My WiFi worked fine I had issues with cell network. Blazing fast now I'm back on 4.2.2 WiFi seems faster too. Hopefully Verizon releases 4.3 soon
[Samsung Galaxy Nexus] liveMike:
Well you lose all of your settings so you need to reset them. You can get your apps back into place though with titanium or mybackup. I have back ups (nandroids) of my favorite roms so i usually just revert back then update to the latest version which is usually a pretty painless task. i tend to switch between aokp/cm/carbon/and now pacman rom.
[Samsung Galaxy Nexus] 96accord:
Yeah I did a factory reset when I updated from 4.2.2 to 4.3.1 AOKP so I don't mind redownloading my apps or losing my text messages.
[Samsung Galaxy Nexus] Card83:
That's the one thing that keeps me on 4.2 ROMs. I live in the downtown area of my city, and have a wonderful 4G connection from home. But where I work (well outside the city), I generally can keep a 3G signal in most buildings, but occasionally lose all data connection. It's a pain in the butt to have to reboot my phone every hour or so.
[Samsung Galaxy Nexus] ahmadairfan:
How did you do that? I heard 4.3.1 roms aren't close enough to be a daily driver...

Btw you should try PSX rom, speeedd:p
[Samsung Galaxy Nexus] prbadboy69:
really hope verizon corrects the data issue..but so far some 4.3.1 roms are becoming daily drivers. i use slim..some data issue but not alot. maybe on 4.4 update big red can release the drivers.
[Samsung Galaxy Nexus] 96accord:
Data issues FTL! It seems if I lose data service it won't come back without a reboot.. :(

I know. I know. I'm not the only one with this issue.

AOKP 10/18 nightly build.
[Samsung Galaxy Nexus] tshelby73:
Data issues seem bad on all 4.3 Roms tried pretty much all of the ones that say it's fixed. It's not to bad in good signal areas but in low signal areas it's terrible. It says it's connected and blue but takes forever to transfer data. 4.2.2 been fine. Verizon needs to release 4.3 on gn. Already rolling to their flagship phones maybe someone can figure something out from those updates.
[Samsung Galaxy Nexus] VuDuCuRSe:
I'm pretty confident that there's some sort of memory leak on some system process.

You can see from the following screenshots that the user apps RAM usage is basically the same throughout the days, but the non-user RAM usage increases a lot.

Screenshot_2013-09-22-17-14-16.png was taken right after a reboot and had around 200px of Runing/user RAM on that blue bar.

The last 3 screenshots shows the RAM usage from moments ago, where the Running/User RAM is below 200px wide on that blue bar, but there's almost no free RAM and the device is now lagging as hell.

I'm using a CM 4.3 nightly from last week but I confirm this also happened on CM 4.2.2.
[Samsung Galaxy Nexus] pfmiller:
Yeah, of they are serious about improving memory usage in 4.4, plugging this leak should be step one.
[Samsung Galaxy Nexus] vojkan22:
this is CM you're talking about. stock 4.3 doesn't behave like that. unfortunately, 99% of the custom roms are based upon CM, so they all have those mem leaks. too bad that for a phone like this (nexus, developer phone etc etc) there are maybe 2 or 3 functional ROMs where you can actually use multitasking like it is meant to be used... I gave up on that issue long time ago, found a ROM that doesn't have leak (cataclysm) and settled with it.
[Samsung Galaxy Nexus] pfmiller:
I don't use CM, I run stock and it does the same thing. The system memory use does grow over time making other apps restart more frequently.
[Samsung Galaxy Nexus] vojkan22:
after how long? I've actually never managed to go more than 3-4 days without reboot, but in that period, I've never had any major leaks.

on custom roms it's visible after couple of hours unfortunately...
[Samsung Galaxy Nexus] pfmiller:
I usually notice after a day or two. It may be noticeable after a few hours, haven't really checked.
[Samsung Galaxy Nexus] vojkan22:
Then I think something is wrong with your setup, it isn't a 4.3 problem for sure...
[Samsung Galaxy Nexus] lambofgod13:
There's a mod to get an extra 1g of ram?
[Samsung Galaxy Nexus] nomad4ever:
It's actually not behaving like real RAM, but it boosts the performance somewhat.. Try to find the thread of that Turbo Boost Mod... I'm on mobile currently, can't look it up now...
[Samsung Galaxy Nexus] jsomaniax:
I have had my GNEX for two years and have gone through many many roms, they all lag over time to the point that it's unusable. Happy to report that I finally found a solution so I can keep this phone for another year.

I also use an app call greenify to hibernate certain troublesome apps like chrome and facebook when it's not in use.

Supernova V5 + Mpokang V10 Super RAM (Row/Interactive) - RUNS SMOOTH, VERY STABLE, NO LAG, DECENT BATTERY LIFE, LIKE A BRAND NEW PHONE.

Note: Mpokang kernel increases usable ram from 695 to 772mb. Trade off is only 720p video recording. No 1080p

[Samsung Galaxy Nexus] Keef86:
My GNex stopped flying after 3 months or so, had to restock. I generally have the impression it gets slower the less free storage you have!
[Samsung Galaxy Nexus] VuDuCuRSe:
Try going a week or so without Greenify or other apps that kill processes and use other tricks to free RAM.
[Samsung Galaxy Nexus] Seraz007:
Not physical RAM

Mod is Turbo Boost (search it on xda)
[Samsung Galaxy Nexus] lambofgod13:

[Samsung Galaxy Nexus] joytsay:
use Lagfix, it force trims memory, without all the 4.3 restrictions.

[Samsung Galaxy Nexus] rnagenetics:
Looks like revolt isn't out for Toro..bummer. Unless I missed something.
[Samsung Galaxy Nexus] banditnich:
So the difference is in API not in the UI... Thanks for the explanation...

because when look a while back at 4.3 leak image (like below), I thought the UI will be different

According to Android Police :

But I only get Choose wallpaper when long press on my homescreen... there's no shortcuts. Any idea why?
[Samsung Galaxy Nexus] madd0g:
"The new Nexus 7 (2013) with Android 4.3 includes support for fstrim, essentially idle garbage collection, which TRIMs the eMMC when a few conditions are met – the device is idle, screen off, and battery above roughly 70-percent. I’m told that TRIM support has been part of the eMMC standard since around 4.2, it was just a matter of enabling it in software. The result is that the new Nexus 7 shouldn’t have these aging affects at all. Oh, better yet, fstrim support has also been added to the old Nexus 7 with as of the Android 4.3 update, so if you’re got one of those that feel slow, I/O performance should get better after fstrim runs in the background. "

So no need to jerk around with "lagfix".

Custom launcher have this, not stock.
[Samsung Galaxy Nexus] banditnich:
Oh IC... thanks madd0g

So the fstrim support included on all Android 4.3 right? including Gnex 4.3...

Or only on Nexus 7 4.3?
[Samsung Galaxy Nexus] madd0g:
As the article says, it's in 4.3 - meaning every device running 4.3 uses those. Hence why the GN gained performance again.
[Samsung Galaxy Nexus] banditnich:
Great feature then... maybe that's why 4.3 feels buttery and snappy right now :good:
[Samsung Galaxy Nexus] Kirian:
Is there some kind of way to check wheter or not it's running on the background? Just to confirm.
[Samsung Galaxy Nexus] madd0g:
Maybe in the logcat, but the whole point is that it's not obvious to the user, regular user doesn't give a **** about trim.
[Samsung Galaxy Nexus] Kirian:
Yeah, I just wanted to know if it was really running so I could stop worrying about the fstrim thing at all, but this piece of information is nowhere to be found on the internet :/
[Samsung Galaxy Nexus] Pecata:
Everything has been great so far..love the update! The only thing I have noticed is that before I had no lag scrolling to n Google+ app and now is very noticeable especially when there are pictures...anyone else noticed that?
[Samsung Galaxy Nexus] whitedragonz83:
4 days uptime so far on 4.3 stock everything. While I have not noticed any lag issues, I have noticed RAM used under "idle" went from ~400MB when I first booted it to ~550-600MB after 4 days. Under Settings->Apps->Running, none of the apps there appear different/larger than they were at the start. Though now the constant Facebook, Google Music apps will occasionally be "restarting" as it has to force them out of RAM briefly.

Does this sound like the Android OS is having some memory leaks still?
[Samsung Galaxy Nexus] madd0g:
Nah, our phone is really on the limit with RAM actually, 700MB user accessible RAM just ain't enough nowadays.
[Samsung Galaxy Nexus] Namarrgon:
I'm of the opinion that RAM is there to be used, particularly for caching. Doesn't matter how much RAM is free; all that matters is how much *can* be used if required, and how quickly it can be freed up for use.

What you're seeing is likely just due to caching - as apps load data from storage or network, it's wise to keep it around just in case - so long as they're prepared to quickly let it go when something else needs the memory more.
[Samsung Galaxy Nexus] NexusHeat:
This. It would be nice if it showed a breakdown of how the RAM was being used like in Windows 7 and 8 so we wouldn't have to hear all these ridiculous posts about how each Android update is getting worse with memory management just because there is less free RAM than the last update. The amount of free RAM doesn't necessarily mean anything!
[Samsung Galaxy Nexus] AGoogleUser:
I can't wait for 4.3. But my device is a toroplus. Let's see how long I have to wait this time.
[Samsung Galaxy Nexus] pfmiller:
The running apps memory stats already break down memory pretty well. System, apps, and cache can all be seen. And cache shows up under free memory, so it doesn't make it look like the cache is using memory.
[Samsung Galaxy Nexus] zAlbee:
^This. Cached memory is considered part of free RAM. Less free RAM = less RAM for caching, so please don't use caching to explain it. It's caused by higher memory usage by foreground apps. I'm tired of hearing this bull**** excuse from people who don't understand how memory works. It's just plain wrong.

[Samsung Galaxy Nexus] polar775:
awesome update..

phone definitely feels a lot smoother and battery life has gotten a bit better.

it also seems to have fixed an issue i had with wifi dropping every time my phone screen times out
[Samsung Galaxy Nexus] whitedragonz83:
I guess the issue is that apps do not clear their cache well.

Example 1, Fresh Boot:

I can open Google Chrome and Lux Auto Brightness is fine

Example 2, ~2-3 days of usage:

I open Google Chrome and Lux Auto Brightness is in an endless bootloop until I leave Google Chrome.

If my Foreground apps are identical in both examples, this would indicate it has to do with Android poorly handling cache of apps that should have been killed. Correct? This also coincides with typically very very very little 'cached RAM' / 'free RAM'.

Maybe the problem is what someone else mentioned in this thread or another, that ~700 MB RAM doesn't work well enough anymore for our Galaxy Nexus and we need ~1GB to really be comfortable without the problem I have above.

Maybe it just is Google Chrome uses an excessive amount of RAM (too much) as I never have this problem with any other app.
[Samsung Galaxy Nexus] pfmiller:
Yes, Chrome does absolutly use excessive amounts of RAM. Other new Google apps are getting bloated too (like Hangouts) but for my phone Chrome is the only app that ever causes me to run out of memory. It's a pig.
[Samsung Galaxy Nexus] rauldom333:
All the 4.3 roms I've tried seem to run pretty smooth on my phone. Went back to MMuzzy's 4.2.2 because it kept hanging at the Google Logo after any reboot. Anyone else hear about this issue?
[Samsung Galaxy Nexus] Nexusaurus:
Can anybody confirm if JB 4.3 bring the new camera interface which we saw in early Google Edition S4 leaks?
[Samsung Galaxy Nexus] Pecata:
Yes it sure does. I got the update on Friday-GN Takju.
[Samsung Galaxy Nexus] syspanic:
Does anyone had problems with the Face Unlock feature?

I've received the OTA this morning and since then my face unlock doesn't work anymore, with the error message: "Face Unlock couldn't start"

Anyone else with this?
[Samsung Galaxy Nexus] Gafanhotz:
I... Disagree with the title of the post. I had an crappy experience. Had to revert back to 4.2. It was very traumatic.
[Samsung Galaxy Nexus] Alton (Halo 2):
4.3 is slow for me also reverted back to 4.2
[Samsung Galaxy Nexus] matteventu:
Same here... I just come back to Cyano 10.1, a lot faster and smoother.
[Samsung Galaxy Nexus] CADude:
The people with the slower phones must be doing something horribly wrong.
[Samsung Galaxy Nexus] DroidOnRoids:
Agreed. I had my phone up for 60 hours straight without a reboot and it was rock solid and fast. 4.2.2 would not be able to go that long of a stretch without a reboot. I'm very happy with this update.
[Samsung Galaxy Nexus] mfdemicco:
Fancy kernel has it built-in.
[Samsung Galaxy Nexus] Namarrgon:
That would be System cache, certainly, but are you sure it includes all caching from all apps as well?

When Chrome downloads a page, it caches the images and DOM structure in RAM for future display, and will free this (and reload from storage or network) if asked, but I'm not aware if this memory is tagged as Cache (rather than as Apps) for the Settings display, though that is certainly its function. Many apps allocate RAM for temporary storage, which they will free in onLowMemory() etc, but I don't think that all of them will advertise the exact amounts used as cache to the system.

That could be due to memory that has leaked in the past couple of days, or it could be memory that is being held onto by apps that are still running in the background, or it could possibly be unused memory that hasn't been garbage-collected yet (though this should certainly have happened earlier if apps are failing due to low RAM). It's also quite possible that Lux Auto Brightness has bugs in its low-memory handling, given its behaviour. Hard to be certain without seeing more data on what's happening under the hood, but most/all caches ought to have been freed at that point.

It's certainly true that Chrome requires a lot of RAM. Web pages are big these days, and increased performance often requires increased memory usage. You could of course browse with less RAM than Chrome uses, but there'd almost certainly be a corresponding performance penalty. madd0g is absolutely right that more RAM is needed for today's apps & usage.
[Samsung Galaxy Nexus] lchiu7:
I got the download announcement also but my phone is rooted on 4.2.2. I did install SU and I am on SU 1.51 The standard method of updating the SU code worked fine.

Has anybody done the upgrade with a rooted device and did it go okay? I suspect I will lose root which I can handle but I don't want to end up with a brick.

Or should I unroot the phone first?

Thanks
[Samsung Galaxy Nexus] madd0g:
Um, no it doesn't.
[Samsung Galaxy Nexus] fux0r99:
You will of course lose root when upgrading to 4.3, just reroot an flash custom recovery an supersu 1.51 zip or do what I did an use a toolkit an get on with life.
[Samsung Galaxy Nexus] mfdemicco:
Yes it does. Read the OP. Trimming for "/system, /data, /cache."

4.3 seems to add no new features, fixes some bugs, and seems to add new ones. I'll wait a while until things get sorted out.
[Samsung Galaxy Nexus] madd0g:
Lol. Happy waiting (for whatever reason there is).
[Samsung Galaxy Nexus] whitedragonz83:
I decided to resist the urge to reboot my phone after seeing the Lux restarting while using Chrome effect. Your point about websites using a lot of resources (especially Chrome) had me re-evaluate my RAM limitations on the Galaxy Nexus. It appears the only time I ever have serious issues are occasional websites. Many times I use Chrome and there are no issues. So maybe there is still a small memory leak somewhere, but the main issue just is Chrome + specific websites.

Also I found sometimes (since not rebooting) I will find my RAM used to be more 'normal' levels, or 'nearer to a fresh reboot' levels. So maybe like you said too, Garbage Collection hadn't kicked in at the time of my issues.

Thanks for your input as it has helped easy my concerns about app's and their RAM usage.
[Samsung Galaxy Nexus] hoclem24:
I have a Verizon gnex and let me tell you, it's like night and day for me. Running muzzy aosp 4.3 and the phone flies! That's not even what I'm most excited about... Battery life really did improve A LOT. Not that much more on screen time, but idle it drains roughly half as fast now. That was the only thing I missed as a former iPhone user...it had excellent idle battery. Now the gnex seems like it's on board to last a whole day.

I've had it off the charger for about 3 hours, it was at 93% when I woke up (got unplugged by the damn cat) and it is now at 90%, stock battery. I'm more than pleased! Way to go google, and way to go devs, since I probably wouldn't see this until December if I waited for Verizon's update. And I constantly have about 200-300mb ram free.

Overall I'm a happy camper. I love my gnex, and to think I was pondering a new phone just the other day. Nope! Gnex 5ever. :)
[Samsung Galaxy Nexus] andQlimax:
you probably didn't wait enought to see the magic

do couple reboot, leave the phone on charge overnight (so that trims do its work for the first time), reboot..done

anyway the difference it is a LOT noticeable, the touch screen sensibility is really improved and smooth compared to the 4.2.2

I did a dirtly 4.3 flash, and as soon as the phone boot for the first time the touch on the phone was something I never felt, and it's still like that untill today..4.3 rocks
[Samsung Galaxy Nexus] Molitro:
In all seriousness, if 4.2 performs better than 4.3 for you, you're doing something wrong.

We could argue about 4.1, but no way 4.2
[Samsung Galaxy Nexus] andrewk7750:
To me 4.3 runs alot smoother then 4.2. And 4.1.2 on my phone seems to become slow and sluggish after a few days but 4.3 has been going strong for about 3 :thumbup:

Received the OTA last night and from the first moment, once the phone settled after the reboot, it was obviously a lot smother than 4.2. Google Now loads a lot faster , and even the camera lag when turning the phone is now bearable. Very happy, and I´ll at least wait until the next Nexus, and then we´ll see...
[Samsung Galaxy Nexus] fux0r99:

Did some tests yesterday. While TRIM support is available for Android 4.3 on the Galaxy Nexus, it seems that TRIM does not work if the device is using encryption. Besides the effect of write amplification over time, there is a sig if I can't overhead with I/O speed when using encryption. Of course, if it is important for you that the data on your phone does go to the wrong hands, then encryption is a must.

Yep.

Nice to see Google take a step back and fix stuff, rather than flaunt new features. I know they're currently working in 5.0, but it's still pretty cool they did that.

Use daily Maps to navigate, Google Music and "Blitzer Plus" (German Speedwarner) at the same Time.

Cataclysm tries to be as close to stock as possible, with minimal mods while CM ROMs are the oposite, giving tons of ways to chance the stock experience......at least that's how I see it.But if you're looking for a technical answer, you should ask a dev

I am aware of that for older ROMs, but since 4.3 is only few weeks old, I somehow doubt that CM could have so many customizations at the moment?
