    Wow is what we could say after seeing the custom ROM applied. But when games like death dome are played it takes very long time to load and then closes automatically. Small games like Temple run stuck in between. Pls suggest. This happens in both Remics and Jellybam.

    I installed it and it looks great in my i9003. Well there has been issues with wifi and usb tethering with every custom rom and this rom is no exception. Gtalk crashes sometimes, but I can handle that by using some other apps. Google Now in i9003 is great thanks to Pradeep Neela. Battery drains very fast and I am charging my phone three times a day. Please fix it in the next update. I am looking forward to it. Thanks again.
