In fact, the new GPU drivers in stock ROM 4.3 did boost up the graphics performance. My Asphalt 7 used to laggy on 4.1.2 or 4.2.2 but now smooth like butter on 4.3. I don't face any problem with Samsung keyboard so far but wake up to the lock screen is the real pain AND i lost Miracast support due to lack of HDCP support. Overall performance still ok provided disable all the dumb *smart* feature and S Voice.

I'm still thinking whether to flash it to CM10.2, any one did that? mind to share whether worth to go for it? coz a bit lazy to backup and flash again. Thanks.

Thanks for that....after flashed Yank kernel....lock screen delay seems ok. Now the only thing need to be work out is the Miracast problem.

Thats apply only for vanilla kit kat though, don't think thats apply for Samsung stock ROM. Samsung usually will put in some trash to consume more memory compare to vanilla ROM. Thats my personal thought

Actually I'm quite impressed by the iPhone 5s with iOS7, it performs like butter liquid especially touch responsive that i ever seen from any of flagship now. Even Samsung Note 3 will be having lag problem after few weeks of usage that claim by some owner. thinking of to get one iPhone to play around....never been explore iOS

I believe people who play gadget will try to explore and experience any kind of products but not limit to certain brand or to be a blind fans, right!

Does anyone tried this already?

Just patched...
Lock screen delay sometimes is 1 seconds delay but mostly it can goes instant on....not sure about battery life

No performance different between Yank and this....and it should not require to be root. To me benchmarking it just a figure shown it doesn't have noticeable performance boost for normal usage. I don't have it install but you may try it and let us know.

kanasai lor....if like that

Can you share the differences?

Note 2 still consider a leak ROM but S3 one already is official release. Samsung should have tested before it goes official right! but looks like they did not

That is why I already ordered my Nexus 5, no more Samsung flagship phone for me. Been support Samsung from Galaxy S, SII and SIII and believe that they could really evolve to be a strong software oriented company, to be the fastest phone that get Android OS update, to be the most responsiveness Android phone ever but Samsung keep on disappoint me so I decide to jump ship.

By the way, do you guys notice that the new gallery (in 4.3) usually took 3-4 seconds to open up? What a crap software...

I ordered 32GB, storage wise should be ok according to my daily usage (music, photos & videos, games and movies) and most of them can be store on the cloud nows a day.

Thanks...but not dare to give it a try

Ya...I'm also reluctant to go back 4.2.2 although new Gallery damn slow to execute and miracast not work anymore. However still smooth when playing games.

I like this.....people's wife always more HOT

You got your points

Bro...may i ask something on CM 10.2 temasek? If I'm currently on stock 4.3, is there a risk to lost IMEI and not network coverage problem if I flash it to CM 10.2 temasek?

How about from Stock 4.3 -> CM 10.1 ??

Thanks bro...I'm on it now...very fast ROM....just manage to settle TB not able to restore problem....will keep my eyes on it.
