If someone could make similar test for Nexus 5 vs LG G2 and iPhone 5S vs LG G2? It would VERY much help to sort things up in those "OhMG, this G2 is soooo slow and laggging" issues
[G2 Q&A, Help & Troubleshooting] MohamedOMostafa:
I was about to buy the G2 in a couple of days but after seeing this thread I'm having second thoughts, so all I wana know is do other smartphones of the same range share the same stutters/lag ( Nexus 5, xperia z1, note 3 n9005 ) ? and after rooting and using a ROM close to the stock android the lag still exists ?
[G2 Q&A, Help & Troubleshooting] sojrner:
Agreed, turning off smart screen + trimming down to three screens (mentioned by jayochs long ago) seems to have mitigated the issue for me...

As pointed out by many, it appears localized to the G2, stock launcher. (For the specific redraw lag when waking up or returning to home from app) doing the above makes things better. Skill other lag issues are not what the OP was looking at AFAIK.

[G2 Q&A, Help & Troubleshooting] Billy Madison:
So, is there progress? Does stock ROM still have lags or now lag-free?
[G2 Q&A, Help & Troubleshooting] mannequin:
stock rom never had any "lags".
[G2 Q&A, Help & Troubleshooting] sojrner:
Interesting development...

The "lag" they're talking about is really a re-draw of the home page at certain times. The phone itself is not lagging.

In other news:

So I was looking through the Google play summer sale last night and got suckered into buying the "3D Tornado" live wallpaper for $.99. I knew the moment I opened it up that it was not as cool as the reviews led me to believe, but I figured meh, it's only a buck.

Today however I've noticed something. Since running this live wallpaper, every time I wake the phone up or exit an app, I have zero launcher re-draw issues. I mean literally none... zip, zilch, nadda.

Even after the things listed in other posts about trimming down home page counts and removing widgets, I was still seeing a re-draw right after unlocking the phone on wake up or after exiting an app. Some times it was much worse than others, but it was always there. Let me clarify the actual problem I've seen though so there is no confusion: after unlocking, I can try to swipe to another page and either the page will start to move and halt midway, or it will not move at all. After about 5 seconds (sometimes less) it will redraw the page slowly and then all is back to snappy and normal. During the halt of the home page though, I can access the notifications bar just fine and pull open the app drawer, the home page icons are just unusable for a few seconds.

Apparently with this live wallpaper though, all that is gone and the phone is operating normally.

Of course, this is hardly a definitive test and I will continue monitoring this for a day or so (including battery life) and then test with other live wallpapers to narrow things down, but I thought I'd post to see if others can corroborate these results.

For info, I am running stock-based malladus, but had the same issue on un-rooted rom as well.

Rock on.
[G2 Q&A, Help & Troubleshooting] sojrner:
Update after running live wallpaper for a day:

Batt life is affected, though I can still get 4 hours screen on and moderate use of phone and apps with enough to spare after a full day. (18 hrs uptime with no charge) usually I get better, but it's not the end of the world.

Occasionally a re-draw is briefly seen after watching a long video, (I.e. Netflix) but waking or returning from other apps up no longer has this issue.

I wonder if those who say they never had redraw issues were all running live wallpaper...

- mobilized on malladus
[G2 Q&A, Help & Troubleshooting] sojrner:
I have no idea if anyone cares about this anymore, but last update:

I found that like everything else on the stock launcher, the live wallpaper works great for a while, then gradually has the same problem. The redraw issue showed up after a few days again. It's better than non-live, but it's there. :(

So in the end, looks like the stock launcher will always have this issue to one degree or another... sigh...

So, the heavens opened up and gave unto us ART. So spake honorable knight of the round, xdadebb... ;)

Go get his v2.0 Rom, set it to ART in dev options and enjoy the lack of launcher redraw and lag, no matter how many screens or widgets. Been on it for a couple weeks with no issue.

You lose xposed support, but I can live with that to have this phone operate so buttery. :)

Had same lag problem with avast and nova. Removing avast fixed problem

Turns out that was not the problem, but uninstalling nova and re-installing it worked.
[G2 Q&A, Help & Troubleshooting] HyPeXeLeD:
I've noticed some lag shutters and re-drawing on JB when phone was just new and i started loading it.

Now i'm on 4.4.2 Kitkat + CloudyG3 ROM + Dorimanx kernel.

I had some micro shutters randomly on ClodyG3 default kernel, but nothing really noticeable, just an extremly exigent guy like me would notice it.

But ever since i went into dormanix kernel my phone literally looks like switching from a Tuned street car into a F1. I did notice some lower battery life compared to default kernel, but i cant remember of any shutter or re-drawing at all on this kernel, still able to always reach the end of the day. Its about 11:50PM, my phone is at 12%, i unplugged it at 6AM. I even played GTA:SA for 45 min, wich really drains the battery and got 2h 45min screen.

So if you're not extremly exigent with battery life, i'd strongly reccomend testing Dorimanx.

Hi Friends.

I am on Verizon stock and facing this issue since day one. Reducing the screens and removing the widgets didn't dhow any improvement at all. Accidentally, I found some steps to fix this. Not sure whether it's a permanent fix or not. Right now it's working for me with no any lag anywhere. Give it a try.

1. Go to developer options check 'Don't keep activities' set Background process limit to ' No Background process'.

2. Try to open a few applications and try switching to home for a couple of times. It will lag heavily.

3. Now go back to developer options and rollback the changes done in step 1.

4. Repeat step 2 for a couple of minutes.

After doing these steps after every restart, it is giving me no lag. I think there is some activity which is killing the performance and doing the above steps restarts that activity and allows it to work correct;y.

I was also suffering from the same issue till today.

And just now i figured it out that it was getting caused because i had sliding wallpaper. When i changed it to portrait it stopped lagging on pressing home button

Can anyone else please confirm this?
[G2 Q&A, Help & Troubleshooting] michi491:
Trying it, i'll let you know

edit : still have redraws with fix wallpapers
[G2 Q&A, Help & Troubleshooting] sojrner:
Ya, I pretty much concluded that the LG launcher for the G2 just does not stay in memory (persistent) and so suffers from redraws when going back to it from pretty much any app. It largely is based on how system intensive the app is you're in coupled with how long you're in it. (i.e. the more intensive, the less time it takes for the launcher to be pushed out of memory) The more apps you have installed, the more widgets you have taking up memory, the easier it is to trigger the redraw.

When using nova and their "Aggressive Desktop" setting, I do not see the issue, regardless of rom. I noticed nothing at the start without that setting, but I keep it on and have not noticed a change. I've been on the same rom now for about 4 months, the last three have been running nova with no redraw issues. All attempts with stock launcher, on all roms tried, I've always run into the redraw at some point after flashing...
[G2 Q&A, Help & Troubleshooting] airjordan223:
So I've been having unbearable lag on my G2. Non-rooted running Nova prime.

3 home screens, 3 widgets total, not a whole lot going on.

I tried this method out above and it didnt really help. What did start to happen though, is whenever I push the home button, the recent apps tab would come up. Started to get really annoying so I factory reset my phone and it's still happening.

I went to dev options to show where my taps are, and basically if I tap anywhere right of the circle, its reading some ghost tap and bringing up the recent apps as well. Anyone know what the heck is going on?

I will also note that sometimes if I hit the back button, it will stay lit for a while. I can go ahead and do other things on the phone, but the back button stays lit as if its being pressed. This is much less frequent than the recent apps ghost taps.

You can see where my press is, and the recent apps button is highlighting as well.
[G2 Q&A, Help & Troubleshooting] sojrner:
Pretty sure that unless you can freeze the stock launcher or get to an AOSP version, which both require root, you're honked on the lag. Dunno about your screen press issue though.
[G2 Q&A, Help & Troubleshooting] :
wait how did you install apps, was that throught backups?

Try reinstalling fresh after factory reset one by one. This to eliminate data issues that could slow things down.

Another idea is check settings of those apps. If on launch they first need to make a data connection, that could also slow things down drastically.

So if all above doesnt fix it, your not root or running custom stuff then its probably a device issue. Only then...

Also define lagg, some things just wont be instant. It could be on the other hand an app issue

Is THIS a lag? Title suppose that it's a lag

[YOUTUBE]kHHo85lj0ak[/YOUTUBE]

I think scrolling is pretty fine and fluid
[G2 Q&A, Help & Troubleshooting] Div033:
This is the kind of lag I'm interested in... Or more accurately, frames per second throughout the UI. Thanks for the account.

In my opinion a device feels more pleasant to use when it has a higher frame rate during UI navigation, so I gravitate towards devices that excel in this area. Apple understood this basic principle from when they initially conceived the modern day smartphone. It's mind boggling and disappointing that huge companies like Samsung or LG don't prioritize high performance when they create their software... The real tragedy is that most people don't seem to care, thus Sammy and LG have no reason to change.

I'm getting sick of my S3 (despite its lovely AOSP ROMs) and want something better. I really want to love the G2. It has a remarkably small bezel and magnificent screen but the TouchWiz-like skin, fully equipped with stutters and all, has me attending church every Sunday PRAYING for a Nexus 5 on Verizon.

The Google for project Butter and Qualcomm are to blame for lags in Android UI.

Then again, if Optimus UI indeed has many noticable lags the source of 4.2.2 ROM should be on ftp somewhere and everybody should has access to source to point LG to sources of lags

The most people really don't see and notice any lags especially in Optimus UI. It need very picky and hardcore man to notice them

I have issues with the touchscreen. About two times a day it will become buggy and just start jumping around on me. This makes it impossible to type using the swype method. I am running all stock (even keyboard) to troubleshoot the issue. Once I put the phone to sleep and unlock again the issue goes away. I'll try to capture video next time it does it.
[G2 Q&A, Help & Troubleshooting] jayochs:
no, that's not lag at all. there's no stuttering.
[G2 Q&A, Help & Troubleshooting] Div033:
Yeah I realize I'm probably the minority on this. I have an extremely keen eye when it comes to performance thanks to my background in game and graphic design.

"It's a tragedy to me" I should have said. The way I phrased it was a little condescending. Sorry about that.

[G2 Q&A, Help & Troubleshooting] Billy Madison:
Yeah, that's what I'm talking about, some people see lags in places where others just see fluid responsive UI. And sometimes animation of windows moving considered as a lag. Very different needs and demands of different people. For some 15 fps in animation is not an issue at all, and for some anything below 60fps is stuttering, lagging, and pissing them off.

I've had a few g2s already and the 3rd one lagged. That one is now on its way back and a new (4th) is on its way. Will see what happens when it gets here. The first 2 had no lag at all.

Before anybody asks:

First one had a camera problem - when taking a pic in direct sunlight, the screen would shut off. Resets wouldn't fix it or anything..

Second one had muffled speaker voice and the grill over the speaker was dented from factory.

Third one lagged, had dirt under the right side of the screen and the power button was recessed.

Until android receive a major change, putting even the most powerful silicone will not eliminate the stuttering..

The iPhone is smooth because ios was made for touch in the first place.. So does windows phone and bb10.. Android on the other hand, was plagued by bad optimization because the first version of android wasn't made for touch.. And it's been carried on until now..

However, ios are using animations to make their interface appear smoother, but it also make it slower.. this is where android excels, speed..

[G2 Q&A, Help & Troubleshooting] Billy Madison:
It can't be found, it's inherent to inner workings of respictive OSes, iOS and Android. Look http://www.youtube.com/watch?v=E406xXr4Mok#t=120 he shows that even Nexus 4 by itself lags. And somewhere in that video or Nexus 4 review (it's here http://www.youtube.com/watch?v=jqHOcwzT5eY#t=202) he compares and shows scrolling on Nexus 4 and iPhone5

The reason is the way GUI works, Android is truly multitasking OS and when you touch screen with finger it continues to work on other tasks. iOS in contrast stops everything every background activities and only react on finger movements, that's why it's SOOOOO smooth. In Android it would take inner internals rework to make GUI as responsive as on iOS, it doubt it will happen before Android 5.0 be released

Disabling thermal CPU throttling is dangerous, I wouldn't recommend it. You'll probably get lots of reboots when it hits thermal max and shuts down so the CPU doesn't burn out.

Words for the wise; but thusfar i have had no crashes, reboots, abnormal overheating to date, and i assume the risk for my personal device.

I've noticed all android phones including the Nexus 4 having this issue. I think the galaxy nexus was pretty smooth, but maybe the iphone has been smoother. Also some of the galaxy s4 units I tested at 2 of 3 Verizon stores had smooth scrolling almost like the iphone and better than any of the other latest androids including the g2. Now they were demo units, so maybe with added apps and usage it starts to lag as some have said the s4 lags, but I'm unsure how the lag comes about for the s4

I also experience frame drops when playing Vector (a really simple game mind you) and Real Racing 3 and Dead Effect and all the other gfx demanding games. I understand that the CPU throttles itself to reduce heat etc but still doesn't mean that it should dumb itself down to the point where I lag during gameplay.

Someone help me with this issue please? I don't want to turn on the "high temperature property" because if I game for a long period of time, i will probably have it running too hot to the point where it fries itself or reboots.

the description of the lag she was encountering are as follow nav bar was very unresponsive would hold home button to pull up recent apps list and it would essentially freeze and take really long to draw,same thing with pull down notification would stutter. when unlocking phone home screen would show up blank then load Very slowly.all her other apps would work instantly and no stutter or lag she had also received systemui.apk force close once when opening task manger and second time just navigating home screen
