Use this magical app to get rid of all lag in your Android device
Share:
LagFix (fstrim), as is the full name of this geeky piece of software, is based on the Fstrim Linux tool, which has the same purpose. Basically, when the user is trying to execute a task, the LagFix app attempts to inform the device's memory controller about the free storage blocks that can be used to write data on at the current moment. Alternatively, in the typical case (which is when you don't have LagFix installed), the memory controller has to "ask" the system about the free storage blocks, and the whole system stops responding for a while (usually less than a second) until the memory controller gets its "answer". So that's how the tool is supposed to work, but will it really work for you? Well, you'll really have to try it on your specific device in order to be sure, but as it seems most of the users who have tried it are very pleased with the results they have achieved.
If you are experiencing problems with the lag, and wish to give LagFix a try, you can download it here!

App requires root... You should mention that in the article.

Yeah they kinda missed that VERY important aspect of the app.

I'd switch it out for ridiculous. It doesn't seem fair in many ways.
39. KingKurogiii posted on 23 Jan 2013, 12:30 4
seem fair? this requires root access to work the way it's described to. it has nothing to do with favoring rooted users or anything of the such. still the lazy troll. :P

You can't root if the bootloader is locked.
44. roscuthiii posted on 23 Jan 2013, 18:36 0
You can root if the bootloader is locked, but you can't run a custom ROM.
47. anGel_pLayer posted on 23 Jan 2013, 21:32 3
You can root on locked bootloader, and you can install custom ROMs on locked bootloader as well. Though you can't install a custom kernel on a locked bootloader.
54. KingKurogiii posted on 24 Jan 2013, 13:30 0
you can run custom ROM's with a locked bootloader but they can't alter the kernel in any kind of way.
53. KingKurogiii posted on 24 Jan 2013, 13:29 0
yes you can. my Droid Razr MAXX HD is rooted and it also has a bootstrap recovery so i can dual boot into the unofficial CM10.1 beta should i chose to. i've rooted all of the Motorola devices i've owned to date and all of them have had locked bootloaders. quit spreading such misinformed information troll.

No big deal. If you're concerned enough about your android phone. You should atleast have the knowledge of rooting it. I wanted to throw my GS2 and buy and iphone but cm10 changed my opinion completely. However, I agree with you.

Why us there lag in the first place? Project Butter was supposed to end lag in android.
7. SuperAndroidEvo posted on 23 Jan 2013, 07:35 11
Ohh taco50, how much do we miss you. Those were the good old days. lol

I opened this account just to tell Taco to shut up.
40. tedkord posted on 23 Jan 2013, 12:41 4
Thats true. Taco was slightly crazier, but much more interesting and entertaining.

You are clearly the most weak person here in PhoneArena.com. There are millions & millions of phones that were sold BEFORE Android 4.1 Jelly Bean was introduced.
This app is clearly intended for those millions & millions of Android users who are running anything below Android 4.1 Jelly Bean. Everyone who has Android 4.1 Jelly Bean knows Project Butter is wonderful.
If you really have no clue then please spare us your ridiculous comments. You really hurt your cause when you open your petty little mouth. Educate yourself before you talk. lol
6. Cyan3boN posted on 23 Jan 2013, 07:34 15
Its for low to mid range phones which may never see the light of jelly bean.

I take it you didnt even read the article....I hope you didnt. If you did.....wow....

why does the iphone 5 freeze and lag??
you are one pathetic loser!
15. SuperNexus posted on 23 Jan 2013, 08:43 1
look like you didn't read the article....... it says modestly-spec'd handsets.
now tell me which modestly-spec'd handsets has now Android 4.1.
so what Project Butter is doing.
If you don't know anything then keep your mouth shut.

With exception of the sgs3 international and the new nexus this is a must for everything else.
30. tedkord posted on 23 Jan 2013, 10:23 3
Nah, my Thunderbolt with Gingerbread was completely smooth. Zero lag. I even posted a video on youtube to challenge an iFan to identify the lag. Her never replied, of course.
45. jroc74 posted on 23 Jan 2013, 19:28 0
Funny...I didnt need it for my Droid X after the GB update. I didnt need it for my RAZR and Maxx HD.
I didnt need it for the G Nex or Rezound either.
Alot of what ppl complain about with Android is home screen scrolling. Changed the launcher on my Droid X1 before the GB update...and all was well. Lock screen too. Its a shame sometimes you have to do that for some phones.....but home screen scrolling and the lock screen does not equal the entire user experience.
Also...Moto has been notoriously bad with a choppy gallery app. They finally got it better...something Samsung and HTC had right almost from day one.
24. rusticguy posted on 23 Jan 2013, 09:38 0
Because iphone/pad requires smooching the screen for every little change which is biggest lag that one could ever experience ...
28. tedkord posted on 23 Jan 2013, 09:58 1
And, as the article stated, the newest mid to high end devices deliver perfectly fluid user experiences.
I know reading comprehension isn't your strong suit, but this was plain to read.
35. BREvenson posted on 23 Jan 2013, 11:10 1
You know, there was an iFan just like you on Droid Life who said something very similar when they wrote an article about this. Granted, he used more than one or two sentences and had what seemed to be a deeper knowledge of these things...but I'd still say he could pass as your exact double...or a cohort of yours.
Either way, you missed the other points of the article, such as "modestly-spec'd handsets". Phones like the Galaxy SIII, Optimus G and the Droid DNA won't be needing this app. I would say, though, that there should be something to fix the lag in your brain; seems like you've been needing some help with that for a long time...

Here's the man page for fstrim:http://manpages.ubuntu.com/man
pages/oneiric/en/man8/fstrim.8 .html
Basically what it tries to do is reduce the number of blocks that are unnecessarily occupied on the storage device. therefore when your phone tries to write something to storage, it doesn't have to waste time rearranging blocks to find a chunk of open storage space. This is basically useless on Android 4.0+

Too bad i have android 2.1. It seems just about everything says 2.2 or up -.-

I am running 4.2.1 already, let's see if LagFix makes my already awesome experience even better~

Lag Fix?? WTH?? Thought Android phones didn't LAG!!!!
36. ChafedBanana posted on 23 Jan 2013, 11:29 0
Well, then maybe you should root. I can't even imagine not having root access.
38. Jyakotu posted on 23 Jan 2013, 12:05 0
So glad to not experience (as much) lag anymore. The Samsung Intercept was a horrible experience.
42. Twisted247 posted on 23 Jan 2013, 15:26 1
Chances are if someone has rooted their phone they have fixed their lag issues with a custom ROM or other tools the dev's in the community provide... If it was a tool that could be utilized by the regular community which isn't rooted then it would make more headway.
Other reason being most people who root are "in touch" so to speak with their phone and it's hardware. So they probably wouldn't purchase an outdated under spec'd device that is lagging cause their wouldn't be hardly any support for the device.
None the less ....... cool
46. jroc74 posted on 23 Jan 2013, 19:31 0
You make some good points. Just by spending time in a root and ROM section....any first time rooters will see threads and see ppl post about making things faster, smoother, etc.

Wooow this app is truly magical, i own karbonn a9 (gb 2.3.6, 1ghz single core, 512mb ram) it used to lag as hell, yesterday I rooted my device (only for this app) and installed this app now my phone seem to have project butter inside it, it just doesn't lag any more. App worth the risk of rooting.
49. will0286 posted on 24 Jan 2013, 00:37 0
I would like to first apologize if this was already stated I read most of the first page and it was mostly bs.
For starters I completely agree with kingkurogiii and superandroidevo. I'm all for rooting and enjoy learning the ins and outs of my phones. If you really want the app that bad don't be mad that you have to work for something you want just put in a little effort and try.
That being said even though I agree with certain comments I still think your all missing the point in leaving a one. People want to read the comments to get an idea of what kind of results others got and decide if they want to try it. There are only a few comments that were helpful. one said you have to be rooted, and a couple said works great. Everyone else is just arguing.
I'm tempted to try it on my dna but I don't get any lag yet, but have tried it on some phones I was working on (Optimus S, Evo, Fascinate) and more to come. It does not make them go super speed but it is a noticable difference. I recommend for anyone having speed issues
And I'm sorry but I do have to comment on one more thing. lock bootloaders can't root, flash custom roms, and kernels........HA. htc really made it a pain compared to when the evo first came out, but I am not capable of running stock and will always find a way. Thanks for reading hope I helped a little

I decided texperience whether ce this will be useful or not?, but this got me very curious and as I have already rooted my nexus 7 32g 3G I decided to make a run for it and installed this app.
What I wanted to see was whether there would be noticeable improvement in the games I have noticed some frame rate drops more or less frequently appearing while playing.
I tested NFS: Most wanted
Anomaly Korea
Ikaruga
Zen pinball
Nova 3
In my own experience I noticed /experienced a great improvement in overall performance. Games like NFS had no lag or juttering, at all.
I haven't yet pushed my nexus to the limits when opening lot of apps to the point there would be lack of central memory and would it perform better under those conditions.
But to give my first impressions thus far, the this is a very good addition for tweaking up the nexus 7 performance in more graphically demanding games.
Thanks for the creator of this app
