In my case, I'm experiencing terrible slowdowns, even in lockscreen. Sometimes I have to remove the battery because the phone becomes unbearably unresponsive, and I have nothing but tapatalk installed (with notifications disabled). I don't know what is happening, I never saw slowdowns this bad before. I already wiped the phone twice, removed microsd card, nothing solves.

I don't know if I'm doing anything wrong, but I'm trying to replace system (feav's like) camera with Jishnu Sur camera and whenever I reboot, the old camera comes back.

Since I understand almost nothing, I think this has something to do with cache...
[LG Optimus 2x] Frecciablu(2):
U should delete it with root browser

Then put there the camera u want in system and gv right permission.

(Delete it easy worked to me)

[LG Optimus 2x] yankhor:
yeah, it worked.

to be honest, I did this before, but I didn't replace the apk in the system/app, I just created another apk and after the click, it installed the new version, which disappeared after the reboot. :eek:

this time I replaced the feavCamera.apk with the other app and it survived the reboot :laugh:

[LG Optimus 2x] messi_007:
Thanks tonyp I can confirm your latest RIL baseband fix working great :)

I just noticed External SD card mount and unmount works amazing.Hatts off for this Fix too!!!

Build-cm-11-20150218-m1-p990

Issue:

1.Gmail still has issues with google play service error :( however I could manage to get this working with older gmail version 4.7.2

2.Soft reboot works great but after reboot it doesnt detect network provider.

3.Normal reboot takes more than 70 seconds.It will be great if this time could be reduced just like quick reboot

4.Wifi tethering works however unable to set pwd,still unable to set password in wifi tethering set up.

5.Google play news giving error "couldn't authenticate your account"

This is strange,We should be able to use it as we are able to use youtube flawlessly.

6.About phone->Change log still showing it as CM11 M11,I thought its CM11,M12 code base!

7.Can someone please enable double tap to wake up device just like 3.1? its just amazing feature!

Well thanks to Tonyp and all Devs for your great work,if you get time please try to fix above mentioned few issues.No ETA required!
[LG Optimus 2x] tonyp:
Thansk for the confirmation! I'm glad those automatic time detection is finally fully working.

As you can see here, some dedicated research - in this case the great [MENTION=5399879]echo_21[/MENTION] - can go a long way as he tracked down the culprit, a misread baseband read.

That's what a development community is for.

Yup I fixed the SD card mounting too, it was just a missing configuration but it took me some time to track down it's culprit.

Regarding your issues.

No idea, maybe Google ****ed up again and is shipping some incompatible apps to our device (like Google Maps or YouTube in the past)?

You could try to flash some Kitkat gapps packages out there just in case it's caused by the included gapps. If so I'll update it.

Yup it's the old bug where the radio doesn't get properly reinitiated, same as after coming from the airplane mode.

Sometimes double tapping data (disable/enable) helps, sometimes not.

But in general I wouldn't recommend to use the soft reboot option anyways. It's good for development as the ROM restarts faster, but it can cause some instabilities so it's not recommended for everyday use

There can't be done much here. You could disable/remove the bootanimation which might reduce it a little bit (but you'll have to ask Google about the details)

Yes, it is based on the newest stable/cm-11.0 branches which incorporate M12.

M12 announcement post: http://www.cyanogenmod.org/blog/cyanogenmod-11-m12

Cyanogenmod seems to make a habit of forgetting to update the included changelog.

Stable changelog (up to M11): https://github.com/CyanogenMod/android_vendor_cm/blob/stable/cm-11.0/CHANGELOG.mkdn

M12 Changelog (not merged to the stable branch): https://github.com/CyanogenMod/android_vendor_cm/blob/cm-11.0/CHANGELOG.mkdn[/strike]

M13 should be the last CM11 release, but they didn't post any timeline for it's release.

See 1.

I highly doubt you'll find another kernel developer who would take on that task for this old device, but you never know.
[LG Optimus 2x] Slowdeath:
Hi messi_007,

Regarding problems with Gmail and Google play news try to install newer "Google Play Services". I installed version 6.6.03 and everything is fine now.

I see that there is already newer version in this thread: http://xdaforums.com/android/apps-games/app-google-play-services-t2795911

You can try it.
[LG Optimus 2x] Surplus:
I believe it is caused by gapps. For me inbox and google play music stopped working properly after flashing the newest update. Both apps were on the latest version before updating as well.

I will also note that clean flashed M1 instead of 3.1, which I used before, so that could also cause issues, but it should be unlikely.

I am currently updating Google Play Services to see if that fixes anything.

EDIT: Updated Google Play Services. Phone seems less sluggish, no longer freezes when trying to play music with Google Play Music. Free RAM is around 160mb to 120mb(both w/ greenify and google services running in background). I will be testing this further to see if performance downgrades in a while.

EDIT2: After a few hours of usage peformance has not decreased and no problems with gapps. Things only slowed down when play store started updating apps. Free RAM peaked at 174mb, but typically is around 140mb. Only problem I experienced was getting no cellular coverage, which I solved by turning off and on the radio in the test menu. Next time this happens I will try to grab logcats, but if nobody else has this issue, I would presume it's due to water damage my phone has suffered.

The gapps I installed were from here: http://xdaforums.com/android/apps-games/app-google-play-services-t2795911

I doubt that Google Now uses NEON instructions because I cannot find any SIGILL message in logcat after it crashe. According to [MENTION=3605868]tonyp[/MENTION] 's NEON post there should be SIGILL messages in this case.

Which kernel do you use? Under CM11 kernel 2.6 M1 I have very good experience with ported LG camera 2.4.124 that gucky01 ships with his most recent CM11 build . AFAI remember it does not work under kernel 3.1.

Kernel 2.6 M1 assumed, download the ZIP file, extract camera apk and install it.

Uups, I am sorry: I just saw that gucky01 removed all the CM11 ZIP files...

[MENTION=5021221]gucky01[/MENTION] would you like to supply a link where to download ported LG camera 2.4.124 apk ?
[LG Optimus 2x] NoDze:
As far as I know, feav's ported JB Camera works amazingly well. Just make sure to download the test1 CM10.1 zip and flash it in recovery. Other than that I've had a fun experience with Open Camera. :D

I'm using Firtecy kernel and both Feav camera and Open camera crashed.

Beside cyanogen camera, HDR Snap Camera works well too, maybe works better than cyanogen camera. The trial version is free, you can download it from play store. Only limitation is 10 seconds delay (or 5 seconds delay i forgot) when connected to internet.

[LG Optimus 2x] CalculatedRisk:
Hello everyone,

I recently installed the latest CM11 on my P990 and for the most part it works well, however, I do see some slowdown issues and stutters which I believe is the result of the device's low ram. I am using Firtecy Kernel exp 5 (3.1) with 32 mb ram hack (370mb Ram total), and have greenified most apps. I also have purged assets enabled and have set the memory management option in Kernel manager to "Medium" which has helped a little. I have also taken control of what is running in the background of the system. Is there anything else I can do to maximize performance? Thanks in advance.

[LG Optimus 2x] echo_21:
Make sure (P)KSM is running. Note: PKSM implements KSM under kernel 3.1. What is the contents of /sys/kernel/mm/pksm/run ? This has to be 1

What is the contents of /sys/kernel/mm/pksm/full_scans? If this is less than 3 you have to wait a while. With default settings (P)KSM needs several hours to work properly (i.e. the value >3).

What is the contents of /sys/kernel/mm/pksm/pages_shared ? If this is less than say 500 (P)KSM does not work as it should.

Without proper function of KSM IMHO our low RAM P990 won't work with acceptable performance (for definition of this term read this post).
[LG Optimus 2x] salmanfarisy:
Is PKSM enabled by default? How to enable/disable it? How to configure PKSM?

Edit:

Btw, my /sys/kernel/mm/pksm/run content is 0. So, is PKSM disabled in my device? But i don't feel any slow down on performance since i flashed the rom at the end of January. I'm really happy with my p990's performance.

Kernel is Firtecy 3.1.10 Exp #8, and Rom is CM 11 20150130.

[LG Optimus 2x] CalculatedRisk:
Hey,

I just checked the values after a fresh boot and these are the results:

Run: 1

Full_scans: 0

Pages_shared: 727

Both run and pages shared produce optimal results, however, full scans seems to be below normal. This is a fresh boot, so I will give it several hours, test again, and report back, as per your suggestion. Thanks.
[LG Optimus 2x] CalculatedRisk:
Okay, it has been quite a while running the device, and after checking the full_scans value again, it remains at 0 and so I'm not sure what that means. Is there a way to restart the service to get it functional? Thanks a lot for your help.
[LG Optimus 2x] echo_21:
I am on CM11 under kernel 2.6 at the moment and I didn't use CM10.2 or CM11 under kernel 3.1 very often. From what you write it seems to me that PKSM (under kernel 3.1) works a little different compared to KSM (under kernel 2.6 M1): under kernel 2.6 M1 /sys/kernel/mm/ksm/full_scans (note the missing p in front of ksm) is being incremented by 1 every once in a while. Under 3.1 /sys/kernel/mm/pksm/full_scans seems to stay at zero.

Anyway I believe that (P)KSM effectively saves you a lot of RAM as you wrote that /sys/kernel/mm/pksm/pages_shared is 727. You can calculate how many Bytes of RAM is saved. Let's assume that /sys/kernel/mm/pksm/pages_sharing is 3000 (please check up-to-date numbers on your P990 again). Then the RAM saving IMHO is 3000-727 = 2273 pages. One page is 4096 Bytes. So you'd save 8.8 MB.

As you wrote that /sys/kernel/mm/pksm/pages_shared is 727 even a short after a re-boot, I believe that PKSM somehow works much faster than KSM. With KSM it takes e.g. one hour to get e.g. /sys/kernel/mm/ksm/pages_shared=500. KSM seems to finished it's 3rd cycle after that long time as /sys/kernel/mm/ksm/full_scans=3 then.

Summary: I believe that PKSM is running effectively on your P990. I believe that PKSM saves RAM much eralier after reboot than KSM under 2.6 M1 does. I believe that PKSM on P990 kernel 3.1 does not increment /sys/kernel/mm/pksm/full_scans . Be happy with the latter...

Bad news is that you suffer from slow-downs even if PKSM is running. I used to believe that well running (P)KSM is required for lag free operation. Now we have this report from [MENTION=6332575]salmanfarisy[/MENTION]

that says that PKSM is not running on his CM11 under kernel 3.1 and he doesn't see any slow-downs. Now one could speculate that the particular PKSM implementation could be responsible for observed slow-downs. I would recommend to test if disabling PKSM removes the lag. Thus you, [MENTION=5077705]lolcakes203[/MENTION], would have to set /sys/kernel/mm/pksm/run to 0. Is there a System settings|Peformance|KSM check-box to do so? If not, I don't now exactly how to do this easily. Probably you have to add a command line to an init script then.

For those readers who have a P990 under 2.6 this it is very easy to disable KSM for tests unsing the corresponding setting in Performance Control app.
[LG Optimus 2x] CalculatedRisk:
Thank you very much echo, I will research and try to disable pksm for testing. However, at this point, I do believe my slowdowns and stutters are the result of simply pushing the device too far. Thanks again, I will report back with my findings.

From some time I have a strange problem with CM11. The phone don't go into deep sleep. I've never suffer such problem before. I don't know what is the cause of the problem because I made full wipe and tried to install also couple of older CM11 roms. Also tried 3.1 and m1 versions. Different kernels RH and no RH. Tried to uninstall updates of google play services. No success. The only workaround is to enable SystemUpdateService of Googleplayservices. But I have to do this manually after every reboot.

Anyone has an idea which may cause this. Tony's CM11 rom worked great before couple of weeks.
[LG Optimus 2x] siuk_:
Strange, never had the problem of deep sleep.

I have tried almost all the ROM and the best (in my opinion) is the cm-11-20140918-UNOFFICIAL-p990-m1-GCC4.8.zip https://basketbuild.com/devs/gucky01/P990/CM11/Tonys always installed with full (to advance wipe all boxes except external SD).

But lately I have had battery drain problems because of google play service.

I solved it by going to settings -> privacy -> privacy guard and long press on Contacts (select everything on denied), Contacts google sin..... (select everything on denied), Google play service (select everything on denied), Google Service Fra......(select everything on denied).

These settings remain in effect after a reboot.

The rom works fine, the only app that crash is Shazaam.
