[Nexus 7 General] hyperspacey:
As spectacularly useful as this information is, I'm on my third Nexus 7 and continue to have issues with it as a result of memory speed problems, and as such I find these threads somewhat helpful- at least I'm not the only one running into these issues.

My current primary issue is that my N7 will heave issues with so much as streaming Youtube videos if other IO ops are occurring concurrently, to the point where it can't respond to the user input IO stream. Additionally there's clearly some corrupt storage in mine (it can and will hard reset if it writes to certain sectors).

All signs point towards a batch of faulty NAND slipping through on my particular production run that the 4.1.2 lagfix only partially helped with. Asus are notoriously cheap when it comes to their flash storage (hence why ostensibly "premium" items like the Transformer tablet series have IO benchmarks somewhere below a 2010 smartphone), and this has resulted in the problems we're all running around trying to resolve. Frankly I'd sell my current unit and get a 32GB one, but because of the shoddy build quality on some units (such as mine with its amazingly creaky back plate after a year's use) I doubt I'll get decent money for it.
[Nexus 7 General] rhpmorgan:
This DOES work!

I too have used my Nexus 7 for almost a year and it is still my favorite device. But I too had a lot of lag and so I followed the instructions and my lag is gone. it's like a new tablet! I can't wait for the new Nexus 7, I'll order one the first day.
[Nexus 7 General] s1lenz:
which instructions did you follow?
[Nexus 7 General] rhpmorgan:
Instructions followed

I followed the instructions listed on the first page of this thread.

I've noticed my N7 lagging lately when simply swipeing between homescreens or opening a browser and getting a delay when taping in a URL. Glad I found this thread so I know it's not all in my head!

Anyway. It's rooted but apart from that it's stock. 6GB free. Ran AndroBench and was getting Random Write of 0.33MB. Ran Lag Fix and re-benched at 0.32MB. Then ran Forever Gone, booted to recovery, cleared Cache, and re-benched at 0.45MB. Certainly seems snappier now but haven't had enough time on it yet to tell for sure. Will reply back after some decent time on it over the weekend. Thanks for everyones suggestions though :fingers-crossed:
[Nexus 7 General] projectzro:
The only time I experience lag is when I first open the flip cover I have for it. After about 10 seconds it goes away. But the article makes sense , fill the device and then empty some. A lot of people are way too picky. It was a $199 tablet, at least you didn't do what I did and bought a $400 tablet that had the same hardware as the Moto Xoom but with the Harmony chip set and have no support or updates since.
[Nexus 7 General] voyager_s:
Well I've personally experienced the lags and lock ups on both my nexus 7 and Galaxy nexus I have to say. Both times the storage were quite low to about 3 gigs or less.

I wiped the gnex and it fixed the issue for a while then came back again.

On the 7 I uninstalled some apps and deleted some files. Seemed to help a bit there. Been fine for most past since.

The gnex is still giving me trouble. I thought it was hardware related to be honest. And it kind of is I guess if the Samsung memory are to blame. I was about to send it to Samsung for warranty fix but I guess I'll hold on to it for a bit. Try the solution suggested perhaps by the OP.

Can't say I have had this issue. My Nexus 7 runs great and relatively lag free.
[Nexus 7 General] gc84245:
A lot of people are saying it has improved since updating, but I wonder how much of that is just wiping everything and starting clean rather than because of 4.3. Guess we'll see what people who go the ota route without wiping have to say.
[Nexus 7 General] rakeshishere:
It's clean flash syndrome or placebo effect. N7 lags and it's the truth. Period

Waiting to flash OTA on my 3G N7. Looks like it hasn't rolled out yet anywhere and As I agree with article and the OP, I'll post my opinion after few days of testing 4.3
[Nexus 7 General] :
It didn't before 4.2.....and sounds like they fixed it with 4.3....so come back after 4.3 update and comment. Hardware doesn't just start slowing down dude....software does. ;)

And yes....a clean install will help regardless. But people said it lagged with a clean 4.2.2, but not 4.1.2. So hopefully its sorted out now.

[Nexus 7 General] rakeshishere:
I'm using OG N7 only since a month and never tried 4.1.2 or any releases of Android prior to 4.2.2 to comment if it's s/w issue or h/w.

Only know that when I started using it, it was fine but after few days (2weeks) or so it started to lag like crazy. Reboot helped a little and later I heard of lag fix app which made issue kind of a little better.

Even Galaxy Nexus owners complain of buggy 4.2.2 release so need to read their opinion about 4. 3 release. Probably it's s/w which was causing it like you say
[Nexus 7 General] Fotogravin:
I did a dirty flash (just bootloader, boot and system in fastboot, no wipes whatsoever) and yes, 4.3 IS smoother! Important difference: look at the amount of free RAM in 4.3 (about 400 MB free) in comparison to the free RAM in 4.2.2 (about 150 MB or less free).

I just still have lots of phantom touches and non-responsive touchscreen, but it isn't worse than it was. At the times I don't have those problems (they come and go quite randomly) my N7 reacts even smoother to my touches than it did in 4.2.2

[Nexus 7 General] CrazyPeter:
Nonsense. I did a update without wiping (remove the -w from the update script) my n7 noticeably smoother. Never had much in the way of lag, but it's definitely smoother now.

Guessing these people claiming of lag have some dodgy apps installed

[Nexus 7 General] jocke_lulle:
How does your n7 reacts when you install apps? Mine lags a lot! And the screen kind of freezes. I have to wait a bit before I can start to use the device again. I'm all stock 4.2.2, haven't got 4.3 ota yet. Hopefully it will be better with the update. I have had my device since last October. I don't think the lag was so obvious before as it is now

[Nexus 7 General] gc84245:
The only time I get bad lag is if I am downloading or updating apps. That's not just my N7, it happens with my S2 as well. Seems a bit better with 4.3 though.
[Nexus 7 General] frozst:
Seems that we are talking about different devices... :eek:

Even my Nexus One runs smoother. Obviously I can´t run games or super heavy apps, but it doesn´t have any lag after waking up and I can write an email or a whatsapp while I´m updating apps. I can´t say the same of my Nexus 7. Really, it sucks. After waking up (specially using 3G) is super slow... I don't get it, my phone doesn't do that!

It´s true that those 2 apps solve the some issues, but I think that the real problem is that the Nexus 7 has a ****ty memory chip or controller. Period.

I was hopping that the new N7 were from a different manufacturer, but seems that it will be the same laggy tablet.

And of course there is a solution, wipe and only install a few apps and don´t use widgets. Then it will be blazing fast... sure.
[Nexus 7 General] :
Install 4.3, then see. Seems much better.

A lot of apps will need to be updated for 4.3. If some are crashing that could be causing lag too, cause they are trying to start. ;)

Removed from anandtech's nexus 7 2gen mini review:

"One of the big problems was that the slowness which occurred with the prior Nexus 7 took device aging to appear – it was great for the first few months, but after you started loading it things tailed off. 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 version 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. Better yet, fstrim support has also been added to the old Nexus 7 with as of the Android 4.3 update, so if you’ve got a Nexus 7 that feels slow, I/O performance should get better after fstrim runs in the background. I'm checking on whether the other Nexus devices have also had TRIM support added. I would consider the slow storage aging problem fixed as of now, and Google took the eMMC and storage I/O performance issues with the previous Nexus 7 to heart for this version."

So let flash 4.3 as soon as possible :)
[Nexus 7 General] szymon247:
It's because of TRIM in 4.3 that fixes the aging storage memory issue. Also worked wonders on Gnex, apparently.

I wonder why Google went all quiet about it, it's the single most important addition in 4.3 (and the only one warranting this update imho).
[Nexus 7 General] Richieboy67:
Sure, if you fill it with apps and things running in the background it will slow down. I don't think that is a reflection on the device.

As for the new one I think twice the memory should be a vast improvement over the last nex7 though I never had and lag issues or slow downs with mine. I only install and use what I need due to so many app devs filling apps with spyware or at the very least skiing for too many permissions.

It kills me to see how many unneeded apps are set to always run so they can grab phone calls etc. If anything is "aging" your nex 7 it is that crap.

i did a dirty flash over cm10 nightly with 4.3 there is some restored butter with the update. Now when I press the poser button it turns right on and the lock screen is responsive

apps do load faster, dont get me wrong its no where near my n4 but it has speed up this device some

---------- Post added at 02:38 AM ---------- Previous post was at 02:35 AM ----------

these explanations of "oh its your apps" well its bull****, I watch over my apps and I have more installed on my n4 and it runs like butter and my n7 with barely anything installed it does slug along. the 4.3 update def did something as there were some trim commands added so maybe that is the magic.

In a community just going "my device is good your all doing it wrong" doesn't help a damn thing.
[Nexus 7 General] :
And saying 4.2.2 made the nexus 7 a bad tablet doesn't help anything either. As the thread title suggests. It was software, not hardware that was the problem. ;)

here's a real puzzler. Today I noticed that my SD card wasn't mounting anymore. I'm rooted on stock ROM. Everything else seems to be working. It won't mount. I've tried using root Explorer and TWRP. Nothing. Thoughts? Anyone?! TWRP sees the card while I'm in recovery. Once I reboot into stock ROM, I lose it. I try to mount it, then I'm getting a 'safe to remove card' notification.
[T-Mobile Samsung Galaxy S 4] Toleraen:
Stupid question, but have you tried physically re-seating the card? I had odd issues like that on my S2.

Other thought, can you mount the card using a PC?
[T-Mobile Samsung Galaxy S 4] jerzyboy2421:
I've tried reseating the card multiple times with no luck. TWRP will see the card while in recovery. But when I boot into the OS, I lose it. I'm stumped.
[T-Mobile Samsung Galaxy S 4] blakeslee14:
One random thought, and probably isn't your solution ... Is the card formatted with exFAT or ntfs. Gs4 won't natively support ntfs formatted cards. Plug it into ur pc and check the properties... Worth a shot
[T-Mobile Samsung Galaxy S 4] elesbb:
Go into manage apps under settings and clear data for media storage.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
If this was the problem would it cause all sd cards to unmount? Or could it just effect 1?

I have a 32gb card that unmounts and remounts randomly. My 16gb card doesn't seem to have the problem.

Im not sure if the 32gb card is faulty or if it has a correctable error. So far formatting it does not help.

The difference between me and the op is that my card will mount, it will just unmount itself at a random later time.

[T-Mobile Samsung Galaxy S 4] Skipjacks:

[T-Mobile Samsung Galaxy S 4] crawler9:
Have you by any chance flashed a different kernel? I believe ExFAT file system is closed source and is not supported by most custom kernels, even if you're still running the stock ROM. If not, can you think of anything that you've changed between the last time you remember your card mounting and now?
[T-Mobile Samsung Galaxy S 4] DeadPlasmaCell:
Same here, plus viewing media on the card in the gallery seemed really laggy. I switched to a 16gb and have had no lag or issues with the card being mounted. The cards I got are both SanDisk Ultra cards

That is exactly the card i had a problem with. The sandisk 32gb ultra.

That narrows down the issue, doesn't it?!
[T-Mobile Samsung Galaxy S 4] imstill@g:
I just RMA'd a 64gb ultra for the same issue. I started researching....seems to be an issue with the latest Sandisk ultra. I pretty much went through the gauntlet trying to fix it.... Back to stock. Back to exFat, formatted with PC, Mac back to fat, either AOKP, or touchwiz. Same issue. At first it was fine. Then slowly started dismounting and remounting. Then refused to mount...worked around the issue by formatting in exFat, mounting in TWRP.and reformatting... This seemed to fix it for about an hour, I started downloading my music from Spotify...again with dismounting... Drove me crazy...ordered Samsung 64gb

[T-Mobile Samsung Galaxy S 4] carlsontheflyer:
My phone is completely stock and unrooted. It's an SGH-M919. I've had it for less than a week.

I too am having an issue with the SD card. I bought a brand new 32gb PNY card, class 10. At first it mounted fine and there was no problem. I transferred files to it from my old 16gb card that was in my Sensation for 2 years.

The following morning, after the phone slept and charged for the night, the card unmounted itself. There was an error message in the notification bar. I tried repeatedly to remount the card to no avail. I reinserted it a dozen times, rebooted the phone several times with pulling the battery, but the card wouldn't mount. I then tried the card in my wife's brand new S4 (we got both phones the same day) and the card didn't work in her phone either.

I then plugged the card into my laptop and it mounted just fine, and all data was still on it. I tried it in the phone again, but it didn't mount yet again. I even reformatted the card in my laptop, but it still didn't work in either of our 2 S4's.

I went back to Frys and exchanged the card for another PNY 32gb card. It mounted in the phone just fine, and again I transferred files to it. This morning, again after a night of charging the phone, the new card was unmounted with the same error message. However, when I woke the phone up, after a few minutes the card remounted itself without having to take it out and reinsert it.

So far it's been about 7 hours and the card has stayed mounted with no issues. We'll see what happens overnight again, when the phone is charging and sleeping.

On the other hand, my old 16gb card has stayed mounted in my wife's S4 with no problems for several days now.
