[Q] cm6 slows down then crashes

i was doing my 5k run with my recently updated hero and about a mile into the run pandora radio started skipping and then stopped. when i looked at my phone it was rebooting. i have task manager and killed all the apps before i started and unchecked jogtracker and pandora so i could use them. it didnt last long. the phones screen froze and dimmed then crashed until it finally restarted. is there a reason for the crash. seems to me like a memory problem. i have a two gig card with one pt. five left on it. and the internal memory is at 91mb. it always worked before i rooted and installed cm6. the phone in general is way faster and more responsive since i put cm6 on it but for some reason the two apps running together arent working. thanks for any help

Try removing the task manger reboot into recovery and wipe Dev/ cache and try it then might work good luck

I've tried running with and without various task managers and always wind up uninstalling and reminding myself that I should know better.
I seriously don't think Froyo and these mods need a task killer. If anything, they seem to cludge things up. My phone was running beautifully for two weeks and earlier today I thought I'd try out a different task killer. Mistake. I uninstalled it after 1/2 hour because it just made the phone feel funky.
Try running without for a couple weeks....

+1, CM6 does not need a task killer/manager. The best method is to download AutoKiller (which lets you alter Android's internal memory manager, much more effective than task killers) and change the settings to Strict or Aggressive. Also, two of the biggest problems that create soft reboots that you describe is (a) the VM heap size being too small and (b) CPU speeds being too high. So, steps to take:
1) Uninstall task killer
2) Install AutoKiller and change settings to Aggressive
3) Change SetCPU/Overclock Widget settings to 691 max/595 min with screen on, 480 max/245 min screen off
4) Change VM Heap size (in Cyanogenmod Settings) to 24 MB and reboot
The only other possibility I can think of would be kernel instability. If you flash Decand3nce's #14 Stable kernel found here it is far more stable than the stock kernel and (IMHO) has much better performance than the stock kernel.
These steps should rectify any memory and/or CPU overconsumption problems you are having that could cause the reboots (as well as make your phone much faster, smoother, and more stable). If these steps don't fix it, it most likely is a problem with one of the apps themselves.
Good luck!

thanks for the help.
also on the restart i got this message Sorry the applicating spring updater (process com.sprint.ce.updater) has stopped unexpectedly. please try again. force close. this is probably the cause of all the problems thanks
the changes u pointed out seemed to have fixed the phone so far. thanks so much for the great instructions. u da man.

i noticed a couple times a day the phone reboots. should i back off of some of the settings.

Yup, lower the max cpu.

what is the VM Heap size for what does it change. mine is at 16 right now.

Its the amount of memory each application can take up maximum. You tend to get smoother running stops with higher vms; I set mine to 24.

To many freezes

Guys my Nook is freezing sometimes.
I have to shut down manually with the power button .
I am running right now nightlies 102 with OC 18/06.
But I had this problem and with Phiremod test Rom.
I have install the rom to my internal emmc.
any suggestion?

Isolate the machine..by this run without the OC kernel..or try running a different version of cm..many time on my machine with the nightly updates it does also freeze..I always to back to one that does not freeze..remember you are flashing test builds and they must be treated as such. Also..what speeds are you using...are you running setcpu with at boot option on..which you should not do. It WILL lock up..have you deleted any of the .apk files? Did you clear the cache and dalvic?

I will try to clear the cashe adn dalvin. No I dont use setcpu I know that it will crach with the preinstalled performance settings.

Try a complete flash with a differently nightly..what I mean is wipe all 3 (dalvic, data and cache and try just to boot) some times the nightlife are not very friendly... Build 110 comes to mind...it froze up..had to do a complete restore..frankly...I am getting tired of always flashing theses...my favorite is build 64 with the 1.3 sped kernel. For me this was running just right. I am going to flash 112 later tonight and I want to write a guide to which apks to remove safely for new flashers..I been meaning to write one for awhile..

Try the new CM7.1 RC release. I always do a clean install whenever i have freezing issues or i feel that nook is running slow.

To many freezes,
Oh how dare you mock me so.
Power off again.

sounds like SOD...
SOD: http://forum.xda-developers.com/show....php?t=1108964

I have put nightlies 112 now.
For the moment I had not any freeze only one time SOD.
But I have not use too much the Nook those days. I have exams

It doesn't look like Sleep of Death. My NC is not sleeping. Just when I'm in some application (for example, Angry Birds) it becomes extraordinary slow.
I exit the application and it is slow in launcher screen. Looks like frozen, then after several seconds it starts reacting on previous gestures. Then long delay again. Have to power off or reboot Nook.
I saw it yesterday for first time. My Nook was turned off for ~2 weeks. Then I turned it on and updated some apps in market. I noticed Netflix app was in memory. I don't think it loaded automatically at start up before.
I have CM7.0.2 stable, with normal kernel at 925MHz. I installed more than 100 apps, maybe one of them is the reason. It happens quite often, maybe once in half an hour. It can also happen in market during update. Nook is unusable right now.
But my friend has CM7.0.3 and he didn't install that many, I believe he has the same problem.
Will try to wipe stuff and to prevent unnecessary apps from starting with autostarts. Will see how it goes.

With that many apps...make sure you clean out the cache frequently...there are a few apps that do that free on the market....when got got my first android device...a evo I would load everything I could under the sun and delete and installed like crazy....now I have a few trusty apps and I clean out my cache everyday....browsing along will fill up the cache like crazy...

The only reason to do this kind of nonsense is if you need more space in /data, which is unlikely a problem on the Nook Color.

I have to disagree...I use firefox on the nook and after a few hours of surfing..it will slow down dramatically...clear my data cache and speed goes up...Also...the more apps loaded the more processess and services runningcin the background which results in overall slowdown...I really don't know why you call it nonesense when it is simple math..the more you have and use the more it is caches and or memory is gutted down with more crap running on it in the background and or swapping in and from cache.

I wiped cache partition and Dalvik cache using CWM recovery. NC looks better now. Didn't freeze so far, but I need to test more.
Thanks
PS. I rarely use browser. It froze while playing some game, or immediately after exiting game, in Zeam launcher.

I don't do the dalvic cache...I am talking about the general cache...currently using 'cache cleaner' from marketplace and works like a charm.

my nook has been freezing a lot lately too. randomly. it doesn't slow down or anything, it just freezes and I have to hard reboot. at least 3 times a day. I am on nightly 116, this has been happening since beta 3.1. using 6/18 kernel. overclocked to 1175.
sometimes it will even freeze right after the bootanimation as soon as it gets to the main screen. Any ideas on what I can do? I have changed the kernel from conservative to ondemand and that didn't help. I lowered the overclock from 1200 to 1175 and that didn't help.
edit: as I was typing this it froze while clicking on the dropbox app. I restarted and it froze as soon as it got to the homescreen. also just cleaned the cache. freed up a lot of memory but it didn't help.

Slow clock down to stock..or flash another build...also just use cm for over clocking if you are using setcpu..uninstall it..I don't know if you are. Try interactive...if still freezing..with setcpu..yes..reinstall..basically try different combos...when you find one that is stable...backup and use that as your daily driver and then experiment with different build.

I cleaned program cache too, with Android Assistant. I guess it's the same. Nook froze badly today. Played Angry Birds, froze completely. Pressed "n" button, exited to launcher, but could not do much in it. Only long-press power button helped.
The thing is it worked well two weeks ago. Then I didn't use it, then I downloaded few free apps from Amazon and ran out of space on eMMC. Then I moved some apps to microSD (I don't think I moved Angry Birds but it looks like it is on SD for some reasons). And my microSD has bad random access times. Can this be the reason?
People in this thread http://forum.xda-developers.com/showthread.php?t=1005633 reported problems when booting OS from slow cards. It probably applies to apps on SD too. I bought Sandisk card now, but it will take time to deliver.

Captivate seems slow no matter what ROM

I don;t know what is wrong with my captivate.
I have flashed a lot of roms and no matter what I am having this issue.. I install a ROM, set up only my email, and only 1 or two apps.. nothing special
and everything seems to be slow and laggy and just not very usable.
any ideas on what I can do , my last resort is to try to install just a stock rom and see what happens.
its getting me pretty mad really.
ideas, help, i have searched and found this issue with other phones, but not with the captivate.

Hmm weird,probably try getting back to stock and then master clear and then again flash back to the rom of your choice.....!
note:master clear will delete everything on your internal memory card make a backup of imp data before clearing.

Try installing a cutting edge rom with voodoo lagfix. If this doesn't work, you can always just send it back to At&t for a new one if your warranty is still valid.

Its always a good idea to ODIN back to stock and/or Wiping data, cahce and Dalvid cache a few times.

How slow is slow? Quadrant is not always the most useful, but it might be nice to know what your score is for the sake of a baseline.
Just fyi, my current setup gets me around 1700, but stock was pretty solid at 975. If you are getting decent scores, then try using a system monitor to see if a service or app is chewing up your CPU cycles. If your scores are very low, then you may have a lemon.

it just seems laggy and almost unusable. example: a compleatly clean phone with no data but Gmail set up, when i go into the market it seems really slow to load the market, then i insall Facebook, its slow as hell, laggy no matter what i do.
there is nothing installed on the phone
i will try odin back to 2.2 stock and see what happens.

SuperCharger made a huge speed difference for me. Unfortunately I still have occasional stability issues, so I'm considering installing ThunderBolt!, which uses Supercharger's script but with their own LMK/ADJ/OOM.

My Experience with Lollipop on Nexus 7 (2012)

Hello,
I've updated my Nexus 7 first-gen recently to Android 5.0 and since than have spent a good amount of time using it. I use the tablet for work and fun through out my whole day, so snappiness is a big factor for me. With the 4.4 update, the tablet just got a lot slower, sometimes I needed to wait for a few seconds before I am able to kill a task. Clearing cache didn't fix the issue.
Made me think about that 5.0 update a lot. (Note that I actively started using the tablet only a few months ago. I had it for 2 years but broke the screen 3 weeks after buying it and only now I decided to repair it.)
The 5.0 update it self took a good 45 minutes. When I loaded it up for the first time, man it was buggy, I couldn't complete a single task without it bugging out. All of the Apps and settings were there untouched. The first thing I did, was go into recovery mode and cleared the cache. Then I cleared the cache for every individual app. And that boosted the performance by 100%. Next, the animations, I cut them down to 0.5x and turned on GPU rendering (just for testing) turns out that helped out a lot. I didn't notice a difference in load times, like some articles suggested.
However there are a few quirks, the sound lags behind the slider, so if I crank up the volume to MAX it will take a moment to do so. I often found my self having to tap the apps drawer button more than once to open it. And the killing of tasks is not as easy as before, now you have to slide from one side to the other in order to kill a task you can't just kick it to the side. Also, the auto-brightness is really aggressive so I disabled that. The WiFi status, when you click on a WiFi connection seems to be broken since in portrait mode all the letters are separated, and at first I couldn't make out any of it. And the biggest downer for me is the keyboard, I think they didn't do any favors with it. I have larger thumbs and it will take some time getting used to the keyboard. These are all small things, but they affect my experience.
Now the good stuff, where do I begin? The interface, it's great I like the design and the contrasts. Performance, I guess that's the biggest question since this is not exactly cutting edge hardware. To summarize it, it's good. I haven't had any issues since I cleared the cache, apps are running as they should, games as well, multitasking is as expected, fluid. Later on I switched the animations to 1.5x and 2.5x. no issues there. Boot up times, something completely irrelevant to me, but since there are people that would like to know, it takes around 30-40 seconds to boot up. However, Chrome is still the biggest enemy. If you want something to make your tablet miserable and make you wait and get frustrated because of it's unresponsiveness, you won't need to search far, just get Chrome.
All in all, the update was a step up, and an improvement.
These were my 2 cents on the subject. Hope it was of use to someone.

thanks for the review. I also updated a few days ago when the ota came through. So far, I'm experiencing terrible lag. I don't have anything stored on the N7 and don't have many apps. There is a ton of available storage on my 32gb. I did a factory rest about 3 months ago, as I like to every now and then to give the N7 a fresh start. I think I may have to yet again and keep my fingers crossed. Unfortunately, it's unusable at this point.

My experience has been variable, but not unexpected. In the past I have had issues with installing OTAs resulting in poor performance -- sluggish response to touch, certain apps immediately displayed odd lag, etc. Going from 4.4.4 to 5.0 was no different. So, I performed a factory reset and the effects were stark. The performance is exactly where you would expect it to be for Lollipop i.e. it is smooth.
HOWEVER, all is not well. There seems to be a set of problems that I suspect is related to Lollipop utilizing the ART runtime. Certain apps, even before performing a factory reset, were really really slow when running the first time. I have experienced this before: when I tried out ART when it became available on the Galaxy Nexus. Two common apps this occurs with are Facebook and Mint. Who's to blame? The app developers? Google? Don't know but hopefully these issues get resolved soon.

Ugh, that is quite an issue. Have you tried wiping the cache? You should check your usage, you might be able to find out what's hogging your system, unless it's the OS it self.

I also tried out the ART on some devices, mine were not even supported. There were a lot crashes but I also noticed some performance improvements.

Does factory reset also wipe the cache?

My Lollipop experience with my 16 GB WiFi-only Grouper isn't as good as yours. First, I thought I messed something up by rooting it with NRT, but after a manual factory image (flash-all.bat failed out of the box) without root it didn't get any better.
Most time its not as responsive as my N5, I've already had 1-2 minute hangs followed by hung apps (Google Search/GNL, system in most cases) and heavy lagging under most conditions. From time to time its getting close to 75-80% of the smoothness experienced on the N5 (which has better hardware, of course).
I have no idea what went wrong, I've already enabled 2D GPU hardware acceleration, but I'll definitely wipe the cache in recovery once more - you never know...
Thanks for the extensive review - Chrome is just a pain in the a** if you don't have at least 2 GB memory available.

One thing I forgot to mention is that after the cache wipe the tablet was fairly fast but I also went into Settings > Storage, and noticed I have a lot of app data which frankly shouldn't be that much. I then went and cleared cache manually on every app and as it turns out, I managed to scrape off another 1GB there. So, I'm not sure how that would affect the overhaul system performance but it sure helped me get the snappiness I have right now.

Looks like wiping the cache had an impact on performance. I wasn't able to play around much, but it definitely felt faster after first reboot.
Too bad I just noticed my user partion only had 6,x GB (8 GB image obviously) - there are so many ways you could f**k up an Android system - so I'll have to format user data once more, approximately the third or fourth time in the last week.
Sometimes I understand why people fancy those awful Apple devices, but let's hope the speed boost persists.

Go in and delete all the apps in system folder that can be installed from play store and are not needed. After installing the lollipop images you have 11mb in system which seems to be main cause of lag. I freed up like 160 mb and no lag or stuttering. Not sure why google kept things like dialer and other things unusable on the tablet in there.
Also get now launcher and delete launcher.
For even better performance get faux kernel (Set kernel up to his recommendations) and/or install aosp 5.0 F2FS with minimal 5.0 gapps.
Oh I do have a problem with WiFi being weaker on 5.0 though.

i am getting terrible lag too. last week i updated with the OTA file. wiping the cache improved performance but only for a short time. i guess eventually if ii want the speed back on my 2012 nexus 7 i am going to have to root and go back to jellybean

Thanks, that sped up things significantly. It's definitely a memory problem, because event on full stock setup you're getting glances of Lollipop smoothness.
But WTH is Google delivering a potentially lagging factory image? Couldn't they just resize /system by default in order to fit in all apps nicely? Well, that's Android - if it doesn't work, you have tons of options to fix it.

After my old N7 screen broke, I got a new refurbished 16GB unit for about US$100.
Had some bootloader issue earlier while trying to flash lollipop, and had to revert back to 4.2.2. Then it got all the OTA up to lollipop, and is running really well since.
Loving it now, better than most non-lollipop newer tablets around...

Lollipop is big disappointment. I hate new notification (double swipe down to access settings)
I am back on 4.4.4 Slimkat rom with Legokernel and f2fs
now is system smooth without lags

Listening to some of the advice in this thread, I rebooted into Recovery and wiped cache (I did it 3 times, because why not, right?)
In addition, I went into the developer settings and turned OFF "Force GPU".
After doing both of those, my performance seems to have greatly improved (specifically Chrome, which was borderline unusable).
For reference, I flashed the factory image from 4.4.4, and didn't get it OTA.

Not any more! I have three new iOS devices and things are far, far worse since iOS 8 dropped. Apple now holds the lag crown. At least with Android you can revert back to earlier versions that worked. With Apple all you can do is whimper at the master's feet.

UTTER nonsense. Stop it. System being full affects nothing; it's read-only.

Is there a way to disable the storage encryption that is enabled by default? Disabling this apparently had huge performance upgrade for the nexus 6

understand what you are saying but after doing so i have no lag.
Have 2 x 2012 and both were lagging. After trying other things i deleted stuff in system and both are very smooth now. Very happy with them.
Even wiped and re installed one and just deleted stuff in system, to make sure it wasn't something else or a combo of things i did prior.

Laggggg on Marshmallow or is it just me?

My UI freezes for 5 - 15 seconds, particularly when the phone regains network connectivity (reconnecting wifi or mobile network going from 0 to 1 bars). It's much improved after removing FB and Insta but. My launcher is even getting closed when the phone frequently, although the phone has ~500MB free RAM.
I dropped this poor phone one too many times, so before I replace it with another z3 compact, I'm wondering if everyone else on Marshmallow is seeing poor responsiveness as well.

I did have slow downs before but not like that,I have switched to Lineage and it works very well so I don't have any plans going back to stock Marshmallow.

yeah same here, i advice you to switch to lineage, you will feel like butter on the screen.

I don't have any lags at all, no launcher refreshes or whatever on stock MM. ( I don't use the horrible Facebook application)

Until 3 weeks ago, I used to have no lags at all on my stock Marshmallow 6.0.1 Z3C. I had uptime of 50 days and more and it didn't lag. Now, it happened twice in a row that my System RAM usage grew in last 5 days to 1,3 GB! It seems like a memory leak in kernel space. It's hard to pinpoint particular process. The phone is slow, multitasking doesn't work (reloads every app), my stock launcher redraws and the phone is unable to make/receive GSM calls - probably a symptom of low on memory state. I wonder, if it's caused by bluetooth driver, because I've transfered 100MB file on both occasions. I need more time to analyze this, this time I won't turn bluetooth on, so I can see if it is the cause.
Edit: I'm confident the cause is not bluetooth. Symptoms now appear after just 65 hours of uptime - . Now I tried to get rid of ES File Explorer, let's see what this bloatware did to system performace.
Edit 2: It seems the problem is gone after uninstalling ES File Explorer. Before uninstalling it had data storage set to external SD card. I replaced this piece of bloatware by open-source explorer called Amaze.

Thanks all. I was avoiding Lineage because I wanted the stock camera / DRM and their description makes it sound very unstable... "random reboots while charging", etc. I'll try it out anyway and add the stock camera back in if it runs well.

Do share the source of the issue if you find it. I'm still seeing UI lockups when the phone loses internet connectivity.

camera works like stock in lineage, don't worry about that. you can face with other small bugs but still worth to use, it is better than stock in most cases.

device gets VERY slow (i mean like 10 seconds to open the phone dialer or whats app)
Even did a factory reset, which only helped for ~2 days ...
same problem with my girlfriends Z3C.
Something is very wrong here ...

Until 3 weeks ago, I used to have no lags at all on my stock Marshmallow 6.0.1 Z3C. I had uptime of 50 days and more and it didn't lag. Now, it happened twice in a row that my System RAM usage grew in last 5 days to 1,3 GB! It seems like a memory leak in kernel space. It's hard to pinpoint particular process. The phone is slow, multitasking doesn't work (reloads every app), my stock launcher redraws and the phone is unable to make/receive GSM calls - probably a symptom of low on memory state. I wonder, if it's caused by bluetooth driver, because I've transfered 100MB file on both occasions. I need more time to analyze this, this time I won't turn bluetooth on, so I can see if it is the cause.

there must be a reason that it is slow as hell in stock while it works with jet speed in lineage. something related to sony software, hardware is okay.

Wipe cache (Power and vol+ until 3 Vibrations) helped a little, but i don't put too much hope in it.
It's my gf's Phone so i kind of hesitate to install some unstable beta on it. Or is there any real stable release out there?

Sony haven't pushed out any updates for over a year, so not sure how you can blame it on MM build.
It'll be an app.
My money's on Facebook or Messanger.
No lags or slowdowns on my phone, had the same build on it for a year now.
Autoupdates turned OFF.
No Facebook/Messanger.

Guess you're right, but i can't really accept a SD801 Phone being unable to run basic apps like FB

Last year Facbook deliberatly broke their app, made it run slow and heat your phone up, as an experiment, to see what people would do. They honestly don't give a sh*t about what you think of thier app.
Uninstall it and use your browser, see if it makes a difference.
Try SD Maid from the playstore, that does some good basic houskeeping

Nope.
I do not have a Facebook account.
Therefore I do not have facebook or messenger installed.
But I do have these slowdowns :-/

I read in an italian forum that it's the Google app fault, you should unistall updates and disable automatic updates until it's fixed.

It seems the problem is gone after uninstalling ES File Explorer. Before uninstalling it had data storage set to external SD card. I replaced this piece of bloatware by open-source explorer called Amaze.
Now I have an uptime of 125 hours and counting, my System RAM usage is 0.90 GB and it isn't rising to 1.3 GB as it did before. So the phone is really smooth again. When I was checking my LogCat using DDMS, there seemed to be recurring message of ES File Explorer (estrong) leaking something, I don't remember if it was a window or an activity. What a piece of chinese malware it became. Interestingly, ES File Explorer's memory footprint was low (3 processes, 10MB total user space memory), even when leaking memory and this made debugging harder. Although I killed it, when the phone had problem (1.3 GB system memory), only a reboot worked. It totally seems like a memory leak to me.
GL debugging yours.

it works good with me ..
try to make clean install

I'm not going back to this crappy app. Once, it used to be outstanding, but they probably sold the app to another company in China and from there it went downhill. A lot of popups and ads for things I don't need. Their only purpose is to make your phone slower (bloatware) and optionally, to get money from you. I like simple, minimalistic apps, which do things they are designed for and do it right. Just this Linux approach and also "less is sometimes more".
It's confirmed that ES File Explorer makes network connections to China in background, no thanks!
