End of the day, what are the real difference between the S4 on 4.2.2 Touchwiz, vs this new 4.3 Touchwiz ? Just running stock rooted, no custom ROM or anything. What are the noticeable differences ? Does 4.3 TW update remove the lag I feel on my S4, is the phone smoother now ? Any better battery life ?
And lastly whats the best way for me to get the update ? I am currently rooted on the stock 4.2.2 OS, I used Kango root last month for my root, but I also deleted every single ATT .apk using Root Explorer, and a handful of Samsung .apk's also removed, pretty sure I deleted the update .apk, need to find that from a ROM and install as a .apk ?
