I am wondering if the coloured emojis, if there are any in the leak, are Googles odd looking ones or if Sammy has made a few of their own?
the emoji,s look like this in s4 leaked 4.4 Samsung 19505 Stock ..
you can get rom by omega made from the leaked rom. here. works a treat .
Here you go, this is the file located in /system/fonts on my Galaxy S3 running [ROM][AOSP][4.4.2][KOT49H] SuperNexus 4.0 - I9300 - Build 1 [25-12-13].
It is just zipped up and NOT for flashing. Don't forget to set the proper permissions and backup just in case!
