Developers have helped address this issue by introducing applications that allows users to take their PS3 controllers and connect it to their phones/tablets/etc. But there’s still the problem of properly positioning your device. While kickstands are beneficial, gaming can still be chore if you’re hunched over with your phone on your lap when laying in bed.
The design is so simple, yet so genius, most of you are no doubt kicking yourselves for not coming up with it first. Keep in mind, there are a few caveats. One — you’re going to need a rooted phone if you hope to use your PS3 controller wirelessly. Two — there is a non-root version of the GameKlip that includes a USB cable but only some devices will work with it out of the box (the Samsung Galaxy S3 being one of them). If you phone isn’t on GameKlip’s list, there’s no guaranteeing your device will be compatible.
To better show you guys how the GameKlip works, here’s a quick video from the inventor giving a little more detail.
