0.01 rw speed was Exactly what I got when running 4.1.1 after going to less than 3gb free space. I had to factory reset to get up to a stable 0.5 (which seems much less of an improvement than others reported).

My updated n7 is still running at 0.5 rw. I have about 10gb free and Can't detect any lag but seemingly my RW speed is vastly inferior to othrs' who've reported on this thread... I
[Nexus 7 General] tabooki:
I'm in the exact situation. I can't get past the .5

Tried resetting to defaults. Tried the Franco kernel
[Nexus 7 General] jmdearras:
a question; I am on the stock kernel, and need new cifs.ko and md4.ko modules, Anyone here in a position to generate 4.1.2 versions?

Thanks
[Nexus 7 General] czesiu:
Isn't 0,5 normal for random writes?
[Nexus 7 General] mstrk242:
This is not correct, actually. The dpi's the market will accept are:

160, 192, 213, 240, 320.

160 - tablet default. 192 - not sure what it's the default for, but market links will still work with it, 213 - stock nexus 7, 240 - stock hdpi cell phone, etc.....
[Nexus 7 General] osm0sis:
From Neowin:

:good:
[Nexus 7 General] styckx:
0.50MB/s (126ish IOPS) is about the peak of optimal random write speeds.

It's not going to be the most snappy and lag free device in the world seconds after filling up all the empty space.. Give the OS time to do its thing and it'll balance itself out. Even Windows will run sluggish if you fill up your drive so there barely any space left. Once you start going under about 800MB (give or take) free space your performance will drastically be affected the further you go under this. (in Androbench.. You may not see it in normal use).. This is normal. Your device is nearly choked to death what do you expect?

Stellar explanation!

Loving 4.1.2 personally.
[Nexus 7 General] joshtb86:
i can confirm that after using forevergone + 4.1.2 update, my sequential writes are up to 8.5 from .5 and random writes are up to .5 from .01
[Nexus 7 General] khaytsus:
Now that's just freaking weird... You're right, mine says 213 too. It's not a standard DPI at all, however, which makes me wonder why the hell they picked it vs just staying with a standard one like every other device. Few devices land exactly on 120, 160, 240, or 320, they just go with the closest one.
[Nexus 7 General] Dorkington:
2gb free, still pretty fast. 4.1.2 seems to have fixed things so far. *knocks on wood*
[Nexus 7 General] Nexus_Lion:
Yeah, mine is definitely less laggy since the update.
[Nexus 7 General] gleung:
is it just me? my n7 tends to lag when the battery reaches 30% or lower :( running in pa with franco r 22
[Nexus 7 General] BrianDigital:
Well just plain old stock rooted and 3gbs free space
[Nexus 7 General] Dorkington:
Started getting close to 800mb free last night... the N7 started lagging again. Cleared some space back to 1.5gb and all was fine. I assume the magic number is somewhere around 1gb free, if not a little higher...
[Nexus 7 General] volwrath:
No offense, but you are the first person I have seen that says the lag is still there. I filled my Nexus to 149mb and besides a symbol showing low space, the nexus was basically lagfree. I have deleted a video and still have it about 800 megs free, so will watch it, but I think 4.1.2 killed the lagginess. I am on stock rooted btw.
[Nexus 7 General] Dorkington:
No offense taken, just reporting my experiences.

It's lag free when I get above 1gb or so of free space. Which is a MASSIVE improvement over the way it was (I had lag even with 5gb free previous to 4.1.2). We've already seen that results aren't super consistent, so I don't think it's out of the question for you to be fine with 149mb free and for me to have a little lag at 800mb free.

And I should note, 4.1.2 lag with 800mb free, is still better than the lag I had previous to 4.1.2. Previously, I'd tap something and it'd take 30-60 seconds to register at times. The lag in 4.1.2 with 800mb free for me was more like 5-10 seconds. I cleared a few comics to get back to 1.4-1.5gb free and the lag simply gone.
[Nexus 7 General] frank35:
My experience was the same. I installed 4.1.2 and ran forever gone. After that:

0.69 seq write with 1.1gb free

10.91 seq write with 2.8gb free

I haven't played around to find the threshold.
[Nexus 7 General] TheScarecrow:
Am I the only one? When I'm updating apps from Google Play, I get "downloading for 2 or 3 minutes before the downloading actually starts to happen. I don't get this with my Gingerbread phone. Anyone else experiencing this?
[Nexus 7 General] willbeh:
Still laggy after the update and was hovering around 3GB. Uninstall a few app and rebooted, now working OK.
[Nexus 7 General] retskrad:
Im seriously getting tired of Android. How are you supposed to take this amaturish mobile platform when Googles own devices is worse than the OEMs? My galaxy nexus and nexus 7 has been a lag-fest since i bought them. Never android again plz.

At the moment my nexus 7 lags when typing this and having music player in background. You cant be serious Google.

Ill never recommend android again. Frustration the whole way through.
[Nexus 7 General] styckx:
Ever consider maybe it's not the device but the user?
[Nexus 7 General] BrianDigital:
But he flashed all these work in progress modz to make stuff better so that could never be the problem.

Lol did a Google search on that user name mostly troll post and alot of asking how to make Ubuntu look like osx
[Nexus 7 General] rmm200:
I put a lot of stock in the Thanks / Posts ratio.

If the poster has over 400 posts, and under ten percent thanks, that makes a Troll to me or at least someone who does not contribute to the community.
[Nexus 7 General] TheScarecrow:
As I had no response, it must be just mine. So I backup as best I can on a stock device and did a full reset. Its back to how it should be now speedwise and I'm glad about that.

I think Google deserve criticism of the N7. The lag issue, well, these things happen and they have taken action. But their communication has been poor prior to and after 4.1.2 release. This didn't resolve the lag for me, neither did filling and clearing the memory. The lack of a removable SD card and poor support for MTP in Linux made backup/restore difficult and time consuming. The built in restore process failed, I think because the startup wizard couldn't cope with Google's own 2 stage authentication.

This is intended to be a main stream product and in this respect it falls short of what's required. A rock solid backup/restore process, a functioning USB for all operating systems, ability to restore apps data and even home screen layouts. Most of these problems could have been ameliorated by the inclusion of a removable SD Card. This product needs to be criticised so Google can make the next generation Android devices more user friendly.
[Nexus 7 General] DrHenley:
4.1.2 seems to have fixed my lag issues. And I was pulling my hair out before the update...
[Nexus 7 General] alkemist80:
Glad to hear the lag issues seem to be resolved. Under 5 GB left and was starting to get worried.
[Nexus 7 General] ingenious247:
Maybe it's because I only recently got my Nexus 7 and it was updated within minutes of signing in, but I've never experienced any sort of lag at all.. actually really pleased with this tablet. No light bleed, no screen separation, nothing. Great tablet all the way around
[Nexus 7 General] khaytsus:
You do realize the thanks have only been around maybe two years and the default skin that has a button for thanks less than that time?
[Nexus 7 General] TheScarecrow:
Interesting, it was about two years ago the Ubuntu forums dropped the thanks system. I start to understand the reasons why they did that.
[Nexus 7 General] Jay Aristide:
I like the thanks system. It might not seem like it, but I'd imagine it cuts the number of 'thanks for this' posts easily in half...

Not to mention, it makes you feel good when someone thanks you for something useful or helpful you've done. Also, it does help you at least loosely gauge the person you're reading. 1200 posts since 2010 and 18 thanks is a pretty good indication of what you're gonna see if you click 'find all posts by this user'...

But, I'm jaded and have always been a proponent of stereotypes.. they save time
[Nexus 7 General] TheScarecrow:
Well it did upset a lot of people at the time on Ubuntu Forums, but they got over it. It took away a cause of some stress.

I think at the time it was said to be for technical reasons but during and after the furor there never seemed to be any intention to bring it back.
[Nexus 7 General] styckx:
I dig the thank system and always have.. It's rather simple.. Don't act like a moron, be polite, if you're not polite or called out on about your mood admit to it (everyone has bad days) apologize and it's done with, and try to help your fellow man or woman if you have the knowledge they need assistance with.
[Nexus 7 General] Jay Aristide:
That's all just standard ettiquite, to be honest. It's amazing how many well-mannered people leave it all behind as soon as they go online.
[Nexus 7 General] Narwhal73:
Yeah the new update to 4.1.2 caused a little bit of lag for me on my unrooted Nexus 7 16 GB. I was able to fix it by using Forever Gone (SD Card Cleaner)

Works pretty well. May cause your device to freeze and reboot when it reaches 100 MB of capacity left (read app description in Play store for more info) after about 10 minutes it should begin to work again. DO NOT PULL BATTERY. Once its working again release filled storage and you should be lag-free :)
[Nexus 7 General] BrianDigital:
i wonder if xda will ever use a system like reddit, upvotes instead of thanks, and downvotes for the trolls
[Nexus 7 General] styckx:
Doubtful because down votes on Reddit are also used for all the wrong reasons.

For example.. Post on /r/Android really nicely about how much you like XDA. I guarantee you will get down voted into oblivion because bashing XDA on Reddit is a hobby for 90% of them. (they don't like it here very much)
[Nexus 7 General] Jay Aristide:
XDA already has a down vote for trolls function built-in.. It's the report this post button. Trolling, flaming, and general douchebaggery are not permitted here. If you see it, report the post to a mod :)
[Nexus 7 General] khaytsus:
Actually if you had looked at the beta 2013 XDA skin.... But it has been removed.
[Nexus 7 General] TheScarecrow:
Exactly, it's a fine line though between being motivated by wanting to help others or wanting to increase your thanks score. I have difficulty in accepting that a posts to thanks ratio = good guy/bad guy. That certainly screws me as I don't have the technical knowledge to answer questions here.

As for Lag, three days now since I did a factory reset and what a joy to have my zippy smooth Nexus 7 back.
[Nexus 7 General] rmm200:
By the time you have 400 posts here, you will be surprised how much you have learned that you can share. And Thanks are not just for tech info - recommending a Note app you like will garner some too. No one looks at new posters thanks count - it is meaningless.
[Nexus 7 General] chrisomnia1:
Ok, just bought an N7 yesterday and am quite happy with it so far. No defects that i can find, but notice some lag in the browser when scrolling. Is this normal? I can touch the screen and move my finger, but there is a slight delay in responsiveness. Is this an old issue that has been resolved in some way? Any help is appreciated guys, thanks.
[Nexus 7 General] TheScarecrow:
This doesn't sound like the issue discussed in this thread (16GB N7 only) and slight delay scrolling in the browser is a subjective thing. I can't say I see any delay scrolling on mine.

Did it have 4.1.2 installed out of the box? Or did it do an Over The Air (OTA) update shortly after you first used it?

To check look in Settings > About tablet, Android version.
[Nexus 7 General] Jay Aristide:
Root and install the aosp default browser. That alone is worth rooting. Search xda and install the latest adobe flash player for ICS. Voila, flash and a lightning fast browser to boot :)
[Nexus 7 General] TheScarecrow:
In that case, I suggest you do a full factory reset because in my case the benefits of this upgrade only became apparent after doing this. It does mean losing everything on your device but as you just got it that shouldn't be too grave.

Hope this helps if you try it.
[Nexus 7 General] Jay Aristide:
I have 218 apps installed and less than 2gb free on my 16gb. It takes about an hour and a half to completely redo :)
[Nexus 7 General] TheScarecrow:
I know what a pain that is, I did it as a last resort but it was the only thing that worked for me. Took nearly two days to do and get back to the way I wanted it. But this guy said he only just got his N7 so a reset may take just a few minutes. I don't think the 4.1.2 update is fully implemented without a factory reset and that does not happen as part of the OTA.
[Nexus 7 General] jonmorris:
When you do the update, it takes a while to 'optimise' the device.

I would certainly not do the full reset and app reinstallation (I also have well over 100 apps installed) unless absolutely necessary. I certainly wouldn't do it on the off chance it might help things!
[Nexus 7 General] TheScarecrow:
He's only had his N7 for 48 hours, he must be going some to have a ton of Apps installed. On that basis I think its a good bet to do a reset and get it out the way. Like I said, it's the only thing that sorted my N7.
[Nexus 7 General] Dorkington:
As someone with a low thanks ratio, I take offense to that! ;)

Though most of my posts have been questions and generic responses/thanks. I think it's possible to not be a troll, while also not being an awesome contributor and still being a decent member.

YMMV though.

---

On Topic, still the same space 1.4gb ish, still pretty lag free. :good:
[Nexus 7 General] chrisomnia1:
So, factory reset helped i think. Didn't have that many apps so it was easy to try.

I know this isn't the thread for it, but what did you do to your device that helped it the most?

As in, which rom are you running? Kernel? or any other mods?

Thanks for the help guys,

chris

Latest eclipse is great and very fast no lag on my end, the only true lag comes from an app called google chrome, hope android 4.2 is holding an updated version
[Nexus 7 General] Cmmts:
Ok guys. I'm new with my Nexus 7 and read that Google Currents background sync might be causing lag. Has this been actually verified? I'd like to keep the sync on, but at the same time, if it causes performance issues, it isn't a huge deal to turn it off. I'm just asking, because sometimes there seem to be these "magical" fixes to issues that have nothing to do with the actual problem...
[Nexus 7 General] thevuman:
4.09 gbs left on my Nexus and it starting to lag again. started after I installed gta3. Lag occurs in Google now... Bad lag... Boat browser lags a bit and Tapatalk lags.

Ugh.

Don't want to do hard reset, fixed lag last time this happened, because I've invested too much info on here now lol

Stock everything
[Nexus 7 General] ncvikingx97:
Have you considered flashing a ROM. They smooth mine
[Nexus 7 General] rmm200:
Side question - did you condition memory after installing 4.1.2? Somehow you need to get all free memory over-written and released to get the benefits. As with all things Android - there are Apps for that... I used Forever Gone.

Dang memory controllers anyway...
[Nexus 7 General] davidstech11:
I have the 32GB model and so far I haven't noticed any lag. Then again I don't expect it to be perfect. It's a $200 tablet. For the price I paid I am extremely happy with the performance and what I can do to tweak it.
[Nexus 7 General] Uh60m Pilot:
Sent from iphone....... sorry had to point it out. At least this is not the ipad mini thread :)
[Nexus 7 General] davidstech11:
lol. Yeah. I stopped using my iPhone 5 about two weeks after having it and went back to my Galaxy S3. AOKP and the GS3 just does more for me. But since I am getting the Nexus 4 as soon as its available I figured I better use my iPhone for now. It's fast too.

---------- Post added at 06:38 PM ---------- Previous post was at 06:27 PM ----------

As for the iPad Mini, its not that it has lower display resolution than the Nexus 7. Or has no GPS unless you get the even more expensive mobile version. Or that it cannot play HD movies and videos because its a SD device. It's because it does not have them at the price of it. With other tablets offering those things at a way lower price point I cannot support Apple on that. And I been buying the iPad w/3G, 4G every year.

I admit the iPad Mini feels nice and has a good polish to it like my iPad 3 w/LTE. But also look at the price of it. The Mini starts at $329. The iPad starts at $499. Our Nexus 7 starts at $199. With the Nexus 7 offering all it does starting at $199 I can't support the Mini. Not this model at least. We will see what Google and Apple bring for next years model.

Sorry for getting off track. lol.
[Nexus 7 General] thevuman:
Nah... Don't really want to root right now.

I just uninstalled gta3 and so far, lag is no more... Lol

Sad... Wanted to play the game too... Maybe I'll reinstall see if that works
[Nexus 7 General] SilverHedgehog:
Web browsing is really slow for me
[Nexus 7 General] Cmmts:
What browser are you using? If Chrome, try something other like Dolphin HD (without Jetpack) or xScope Pro. Chrome is known for its lag.
[Nexus 7 General] SilverHedgehog:
tried all the browsers
[Nexus 7 General] Jay Aristide:
How's that working out for you?
[Nexus 7 General] darkchazz:
+1

What sad though is that reviewers often compare N7/N10 browsing performance using chrome(since google did not include stock JB browser) to ipad's buttery smooth safari browser..... and well, you know the rest..

Google needs to optimize this piece of trash and bring it up to JB speed soon because it's giving their tablets a bad name....
[Nexus 7 General] khaytsus:
Really?
[Nexus 7 General] SilverHedgehog:
Could be going better. Android fanboys are really making me sad.

In case anyone else has been having similar problems - I was noticing my n7 was getting slow/laggy running cm10 nightlies. I poked around to find out why and noticed I only had 1.4 GB free and the clockworkmod blobs files were taking up over 5 GB. After clearing them out and making a fresh backup everything went back to running smoothly
[Nexus 7 General] yalouf:
So happy that's the lag has gone :D

I now fully enjoy the tablet, NO fear for the lag anymore !
[Nexus 7 General] ydoucare:
Google Play Music stutters here and there. Might go 5 tracks without issue, then it'll randomly stutter for a split second. Might only do it once every few tracks, but it's annoying as ****. I'd use a different music app, but have a lot of my music synced to the cloud.
[Nexus 7 General] BrandoKC:
I haven't rooted my N7 yet, I know GASP :) On bone stock it's running like butter.

My Gnex is running CM Night lies and encounters lag especially when running Google Now.

Bear in mind that CM Nightlies are experimental.
[Nexus 7 General] oasis9389:
I am experiencing some terrible lag since the 4.2/4.2.1 update. I am running a rooted n7 with a stock rom. I've recently tried a new kernel to fix the lag, but that hasn't worked. I have also tried the google currents fix, that hasn't helped.

The lag really only happens in one area/routine. Any time i use the google search and then click a link from the results to go to chrome. The whole tablet basically freezes up.

I am also using swiftkey as my keyboard, for some reason i have a feeling that swiftkey may be causing it b/c the keyboard gets real laggy in search and then it continues into chrome.

any help on this?
[Nexus 7 General] khaytsus:
Nope, I use Swiftkey Tablet and no other keyboard.
[Nexus 7 General] oasis9389:
hmm ok, i uninstalled, gonna play around and a bit, i'll probably re-install. Thanks.
[Nexus 7 General] acegolfer:
Same thing here. I've disabled swift key. Seems to help a bit. Stock keyboard is pretty good if there's no more lag.
[Nexus 7 General] oasis9389:
i un-installed it.. that seemed to help, but i love swiftkey and based on the previous poster i re-installed it. the lag came right back on google search. I then removed a bunch of un-used data/apps and cleared all cache. This has helped the lag, you can still feel it a little bit, but its a lot better than it was.
[Nexus 7 General] hayabusa1300cc:
The lag is ridiculous, it was quite snappy before the both updates...

Has someone bought one off the shelf with the update and have lag?

.:Sent from my Sprint Galaxy Note II:.
[Nexus 7 General] Jay Aristide:
I've updated steadily from 4.1 to 4.1.1 to 4.1.2 to 4.2 to 4.2.1

I'm currently on 4.2.1 and have no lag.

A good friend of mine bought his at Wally-World with 4.1.2 on it, updated it to 4.2.1 and is having no issues.

These aren't supercomputers capable of simulating nuclear explosions in real-time, people. They're low-power, self-cooled mobile devices. There will be times your device slows down. Having been here from the very beginning of the n7, I can tell you with certainty that the lag issue for which this thread was started has been abolished. There's only so much that can be done with the limited bus bandwidth of this device. Try cutting down on the number of things you expect it to be doing at once.
[Nexus 7 General] cub0ne:
have you tried the disableling the google current sync?it works well.
[Nexus 7 General] hayabusa1300cc:
I've disabled it by freezing it long ago and it doesn't help me.

[Nexus 7 General] Bobbyballbags:
I take issue with this.They are not super computers no, but then they are running a mobile operating system that runs smoothly on other devices that have similar specs. I have a nexus 4 which is running almost identicle software. The nexus 4 is more powerful but the performance difference is like night and day. Especially things like chrome and google now, typing in google now sometimes has a 2-3 second delay. The lag since 4.2 has been unreal in certain areas of the OS (the OS, not the third party apps that you might expect a few probs with). I won't comment on the initial reason for the OP posting but for me 4.2 has been a real step backward for me.
[Nexus 7 General] oasis9389:
Guys I have the fix.. Hopefully you check back.

I uninstalled hd widgets and my tablet is back to lag free. Must not agree with the 4.2 update
[Nexus 7 General] androidkid311:
I agree. I find a lot of people make excuses for the lag on the n7. I posted as it annoyed me and I was kind of in shock looking at the specs. I also think 4.2 is a step backwards and hoping Google releases another patch asap!!. :thumbup:
