[Q] How's the I/O? - Nexus 7 (2013) Q&A

Has Asus improved the flash memory used in the new Nexus 7? How is the I/O?
This will be a major factor in others buying the tablet.

Yes they fixed it. Buy one.

It's a bit dangerous to make blanket statements like this when you actually have no idea whether this is the case or not, unless you'd like to provide some actual facts/figures to back it up.

How would you like us to test it. Its VASTLY faster than the old N7 no doubt.

The only way to really test this is the hard way. Install stuff until it's down to below 1g free then use it for a few days in a row without rebooting. Does stuff start slowing down, problems loading/wifi/scrolling at the same time, etc?

See anandtech review.
Android 4.3 uses fstrim, which helps with i/o speeds. Will even help the old n7

All.that has to be done is read Anandtech review. It has been fixed and a dramatic improvement over previous model. He has several benchmarks and test figures to back it up.

Yes, it will help. Various reports from original nexus7 owners said improvement was drastic. Anantech broke it down as to how the new feature in 4.3 works to achieve this. Its something called Ftrim, I believe. It cleans up and prevents device memory.from being bogged down after its loaded with apps and stuff. So users who updated to 4.3 on OG nexus7 are already seeing improvements. I will be updating both of my nexus7's soon to 4.3.

"Fstrim"
I was using it for the last couple of months on my OG N7 and it helped a lot. The app was called 'lagfix', it manually ran the fstrim utility that was present in android 4.2, but not yet implemented until 4.3

Thanks for.clarification. I've been away from n7 forums for a while. I.came back when I heard they were updating to 4.3. Sad to hear about team eos going a different direction on Roms. Can't wait to test out first hand how 4.3 improves my OG n7's.

I believe they no longer supporting team eos Rims or.the one at least on OG nexus7. I haven't read up on the details. But I heard they joined up with another group and going to take this rom or collaboration to a whole new level. Sounds like big things in the works now.for.them.
I.just recently flashed cleanrom 4.0 on my on n7. Its the first rom out with 4.3 build. I'm letting it settle for a while. As I have a million apps updating from playstore since I haven't used the device in over a month. But so far everything looking good. Can't wait to really dive Into it and see how she performs on 4.3. This might hold me off for a while on buying newer model. We will see. But I do want it though..lol I have my LG optimus G pro to satisfy my 1080P cravings for now.

I've only had my new Nexus 7 for about 7 hours, but can say it is VERY fast. I was downloading all my apps and did not suffer the SLOWNESS of my previous Asus devices (TF101 and TF300).
To early to say with absolute certainty, but do far it is FAST and SMOOTH. Oh, and the 1920x1200 display is something to behold

I can say the same! I downloaded 20 apps after updating my Nexus, and there was very minimal slowness. I am amazed with this baby!

It will be interesting to see the performance reports come in over the next few weeks...
Any videos that I've seen so far show the new N7 demonstrating noticeable lag. In fact the responsiveness seems on par with that of the 2012 model. Worse, in some videos, when compared to my current 2012 with CM and M-kernel.
Anyway, I'll be waiting for at least a month to see how things settle down (can't rely on just a few videos). As it stands now, for my needs and uses, the V2 doesn't seem worth it based on what I've seen...

Coming from Asus TF300T, which is incredibly, unbearably slow and laggy due to i/o problems, this was a huge concern for me.
Set and setting: I've been using it all day now, have 4 games installed and played, lots of facebook and chrome and youtube. My personal benchmark test is to open everything I use, use it for a few minutes, and then download something while browsing the internet and the facebook app.
Results: If my iPad 4 is 100% lag free, and my Nexus 4 is 88%, and the Asus TF300T is 0%, then the new Nexus 7 is about 75%. It's utterly nowhere near as horrible as the TF300T (which is unusably laggy), but not quite as lag-free as an iPad/iPhone or even a Nexus 4.
tl;dr not lag-free if iOS is the standard, but lag-free compared to previous Asus devices famous for having i/o problems.

Its noticeable coming from the OG N7.
Also the new N7 is supposedly faster then the N4 in all the benchmarks. I don't have an N4 but the benchmarks show a good distance gap between the 2.
This is my first non-tegra tablet and it feels wonderful.
Hopefully my Galaxy Nexus can get some benefit from 4.3. Its been horribly sluggish lately. Its a work phone with minimal apps. I'll try the lag fix on it.

I would think that a great way to find out whether its any better than the 1st gen N7 is to completely fill the new N7 up with a bunch of movies, magazines, music, etc. and see if it glitches out and lags. Thats how I would test it out first. But I don't have one yet.

Off topic, but there's an AOKP based ROM that helps phenomenally with the lag. I have yet to notice any while using it. Just my two pennies.

Getting back to the fstrim, does that mean that it's finally been implemented properly, and that apps like LagFix will no longer be necessary *in theory*?

Can the GN ever be as smooth as an iPhone 4S?

Alright, you're gonna be mad about the topic but I'm being honest here.
I never had a nexus phone and I was hoping that if I got a Galaxy Nexus, the phone wouldn't stutter (in browser and in apps) and it does. On websites the stuttering when scrolling is annoying. The phone is fast (home screen, app drawer, settings) but a lot of apps are jittery and not fluid.
I'm running AOKP Milestone 4 with Lean Kernel v2.4.
So my question is, is it possible to get the Galaxy Nexus to be as smooth as an iPhone? Some reasons would be good because there's no doubting the 4s is very fluid with rare if any hiccups.
Sent from my Galaxy Nexus using XDA
what apps...all mine are as smooth as the iphone.
AOKP is the king of extra features, but if you want smooth you should try Peter Alfonso's Bugless Beast.
The selling point if the iphone 4s is Suri.
My buddy tried to show it off and it didn't work at all.
He was really embarrassed.. It screwed up everything.
I showed him my nexus, and then I proceeded to pull 15 down 13 up in a speed test.
Boy was he jealous of my Nexus.
If all you care about is smooth scrolling, use the stock firmware. It's smoother than most ROMs, but lacks many features in the custom ROMs.
Don't forget, you're running a beta version of community created code. We don't have as much access to the hardware as the original designers, and can't optimize things as easily.
Whinging about it not being as smooth as an iPhone when you're running user created firmware is like complaining that the shelves you built yourself aren't as nice as the ones that your friend paid a professional carpenter to create.
AOKP runs great for most people, myself included, but there are tradeoffs for the extra features.
also, one more thing you gotta take into consideration is that aokp is more for customization. you want more of a rom that works only on stability. i havnt tried m4, but i do know that bamf is amazingly smooth. and alsooo when was the last time you saw the 4s? sure you can slide smoothly but doesnt it matter much more how quick you can load the page? try a diff browser also... mines working perfectly on google chrome and stock.

That's a poor analogy. The ROM devs are not building these ROMs from scratch, they are making relatively small changes to the code provided by Google. A better analogy would be assembling an office desk from IKEA (store that sells put-it-together-yourself furniture for you non-U.S. folk) vs having a carpenter friend put it together. Sure your friend might drill a hold here or there to make the fit better, but he isn't carving the shelf out of lumber.

stock browser and chrome are jerky but the stock browser is a little better

android will never be as smooth as the iphone, its running a dalvik client
Do iPhone users just get Android phones and swipe and down all day to see how fluid it moves. You guys know there is much more to the phone then just scrolling pages up and down, right?
You also realize the device is pushing a higher resolution then an iPhone as well so a lot more pixels are in play.
Seriously, even if the GN scrolled smoother then it already does, I don't think I would really give a sh.t......It would not change my experience in the least.

Project butter..

I've got a One X and a nexus 7, I'm running the same live wallpaper on both (flames) and on the N7 it is silky smooth yet on the One X it stutters every now and then... Now is this due to the so called project butter in jelly bean? Or could there be another reason?

the LAG thread --__--
Cleargrey said:
I don't know if this has been mentioned and I have only skipped through the thread and done a quick search, so forgive me if this has been spoken about already. The issue most people are facing is probably hardware. It's explained in depth on the Anandtech review, page 6 "NAND and WIFI performance".
http://www.anandtech.com/show/6073/the-google-nexus-7-review/6
Basically, the memory chips are low quality and can suffer badly when read/writing. I say badly, though not as badly as the TF700. This was explicitly the reason I didn't buy the Infinity because I couldn't justify spending that amount of cash on something so beautiful that is severely hampered by something that, for my uses, will hamper me quite a bit. So to put a good spin on it, the Nexus 7 costs less that half the price of the Infinity and has better read/write performance. And my G.Nex is better than both!
So the software/app changes are merely toning down a hardware issue. I'm not going to say "fault" because it was a cost choice by Asus and we know the Nexus 7 is relatively cheap. Why they made a similar choice in the Transformer line is beyond me.
Just turned off all updates for Currents. We'll see how it helps me.

Cool thanks for that. So all being said my HOX should be better than the n7 but it simply isn't. I love this phone but fear I have been excusing its flaws far too long. Time to get a replacement I think.

Since I also own a Nexus 7 and a One X, I ran two benchmarks, AnTuTu and Quadrant. The I/O performance in AnTuTu was almost the same, just like the other results. In Quadrant the results were completely different, the I/O score on the result on the One X was in the 9000 and on the Nexus 7 it was around 1900, almost 5 times lower. What to trust, we're do these huge differences come from? Is Quadrant not suited for Jelly Bean?

Well, it depends what you test. If you test sequential read, you'll get one characteristic, if you test 4KB random write, you'll get something very different.
I have a class 6 SD card that's 1000 times faster in iops (4KB random write) than another more expensive class 10 card from the same manufacturer. Of course, the other can sequential read about twice mine. The differences are more than surprising.
I have a galaxy nexus and, yes, it is smoother with JB. The one x will be smoother too, once it gets it.

Really? I'd agree about not really seeing the point of this thread but I still find Sense 4.1 pretty 'stuttery' (not actual overall performance, just the transitions) compared to AOSP - especially things like the way Sense doesn't always bother doing the app draw appearance animation, or only does about 5 frames of it. It's a shame really, given that I actually quite like using it, and I really miss the camera.
The funny thing is that when I first got the HOX I thought it was really fast relative to what came before and couldn't understand why you were complaining about Rosie not running smoothly and patching the launcher to flatten it out! It all depends on your point of reference, I suppose - and mine has changed since using AOSP 4.1 on this particular device.

yes it was a stuttery n no longer after the update, its not JB locked smooth on all fronts, transitions are 60fps just the few odd places where its not as smooth, n my point of reference is my native JB nexus 7
ur really willing to loose all functionality of sense including camera for the last 10% of smooth? and this is not sense fault, its an issue ICS as the entire android world knows already and hence JB's project butter

Actually, it is Sense. I was just trying one of the new CM9 builds out, and it's still markedly smoother scrolling around in the app draw, up and down settings, through home screens, around web pages, etc.
Unless you know of a Sense 4.1 ROM that's smoother than the latest Ordroid or ViperX? I suppose it is just a matter of getting used to it - as I said, it's purely cosmetic. I just really notice the micro-stutter and really inconsistent framerates when scrolling around. Actual app launches and most of the functionality are actually faster in an hTC-based ICS ROM than in JB...
All using faux123's latest, obviously
OK, i agree that on the begining HTC make a "Half X" and it was everything but not smooth ... but what are you guys want now? I mean, fo what are you guys using your phone, scrolling the whole day thrue the appdrawer and if it stutters going straight to xda and crying over HTC?
If you ask me, i have a great phone now that can handle every app and game out there

Yep, If you do anything on the nexus 7 that involves accessing the memory it will slow down. I really dislike the n7 because of this but the price is still reasonable for what you're getting. It's my comic book reader, movie viewer so I don't mind if it lags doing other stuff.

Yup someone just posted a lag fix for the nexus 7
http://forum.xda-developers.com/showthread.php?t=1875712

[Q] Is my phone slowly deteriorating? (terrible performance)

Hello whoever is reading this,
I'm getting real tired of how slow my phone has consistently been slow for months now. I've tried a bunch of roms and kernels in combination, and while it seems to work smoothly after a clean flash, it slows back down to its usual laggy state within a few days (or even hours!)
I partially blame the age of the phone, as it's old processor probably can't handle all of the customizations being thrown at it that are really being developed for the Nexus 4. But aside from that, everyone in every rom or kernel thread is always raving about how "buttery smooth" or "lightning fast", or whatever else their phone is, claiming performance is awesome. It could just be that all those users are just used to some lag, but I'm really starting to feel like I'm the only one who has such performance issues.
For this reason I'm wondering if it's possible that something hardware-wise might be starting to die, similar to how "cheap memory is killing off Google Nexus 7". Is this possible?
Is there any app that can run hardware tests to check for things like that? I would love to see if my suspicions are correct or totally wrong. Is there anything else I should try?
I'm currently running the latest ak47 rom (AOKP Milestone 2 on top of VANIR (linaro), and using Fancy Kernel. I've found the performance is pretty good compared to other roms I've tried but I still find myself waiting seconds for the app drawer to open, to scroll through pages in the app drawer, etc.
Any help would be much appreciated. Thanks.
Hmmm... if it is anything related to what was happening with the Nexus 7, then you've probably heard what Android 4.3 did for it. I'm writing this from my Galaxy Nexus, and it hasn't been faster since 4.1; whatever 4.3 did for the Nexus 7 has a similar effect on my GNexus. It took a couple days, but I have my butter back!
Before the update, I was in the same boat as you. Even the keyboard was ridiculously laggy. Now? Buttery. Not Nexus 4 buttery, but buttery.

I didn't hear what 4.3 did, but I gather that it improved the speed? Sweet, maybe I'll try that. My issue is I'm too addicted to AOKP
But I'll have to try a stock 4.3 rom or something and hopefully I'll find the same results as you. Thanks for your input!
My question about an app that runs hardware integrity tests still stands.

No problem! And it provided a lot of behind-the-scenes improvements for graphics processing. It also made FSTRIM turned on by default in the system; it will run whenever the battery is above ~70% and the device is idle. It basically stops the device from needing to perform multiple actions in the storage whenever it needs to read or write. You only notice the effects of it NOT being present over many write cycles, which is why performance may seem to have deteriorated over time.
And yeah, custom just gives you so many choices! But a few days with 4.3 should REALLY ramp up your performance. It takes a little while for FSTRIM to do it's magic. App drawer opens after 0.7 seconds or so, and swiping between pages is quite fluid and responsive.
Glad to be of service! Hope it helps out.

Aside from 4.3, I've found that if you goto Developer options, and lower the Transition, Window, and Animator scales from 1x down to .5x things seem to move more smoothly. Albeit they only reduce animation times, the visual effect may be enough. I also use Nova Prime launcher and turn animations to "Nova" speed. Things like the app drawer open instantly. Absolutely zero lag. What I'm running is in my sig...

Hello whoever is reading this,
I'm getting real tired of how slow my phone has consistently been slow for months now. I've tried a bunch of roms and kernels in combination, and while it seems to work smoothly after a clean flash, it slows back down to its usual laggy state within a few days (or even hours!)

Any help would be much appreciated. Thanks.

This frustrated me for a long time until I came across this app (root needed):
LagFix Free: https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix&hl=en
XDA thread: http://forum.xda-developers.com/showthread.php?t=2104326#fm
"Some Android users suffer from poor performance after some days/weeks of heavy usage. This is due to a well-known TRIM bug affecting these devices. The source of the problem is that internal storage is not properly TRIMmed when needed. It is also well-known fact that running fstrim Linux tool from time to time fixes the issue until internal memory runs out of free blocks. LagFix is a user-friendly implementation of fstrim utility. It allows you to select which partitions to trim (you should leave defaults unless you know what you are doing) and run the process easily."
Android 4.3 finally implements this fix, so if you go a 4.3 ROM, you won't need this.
Yep, like they all said, 4.3 fixes that with things like TRIM, and I can attest to that firsthand.

I must say that the phone is faster on 4.3, but my battery life is horrible when comparing to 4.1.1 or even 4.2.2, especially when using the phone.
I don't know if it's true or I'm too bugged about it. Could someone please confirm it to me?

I guess it's just bad luck haha.
Gonna test it calmly to be sure.

[Q] Nexus 7 lag/stutters

I have owned my nexus 7 2013 for about a week now and i am thinking of returning it due to the lag/stuttering i am experiencing on it. I started noticing it when i flashed lollipop on it, i went back to kitkat 4.4.4 and thing's were certainly improved but i thought i would do a comparison against my moto g 1st gen and i was surprised to see my moto handled thing's better, app opening/closing animations are a hell of a lot smoother and game play is smoother too.
Is this normal behaviour i am experiencing or did i mess something up when i flashed lollipop using wugfresh toolkit? I also rooted it and flashed a custom kernel but after an hour or so i went back to stock, i even went as far as flashing 4.3 then updating back to 4.4.4 through my tablet and done a few factory resets but no difference.
Are you completely stock? Stock kernel and everything?

Yes currently everything is stock
I am also experiencing the same issues on lollipop. I might have to do a completely fresh install. May be, it's just our devices showing their age. I don't want it to go the Nexus 7 2012 route!
Nah man, I installed DJ's 5.0 build and I am getting much better performance and battery life than KitKat. I also have Elemental kernel installed, smooth as silk.

I actually did do a fresh install of lollipop. I went back to kitkat hoping the lag will be fixed but it's still here a little although it is improved.
It's a shame i didn't get the nexus 7 2013 when it 1st came out, maybe with all the newer processors out the nexus 7 is showing it's age. I still find it weird that my moto g runs smoother although that could be down to the lower res screen.

Did you try it on stock rom/kernel? I actually flashed elementalx when i went back to 4.4.4 and i kept it at default settings but noticed some frame drops on temple run 2 so i completely unrooted and took everything back to stock but it's still the same.

It's showing its age a bit definitely also it's an adreno 320 pushing a 1200p resolution, and that GPU was really designed with 720p in mind. That being said while I definitely can tell a difference between my nexus 5 and nexus 7, the nexus 7 has aged very well and still enjoyable to use unlike my HTC flyer and original nexus 7 that both aged very quickly and became a burden to use within months
I got mine last Christmas so I never used 4.3 on it. I was rocking a nexus 4 at the time and it was noticeably faster than it was. As far as lollipop goes seems the same. Think it might depend on what apps you use, as a lot and I mean a lot of apps aren't optimized for lollipop yet.

I replaced it with a galaxy tab pro 8.4, it's around the same price and the hardware is better than the nexus 7 so hopefully it will be a little more future proof

New N5X seems slow

So i have just upgraded from the Nexus 5 and very happy with most things, but the screen seems very slow to respond. The phone is obviously faster and runs very well, but just scrolling up and down lists, it seems like there is a lag between my finger and the picture. Is this normal? It feels like even the Nexus 5 is much more responsive.
I read a few bits about encryption slowing phones down if its not hardware supported. I had intended on disabling the encryption when i got it but soon found it that there is no easy way to do so. Whats the best procedure to do this and would it make any difference?
Thanks.
I had issue with lag, and even had Google send out a replacement because I thought I had a defective phone. It was unbearably slow, especially when using the camera. I finally broke down and rooted my phone and disabled the encryption. It is a night and day difference! I'm kicking myself for waiting so long. There is an all-in-one tool in the original development thread I used and then installed the Pure Nexus rom.

Thinking lag is a hit and miss because mine didn't lag at all un-rooted and encrypted. Granted that was only like 12 hours of being at work, so an hour usage.
I haven't had any lag on stock encrypted, I have had this phone for 3 weeks, and runs quick and responsive for me

What do you mean encrypted?
I am getting this phone tomorrow, I want to make the best out of it. Do I root it or do I use stock?

This device comes with its user storage encrypted out of the box, that way no one can obtain access to your files if you were to lose it. For example the FBI is trying to force Apple to decrypt an iphone for them right now which is bringing a lot of attention to the subject.
Anandtech has shown encryption can lower the storage speeds by about 30% on the 5x versus the LG G4 which uses the exact same NAND. However even at 30% reduced speed the NAND is still considerably faster than both the Nexus 6 and Nexus 5 and theoretically shouldn't cause any issues.
I have no slow downs with my device BTW, it is stock, not rooted, and encrypted as it was coming out of the box.

^^ What he said. And definitely root and flash a custom ROM and kernel. Otherwise you'll be missing out on much of the glory there is in owning a Nexus device. You'll also have more customization options and things should be a bit faster as well.

I have the phone, its dope atm. It's also fast as heck!
I love the fingerprint scanner, so beautiful!

Before you get settled in, I suggest you try different ROMS until you find one you like. Some are chock full of features, some are more performance minded. Depends on your tastes. I'm currently running Ubermallow ROM, which is in my signature. As for kernels, it's the same story. All have different features and abilities but I'm running Phasma Kernel which focuses on performance.
Experiment. That's the beauty of a Nexus device. There's something for everyone.
