[Nexus 7 General] Jordiharrison:
My N7 started to lag after I transferred season 1 & 2 of Falling skies onto it. For the last couple days it has been really bad. Transfer speeds over USB are abysmal, and chrome was nearly unusable. Generally, all reading and writing have taken a huge hit.

I applied Jay's recipe yesterday and noticed a massive increase in speed, but it would randomly freeze for 5-10 seconds at a time, Google Now was pretty much useless as it would freeze while typing. USB transfer speed still sucked.

So today I factory reset it and formatted the internal storage. App responsiveness was nearly like the way it was the day I got it, not quite, but close. USB transfer speed was unchanged. I just reapplied Jay's recipe and it seems faster then it was when I first got it so far. I haven't played with it too much yet too say for sure though. Transfer speed is still completey f*cked at under 1 MB/s... :mad:

First pic is after the reset and reformat w/o Jay's recipe, the second is with it applied, the third was before the reset.
[Nexus 7 General] strikeir13:
Mine also started after pinning the transformers movie. Doing so also gave me less than 1GB space left so it's not clear which might have caused it.
[Nexus 7 General] JakeRoux:
Ditto here, although the lag did not develop immediatly after pinning it. And my lag occurred even though I still had approximately 6GB of storage left on my 16GB device. I eventually did a factory reset, have not repinned the movie, and all is well a week and a half later.
[Nexus 7 General] R1ptide:
Something very odd is going on. I was having lag issues and was getting horrible scores in androbench. Ironically my quadrant scores were great :eek: but we all know how much that is worth. Anyway I'd done a fair share of flashing/tweaking etc although most of my time has been spent on AOSP. I did a factory reset from the settings menu (this also wipes the SD card, unlike doing it in TWRP which preserves that) and was still getting bad scores similar to those Jordiharrison posted in his first screenshot. One would think that a factory reset would fix pretty much any issue like this.

In order to fix it I had to reflash google's stock image using the toolkit.

Then I got this:

View attachment 1290048

I'm perplexed as to why a factory reset wouldn't fix this.

Now I've flashed CM10 to try out and reloaded all the stuff I had stored on my SD card. Currently I have 9.66GB of free space on CM10 with Trinity Kernel installed and get this:

Still good, I'm going to be tracking this carefully and see if I can figure out whats causing the drop in write speeds once I get it to happen to me again.

I suggest flashing the stock image and seeing if that helps.
[Nexus 7 General] heyodee:
Use a different I/O scheduler, deadline or noop. Or sio if your kernel supports it. But not CFQ
[Nexus 7 General] R1ptide:
If this was directed at me I use deadline on the trinity kernel so the second screenshot was deadline and the first screenshot was whatever scheduler the stock kernel uses as default.
[Nexus 7 General] heyodee:
Default should be CFQ. But deadline is better for me thus far.

What is your current/normal operation temperature? With motley's with zram enabled, multitasking is on a whole other level, but then the temperature is 98F+ even when using 100-1300 freq.
[Nexus 7 General] R1ptide:
Complete idle is around 40C but if doing basic stuff/charging it goes between 40 and 50.

Don't remember what it hits when gaming.

40C is 104F so I don't think you need to worry
[Nexus 7 General] jonmorris:
My N7 did seem to slow a lot when I was running low on storage space and had Currents running - with a lot of pages and images set to sync (no more!).

Google Now still takes ages to load and Facebook - sometimes it doesn't load at all!
[Nexus 7 General] Bryan_:
You described my experience to a T. Websites are also often taking 5-20 seconds to load in both Chrome and Firefox when launched from a separate app.
[Nexus 7 General] larzy:
EXACTLY the same for me...
[Nexus 7 General] parmend:
So basically its the worst parts of the bible .
[Nexus 7 General] Keanen:
I use an application called Flickfolio that syncs my Flickr photos to my device, it was taking up about 3.2gb and since I have cleared this application data it has been smooth sailing for me. I am wondering also if there is a problem with the shared file system that has issued with so many files on it. My Rezound has no issues with this same install.
[Nexus 7 General] parmend:
I really hope they can fix this . This thing is buttery smooth 95% of the time . But when it starts lagging I have to reboot it .
[Nexus 7 General] heyodee:
Try a different I/O scheduler
[Nexus 7 General] burnduck:
I had a lag issue before and did a factory reset, which fixed the issue but after 2 weeks the lag is back :(

Sequential Read 24.26MBps

Sequential Write 0.39MBps

Random Read 7.99MBps 2047.23IOPS

Random Write 0.05MBps 14.83IOPS

Haven't managed to regain the write speed yet.
[Nexus 7 General] beeboss:
Guys, I'm thinking of buying N7 but the issue which is discussed in this topic makes me doubt about it. From what I've read here I didn't understand only one thing: can this issue be fixed in future by Google (software issue) or it's hardware fault which can't be fixed ?
[Nexus 7 General] xT4Z1N4TRx:
For those experiencing lag, how much storage space you guys got free?
[Nexus 7 General] wjchen0:
http://xdaforums.com/showthread.php?p=30989125#post30989125

Maybe the lag caused by bug of database io.

When N7 became lag,the antutu score of database io only 60

Flash stock images using toolkit
[Nexus 7 General] hexxellor:
EDIT: Now that I look at this a second time, my write IOPS is still low as heck isn't it? When I compare my results to others in Androbench my Nexus shows up higher than some in some tests and lower in others.*shrug*

I don't think that is the problem. I uninstalled everything on mine with the exception of the stock applications and androbench and I still had issues. For example I was seeing the same horrible write speeds.

Formatting the user partitions didn't help either (data / sdcard).

My bootloader is unlocked too.

The only thing that fixed it was using fastboot to put the stock ROM back.

For some background, I had used the Nexus Root Toolkit (v1.5.2) to originally root it. Of course now that I flashed it back to stock it's not rooted. I had also installed BusyBox Pro, Titanium Backup, was using SuperSU, etc.

There was one thing that was strange though, my benchmarks from Androbench are back to normal now --

27MB RD

10MB WR

1917 IOPS RD

134 IOPS WR

58 TPS INSERT / 59 UPDATE / 62 DELETE

111 BROWSER / 265 MARKET / 293 CAMERA / 722 CAMCORDER

But before I flash it back to stock I recall all terrible values EXCEPT for the last row. Each one of those (Browser, Market, etc.) was greater than 1000, with a couple (don't remember which ones but I think Browser & Market) were around 1700-1800.

That makes no sense why that would be better when everything else was horrible.

I first noticed the issue when TCP connections would fail in applications. Finally I was able to tell just by launching an FTP server and trying to transfer 40MB to my Nexus 7; it would timeout halfway through with terrible transfer rates. Now that I am back to stock I don't have those issues and it flies.

I'm so confused as to how this could happen.... I monitored the CPU and disk activitiy and it didn't SEEM to be doing much of anything abnormal when it was lagging yet I was having these problems.

:(
[Nexus 7 General] Keanen:
I have a 16gb and had at least 2 free when it was happening.
[Nexus 7 General] craig0r:
We don't really know if it can be fixed. I would personally wait until Google releases an update before buying one.
[Nexus 7 General] androidkid311:
This is the best answer you could get and its what I'm doing as well. After mine was lagging(hence this thread) I was confused! Its quad core...jelly bean...1GB ram... but anyway I know Google know of the issue...if they have been paying attention and just want to know what are they going to do about it.. I'm holding until end of September if nothing.. I'll get the Sammy P10 I believe..
[Nexus 7 General] OperationMove:
One thing I did that may cause some of you some lag...

I understand this may only apply to a few of you, but I had a TON of lag when restoring titanium backups from my phone (SGS2 running JB) to my N7, so that I didn't have to mess with settings and saves. I know you shouldn't but it always worked smooth on my kindle fire. One of them was apex launcher. It would do nothing but freeze, mess up, FC, hardcore lagging, misclick, etc. I reflashed different roms and tried them, to no avail.

Then I just downloaded all the apps fresh (as much as I didnt want to redo all the settings) and viola... a fresh install on Apex got rid of alot of my issues right away. I also noticed although my phone and tab were on the same Android version and apex version, the "Apex settings" in the menu were actually slightly different. Perhaps because it knows you're on a phablet instead of a phone.

Obviously most of you aren't experiencing lag due to this, it goes much deeper than that... but this will cause a ton of lag and confusion for some of the newer folks out there. Just figured I'd mention it in case one noob reads this and it helps them. Thanks!
[Nexus 7 General] Cor-master:
Yeah you gotta be careful what you restore with tb. Typically I just use it for game saves
[Nexus 7 General] Moosh:
Hello all

I have experienced the lag issue that's been described in this thread. At first I thought I had a faulty Nexus, but of dawned on me that it might actually be a software issue, specifically SwiftKey 3.

I've tried both the tablet and mobile versions of the software (free) and after a a short time (a couple of hours), my Nexus would become very unresponsive. As one poster described, it was like constantly trying to drag something across the screen but letting it go, which I wasn't.

It got so bad and frustrating that all I could do was reinstall the factory ROM to fix it.

Anyway, a few days ago I followed Jay Aristide's brilliant post and my Nexus is flying along (SlimBean ROM), and yesterday I purchased the mobile version of SwiftKey in the sale.

On my Galaxy S, SwiftKey is fine, but it killed the responsiveness on my Nexus until I uninstalled it and power cycled it. So, in my case at least, I'm certain it's a software issue and more specifically, caused by SwiftKey.

Cheers

Moosh
[Nexus 7 General] Keanen:
Interesting theory, I have been pretty good since uninstalling Flickfolio. I do have Swiftkey, how many of us are using it?
[Nexus 7 General] espionage724:
Maybe try clearing caches/dalvik (I think both are possible on stock, not entirely sure though).
[Nexus 7 General] 0Reefa:
Getting rid of Nova and going back to stock launcher has fixed my lag issues..

Noticed constant high CPU usage in System Panel with none of the process showing any usage but as soon as I cleared defaults on Nova and switched back everything has been good!
[Nexus 7 General] immajew69:
these storage speeds are abysmal. Im gonna call up asus because im pretty sure its a hardware defect. cant wait for my shiny new nexus
[Nexus 7 General] veeman:
No lag at all.
[Nexus 7 General] twcook:
Evil Swiftkey?

Curious. I turned off Currents background sync and uninstalled Swiftkey 3 Tablet, and my lag situation is dramatically improved. Guess I should turn Currents back on to see if Swiftkey really was the culprit.
[Nexus 7 General] 0Reefa:
Was that the tablet version of swiftkey?
[Nexus 7 General] jonmorris:
I use the mobile version of SwiftKey and haven't tried disabling it. Stopping the syncing on Currents seemed to make the biggest improvement and now it's pretty much okay, except Facebook still fails to load a lot of the time (asking if I want to wait or quit before showing anything).
[Nexus 7 General] hexxellor:
I am. I've been using the tablet version since day 1.

Still am, and just manually flashed back to stock and re-rooted but this time I did it by hand instead of using the root toolkit. It's been more than a day and it's still doing well. I am still using SwiftKey though....
[Nexus 7 General] kingofthebraves:
Ive also experienced lag on my device running mcr and i thought it had something to do with Facebook app or torrent app in the background. I flashed to slim beam and everything silky smooth now even with torrenrs downloading and thw buggy fb app running

[Nexus 7 General] SirFork:
I guess I'm spoiled by the performance of the s4 version of the HOX but I thought the tegra 3 was supposed to be the superior gaming machine. Even if I push the cpu and gpu to the highest oc possible with motley kernel I still get more drops in frame rate than the one x stock. I don't notice much improvement at all actually between stock speeds and oc on the n7. I know it's a cheap tablet but it should perform better, but maybe I'm just spoiled by the s4
[Galaxy S III Q&A, (US Carriers)] chipstien:
So I have a pretty generic question. I know how to add pictures to my contacts but am curious how to add a picture to myself. Example.... in the SMS app, I would like to see my picture on my outgoing texts. Seems redundant and silly but I am somewhat anal about this. Lol. Anyone know how to do this?

For the record, I am on AOKP if it matters. Thanks

I'm currently downloading it. Will update you all once it is installed.

UPDATE

----------------------------------------

It appears that if you are using a custom ROM, you need to flash a Samsung stock ROM first before flashing the ICS ROM.

Stock ROMs can be found in the Galaxy tab plus Android development forum if you need to download one.

How can I install it?

If I use Kies (on mac) it said that the device doesn't support upgrade from kies...

Can I use odin? Does exists a guide?

[Samsung Galaxy Tab Plus] RayLovesick:
Just flashed it, everything looking great. Used Odin 1.85. No problems coming from stock rooted. Woohoo!
[Samsung Galaxy Tab Plus] Rozao21:
RayLovesick could check if the rom has the Portuguese language of Brazil ?
[Samsung Galaxy Tab Plus] RayLovesick:
Sure does! Gotta say, operation of the tab is silky smooth after the update.
[Samsung Galaxy Tab Plus] Rozao21:
Better than last build of cyanogenmod 9?
[Samsung Galaxy Tab Plus] RayLovesick:
I can't really comment on that as I have never flashed any CM9 builds. But it does seem like night and day coming from the stock Honeycomb experience. Much more fluid animations, better overall responsiveness, and bluetooth controllers seem to work without that laggy response, so now I can use my iControlPad for mobile gaming. Very happy with it!
[Samsung Galaxy Tab Plus] prmax:
I am guessing you lost root with the ICS flash?
[Samsung Galaxy Tab Plus] RayLovesick:
Correct.
[Samsung Galaxy Tab Plus] memoreks:
Ok, I have it installed.

Download is about 500MB, and it was a little slower than I would like but I was downloading it over a 3G connection.

It went on fine with Odin 1.85, taking about 5 minutes to flash.

On reboot, it recompiles the Dalvik cache, and loads up. It lost my DPI change (no big deal) and my homescreen configuration, but all my software and other settings appear to be intact. Internal SD and microSD card are both left alone during the flash process.

Scrolling is very smooth, much smoother than in 3.2. The notification bar (bottom right of the screen) seems busier than it was before. Icons seem bigger but nicer. It feels much quicker than it used to. I found 3.2 a bit of a pig performance wise, whereas this 4.0.4 build seems much nicer.

WiFi is working perfectly with my Huawei E586 3G WiFi hotspot, but I haven't tested it with anything else. It mounts as a media device fine on Windows 7 too. I haven't checked bluetooth to see if it is working as expected.

So far so good. I've yet to put Chrome on there, but that's next on my list :)

If anyone else wants me to test something, let me know.
[Samsung Galaxy Tab Plus] greenaar:

Worked on my US model via odin. 5-7 min for flash + first boot, everything looks good so far.
[Samsung Galaxy Tab Plus] SWFlyerUK:
Just flashing now.

Although HC isn't that different than ICS, i've been looking forward to it.

I can use Apex Launcher on there for a start, I like the developer options, the ability to force 2D rendering in all apps for a start and limit the background processes.

Cool :)

Working fine on Brazilian 6210 installed using mobile Odin (recommended, didn't need the pc for anything). I think the same number of languages are supported on this version, but the built in Swype only has the European portuguese.

Canadian GT-P6210 w/ UK ICS update

I tried the UK update as well but no luck with the wifi. It won't connect to either of my routers no matter if I'm using WPA or no security at all. In addition there was a period where the wifi just kept switching itself on and off.

I guess I'll try the US ICS update from sammobile and post back later on my (hopefully) success.
[Samsung Galaxy Tab Plus] bjstirling:
Canadian GT-P6210 w/ UK ICS update

OK, this worked a lot better. I did have some brief problems just after the install but once I cleared the cache and did a factory reset things have been working quite well. Internet through wifi has been working a few hours straight now and I haven't noticed any problems.

Just to be clear I was originally using the Canadian LB2 firmware then updated to the UK LPN firmware (which was OK except the wifi did not work) then reflashed the US 6210UELPC firmware right over the UK version using Odin 1.85.

Thanks to this thread I understood everything I was doing (for the most part).
[Samsung Galaxy Tab Plus] SWFlyerUK:
I've flashed it but it's taking longer than that, it's not a bootloop either, my PC is also installing the drivers successfully.

I've re-flashed once, but guess i'll keep waiting.

If it was a bootloop, then that silly Samsung animation would appear.

Has anyone gone from the Fast Form ROM to this with success? I'm hesistant to try it just yet
[Samsung Galaxy Tab Plus] SWFlyerUK:
Interesting you say that - I was on Galaxy HD and had issues with upgrading.

I starting by flashing ICS, it wouldn't boot, even after 40 minutes of leaving it alone.

I went back into ODIN and flashed the LA3 firmware that was already on there, but when I booted the device, I got errors saying that some .logs couldn't be opened the device wouldn't boot, so....

I reflashed ICS, again, wouldn't boot, went into recovery, wipe cache, factory reset, reboot device and ICS started up almost straight away.

Can't beleive how smooth this is, it's a totally different device from HC.

Jellybean ROM anyone?

I'm working on a clean movers build for Fast Form ROM users. All your stuff should move over safely once it's finished. *Hopefully* Well maybe I might not publish it since I'm getting close to releasing a major ROM with Ace, but we'll see how long it takes to tweak with ICS for this P6210!
