Phone has become laggy. Please help! - Samsung Galaxy Nexus

Hi guys, recently my gnex has become laggy. I don't know what the proper reason is. I have tried different roms and on all it's the same. After flashing a new rom once I use it for a few hours it becomes laggy. I have installed Facebook home (patched ). I have uninstalled it thinking it might be the reason and still the same. Any suggestion guys?
Thanks

Common issue on 4.2.2. There is a thread dedicated to this a few threads down.

Did u flash a 4.2.2 ROM ?
Sent from my Galaxy Nexus using xda premium

I have had this happen to my Galaxy Nexus couple of times, especially since the 4.2.2 update last December.
I know this might be a harsh solution and does take up a lot of time, especially if you have a relatively filled up sdcard (mine is usually around 6-8 gb), and requires using adb, but the best option/solution I found for this is to backup the entire contents of my SD Card to PC, wipe /sdcard, then restore all /sdcard contents.
Meanwhile, I also wipe /system and /data, transfer new ROM/Gapps/Kernel to phone and start with a clean set-up.
In terms of ROM, you can give ATOM a go (xda link in my signature). v12 for magure teamed with AK70 is blazing fast for me.
One thing I avoid doing is filling up my sdcard with music, as it seems as my sdcard gets filled it really slows down the phone.
Again, this is something that works for me, so it is worth a try if no better option is presented to you. As always, don't forget to back-up everything off-line before wiping anything. Best of luck!

Possible solution
Try using apps like Greenify which will makes some of the useless or unwanted apps hibernate for more free ram. Use sdmaid, it'll remove the junk and duplicate files from your phone.
You can also try scripts like v6 supercharger for better ram management and Crossbreeder mod for more entropy.
Try using xenonhd rom 8.0 with ak kernel.
My phone is buttery smooth, fast and stable.

here try this thread :good: !
that could be the reason..

Questions on best practice and most stable ROMS

So far I have always been running rooted stock ROMS. From what I read they tent to be very stable, the battery last longer, and do not lose some features (4G, HDMI) etc.
However lately, probably because of the apps I have installed, the phone is pretty slow, the memory on the phone is running out and does not work properly.
It is time for a complete wipe. However I am not the kind the person that change rom once a week. I would like something for the long term.
I have a few questions (feel free to answer to a subset of them):
1) I can I maximize the free space on the phone? On stock you can update a stock app (ex flash, acrobat reader, etc) but you cannot uninstalled. I was wondering if after the update, I have now the app taking twice as much space that is supposed to.
2) What is the best way to backup all the apps on the phone and restore them quickly, being able to chose what and what not? I am using Titanium Backup but it is not clear what is an installed app and what is system app. How do I guarantee that I do not lose the app data? I am trying to find a way that once I update the ROM I can configure/restore the apps that I want without having to spend hours on it. What I am afraid is to install/restore something that it is not going to work but it takes spaces on the phone. One of the thing I really want to keep is the email configuration (3 gmails account, 1 hotmail and the link with Facebook accounts).
3) I am using App 2 SD Free but there are some large apps that cannot be moved on the SD (gmail, facebook, qik, flash, maps, twitter, Google Music, G+, etc). Does any work around exist to save precious space on the phone?
4) Regarding stability, not bloated, and full features available on OTA (4G, Bluetooth, HDMI, etc) What is the best ROM? I was looking into Fresh Evo (http://forum.xda-developers.com/showthread.php?p=20101297), Swagged Out (http://forum.xda-developers.com/showthread.php?t=1258932), Sprint Updated 2.0 (http://forum.xda-developers.com/showthread.php?t=1321340), Clean Rom 1.0 (http://forum.xda-developers.com/showthread.php?t=1351890). I am leaning toward Fresh Evo because the author have been updating for a long time). Any suggestions?

Use A2SD, in terminal type:
SU
a2sd cachesd
Moves your Dalvik Cache to the SD Card. Free'd up about 200+MB on mine

It's actually very easy to tell which are user apps with TB. They're the ones in white text

MIUI, as long as you don't need 4G, everything else works and it's extremely stable. Other than a few times trying other ROMs, I've been using it as a Daily since June

Thank you for your answers. I have some follow up questions:
1)

What is the quickest way to use terminal? Do I need the dev tools on my computer and put the phone in debug mode?
Where is the Dalvik Cache normally stored? I thought it was on RAM. Since it is a cache, I would expect that it changes often. Is it not going to wear out the sd card quickly?
2) The point is that I want to save also some system settings (ex: remembered password of wifis, browser history, sync settings, etc). Last backup save 203 items. It is going to be a pain to go thought one by one.
4) I looked at MIUI but I ruled it out because it does not support 4G. I use it every now and then.
Like you I was having some problems with my rooted stock (low phone memory, slow and some other performance issues).
I downloaded ROM Manager and then made a backup of my rooted stock. You can also do it manually by booting into recovery but ROM Manager is easier though some people will say is more prone to errors. Also download Titanium Backup or something similar and save all of the apps (both download and system apps).
Once I backed up my rooted stock ROM I then downloaded and installed the latest Cyanogenmod. As this does not have HTC Sense or bloatware I immediately got a significant amount of free space that handles all that I load.
One thing with Cyanogenmod 7.1, some people like myself will have freezing issues if you have less than 130 MB of free space on the phone. This is not a problem for me as I have more than that available. I chose Cyanogoenmod ROM over MIUI ROM as Cyanogenmod allows for 4G. Take a look though at all of the ROMs out there and decide for yourself.
I find that everything is running faster now and I no longer have the Bloat that Sprint put on the phone. You can also move more apps over to the SD Card freeing up more internal memory.
Apps like Flash and Adobe Reader can be downloaded from the Market and are updated just like any other app.
Good luck
Uhh, no to ROM Manager. It's known to cause problems.
The Terminal is an app. You use it on your phone.
AS for system settings, only a very few can be successfully moved from ROM to ROM. The only thing I backup is my Alarms. You don't have to do them one at a time, you know. Hit Menu, Batch and then you can do them en masse
Depending on how many apps you load on your phone you may want to re-partition your SD card if you have the space and create a 1-2 gig ext2 or ext3 partition to use for apps2sd. The main reason I rooted my EVO was because I constantly kept running out of space on my phone. I'm an app addict though and have been known to have up to 200+ apps on my phone before I re-flash it with another rom. With a 1.5 gig partition and apps2d, I have never run out of space for apps on my phone though If you do decide to re-partition your SD card you will need to completely backup your SD card to your PC first as it will wipe all data on the card. I have a 16 gig class 10card in my EVO and the speed is pretty good.
i would give energy sensation a go, i was using that rom as my daily it is really staple, great battery life and improves the video recording to 1080p HD as well as plenty of other little tweaks here and there....I am running ics-decks-pre-alpha7 which i am really liking only thing is you would have to be willing to give up your camera til a stable alpha or beta is released. I hope this helps...
I have been running the Sprint Updated 2.0 Final for a few weeks (see http://forum.xda-developers.com/showthread.php?p=20631581 ). I also re-partition my SD card with 1.5Gb (if I remember well). So far everything is good except:
1) I have 99Mb free on the phone. I think the main reason is that I disinstall some of the Sprint Bloatware and haven't reinstall all the apps. However I started having problems when I had 60Mb available before the upgrade to this new ROM. So I am afraid that I am getting close :-/
2) Wifi Tether has problems. I am experience the problem here: http://code.google.com/p/android-wifi-tether/issues/detail?id=1288 .
The workaround with Barnacle alleviate the problem but beside being annoying that I have to start Bernacle first and then the Wi-Fi tether, it sometimes stop working (I think it is when I I use the 4G and the 4g connection is lost) and I have to go though the cycle again :-/

If u want AOSP evo-deck-(gingerbread 2.3.7) only takes up 13mb of internal on initial boot 19mb after flashing gapps and its really stable too u might have to fix gps but thats the only issue i ran into (which is just a flashable zip if you do have to) and you can move the majority of apps to sd like CM it has a allow move to external option.

How to keep a ROM Fast??

I am trying to find out what house keeping should be done to keep a rom fast? This question is not directed to a specific rom, but memory management in general.
I flash a rom, and it runs good. After a day or so [if I keep one that long ] I notice that it starts to slow down. Some times I select a new rom to flash because it is interesting. Other times I select a new rom to flash because the one I am using is slowing down.
If I look at the memory in Titanium Backup, it shows that either or both the system rom memory and internal are getting towards full.
I am using a2sd and it shows some memory used there.
I guess my question is, do we simply need to clear the cache every couple of days, or is there more necessary?,
I appreciate any and all suggestions as how to keep the EVO 4G running faster.
I would clear app cache every couple days. I also reboot at the end of every day. Clear cache and dalvik in recovery one a week or so. I notice this happening with my evo as well. Its not as bad on my rezound though. Probably something to do with free space.
Sent from my ADR6425LVW using Tapatalk 2
I agree that clearing cache and rebooting is very helpful. I also use a2sd, dark tremors, and I have noticed that the more free system rom I have the smoother and faster my phone is. I used to use my a2sd to move dalvik to the sd card, now I move the dalvik to the "cache" partition and it seems to run better that way too. I noticed with the dalvik on the sd-ext it would take much longer to wipe and it seemed like I would get random errors... Could be coincidence, but the way I set up my rom's with the a2sd I typically have 100mb+ free in my system rom so its not an issue to keep the dalvik internal. I'm not really an expert but I have had my evo for about 2 years and I have flashed and set up my phone a ton of different ways and a2sd is a must with the evo. I noticed a big difference in smoothness since paying attention to my free internal space. I also have a bricked evo with a spare battery, so I shut my phone down daily for the battery swap. Prior to that I would never turn my phone off or reboot, and since I do it daily it seems I have had less issues.
Sorry for the giant rant, but hopefully I gave you something from all that
I use cache cleaner every morning and each of my Roms gets CoD tweaks added. My stuff runs buttery smooth.
Sent from my Blazin Fast Reloaded. 44
Also try to use odex roms as they are faster than deodexed... and if the rom you like isnt odexed then try to odex it. Not hard just need JRE and dsixdas kitchen then unpack the boot.img and find the bootclasspath i think its in ramdisk somehwhere.

Best optimizations for GNex

I seem to have exhausted all my self help efforts so I'll turn to the general populace for input.
My Galaxy Nexus GSM is running the deodexed Google ROM 4.1.1. Its unlocked and rooted (of course). I have been finding lately that the device is becoming slow at times, and even occasionally locks. I have had a variety of applications on it to 'optimize' but I have found that really does not do too much but add more clutter and 'crap-ware' to the device.
What I want to know are some examples of ROM+Utilities that people use to keep the device running fast and error free. I'll load a different ROM and utility 'recipe' to smooth this thing out.
Any examples/ideas from the tinkering experts out there?
I usually boot into recovery and clean cache and dalvik about once a week. It helps a lot.
If you want to expand on that, do a scheduled daily TB around 5 or 6am each day and a monthly factory reset with restore from one of those dailies.
Android seems to have a tendency to get slower over time, depending how much apps you have installed (I have about 260) and this procedure mitigates on those issues.
Sent from my Galaxy Nexus using Tapatalk 2
Well what kind of "optimizing" apps did you use? I hope it's not task killer
Monthly factory reset? I'm gonna say that's really excessive.....I don't do any of those and I never have android getting slower over time.....you'll get the same effect by rebooting the phone.....
Sent from my Galaxy Nexus using xda premium
a reboot at least once a week is good...
also, clean the cache every once in a while...
i reboot every other day.
and also clean cache and dalvik cache every other week.
Use app called System Tuner, grab from playstore. Its free. It does everything already posted and more. Best of all yoyr battery will thank you

[Q] Are the relatively newer ROMS too heavy for Desire Z ?

Hi guys,
I have question regarding my HTC Desire Z .. Ever since I rooted the phone about 1.5 years ago, and have been trying out the newer ROMs, I've slowly realized that my phone is getting slower, slower, and slower .. I'm currently using a Jellybean ROM, and its *extremely* slow ! I mean, at times I receive a call, and the ringer rings about 5-6 times, and during all this time, the phone doesn't have the juice to switch to the phone app, so that I can 'accept' the call ! Ultimately the call disconnects itself!
A friend recently suggested to me that maybe the newer ROMs are two powerful for my phone, and that I need to move to an older Android version ROM, which my Desire Z CAN handle, without this much lag !
Also, I hardly have any apps installed on my phone at all, in an attempt to keep the load low .. I also use 'Advance Task Killer' regularly to kill background apps, but it doesn't really improve anything ..
What can I do to improve the speed of my phone !? I really pisses me off to see a 10-15 second lag when I call someone !
Get rid of the task killer first of all...

I dont think it will make any difference .. I've tried many different ROMs, and its always the same condition with all ... Sometimes my phone become *so* unresponsive that I just feel like smashing it on the ground ! (When I really get upset!)
Also, on another note, when I open Advanced Task Killer, it shows me the amount of free RAM on the top .. Most of the times this value is between 60 MB ~ 100 MB, and sometimes between 100 MB ~ 140 MB .. If never seen this value go above 135 MB or so ... And Desire Z is supposed to have 512 MB of RAM
just full wipe and reflash the rom

If I do that, it will initially be fast .. Even if I install all my apps on the first day, it will still be okay in terms of speed ... But give it a week, it eventually becomes slow .. very slow! .. And the odd thing is, during this week, I don't necessary install/uninstall anything .. the phone just ****s itself in somehow ... And then from then on, it remains slow, no matter what ...
I open Google Maps, takes like 15 seconds to open .. takes another 60 seconds to go to Google Navigation, and then further lags after that ..
Basically there's a lag in *everything* !
Is there a way I can see what is slowing down the phone ?!
Also, is it true or not whether an older phone, such as Desire Z, can or cannot handle a relatively newer Android version ROM ? Maybe this is why the latest Android versions are NOT officially available for phones many times, because the manufacturer knows the device cannot handle that newer Android version ?
If your rom supports ext partitions, make sure all of yours are formatted that way. Chances are you have sopme bad apps, a logcat may hedlp determin abused wake locks or memory leaks. Also you can try downloading battery batt stats or watchdog for more infor

i had a play with elitemod ics the other day & it was defiantly slower than the GB version... it was using more or less double the ram which i suspect is the real problem.....
Yes its true the newer versions are more hungry. We touched on it in one of the andromadus threads recently. I believe the issue to be the cpu. The nexus s has the same amount of ram as us and although its not as good on there as the gnex, its still good. Having bumped my lower cpu limit a notch, its much better. I also tried a few upper limits and found that 1200 to be best as it suffers with animation under that.
But then all dz's are different. Stay on your rom and bump up the lower limits a few clicks and let us know what you think.

I've noticed the slowdowns happening with negligible CPU load and no memory constraints. I suspect a problem with the kernel. At the times it happens, the phone seems to be just doing *nothing*.

Is there any other thing I can try apart from logcat ? I installed Watchdog a few hours ago, but so far it hasn't reported anything out of the way ..
What does have ext partitions do ? How does that speed up the OS ?
Also, I'm probably going to be re-flashing another ROM soon, so please suggest me a ROM ... I'm looking for maximum longterm stability and responsiveness here, so even if a ROM isn't the newest or the most feature-filled, I can still try it out ..
And what is Superwipe (read it in another thread) ?
Normally, when I restore stuff after installing a ROM, I download a fresh copy of the app from the Store, and only restore the app's data using titanium .. is this okay ?
For the sake of starting fresh, flash the ext 4 recovery and flash mimicry as your rom. Read all suggestions in the first few post on mimicry, to flash 4ext I made a thread, you'll find it the first page or so in the general section (dzhboot or something)
Mimicry is one of the best made best performing full featured ics roms for our phones, partitioning everything to 4ext (easily done through recovery) will make it far better. Other bonus tweaks will be added in.
There (in my opinion) are beter performing gingerbread roms, but I do sugest mimicry as it is amazing and the dev has laid out a wealth of knowledge in the first few posts

Well this is the ROM I'm currently using, which I flashed about 2 months ago, which is giving me all these performance issues ..
I went through the first few pages, but I didn't find any instructions on 4EXT ... The only thing I found was in the OP's FAQ in the start, which said that you should apply ext by downloading 4ext from Play Store, if you get lags ..
Anywhere else I can look ?
Look in general section, somewhere in the first page I posted a thread called dzhboot on g2 or something to that extent, one of the first few posts I eplain how to flash 4ext recovery.
One of the fastest roms I have used is elitemod cm7, maybe try that

I have been wondering the same as the OP. I have been using andromadus and andromadus mimicry roms for the past few month. I tired cm9 unofficial but it was no different to mimicry in terms of lag. Currently on flinny's jb beta http://forum.xda-developers.com/showthread.php?t=2005136. Lag is not terrible but too often I am looking at a white screen waiting for something to happen.
I often experience lags opening apps like phone and browser (any browser). Phone hanging when trying to make a call is particularly annoying because my wife asks "why is your phone so ****?"
I would love to have a really smooth experience like others report but even with a fresh wipe I seem to have trouble. When I try to reduce the process limit i still seem to have too many processes running. What should i look for in logcat in terms of tracking down the problem?
Maybe 4ext will sort it out? I am very loathe to go back to a cm7 rom.
Ext4 worked really well for me to speed up my phone.. I highly recommend it.

It's gotta be a certain app your installing thats hogging all your memory, I been running mimicry ever since blk released it n have had very few slowdowns.
Never had a problem receiving/making calls 'wiping' is not the same as 'superwiping' its different then just the name, I suggest you do some reading up before flashing any more roms.

i superwipe, and i've been flashing roms since the g1. I am not seeing any particular process hogging resources. this current jb beta is pretty good but still get some lagging at random.
if that were the case I would love to try and find out what it is.
it seems to me that a minority of users report lags in rom threads and are dismissed without ever really getting to the root of the problem.
I would really like to try and get to the bottom of it. I am going to move to ext4 but if there are other troubleshooting steps to take I am all ears.
Ext4 alone will make a huge difference, and most of the rest of the slow downs will be do to apps/running services which can be seen with a logcat what is continually trying to use cpu resources
If only a minority report slowdowns then either that minority has a different idea of how the phone should run/ they use the phone in a completley different way/ or have different settings and apps then most have.

[Q] Memory leak all roms android 4.2.2

Hello,
Come some time testing many custom roms of Android 4.2.2 for the Galaxy Nexus in search of some that actually have a good performance without lags, with a good battery life and better without memory leaks.
I have tested Cyanogenmod 10.1, XenonHD, AOKP, Xylon, SlimBean, LiquidSmooth, ect. Also tested some variations of kernels (the best result was with FancyKernel r33). But all roms have this "memory bug" of Android 4.2.2.
I researched a lot about it, but found nothing very relevant or a potential solution.
Well, I came here just to share my experience, if someone has a solution or a suggestion and also want to share your experience, comments.
Did u try purity 5.7 ??
With fancy kernel r33 i get pretty decent free ram ( almost never under 100 mb...) I have also used aokp, paranoidandroid, revolution HD, jellybeer and stock. There is none (for me- from those i tried) better than this... Smooth, simple, buttery
My advice - give it a try it's worth it!

Define 'memory leak' for us. For example, I often have so many apps saying xMB, and when combined together, including running services, they do not add up to the total amount of ram used. Is this what you mean by a 'memory leak'?

For now, i'm running stock 4.2.2 and Fancy Kernel r33. I do like all custom Roms, but for this moment, this combination is great.
About Memory leak, the 4.2.2 have this known bug. After reboot works fine, but after open & close several apps, the memory is still full and the lags start.
Isn't a problem with the custom Roms, but with the Android 4.2+ source code.
But this is the reason why I opened this thread, so that we could discuss about this and shared our experiences.

I'm using the latest RasSaber (4.2.2) for Toroplus, with Franco.kernel r382 and scripts installed for a 300MB swap file in /cache. The best part about running a swap file is that the /cache partition on our phones is unused, so you don't lose any useful space with it, and you can use it on any ROM, with any kernel as long as the kernel supports swap.
It's so much smoother than without it; I used to run @ 1420mhz and still have lags, now I don't run an overclock at all and it's perfectly smooth.

What script are you using for the swap file? It will be great if you can point us to the link for the script.

Hello,
Come some time testing many custom roms of Android 4.2.2 for the Galaxy Nexus in search of some that actually have a good performance without lags, with a good battery life and better without memory leaks.
I have tested Cyanogenmod 10.1, XenonHD, AOKP, Xylon, SlimBean, LiquidSmooth, ect. Also tested some variations of kernels (the best result was with FancyKernel r33). But all roms have this "memory bug" of Android 4.2.2.
I researched a lot about it, but found nothing very relevant or a potential solution.

Yeah - already posted the very same question here at XDA. I recently tried CM10.1 stable and nightly, Root-Box and Paranoid 3.60. All the same: after some days but not more than a week the "free RAM" drops to about 100MB and phone starts to become very laggy so I have to reboot to get back to 250-300MB free RAM. Mind: free RAM includes cached applications and is still considered by Android-OS as "free" which makes sense because it can be allocated at any time to new applications. Low free RAM results in no more cached apps which will make your phone slow at starting up new apps because android has to fight for every "bit" needed by the starting app.
I also tried recently to revert back to cm9 (android 4.0.4) and found out that this OS is very very stable in terms of RAM usage. Even after a week I had the very same amount of free RAM as after rebooting. Give it a try if you don't need the extras in 4.2.2 like lockscreen widgets.

No, not yet tested Purity Rom. But I noted here, and when some time left over I will test.
In this moment, I'm satisfaction with Stock 4.2.2 and Fancy Kernel. This kernel is awesome. Really smooth, fast and battery friendly. The ram optimizations is really great.
But the search continues. :fingers-crossed:

The GSM GNex is supported by the Aroma installer, so users of that phone should be able to install as described in the thread.
All credit goes to delta-roh and Harbir, I am merely a supporter of their work.

The GSM GNex is supported by the Aroma installer, so users of that phone should be able to install as described in the thread. Toro and Toroplus are not supported, so we have to install the scripts manually, which I will explain how to do here in order to avoid making you guys search for instructions:
0. Your kernel needs to support swap, or this isn't going to work. I don't know which kernels do or don't, you'd need to discuss that with your kernel's developer.
1. Download the turbo-boost.zip from the thread above.
2. Once you download the .zip, you'll need to extract the script for the location and size of the swap file you want. For instance, if you wanted a 300MB file in /cache, you need to extract swap/cache/300/etc/init.d/98swap_cache_v300 (all the script files are named 98swap_(location)_v300, so try not to get them mixed up!)
2.5. I recommend using /cache as the location for your swap file, because as I stated above, /cache is an unused partition in newer versions of Android. On my phone, /cache was a 425MB partition of completely empty space.
3. Copy the 98swap_cache(or system,data)_v300 script file to your phone.
4. Move the script file to /system/etc/init.d
5. Set permissions to rwxrwxr-x (chmod 775)
6. Reboot. If the swap file is working, you should have a swap_xxx.log file in /data/swap, and you should notice more free RAM and a smoother phone!
Side note: Root explorer makes steps 4 and 5 ridiculously easy. I ran into some trouble trying to chmod using terminal emulator.

Thanks for this tip! I installed this mod with stock ROM and FancyKernel and this combination is REALLY AWESOME!
I install about 3 hours and no some lags even with so many apps opened! The performance is the same that 4.1.2 (for now).
I want more test some days for confirm this great result.
But, thanks so much for this tip!

Fancykernel r35 and skock 4.2.2 is really smooth! I'm felling 4.1.2 times again!

I have cm10.1 and have lag on tapping something in settings. I tested that lag appears every third time I tap on some setting. This is very annoying and have no idea how to fix. It's not a cyanogen or aosp bug, it's 4.2.2 source code and this android is made by developer's legs...
