The LG Nexus 4 may be considered by some people as the latest and greatest Android-powered device to date, but the truth is it's far from perfect. In fact, it has a number of flaws that many users have gripes about. One such flaw is the lack of support for USB OTG, an important feature especially for all those who frequently rely on third-party accessories and external storage drives. Since neither Google nor LG plan to fix this USB-related issue, user CaptainMuon over on the XDA-Developers forum has taken matters into his own hands.
After putting in a bit of manual labor, CaptainMuon succeeded in enabling USB OTG on the Nexus 4. And now he is sharing the results of his work with the rest of the world. Apparently, all that's needed is to supply the necessary 5V to power whatever USB device gets plugged in and then to activate USB host mode on the Nexus 4 manually. It sounds simple enough, but it still requires a bit of careful tinkering and the ability to follow instructions.
Here's a video that explains the USB OTG hack for the Nexus 4.
