solution to reduce the lag on your GT7.7

[bassem.mohsen]

WARNING -- you may try this on Jelly bean only, as ICS and HC are not protected and might lead to BRICK bug

Hey All

I noticed that after we made a factory reset our device is extremely fluid fast and smooth
but after couple of days it starts to lag, and continue to lag more and more.

I found that the problem is Storage performance is decreasing overtime due to not wiping and trimming the blocks that we don't use.
This is a famous problem and discussed here: http://forum.xda-developers.com/showthread.php?t=1971852#fm
even google fixed it on Android 4.3

Just try this application and tell me, how did you find you device state now?
https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix&hl=en

and you can benchmark it before and after

Thanks all

WARNING -- BRICK-BUG

OP, for certain devices, the app developer has stated BrickBug means DEATH of your device if you try LagFix!

http://forum.xda-developers.com/showpost.php?p=37029420&postcount=122#fm

There maybe users with SGT 7.7 models still running stock HC/ICS kernel (edit: unpatched) and recovery, so potentially at risk.

Cheers,

Anyone try this yet with the 7.7?

I'm running Jelly bean now, I didn't faced any bricks
do you think it might happen for me too? should i remove the thread?
and why trimming an unused block in memory will lead to brick bug?

As far as I'm aware, JB is not faced with the brick bug. I was warning about previous Android versions. Have a read of the XDA thread I linked, can explain things better than I ever could.

No, I think this thread is ok, but maybe make reference to JB only in thread title etc and possible brick warning if used with other.

Edit: I see you put a warning in OP, thanks.

I am using PA 3.68 on a P6800 - Laxfix will not run - states device not supported for /system /data /cache. this is to bad as looks like could be a helpful feature.thanks for sharing and hope it works for others. I go back to the referenced thread and see if I need to make some other adjustments.:fingers-crossed:

for real, and i tried it several time, it restores the speed of the device to the day i made factory reset.
it's not placebo and i benchmarked before and after, and the topic above also shows benchmarking.
and even reviews of Android 4.3 talks about trimming and how he removed sluggish from N7 first Generation.
Anyone with JB are welcome to try it.

I miss PA android BTW and the feel of nexus on my device
when Android 4.3 based ROMS are out, I will flash it.

Does not work. Do we have to be rooted?

yes, the application access the system, data, cache partitions to tell the memory that this block is empty now, don't exert effort in maintaining it.
so you to be rooted yes, and on JB for Safety.

Doesn't work

Im on stock ICS 4.0.4 XXLQ2, rooted, with custom EZYKernel XXLQ1, no brick bug.

LagFix doesn't work because

fstrim: FSTRIM: Operation not supported on transport endpoint

I tried it with /system /data and /cache with no luck.

My friend, you have "b**ls of steel" (if you're a guy). I'm not entirely sure his kernel is entirely safe. In addition to removing the "mmc cap erase", there needs to have a patch applied as well.

From what I remember,... the brick bug known to occur with unpatched kernel and stock recovery with HC or ICS firmware.

Even with my patched kernel, not sure exactly if it'll be 100% OK....


Edit: just worked up the courage to test with my "protected" SkyHigh kernel v2.9.1, and as thought, app does not work

works good for erobot..
ive been on 2.3 with multiwindow mod and for some reason its been laggy lately.This app works good and faster now.was going to flash back to stock JB kernal again but now looks like this has fixed it..

Yes I am male with b**ls of steel and i raped my P6800 many times. I know what I am doing and i'm familiar with my hard and software.
If your Kernel is avaliable with 3G Support, I'll give it a try. My P6800 is my every day Phone/Multimedia device and act also as a laptop replacement, with native Debian on it.
If I wreck it, it was my failure and I didn't cry for my mom

I must say, I tried your app for fun because I don't have any lags on my device. I have no need for "Project Butter", I use ADW Launcher ex, 268 Apps for IT Administration, Produktivity, Games, Multimedia. If I feel an app opens slowly it's time for "fschk" the Partitions. After that everything works fast and smooth as before.

Have you ever been touched by the "brickbug" with stock recovery or kernel/ROM from Samsung with your P6810 ???

Not this again..... :beer:

BTW: I've never actually factory reset etc using the stock recovery, and suppose never going to get the chance .The app developer also made reference to various bricks using his app caused by brick-bug affected devices.

Samsung themselves have signed off the patch (amongst others), so good enough for me. Just a shame that I don't have the option of using this app (safely) unless I use daniels custom JB ROM.

I've had this program on my P6800 for some time now. It has been a blessing, and even upgraded to the Pro version.
It certainly feels snappy like Jelly Bean was just installed. I've set it to do a trim once a week.

Using JB 4.1.2

OT:
How are you running native Debian on P6800? Could you post a simple guide how to do it?

Android 4.3 do it everyday with the following event:
device is left without activity for one hour
device is charged within 30 - 80 perecent
24 hour from last trim have passed.

Yes THIS again ! opcorn:

I never ever got the brickbug with my P6800 even though I always used Stock kernel from Samsung on it... I might have iron b**ls when I switched from HC to ICS, then from ICS to JB with a supposed affected device and with various factory resets...

 

[B4R7H]

its safe if i use this on ur kernel UITA? v 3.3.0 JB
