That 4.3 Lag...

[Mykltron]

Since that awful 4.3 update my phone takes 3 or 4 seconds to wake the screen and sometimes some of the icons are missing for another second, or they'll disappear for a second after waking. Is there any way to speed this process up? Would one of those CPU control apps do this? (yes, I'm rooted) Nothing else is slow.

 

[funkylogik]

A cpu app wont do anything useful unless you flash a custom kernel. Have you tried a 3rd party launcher? I recommend Nova Launcher :thumbup:

 

[Mykltron]

Is that going to sort that lag then? Can I use the stock icons with Nova?

 

[funkylogik]

Its worth a try.
Not sure about the icons but theres thousands of icon packs.
Plus Nova has an option to import your current layout so its pretty painless switching and you can always go back to the stock launcher :thumbup:

Thanks, I'll give it a go.

There is a patch available that resolves this issue.

Look thru this tread http://forum.xda-developers.com/showthread.php?p=48354301#post48354301

Oldnick, are you saying that if I change my baseband version from XXUGMJ9 to I9300XXUGMK6 with the .zip downloaded from here:
Firmwares | SamMobile
my phone won't have the lag mentioned in the OP?

Is this an official update?
How do I install it?

 

[Mykltron]

Seriously, how do I install it? Is it risky? I read through that thread but I didn't understand any of it. This 4.3 lag is really pissing me off now.

 

[Muilisx]

Did you factory reset after the update? That's known to fix everything.

 

[oldnick]

I installed it and it certainly resolved the lag issue for me.

If I recall I put the zip file on the phone and used recovery to install it.

I'm not a big phone hack so if I can do so can you.

Good luck!

PS - I didn't need to factory reset, it just worked fine after reboot

 

[mydian]

I'd make sure that's for your exact model first before you flash that.

 

[funkylogik]

^this!

The update actually stopped my phone from working and I had to send it away for repairs. It came back factory fresh, so someone did a factory reset.

I shall give it a go later then. And yes, I've checked multiple times (and shall do so again!) to make sure it's the right version.

First of all there are no significant differences between lag experienced on a stock ROM to a custom ROM, even with a custom kernel. In my view, all perceived improvements are very marginal and seem to detract from the real issue, which seems to be processor related and linked to the JB 4.3 system builds that Samsung issue.

If you look around most people experience lag with JB4.3 based ROMs on Samsung models with the Exynos processors but hardly any with models using a Snapdragon. I have two Samsung Exynos based phones, a Note 2 and a S3 and both struggle to a greater or lesser degree with lag, irrespective of ROM (stock based or AOSP/AOKP/CWM) and custom kernels. Since 'upgrading' to JB4.3 I have never been able to completely eradicate this problem. In that regard, JB4.1.2 was miles better.

Im on jb 4.3 s3 i only experience the lock screen it took time to get back
i tried factory reset ok after a weeks and its back again

 

[Mykltron]

I tried installing from internal memory and SD card and it always said 'aborting installation'. So far, however, waking the screen seems to happen rather fast.

I tried a Nandroid backup and factory reset yesterday. It doesn't seem to have fixed anything and when I restored all the data it didn't put it back in /emulated/0 but instead put it in /emulated/0/0, which meant I had to bugger about putting everything in the right place. Fun. Tech doesn't like My-kl.

Restoring a nandroid after a factory reset is kinda pointles mate because it puts everything back how it was. Best to use Titanium etc to backup apps, do the reset in recovery so that it only wipes apps and their data, then restore them with titanium :thumbup:

I had the same problem wgen I upgraded to 4.3 a couple of days back....
While searching on net I found a simple tweak that solved the problem. Dont quite remember where I found the solution to give the credits.
Just goto developer options from settings and change the value of Windows animation scale, Transition animation scale and Animation duration scale to 0.5x each

Funkylogik, I wondered if Nandroid would do that...

Thanks. I've made the changes. I'll see what happens over the next couple of days.

 

[Mykltron]

Well that totally failed to achieve anything. I've now done a factory reset and reinstalled everything manually. I look forward to discovering I've wasted my time over the next few days...

Aw...but is was so fun

Looks like the factory reset made it slightly faster. It tends to respond faster when the screen lock is on than it did before so that's the main thing.

I had the same issue, noticed two apps were hogging allot of RAM, uninstalled and adjusted my animation to .5 & off accordingly. Have you tried clearing dalvik cache since your rooted?
