A small percentage of Android users may be suffering Angry Birds withdrawal, but not for long.

Rovio Mobile, the developer of the bestselling Angry Birds app, has announced that it is developing a lighter version of the game for "lower end" Android devices after many users experienced problems running the app.

Rovio had released a free, ad-supported version of Angry Birds for Android on October 15 through independent app store GetJar. It was so popular on the first day it brought down Rovio's servers, and hit the two million download mark within three days.

But many Android users were disappointed to learn that the game didn't work on their phones, an issue commonly known as "fragmentation." Older and lower performance Android devices experienced "severe performance issues," Rovio acknowledged in a blog post.

Rovio listed 17 Android phones officially not supported by Angry Birds, as well as devices running a version older than 1.6 or custom ROMs. The list includes newer phones like the Sony Ericsson Xperia X10 mini and Motorola Backflip.

"So far, we have hesitated to create multiple versions of Angry Birds for the Android platform. But judging by the feedback we have received, we feel that by providing a lightweight solution, we are doing a favor for our fans," Rovio wrote.

The company hasn't announced a release date for the lighter version.
