Still don’t have USB OTG cable? Then you are not getting all the features out of your Android devices. Of course, your Android devices need to support USB host function in order for you to use USB On-The-Go. It enables USB flash drive, mouse, keyboard, joypad or any USB peripherals that support USB OTG on your Android devices. My Samsung Galaxy S II, Amazon Kindle Fire (using custom ROM), Samsung Galaxy S III and Google Nexus 7 support USB OTG. It is ashamed that HTC One X does not support USB OTG natively. Not going to install custom ROM (which supports USB OTG) until S-OFF for HTC One X is available…
USB OTG cable has lot of usages. And it can used on Android smartphone like Samsung Galaxy S III and Android tablet like Google Nexus 7. Besides connect it to Logitech Wireless Gamepad F710 to play games, I use it to connect to Samsung Galaxy S3 and Nexus 7 with Logitech Stereo Speakers Z110 for music and video. Logitech Stereo Speakers Z110 is a USB powered speakers. A perfect combination with Samsung Galaxy S3 and Nexus 7 due to its compact size and can draw power from the devices themselves.
Google Nexus 7 does not have microSD card slot. Adding extra SD card to increase storage space is not an option. You will face low disk space issue sooner or later especially for those with 8GB storage model (like mine). My Amazon Kindle Fire serves me well even with 8GB storage only. However, situation is not the same with Nexus 7 because it supports lot of interesting Android games with NVIDIA Tegra 3 GPU. And most of these advanced 3D games require lot of disk space. Luckily, I manage to put most of my music, photo and video on external storage like USB flash drive. And connect it with USB OTG cable when needed. Of course, with the help of StickMount application too. Note – root access is required.
