Hi [MENTION=1149134]Demetris[/MENTION], thanks for your dedication to the LG 4X.

I just want to tell you guys that I first tried the CM roms in last December (bought the phone in September), and in all the available cm roms till January (cm10.1, cm10.2 and the first cm11) I had serious radio losses. I lost some important calls, some of them work related, and was forced to use stock rom.

But the fact is that I gave CM another try in early June, I've been using CM11 for almost a couple of months now, and I'm having zero signal losses.

I really don't have an idea of what the developers did. I'm living in the same place, and using the same carrier. The phone is the same, so it must have been some software change that did the trick.

I'm loving the CM11 rom since you took over, and the only thing that sometimes bothers me is the random gps catching time. Sometimes I wait for more than 10 minutes without getting signal and finally giving up. Also, sometimes the double tap to sleep feature doesn't work. But, other than that, the rom is perfect.

Thanks again. :good:
[LG Optimus 4X HD] xtra0581:
I would consider this as a bug...
[LG Optimus 4X HD] xperia u20i:
"Only" reason why almost for sure we won't get STABLE CM11 is radio, right? I wasn't have that issue so latest CM11 for me (hopefully) will be stable, who cares for STABLE mark ;) (only if that doesn't mean END of official CM support :rolleyes: ) Thank you [MENTION=1149134]Demetris[/MENTION] Hope you will continue with developing when CM12, or what ever will be called, comes out. Thanks once again.:good:
[LG Optimus 4X HD] amkirk94:
Thanks for stating that, we really appreciate it. I personally do experience network issues. I hope we find the cause of this failure, so that we can have reliable and stable releases again! :)
[LG Optimus 4X HD] EB20XY:
can you please post 2-3 logcat protocols when it is happening
[LG Optimus 4X HD] amkirk94:
Sure! It's generally happening when the battery is low I think (not sure yet). I'll post some logs as soon as possible!
[LG Optimus 4X HD] Bubino75:
Hi,

I have install the last nighly (24/07)

I have format /system as suggest [MENTION=1149134]Demetris[/MENTION]

Format cache and dalvik cache and then install the zip of ROM

When I restart I found problem with

-signing of pushbullet (I clean data app but the problem was always here. Now I disinstall the app)

- problem with Google keep (see attach picture

- problem with Google play (see attach picture

My internet connection it's OK, other apps works fine

I don't see great improve of performance.

Same freeze, and camere take second to start up

I use official cm gapps (0606)
[LG Optimus 4X HD] tool_king:
Maybe you should give the actual GApps a try:

http://xdaforums.com/showthread.php?t=2397942
[LG Optimus 4X HD] Bubino75:
But why I can't find it on cm wiki?

http://wiki.cyanogenmod.org/w/Google_Apps
[LG Optimus 4X HD] tool_king:
There is no connection between GApps and CM. So I don't quite get your point.
[LG Optimus 4X HD] alberteske:
cm wiki still being a valid package of Gapps :good:
[LG Optimus 4X HD] Bubino75:
With the package on wiki I have all problem that I write above

With

pa_gapps-modular-micro-4.4.4-20140725-signed.zip

it is even worse (see attach)

So, what package I have to use?
[LG Optimus 4X HD] tool_king:
Did you wipe system, cache and dalvik before flashing the ROM and the GApps?
[LG Optimus 4X HD] Bubino75:
Yes!

Now with WiFi, all seems to work fine (pa -gapps)

Strange, because my mobile connection works fine with other apps
[LG Optimus 4X HD] Optimissimus99:
Does grouper support wifi direct? Maybe we can apply grouper blobs...?
[LG Optimus 4X HD] Graveen:
Hello,

On my side everytime i flash an update (with TWRP or CWM), i'm forced to reflash GApps (PA_Minimal_444). Now trying with Full package from today, but i wonder if you noticed this problem ?

Thank you !

Font support for Cm11 launcher

Dear Demetris,

Can you please look into following commits

https://github.com/CyanogenMod/andr...mmit/cf43a17640a7eede4106670f97e0834b5ea0f976

This commit removed the support for font change. Actually when font is changed in cm theme manager it will change all the fonts except the fonts used in Trebuchet icon lables. IMO it breaks the harmony in the system e.g. one font is used for system ui, quick tiles etc. and one is used only for trebuchet icon lables. Wanted to just point out the issue with trebuchet nothing else.

Regards,

I've got some logs about the radio signal loss.

This COULD be due to bad service from me network provider!

The weird thing about it though, is while on Quick Settings panel it was saying "Emergency Calls Only", my status bar was showing that my signal was fine.

It's noteworthy to say that I couldn't make calls during the time of that state.

After a few seconds my network came back to normal.

If you find it hard to locate the network error, it is just before I give su access to CatLog, so that I can capture the logcat.

I'll provide more logs, if needed.

(actually look at the log that I give at page 57. It is more representative of the issue)

How is the battery life for you guys on CM11?

Because for me it's pretty poor and I wonder if it's CM11 or something else :confused:
[LG Optimus 4X HD] xperia u20i:
You should first try to find source of drainage with better battery stats, open it, recharge full and look in to BBS trough day to see if is any wakelock issue or something. For me battery some time is surprisingly good, but sometimes surprisingly bad. Depends on a lot of factors. Try BBS if you didn't yet. Maybe you find something, maybe anything. If problem persist try full wipe. And yes, how poor do you mean? Our phone ain't good to battery so that could be normal. I have max 2:30 screen on time but mostly around 1:45-2:00. But games REALLY DRAIN battery like hell...

Current status:

41%

screen on 1h 38min

on battery 9h 38min

...and that is ok for me...no UC or UV...
[LG Optimus 4X HD] Artisto:
@UP

By poor I mean that I can get about 2-2,5h of on-screen time while on stock ROM I was easily reaching 3,5h.

I did an undervolting, underclocking and turned some power-saving features found on iodak's kernel - yet there's still quick battery drain while browsing internet on wifi - less than 2%/min even on the lowest brightness.
[LG Optimus 4X HD] xperia u20i:
For me that's ok for custom rom. You can't expect more of that(maybe in future with another android system and depends how much can be squeeze from iodak's kernel, since Mourta continue iodak's work on modaco forum, so we will see how much he can do). O4X is battery hungry phone and that's that. We all must live with that, or buy another phone :(
[LG Optimus 4X HD] Artisto:
@UP

Then why stockROM was capable of getting such a good battery life? It's not phone's fault if it was capable of being energy frugal :)
[LG Optimus 4X HD] xperia u20i:
yes it has better battery performance, i must agree, but ain't so good at overall performance, customization..., that's why we are all here and use custom rom. :p ;)
[LG Optimus 4X HD] TuxBrothers:
LG 880 has poor battery life, its hardware consumes a lot of battery power.

I have 2 880's and the only thing seems to work is a kitkat based rom to extend battery life.

The one with a clean CM 10.2 is rocksolid but consumes a lot more then the CM11 based phone.

My other phone a S3 with CM11 consumes only 10% per hour on screen.
[LG Optimus 4X HD] varadinum:
It now lasts!

Battery Life...Battery Life...Battery Life...

Please, all aplications, gapps, kernel, and rom uninstall.Take out battery!

And so you have a SUPERPHONE, SUPERCELL!!! :laugh::laugh::laugh:
[LG Optimus 4X HD] Flying_Bear:
that means your s3 should last 10 hours onscreen from full charge to empty. which is impossible, since lg g2 has 7-8 hours, and has one of the longest lasting batteries
[LG Optimus 4X HD] TuxBrothers:
Jep with Boeffla kernel it can do 10hrs on screen, believe it or not.... ( idc ;) )

Meanwhile i flashed Beanstalk with the AD improvements on one of the 880's if it has improved battery life.
[LG Optimus 4X HD] mac.daferriera:
Sorry for the little off topic, but regarding our cellular (3g) problems, does anyone know if stock ROM is unaffected?
[LG Optimus 4X HD] Flying_Bear:
Well, 10h is insane tbh. Best ive seen on our device is 5.5hours of heavy video watching. If s3 can double that, thats quite impressive.

@ mac

Afaik it is unaffected
[LG Optimus 4X HD] Bubino75:
How can I read all the message about extension in CM HOME?

Double click and others gesture doesn't work!

Thanks
[LG Optimus 4X HD] KrisJoe:
That's because nvidia decided to make Tegra 3 with 40nm process, while Samsung made their exynos 4412 with 32 nm HKMG process, which is much better in terms of battery duration.

Cpu differencies asides, our smartphone has a very nice display, but it consumes a lot of energy, despite what nvidia said about their new technology with displays.

In short words, we would need to replace some hardware parts to get more battery duration, which is not possible. What devs are doing with our smartphone is already a very nice and appreciated job, without them we wouldn't have Kitkat or whatsoever.

Sadly, our smartphone wasn't thought to be lasting too much, as nvidia didn't expect battery life to be that bad in smartphones. Bad thing about performances is that they made it with 40 nm process, and cortex-A9 instead of cortex-A15, so it means more laggy and more battery drain.

So we really can't expect too much from our device, but yeah, devs make miracles. Let's believe in them.

A little offtop, yet I did some kind of experiment on my current software package (CM11, iodak 10)

https://drive.google.com/file/d/0BzxkqDLnt_YZMTJySFNGVFdabzA/edit?usp=sharing

https://drive.google.com/file/d/0BzxkqDLnt_YZRjJYRE9MLW5GMU0/edit?usp=sharing

https://drive.google.com/file/d/0BzxkqDLnt_YZaDBnSGphQ1o1d3M/edit?usp=sharing

Now to explain - I wanted to see how much energy the screen consumes so I left the phone with screen turned on for.. really long. It was showing only my home screen with widgets and status bar - so the image wasn't completely static and - for example - the time was changing every minute or the weather was being updated every 2 hours.

The wifi was turned on all the time and phone was switched to 2G. Brightness was about 13%.

Conclusion - screen is pretty energy frugal on low brightness, but Tegra3 just kills the battery... :(
[LG Optimus 4X HD] amkirk94:
I'm sending you guys another example of the radio error that we have been facing. This one in particular appears to interfere with the radio specifically when the battery is lower than 20%! I rarely get this "NO SERVICE" error when I'm at 20% or more.

The radio issue (for me at least) has definitely something to do with the battery being bellow 20%!

Can someone else confirm that the radio issues appear ONLY when the battery is low?

Here is the log: https://www.dropbox.com/s/f6upypc94m85pym/2014-07-26-18-18-02.txt
[LG Optimus 4X HD] Navios92:
I have the exact same problem. When the battery is charged I have no issues but when it drops below about 20% I start to lose signal.

It happens exactly when someone calls me. I slide to answer but nothing happens as if I didn't do anything. I slide again more than once then I get disconnected and lose signal. Sometimes it comes back after a minute or two but when I make a call I get the "no service" error and lose signal again.
[LG Optimus 4X HD] Optimissimus99:
On my phone 3G is Very buggy / unstable on CM11 (official source) and Omni (p880-dev/android-4.4) while its very stable on Unoficial CM11 Carbon and many more (p880-dev/cm11). My main problem is That i am forced to re-enter sim pin - in most cases with low battery) Maybe you can try to import radio changes from the cm branche oft p880-dev
[LG Optimus 4X HD] amkirk94:
I rolled back to 17/06/14 official CM nightly, and I was surprised to find that the signal loss issues were not present there, even with low battery. I'll try unofficial CM, and I will report back!

EDIT: For some reason I can't flash the unofficial CM, I don't know what happened to it. I hope that someone else provides some feefback or log.
[LG Optimus 4X HD] Navios92:
I've haf this signal issue on low battery with CM since as far as I can remember.

About unofficial CM, I think you need to have f2fs compatible recovery.
[LG Optimus 4X HD] xperia u20i:
Yesterday i have signal loss and some nasty system ui fc, but this is probably because theme. Problem started after 23:45 h.
[LG Optimus 4X HD] tuneq:
Since the last 15 nightlies I can't anymore connect to any wifi, even changing kernel it never works.
[LG Optimus 4X HD] xperia u20i:
Did you make full wipe? Did you try connect to other network. Does it work on other rom's, now, not before, try install other rom? Give some info not just complaining like a baby. Sorry, but if you need help, than give some more info about your problem so we can help you.
[LG Optimus 4X HD] vladi-it:
Yesterday I tried to install unofficial, so I've downloaded it and pa.Gapps mini. I had trouble with unofficial, so I back to official, format system, install pa.gapp. delete velvet.apk and install g search from market. I stay the full day in 2/3g and no one loss! All is working smooth. Are you using Cm.Gapps or pa.Gapps? Can u report?
[LG Optimus 4X HD] giurly:
OK, but with stock 4.0.4 I had easily 36 hrs between charges, 48 sometimes and none of my friends with S2 or S3 gets this. Since stock 4.2 battery life gone very bad. Same in CM10.2. Better in CM11, but rarely over 24. I'm not complaining with devs, only to say P880 can save energy somehow. I disabled Google Now and some stuff related with position to improve battery life with some gain...
[LG Optimus 4X HD] Optimissimus99:
I saw that in Omni there was a patch a few days ago wich enables hotword detection on pre-kitkat blobs, maybe demetris can fix hotword with this

Edit: or is it already fixed?
[LG Optimus 4X HD] alberteske:

[LG Optimus 4X HD] Navios92:

[LG Optimus 4X HD] alberteske:

Then you will know.

It is what it is, and afaik no one can do anything about it.

An interesting quote

"Uninstall to save lives!! Had to be uninstall and revert to manufacture mode. Drains my battery in a few hours and cant really stay out too long before charging. Also, uses too much cpu power."

Rotation issue

Hi! Sorry for my Bad english.

Only i have this rotation graphic error after wake up the phone? At the same time with KitKat development started.
[LG Optimus 4X HD] xtra0581:
I have this problem also sometimes, but not often and I don't know how to reproduce it...
[LG Optimus 4X HD] xperia u20i:
It could be keyboard related and rotation i think and if phone is locked and sleep :confused: ...i have that problem on o2x also...
[LG Optimus 4X HD] KrisJoe:
In the latest nightly (the 17th) does the kernel has improved that much? Usually the stock kernel of cm11 offy was a bit slower and laggier, but from what I read it seems Demetris added a lot of new things in it, so I think I'll try the stock kernel and see if it has huge improvements as I hope. :)

Unluckily what brings me down is the loss of network, which sometimes needs the restart of the smartphone to work again, draining the battery each reboot. :( please Demetris help..!
[LG Optimus 4X HD] dimi89:
For greenifyed to show system apps you must donate or google patch for it.Still using 14 th nightly and everything works fine no lagg or any other problems.

I've never had signal loss with no coming back with stock CM kernel. Used to have it with old versions of iodak but not with v10.

And 17th nightly is kinda smooth but not as smooth as with iodak kernel of course.
[LG Optimus 4X HD] KrisJoe:
I don't know why but that's what happens with me, with every kernel... Btw I can't test the cm stock kernel further as I need the fast charge option which is not available in the stock kernel. When I'll have time I'll try to make a full wipe, then a clean install and see if network losses will happen again.
[LG Optimus 4X HD] PafcioPjay:
For me the same thing - I'm losing my range and I need to reboot or switch between networks to get back.
[LG Optimus 4X HD] alberteske:
latest nightly (the 17th)

Big battery drain and problems of GSM disconnected without notice :mad:

I think Demetris didn't apply yet his improvements but they will come son :D
[LG Optimus 4X HD] ottomanhero:
I'm on 17th nightly and experiencing no lag issues atm.I'll report if anything goes wrong.

Using iodak v10, on dalvik and planning to switch to art soon.
[LG Optimus 4X HD] Flying_Bear:
it is already fixed. you just need to have google now as non-system app, so you need to have it installed from google play store instead flashed from gapps package
[LG Optimus 4X HD] Optimissimus99:
But thats just a workaround... I think the patch fixes the issue general:

Edit: here is a Link: https://gerrit.omnirom.org/#/c/8671
[LG Optimus 4X HD] tuneq:
It worked on previuos cm11 nightlies. I made ota update day day to newest version, and I made only wipe data cache/ wipe dalvik.

Sometimes it fails to scan networks, some others it makes the scan, but if I try to connect to any available wifi the setup menu crashes!
[LG Optimus 4X HD] xperia u20i:
try to make full wipe then. It's a little annoying process, i know, but maybe you solve your problem...
[LG Optimus 4X HD] tuneq:
I'll try then.. Thanks!
[LG Optimus 4X HD] Climuff:
I'm now using 0727 nightly and developer options still not work... When will this be fixed?

I also noticed that mobile data isnt working... I usually dont use it often, maybe once a week, so I cant tell you since when it didnt worked. But some weeks ago im pretty sure it worked :p
[LG Optimus 4X HD] maderos:
All is fine. Data and dev options works well from day 1.
[LG Optimus 4X HD] Kanad:
Dear Demetris,

This is just a small request, can you please look into the issue of stock kernel not going to 51 MHz step when screen is on? Tegra3 does support this frequency when screen is on.

Thanks and regards,

I've been experiencing sluggishness with every nightly I installed since April. (before that I was on CM10.2, still slooooow)

Following instructions on this thread, I decided to format system and wipe cache and dalvik cache when updating.

Now I get sluggishness AND gapps "stopping", like Google play services, drive, keep and even lockscreen (I enabled background apps freeze notifications to diagnose).

Trebuchet seems to reload every widget everytime I go back to my home screen from an app.

I'm on 20140723 and will update to 200140727 after I get some ideas from you, guys. This behavior is persistent across different versions, though.

Any ideas where I should start trying to solve this? Thanks!

P. S.: is there a better backup app than Helium? I had problems restoring stuff with it and I don't trust it to do a full wipe anymore.
[LG Optimus 4X HD] EB20XY:
for me the last nightly 29.7. works fine.

But first I get error mesages for the calendar app.

But after shutdown and restart all work good.
[LG Optimus 4X HD] Graveen:
Same as you i think you should try unofficial cm11.

[LG Optimus 4X HD] KrisJoe:
Rom's getting very much better with connectivity, now lost connections are nearly rare events and I'm quite satisfied about it.

I was thinking that we may have memory leak issues as we don't have much free ram and we can't multitask that much. It's like I usually have between 170-80 MB of free ram, isn't that too low?

Thanks for the great work!
[LG Optimus 4X HD] ALuedtke:
My P880 has exactly the same behaviour! After a reboot everything is fine and (relatively fast). But after several hours, the phone feels like there is only a cpu with 500MHz built in or like Android is swapping applications in and out. Sometimes it really takes 4 or 5 seconds between tapping an icon/menu item and a reaction from Android. A complete black screen for several seconds after tapping something is really often the case.

My first idea was: it's probably Trebuchet. I installed Nova Launcher (free version), rebootet and the phone was fast again. But after several hours it's the same slow behaviour as before. I can't tell, when this happened the first time, but I think it's like this for some weeks now. I tried to help myself by regulary closing all unneccassary applications to free up memory but that didn' help noticeably.

Are there any other recommendations beside full wipe and new installation? I use the nightly from july 23rd with standard kernel and NO optimisations.

Are there more people like SnowRaptor and me experiencing this?
[LG Optimus 4X HD] EB20XY:
can you please try latest nightly and report again. ;)
[LG Optimus 4X HD] Optimissimus99:
Try to mod the minFree values, this made my phone very fast

Sorry to ask this (I never did any optimisation), but where do I find minFree and what value are you using?

Just Download minfree manager from play store, or use trickster mod donation.

Or use the task manager of ROM Toolbox. (Slide Menu)
