Battery drain for me too, but no other trouble noticed
[LG Optimus 4X HD] vieri_202:
2 issues for me

1- when someone calls me and im already on a call. I stop hearing anything

2-too many apps fc

I did a clean install
[LG Optimus 4X HD] lorddimic:
New theme engine is very buggy, I tried few themes that are supported by new theme engine but they didn't run as it should. Lot of FC, lot of strange slow down... I hope they fix it soon, at least there are commits about themes on every nightly.

Cheers

Nightly 18/06/2014

working fine again :laugh: and even faster.

Just one question: what is CMHome.apk? :eek:
[LG Optimus 4X HD] dimi89:
I am using 14th build everything works fine HD videos dont lagg just tryed in youtube (if that is what u ment).
[LG Optimus 4X HD] aria12:
No service. ? Battery drains like hell.I'm on last nightly.

Log: https://www.dropbox.com/s/fylfaim2uhvtlla/2014-06-19_20.20.zip

Edit: format system and flashed the ROM again.Problem solved.
[LG Optimus 4X HD] Navios92:
Can I use ART with this ROM or is it unstable? Does changing the kernel to iodak affect it?
[LG Optimus 4X HD] aria12:
Next nightly will be base android 4.4.4 .?
[LG Optimus 4X HD] ruznik:
Why this issue is not fixed ?

I'm facing this issue since i install first version of CM 11 , when screen orientation is auto there is glitches after screen off and on
[LG Optimus 4X HD] PenguinStyle:
WTF? 4.4.4? How? there is no version like this
[LG Optimus 4X HD] aria12:
look here :http://changelog.bbqdroid.org/#/p880/next
[LG Optimus 4X HD] PenguinStyle:
What about this : http://www.cmxlog.com/11/p880/
[LG Optimus 4X HD] wilson3q:
[MENTION=4686233]aria12[/MENTION] is right! From the graph, CM11 next nightly is after the 19th nightly 22:58.
[LG Optimus 4X HD] KrisJoe:
I finally managed to have a clean install with cm11 19th June, with new gApps downloaded from cyanogenmod's site and iodak v10beta, but it was so laggy that I couldn't bear it anymore and installed iodak v9.95. I don't know why it happened because before the full wipe iodak v10beta worked very well.

I hope I won't have signal losses again..!
[LG Optimus 4X HD] dimi89:
For 10000000000000 time already..Try first clean install with stock kernel then when u make shure everything is fine with rom flash custom kernel that u want and tweak it.I am saying this because we cant help you since you didnt provide log also your bug report is unusable since you are not using stock kernel so any of your "reported" bugs could be custom kernel related not rom itself.

Послато са LG-P880 уз помоћ Тапатока
[LG Optimus 4X HD] KrisJoe:
For now it seems I'm not having signal losses where I usually had, and it's getting better, I just deactivated google Now and it seems a bit smoother.

I can finally try ART again since with signal losses I had to restart the smartphone so many times I would have lost nearly 10 minutes every reboot.

Small graphical crash when screen orientation this automatically appears after screen on & off

nice work in this rom, thanks
[LG Optimus 4X HD] bilbo75:
[MENTION=1149134]Demetris[/MENTION] I've just installed the build 080814 and I've checked /system/etc/gps.conf and doesn't look the file that you pushed in the latest commits

Am I wrong?

By the way, before install I've formatted /system and wiped cache and dalvik.
[LG Optimus 4X HD] musklor:
New roms are not available under cyandelta (20140806 for example)
[LG Optimus 4X HD] maderos:

[LG Optimus 4X HD] Demetris:
Fixed :)

Thanks for the report. :good:
[LG Optimus 4X HD] dimi89:
This fix will be in tomorows build ?
[LG Optimus 4X HD] Demetris:
If we get one, yeap. :good:
[LG Optimus 4X HD] playitlouder:
Hi,

I thought I give CM on the 4x HD another try. My stock rom was acting up (slowdowns, freezes, etc.).

I tired unoffical CM back in march or so, but it wasn't quite usable (radio bugs, no video cam etc.).

As this is my main phone, I tried official CM this time.

Well, it works ;)

But it has some hickups, too :D

Do others also experience glitchiness in general? Like slowdowns and not reacting to button presses immediately?

I tried fiddling around with governors which has not made a huge difference, but changing the govenor from BFQ to deadline has increased (game) performance quite a bit!

Maybe there are other tricks to get some more smoothness (especially scrolling trough stuff is stuttery at first eg. WhatsApp history)...

EDIT: It seems like these mini slowdowns are affecting all apps, even poweramp playing music in the background stutters while surfing http://boston.com/bigpicture (intensive website)
[LG Optimus 4X HD] ssefrgr:
Well I tried to load this intensive site and the phone managed it really smooth even with just 3G, scrolled up and down, zoomed in and out without any problems. Using 08-08 build with no changes or tweaks. BaNks minimal core-gapps and no ART.
[LG Optimus 4X HD] EB20XY:
All fine with 0808 build +1
[LG Optimus 4X HD] Navios92:
I tried 0808 build and the rom was slow since the setup wizard. Slow response, scrolling, app opening, etc. I don't know whats causing this but it's been like this with every build. OMNI rom on the other side is extremely smooth.
[LG Optimus 4X HD] maderos:
Use custom kernel. Stock cm kernel is useless ( for me ). But rom itself is ok. So far working great.
[LG Optimus 4X HD] EB20XY:
I use nightly from 8.8. from here http://beta.download.cyanogenmod.org/get/p880-latest.zip

And for me it is working smooth and fast sofar. Also very low battery drain over night and during data usage and calls.

My combination is in the footer ...

Great!
[LG Optimus 4X HD] playitlouder:
Which custom kernel should I try? Link would be awesome :D
[LG Optimus 4X HD] EB20XY:
Did you used nightly from 8.8. ?

Cause only in that version are the fixes against the lags and "hicks" included.

For me it works perfect, so it should be not very likely that it will work totally different for you ...
[LG Optimus 4X HD] maderos:
I got latest nightly. Tried with stock cm and custom kernel. Custom beats stock easly. So, custom kernel, maybe is ok, but not for me. It feels not smooth, responsive, ect.
[LG Optimus 4X HD] playitlouder:
I am using the 0808 nightly. But compared to my Nexus 5 its super slow and not smooth. The phone sometimes needs some seconds to think about stuff like waking up from sleep or general user interface stuff. It just does not react instantaneously every time. Sometimes it is quite good, but not all the time.

Could you please tell me WHICH custom kernel you are using? So I can try it out :D
[LG Optimus 4X HD] maderos:
Continuation of iodak's work. I cant copy link here.
[LG Optimus 4X HD] playitlouder:
I will give this a try now http://www.modaco.com/topic/373059-continuation-of-iodaks-excellent-work-kernel-updated-14-08-01/
[LG Optimus 4X HD] dimi89:
You must be trolling right ? Nexus 5 have KK update not to mention other stuff that are vital for rom performance.it is act of art what developers managed to make and do for this phone.Also it depends on rom itself thats why we have Omni + liquid (my favorite) + unofficial CM11 + beanstalk + a lot of others (dont want to point each specific or let someone out but all roms are great and working good for me it just choice what whould user prefer more-customization over simplicity).
[LG Optimus 4X HD] Demetris:
I tweaked bfq to handle better NAND flash memory-based storage devices.

Am testing it now and if all goes well i"ll push it asap.

So you know anything you report is taken under consideration *if possible and we do our best to please your demands.

But this kernel is mainline and we"ll keep it this way.
[LG Optimus 4X HD] EB20XY:
Is it possible to include the commits for fast-charge into the kernel ?
[LG Optimus 4X HD] playitlouder:
I dont wanna troll :D Sorry!

I know the graphics driver situation on the 4x HD is not optimal, and my nexus is the faster device.

The other kernel I tried fixed the lagging issues for me.

[MENTION=1149134]Demetris[/MENTION] could you please take a look into memory management? I think something is bugged there. When i do a couple of things, like downloading an app, listening to music and surfing the web (sometimes happens at less demanding tasks), the phone decides to free up some memory and it goes ahead and kills all background services instead of closing multitasking apps. So my whatsapp service, music player and play store gets killed and restart after a short while. Annoying.

I can provide a logcat, but the bug is easy to reproduce, so I figured I do not have to :p

Oh and thanks a lot for this CM rom, it is miles better than stock. Keep up the good work!
[LG Optimus 4X HD] Demetris:
You know how to prolong battery?

Prevent ultra-fast charging by using lower voltage limit and keep battery cool.
[LG Optimus 4X HD] Demetris:
settings->developer options->background process limit.
[LG Optimus 4X HD] EB20XY:
you are right
[LG Optimus 4X HD] bilbo75:
Demetris a question:

Do you think that there is room for improvement on wifi power management?

Wifi still drain a lot of power on our phone...:(
[LG Optimus 4X HD] Demetris:
Sure sec ;)

Edit1:

Done :)

https://github.com/CyanogenMod/lge-kernel-p880/commit/a040ab0ad389663acbc352d2ab7c963e30ea11b7

Edit2:

And done

https://github.com/CyanogenMod/lge-kernel-p880/commit/922135fd9429efc19296126b1bf71a5ec2da7dc1
[LG Optimus 4X HD] EB20XY:
Yeah, a new nightly build is now available on the official CM site:

http://download.cyanogenmod.org/?device=p880
[LG Optimus 4X HD] ottomanhero:
[MENTION=4038245]playitlouder[/MENTION] is right.Memory management in this ROM is problematic.I've tried to change a few sysctl values, it got better but still not as good as how it should be.Whenever there's a OOM situation, I get a FC about apps which use services.This causes my phone to freeze until an app is cleaned out of memory before service restarts itself.

So basically, in an out-of-memory situation the phone kills a service, before/while service is restarting an app is cleaned out of memory, while that app should directly be cleaned without any services being killed in the first place.Which causes battery drain and freezes in certain conditions.

That has no effect on how android manages apps.It only makes it close oldest background apps once the limit is reached, so in out-of-memory situations this has no effect other than delaying killing of services by a bit, which will only delay when the limit is reached.But if I leave multiple memory eating processes, such as games in the background this limit will have no effect at all.

I may want to run more than 5 apps at the same time, with each of them having low memory usage, not triggering OOM.But if I set the limit to say 3, I will not be able to multitask like I should and if I increase the limit, it will be useless when big-memory consuming apps are in the background.So this really is not the solution we need.

Services shouldn't be the processes to be killed first, as they always restart hence causing battery drain.I never leave anything in the background unless I'm multitasking, yet I've faced these freezes caused in OOM situations and service restarts myself despite this.
[LG Optimus 4X HD] bilbo75:
Awesome! :)
[LG Optimus 4X HD] dimi89:
In CPU settings i found min cpu freq-102 max cpu freq-0 .. is it bugg or it suppous to be like that ? I read somewhere it is bug but got fixed ?
[LG Optimus 4X HD] bilbo75:
[MENTION=1149134]Demetris[/MENTION] said that's related to ramdisk. Anyway that bug should be already fixed, maybe the fix still needs to be pushed... Anyway set the maximum frequency at the right value or you will get big slowdowns.
[LG Optimus 4X HD] Demetris:
Fixed :highfive:

https://github.com/CyanogenMod/lge-kernel-p880/commit/be696766a500ca61f154dbc8ac32d4df374e7117

Enjoy.
[LG Optimus 4X HD] playitlouder:
Awesome fast Bugfixes!

I will give official cm kernel another try tomorrow. The custom kernel I mentioned drained my battery to zero in sleep (maybe WiFi problem I don't know). Draining 40% in standby is not quite acceptable :P

Have you compiled a new build with all the fixes? Are all slowdowns gone now? Btw: I noticed the highest Frequency 0mhz bug also in 8.8 nightly.

Thanks for your awesome support!

Is the rom actually running on kitkat compatible (graphics) blobs now? Haven't been around here for a while.
[LG Optimus 4X HD] Demetris:
Butter smooth here. Just set your preferred high freq manually(not high in my fix list)

We dont have kitkat blobs, last usable are from 4.1.2
[LG Optimus 4X HD] Kanad:
Dear Demetris,

Can you please look into following commit for linearly scaling the cpu frequencies?

https://github.com/stratosk/kernel_msm/commit/9df03b662b9c213c75ac082138f5ab8afadb9d94

Patch by Franco based on this

https://github.com/franciscofranco/Grouper-3.1.10/commit/5d0c161d139760e44b9d4ca3755ab92aaa1f3db9

Also, a small query, official cm has support for mounting the usb otg but no support for usb otg in kernel? Can you merge the commit from iodak on usb otg?

Thanks for awesome work no lag at all on 8.08 nightly.

Regards,

Kanad
[LG Optimus 4X HD] creativeusernamea:
Nightly from August 9 runs really smooth again, great work :)

Only problem I have is that GPS no longer seems to be able to get a fix :/ I did a full wipe before installing August 6 when it came out, then used the updater app to update to 08 then 09.
[LG Optimus 4X HD] Yasioo79:
Gps work great on my device. Gps apps catch signal from 30 s to 2 minutes. I have latest build (09.08)
[LG Optimus 4X HD] amkirk94:
I ran some tests on the latest nightly (09.08) related to miracast.

It seems that the phone detects the TV and the TV detects the phone.

They can establish connection, but when the phone is ready to start casting suddenly it disconnects.

I tried that many times, did reboots and stuff, and the problem is always the same.

The good news is that we seem to be getting somewhere with WiFi Direct! At least the 2 devices establish a connection now!

Also, I would like to report that for me the network issues are totally gone(at least that's what it seems so far). Can anyone else confirm that?
[LG Optimus 4X HD] EB20XY:
have also no network issues at all.

no lost signal etc.

all fine
[LG Optimus 4X HD] bilbo75:
Inresting patches, especially the original one for ondemand.

Let's see if Demetris will try them.
[LG Optimus 4X HD] wilson3q:
[MENTION=1149134]Demetris[/MENTION], any space for improvement over gpu drivers and over clocking? Thanks for the great patches you have done recently.
[LG Optimus 4X HD] bilbo75:
Well, gpu drivers at the moment are from 4.1.2.

The new ones come from Grouper and for what I know they will not used on official Cyanogen.

Same story for overclocking. Cyanogenmod aim to be rock solid. Overclocking or undervolting aren't....
[LG Optimus 4X HD] EB20XY:
but if the gouper blobs from nexus 7 are made exactly for the same hardware as we have, why not ?

It is no rule only to use drivers only for one phone, if the hardware is exactly the same, or what ?

Where is a rule written against that usage, if we test it and it works fine ? Even nightlys do not make a expectation about being "rock stable" at all.
[LG Optimus 4X HD] Flying_Bear:
grouper blobs have issues in apps that old blobs do not have
[LG Optimus 4X HD] EB20XY:
so these "issues" are in unoffical cm11 for p880 existing and they can never be "wrapped away on kernel side" ?
[LG Optimus 4X HD] Flying_Bear:
they aren't kernel related, and yeah they're noticable in both omnirom and unofficial cm11. some camera apps don't work, some show green preview on panorama/photosphere, skype showing green screen, translator apps showing green screen, qr scanning not working directly but only from file etc.

i think these issues are too big for official cm11 team to tolerate in their rom
[LG Optimus 4X HD] bilbo75:
Grouper blobs "work" quite well with a HUGE work of reverse engineering of Adam77Root. Anyway this work can't be perfect and rock solid. There will be always some glitch, some function not implemented well, because you have to figure first how it works and you are alone without documentation watching just a binary file....I think it's already a miracle what we already have.
[LG Optimus 4X HD] EB20XY:
Thats all true, but are the actual used binarys better documentated ?

Well as I understand all feedback: It would be allowed to use the grouper blobs but as "state of the development" there are more bugs/issues as with the ones we have at the moment in official cm11. So we test it in omni and unofficial and ...?
[LG Optimus 4X HD] Puwu:
GPS broken with nightly 0809?

Today i updated from 0724 to 0809 and now i dont get a GPS fix. My phone only finds one or two satellites within a minute. And after 5 minutes it found 6 satellites and still no fix! :(
[LG Optimus 4X HD] gingerboy92:
GPS Test shows gps off for me. lol.
[LG Optimus 4X HD] vladi-it:
And nord point to sud
[LG Optimus 4X HD] EB20XY:
I also have now the gps non fix problem
[LG Optimus 4X HD] Puwu:
After 25 minutes my phone got the first fix. And after that, it takes only 20 seconds for a fix.

But after reboot 6 minutes for the first fix. Then 15 to 20 seconds for a fix.
[LG Optimus 4X HD] EB20XY:
well, days ago the fix works great from beginning.
[LG Optimus 4X HD] Yasioo79:
As i said few post ago. For me gps and compass works great. North in compass is real north

I have done clean install of the last nightly
[LG Optimus 4X HD] Puwu:
now i updates from 0809 to 0810 and the first fix after reboot is within 2 minutes. Then again 15 to 20 seconds for a fix.
[LG Optimus 4X HD] maderos:
No cyandelta again?
[LG Optimus 4X HD] Demetris:
Its Raining RCU updates :D

Enjoy.
[LG Optimus 4X HD] playitlouder:
Could we try the HTC one x(+) gpu blobs? They are made for 4.2.2, so in theory better than we have at the moment. :confused:
[LG Optimus 4X HD] bilbo75:
Huge commit ! :good:

---------- Post added at 10:39 PM ---------- Previous post was at 10:37 PM ----------

The choice to use Grouper blobs it's for support Android L on our phone. Grouper is still developed and should get Android L update , HTC one + who knows.
[LG Optimus 4X HD] Climuff:
Demetris, have you already tried to find what causes the mobile network setting bug? Has everyone the bug or only me?
[LG Optimus 4X HD] xperia u20i:
http://www.xda-developers.com/android/google-io-2014-app-source-material-design/

Maybe we soon have materijal design goodies on our phone. If i understand well, source code is pushed to github.
[LG Optimus 4X HD] xperia u20i:
With latest nightly i have Huge battery drain. 25% over night. I think is problem with baseband wakelock, 1h 50min...
[LG Optimus 4X HD] dimi89:
Nope not for me ... Even with 3g enabled (in my room it have the worst signal ) and still not that much.Check better battery stats.
[LG Optimus 4X HD] bilbo75:
No problems so far. Only 2% in airplane mode. Only wifi still a bit high drain IMHO.
[LG Optimus 4X HD] vieri_202:
2 hrs 52 mins screen on ...1hr data on rest wifi on..still 25% remaining
[LG Optimus 4X HD] xperia u20i:
I checked bbs and nothing special only baseband power wakelock is little high i think...
[LG Optimus 4X HD] Demetris:
Don't report bugs when you are using custom kernel's you ofc be ignored but thing is you are confusing the community.

Thank you
[LG Optimus 4X HD] Climuff:
I dont use costom kernel.

So have you tried to find the mobile network settings bug?
[LG Optimus 4X HD] EB20XY:
will that be included in next nightly ?
[LG Optimus 4X HD] Demetris:
Yes it will. :) and btw 11/08 is out!

This is for 12/08 :D

https://github.com/CyanogenMod/lge-kernel-p880/commit/0f06f4a1f2218dd1d5489223643cb210ca45afe6

:cool:
[LG Optimus 4X HD] vladi-it:
11/8 is running and is smoother then ever. Thanks again :))
[LG Optimus 4X HD] EB20XY:
looks good.

But why is no commit of the 2 to see here in the changelog for P880: http://www.cmxlog.com/11/p880/ ?
[LG Optimus 4X HD] Demetris:
Because I can bypass gerrit. I post the worthy changes anyway, why you need them on that log?
[LG Optimus 4X HD] wilson3q:
Great commits! Can you look at the network part of kernel? The internet download speed is quite slow. When I am using idoak v10, my download speed can be 1.5m...only 250k while using stock cm kernel. Maybe relook at your recent tcp/ip commits...

BTW buttery smooth for 1108 noghtly. Thanks!
[LG Optimus 4X HD] Demetris:
I"ll have a look
[LG Optimus 4X HD] EB20XY:
the nightly from 11.8. works really fine for me sofar.

Thanks!

Also less types of errors in the catlog. Perhaps the rest can also followed up ?

btw: The GPS works for me with 11.8. nightly again perfect and fast !
[LG Optimus 4X HD] EB20XY:
do you config path https://github.com/CyanogenMod/lge-kernel-p880/tree/cm-11.0

or https://github.com/CyanogenMod/lge-kernel-p880/tree/stable/cm-11.0

for the nightly builds ?
[LG Optimus 4X HD] Climuff:
Why are you not talking about the mobile network stuff bug? I asked several times about it and you dont answer... Please just take a look why the settings are not correctly adopted :( I now have no mobile data on my phone for about a month... Its horrible, but I dont want to change to a different ROM, I always say "next nightly will fix this..." ^^
[LG Optimus 4X HD] SnowRaptor:
I suggest you add a logcat when reporting the issue. Otherwise Demetris can only guess what's wrong.

The idea of these nightlies is exact to iron out these problems and it's our job, as users, to help development by accurately reporting bugs, not just demand fixes.
[LG Optimus 4X HD] bilbo75:
Probably the problem is coming from your APN.

1)Backup in recovery.

2)Full wipe with factory defaults (format /system and /data manually too!)

3)Install latest nightly (don't install anything else, no GAPPS, no custom kernels or any other bull****, JUST the rom).

4)Reboot

5)Check that you are APN are correct and if you have data connection.

6)If you still have problems post logcat and tell us what carrier do you have.Also a snapshot of your APN settings would be useful.
[LG Optimus 4X HD] Legion69:
I tried with stock/iodak/optimus kernels and download speeds are similar. Nightly 11.08.

Also ROM is very battrery friendly, I have 1-2% drain at night (about 7h), WiFi off, GSM 2g. :D
[LG Optimus 4X HD] Climuff:
I already did a full wipe 2 times and I also always formatted system and data manuelly just for fixing this issue and it never helped... I always installed the gapps, but why should the problem be caused by the gapps? Its just so annoying to do full wipes so often, all this configuring of the google accounts and the installing of all nearly 300 apps, it just takes so much time...

The problem isnt that there is some mystical problem. Its just that everything I do in the "mobile networks" settings has absolutely no "real" effect. For example, when I turn on mobile data in normal settings the icon in the upper bar isnt changing. And when I click the icon in the upper bar for enabling/disabling mobile data the slider in normal settings isnt changing. So just all stuff I do in the settings have no "real" effect, beside that the slider and the checkboxes are looking different... So I'm very sure the APN settings also have no effect and without APN settings I cannot get mobile data.

I'm sure this is a problem which is easy to fix, just some missing function call or whatever... I haven't myself programmed android stuff, but it just look like some bug which is caused by some little slip ^^

Is the terminal the only way for creating a logcat?
[LG Optimus 4X HD] wilson3q:
Screenshots attached.
[LG Optimus 4X HD] bilbo75:
That switch disable data connection not phone calls or sms. If you want disable that stuff go in airplane mode.

Anyway, is it a BIG problem???

You can get a logcat also with adb from shell windows.On XDA there are a lot of tutorials or just use google.
[LG Optimus 4X HD] Legion69:
I think You messed with rom config, did You clean cacje and dalvik before You flashed kernel? Did You changed tcp algorithm?

Regards.
