Hmm, I would like to know why somebody would like to get up their GPU's to 400 MHZ if they're using the power saving mode? That's not even logical. Even the profile for power saving is set up at 128 MHZ. Though I do recognize that balanced may get a little tricky because it is the default.

When I said that I tweaked the performance profiles, I meant that I would go out of the definitions that Franco set up for sure because using stock clock in my opinion isn't "balanced". As for the boot time, I suppose that it loads whatever value is default on GPU clock table, which is why balance looks like selected at first without applying any of it's values to the frequencies.

Anyways, I may only just tweak performance because it is the only one that needs real tweaking.

LiquidSmooth still exists? o.O wooow. As for PA, they're still on 5.0.2. And as of CM, I think they're currently doing nightlies for 5.1.

If your rom is 5.0.2 and below, use SaberMod franco.Kernel. If it is 5.1, use Quanta. :)
[Nexus 4 Android Development] oxxshadow:
is it possible to apply your profiles via kernel auditor or do I have to pay for FKU updater
[Nexus 4 Android Development] zaclimon:
This is a feature unique to FKU only.
[Nexus 4 Android Development] ObihoernchenDE:
Ah sorry I wasn't that clear with power saving mode I mean auto set power saving profile if battery is below xx%. Should have explained it a little more.

Hi everyone..... I am looking for obscenity amoled gama setting.... but quanta v3 doe's nt have....somebody can help me?

Sorry for my English...
[Nexus 4 Android Development] manpildo:
It's surprising to get this kind of performance out of a kernel that barely scales above the min value (384 MHz). As I see it's been counterbalanced by having 2 cores online all the time, the same approach that stratosk uses, but less aggressive. Its up_threshold is set at 95, which I think means that it will sample up only when the load on a core reaches near its limit on a given frequency? In that case I'm pretty impressed by the performance. It retains the smoothness known to android 5.1, but of course not quite like the kernels that are optimized for performance rather than conservative usage.

If I want to squeeze out a bit more performance, is it sufficient to reduce up_threshold?
[Nexus 4 Android Development] dragos281993:
I confirm that reducing the threshold, will give you a boost in performance, but the battery will drain faster. I had it set to 50 and the draining is noticeable, but it's worth it, in my opinion, if you want more performance over battery life.

[MENTION=4217103]zaclimon[/MENTION] sir, I don't know what you did to your kernel, but it became so good... I mean, the battery draining got to 0.3% /hour in deep-sleep mode at some point yesterday, a few hours after I had flashed it, and the dt2w feature works perfectly now, without any delay or unresponsiveness. So thank you for that. PS: using "interactive", with no other tweaks, on cm 12.1.
[Nexus 4 Android Development] Italico:
Do whatever you feel about frequencies and DT2W! ?

It was only a question, maybe a suggestion, but not a request!

Thank you very much for the explanation ☺
[Nexus 4 Android Development] iskandar1023:
Well, my battery seems pretty fcked up.

Suprisingly i get 6,5 hrs SOT with same usage like on other kernel. Mostly on wifi, sometimes on 3g when i was out.

Was only chatting and a few hours reading manga while playing music thru earphone.

This combo really saves my money for battery.

Chroma+Quanta on F2FS

Devs rockz love you all #nohomo

Did you change any tweaks or kernel settings are untouched?
[Nexus 4 Android Development] iskandar1023:
I always push the kernel configuration until it lags, after that i rise up a bit.

For quanta i underclock to 1026 mhz, gpu 200mhz, and -100mv uv across the board

And i still can play virtua tennis too?

You don't have any issues with play services bug?
[Nexus 4 Android Development] iskandar1023:
Nope

[Nexus 4 Android Development] Dor-b:
This bug is driving me crazy , as you can see in the attached SS play services takes 10% of my battery usage.

I've already disabled the wake up through the chroma app-op and killing service using Servicely every 60 secs.

What is your play service version? i'm on the latest..

Thanks
[Nexus 4 Android Development] iskandar1023:
7.3.28 and no wakelock at all

I don't use greenify or servicely

Maybe clean flash can help?

[Nexus 4 Android Development] Dor-b:
I don't think so , on the latest version of chroma i've clean flashed...

God know what will help..

you may want to try this http://xdaforums.com/oneplus-one/themes-apps/mod-google-play-services-update-wake-t3078082

its 0.0.01 version behind but still worth to try.
[Nexus 4 Android Development] Dor-b:
This is what you are using?

If not, what version of play services you are using?

Our device DPI( 436) or the universal one ( 438)?
[Nexus 4 Android Development] manpildo:
For what it's worth, I use Euphoria with Banks Gapps, have "wake up" and "keep awake" disabled in app permissions and now a nice "0s" keep awake is looking at me in battery stats for Google Services. Google Play services hasn't even made an appearance yet. Checking wakelock detector I have no wakelocks other than Play Music, which I use for music of course. Try Banks Gapps and in case you haven't disabled both permissions (you only mentioned one), then do it.

Btw, I think service/app killers might actually harm your battery more than do any good. Constant killing-waking is a power hog.
[Nexus 4 Android Development] Dor-b:
Hi, I know that euphoria rom don't have this issue, I have an lg g pad 8.3 running euphoria. Cm has patched this issue recently, any way in chroma there is only one premission.

I will try to remove play services from the service killer

Quanta Tweaks app suggestion

This is off topic, but I couldn't find a thread for Quanta Tweaks app. It'd be great to have a quick toggle widget. I use t this kernel and app primarily to toggle into exponential brightness mode and I wish it were a shortcut on my home screen.
[Nexus 4 Android Development] oxxshadow:
I still experience the music stuttering with Quanta kernel [MENTION=4217103]zaclimon[/MENTION] . Any idea what it could be?
[Nexus 4 Android Development] ObihoernchenDE:
Mhh even with v3 and cyanogenmod 12.1 mpdecision and power.mako.so aren't deleted/renamed :/ ofc I flashed cm 12.1 before. Something is still missing I think.

Is there anything I can so to help you to debug the problem?
[Nexus 4 Android Development] yochananmarqos:
I've not once had music stutter in the 2 years I've owned my N4. However there's occasionally an odd noise due to a hardware issue with the proximity sensor. I haven't heard it since upgrading to 5.1, though.
[Nexus 4 Android Development] abhishekjain.ims:
Hi guys, can you just confirm if there is also any wifi battery draining issue presented on this custom kernel because on stock kernel wifi draining issue is presented. If I switched on my wifi it keeps my wifi scanning on all the time which can be seen in the battery stats or by going to *#*#4636#*#* under wifi status.
[Nexus 4 Android Development] prithvic:
Its not the wifi bug. Its your phone scanning for wifi networks. To disable Go to advanced wifi settings and disable scanning always available. Your wifi shouldn't be scanning anymore. If you want it more strict then change this too > "keep wifi on during sleep - never".
[Nexus 4 Android Development] emanuele1986:
I had the same problem with the frequency. I updated the ROM to the cm12.1 nightly 04/22 with 5.1.1 lollipop and after i installed v3 kernel. The frequency in one core stay to 1026mhz as lower. I had to rename power mano e mpprecision file to fix it.
[Nexus 4 Android Development] zaclimon:
Hmm those isolated cases... looool. Maybe there is a reason as of why probably the element is copied, then deleted instead of being renamed. Let's try the old method to see if it fixes it.

Also [MENTION=4575477]oxxshadow[/MENTION] I'm a bit clueless as the issue. I don't have any music stuttering with my device. I can continue to see what's wrong. Have you tried to change the frequencies/governors?

[MENTION=5359817]ahoyboyhoy[/MENTION] This is a great suggestion, though I don't plan on adding any features right now until I fix all the QT "issues" first.
[Nexus 4 Android Development] desiromeo719:
Quanta v3 working like a beast for me. Not having the 1ghz CPU lock that was happening on v2 anymore. I'm on latest cm12.1 nightly...

Amazing kernel :)

Hi [MENTION=4217103]zaclimon[/MENTION] ,

Thank you for the Amazing kernel , as seen from the below screenshot my phone sleeps like a baby :)

Also sometimes, maybe once in a day the signal drops to zero and i have no network connection for about 3-4 seconds.

I have tried to grab a logcat and dmesg , hope it provides some information to you . Although i am not sure if its happening from the kernel or the ROM .

[Nexus 4 Android Development] zaclimon:
Radio and kernel aren't dependent. Something must come from either the radio or the rom you're using. What is your current rom?

Also for anybody that uses faux sound over here, do you see any problems with it at the moment?
[Nexus 4 Android Development] yochananmarqos:
No problems with FauxSound here.
[Nexus 4 Android Development] ferrocene:
Faux works great here
[Nexus 4 Android Development] spider623:
something odd, just flashed the kernel and i have no access to the sdcard any more
[Nexus 4 Android Development] shawnbrennan55:
If you were running an anykernel kernel (e.g. AK, HellsCore, Hells Doctor) then you need to flash your ROMs stock boot.img or dirty flash the whole ROM prior to flashing Franco, SaberMOD Franco, or Quanta.
[Nexus 4 Android Development] spider623:
.... when we said franco is moving to anykernel?
[Nexus 4 Android Development] manpildo:
No problems with faux sound. Quality/loudness profile + Viper4Android with headphone specific DDC = magic. I feel sorry for the average users, who have no idea how underwhelming the stock sound really is, it's really awful once you've gona all xda on your phone.
[Nexus 4 Android Development] spider623:
Dirty fixed it
[Nexus 4 Android Development] zaclimon:
Alright, the reason I'm asking this is because I got a report that microphone gain wasn't working. Though I didn't want to go through the code without searching some feedback.

Thanks guys :)
[Nexus 4 Android Development] manpildo:
Regarding microphone gain, I've been told that sometimes it's difficult to hear me on the phone (my voice goes quiet and then normal again). I wasn't sure what to make of it so didn't bother reporting anywhere, but maybe it applies here?
[Nexus 4 Android Development] nodnarb91:
Holy crap I needs to try that combo now, I'm with Chroma + Stratosk now. Looks like my combo needs a little QuantaV3 in its life :p

Btw, what theme is that? Looks legit.
[Nexus 4 Android Development] iskandar1023:
Try it and underclock like crazy, you'll never go back.

No theme at all, i only use MTNavbar overlay for getting solid navbar.

Oh okay nice. But your battery info is in white, Chroma has a dark background as its UI.

Oh chroma is using Timberwolf layers by default.

anybody can boot to secondary rom?

i can't boot to secondary rom, i think f2fs is the culprit but just to make sure :rolleyes:
[Nexus 4 Android Development] athibanvasanth:
Does Vomertweaks work with this kernel ?
[Nexus 4 Android Development] yochananmarqos:
Yes, however only the core management options work. Gesture controls are only supported on the N5/N6 with CleanCore Kernel.
[Nexus 4 Android Development] zaclimon:
Yeah f2fs seems to be the culprit. I was wondering if there could be a way for the rom to share the kernel like before. Unless it is automatically shared when installing.
[Nexus 4 Android Development] iskandar1023:
Or maybe my rom is? Chroma.

I've seen in chroma thread people can't boot to other rom with chroma in primary.

I'll try to swap chroma with another rom when i'm not too lazy maybe.

[Nexus 4 Android Development] athibanvasanth:
Thanks a lot !

Am using (Quanta + Franco.kernel updater + VomerTweaks + FauxSound/Speaker Loudness) and everything works flawlessly :)
[Nexus 4 Android Development] Persechini:
Hmm, I recently tried to install a second rom via multirom and also didn't manage to boot, also using f2fs for /data. But shouldn't it work after flashing the kernel in the second rom? I didn't test this because at the time I had only the aosp version of quanta on my device and the second rom was a CM
[Nexus 4 Android Development] zaclimon:
Normally it shouldn't work after flashing the second rom because the kernel doesn't support f2fs which is why I would like to know if it's possible to share the kernels from within multirom.
[Nexus 4 Android Development] tenfiftysix:
I am having a problem using V3 together with Chroma Rom latest. I can use Quanta tweaks to get to OTG with Nexus 4 with Ycable and am able to see all files. HOwever when trying to backup to external flash drive the external Flash drive is not recognized. Only internal storage.

Am I doing something wrong here? I am using Stickmount as well but one booting into recovery I cannot find external drive not even if mounting under advanced options

Please put me right here so I can backup to external with OTG and Y cable on Nexus 4

Thanks
[Nexus 4 Android Development] shawnbrennan55:
I replied to your post in the Chroma thread with a link.
[Nexus 4 Android Development] xenyz:
The way multirom works is that if you have the data partition formatted as f2fs, every kernel you use must have f2fs support, otherwise one of them won't be able to read the partition. Multirom just changes the mount points, but still uses the underlying filesystem.

You can 'share' kernels by just using the same boot.img as your main ROM, in the secondary ROM.
[Nexus 4 Android Development] keyra74:
i must be doomed with all custom kernel since cm12

i thought that factory resetting and upgrading to cm12.1 would solve my problem but no.

at first the phone is super fast and everything and after a few hour it lags like hell and the only option i have is to force a reboot so i get a working phone again.
[Nexus 4 Android Development] manpildo:
Sounds like a severe issue with memory leak. Have you checked what's going on in your RAM when it gets laggy?
[Nexus 4 Android Development] keyra74:
i'll check later this week if a logcat shows something

for now i'll stop using custom kernels
[Nexus 4 Android Development] zaclimon:
A more important question would be, have you tried anything else other than CM? The problem can come from CM and not from the kernels themselves..
[Nexus 4 Android Development] deedeeceleb:
Seems like there is some charging issue for me. Sometimes it shows charging with USB, while its plugged in the wallcharger. A reboot is fixing it until I replug it. I installed Franco Updater and activated fast charging
[Nexus 4 Android Development] keyra74:
i don't remember well but i was using rastapop or something before cm12 but it was more than 4 months ago ...

it's just so weird that it begins to lag after few hours and not just by being too hot or so.

i can confirm that i don't have the problem with their cm stock kernel
[Nexus 4 Android Development] mdaamir1989:
+1 on this issue. Been facing this issue with Quanta :)

I have plugged in my wall charger now and it says Charging with USB.

EDIT : Disabling and Enabling the USB fast charge option from FKU seems to fix the issue sometimes.
[Nexus 4 Android Development] ObihoernchenDE:
Had the same problem some days ago. Upgraded CM since then. But I didn't test too much to be sure. Will pay more attention now.

You should search for /system/lib/hw/power.mako.so and /system/bin/mpdecision and remove both files.
[Nexus 4 Android Development] zaclimon:
This USB charge issue is weird. If it's related to the fast charge, I only implemented faux's fast charge. Nothing more was done to it. Is the charging time the same as if it was plugged to a computer or the same as if it was charging on the wall?
[Nexus 4 Android Development] mdaamir1989:
The charging time seems to be the opposite. When connected to a wall charger it charges as if it were connected to an USB port without fast charge enabled.

When charging with an USB with fast charge enabled , it takes 3-4 hours to charge which shouldn't be the case. The battery screen still says charging with an USB when fast charge is enabled.
[Nexus 4 Android Development] keyra74:
i'll try that :)
[Nexus 4 Android Development] ferrocene:
So my weird issue is I lose cellular and wifi data when screen is off for more than 10 sec. Weird. Options are to keep WiFi on in sleep. Will comb through logs.
[Nexus 4 Android Development] gabidiesel:
Hi...just asking.... When you release quanta V4?.....thanks
[Nexus 4 Android Development] yochananmarqos:
Why, are you having a problem with V3?

FYI, it's considered rude to ask for ETA's.
[Nexus 4 Android Development] gabidiesel:
No problems...just .... Zaclimon...said something about possible release V4 on this weekend...
[Nexus 4 Android Development] zaclimon:
Where did I mention that V4 would be released this weekend? O.o
[Nexus 4 Android Development] gabidiesel:
Sorry...zaclimon....bad understanding....
[Nexus 4 Android Development] zaclimon:
Haha that's OK. I just didn't want to get false hopes up XD.

Also [MENTION=2558028]ferrocene[/MENTION] I don't understand how it is not working. I use the stock drivers and wifi is working perfectly for me. (I'm using Chroma as well)

I may try to revert to UBERTC 4.9 to see if the issues may not be related to that instead.
[Nexus 4 Android Development] ferrocene:
I'm not sure either. I'm still combing through the logs. I installed the 4/28 chroma and will give it a few hours stock to see if I can reproduce it, but so far it's working fine.

I have adaware installed and there are a bunch of errors with google ad services failing to reach localhost as that is how ad away configures DNS. I hope that's not confusing the OS to think there's no network connection. Still investigating.

[Nexus 4 Android Development] ObihoernchenDE:
Yep same here. For me a upgrade of my cm version did the trick. Before I've used the first 12.1 nightly.

[MENTION=4217103]zaclimon[/MENTION] the script still doesn't delete those 2 files (with cm). Maybe I can have a look at it if I have some time.
[Nexus 4 Android Development] zaclimon:
I do know that it still doesn't rename the files and I believe it's happening in recent CM 12.1 releases.. First CM 12.1 releases were working fine...

Anyways, I may try the old busybox method to get it fixed though. (Sometimes I'm asking why I'm even supporting CM at all... Too much changes -.- But oh well...)
[Nexus 4 Android Development] keyra74:
in fact it renamed mpdecision to mpdecision.bak but not the power file.

since i deleted them it changes to .bak :)
[Nexus 4 Android Development] NTLinhHaHa:
Does anyone else have the issue with the MTP mounting?

My Nexus 4 is on 5.1 , with busybox and without Xposed. Quanta is great, actually, but the only issue I have is that the device refuses to show up in my computer, therefore I can't copy files from and to the device. The phone still charges, which means it's not a cable issue. USB debugging works perfectly.

I don't use fast charging. I use Quanta for its dt2w and undervolting only.

Reversing to stock kernel fixes the issue (the device showed up immediately after plugging into the computer), but I need dt2w :crying:

Multiple kernel panics

[MENTION=4217103]zaclimon[/MENTION] ,

Im having frequent reboots due to kernel panic on Quanta V3. Running Euphoria latest ROM. Have got 2 lask_kmsg's if it is any useful.

The problem with these reboots is every time there is a kernel panic i think cache partition is wiped and it optimizes all my 148 apps every time.

Kernel panic 1 - http://pastebin.com/bwfzPWpU

Kernel panic 2 - http://pastebin.com/p9SK1VMR

Other tweaks enabled,

1. DT2W

2 Sound tweak (Microphone and speaker gain)

3. UV (This is not an issue because one of the logs was without UV , these reboots happened back to back and i don't have Enable on boot option checked )

4. USB fast charge
[Nexus 4 Android Development] svnhvn:
I think that come from the ROM side. I had exclusively using Quanta with Chroma and never had any problems whatsoever.
[Nexus 4 Android Development] maigre:
Not that this is the ideal solution for you, but you could use something like ES File Explorer or the like to make your N4 a FTP server. Then, you can FTP into the phone from your computer and make file transfers that way as long as they're on the same network. I do it all the time.

[Nexus 4 Android Development] tvisforme:
I have encountered a new issue with the v3 kernel, unfortunately. When it is installed (CM12.1 nightlies) the event log is quickly filled up with "PowerHAL: touch_boost: failed to send" error messages. These do not occur with the stock kernel.
[Nexus 4 Android Development] yochananmarqos:
That's always been like that on franco.Kernel (and therefore SaberMod / Quanta). Franco uses his own touch boost driver instead of PowerHAL, that's why you're seeing it. It can be ignored.
[Nexus 4 Android Development] zaclimon:
This behavior is normal. It's because we don't use mpdecision as there's a custom touchboost implemented in the kernel.
[Nexus 4 Android Development] tvisforme:
Hmm... Are you sure there's no cost in having hundreds or thousands of these errors flooding Logcat? I have also encountered a significant slowdown/lag in the past few days with V3. Wiping /system and reinstalling doesn't cure the issue, but restoring the stock (CM12.1) kernel does.
