Anyone who has owned either the SGSII or SGSIII and been involved in rooting and modding, will surely know the name of the developer JKay and of his Deluxe settings. Basically, what JKay offers is an alternative framework for your existing, rooted, firmware. Into this he places a whole host of options to modify and improve your phone... some of which, I might add, seem to have crept into the S4 from the S2 JKay release. These frameworks are phone model and firmware specific. He will not be supporting the i9500. At the moment, the good news is that during his alpha testing stage, the JKay Deluxe settings .apk is free, (probably have to pay for the official release), to use with his only test release so far for the XXUBMEA or MF8. You will need to download and install 3 files... Deluxe settings .apk JKay XXUBMEA/MF8 framwork .zip Restore XXUBMEA/MF8 framework .zip You will need to be rooted and have a custom recovery installed to flash the .zip files. WARNING: At present, this is an, "alpha", test from JKay. Only suitable if you are running firmwares XXUBMEA or MF8 and are competent with flashing and modding. I would strongly advise doing a nandroid, Titanium and efs file backups before thinking of embarking on this. For more details, instructions, screenshots and downloads, see posts #1, #2, #3 and #4... http://forum.xda-developers.com/showthread.php?p=42350896#post42350896 On the plus side, it is good to see that JKay is supporting the S4. :thumbup: Personally, I shall sit back and wait for the release version.
