[Samsung Galaxy Nexus] beekay201:
thought i'd post here, thread already open and all.

to everyone on a custom kernel/rom, that is experiencing lag in systemUI activities (e.g. entering submenus in Settings) AND UV'ing - this is just a quick poll to see if others can experience the same that i did, if you are currently on 4.0.3 stock kernel/rom, sorry it doesn't support undervolting the cpus, so keep reading if you want to.

my normal UV is as in the screenshot below. it's perfectly stable, i've been running it for weeks, no problems at all. for those on mobile right now (i can't see signatures on mobile), i'm on franco kernel nightly6/aosp-dirty (from aosp/master, build dated 23rd Dec)

i normally experience the small lag when going through submenus and back; opening apps; waking the phone (like half a sec from screen off>screen on).. so.. i thought about all the posts i've been reading about abusive UVing (even UV not working with 4.0.3 kernels, which it can). i just decided to add 25mv in each freq - phone got faster. i mean it almost seems like cm speed. :) will test more as the uptime and phone usage go up.

i'll try to get to the facts on this, but i kinda just wanted to erase the placebo effect completely. if someone on the same conditions with considerable UV applied can:

reboot

let android load completely, uncheck settings > dev options > animations (window and transition), check that refered small lags are present

set normal uv voltages of each freq to +25mv each

do you see an improvement, i.e. lag is reduced?

thanks for reading, report back if you can. it's worth a try no? :)
[Samsung Galaxy Nexus] mgoizueta:
No changes in camera (working properly) with the 4.0.2 update but:

-lags on apps/widgets screen

-lags on UI transitions

-slower web browsing

Battery life... not sure yet.

Thanx G.! Hope 4.0.3 save your ass
[Samsung Galaxy Nexus] diegodbm:
I have the same laggy issue... and the keyboard is really slow in twitter client.

Also, in the stock email client theres a laggy when you open an email, tjen go back with the back arrow....
[Samsung Galaxy Nexus] meeporox:
same here. There is a slight 1 sec lag when opening/closing apps. Never noticed it when it was on 4.0.1.

The most annoying thing is the keyboard lag. I noticed that the keyboard is not as smooth, and it is not keeping up with the speed of my typing. I seem to make more typing error since the update.

battery seems to be better but i would rather have smoothness over battery improvement since it wasn't that bad as people have mentioned before.
[Samsung Galaxy Nexus] Tanith:
I was under the impression they update phones based on the IMEI number. So each time a certain range would get the update.
[Samsung Galaxy Nexus] j c m:
Running stock GSM 4.0.2 and haven't noticed any of the issues identified in this thread. Battery life is still great and I haven't noticed any lag in UI?
[Samsung Galaxy Nexus] [hfm]:
I've had it for a few days and have not noticed any of this either. Seems pretty much the same as 4.0.1. There might be the slightest hint of this but it's so insignificant I have trouble figuring out if it's me looking for it or a real issue.
[Samsung Galaxy Nexus] chowy993:
I updated about a week ago and I have seen an improved battery life.

However, I have noticed some lag, but only when switching between the app draw and the homescreens, and on several cpu/gpu intensive games.

For most of the time, there is little difference.

Can I also ask if anyone else is re-experiencing the multitouch bug since upgrading? I had no multitouch problems at all with 4.0.1, but now with 4.0.2, the multitouch bug has resurfaced.
[Samsung Galaxy Nexus] sobanb:
I updated to 4.0.2 for OTG and Wallet capabilities but other that it's fairly laggy. Eagerly awaiting 4.0.3.
[Samsung Galaxy Nexus] case0:
People must be mad if they think 4.0.1 is lag free :confused:

4.0.2 has been smoother for me, and with better battery life. I still have some lag in the launcher but not as bad as 4.0.1.
[Samsung Galaxy Nexus] splus:
I got the 4.0.2 update just few days ago and it is making me crazy! For sure there was some lag even on 4.0.1, but the lag on 4.0.2 is much worse, it wes immediately noticeable after updating, screen response is worse, and using the keyboard is just plain frustrating. Battery life seems better though, but of what use is that when GN lags much more than my old HTC Desire?

Do I have to root and flash a custom ROM just to have a usable phone??
[Samsung Galaxy Nexus] phonatrep:
Same problem here.

Everything was smooth while on 4.0.1

When the auto-update installed 4.0.2, lags and stutters started !

I really hope 4.0.3 will fix this.

I saw that someone tried to reset his phone to factory default (but kept 4.0.2).

It didn't help in his case, but is there anybody else that tried that ?
[Samsung Galaxy Nexus] adrynalyne:
Weird, considering 4.0.2 is faster than 4.0.1.
[Samsung Galaxy Nexus] phonatrep:
Are you speaking about your phone ?

The problem is for all people that see the opposite behaviour.

According to a few messages, the problem is seen on phones that got 4.0.1 and were updated to 4.0.2 (auto-update).

Phones that have been bought with 4.0.2 already installed don't have that problem.

Am I right ?
[Samsung Galaxy Nexus] sishgupta:
There is definitely a lag in the UI in 4.0.2.

I'm pretty sure it was resolved in 4.0.3 but I'm not 100% because I have never run stock 4.0.3.

In the configuration in my signature it is definitely not an issue.
[Samsung Galaxy Nexus] kristovaher:
Yeah there is lag, just that it is easy to miss during casual use, but very noticeable if you're OCD enough about your phones performance (and I am). Even if all background apps are closed it lags at times when pressing certain menu buttons or navigating (even though menu options itself). My Transformer Prime tablet runs 4.0.3 and does not have any lag at all, so either 4.0.3 fixes it or quad-core simply helps there, but I believe it is the former.

I hope they'll get 4.0.3 out for Galaxy Nexus soon, since that was supposed to be base version of Android 4.0 afterall.
[Samsung Galaxy Nexus] phonatrep:
Looks like the 4.0.4 might help us :

Yeh I updated to 4.0.2 and noticed the lag from day one. Bad update lol 4.0.4 should be early march or lay Feb hoping

lag here too, went from yakjuxw.

How do I roll back?? This lag is annoying!!
[Samsung Galaxy Nexus] burner07:
how to update to 4.0.3 from 4.0.2?
[Samsung Galaxy Nexus] Cartman9000:
I just tried to factory reset phone, and I chose to NOT

use google backup when I was offered to do so during new startup(tried both options in case the google backup was including the terrible "4.0.2 LAG" version!, but the problem remain and the 4.0.2 is still there.

How can we roll back? If it cannot be done I will buy the next Iphone! The phone is laggy now in most of the functions .
[Samsung Galaxy Nexus] Cartman9000:
Laggy Nexus after 4.0.2 OTA!!! (Not 4G version)

My Galaxy Nexus (Norwegian - Not 4G version) became laggy after I got the 4.0.2 version. This is NOTICEABLE when pressing the application switcher on-screen button, when selecting an app inside this manager, when scrolling the widget screen - and a little bit elswere inside different menus. All in all I REALLY regret I installed the 4.0.2 OTA!

I had approx 1Gb apps installed which I removed, with to luck.

I also tried to factory reset the phone. When restoring, I also tried NOT using the google backup as I thought the 4.0.2 update could be included in this backup.

Problem is: Version 4.0.2 remain even if I factory reset phone.

It feels like the phone is contaminated, like I installed a virus! If this is not fixed I will buy another phone. It was quite smooth with the 4.0.1 but now it feels really laggy.

Phone is of course "stock" and not changed in any way. I read that this problem is common, and I wonder if there is any way to roll back to v. 4.0.1??

Is there a fix in 4.0.3??

I will appreciate any help!
[Samsung Galaxy Nexus] fnf:
Can you or someone else make a video showing the lag?. 4.0.2 runs great to me.

I'm not saying the phone is completely lag-free (no current iOS, WP or Android phones are as the OS is not real time), but I know for sure the GUI is hardware accelerated for most applications. If it is stuttering, something else is consuming the CPU, or the GPU just cannot handle it.

I'm very sensitive to a non-smooth UI and I know all current phones/tablets -no matter what OS- stutter every now and then. Just that the definition of buttery-smooth is different people to people.

Please post a video for us to see if what you're experiencing is what I'd considered normal. If not we can proceed to determine the culprit.
[Samsung Galaxy Nexus] Cartman9000:
Hello,

just like you I am very sensitive to the smoothness, but I feel that a video will not show you this in a fair way. I use the phone a lot, and when the response time especially for the task switcher function suddenly is 1 sec slower right after 4.o.2, I'm pretty annoyed.

I agree that one shall not expect lag free products but this is surely connected to the update one way or another.

But I will give it a try, I will take my girfriends Nokia N8(now with Belle;-)) and try to make a movie tomorrow. Please follow the tread!

Another funny thing is, SOME web sites are(at least was) very smooth, while others are very non-smooth! Althoug I have no flash installed, and the non-smooth sites have no graphics! How can this be? This was a fact also when I got the phone in December running 4.0.1 .

That said, the Nexus and the ICS is beautiful and the task swither is brilliant!

But I heavy user like me cannot live with updates that slow down.

By the way, can it be rolled back to 4.0.1?
[Samsung Galaxy Nexus] fnf:
If you mean the general performance (minus the UI) reduces after the update then it is most likely caused by apps running in the background or an Android bug. Without knowing how you're using the phone or looking at the logs, it's hard to say. This can be verified by doing the tasks that you'll most likely find lagging right after a reboot. If they perform well then the slowness is caused by cache trashing (caused by rouge apps, too many apps running in the background or low memory). On the other hand, if they perform slowly even after a reboot, it is a system issue.

It would be helpful if you can post screenshots of services and apps running in the background (check out Settings-Apps).

The slowness might be caused by a bug in the browser, or the page containing hidden/complex/nested elements (which tax the CPU much more than simple images). You may want to try a different browser.

Sure, you may need to clear data/factory reset though, else some system apps may force close (configuration issues, apps usually deal well with upgrading, not downgrading).
[Samsung Galaxy Nexus] phonatrep:
This problem didn't appear when people installed new apps, it appeared when 4.0.2 was installed, so I guess it's a system issue.

I see lags in a lot of places :

-When I open the Contacts app (a lot slower than on 4.0.1).

-When I open the Settings (especially Battery information).

-From any app, when I press the Home button, it takes a lot longer to get there.

-From the app list, slide the screens, it lags.

All of these worked perfectly in 4.0.1, then the OAT 4.0.2 installed itself and problems started immediately.

Lots of people that upgraded from 4.0.2 to 4.0.3 or 4.0.4 reported that it fixed the lag problems, so we just have to wait for these upgrades to be available OTA.
[Samsung Galaxy Nexus] Yellow C6:
There's noticeable lag on 4.0.2 which is absent on 4.0.1. It drove me crazy for about a week and but now I'm used to it. I thought about flashing back to stock 4.0.1 but I get much better signal and battery life with 4.0.2 that I stuck with it. People have said 4.0.3 and 4.0.4 doesn't have the lag so I'm hopeful it's just 4.0.2.
[Samsung Galaxy Nexus] timsen11:
So maybe its better to flash a custom rom ? The only problem ist that i dont get OTAs anymore !

Gesendet von meinem Galaxy Nexus mit Tapatalk
[Samsung Galaxy Nexus] Wiggz:
For me the easiest way to recreate the lag (for fnf's purposes) is to go to the Apps Drawer and scroll across and through the widgets....once I hit the widgets I see a noticeable difference.

This is 4.0.2 stock.

another area as people have mentioned is the "recent apps" button.....that seems to lag terribly.

I'll try and make a video later if nobody else does. I'm just hoping for more OTA (4.0.5?) soon.
[Samsung Galaxy Nexus] xdafann:
I had the same problem. I was planning to stay on stock as 4.0.1 was definitely good however 4.0.2 made me make my mind and I just flashed a custom ROM.

So much better now
[Samsung Galaxy Nexus] fnf:
It sounds like it's a system issue after all. I got the same amount of stuttering that you mentioned and thought it was on par with the Nexus. Got the GN on December and flashed to 4.0.2 straight away so I'm not sure how 4.0.1 works.

Still, because it is a system issue. I'm quite relieved as there is nothing else you can do to fix (short of changing to different 4.0.2 ROMs/kernels). Those of you who are annoyed by this can still flash back to 4.0.1 :).
[Samsung Galaxy Nexus] -nrm:
I cannot confirm that the lag is gone in 4.0.3 or 4.0.4. You can check this pretty easily with any game running in UAE4Droid. From 4.0.2 on it is pretty unuseable, although a smooth amiga emulator shouldn't be a problem at all on our phone.

In 4.0.1 everything runs smoothly..
[Samsung Galaxy Nexus] Wiggz:
Absolutely - I'm annoyed by it, but understand that if it worked in 4.0.1 and not in 4.0.2 surely the next OTA will put this back right. I'm actually kind of used to it now so should notice an improvement next OTA :)
[Samsung Galaxy Nexus] tigajr:
+1

No lag at all. Battery lasts over 24h now (GSM), after 4.0.2. The only thing this phone lacks, that I need, is AVRCP 1.3 or 1.4 support. If I get that, maybe with 4.1, this phone will be perfect for me.
[Samsung Galaxy Nexus] Cartman9000:
This is exactly where I also have lag now, widget sreens, and the recent app list. Response time here is poor now. Keyboard is a little bit affected.
[Samsung Galaxy Nexus] RogerPodacter:
Maybe the reason i dont see as much lag is because i am still on 4.0.1 and have not upgraded...?
[Samsung Galaxy Nexus] phonatrep:
Yes.

I had 4.0.1, it was perfect for me, no lag at all, everything was smooth.

Lag started when 4.0.2 installed itself.
[Samsung Galaxy Nexus] kristovaher:
4.0.1 was really good and lag-free for me. But it's been lagging ever since 4.0.2, not noticeably, but for a guy who works on UI's daily, I can easily detect it. Sometimes it's worse, sometimes less, but one way or another it is not the cheesy 'buttery smooth' that everybody said Galaxy Nexus is prior to release.

I also have no non-stock apps running in background and I have even turned off screen animations in hopes to make it faster. But I can still detect it.

I am so surprised that we are still on 4.0.2, to be honest.

Google is not supporting Galaxy Nexus as much as I hoped.
[Samsung Galaxy Nexus] phonatrep:
Here is a discussion hosted by Dianne Hackborn (who works at Google on the Android platform), about the lag problem on Android.

Have a look at Jay Freeman answers (this guy is the creator of Cydia).

I saw quite a bit of lag in 4.0.1, primarily when leaving the app drawer.
[Samsung Galaxy Nexus] charger22:
Is anyone else experience problems with the browser? Its a little laggy but more than that, its somewhat jittery when scrolling slowly, and scrolling/zooming in&out fast does not feel smooth at all. This is in addition to the laggy app/widget transition screens. Is this all 4.02 or is the phone broken :confused:
[Nexus S General] funcliu:
I managed to use logcat to find the download link of the OTA package, just want to know if it differs from the one for 9020T, which many of u that have 9020T got before, but...

You can see the OTA link in the pic; it's same as the one of 9020T.
[Nexus S General] funcliu:
Still can't get into recovery, although I updated it through OTA -- the official way.
[Nexus S General] Stefanauss:
This is getting serious.

If OTA updates on i9023 still leads to broken recovery, doesn't that mean that a new OTA update it's impossible?
[Nexus S General] nickmv:
As long as you can boot to bootloader, you've got a usable phone.

Actually, I take that back, there's a tool that just came out to resurrect even HARD-bricked Nexus S's.
[Nexus S General] cttttt:
What happens instead of recovery popping up, and how are you trying to get into recovery? Maybe you're back at the official version of recovery.

Note that the official firmware will replace the recovery with the official (non clockwork version) on each boot. This can be turned off by moving an obviously named script out of your /system/etc/ directory...which a root enabled adb shell. I think the basename is something like install-recovery.sh.

In any event please confirm why you feel you can't get into recovery and perhaps we can help you out.

[Nexus S General] SlCKB0Y:
By all accounts, the recovery on the i9023 is not broken, you just cant *see* the display due to the AMOLED vs SLCD differences.
[Nexus S General] langers1972:
I updated my i9023 OTA and recovery IS working
[Nexus S General] funcliu:
I tried to select "reboot" in the broken recovery blindly, it works. I guess that the recovery can work properly except the display.
[Nexus S General] _KP:
Can you tell us if anything has changed from the i9020T OTA ?
[Nexus S General] athani:
That's beside the point. An official OTA is not supposed to cause such problems.
[Nexus S General] funcliu:
Well, I do mean I can't get into the stock recovery. If I use fastboot to flash or boot CWM recovery on my phone, everything works well.
[Nexus S General] faizalmzain:
what do u mean by cannot go into recovery?

why you want to go into recovery in the stock ROM in the first place?

or you mean cannot go into CW recovery?

you need to flash custom recovery in fastboot and select recovery and you are good to go.

stock ROM always reflash stock recovery every time you reboot, it's not a bug or broken.
[Nexus S General] funcliu:
Nothing. Judging from the same download link, you can see the OTA package for 9023 I got today and the one of 9020T released yesterday are the same.
[Nexus S General] funcliu:
If I want to flash a rom onto my phone, I would prefer CWM recovery, surely, it's easy to use and convenient.

But if the stock recovery from the stock rom can't work properly, don't you feel a little strange?
[Nexus S General] ferozfero:
jus to make sure is this update ONLY for EUROPEAN I9023...or every i9023 in the world...

I updated with the full rom package (http://xdaforums.com/showpost.php?p=20421407&postcount=289). Full wipe at the end to be sure. You can clearly see the recovery working when you put it at the sunlight under a certain angle... Everything works fine appart from that.

BTW my NS is unrooted and locked.

[Nexus S General] Rickythemaniac:
I live in sweden and I've not yet received the OTA yet, I unrooted and flashed stock 2.3.6 just to be sure to get it, still waiting though
[Nexus S General] Valantin:
What hardware revision you have?

on my i9023 rev52 recovery display don't work....I use the OTA update proposed on my phone
[Nexus S General] m.sabra:
Yes that's true,just wipe your screen from smudges and fingerprints,then run the recovery and put the phone in direct sunlight and you will be able to see the recovery.
[Nexus S General] p.pavljasevic:
Confirmed, in the recovery you van only see the selected item. But its working and present.
[Nexus S General] Niko838:
Doesn't work for me, using a lamp though. The android figure appears for a second and then disappears and the display is black. The touch buttons are lit though, so does that mean that I should be in the recovery and should see the options in direct sunlight?
[Nexus S General] amdpox:
i9023 user from Australia here, installed the update manually yesterday. I do have the issue with recovery, but can confirm that it's just the screen - under a halogen lamp I can successfully navigate the menu; so that's a relief.

Still a little weird that some people with OTA update have not had the issue, though, given that's it the same file. Is it true that the stock i9023 bootloader shows baseband/bootloader version 9020?
[Nexus S General] athani:
Yes. No need to worry on that count.
[Nexus S General] m.sabra:
Just make sure your screen is clear (no smudges and finger prints) when you see the black screen put the phone in the sunlight or any other very bright light (maybe the lamp you used isn't bright enough) and you will be able to see the green robot,click on volume+ and the power button sevral times and you should see the menu.

And for the people asking why the bootloader is showing i9020 and their phone is actually i9023,it's normal and the people with GB could check it and they will find that it's also i9020 so nothing new here,that's because google use the same bootloader and recovery for both models,and the recovery problem is caused by the backlight turning to a very low level so on a SAMOLED screen the recovery will still visible but on a SLCD screen it will become hard to see.
[Nexus S General] langers1972:
Have to apologize for the misunderstanding as I have also got the black screen issue. I thought people were unable to even get to the menu to choose recovery. Sorry I was just a bit too excited! As others have said,seems to be an issue with super amoled and slcd screens and the slcd ones can't easily be seen
[Nexus S General] athani:
Any luck yet?
[Nexus S General] khemist92:
My i9023 has no OTA update too =( Hungarian retail nexus here
[Nexus S General] athani:
OK. Is the update zip 100% same as what I would get as OTA on my I9023? I'm done waiting for the OTA.
[Nexus S General] Lordofminor:
I couldn't wait anymore either.

Downloaded the OTA and updated my rooted and used Android 2.3.6 manually from stock recovery. Everything went well. No problems so far. I have full signal and WiFi works too... It's very smooth!

Gosh, why did I waited for OTA that three days?

athani if you still didn't updated, I suggest you to go with VQ8PQk_V.zip.. It was stated several times already that it's the same OTA as the 'official' one.
