Hmmmm yeah that happened to me. Next reboot it should be quicker. .. No idea why this happens
[Galaxy S 4 Themes and Apps] gorgy76:
Tried your latest app. Still 0kb in used here. :( using shostock. Cleaned everything reinstalled and still values not sticking.
[Galaxy S 4 Themes and Apps] hypergamer1231:
Just out of curiosity will the stweaks problem be fixed by you or by wanam ??
[Galaxy S 4 Themes and Apps] rlorange:
Reboot again and wait like 10 minutes I's magically come alive for many. .. fickle eh? Grrrr
[Galaxy S 4 Themes and Apps] rlorange:
Ill have a look but there is nothing direct that my app does to break it and I don't have the device to test so if Wanam can help that would be great.
[Galaxy S 4 Themes and Apps] rlorange:
Ok so the next version will have companion set-on-boot app which you can install and use instead of the init.d boot. It will take up only 10MB of memory and ac running service. Hopefully it will work with S-tweaks
[Galaxy S 4 Themes and Apps] rlorange:
Did you try a second reboot mate? For some reason it sometimes needs a second reboot and time to settle for it to work. I experienced this myself during testing but it DID eventually start working and the delay disappears permanently.
[Galaxy S 4 Themes and Apps] Moz007:
I have MH8 stock rom with KT Kernel 9/17 and CF-Auto-Root and Busybox 1.21.1-Stericson in xbin.

I try to reboot 20 times and nothing happened.

Still not applied on boot and still have the "0 kb" bug...

Please, help ! :crying:
[Galaxy S 4 Themes and Apps] rlorange:
How frustrating for you.

Remember this: If setting the swap fails at any time, on boot for example, then it will stay broken with the 0kb bug until you reboot twice after removing the boot script.

Try:

#1 removing boot script.

#2 power phone off.

#3 Reboot.

#4 reboot to recovery.

#5 reflash kernel

#6 reboot and wait a few minutes after boot.

#7 run Turbo zram and set a swap.

#8 play with your phone for more than 10 minutes. Check with "I" button if it's working.
[Galaxy S 4 Themes and Apps] rlorange:
I experienced the 0KB bug myself swapping between KT versions and quickly realized that there was some pattern... WHY on earth you need to reboot twice and then the swap delays being run for 10 minutes I have NO idea.

However once it does start to run the delay is gone for good...

May I suggest you flash wanam lite MGA deodexed? Since this is the ROM I develop on.
[Galaxy S 4 Themes and Apps] Moz007:
I really thought but no, it doesn't work.

I think I'll give up.

[Galaxy S 4 Themes and Apps] rlorange:
Which ROM are you using? Seems many on your device variant have an issue. KT assures you that the kernel source is identical. So something else is breaking it. Also if you could take a screen shot of your init.d folder or even zip it and post a dropbox link it will help be debug.

DOWNLOAD LATEST: V2.1d

===============================

UPDATED V2.1d (app only for now)

2.1d> Reworked the command. Discovered that the KT auto zram setup has broken permission for the /sys/block/zram0 simlink. App will now fix this and runs WAAAY Better for me.

PLEASE REMOVE YOUR BOOT SCRIPT VIA APP. REBOOT TWICE. THEN RUN THE LATEST VERSION AND RESET YOUR BOOT SCRIPT. PLEASE LET ME KNOW IF ANYONE GABBING THE OKB BUG FINDS IT NOW FIXED

[Galaxy S 4 Themes and Apps] Moz007:
Not working, same as previous version...
[Galaxy S 4 Themes and Apps] rlorange:
Ok Thanks but I'm close to solving it.

The problem is the default 400mb swap that KT sets. It uses some embedded commands and if switched off the wrong way leaves the device broken. I've figured out half the riddle.

Please with the new version.

Delete the boot script

Switch phone off

Reboot and wait a while before you launch the new app. Then set.
[Galaxy S 4 Themes and Apps] bubblebuddyi:
Tried the new version, still not working for me :(
[Galaxy S 4 Themes and Apps] rlorange:
Back to the drawing board I guess :(
[Galaxy S 4 Themes and Apps] dave_p_b:
Tried the new version and it was working on latest KT kernel and Omega V12, following the instructions in the OP. I noticed the amount of zram being used would go up, and then would go back down after a deep sleep. Not sure if that's intended behaviour. Sadly I can't use it all the time as every kernel apart from Adam1.6 gives me scrolling lag in TW.
[Galaxy S 4 Themes and Apps] bubblebuddyi:
I'm not sure if its just me having a problem or what lol.
[Galaxy S 4 Themes and Apps] rlorange:
The latest version I'm working on has improved lag massively for me. I've improved the command structure which

Seems to have improved the overall performance... Stay tuned.

The latest version waits for the default zram to kick in in KT before reseting it. This was causing asynchronisity and lag I think.
[Galaxy S 4 Themes and Apps] dave_p_b:
The TW scrolling lag is odd. It's not there all the time but it tends to happen most when the phone has come out of deep sleep. So far I haven't found anyone that could explain it and not everyone appears to suffer it. It will be great though if the turbo zram can go some way to reducing it. Thanks. :)
[Galaxy S 4 Themes and Apps] rlorange:
I'll post some v sys ctrl tweaks to try
[Galaxy S 4 Themes and Apps] bobdoblo:
Anyone?

Sent from my GT-I9500
[Galaxy S 4 Themes and Apps] dave_p_b:
I can't imagine you would see an immediate difference in your RAM usage. I think you will notice performance benefits during heavy multitasking. Plus when you have a lot of apps open you may see it uses less memory overall.

That's my understanding anyway :)
[Galaxy S 4 Themes and Apps] rlorange:
No you won't because Andriod memory management will still run as normal.

However the total swap created by Turbo ZRAM is compressed so some of the cache managed by normal Android stuff is taking up 2/3 less space than normal.

Also for reasons unknown Samsungs way of doing this memory stuff is vastly improved with this mod.

The boated TW stuff that you rerely use is given a higher priory to stay cached in RAM so when you multitask the apps you actually want to stay active are killed before TW crap you rarely use. My app seems to cache this TW stuff so while it sits there in RAM it takes up less space meaning the stuff you use isn't killed as often
[Galaxy S 4 Themes and Apps] rlorange:
Spot on mate! Zram has been around for a while but the mod is the first to run 4 parallel swaps.

With just 1 zram disk running the performance I/O penalty was annoying with 4 running in parallel there is virtually no performace penalty.
[Galaxy S 4 Themes and Apps] rlorange:
Heres some info:

"Each zram device contains it's own compression buffer, memory pools and other metadata as well as per-device locks. This can become a serious bottleneck for multi-core machines. To work around this problem, zram is capable of initializing multiple devices. The recommended amount of devices for swap is 1 per cpu core."

This inspired me to make this mod

[Galaxy S 4 Themes and Apps] RivalComp:
I also installed as described but the system doesn't use any of the swap. 0k... no more. :(

Latest KT, Samsung stock TW.
[Galaxy S 4 Themes and Apps] rlorange:
I wish I knew why some of you are experiencing this issue... Always uses lots of swap for me and most others
[Galaxy S 4 Themes and Apps] RivalComp:
I think I've found the problem. I think you should correct permissions not just on zram0 but also on zram1, 2 and 3. In my case there were no write flags on these folders. In zram0 the disksize hadn't got read flags by group and others as in zram1-3.

One more thing to correct in your script: please add an initial '/' at the start of the system remounting line. When I started your script from command line, system partition could't be remounted because the path was wrong.

/system/bbsiyahmods/busybox mount -o remount,rw /system;

(Why this custom busybox is necessary? You don't use custom busybox for remounting root but for remounting system. Why?)
[Galaxy S 4 Themes and Apps] devilpera64:

[Galaxy S 4 Themes and Apps] AndroidGX:
Hi rlorange !

I just made THIS modification into my own kernel but your app still says me that I don't have the necessary module to accepts 4 zram.

Do I need to do anything else ?

Many thanks in advance :good:
[Galaxy S 4 Themes and Apps] rlorange:
Ah... Im no kernel Dev but KT used the same source from googy in his latest so I based my app on the setup from that.

Look in /dev/block you need the 4 x zram devices there. If they are there then you should delete:

/sdcard/Android/data/turbozram so that my app redetects your setup.

If they are not there then something is amiss and your kernel is not setting up the devices
[Galaxy S 4 Themes and Apps] AndroidGX:
Thank you ;)

Looks like deleting "/sdcard/Android/data/turbozram" folder was enough to make the app detecting well again 4 zram :good:

mod is working as-is

Hey rlorange. I am here to report back that the mod is working. I read through the thread and saw that some people had issues with it on wicked rom, which I was using. I flashed wanamlite and installed the mod and it is working as-is. I am on m919, running wanamlite 1.5 and kt's latest kernel (9/17). Here is how I installed it:

I tried installing the custom busybox through the app, but the mod still wasn't working. So I think it is important to flash the busybox installer included in the op, then install the turbozram app and proceed from there. Hope this helps!

::edit::

Also, I just wanted to mention that the performance increase is immediately noticeable. I'll try to report back on battery life sometime soon. Thanks for this original mod!
[Galaxy S 4 Themes and Apps] rlorange:
Thanks for the feedback mate. Yeah Wicked ROM seems to be the culprit and you did everything right. The in-app custom busybox installer doesn't work for everyone either.

Glad you are enjoying the performance boost. I was thoroughly surprised when I first got it going myself :)

Hey

Just wanted to thank you for this great tweak. Working on latest 4.2.2 ktoonz with hyperdrive 10.2. It flys! While there is a large differences in speed the swap and ram won't stick on boot. I think this bug has already been referenced but I just thought I would share. Overall its still worth installing and running at each boot up.

Thanks so much.:good:

[Galaxy S 4 Themes and Apps] John_wba:
I have since moved across to faux kernel and your app says kernel not compatible, but it has zram ram built into the kernel, so it should work? I hope it can work with faux kernel as the battery and speed are far better than the KT kernel.
[Galaxy S 4 Themes and Apps] rlorange:
Does it have 4xzram built in?
