Hello everyone,
Has anybody else who updated to 4.1.57 find that their Atrix is now kinda sluggish? I don't mean all the time, but every now and then I get random stutters or sluggishness when switching between programs. A couple of times, it even screen locks for a few seconds when waking up. This has never happened to me before with the 4.1.26, where programs just run without hesitation. They either run smoothly, or FC in the process. But now, some of them just becomes jittery.
I wonder if it has something to do with Motorola's battery improvement in the update. When it got sluggish on me, I decided to go to into setcpu to see at wat speed the phone was running. I noticed that the phone was throttling severely all the way down to 216 mhz the second the phone is not being used. it fluctuates up and down but it seems to always drop down there once i dont touch the phone. I think this is causing an issue cuz there's a lot of background apps and widgets running and once you try running an active program, it takes a split second to start, and that split second causes it to stutter.
I haven't had the screen lock in a while, so that's a good thing. But it seems setcpu can't seem to force the cpu to constantly stay high, even if i put the minimum to 1000mhz, so I get those stutters every now and then.
Anybody has any suggestions on this matter? Im thinking if this persists, I might just go back to 5.1.26 until they come up with a major update. Really the only reason I updated was cuz the prompt was driving me mad.
p.s. another way I know how the cpu isnt running a constant 1ghz --- my phone isnt as hot as it used to be. it used to be so warm in my hand, my hand would turn red from holding it.
It takes very, very little time for a modern CPU to change its clock speed. Monitor your computer's CPU clock closely sometime, it almost certainly does throttling to a similar degree. I also observed similar levels of throttling via tegrastats on my Atrix prior to the update.
Personally 1.5.7 has been good for me, at least in the sense that nothing appears to be worse after.

Only heard good reviews on 4.1.57. Can't wait for Bell to issue it too
lol, i dont like throttling. All my PCs n laptops run on full speed (throttling disabled) whenever they're on. I expect the same with my phone x) I just don't like any lag but I understand wat you mean. I still wanna hear what other's feel about the update.
note: I'm about to deodex the phone in a bit. Let's see how it ends
Moving stuff around in device memory is an order of magnitude slower than your CPU changing clock speed, and moving stuff between flash and device member is an order of magnitude or two slower than that. CPU throttling isn't the right place to look for this sort of issue.
As for your computers and not allowing them to throttle...enjoy the power bill I suppose. Even in overclocked scenarios modern processors work just fine with throttling enabled.

Atrix 4.1.57 issues
I have had my Atrix for over a month with no issues. After the 4.1.57 update I have the following 3 issues:
1. The phone randomely reboots (never did this before the update)
2. The cell signal is much weaker; no signal in areas where it had signal before
3. Apps seems to start slower.
I called motorola technical support and asked if there is a way to un-install this update; the answer is NO, all they can come up with is a factory RESET which will not remove the update but will remove all my data and Apps.
I finally sent the phone to AT&T and got a replacement with 4.1.26 and it works fine, especially the battery life and the cell signal and no reboots so far.
I'm getting rather fed up with my Rezound. My battery life has been poor, and I am constantly dealing with all sorts of crashes and glitches. I've gone from Sense to AOSP and back again, and since JB came out with working Bluetooth have stuck with JB. I've wiped and started from fresh so many times, and though everything works fine at first, it seems to just be a matter of time. I don't want to nuke all my Titanium Backup backups but I'm getting to the point where I don't know what else to do.
To the point: Is there a way to test and confirm the integrity of the phone's hardware? I know that some PCs can test hardware via BIOS, so I imagine something similar might be possible with mobile devices. This is most likely something that could not be done while running Android, due to the compartmentalization and sandboxing implemented in the OS. I want to test the RAM, NVRAM, and the CPU (possibly with a stress test though this can be done through Android via apps) and find out if there are any hardware issues.
On the other hand, if I'm going in the wrong direction, please let me know. As aforementioned, I'm running JB AOSP, been going back and forth between Wildstang83's CM10 build and Neo's RAGE (currently Infection). I've stopped trying different kernels as my battery life sucks either way. Recovery is AmonRa 3.15, HBOOT is 2.27.xxx, baseband is 2.22.10.0801r/2.22.10.0803r.
Problems include screen freezing on wake (soft keys light up, screen stays dark and doesn't respond); System UI crashing, generally followed by whatever app I'm trying to use such as Messaging, and often results in wallpaper resetting to default; ANRs in Maps and other apps; Phone crashing when trying to make an outbound call; poor battery life (I've killed all startups and stripped down idle run apps to bare minimum, it doesn't help, I replaced the battery about 6 months ago) and various other issues.
Phone has never been wet and has no significant damage; it has worn rather well for being over a year old.
Kernel tuner for "bios" type stuff and stability test for stress testing. Undervolting helps save battery for me. I also use dancedance/badass governor. Idk about your bug problems though, I have had issues with restoring data from old ROMs that completely made a new ROM unusable

You got a good point. I've just tried a fresh setup, restoring only data for user apps. We'll see how things go.
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

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*)

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

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.

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.

try flash custom kernel..the memory management is very good with custom kernel

Thanks. I am still on the official rom, I probably should switch.

Try tapping on 'Memory used by apps' on that memory settings screen, should let you know what the culprit is

I have done it several times. As I said, I really have not so many apps and just the very common google apps are installed.

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.

Thanks for your reply. Yeah, most of the times, the slow down happens while I am in chrome and browsing..it actually is not snappy at all in internet browsing...however, I remember it was back in the days that I had bought it.
No, I have this Nexus 9 since last May I think, but have not yet found the time to root it and flash a custom kernel and rom . Anywyas, I have done it previously for my other devices, so not that much rookie in it. Probably will give it a try,

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.

Thanks for your kind reply and explanation.
I think that is exactly the problem as even sometimes switching between the apps that I have just opened is also so slow and the nexus lags badly....Yes, I am aware of the network lags, but the problem I was talking about does not have anything to do with it...I will try the command you said, but can I run it on stock rom? I have not yet rooted my nexus nor flashed a custom rom.
Thanks

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.

Yeah, they do get hot...and the browser is the problem, I agree...however, I think they are not the main reason...there is something wrong with low memory or maybe some apps...

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 know..but everyone knows that N9 should be faster!...

Update:
I think I have kind of find the problem of low speed of my Nexus 9...I uninstalled an app that was for weather prediction and from that time on my Nexus 9 is very fast and responsive...No problem so far. 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! Let me know your idea. Thanks everyone
