Or put no animation at and get NO lag.

This is my first smartphone EVER and after tinkernig it for a month I have pretty much uncovered everything about this phone.

The thing about android phones is that you have a LOT of freedom, and I mean a LOT. Which is why I'll never support a company like apple. It's not hard to learn to root and mod your phone to your liking with a bit of research which makes you able to completely customize your android to your liking. With the s4, it is almost impossible to brick your phone unless you are a complete idiot (knock on wood though hehe)

Anyways here are some tips to make your phone extremely fast. I had some help in this thread so now I want to give back.

1. Root your phone first (this part is very very easy, canadian models have probably the easiest way to root there phones)

2. I advise everyone to learn how to flash there roms. I thought this was hard at first to, but again its VERY easy. Just download Rom manager after you root your phone. Everything else should be common sense or read a couple threads back for instructions. Choose a rom from the xda forums. I personally love roms that are debloated and is optimized for speed and battery.

3. After you choose your rom flash a kernel. The BEST one right now is ausdism kernel. Has the best battery life and speed optimizations. Look it up on xda forums again.

4. To further lower your lag, or TOTALLY get rid of it, and make your phone the fastest phone in the world, download a different launcher, SPECIFICALLY NOVA as I think its the only one that has the option to change the speed animations. Look and feel > scroll speed and animatino speed > put it to "faster than light" Oh and make sure to put no animation like I said earlier in developer options instead of .5

You now have the fastest and lag free phone on the internet. Doing these settings my phone is completely lag free. All my friends are amazed at how my s4 is 1000000X faster then there s4. It's not even a contest. It's even more faster then my gf's iphone5.

I've also managed to get my battery life to 6+ hours screen time with 1day15hours in total. Pretty amazing if you ask me.

I much prefer TW roms now as the GE roms are pretty unstable as it's still based off TW. You also lose a shit ton of features. I will have to try again with 4.3 though, hopefully they will optimize it more and some develeopers create a godly rom for it. As it looks like right now 4.3 seems to be pretty good. The leak is terrible though. TW has the best features IMO, so just make sure to get a debloated one.

Another thing someone said they wanted the TW camera for GE. I think there is a mod for that somewhere on XDA. Nevertheless I think the GE camera is way better.

Does ausdim's kernel allow you to change the colors? One reason I stick with using Ktoon's kernel is that is has trinity colors option which allows me to make the colors more 'colder' (whites are more like a brand new white t-shirt than a white t-shirt that has been worn many times, haha). I don't like Samsung's factory settings cuz it makes the screen more warm and 'yellowish'.

Is it normal to lose 15~20 percent over night with everything turned off and power savings turned on?
This phone seems like a huge battery hog.

Nope. Something is causing wakelocks that is preventing your phone from deep sleep. I only lose 1-4% on my phone overnight.

Has any one killed their MicroSD card yet? Not even 3 weeks old, my SD memory card died.

Seems like a common problem.

Was it an AData card?

I have a 32GB AData card and it died after 3 weeks in my S4. I know of a few other people who had their AData cards die in a short period of time too. All different kinds of Samsung phones.

I didn't have any problems with my other cards in the S4.

My friend warned me about the problem after I mentioned I picked one up. It's a good thing I didn't trust the AData microSD card with pictures.

Dropbox with auto upload saved all my pictures. Good thing the S4 comes with the 48GB bonus.
