LeWa OS is a new Android 2.3.7 Gingerbread custom ROM that seems to have appeared on the radar of many custom ROM developers, as it has made its way onto 2 or 3 devices in a very short span of time. Now, LeWa OS has been ported to the Galaxy S, thanks to XDA developer barome. LeWa OS combines CM7 and MIUI ROMs, and provides a blend of features from both. Some features include data monitoring, downloadable themes and lockscreens, power saving, lockscreen animations and notifications, and more, along with fast performance and smoothness.

So, get your Galaxy S out and read on to find out how you can install LeWa OS on your Galaxy S i9000. Oh, and don’t mind the Chinese text in the image above, the ROM is in English.
