I'm curious... Do you apply/wanna apply a lag fix because your device is actually lagging or is it just the thing to do nowadays? I ask because I have never found a need for one. The only lag I had on the Vibrant was when I first took it out of the box and even that was kinda tolerable. But as things are right now, I really don't see how my device could get any faster and if it could...why? Quadrant scores? What is the real advantage (if any) to having it? .02¢
Lag fix? Never have, never will!
High quadrant scores. Do you see the first thing most people mention when they install the lag fix?
"My quadrant score went from 200 to 2000!!!!!!!!" as if it was an indicator of actual performance.
No good, controlled tests have been conducted.
I don't use it. The one time I did, when it was included in the kernel with BLN, I had horrible battery life. Most people use it to get higher scores. The N1 would run circles around the Vibrant in terms of scores but when in real world testing, both devices are just as fast.
It's not just scores...
It makes your system a bit faster people nowadays do it without needing to and there's nothing wrong with that.
I run a lagfix and it has improved my speed and response.
Without making me lose any battery

Point taken, but looking at most of the threads in the Q&A section...it seems that the LF's do more harm than good, especially if you aren't too sure about what you're doing.
Lag fix? Never have, never will!
The lag fix circumvents RFS in many areas.
Galaxy S phones have terrible I/O performance. Notably Database Read/Writes and apps that work generally hit the storage often.
Run Touchdown on a Galaxy S phone without a lag fix and you'll see how sluggish that application runs due to RFS. The workaround is to move the database to the external SD Card (which results in frequent corruptions) or install a lag fix.
It also causes the phone to take an inordinate amount of time to boot up (Media Scanning... etc.) and lag randomly when applications sync and access the storage to write data. It lags when Installing and Uninstalling applications from the Android market as well.
If you think a Lag Fix is only to boost Quadrant Scores (those scores are bunk, anyways), then perhaps you're using a different phone in a Vibrant casing.
There are several applications littered with "laggy on my Galaxy S" in the market.
Also, there is a bug in the Samsung Android 2.1 kernel that breaks some applications. That's why there are apps popping up saying you need 2.2 on your Galaxy S phone to run them (Skype, Yahoo Messenger, etc.).
My Vibrant, both before and after JI6, was laggy to the point of not being usable - until I applied RyanZA's OCLF (I removed OCLF and tried voodoo but soft-bricked the phone in the process). I've never run the Quadrant score analysis - all I care about is usability of the phone, and after the OCLF was applied my phone became usable.
I tried Axura 2.0.x with no lag fixes and, while my phone was generally faster than JI6 pre-lag fix, it still suffered from lag in many user interactions (opening apps, launching email, reading individual emails, using gallery, etc.) I went back to stock + JI6 via ODIN, reapplied OCLF, and was happy again.
Are there different hardware revisions of the Vibrant that might account for the differences in user experience? I've seen many posts from users who claim they never had any lag or GPS problems, and many more (like me) who have been plagued with them.
Most of those users are fanboys and wouldn't admit it even if they fot one of those 5+ second lockups while making their post.

It's cause the phone is laggy. I don't usr lag fixes because I don't lile tampering with phones at the system level, regardless, but I have freezes several times a day and have even had my phone completely lock up on me a couple of times - requiring a battery pull.
The less services you have running, and the less apps that sync data runnimg, the less the lag is. The lag happens mostly when the storagr is used (background syncing can cause it, for example).
Yes, people with no twit/fb/reader apps/accounts setup, among other things may be totally fine depending on their usage.

It has made some apps actually usable.
Before the lag fix, the facebook app was basically unusable for me. Any action would have a 5-10 second pause before seeing a result.
Swipe to scroll, wait, click a picture, wait.
I think the facebook app was the worse for me because I did manual updates so every time I launched the app, it would be d/ling and writing while I was trying to scroll around and read stuff.
But in general, it has made my phone usable. Before I did the lag fix, I basically stopped using my phone because it got so annoying having to wait.
I've never run quadrant on my phone actually. I don't even really use root for anything. I did it primarily for the lag fix and the I changed my battery bar so that it's accurate. Everything else I'm happy with.
So, could this just be an issue that only certain phones have? Or, could some of it be mental? Like, if you hear enough ppl say that this is broken or that isn't working...you start to think that yours is broken also? I've never had an issue with gps...and I use foursquare and navigation on a regular basis. But everybody else seems to have broken gps.

This makes sense. Everything besides my work email account is synced manually. FB, TD, etc. And when I get really busy I even cut my data off. But on the other hand, I text and browse constantly. And switch back and forth between appear running simultaneously. And when im not working...

hmm... I used a JFS lag fix for awhile, and it still hung slightly when syncing.
it did not seem better or worse really.
and the same thing happens on my mytouch so I think its just something that happens, lag fix running or not.
its really not that bothersome, but I do the same as you, I manually sync most everything.
I mean if I'm not looking at my facebook widget constantly, why should it be auto syncing?
lol it only takes a second to push the refresh button
but thats just me.

I have 2 email account, syncmypix, weather apps & news updating every hour and i have never had any lag problems, even running on JI2 stock, much less ever had phone freezes. The ONLY time I had phone freezing was messing with those OC kernels, which I promptly uninstalled.
Let me ask people that run lag fixes this, when playing with the Vibrant at the t-mobile store, why did you choose buy it if you were experiencing this "lag", especially when it was running stock firmware?
edit: I also ran JFS lag fix for a day, but that drained my battery faster than a fat kid ate cake. It was not even noticeably faster either.

Its not mental its on every phone. Unless lagfixed/hacked u have the same fileaystem as us.
The home switchers and unofficial roms are morw mental due to placebo effect - some lag fixes aren't even that good, but people claim tenfold improvements due to placebo effect...

The phone T the store wasn't syncing a google and corp accoumt, plus facebook, plus twitter, and other apps. It simply wadn't prone to lagging, brcausr no user in their righy mind sets their **** up on a display unit just to test it.
Btw, "why didn't you test it for 10 min before you bought it" is getting old.
Their were no other good phones in t-mo when many of us broughy yhis. Couldn't just swap for a g2, mt4g, or hd7.
Many people thought an update would fix it, like the gps.
We were wrong, obviously.

If not syncing, then you can miss direct message notifications on fb and twitter.
Symcing manually is unacceptable to many. Don't have to do that on other phones......

If you have stock rom then oclf is best and I'm on Axura so my choice is voodoo but I've read it causes too many problems.
People should know what their doing before messing with stuff like that..
They have a forum here to ask all these questions but they do it themselves then when their phones screwed they ask questions...

I've done it on pretty much every phone I've owned, but like I said its not really nessicary, if anything its a slight stutter, but either way its not different than other android phones I've used (even my vibrant using a lag fix). its really just my preference to sync manually.
Gentlemen and ladies,
I am opening this thread for constructive feedback of the TFP in real world use after the .28 update. Please stay on topic, HELPFUL and RESPECTFUL. By having an open an honest forum, we can help drive development and troubleshooting. Please be thoughtful and give it some time so you get a good sense of the changes.
My review will be here sometime this week and I will update regularly.
First two hours:
General feeling is that it's is considerably faster and smoother. Swype actually functions like it should with no lag, which is huge for me. Wifi signal is stronger, went to the opposite side of the house which is through a brick wall , a refrigerator, and another wall, about 30 feet in total. Used to get 1 bar, now a solid 2, total signal loss of 36% on wifi analytics app. I did get two ANRs on Facebook using dolphin, got it on stock browser too. had this scenario twice so far: 2ANRoD, two ANR of death, on stock browser with flash heavy objects, I'll get two popups and wait doesn't fix it and browser crashed. Still Pleased so far. More to come.
After first full day (6/14/2012):
The happiness with the update is starting to fade a bit as some old problems remain. I cold rebooted to see if there was any improvement, (not really)
Browsing: I have been experiencing a few ANRs messages consistently, they are way less than .21, but a few time an hour. I have noticed that google news website no longer produces the ANR on dolphin, where previously it did. Some sites that are flash work great, others not so much. FB webpage creates the ANR message everytime. I do continue to get some hangs or web pages that do not load completely, but generally the experience is faster loading. Stock browser continues to perform better than Dolphin, so I have to switch back and forth a bit which is annoying. .28 is still a step in the right direction by clearly not up to par. From Gary's post, I look forward to the next update to clear this up.
Productivity: opening pdf files is noticeably faster but still EXTREMELY slow by comparison to my sgsII. (For example, my sgsII opens a 3mb pdf of 180 pages in less than a second, whereas the TFP takes at least 10 seconds or longer to load a 3mb file of 10 pages.) I find this to be unacceptable as I bought the TFP specifically for work related tasks. using swype is still better, some glitchiness but far less.
WiFi: still better than .21 consistently in my home. Signal has been noticeably improved. I am definitely pleased there.
UI: Definitely there is a sense of more smoothness and snappiness most of the time. The TFP is pretty tempermental at times with increased lag, slow downs, or out and out unresponsiveness for 10s or greater. Sometimes its perfectly fine with no rhyme or reason. Definitely an annoyance when this occurs.
Battery life: I haven't notice a huge difference yet, but my use patterns are typically 2-3hrs so i don't stress the battery too much, i do have a vacation coming up so we'll see then. I do notice on the that when the dock is plugged in, it transfers battery to the tablet sooner. A few weeks ago i had a class for 9 hours, i noticed the tab would discharge to almost 50% before the dock kicked in. Now, the dock kicks in right away. after about 30 minutes i'm down to 80%, as it charged the tab about 15% then seemed to stop charging it for a while. looking at the battery meter i notice that it made a small sine wave, kicks in a little, then lets the tab discharge a bit. cool. ps- can i request a better battery graph? maybe some numbers and xy lines?
24 hour impression: This update is a step in the right direction as there are some improvements, but those improvements by an large are hard to quantify, other than the WiFi. I believe that the website loading is better most of the time. I am definitely disappointed by the ANRs and processing; my belief is that there should be improved processing over my sgsII dual core. I'll say this now because it came to mind over the last 24 hours: though less than .21, erratic performance and continued problems nearly 7 months out from release, with an update that took a long time to come out makes me suspicious of larger issues. I believe that there are solutions, and .28 shows that things can be better, I begin to wonder how much of a time investment will make in the tf201 over the long run to get it to where it should be. Over the weekend I am going to be using the dock and probably playing more games, so I will round out my review at the five day mark.
Wifi/BT on the new firmware I am actually seeing an improvement now. I used to get about 1-2mb when using my headphones out of 20M. Now I'm seeing about 3-5.. so they messed with something good thankfully. It seems Netflix doesn't buffer for me as long as I'm getting 1-2mb down so I'll take anything better than it was
Browser was not an issue with ANR for me before but seems fine as well after the update I set my plugins to ondemand in Advanced settings. No wait messages yet
give it time to settle in though. people can't say update is really bad and haven't even ran it for more than an hour yet..lol just saying.
constructive criticism always good. ill vote.
for me, running this update over 2 weeks now, its been running great. battery life improved alot. wifi performance better(for me). no browser ANR or crash in 2 weeks. most graphic heavy games playable now without crashing. overall faster feeling device. no random reboots. I like this build way better than. 21..lmfao
No ANR messages so far (although I've only had the update for a half an hour or so). On 0.21 I would get the wait popup on a regular basis while using the stock browser and other apps such as Engadget. Things seem snappier overall but I think that may be primarily due to the absence of the ANR popup.
Its actually a little weird now, I got so used to reaching towards the screen to cancel the ANR popup and now I don't have to do that at all, I can just keep my hands on the keyboard/trackpad.
Wifi Direct seems to work, lets me connect to my Nexus now, but after its connected though not sure what I can do with it. I looked in File Manager for it but not sure where it would be
Super happy thus far......
went from......
GPS.....V6.9.16 to.......V6.9.20
Bluetooth....V9.27 to......V6.9.29
Wifi....V6.1.1.22 to...........V6.1.1.24

Troll much? I mean seriously this is your first post.
Been using the update for about 2 hours. Had one ANR while setting up face unlock, but since then it has been phenomenal. All games play now, couldn't play shadowgun, riptide or dead space before. Web browsing is incredibly smooth. Haven't done wifi tests yet, but I can tell that it has improved. Very happy with the update.
Face unlock is stupid....
Suprisingly wifi has improved for me too.
I tested right before the ota on a fresh boot and right after in the same spot
Averages Before (On a 18mbit up/down connection):
Download: 2mbps
Upload: 3mbps
After:
Download: 5mbps
Upload: 7mbps
I am VERY happy with this ota.
Download went well, but I could tell that there was major upgrade in firmware just when putting in my password. WiFi is much better, website pop open. The web moves faster then on mine laptop. I like it! Please do make sure to reboot or do a soft reboot before running with it, you will notice the difference.

Really glad you signed up, for that single post!
I just want to say that it's nice to see that Asus, in spite of the fact that they've since released the TF300 and will soon be releasing the Prime Infinity, are still working to improve the Transformer Prime, and haven't given up on it!
I, for one, appreciate their efforts!
My Prime has been very stable before the update, and I've had no complaints about wifi. I don't really use GPS on my Prime, using my car's GPS and my Thunderbolt much more often.
The one issue I have is the task manager will on occasion give me a "Task Manager has Quit" message, or something to that effect. Hopefully, that'll be resolved, but again, it only happens maybe once every three, four days.
I do like the face unlock feature, and the ability to show stats after locking the status bar at the bottom is a nice touch, if slightly unnecessary. My battery life has never been a problem, as I generally have over 40% in the evening, even after heavy use. I always charge it when I go to sleep.
I do hope that this update solves issues that I realize other people have been having.

yeah, Asus task manager has been buggy since the beginning. it looks like they trying to improve it though. or at least its looks..lol
Installed update, rebooted after the first boot, as mentioned a couple of times. Restored root with Rootkeeper. Had 2 ANR in the space of one minute while trying to load www.hotnews.ro (the desktop version). Chrome doesn't seem to do ANRs, although it also froze for 1-2 seconds a couple of times (and is also definitely more sluggish than the stock browser during page load).
Doing stuff during market updates is much less irritating now, seems to move better overall.
Will keep testing.

I just tried that site you mentioned. it loaded up fine for me with no problem. no ANR. cool looking news site. too bad I don't understand that language
Can we keep root with OTA root keeper?
Yes we can. Just restored root about two minutes ago.

I am seeing alot of ANRs with the facebook app. Specifically, it occurs more often and responses slower the further down I scroll; until it reaches a point where the app will no longer respond even after waiting a while. G+ on the other hand seems to be smoother.
I have gotten 1 ANR with chrome, but after waiting it started responding again.

It pisses me off to see me and many others complain about such a basic thing as LAG in this "super powerful" device.
What is the point of all this tons of CPU, huge RAM and etc., if it cannot manage basic tasks quickly. that's great that i can play 3D games, but I want my phone to be responsive as it used to be in the beginning.
How come I need to wait for 5 seconds for my contact list to load? 3 seconds for my SMS to load, 2 seconds for an app to load in the application center. 1.5 second until it responds to a home button. You expect this kind of basic tasks to be done INSTANTLY.
So what if I have lots of contacts? Doesn't Android follow BASIC programming concepts?
That is first load the frame, then show LOADING, then load the most necessary (in that case would be the first part of the list) and then load the rest. This way it doesn't feel laggy for the user. How come it simply loads for 5 seconds without any response and then shows ALL at once.
Everything is laggy, almost anything I press takes 1-2 seconds to respond the first time. Second time is mostly instant.
Tried to clean cache of all apps, using memory cleaners, disable double home click, I am at version 4.3, using Go Launcher.
How can I find if there's a specific app that causing it? Or what should I clean to make it go smooth as it used to be when it was new? all these task managers and such don't make ANY difference. Total waste of time.
Don't mind me being pissed and thank you for your input
P.S. - My device is not rooted.
yeah....that's why i put my S4 aside and bought the G2. it's touchwiz. it's horribly optimized and has been since JB. on ICS, touchwiz was great. it was snappy, fast, awesome. it was amazing on my S3. then the S3 got JB, and it turned to utter garbage. now, every samsung phone since JB is awful.
they really need to scrap TW and code it all over again.
I'm not getting this 5 second lag. 1 and a half seconds perhaps on the contact list and I have maybe 210 people on there.
If you're getting 5 seconds of lag I think something's up. I'm getting pretty quick responses WITH Power-Saving Mode enabled. With it disabled I don't really notice anything different tbh lol.
Sorry you're having a pain of a time. If you're going to get a new phone I would suggest the Nexus 5 :laugh:
I'm stock non-rooted.
Nova Launcher
That's it.

Nah, I'm not gonna get a new phone just because of that.
Could you perhaps tell me with which accounts you sync your contact list? I would assume that's related. Also are you trying it after your has been idle for a while? (it's much more responsive when I open it the second time)
Because of all the bloat you have installed...take off go launcher lol
Sent from my SCH-I545 using xda app-developers app
Go launcher is the worst. Go to the dev settings and change animation time to 0.5x or off, get apex or nova and use the fastest animation speeds, try different dialer & messaging apps. Don't use memory cleaners or task managers just delete whatever apps you don't use. Basically avoid using as much touchwiz crap as possible lol. Also know that live wallpaper and a lot of widgets cash slow things down too. I would think keeping all the stupid proximity sensor stuff on doesn't help either.

It really does suck how slow this phone is considering it's hardware. Samsung needs to hire some new people because my girlfriend's htc one is very smooth and snappy with almost no lag (minus att 's slow 4g network) I wish htc would pull their heads out of their a**es and build good phones with good cameras with removable batteries and sd cards :banghead:

If you go through and disable stuff like crazy it improves, but that doesn't really speak well for Samsung.

I'm using nova prime as well as quite a few xposed mods including XuiMod.
All my nova settings are at faster than light, XuiMod settings are also set to fast, and I've set the transition animation scales to 0 /. 5 as well.
My S4 flies. I have no complaints at all. I've used titanium and gotten rid of all the BS too.
I agree TW has a lot going on but can be set up quite good and run quite fast. I've looked at other phones over and over again, trying to get back into flashing ROMs, but I keep landing back at my S4. It's still an awesome phone
Verizon Galaxy S4

ALL Knoxed Up!
Don't mistaken transition speed for loading/processing speed which are two totally different things. The S4 is no slouch, if it's "lagging" like you said, it's an app for sure. I nor anyone I know with an S4 has experienced this phantom lag. But then again we don't blow up our phone with launchers, widgets, or 5 different apps telling me my battery level and apps running. Try using stock everything (launchers, dialers*lol*, messaging*lol*)

So what if I have lots of contacts? Doesn't Android follow BASIC programming concepts?
That is first load the frame, then show LOADING, then load the most necessary (in that case would be the first part of the list) and then load the rest. This way it doesn't feel laggy for the user. How come it simply loads for 5 seconds without any response and then shows ALL at once.
Everything is laggy, almost anything I press takes 1-2 seconds to respond the first time. Second time is mostly instant.
Tried to clean cache of all apps, using memory cleaners, disable double home click, I am at version 4.3, using Go Launcher.
How can I find if there's a specific app that causing it? Or what should I clean to make it go smooth as it used to be when it was new? all these task managers and such don't make ANY difference. Total waste of time.
Don't mind me being pissed and thank you for your input
P.S. - My device is not rooted.

whatever61, did your phone behave like you have explained (lag) when you first bought it? If the answer is no then you have an apps/widgets/or other software on the phone causing you the problem. The ole' saying 'keep it simple stupid' kind of applies here (not saying at all that you are stupid). There are only so many resources in our phones...cpu capabilities, memory etc. The resources in our S4s are pretty significant considering the size and the limited power available. It really boils down to this...the more task you demand your phone to perform the more resources it uses and at some point it has to slow down to reallocate the limited resources it has...lag. Task managers use more resources than they save...live wallpaper is a resource hog...widgets (weather, facebook, goggle now, goggle +, pandora etc) constantly updating and running are resource hogs...contracts with added thumbnails, although "neat", take up not only memory but take longer (resources) to process when you want to look at one (when you call up a contact do you want the information or do you want to look at a picture, which one of those do you NEED?)...email and messaging apps that have to sync more than a few days of old mail/messages is a waste time and resources...Samsung has put a lot of "cute" animations and gesture sensitive "crap" on our phones...they are "cute" but not necessary and use resources. Bottom line...do a factory reset, decide what you need and "keep it simple stupid". (Again, I'm not calling you stupid!!).
Don't worry, I didn't think you are calling me stupid
Yes, if I remember correctly in the beginning it was working faster (but cannot say for sure what and where was the lag already existing and where it wasn't) and what you're saying about widgets, lots of apps and all that is very obvious and very general (thanks for the input, though). The don't install too many apps or reset to factory approach is not something I think a correct approach. I bought a super powerful phone to be able to install whatever I want on it, right?
Besides an example that I provide is that when I am in the application manager and pressing on an application it takes like 2 seconds to open up. I don't think it's related to me having too many apps.
I think that I should be able to see which app is causing the lag in each case and then make my decision based on it. Yes, I can install different task managers to show me which app is taking how much CPU and RAM, but I don't see anything exceptional there. Problem is at specific actions I do, so it would be good to see what happens (like in Chrome inspect element) when I press on the action, which processes are being launched, how much time it takes for them to complete and how much CPU was used at each process. A log like that would do the job.
Besides my post was more about the wrong engineering (see the example of the Contact list lag) and the fact that many people complain about the lag in S4 and a question if someone knows about a tool that can help me find what is causing the lag (see description of the tool above).
Thanks

Don't mistaken transition speed for loading/processing speed which are two totally different things. The S4 is no slouch, if it's "lagging" like you said, it's an app for sure. I nor anyone I know with an S4 has experienced this phantom lag. But then again we don't blow up our phone with launchers, widgets, or 5 different apps telling me my battery level and apps running. Try using stock everything (launchers, dialers*lol*, messaging*lol*)

I don't like "stock everything", besides seems to me like stock stuff is even more laggy.
I don't blow up my phone with stuff neither and I think the reason lies in something else (see my post above for a better explanation)

I understand your frustration and your point is well taken. I don't know of a utility/app that will enable you to clearly identify an app or process that is causing the lag you experience. I know doing a Factory Reset is a big PITA and I never recommend that to someone unless I know of no other "cure" for the problem. And, sometimes a Factory Reset isn't the cure either. But often it is. The reason I recommended Factory Reset is that it is about the only way you can (that I know of) start with a "clean" phone and nail down the app or apps that are causing a problem as you reinstall them one or two at a time. I have a developer edition S4, rooted and bootloader unlocked, and I usually will do a factory reset every two or three weeks even while running a ROM that has been debloated and "fine tuned". It usually improves battery life and the phone works smoother...or maybe it's just my imagination, but I don't think so. Anyway, good luck, hope you find the problem. Maybe some wise ole' guy will come along and point you in the right direction.

Well, for the most reliable experience, it is always best to stick with stock.
My advice is to run stock everything for a day to see if that's the problem. Your other option would be a factory reset in which I am trying to make you avoid.
Do you have 3rd party apps installed like sms/launcher/dialer/lockscreen/etc.? I can't imagine the amount of processes going on if someone had all those apps installed.

I really dont understand why people complain about this so called lag. I've had no such thing since I got my s4 right when they came out.
My girlfriend gets her S4 acting all strange sometimes too, can seem laggy. However she is constantly downloading music and she uses like 3 programs to do so. I've had to remove quite a few of those apps and then it's working like new again. Sometimes a lot of the apps available out there just aren't the best and can screw things right up I think. I've had none of the issues she's had. Mine has been fast as hell since day one. And hers is back to normal too, I just have to keep an eye on her!!

This post is ancient, but I still got the problem
I am just curious if other S4 users have the same problem or most don't ?
Then I will know that something is possible to do for sure, at least..
So, after 8 months of use, my M8 is finally in a situation where I'm kind of sick of it running so poorly. In the past I've always had these issues over time, but I always contributed it mainly to running custom ROM's. Well, when I got my M8, it ran so well I decided to leave it stock. Well it's finally starting to hit a wall and it's more of a frustration than a joy to use. Swype is borderline impossible to use since it lags so bad, freezes are infrequent but occur, etc etc.
So my question is, what are the most likely contributors? Apps that run in the background? Too many apps? Too much space used? I can't think of much else, since, like I said, it's still fully stock. Or is this just what I have to expect from a phone?
Do you clear the cache in your app settings. If you game a lot than I would definitely start with the game apps first.

I kept my phone stock for quite some time because I felt I didn't need to change anything, until last week because I was tired of radio issues. Bottom line, ATT sucks at getting updates out, so if your running stock, your firmware is like three updates back. I see a massive improvements in speed and battery with 3.28.1540.5. If you know how, I would S-OFF and upgrade firmware to that and flash the debloated custom stock Rom that comes with root and SU. There are straight forward instructions in the att m8 development thread.

I might look into this. What I don't get though.. I can understand if new updates are quicker. That makes sense. What doesn't, is how ridiculously poor my phone runs compared to the first few months I had it. It's been like this for every phone I've had. I don't game, I don't have all that many apps. In my running app list, the only self installed things there are Facebook and Swype. I have plenty of extra storage internal and on my SD. So what is it that causes such poor performance over time? I'll definitely have to check out the newer roms and finally s-off.. but I've done plenty of custom roms before with other phones and the same thing always happens, things run fine for a bit and then slowly go to crap.

Its hard to say what is causing your issue, and aside from saying Swype is lagging (might be an issue with that app itself) and the phone "doesn't run so great anymore" you really haven't provided any specifics of what the problem is. You also haven't indicated if you tried to clear cached as jball suggested, and if so, if it helped at all.
Might be some runaway (poorly coded) AT&T bloat apps. But in general, apps running in the background will not slow the system down much. There are various apps to track battery and memory usage, so you might try one of those, to determine if any particular apps are the culprit.
I can't say I've seen any lag on my M8, but I switch ROMs fairly occasionally, and keep it updated to current Android builds (thanks to s-off). Clearing up your data partition alone might help (but might now, on the other hand) so you might also consider backing up any personal data and doing a factory reset. Wiping the slate clean might solve your issue.
Ok.. well a lot info there but one step at a time. I realized my phone is Sunday unusable with Wi-Fi turned on.. which is quite interesting and I'm pretty lost on this one. With Wi-Fi on, it's like my entire phone stops, not just the actual internet speeds. Apps like Facebook take ten seconds just to load, and then the actual content takes sometimes 15 seconds to load or maybe not even at all. Also, keep in mind, my actual internet speeds are fine, and even test perfectly fine on my phone.
As soon as I turn off Wi-Fi, it seems everything on my phone I'd dramatically quicker and everything loads near immediate. I've tried restarting my phone, cycling airplane mode, not really sure what else to do.

Does it happen anywhere you use WiFi? If so maybe try fully wiping and flashing the firmware, or just bust out the ruu to make it easier, can't hurt to try it should help tho
Did you even try to wipe cache, as has been suggested twice previously?
Otherwise, if no major system changes, and the phone has just been running worse and worse, a factory reset may help; as I would have to think it may be 3rd party apps that are to blame. Backup your personal data, factory reset, and just start to install a minimum of apps, and see how it runs.
If still no improvement, the above comment to try to RUU is not a bad idea, either. RUU provides a fully "blank slate" and may solve your issue.
My Nexus 9 is running slow most of the times and it takes while to I switch between apps or open an app most of the times...what is the fix for that? I have been trying clearing the dalvick cache several times but no help...and I really don't have lots of apps. Thanks for your help in advance.

Firstly, you need to face the fact that 2GB was a bad decision by Google for this tablet. There is nothing that we can ever do about that. :crying:
If you want to stay on stock, Chrome is the main culprit in consuming Ram. Switching to Habit Browser makes things better as well as changing your DPI to 288. Do a search on XDA regarding this. Whilst it improved things, it was still not enough for me.
I snapped a week ago and have now rooted and flashed CM13 and stuck with Habit. I've been using a few days now, and for the first time, I can keep my 3 Fantasy Premier League Tabs open, (they are huge,) without constant refreshes, redraws and lag. :victory: Right now, I feel for the first time, I'm getting what I paid for and the Nexus Experience. The only bug so far, is that always listening doesn't work.
If you've just bought this tablet, I'd consider returning it if you are not prepared to root. The performance will never be acceptable on stock.

Clearing dalvik cache will do precisely ONE thing and ONLY one thing; make it take a long time to boot next time as it regenerates it.
Ignore the amount of available memory. People who are concerned about the amount of free memory are trying to apply bad mswindows knowledge to Android. Totally different and no comparison. UNUSED MEMORY IS WASTED MEMORY!!!
So here is how memory management works in Android; it *preloads* everything that it thinks you are most likely to actually use, so that when you DO use it, it is more likely already loaded and starts up very quickly. If you are switching to something that is NOT already loaded, then it just needs to dump lower priority programs out of memory, which basically only takes a few nanoseconds (billionths of a second). So that is NOT it.
If your device is acting slowly, then you need to figure out what the actual cause is. Trace the CPU utilization with something like the "top" command (the one with busybox is a lot nicer than the one that comes with Android) while you are experiencing slowdown. You can also look to see if there is excessive I/O happening (i.e. read/write to the internal storage), and of course, some software will require a network exchange before it will start up -- nothing you can do about network lags.

You can do some investigation by watching the processes and seeing which are taking the CPU and memory on stock. The problem is, when you find out, there isn't much you can do about it.

Its quicker and easier to just install a custom rom where this type of work has already been done for you. :victory:
Lately, I've discovered that loading Chrome immediately raises my CPU temp by 30+ degrees. Sometimes that's enough to make things run really slow
Yeah, I agree...I will try to fimd sometime amd go over flashing a custom rom. ??
Yes! I habe noticed that these slow downs mostly happen when I am browsing in Chrome...
Web browsers are DEFINITELY a source of slowdowns.
The problem, more often than not, is actually *javascript* that is written by MORONS. Even on a desktop machine, you can watch the web browser for CPU and RAM utilization, and it just grows and grows and grows until you finally kill the process and start a new one.
What this may come down to is actually quite simple; the CPU in the Nexus 9 is actually more suitable for use as a stovetop than an actual CPU. These things get way too hot way too fast. If you beat on them with a web browser, they'll get hot and throttle down to low/verylow frequency, which will make them generally unresponsive. So if that is what is happening to you, there really end up being a few options to deal with it;
1) disable javascript in the browser,
2) don't use the browser,
3) improve the ability to disperse heat from the CPU.
For #3, you may note that when it gets hot, it is pretty localized to the corner of the device up near the power button. An easy solution to distribute heat better might be something simple, like adding a layer of copper foil to the inside of the back cover. The thicker the copper foil the better. Copper is very good at conducting heat, so this would spread the heat around over the entire area covered by that foil. http://www.ebay.com/itm/Copper-Foil...nductive-Adhesive-Ship-from-USA-/162018486132
I also found chrome was slow starting up, switching tabs etc. Found that logging out of my Google account in chrome improved this. Seems that synching tabs etc triggers the pause. This might be an acceptable workaround for some but I appreciate it isn't a great fix if you want to use that feature. Actually I'm not bothered as I think Google know too much anyway. �� But the underlying problem is this tablet... I don't have this problem on my phone.

I don't agree with that.
We use our N9's *all of the time*, and there is never any perceptible slowdown. Possibly with the exception of straining them with web browsers, but web browsers are... poopy... on EVERY platform and device, so that doesn't really stand out. Typically just minimize the use of web browsers and all is well.
Web browsers were good in 1996 when they were simple things to display an html website. Since then, they've added all kinds of useless crap to them that bloat them out, hog up tons of memory, and just generally make them into a useless waste of space.

I also uninstalled some other apps alogaide that which I was never using them,so I am not sure if the weather app was exactly the reason of the slow downs...but the other apps where just some games or some simple apps....well, I hope this information helps!
