[Q] lags, high cpu and assorted sluggishness

I am using CMYLXGO's NAND stock Desire HD build. Its great. However, I am having so many lag issues. I seem to be one of the few that is experiencing this with the build so i turn to some of you to see if you have had similar issues with your phones.
Problems:
1. when auto populating apps (like using installer, uninstaller, managing applications in the system tab) the phone will take forever to pull up all the apps , the screen will cut off (because the screen times out) and when I hit the home button or any button to cut the phone back on it stays black.
2. every action makes the cpu run high. adding a widget to the home screen (apps populating issue again), changing screens really fast and other assorted minor processed.
I have stopped auto sync
I do not use auto rotate any more
I do not have any rogue processes for the most part
I don't understand why I seem to have these lag issues. Everyone else talks about how fast and fluid the build is. I am under the impression that with the build NOT being run from the memory card NAND would add to speed. This is not happening for me. If anyone has any idea why this is happening. I am convinced it is something on my end but I don't know where to start. I am open to suggestions.
I have 2.15 radio, 16 gig class 2 memory card.

Hmmm, not sure but have you tried another ROM similar to see if it does the same? You can also go into MAGLDR and wipe dalvik cache. I used this ROM and all was good for me. I have sense been using this one which is also working very well.
http://forum.xda-developers.com/showthread.php?t=976384&page=1

every version of this build has been tried. That is the part that gets me. differnt kernels don't help either. i have even used SetCPU and overcloced to try and get through some of the lag. it works, but it is only when I play games not when I need to perform uninstall or widget selection for the home pages. I use SeePU which is ususally shows my cpu strain in the bright orange (for high use). most of my processes/actions raise the cpu use to high levels. I never really operate in a green (or low) usage level no matter what the action is. I would really like to capitalize on the speed NAND is supposed to offer.

Personally I would try something else (a totally different ROM) and see if you are still getting the same results, maybe even revert back to a windows mobile rom just to see if you are still getting the hang up. Last option would be to restore your phone to stock and start over, reinstall HSPL 2.08 new radio, etc...etc...

do you use an app killer?

yeah. but i did not at first. however, it is needed to stop some of the rogue processes. android.process.acore comes to mind.

I personally think this is one of the most stable builds around. I would rarely experience any lag, and if I did it would only last for seconds.

Believe me, I know. Everything is working in his build. GPS, MMS, easy to install - the works. This is why i really want this to work properly so I can use it, without the hiccups, as my daily build. It has to be something with my phone but I can't figure out what it is yet....

On Cmylxgo's build, the first time I loaded it, I had the laggy and unresponsiveness you described for the same reasons. What I found is that rebooting the system to off/on a couple of times when I first loaded the build, addressed the first initial lag and unresponsiveness. After doing a couple of reboots, I found the build as smooth as everyone says it is. I am now trying the GL Core v11 kernel and it gives an extra 300 pts to the Quadrant Score and seems to be a bit quicker than the Rafpigna 1.8 kernel that comes with the build. Also, standby battery drain seems to be a bit better with the hourly peaks at half what I see with Rafpigna. If rebooting a couple of times doesn't do it for you, I know trying another build which may not have all the bells and whistles as Cmylxgo, but it is worth a try to see if it makes a difference. For me at least Cmylxgo's stock Desire (HD)2 build is much faster and smoother than any of the MDJ SD builds I was using.

Help me to get rid of the lag

hello,
i'm getting crazy with this annoying micro stuttering and occasional lagging. it's happening everywhere - home screens, app drawer, settings, apps like xda and tapatalk. it's not major, but it's enough to be seen and to drive me nuts. i tried stock KK, Cloudy stock 2.5 and Cloudy G3. i also tried several kernels - stock, bruce Kernel and Dorimanx. i also tried tons of different settings for cpu governor and hotplugging; i tried the lag mod which have to remove the scrolling lag - it seams that nothing is helping. i tried with and without Greenify (to avoid a lot of resident apps), i also tried both Dalvik and Art - nothing. the slight lag is there - and it's just that - slight stutter, few frames dropped - enough to make you think that some setting will kill it finally. but no matter what i try, that slight lag and stutter is still there. can you give me some suggestions - i'm coming from Galaxy S3, which i used with Beanstalk rom - i experienced 0 lag and stutter and i cannot believe that i see that in a phone like the G2, given the powerful processor and the 2 gb of ram.
please help me not to get insane with that phone

I've only got 550mb of ram free and my phones flying. Not even a little bit of lag. But for the first week or so after re flashing the stock Rom I did get all that lag you were describing. Even after I debloated, flashed Bruce's and did every other mod you can think of. It ended up going away on it's own after a while. Maybe you just need to stick with one setup and let your phone settle.
You can use beanstalk on the g2 as well, if you were interested in going that route again.

I have the same issue. In games it lags and stutters just enough to put you off the game. I have noticed some videos do this as well like youtube. I am still testing this but I am reluctant to spend any time on it as it has a clear issue when other lower spec'd phones run the same games fine. Basic games as well. It is subtle, but the stutter is there. On some games it's can even be a full 1 or 2 second complete lag and game halt. I tried the CPU throttle option in hidden menus and this did nothing.
Can this be hardware problem? I phone LG and the support agent was extremely unhelpful. He said that it would be sent for repair and they will not play games, only flash it and run a test. I'm concerned this will be a classic case of "there was no fault found" and it will be a complete saga for ages. I already had this before with a different phone (different problem) and I'm fed up with phone problems.
Mine is from Vodafone UK store bought. I am tempted to try stock UK firmware to see if this fixes. Shouldn't have to though.... I also might end up trying a custom ROM to see if it goes away. I absolutely love the phone otherwise. I just want it to work.
PS: It runs benchmarks fine with high scores.

Any 5.1 ROM that isn't horribly slow?

I use CM12.1 on both my N7 2012 and N6 and it's incredibly slow on the N7. Clearing the cache does nothing, trim does nothing, F2FS /cache and /data does nothing and even the stock 5.1.1 image is slow.
I've read everything under the sun about poor NAND, not enough RAM, poor CPU, etc but none of them really make that much sense. I have hardly anything running EVER and I only have a few apps installed for opening documents an such. No Facebook or Email clients or anything that would be running in the background. The built in RAM manager tells me that I usually have over 50% of my RAM free and with such a small number of things running, my CPU usage is low, so I fail to see where the issue lies. I guess the NAND, but I also read articles about how that's kind of a load of bull as someone tested old 2012 N7s that had been heavily used and slow, as well as new ones and the R/W speeds were the same.
The main thing that bothers me about it is the fact that when I do a clean install of the 5.1.1 factory image or even CM12.1, it will be snappy for all of 10 minutes and then suddenly it becomes annoyingly slow. It's by no means unusable, but compared to my Nexus 6 every action feel like it takes 2-3 times a long. Even doing my pattern unlock feels sluggish.
I went back to KitKat tonight and it seems to run much better, but there are some things I've gotten so used to with Lollipop and Holo looks plain ugly now that I'd really rather not use KK. Does ANYBODY know of something I can do to speed it up even a little bit. This almost seems like a kernel related issue to me, seeing as how the N7 has been running off of an old kernel for most of it's life. It makes me wonder if there are some kernel-level things that might be done to help.

Turn off journaling, use trimmer and try Minimal OS

XenonHD and BSZAospLP run fairly well on my N7. I've got the 32GB model, which purportedly has less memory slowdown issues than the original 16GB model, fwiw.
If your flash memory has bad blocks in it, that will slow down your device whenever it tries to read/write data. A full format of the /system /data and /cache partitions may help. I can't remember if there is a way to mark off bad sectors from being used. You'll have to research that. You may have to do a special kind of format to remove bad blocks from use.

Well, disabling journaling did nothing and trimmer does nothing.

Dirty Unicorns with /data and /cache formatted to f2fs works perfectly with my n7 2012. I'd highly recommend it.

I assume you went from a full flash of the latest stock images, flashed latest twrp recovery, formatted f2fs for cache and data, flashed latest stable CM snapshot, and optionally installed the relevant open gapps as linked to on CM's wiki site?
Have you tried running this setup with no additional apps installed? Chrome isn't much better under this CM 12.1 installation than stock 5.1.1 for me, but everything else seems to run about as good as stock 4.4.4. One thing I do is reboot my 2012 N7 every time I put it on the charger

Chroma works fine on my N7.

Then you clearly did something wrong. Try with a custom rom like Minimal OS, Chroma or Ressurection. And with M kernel

What could I have done wrong? I flashed the file to disable journaling and I've always used trimmer... Disabling journaling literally did nothing.

im right there with you OP, my nexus 7 is ****. Doenst matter what rom, or what format (ext4 or f2fs). I slows to a crawl in a few mins of use, more often than not, takes forever to wake, and then will sometimes just go black before i can unlock, freezes constantly and requires reboots. I hate this piece of ****.

I've added
ro.config.low_ram=true
to the build.prop and I am running the Trimmer app once a day. There is still some lag from time to time, but at least it's useable.

G2 D800 Lagging, running absurdly slow?

Hi, so I've had my G2 D800 model for a while (about a year or two), and for the most part, it's been an excellent phone despite being 3 years old now. Never had any slowdown problems, and it's always performed well in games and in general.
But just recently, about a week ago, it just started lagging out and being very, very slow.
For example, if I'm watching a YT video through the app, if I rotate the screen, it takes maybe 5-8 seconds to actually rotate. Also, in a lot of circumstances where the keyboard has to pop up, it just freezes the app until the keyboard pops up maybe 10 seconds later.
It's also just laggier in general in most apps, scrolling through FB or Twitter freezes nearly every second when I'm scrolling. It's generally unresponsive and sometimes just freezes outright. It also acts this way on the homescreen, and in most everything else.
The most annoying part, however, is that sometimes the devices just doesn't turn on for sometimes up to 15 seconds after pushing the power button (and it usually just refuses to turn on when using my knock code).
The odd part, however, is that once it's actually in something like a game, it performs perfectly fine.
I've played a number of Cardboard games, as well as games like Nova 3, and it performs perfectly.
I've also ran multiple benchmarks (Geekbench, 3DMark, etc), and it scores around where it should.
Info about the device:
LG G2 D800
Stock Lollipop 5.0.2
Software Ver. D80030f
Kernel Ver. 3.4.0
Rooted
TWRP Recovery installed
XPosed Lollipop installed
G3 Tweaks installed, a number of tweaks applied
Everything else is stock (homescreen, etc)
What I've tried/checked:
Checked memory usage during "lag sessions", rarely dips below 300mb free
Changing minfree values through Rom Toolbox (tried every preset, as well as setting everything to the max to free as much as possible)
Rebooting (affects nothing)
Checked CPU speed with Rom Toolbox (is at max, and does achieve the max speed of 2265 MHz. Setting it to performance mode/setting the min speed to be 2265 MHz has no effect, but reduces battery time)
Changed default cache sizr (tried every preset from 128kb to 4096kb. With multiple benchmarks, the optimal value for r/w bounced between 512kb and 4096kb, currently on 4096)
Things I have not tried (that I am aware would possibly have an affect):
Changing anything in the kernel tweaks/build.prop
Completely wiping, reformatting, and reinstalling (I really would rather avoid this if possible, as it would take a while to get everything back to what it is now, and it was a pain to upgrade to Lollipop in the first place)
I am unaware of anything else I could try to fix it, which is why I'm here
So, does anyone know of any other solutions or things to try? This has made my phone very unreliable, even for phone calls and messages, which is a problem.
Thank you for your time and help!

Hi,
First thing i need you to try out is this custom kernel : http://forum.xda-developers.com/lg-g2/development/lp-5-0-2-kernel-3-4-107-dorimanx-1-0-lg-t3102512
Then install greenify, and hibernate all the unnecessary apps.
This should solve the issue.

Thanks for the quick reply!
I'll try out greenify, though there aren't many unnecessary apps running (i uninstalled all the bloatware first thing, when I rooted).
And about the custom kernel, it's something I've never tried, so I have a couple questions.
Will it wipe my device, or break TWRP, root, or Xposed? (Sorry, didn't see the answer on that forum)
Will a TWRP backup I make be able to fully restore my device to it's current condition?
Is everything that is supported on my device be supported with that kernel? (Apps, etc. Don't know a whole lot about how kernels work, so I don't know)
Thank you!

Hi,
Even you uninstalled bloatware, the apps you use daily could be running in background and taking all those rams. So whenever you play a game or dont use a certain app, just go to greenify and hibernate. Since you have xposed installed, you can do more than that such as u can stop sync , etc.
About the kernel, it has a ram management settings and cron task.
Ram management dont need to be altered. It has some preset profile so if you seek performance, just choose performance or if u need battery , select battery profile etc.
Cron task is useful because it will do alot of things automatically. For example, it will release ram at certain amount of time from the apps , it will restart google play service since that could be an issue , etc.
All you need to do is take a nandroid backup just to be safe. Then download Dorimanx Ota from playstore and it will detect ur device and show u which version of kernel is available. Then download that, go to recovery, flash it, and you will see three app installed : Synapse -- will give you all the details of ur setup including cpu speed, temp etc for monitoring purposes
Dorimanx settings - this is the main settings of the kernel. You will see a P icon on top, tap it and choose your desired profile.
Color management : It is as the title says, just leave it be.
Then use your device, check your ram and report back. Hopefully it will resolve your issue.

Wow. Dorimanx did a lot more than I was expecting.
Downloaded the app, downloaded the kernel, flashed it no problem, went through and checked out synapse.
Went into the Dorimanx settings, and set it to the "Performance" profile.
Immediate improvement.
The whole phone seems a lot more snappy, and I switched back and forth between a 1080p60 YT video, facebook, and twitter with absolutely no problem.
Free memory when idle (no apps open) stays around 1gb; it used to be about 500mb before.
Tested a few games for the heck of it, and it actually seems to have improved game performance somehow. (It seems to have overclocked my CPU to 2.5ghz, though, so that makes sense.)
Temps stayed at around 58-60c while running a few Cardboard apps, so it seems fine.
Thanks for the help iubjaved! This has fixed my issue and then some! Ah, the wonders of the Android dev community.

[Q] Massive, abnormal lag with any ROM

So I don't spend much time in the Nexus 7 forum since I rarely use this device. Thus, I apologize in advance if this is brought up a lot.
I'll admit I haven't done much searching on the issue because the hits I found never seemed to apply to my situation.
No matter what ROM I flash, I always end up with massive, massive lag.
Seriously horrible lag.
Like, it can take 30 seconds just to open an app.
CPU Spy indicates I'm hitting all core frequencies so I'm not sure there is a hardware problem, but I haven't ruled it out either.
My flash procedure with TWRP is to wipe EVERYTHING. Data, system, cache, dalvik, etc.
One time I even wiped internal and then transferred the ROM over using ADB.
Then I'll flash the ROM and set everything up.
Tried different ROM's, different versions of Android and different GAPPs.
Any suggestions from the collective?

Hi there. There is a thread for the Solution of this known problem
http://forum.xda-developers.com/nex...arrotmod-speed-2012-nexus-7-emmc-fix-t3300416

Thank you. I have actually tried that and while it helped a little, I still suffered from massive lag.

I just found that Android 7 is available from DU for this tablet.
Gonna give this a try later this afternoon.

I still have lag on DU 7.0

have you tried the carbon ROM? thats the most lag free N 7 ROM. But these are still in development initial ROM. There would be some problems here and there
