How to make your LG Optimus 2x run like a Rocket! (Requires Root)

You don’t need to change your ROM to get the best from your 2x, just a rooted stock ROM and a couple of apps that will change things dramatically. One thing I’ve noticed on the 2x is its memory management is too lenient and gets consumed quickly by background tasks etc. In no time I was down to 40-30Mb free memory and then my phone would run like a dog resulting in a reboot as the only solution.
Installing task and app killers are not the way, as they’ll only give you a short respite before the apps and background tasks you killed relaunch.
However, there is a solution.
1)Root your phone using SuperOneClick (piece of cake, instruction already on this forum)
2)Install “AutoKiller Memory Optimizer” by AndRS Studio free from the market
Optional
3) Install “Watchdog Task Manager” by Zolmut LLC (There’s a free or Paid version) I paid!
4) Install “Root App Remover” by Best of Best Android app
AutoKiller is not a task killer/manager it reconfigures Androids inbuilt memory manager to kill or suppress memory usage by applications and tasks. I now always have about 140-170MB free RAM at all times regardless of what I’m doing (but I do close my apps with the back button rather than click home)
AutoKiller Memory Optimizer Settings
I’ve used the ‘Extreme’ settings to ensure I have around 150MB free, and this makes a huge difference in everything I do with the phone.
----------Optional things you may want to consider-----------
Watchdog
Yeah, I know this is a task killer but Watchdog is different from other task mangers as it monitors CPU usage rather than free RAM, 3D Gallery for example is a CPU hog on my 2X, so I configured it to be killed if it consumes more than 30% CPU whilst running in the background, you’d be surprised what saps your battery!
Root App Remover
Uninstall the tosh supplied on the ROM, I removed the following, AndroidBackup (I use Titanium Backup), CarHome, F-Secure_Mobile_Security, SNS (If you’re not using the built in Facebook and Twitter app).
I also use LauncherPro with Beautiful Widgets to give my phone an almost HTC Sense look and feel and uninstalled LG Home using Root App Remover afterwards.
Hope it makes a difference for you, it did for me, vote if you like

What do you think having 140-170MB RAM free at all times actually does?
Guess what? Nothing.

I disagree, my phone runs way better now, maybe due to the fact that in part it’s killing more background tasks and enforcing better garbage collection. I want a phone that when I go to it, it responds immediately, I don’t want my phone to chug along whilst a new app is launched and android then decides to kill lower priority background tasks resulting in a choppy experience. These are my findings, and I wanted to share them. As a result using this particular application I now have a phone I can enjoy, rather than being frustrated by pausing, choppiness etc.
I would welcome your reasoning to why my post is useless, or explain why my phone is now running so well? Are you saying I’m suffering a placebo effect? Remember, this app is not a task killer, it reconfigures Androids internal memory management, see here:

I tried the app too and i can say that it works, I also did some of the advanced tweaks.
phone seems more responsive now.

Yes, me too. It's more responsive now. Also when I open app manager, the app list is a lot faster.I know it's more related to file read/write but still it's nice to finally able to browse with less waiting time.

thx
good one and simple, thx

cann someone please post some benchmarks?

Here are some screenshots, tested with AnTuTu Benchmark
The first one is v10c stock, some apps like f-secure, carapp etc frozen, second one is with using autokiller memory with preset extreme, third one is to compare, this was while using cm7.1 rc
now we'll see if autokiller works stable ^^
edit: realized that with cm7 something seemed to be wrong with the sd-card, so don't forget to compare the single-scores

I'm sure Rusty knows what he is talking about. Thing is, this talk about "the more free ram the better" has been repeated so many times, and at the end of the day, it seems to be more about user preference.
The default LG ROM seems to allow tasks to run in the background until it reaches around 50MB free RAM, then it starts to close tasks one by one. For multi-taskers like me, this is fine, I love how I can switch between facebook, tweetdeck, miren browser, google+, gmail, and messaging without seeing the apps reload.
For some, they'd want to open a task, close it, and move on to another without looking back. I guess that is where the 100MB of RAM is good for.
If you guys will be looking at benchmarks, I can guarantee that you will have higher scores with RAM optimizers. As benchmarks do not test multitasking, they simply check the performance of your phone at that point in time. (Which is also why some modders pump up their CPU freq to insane values before doing their bench then posting it.)
I have nothing against AKMO, and I find it very effective for Froyo builds. But I would recommend that each user try it out themselves. It's not a "1 fix for all" thing.

I'll just say this once: Free RAM is wasted RAM. If you feel´your phone is slow try adding some swap space

Does O2X already support swap space in EXT? (Or are your referring to VM heap?)

Doesn't play well with Fr19 at all (2 reboots in 2 minutes). Maybe I touched some settings that I shouldn't though.

Yeah, FR19 is one of the more stable ROMs out there. Try full wipe then reflash maybe.

Stock vs custom - multitasking

So, i've tried many different roms out there on my SGS. Never got any major issue with flashing or setting them up. Supposedly a custom rom has something improved but there was one think i kept thinking they all fail and i was wondering if anyone else feels the same.
I see random posts all the time telling how great multitasking in android is. But all these roms i keep using try their very best to close just about everything i have running. As far as i can tell, a few seconds after i switch to anything else, my first app gets closed. For example, everytime i'd leave browsing to manage what im listening to or sort out files on some file manager i'd find i needed to open my browser again instead of being there opened and waiting for me to return.
After searching for a while, the best explanation i could find out is to prevent battery drain from opened apps and to keep things smooth by having free ram, which kind of makes sense. Goes against what i read in a paper from google about android multitasking but fair enough.
Except the other day i happened to returned to a froyo stock rom (JS8 with darkcore 1.4) on my SGS and found out this does not happen. Apps stay open for the most part, except when i run something really heavy (like a game). And i dont really notice any performance decrease or extra battery drain from my usual usage.
Granted, i could be just told something along the lines "well dude, just use whatever works for you" and i totally plan on doing so, hence me experimenting, but thats not really my point. What i'm going for is, are custom roms being overzealous? because this really spoils any attempt at multitasking...
Again, this is not a rant of any sort, i was just wondering what are other people's thoughts about it

I'm suffering same problem
i want to have the browser and messenger at the same time
it close one after swetching to the other
i have 80mb free ram

I had the same problems, although lack of multitasking appeared on my stock rom, not a custom... sgs couldn't handle faceboom messager, viber, and a browser at the same time, everytime I switch from my browser to something else - it gets killed, which is frustrating
at the same time I saw how nexus s work, and how much free memory it has, compared to mine, the difference was huge!
I tried cyanogen at first, which was very close to stock nexus s, but it doesn't work good with sgs's camera and crashes once in a while
so eventually I installed JVT with voodoo and uninstalled different samsung stock apps, which gave me about 50mb of additional RAM compared to stock, and there doesn't seem to be any aggressive memory cleaners working, so I can now finally switch between all the apps I need

If you want the best roms for multitasking, go for the final builds of Froyo 2.2.1. They have plenty of free ram and are very smooth. I'd recommend Froyo ZSJPK. You can download it from XDA.

I think it depends on the ram settings in your ROM. The way android works is there are a bunch of system settings on how much ram to keep clear, and if it drops beneath certain values they start killing apps.
It's highly possible these values were tweaked in the custom roms, to improve the perceived smoothness and so on, but at the same time reducing multitasking. There's a trade off between performance and multitasking (guess why apple was so reluctant to add multitasking?)
I'm not really an expert on it, but I'm sure some quick searches around will find out where those values are and how to change them.. some rom/app probably even allows you to tweak them to your liking.

All Gingerbread roms do the same, closing apps after moving away from this, don't know why, but froyo didn't do this and ginger does.

I used to be like TS, clearing RAM because it might let the phone run smoother. After getting more exposed to Android, I realised that it could be logical to keep your apps in RAM instead of doing a cold boot again, meaning to close an app, open, close and open again, making it taxing on the phone.
So I tried to use up as much RAM as possible and it works just fine, it feels good. I believe the problem you have stated is that in your ROM, the task manager has instructions to clear the RAM once it hits a certain threshold. When it does, it starts to clear apps in different category, starting from what is known as empty apps, which are generally just apps you use and are not important to the android OS or rather independent from the OS.
In the new Samsung ROM, the threshold is set to 40MB, and it is working great for me. You can go to the android market and download "Galaxy Tuner" to set the threshold to a value you feel comfortable with. To multitask better, set the threshold as low as possible.

How's your experience with app background closing on ICS?

Hi. I tried a few of ICS roms available for i9000 out there, and all of them are pretty fast, much better than I expected. The only issue I have with any ICS rom I've recently tried is that they close apps in background quite often. For example, I might open my Opera Mobile, switch to SMS app, send a message, and then when I return Opera has to start over and load all the pages again. Does it happen to You as well? As a comparison, I tested it with a 2.3.4 MIUI rom I had as a Nandroid backup, and it's much better - most apps stay open in background for a longer time.
Is it possible that ICS has that bigger of a memory footprint over Gingerbread? What are your opinions on that? Experienced similar issues? Any workarounds?

Try using less widgets. Don't use apps like Facebook. Check push notification services of some apps.

Also, i seem to remember that Opera Mobile tends to "forget" loaded pages very quickly, if you don't come back to the app quite fast...
You can also try and check under settings > developer options > see if you have checked "don't keep activities" and under "background process limit" choose "standard limit"

Since I'm only getting advice, I take it I'm the only one having this problem? Strange. The only widget I have on my desktop is the stock ICS analog clock widget, and there is no such thing as "Developer options" in my Opera Mobile.
Right now I'm using AOKP rom b27, there is an option called "Free memory - Amount of RAM the minfree taskkiller will keep". I tried to change it to max possible - 100MB, didn't change anything.
Is you are using ICS roms, you never had such issues? Which roms do you use?
PS Could a different kernel make it better?

Opera uses alot of memory and the phones memory is very limited. Doesn't matter the ROM it will often get closed when you leave it to do other things.
BTW increasing the memory the OS keeps free makes it worse, how do you think it frees memory? By closing things. You actually want to decrease the memory it keeps free to try and help with this. The downside is that the phone will probably lag more and I have found it doesn't help much.

I'll try to use the stock browser. As to that task manager setting:
The description says:"Amount of RAM the taskkiller will keep", so I have no idea if it means keeping some RAM available at all times or is it the amount of RAM that can't be cleared.

It is never the amount of RAM that can not be cleared it is the amount of RAM to keep free. ie if you set 64MB Ram to be kept free Taskkiller will keep that amount of memory free by killing the oldest non active task/process

Samsung Galaxy S mysterious ram usage cm10.1

Hey there, this problem might have been discussed before but I wasn't able to find it, so the problem is with ram usasage, I once went to the apps in settings and on the running apps I always see 250mb+ ram used by something, then I killed all the apps, but that just made a dliference of 50mb ram, It's real anoying because when I want to switch between apps it's slow and when I turn a browser back on after using aother app the page realoads which I guess wpuldn't happen with 300 mb ram, does anyone know the reason for this, I am currently running cm10.1.
Thanks!

Free RAM is useless. It just sits there sucking up power and being available in case you need it. It's pretty much a waste to have 300 MB of RAM and then only use 100 MB. Instead you should try to keep your RAM full at all times with the things you are likely to need in the near future. For example, if your phone is currently only using 20% of your RAM but already caches the browser in case you'll use it soon it will be faster to load the browser. If you decide to use the music player on the other hand the cached browser can be overwritten with the music player without requiring any additional time, so no harm is done.
Modern systems don't have "free" and "in use" RAM, they have "free" (wasted space), "in use" and "cached". You shouldn't look at the amount of free RAM but rather the amount of actually used RAM is a better indicator.
The reason you only gain 50 MB when you kill all apps is because only 50 MB will be actually in use by apps and all remaining unused space is used for caching things. If your phone is slow, this is not the cause of it. You may just have a slow phone or the ROM might be slow for some (other) reason.

yeah only 50mb is used to keep the apps running, but it probably takes up a whole lot more when using the apps, and this is a problem for me that it is slow to change between apps, and when I do change between the for example if I wanna text some one back while using a browser, once i turn the browser back on it restarts the page, and that didn't happen in my zte blade, unless I had some more apps running.
I wanna know what is using those 250+mb of ram!

see exchange service,any svn services n keep track of system usage. normally 100mb+ will be taken for ui, framework...etc.
but. eventhough u keep track of it,then slaughter it, it will come back to life n running, so i wouldnt recommend slaughtering system usage.
switching between app normally slow for full or stock rom. try find some debloated rom. it will be suitable for u if u wanna more free ram rather than liquidity.

I also observed some sluggishness after some time of usage. Sometimes the phone got totally unresponsive, not catching any push events (from buttons or screen), so that I couldn't even wake it after the screen timeout. I had to wait even few minutes before it was alive again.
Google Chrome was the most ram-eating app as far as I know.
Sometimes the best method is just restart your phone from time to time or even make a wipe - this is normal for all low-end android phones as they get sluggish after some time.
Long story short: I ended up buying a new phone with 2gb of RAM

I have the same issue
I'm using CM10.1 RC5, kernel 3.0.76-gc0a8d45 [email protected] #1
I have same symptoms pawci0 and ltkipras mentioned.
But I don't want to buy a new phone...
The lack of memory is noticeable when I run Waze or maps . It just opens for a couple of minutes and closes by itself or rather hangs the entire device.
What should I do? Go for the CM10.1 stable, try a different ROM (i.e. Slim). Change kernels?

nope, waze doesnt use that much ram, try to fix permission first n clear cache in recovery
n try to use other kernel, mine ok with multitask, rather heavy with online games n hearing mp3 n receiving whatsapp, line n we chat at da same time
n try greenify app to control app thats always running.

Just try a other rom or kernel you would be amazed how lets say a change of kernel can speed things up. The point is everyone uses their phone differently different apps and things so you need to find the rom that suits you mostly.

[Q] Trouble with RAM management?

I got my Xperia Z1 about a month ago, and I've noticed some issues with RAM management (or possibly under-optimized third-party apps). Although I haven't had much luck in replicating the problem, I noticed it happen a few times after a Firefox internet session, or after playing a graphically intensive game like Dead Trigger 2. The app would either close by itself (not crash, as in, there were no error messages), or, after I'd close it, I'd notice my launcher (Nova Launcher Prime) go into a restart loop. A quick glance at the running apps section in settings shows 50-100 MB of free ram, and all "constantly running" apps (launcher, viber, zooper widget, k9-mail, swiftkey, tasker, etc.) stuck, for want of a better phrase, in a restarting loop (due to lack of ram I guess).
I tried running Fast Reboot (a task killer) to see if I could regain stability of the system, but it kills only a few system tasks, freeing up to a measly 50 MB of RAM, which makes me wonder (in aggravation) just where the RAM is being used. The only way the running apps would stop closing and restarting (and I need the launcher stable) is to reboot. I'm not sure if the system would stabilize after x minutes, as I only waited for a minute or two before rebooting so that I could open another app/game.
I'm not trying to start yet another debate on necessity of used RAM on Android and efficiency/futility of task managers/killers, but what I described above really seems like poor RAM management to me. I've had a few android devices in the past, and experienced various problems /errors, but never something like this.
Has anybody had a similar issue, or have any tips?
My Xperia Z1 C6903 is currently running on rooted stock 14.2.A.0.290

Although i dont get force closes, but ive noticed most of the ram is taken by the phone itself, right now for me it says i have 1.1gb in use, when i close everything i have just a slight (barely even noticeable) increase in free ram, when i click on cached processes and close all one by one ive seen it increases the ram use instead of decreasing it?
But, do you use apps like setcpu? You can keep it on performance and keep the min slider to the lowest and the max slider to max, it runs stable and gives you performance when you need it, and no performance when you dont need it.
If all fails, try deleting system apps that you barely even use or need... Becareful what you delete tho!

Thanks for the reply. No, I've used apps like that in the past, but haven't installed anything similar on the Z1, because I noticed in BetterBatteryStats that the CPU speed goes down often when the screen is off, and up when, I suppose, it's required, such as in intensive games...

What apps do you use? For example facebook, YouTube, browser etc
Ive checked again on my cached apps and to my surprise, AOSP browser takes up 208mb!
Facebook takes up 48mb, and youtube takes up 22mb.
It just depends on the apps you have installed, some use the ram even while the phone is asleep.
Ive stopped those and a huge difference was made on freeing up my ram!
What i dont get is tho why sony advertises 2.2ghz quadcore if the phone itself takes most of it?
Just delete the apps you dont need from "all apps".
