[LG Optimus 3D] DoSeLiNuX:
All know armv7 cortex A9 can work at ~2GHz ( if you like bbq lol ), on the p920 there is an ti omap 4430 @1GHz ( dual ), some kernels like PH can set the o3d at 1,4GHz.

ti omap 44xx are based on a9 cortex processors, in the namless rom the kernel set the cpu at 1,6GHz ( i've lose an 1,65GHz kernel on my pc lol ).

I think an ~1,8 - ~1,9 GHz kernel is possible ( maybe desactivate the second core under 1,6 GHz due to high consommation, temperature and stability)

Who think it's an good idea ? !

BBQ lalalalala...

KITKAT on PCs IS FUNNY XD
[LG G Pro 2] Kieran1981:
Is there a way to lock the rear buttons to stop the LG G Pro 2 from being accidentally turned on while in your pocket?
[G3 General] Heisenberg420:
I've seen a good amount of people complaining about lag, so i thought i'd share what i've done to get my g3 running smoothly.

* See below for kernel settings

First off I rooted my d850 with towelroot. Using titanium backup, I froze all at&t apps along with apps I don't use like kindle, uber, beats music. Also froze messages back & sync since it was always running, and I backup up my texts manually.

Everything I froze:

Now there's the whole art debate. I have noticed a big improvement in smoothness and battery life using art, but there's also compatibility issues with some apps, and xposed. When switching back to dalvik runtime you can definitely see some general UI stuttering, here's what can be done.

Kernel settings

I installed (and highly recommend) Kernel Toolkit and played around with a few settings. You'll have to install busybox too which worked fine. KEEP IN MIND we don't have a recovery to save our asses in case of bootloops so if you make any changes in trickster do so at your own risk, and when using set on boot, apply a long enough delay for you to fix any bootloops in the event that your phone doesn't like your settings.

That being said I would be surprised if anyone manages to find settings that causes reboots on the stock kernel, given that theres no voltage table to mess up, or any unique cpu governers.

Onto my settings:

I/O scheduler = cfq

Governor control (with interactive governor) -> hispeed_freq = 1267200

Here are some other changes you can make in governor control for better performance:

go_hispeed_load - change from 90 to 85

min_sample_time - change from 40000 to 50000

target_loads - change from 85 to 80 or 75 (75 = better performance)

NOTE: I have tested my settings for a few days and they seem to be stable. If you want even better performance (at the cost of some battery life) you can try some more changes DON'T use the set on boot option until you're sure they don't cause reboots! Once you deem them stable you should use set on boot with a 30 second delay. Without the set on boot option you'll have to manually reapply your settings after every bootup as kernel settings get set back to default on boot.

NOTE: I've found using the ondemand governor causes reboots.

With these settings i'm not missing art anymore. I've found that setting the scheduler to cfq takes care of most of the lag. Keep in mind that tweaking the kernel for better performance USUALLY comes at the cost of a little battery life. So you'll have to find a sweet spot that your happy with in terms of performance and battery life. Feel free to discuss and share your kernel settings :)
[G3 General] KiNG OMaR:
I'm probably the only one experiencing more lag with ART than not. With ART enabled my G3 was stuttering everywhere and I had to pull the battery ~3 times in 2 hours because the screen just wouldn't turn on.

It's silky smooth on dalvik though, lol :eek:
[G3 General] Heisenberg420:
Yeah sounds like compatibility issues with some of your apps.
[G3 General] Heisenberg420:
Tested ondemand governor, caused reboots.
[G3 General] bdt1978:
Surely a third party launcher will just sort all lag issues out?
[G3 General] Lookinen:
Why would it do that? Of course it helps with launcher lag but not with lag occuring in menus etc.

Oh and thanks to Heisenberg! Tried your settings and with art enabled everything works nice and smoothly. No more stuttering.
[G3 General] Japultra:
Please let us know how stable these settings end up being. Thanks!
[G3 General] Lennyuk:
I think people are getting confused over what is lag and what is not.

Lag is when the UI is delayed when it shouldn't be - this can be caused by a number of factors including wrong cpu clock speeds, overheating or lack of quality ram management (usually due to one or two poorly coded apps eating everything up!)

What most of you are experiencing on Dalvik is not lag, its just the way the JIT compiler works, apps on Dalvik will take a split second to open while it compiles what it needs, generally speaking this is not noticable, but we all know people on XDA always notice everything....

If you are experiencing lag then it is most likely caused by something other than Dalvik the ART build on this device is outdated doesn't offer anything (seriously!) over Dalvik, this in no way reflects what we will see on Android L.
[G3 General] stinkypoo:
My g3 suffers terribly from redraw it just should not be happening on something this powerful
[G3 General] Lookinen:
I had some noticable stuttering in many actions like in menus and scrolling. After changing to ART and enabling these tweaks they are gone. Placebo or not I'm happy with the results, no stutters or lag of whatever you want to call it :) I'm aware the ART included is nothing like ART on L, but to me it just helps that little bit.
[G3 General] Batfink33:
That's placebo.

ART only affects lag, that is the time between pressing on an icon and the app opening. ART pre compiles the bytecode needed to run an app beforehand thus eliminating the need to do it on the fly which dalvik does (it should also improve battery life as converting it to bytecode takes cpu cycles). It doesn't do anything for stutter or scrolling. By yeah the ART in 4.4.2 is old code as well and not optimized yet so there will be little improvement in lag also.
[G3 General] Lookinen:
So be it. It doesn't matter to me if its placebo or not. Feels nicer to use and that is what matters.
[G3 General] rushless:
Still not getting the ART love. For milli seconds of improvement you lose 25% of storage space. Not seeing the net positive at all, but a big a$$ net negative.
[G3 General] Batfink33:
You'll have no choice when "L" is released :)
[G3 General] ElBeaner:
I will miss Xposed if they can't get it to work right on ART
[G3 General] dondavis007:
I'll try your guide. Lag and redraw is not what I prefer in a new flagship. Art is more than placebo, it's notable better but I'll like to use Xposed.
[G3 General] rushless:
SadLy true :(
[G3 General] dondavis007:
Seems to do some difference. Even with art I had some lag in app drawer and it seems to be gone. Placebo or not, it's feels a bit more snappy in app drawer so that's another one to beat the dust ? So far I'll keep art on, I have loads of space and launcher and apps are notable snappier with it in. Its not like my M8 but it's a bit closer.
[G3 General] SpEaKeRb0xXx:
art

Sorry for a very noobish question, but can someone tell me what art is? I got my lg g3 last week and quiet playing a bit with it. I got the international version 3/32gb (LG-D855 V10a) and wanted to root it to somehow boost my battery life. Its fine and my battery can last a day with my normal usage and im very happy with it (waaaaaay much better than my ip5), but if i can squeeze more juice and make it last a day and a half or even more, im willing to root and take full pledge over my device.

I also experience having error that my device is heating up and won't be able to max out brightness, weird coz when it happen im actually doing nothing with my device, i just adjust brightness and it wont let me to max it out, so as of now im considering it as a bug and hoping that an update will fix it. It does warm up a bit but not the same as my toasty galaxy note 2 and galaxy s4 so i can live with it, but if i can remove the energy being waste and boost battery life by rooting it, ill forget OTA.

Anyway, back to my main concern,,, what is art? Hue hue
[G3 General] bdt1978:
Hey mate. Art is android run time. Do a quick google search on how to change it or one of the pro's on here can go into the finer details on the benefits of using it.
[G3 General] lossah:
Lol guy it was just an example lol. I can lol mention lots of other examples lol. You want me too lol?

Jisses, some people.
[G3 General] l5s5d6:
Setting row? What is that? Weird thing with usb debugging.

Wysłane z mojego Lg G3 d855 3/32 gb
[G3 General] Racer-1:
row is the standard setting on my G3. Do you mean cfq?
[G3 General] EEngineer:
Setting row as the scheduler. Yeah, disabling USB debugging surprised me, too.

I also just set the settings from the OP and the lag is almost, not quite, gone.

[G3 General] l5s5d6:
Row is standard for me too. What about governor? Interactive? Conservative or else?

Wysłane z mojego Lg G3 d855 3/32 gb
[G3 General] BrUhNiGGs:
Damn the OP has the max freq set to 1.2ghz? Is that not significantly slower as opposed to having it at 2.4ghz max?
[G3 General] MasK:
In the OP, it is mentioned that the cfq scheduler is selected.

So.. which is better? cfq or row scheduler?
[G3 General] BrUhNiGGs:
I saw a post earlier about seeder and tried it out and put it on aggressive mode. My G3 now feels very snappy overall. I forgot about entropy generators :p
[G3 General] drock212:
I also have my max frequency low. At 1.5 and scheduler of cfq with interactive governor. I believe my setting along with op are meant to reduce lag and also conserve battery. To save more battery I have my GPU at 389 and read ahead at 128. Even like this I dont see any lags.
[G3 General] ChrisM75:
I think some people have unrealistic expectations. All phones have lag, all phones. Some apps are over 100MB in size there will be lag when opening them because thats how long it takes to read the data off the internal storage.

Dont be fooled by the iPhones animations making you think its lag free. iOS starts an animation first, before doing anything else, then loads the app in the background, this makes you think its not lagging when really its just covering the lag with an animation, that sometimes is quite slow.
[G3 General] lossah:
ART. :) I dont have a problem with apps, its just the LG lag, even with Nova.
[G3 General] Racer-1:
The standard hispeed_freq is 960 mhz so i don't think that's the max frequency.
[G3 General] ChrisM75:
What lag? Ive never seen any phone that doesnt lag in some way. All phones lag with scrolling widgets, or in or out of the app draw to some degree. My G2 is very good because im using the Hyper governor, its faster than an N5, but its still got some sometimes.
[G3 General] Mistertac:
My phone seems to run really well compared to how others do. I use Nova as well. On Interactive Governor I can honestly say there's no lag. I can have all sorts of apps open, go into settings they pop right up, go into recents same deal.

When I'm on OnDemand Governor or Conservative is where I'll get the lag, but even then it's minimal.
[G3 General] lossah:
Home button lag and lg setting lag. But youre maybe right. Im very(!) fastidious when it comes to lag.

Edit: forgot the most annoying. Browser lag! Not sure if its chrome tho. But thats extremly laggy, especially when zooming and typing.
[G3 General] Heisenberg420:
No, that's the hispeed_freq under governor control. Min/max freqs are stock.
[G3 General] quim135:
Told that to nexus 5 owners...

It has lag on easy tasks as return to launcher or openning multitask...
[G3 General] Dr Forinor:
Is there any website etc that explicitly tells you which apps are not fully compatible with ART?
[G3 General] Schrotty35:
I use the settings from post 1 and nova launcher but this not help to make the g3 faster or smoother. In google plus, tapatalk or facebook i have scroll lags.

Gesendet von meinem LG-D855 mit Tapatalk
[G3 General] BrUhNiGGs:
Nova launcher isn't supposed to make your phone smoother and remove lag. But it is smoother than LG's stock launcher and that's why people recommend using it
[G3 General] tntgdh:
Really ? Something must be wrong with your device dude. I'm using nova here too with art and the thermal mods and couldn't be happier. The phone is everything I always wanted.
[G3 General] tsaojam:
I think that the lag that we sometimes see is a result of the system closing and freeing up RAM too quickly. For example, I've noticed on my G3 that opening the settings page takes at least 2 seconds to launch, everytime. Usually after you launch it once, the second launch is faster because it's in the RAM. What I also noticed is that I use Business Calendar Pro, and have the scrolling agenda widget running. On my other phones, I can scroll down and it will show "loading" briefly before the future dates load. Then when I scroll back up and down, the loading won't show anymore beacuse it's all there and there's no slow down.

However, on the G3, its will always show the "loading" and pause as I scroll to future dates even if I'm scrolling back and forth (hope that makes sense), so my guess is that the memory management is really aggressive in the G3 and it's constantly freeing up memory causing the "lag" which is just the redrawing. If that's the case, I remember that you can adjust the RAM reading and memory release settings and size if you're rooted. Can anyone with more technical expertise check on this and see if it's indeed a case of over-zealous memory releasing? I have 3GB of RAM in mine and it constantly has over 1.3 GB available so I certainly don't mind using more of the RAM to speed up the UI.
[G3 General] pYlOne75:
You should try to go to Dev Options in Settings/general menu and uncheck "Do not keep active app" (or something similar, my phone is not set in english). It should be on the bottom of the list, mine is the 3rd latest option

This is the opposite. He wants to keep apps longer running in the background.
[G3 General] mathsmart:
I use force gpu rendering and it seem to help a bit

From Lg G3 "the beast"
[G3 General] Batfink33:
Be careful, I fried my GPU by doing that.
[G3 General] EEngineer:
Can you be more specific? What happened?
[G3 General] l5s5d6:
And what it's the benefit of forcing it?

I experience more stutter playing games when forcing gpu is on.

Wysłane z mojego Lg G3 d855 3/32 gb
[G3 General] Heisenberg420:
Force GPU rendering should make little if any difference. All apps designed for ICS+ already use full GPU rendering by default. That option is there so you can force old apps (written before ICS) to GPU render since they weren't set that way by default.
[G3 General] Batfink33:
The phone got very hot and switched off. When I switched it back on the screen was flickering constantly. Signs of a damaged GPU. I had to get the phone replaced.
[G3 General] cruzargel:
Looks like disabling USB debugging made a difference to mine.
[G3 General] fix-this!:
Tried these tweaks and it still stutters on my g3. Sad compared to my g2.
[G3 General] exmatproton:
I have the G2 as well, running CM11, and that phone is way faster. But with ART enabled, the G3 is just a tad slower. I think it is mainly kernel/software based. And i am sure it will get faster in the next months.
[G3 General] StreetkillnHD:
Just waiting for unlock bootloader to install customs roms once there out im sure it will be a lot better

[G3 General] EMJI79:
Anybody could post a video of its g3 AFTER the tweaks, to let everyone see the result on UI and scrolling settings or web pages?
[G3 General] meyerweb:
Slightly off-topic, for which I apologize, but a bunch of you are talking about using Nova, which I use on my current Samsung device. I'm planning to pick up a G3 on Monday, and have one question regarding Nova on this phone.

Does knock-on work with Nova, or only the stock launcher? On my Sammy, I'm used to just hitting the home button to turn the screen on. I don't want to have to pick the phone up and turn it over every time I want to turn it on.

Many thanks.
[G3 General] Richieboy67:
Yes it works with nova just fine. :)
[G3 General] lossah:
Use a screen off app, go to Nova, gestures, set that app double tap = done. :P Exactly like LG launcher.

Or double tap notification bar anywhere on your screen (even with apps open etc) and it will go to sleep mode.

About lag. Its strange because in the morning when I use my phone it's pretty fast, at least quicker than after an hour, but I don't get why my phone should "throttle" even when it's not even warm.

So...why? :/ I have tried to turn off the thermal things in the hidden menu, both options, but nothing improved.

I don't get it.
[G3 General] Richieboy67:
I'm using nova paid version and the knock feature works. No third party app needed.
[G3 General] lossah:
Erhm no? I'm also using nova prime and removed screen off app and set "no app" for double tap. Not working. Ofc it's working to turn the screen ON but not OFF.
[G3 General] Richieboy67:
You have to hit the status bar for screen off.

---------- Post added at 11:38 AM ---------- Previous post was at 11:37 AM ----------

And screen off tap only works on the status bar even on stock g3 I believe.
[G3 General] lossah:
Nope. It's working anywhere on the screen just like stock. And yeah tapping on notification bar works anywhere, even with apps open etc.
[G3 General] Richieboy67:
I'm talking about stock. Your saying stock lets you tap on the screenanywhere too turn the screen off? That would seem problematic.

Plus, the question was about tap on working with nova and I verified it works with no apps needed.
[G3 General] lossah:
1. Using Nova launcher without a screen off app = knock off only works while tapping notification bar.

2. Using Nova with screen off app and set Nova to use double tap as gesture = works like stock launcher.

To turn the screen ON it works with whatever launcher you use.

You can tap on the notification bar even if it's not on "home desktop" (hope you understand. :p). As in even if you have apps open like tapatalk or browser.
[G3 General] Richieboy67:
The question was about tap on. Nothing is needed. It works as normal with nova.

##Question = Does the default launcher have tap off anywhere besides the status bar? I thought tap off was only on the status bar and this works with nova.
[G3 General] lossah:
Anywhere. That's why I'm discussing. :p it's only on status bar with nova without a screen off app, but anywhere with, just like stock.

Anywhere = "home desktop" and not on a app, obviously. :p
[G3 General] Richieboy67:
I see. My home screens are full so it made no sense to me.

Seems a little much though to have anotherr app running just too click off on a blank spot when the status bar is right there and works.

You are right though..tap off only works on the status bar with nova.
[G3 General] meyerweb:
Thanks. I know how to turn the screen OFF with gestures. I do it on my Samsung. But I asked about Tap ON, and no 3rd party app will turn the screen on when it's off, I'm don't think.
[G3 General] lossah:
Tap on works with any launcher.
[G3 General] Richieboy67:
You don't need an app. It works with Nova and probably any launcher.
[G3 General] meyerweb:
Another way to double - tap screen off

Regarding screen off tap, you might be interested in an app called Side Control:

http://xdaforums.com/showthread.php?t=2672134

https://play.google.com/store/apps/details?id=com.jamworks.sidecuts

While primarily billed as a sidebar type launcher it also supports a large number of gestures, which can be used from within any app, not just the launcher. And you can set multiple gesture areas, so a double tap at the left edge of the screen can do something different than a double tap on the right. I have a double tap on the right set to turn off the screen, without having to first return to the launcher.
[G3 General] partylikeaninjastar:
Tap on is a kernel feature that has nothing to do with launcher. Tap off on the status bar is system wide. Tap off anywhere else is dependant on the app.
[G3 General] eths83600:
Having some lags too.

Every time I go back to the desktop, I have a black wallpaper before mine loads.

If I open a game, let it load up, open on other and let it load up too, when I go back to the first one, instead of being loaded already, it loads up again.

But on my g2 both stay loaded even if many apps are open at the same time.

I'm rooted now and I'm not sure what's the best solution
[G3 General] xRamz:
For the apps closing. Try edit the oom values lower? And are you using stock launcher? I use Nova and keep it in memory, no redraws
[G3 General] meyerweb:
How does one do that?
[G3 General] xRamz:
I used this: https://play.google.com/store/apps/details?id=com.jrummy.apps.memory.manager&hl=en
[G3 General] EEngineer:
With Trickster MOD, I adjusted the Read Ahead Buffer Size from 512K to 2048K.

WOW!!! Phone is MUCH snapper, lag is almost completely gone!

Let me know if this works on your phone.
[G3 General] EMJI79:
How does it compete with a Nexus 5?
[G3 General] Curleyyy:
Has anyone found any good settings in trickster for a longer battery life? With the settings on the front page I've noticed it feels snappier but battery runs out a lot quicker.
[G3 General] lossah:
You sure it's because of trickster? I'm getting really good battery life with it (prob no difference).
[G3 General] EEngineer:
Same here, my battery life is great. You might want to try dimming your screen brightness.

You are completely right. This is really annoying.
[G3 General] Curleyyy:
With 10% brightness, WiFi off, GPS off, etc and including the settings from the first page, I dropped 60% in 2 hours with only using my LED as a torch. That doesn't really seem right. Unless an app was draining the battery without me knowing, I just feel like it dropped a lot quicker than it should have been.

Thank you!! I like to believe that there's actually a difference with this. Still feels snappy, while not dropping as fast in battery. Would you happy to know of any documentation that breaks down with information for what each setting does? I haven't been able to find any information so far apart from Schedulers.

Im sure this is old news and people have done this already, but my battery life is pretty damn good. Also, my G3 is lag free. I only did two things, went to developer options, disabled all 3 animations options, and then i installed "Seeder". I feel like there is almost NO lag or hiccups like i had before doing these two things. Also, i installed Nova Launcher as my default i feel like its blazing fast.
