[Nexus 7 General] rmm200:
For all the newcomers - the problem was that 4.0 did not tell the hardware memory controller to trim on deletes.

When memory filled up, lag got horrible.

The real miracle was that 4.1.2 fixed that; memory is now released correctly.

ForeverGone gets an assist, in that it fills your storage with dummy data, then deletes it.

This lets the memory controller truncate correctly..

This is really a security program, but it is very handy in cleaning up the memory.
[Nexus 7 General] T-Keith:
Tried doing this on my laggy nexus and I don't even have currents installed.
[Nexus 7 General] rmm200:
You lost me there - Currents is not an app you install. It just comes with Android, along with a few other Google apps.
[Nexus 7 General] volwrath:
ForeverGone gets a huge assist. Saved my nexus from a wall.

Thank you OP, this worked for me. My nex 7 is working like a beast now. Rrraaawr! This guide needs to be stickied or blown up.
[Nexus 7 General] lrefra:

[Nexus 7 General] TheAtheistReverend:
After installing 4.2 (or any major update), always do a Factory Reset. Then disable your currents sync, and run Forever Gone.

If that doesn't help your lag, your placebo is broken :p

Seriously worked for me though :good:
[Nexus 7 General] rmagruder:
I have an unrooted Nexus 7 running 4.2 and a lot of the time it is buttery smooth, except at a random time, usually in front of someone else, when I need to do something RIGHT NOW, and then the Nexus 7 turns into a rebellious teenager. Lagging and freezing badly.

The only thing I have not tried is a wipe. I just don't want to lose saved games and data, and I know of no way to back then up without being rooted.

Any advice on backing up saved game data so I can wipe without fear?

Because really, it's this or back to 4.1.
[Nexus 7 General] bkmaracas:
Ok why didn't any of you nice people tell me about 'safe mode'? Huh? Huh!?

Hold power button to get power off prompt then press and hold the power off/shutdown button.. Reboots into safe mode.... Tried it just now and its snap city! It disables 3rd party apps.

Many apps will still work some not, but if you can feel the difference then you know its a 3rd party app or widget messing with your program. I have currents disabled btw.

Apparently on reboot all is restored, so its a win win test of your system. I can definitely feel less lag as it was making my normally calm self angry. So now I hunt the app or apps slowing things down.

Suck it and see. :)

Have you looked at My Backup?

Otherwise root that sucka! It is a piece of cake.
[Nexus 7 General] rmagruder:
Yes it won't backup app data without root.

And of course you can't root without unlocking, so I just bit the bullet and did so. No lag so far.... But it's early.
[Nexus 7 General] TheAtheistReverend:
congrats

Glad you dove in for root! Makes life so much easier. Now get adfree from the play store, and you've covered the biggest reason why I root. I'm still running stock rooted because I don't need any more than this.
[Nexus 7 General] rmagruder:
I take it ad free removes ads from apps? Ugh. Dude, I hate ads like everyone else, but if they are the only way a developer gets revenue for their work, I will tolerate them.

I should also note, my Samsung Galaxy Nexus on Verizon has been rooted and ROM'ed so much it isn't funny. But then that's also because Verizon leaves us to die so often. I was hoping it wouldn't be necessary on the Nexus 7. Oh well....

It's multi-user

Dear All,

My N7 lagged after 4.2 update. I disabled Currents and it was better but still lagged. I just removed multi-user and I am back to 4.1.2 smoothness. It lookes like the multi-user is the problem. Google would probably fix this in the next minor update. :)
[Nexus 7 General] Bobbyballbags:
Did you disable the service or do you mean you had multiple users so you removed them?
[Nexus 7 General] fcng:
no more multi-user

Bobby,

I removed my guest user and now I'm back to just one user. Now, everything is butter smooth just like 4.1.2. Therefore, one should only have one user and disable Google Currents' sync function.
[Nexus 7 General] Bobbyballbags:
OK cool. Haven't ever had a second user. Was hoping there was a way to shut down the multi user service which would restore it to majesty.

Forever Gone

I've been running Forever Gone for weeks now, whenever I go below 3G (often down to around 1G free ) on my 32G Nex7, and it's been working fine. Whatever lag I do experience vanishes every time so far, and with so little space left it really doesn't take much time to run.
[Nexus 7 General] AndreaCristiano:
Yes **** is solid
[Nexus 7 General] dellenrules:
This may sound silly, but if I disable Bluetooth, it solves a lot of lag issues.

The Bluetooth in 4.2 has it's problems. Never thought it would affect performance.

I might look into that.

[Nexus 7 General] Nyobie:
Thanks OP!

I found another potential source of lag can be disabled periodically which many of you probably already knew. I've only had my and 7 for a few weeks so I thought I'd share.

Go to settings, data usage, menu, and uncheck auto sync data. Warning: disabling auto sync will prevent syncing of your accounts like Google, Facebook, etc. I just recheck the box when I put my device on a charger and I'm not using it. Makes a big diff with lagginess on my N7.

because kernels for now wont work (must give them time)

i am decided to speed up my device manually

so i installed fastest rom ever ( miui)

seeder entropy generator

v6 supercharger

deleted most of rom apps (gallery, email, calendar etc)

themed everything black, disable sounds etc

disabled some batterysaver tweaks (dynamic contrast etc)

disabled cores ( now it runs single core + lp core) to eliminate hotplugging "lag"

475 - 1300 mhz

now my tablet is little faster 13026 pts in ANTUT (single core)

and still lags on fruit ninja full ( lag for 0.1s is still that damn lag)

fruit ninja thd is not playable for me (wana play multi? not this time hehehe)

what can i do to slightly increase performance

is there something else? what can i do to play 2d game without any lag?

ps. on older devices with lower screen size and ~6000antutu it doesn't lag at all

should i change resolution (not dpi)?

Factory data reset seems to work

I'm running a Nexus 7 and a Galaxy Nexus GSM. They both were smooth with Android 4.1 but lagged quite a bit after upgrading to Android 4.2.

Although the Google Currents fix didn't completely solve the problem for me, I had a significant performance improvement after doing a factory data reset on the Galaxy Nexus. It runs nice and smoothly now. The difference is dramatic, it runs like it did under Android 4.1 and it's definitely not the placebo effect.

I know this is not a convenient quick-fix solution that you are probably seeking. It's less of a scalpel and more of a nuclear weapon, but at least it works. After the next firmware update comes out I'll be doing the same thing to my Nexus 7.
[Nexus 7 General] mercado79:

Too funny

Hahaha, I did the same thing, not so much to show my lady that iOS doesn't rule (it doesn't in most cases) but just to allow her to have all her apps logged in on a separate account. Removing the user didn't fix it but removing currents helped a fair amount.

[Galaxy S III Accessories] hidea:
I just ordered one as well!

I find that the OtterBox cases aren't as well designed as Griffin's Survivor's. Seems that the Griffin team does a better job designing cases, a lot more thoughts go into designing the Survivor cases than the Defenders. Griffin's marketing term is "over engineered".

I've got cases from both companies, for various devices (iPhone 4, iPhone 5, iPad, iPad 3) from both companies and from my personal observation… Griffin's cases are a lot more articulate. For instance, the iPhone 5 Defender case (by OtterBox)'s bottom area are somewhat more exposed than Griffin's, allowing moisture to come into contact with the phone. In the Griffin Survivor iPhone 5, it's got this thin membrane that covers the speakers and mic holes.

The thing I find different about Griffin's more recent cases (mid-2012 models) are exponentially more complicated to put on than the OtterBox cases. Perhaps this is a good thing, as you're not expected the case off your phone very often.

Griffin's design philosophy is rather different than OtterBox's. Griffin's approach is to take the device and insert it into a plastic frame, then wrap silicone shell, and then securing the entire "assembly" with front-plate that protects the face of the device.

Different from the OtterBox, where you place the device into a two-piece plastic frame that snaps together, then lastly wrapping it with a silicone shell. I should also mention, that the design on most OtterBox cases are less "water-proof" than Griffin's.

In the iPhone 5's Defender, the camera cutout at the back is exposed; while with the Griffin's Survivor the camera perfectly covered with a flap. Now, back in the iPhone 4/4S model, this is actually an annoyance as you've got to hold the frap with your finger as you're taking a picture. With the more recent Survivor models, they've redesigned this and made the flap pivot to the base frame. Yes, it can be an annoyance if you wanna take pictures really quick (having to open the flap, etc.) but heh… I like Griffin's approach better. This applies to the Galaxy SIII Survivor case as well. If you compare the photos on Griffin's product page, you can see that the back part of the Survivor case perfectly covers the camera + flash, using a flap.

The aesthetics… well, this is a subjective topic. I do find the mid-2012 OtterBoxes cases are more sleek looking than Griffin's Survivor. Griffin's Survivor does remind me of Master Chief though, especially because of that Squareish bumps, hexagonal texture. It's a lot more military looking than OtterBox's.

Where OtterBox wins is the design on their holster. Griffin's holster design is very minimal, as it barely covers any surface.

To put it short, Griffin's Survivor cases covers more of your phone's surface area more than OtterBox's.

One last note: Griffin's silicone shell is also a lot thicker than OtterBox's. I find it a lot more cushioning. But it's also a lot bulkier than OtterBox.

Damn, I should do a full on comparison.
[Galaxy S III Accessories] Jammol:
Didn't see an answer to this question. How is the screen protector? Is it the same material as the otterbox defender?
[Android Q&A, Help & Troubleshooting] ashyx:
I have managed to port new governors into the kernel for to our project here: h**p://samsungi8320.freeforums.org/portal.php

The kernel is version 2.6.35.7

Even though the governors seem to be working and are available via Cyanogenmod performance settings, there seems to a problem. Randomly the phone will just reboot. I have tried, interactive, interactivex, smartass, smartass2, savagedzen all have the same problem. Even if none of these governors are selected and just the default onedemand is used, the same thing happens.

Also it seems dependent on which rom I use as on one particular rom the phone won't wake from deep sleep.

It seems the problem stems from deep sleep because while the phone is active everything is fine, even when monitoring the phone via logcat I experience no reboots as the cpu doesn't go into deep sleep and simply stays at min frequency which is 250mhz.

Maybe theres is a problem with the way I have ported the governors? I have made required entries to KCONFIG and MAKEFILE in DRIVERS/CPUFREQ and where required to CPUFREQ.H in INCLUDE/LINUX

To compile I then do make menuconfig and select the governors then do make uImage, everything compiles fine.

Has anybody experienced this when adding governors or got any ideas? :(

pros

+very durable

+clocked at 1.3GHz stock

+2MP camera vs nexus 7 1.3MP

+microSD supports up to 32GB (possibly microSDXC 64GB but not confirmed)

+miniHDMI out

+does have root with fully working market and gapps

+bluetooth 3.0

+OTG compatible

+PRICE

cons

-no internal gps

-screen resolution 1024x600 but at 120dpi barely noticable

-no custom roms or kernel yet

-1.3lbs vs 0.75lbs of nexus 7

-battery life is about 6 hrs compared to nexus 7 rated 9.5

best buy keeps changing the price right now... was $129. Then earlier today changed to $169, now its $199. so it keeps moving around... i ordered 3 of them after i bought my first from walmart at 129 during black friday and rooted it and was very impressed with its performance.

i was so heartbent on getting a nexus 7 and was just waiting for 32GB to break $200 barrier but then this tablet popped up and now i forgot about the nexus 7 :)

Good luck getting timely updates with that, or any decent development at that. Most tablets have a very small or non existent scene except for the Asus Transformer and Nexus as far as I can tell.

If they keep putting this thing on sale for $130usd(Walmart Black Friday, Best Buy sale, Woot, etc) then there will be a lot of them out there. It's hands down the best value for a capable 7inch tablet.

I don't understand this post. There are lots and lots of poorly supported Chinese 7 inch tablets for less money than the n7, and some of them are quite good, but what you don't get with any of them is a broad user community and google support. The n7 has one huge flaw (no msd card slot), but is otherwise a great tablet with a huge user community and regular google updates. You really can't compare it to the Chinese tablets.
