I had a caseilogy bumper case installed for about 2 weeks. Took it off to pull battery and noticed the same small scratches. I have yet to put the ccase back on the phone.. i will take my chances without a case.
[AT&T Samsung Galaxy Note 4] svengalis:
I really wish that they didn't even include the paint around the outside of the phone. It really takes away from the look of the phone, on the black one anyway.
[AT&T Samsung Galaxy Note 4] arjun90:
The Otterbox Cases (Defender and Commuter Series) doesn't leave scratches and kinks on the Metal Edges of the Note 4, also depends how you handle it while placing into a case.

Euphoria-Light kernel

Here is the "light" version of the kernel.

Different from Euphoria stock kernel:

-O3 optimized

-Removed most debugging, tracing and logging

-Removed modules support

-Less code means a lighter and hopefully a little bit faster kernel.

This is an experiment and it might not be 100% stable. Use on your own risk.

[LG Optimus 4X HD] ex0rt:
I have noticed few issues.

- When you swipe up quick settings it has a small "glitch" in rendering (cosmetics)

- When I try to call someone it just ends a call with message "Call not sent." (major)

- When you turn on and off flashlight from quick settings, button disappears (cosmetics, since it resets when you swipe it again)

My phone is getting super hot during calls. Anyone else facing this?

Should I share logs for this problem?
[LG Optimus 4X HD] ViniLima:
Tried to flash again. Everything works now (original kernel and Mourta's kernel). I can make calls, RIL is good, I can pair and play with my Ípega BT controller. Very good! But, in general, the UI still slow while opening apps or changing between open apps. Some of them FC due to slowly opening. But, that's beta, what can I say? I loved to use Android L =D Keep with work!
[LG Optimus 4X HD] tuncay_93:
I switched to "WerewolfJB" kernel and things are a little (noticeable) better.

In my case mourta kernel was even worse than stock kernel in the rom.
[LG Optimus 4X HD] varadinum:
Works or does not work

Is there such a big difference between p88 and p880? For me the rom works not correct. System keeps crashing.

Some write that this rom is working properly. I can not believe it. Sorry! :confused:
[LG Optimus 4X HD] rellagher:
What do you mean p88 and p880? There's only the LG p880 (Optimus 4x HD), thats the model of the phone... Do you mean cm11(android 4.0) vs euphoria (android 5.0)?

Some write this rom is working properly some don't, we're at early builds of lollipop.
[LG Optimus 4X HD] SuperLamic:
did you try his 3.4 kernel? I'm using it now with Euphoria and it works 200% better than with built-in.

No frequency drops at all and even that micro-lags when scrolling are smaller + apps launching is definitely faster.

I only sometimes face issue with music playback.. but I know that is probably caused by custom kernel, so that's the reason why I'm not spamming this thread with it :D
[LG Optimus 4X HD] xperia u20i:
[MENTION=3081601]alfsamsung[/MENTION], any clues regarding ril?
[LG Optimus 4X HD] asgz:
You mean mourta 3.4 kernel ? I tried before with kit kat and my device had almost fried. So my question is with Euphoria do you have overheat issues ?
[LG Optimus 4X HD] Ti4go:
3g work with 3.4? only stock kernel work 3g for me :/
[LG Optimus 4X HD] SuperLamic:
hmm, my device is hotter and battery is worser. But I'm using it because I would destroy the phone on my own. I'm really aggressive when I use built in kernel - that lags are sometimes really horrible. I wanted to drop the phone and jump on it.

Maybe you tried some old version.. it got a bit better since last update

3G works as well as on other roms/kernels.
[LG Optimus 4X HD] alfsamsung:
Guys all the lags and heat is because someone turned on ksm by default and it was set up for a desktop computer. It is using 40% of cpu. Turn it off by writing 0 to /sys/kernel/mm/ksm/run

I'm uploading a new build now with ksm off by default.

EDIT: Upload done.
[LG Optimus 4X HD] SuperLamic:
huh? that's wierd -Mourta has enabled ksm in his kernel too and it's still supersmooth.

btw where can I get those values (processes and their cpu usage) ?
[LG Optimus 4X HD] bilbo75:
KSM is not a great idea for a mobile phone IMHO.

It keeps periodically wakeup the phone to try to free/optimize RAM usage. Sometimes is problematic also on servers. I had to tune KSM on my KVM Centos server because it was keeping my CPU usage quite high.

Hold power button and volume- together until you enter in recovery. Then only flash the the rom to get rid of the kernel and you wil be able to boot again or restore a backup if you made one
[LG Optimus 4X HD] Ti4go:
Guys,

Post your Baseband please.. Maybe there is something to do with bugs?

Mine is V20b-EUR-JUL-17-2013

Kernels Bugs:

Mourta 3.4 - Cant boot

Mourta 3.1 - Boot, But no 3G Data and Random Freezes

WW - No data, Fast!, Freeze on Videos play (like facebook videos, etc)

Stock - Data Work Fine! Almost no signal lost! But TOO MUCH LAG! (No freeze, But when i say LAG i mean 15s LAG)

OPrime - No data, Everything FAST..

* I CAN make/recive phonecalls from every single kernel

So, Im using Stock kernel day 06 release.

Lag is very bad, But... At least i have 3G.. :/

Any ideas?
[LG Optimus 4X HD] sunsettrack4:
I'm using V20c-EUR-OCT-07-2014, and I don't have any lags or freezes, everything works with stock kernel (Antutu: 23,850 points).

Not sure why but I have a weird Baseband version, it's "L6260_MODEM_SIC_02.1233.00" and I have no idea where it came from.

Everything is working fine, though. Stable connections and working incoming and outgoing calls.
[LG Optimus 4X HD] Ti4go:

Still same issue... I think there is something messed up with my Internal Memory, I have low IO points on Antutu... I got 680 last time... :(:(
[LG Optimus 4X HD] tuncay_93:
Also got low "IO" points in Antutu Storage I/O -529 and Database I/O 620

And strangely familiar lags and problems as you explained.

I was installed mourta 3.4.104 and phone boots.But cant take screenshots to show
[LG Optimus 4X HD] varadinum:
Mourta kernel does not work properly. Not a single one.Only stock kernel works smoothly. Thanks

Best regards
[LG Optimus 4X HD] alfsamsung:
If you have problems, it will not help to install another kernel. First make sure you made a clean install(wipe data,system and cache). Don't install gapps, you can do that later. If you still have problems on a clean install, post a log here. I don't have problems besides bugs on post #2, so I can't help without logs.

[MENTION=3435730]xperia u20i[/MENTION]: I still belive there is something strange with your apn settings. There is a "null" there that I don't have and I can't see an attemp on ougoing call in the last radio log. I will do some more log reading tomorrow. And it's strange that it's just a few users, are you on the same operator?
[LG Optimus 4X HD] rellagher:
Yes, but the lockscreen still rotates even if you disable it.
[LG Optimus 4X HD] SmallDesires:
Fair enough. Disabling auto-rotate altogether works for me, though, but that may be a little too drastic a measure.
[LG Optimus 4X HD] masmoe:

it is development thread so please report problem on stock / default ROM only and provide logs. That is the way developer can fix the problem.

Volume Boost during calls

I have observed that we get a volume boot button when the call starts.

It seems it is right now not working. If I press it once, it says "Volume Boost is off".

Pressing again shows the same message.

Does anyone know how to really boost up the volume.

This is one problem I had faced with CM11 of low call volume. The call volume in Euphoria is decent but I wanted to increase it further.
[LG Optimus 4X HD] rellagher:
After using this rom for a few days (well it's my gf's phone, she's the one using as her daily phone), the only thing that bothers her its lag and slowness. When you first flash the rom everything is perfect and smooth but after installing nano gapps and some basic apps (just Facebook, Instagram, what'sapp and outlook) the phone gets very slow sometimes.. Is there any log that I can capture to help?

thanks
[LG Optimus 4X HD] Veacue:
20150106 here - no mobile data. It was working on all of the previous builds, so it has to be something with these 'partially reversed RIL changes'. Stock kernel. Baseband LGP880AT-00-V20b-EUR-XXX-JUL-17-2013.

I'm trying to use this rom as a daily driver, so it's a bit of an issue. In general everything's fine for me and it's really the first bug that I've encountered. Even lags aren't as horrible as some users report.

Thanks for your effort with bringing L to 4X guys!
[LG Optimus 4X HD] xperia u20i:
I just tried one last time, only with flashed rom, and problem is still here. No mobile data connection and can't make outgoing calls.

Edit: And yes, is any other method for change apn settings beside in settings? Because i don't know where to change that from null to something else. Sorry for my ignorance.

The thing i do, is that i compare apn from euphoria and CM and they are same. So don't know where to look anymore.
[LG Optimus 4X HD] yishay:
Very nice rom.

Keep on the good work.
[LG Optimus 4X HD] Komodoketavaran:
My phone is smooth even after installing some apps but not so blazing fast as before...difficult to explain.. Also i've installed gapps right after the rom and everything is ok. The only bug i've found for me is if I have a long time not using the phone and then make a call I lose my signal. Otherwise no signal losses or freezes. Using stock kernel, stock settings/no tweaking app and the good old V20A baseband.
[LG Optimus 4X HD] sunsettrack4:
I'm not able to make outgoing calls because the device always crashes with a black screen then. Incoming calls and 3G data still work fine for me.

I use the build from Jan 06, with stock kernel.

[MENTION=3081601]alfsamsung[/MENTION] If you need logcats, please write a PM to me.

[LG Optimus 4X HD] tuncay_93:

First of all [MENTION=3081601]alfsamsung[/MENTION] the latest build is super fast no lags but when i listen (screen off) to music every 15 sec it interrupts for half an second!

And i didnt realised that the kernel has DT2W
[LG Optimus 4X HD] bilbo75:
Music play is perfectly fine for me. I'm using noop scheduler. I'm on build of 6th.

Double tap is buggy. Also Iodak removed that option in his latest kernel versions. I've tried to enable it and my phone didn't awake anymore. Forced reboot. Disabled immediately
[LG Optimus 4X HD] eric1116:
Nice Rom

My experience for this ROM is very good. Almost everything working for me. I did have awful delay the first day after clean installation but I found after changing default I/O schedule from row to noop, the phone is much more responsive now. Don't have ril problem for me (New Zealand). I had camera FC when swithing to viedo to use stock camera but with supercamer, photo and video are all working fine. Good work alfsamsung. :good:
[LG Optimus 4X HD] Ti4go:
noop worked for me too, much more responsive. 200(+/-) mim 1700 max
[LG Optimus 4X HD] rellagher:
Changed i/o to noop and governor to ondemand, and it is definitly faster! Was going back to cm11, but lets see in the next couple of days if it holds like this. :good:

As great as the rom is, my phone asks for the simcard passcode multiple times, and during those times, my signal is simply nonexistent. On the previous builds a reboot would help and I can make calls normally (haven't had an incoming call when I did have service), but so far on the latest (8-1) build it hasn't. The text under the signal indicator says No service|[my service provider], while I'm having this problem. My baseband is L6260_MODEM_SIC_02.1233.00.

Yes, vibrate is a bit low.

I have a problem. My phone freeces from time to time after i start a app. Most time, when i start "Monster Warlord"
