    What about camera colors ???

    I have tested and have to say, GREAT rom, MULTI-LANGUAGE ( almost all language ) and the camera app is actually pretty good without the blue problem, although the pictures come out a bit dark !

    So far the best 4.2.1 rom for our device, i am using with touchwiz launcher and it runs really smooth


    Thank you for the great work !!

      Additional information:

      A few apps stay in Chinese even after switching language, only SYNC for gmail, NO calendar, contacts etc. 

      I think most people will need the Sync function to be fully working,

      Some of the chinese apps, if you check in SYSTEM / APPS folder using root explorer,  are in english there and can be replaced with english versions from play store

      Potentially this could be a perfect rom, just a few basic functions need adding / tweaking and it will be a daily driver !!!

      in the app drawer are 2 little cog icons, one of them is settings which is tabbed, under one of the tabs is an icon which is a white square with the letter A, click this and then click the very top it will open up your languages

    The rom is not perfect. Blue screen after camera use and black photos.

    I installed 4.2.1 alternative 1.5. find it on 4pda. No blue screen and very good photos

    Is tis AOSP?

    Have been using this rom for a few days now, overall works really smooth, fast and without any major error, the previous comment i made about no sync items except gmail, is easily fixed by flashing GAPPS with the rom at the beginning, and everything will sync now !!

    As for camera, have had no issues with blue screen but have tried a few different camera apps to try to get around the dark pictures but still the best for me, quality wise is the camera from stock with gallery, it focuses properly and the photos were slighly brighter, adjusting the contrast and bright setting helps a little also !

    The major down point for me and is only personal taste , is the samsung interface, if i could take this rom and make it look like s920 roms, i would but only know how to change the launcher not the framework !!

    Thanks again for the rom, definately worth the try, good enough as a daily driver for me !!
