support.
