Franco, do you intend to keep a calibrated version of the kernel something like r10 and r11 for a while? I read a few pages back some criticism of it since it seems this phone ships with 2 different panels but whatever one you got, it works great on mine too as well as a friend's..

I love it, I think it makes my screen that much more beautiful!

Still on r11,

appreciate the heck out of your daily (hourly? minutely?) updates as always :D

I know this isn't a request thread, but I think you should at least consider the double tap to wake thing as well, it would definitely save a lot of future hardware failures from constantly pressing that button. I know it might be low on the totem pole of priorities though, if at all.

forever a fan, your name is synonymous with the nexus brand, and I started acknowledging your work with gnex, when I had that phone (was my first 'droid')

As I said before, once I have time to finally crack the gamma registers it will be all default colors.

Double tap to wake is not my priority at the moment, but its surely something I can see me adding once I have a little more time.
[Nexus 5 Original Android Development] tyrellcorpnexus:
Thanks again! :good:
[Nexus 5 Original Android Development] ganeshp:
I think flar and showp are already working on it.. Once they got it working completely you can add it of you want to that is

Also did you try minion rush game? (it's a free game) It's lagging on this kernel. On stock it's fine though.. This might be kept as reference point for gaming performance as it's demanding more? (or badly coded?)
[Nexus 5 Original Android Development] sordna:
Do you like KitKat ?

Francisco, do you like KitKat ?? It's the first time I feel disappointed for a new android version.

The new keyboard is terrible, gray looks bad and long-pressing the dot shows half the characters it had before.

The status bar wifi icon gives you less info now, and worst of all App Ops is removed !

EDIT: And the new alarm sucks monkeyballs, you can't set the time you want unless it ends in a 5 and it's confusing as hell ! Totally ruined.

sorry for being a noob but i need help.. I know that its being asked before but I was trying to download the FKU beta. I joined his community, followed the link, but it takes me to a page that says that im a tetser but when i click the link it takes me to the playstore, to the regular FKU app..
[Nexus 5 Original Android Development] :
You have to buy the FKU app first.
[Nexus 5 Original Android Development] franciscofranco:
Depends if I like their code or not.

I haven't tried minion rush. you say it lags on r12?

KitKat is fine, but I was hoping for more visible changes and some improvements regarding apps permissions to hold wakelocks for example, or some improvements to how Android delt with apps that wakelock for long periods of time, or maybe fix their Google Services to not keep polling for **** during screen off.

Yeah App ops is not there :'(

[Nexus 5 Original Android Development] beaver2233:
is this not app ops? or am I mistaken?
[Nexus 5 Original Android Development] Tzfardaya:
Yes and no.. They change the requirements for cores 2 and 3 to online...

If stock works for you, then no need to change them...

Thanks [MENTION=4437173]Piereligio[/MENTION]

I'm loving V7 and I prefer it over stock settings.

However, I was wondering if you have read AnandTech's review of the Nexus 5 and what you think of his analysis since he praises the display in stating:

"In addition, the Nexus 5 has none of the saturation boost that’s sadly quite pervasive right now, instead giving the right evenly spaced saturation stepping on its color channels. The Nexus 7 has slightly lower Delta-E, but it’s clear to me that Google has made color calibration an emphasis on the Nexus line."

"The end result is easy to sum up, however – Nexus 5 has the best calibrated display I’ve seen so far in any Android handset."

Dude...let me introduce you to MultiRom...I've got stock as my daily driver, and if I feel the itch I flash to another ROM ...even bought a Minova to flash to USB....
[Nexus 5 Original Android Development] Piereligio:
Yeah, I heard something about it.. But I don't know how much trust it. I mean that stock calibration even has some banding, it's washed out, warm, and if I remember it has greys not exactly neutral... Mine it's a bit cold (but I like it like it is).

Anyway stock calibration seems like giving more detail, sometimes.. But I obviously use my profile. Don't know why, but stock calibration feels like having a cheap panel.

[Nexus 5 Original Android Development] Tzfardaya:
I finally got around to putting my colorimeter on my n5.. Compared a couple calibration settings with it.. (stock and pierreligio v7 among them)

Stock was almost dead on with regards to sRGB colour rendition, only fell flat with gamma... (the highs are brighter than they should be)

Pierreligio v7 was all over the map.. looks great, but gamma band was an inverted u, too saturated...

So while pierreligio's setting looks great, but a sRGB or d65 calibration standpoint, not even close...

I've put my hcfr (pc/Mac app has been linked repeatedly in the thread) results filed in my d-h.st page (link is in my signature) is anyone wants to see what I mean...

Pierreligio, please, don't take this as a criticism, I love how your work looks, and I know you're not trying for srgb or d65 calibration...
[Nexus 5 Original Android Development] ChazzMatt:
Yeah, in TV terminology stock black levels suck. On a vector scope, colors would be "accurate", but on waveform scope the black levels would be too high -- which causes the picture to look washed out.

Guys I just want to mention something regarding battery life and performance, that I feel hasn't been given the proper attention: Force GPU Rendering (saw from [MENTION=4788174]Nbsss[/MENTION] 's settings) . I've tried a couple of cycles with it enabled and gpu UC to 320 MHz, and the overall UI smoothness is much better (especially in apps like Facebook, Google+, Maps, etc), as well as some of the apps' graphics look better. Also the battery life seems better. Got through a day with almost 3hrs screen on time, almost 2 hours music playback, over 16h up time, and am still sitting on 39% battery – almost all time on LTE.

Overall usage was music (poweramp), very light gaming (super hexagon), news reading (feedly), some browsing (chrome beta), chat on facebook messenger. I'll post my settings and screenshots below (using slightly modified [MENTION=3473030]Gingerbread Man[/MENTION] settings:

Welcome to the small niche club of us!

I must admit iv been using your v7 since and it does look great, thanks! I know its tough to make a good profile having done a few myself!

Yup there's 2 approaches, what looks good to the eye which is good enough for most people and then the scientific approach.

If you have time it would be great if you could help out [MENTION=520365]Yoirci[/MENTION] as he's going full scientific and I believe is looking for help from someone with the proper equipment.

I suspected that I had made it a bit too contrasted, effectively. I don't have the instruments to check it, I only use my eyes. Could you check for me the white point value that can make reach a good gamma?

Anyway for people that doesn't like the gamma, u can just tweak the white point value. Even I have changed it (just now), from 32 to 33 or 34 (still undecided).
[Nexus 5 Original Android Development] Hatshipuh:
I'm curious how Mag01 settings comes off, which has been my standard profile for ages, since it seemed to me like stock but with better gamma values.

Also tried Piereligio's settings, but even the latest v7 seems to me to have blueish whites when I look at my screen outside. Other than that I loved that profile, but still went back to Mag01 because of the whites.

You are right....well i didnt see much difference in battery life...Now 3 cores are on and input boost was reduced to the 1200 step...:good:
[Nexus 5 Original Android Development] franciscofranco:
Yeah there isn't that much big of difference in battery life either using 4 cores on 2 cores with screen on. These Krait cores are pretty efficient and they all enter Retention state regardless which didn't happen on previous Krait revs.
[Nexus 5 Original Android Development] laureanop:
Morfic contends that all cores on at all times is more efficient

Show- p1984 (bricked) contends that it's a waste of battery ( I've used his kernel and it does race back to one core quickly)

Are you still in the middle about this or are you starting to lean more towards using all cores while screen is on?

How did the experiment of running all cores at a lower CPU speed turn out??

Huh. I'm getting more battery life with only 2 cores on, rather than all 4 on.

Hi guys.

I follow this thread very closelly and all the times someone comes up with some kernel settings for GPU, CPU, and hotplug/governor tweaks that are supposed to save battery life, while retaining the smoothnes of Franco's briliang kernel. Yet no one posts other things like what ROM you guys use - that can play a huge role in battery life. Also do you tweak display brightness, because that is the biggest culprit for battery draining. I am saying this, because I recently discovered that the stock launcher coming with stock ROMs has google search running all the time, and that was the second biggest drainer for batery for me (first was youtube).

I personally use stock settings for the kernel, sometimes trying some settings you post, with no difference in battery life in my usage scenario. Also I use YAAB app for controlling brightness. Best result so far for me was around 4h SOT with mostly using youtube app/facebook/facebook messenger and tapatalk.

So my question is what am I doing wrong, or am I missing something?

I don't want to sound rude or anything like that, so if I offend someone, please forgive me, english is not my mother tongue.
[Nexus 5 Original Android Development] willgare:
Hi, from what I know - the ROM plays very little part in battery impact, and as long as you disable all the Google now settings, with the right configuration, you can achieve 5hrs + screen time.

I personally do not get more than 3.5 to 4, but I prefer to have the brightness quite high.

The difference between stock and Franco cannot be any greater, Franco has mastered the art of battery survival with his Kernel, something we should all be very grateful of.

My current setup is:

ROM: Stock

KERNEL: Franco 37 (set and forget settings)

Bionic + Dalvik Patches

Jishnu Camera Mod

Many system apps removed

Modded Colour Profile: Pierligio V7

With the above, I have never been happier with my phone.
[Nexus 5 Original Android Development] danieljcf:
In my case, this happens with stock kernel too. And looks like it affects more people. The workaround of locking wi-fi to the 2.4GHz band is working for now.

edit: hmm nope, still happening. We'll have to wait until Google fix this :(.
[Nexus 5 Original Android Development] fbf2201:
If some userspace stuff prevents the phone from getting into deep sleep, that plays a huge role.
[Nexus 5 Original Android Development] Hatshipuh:
Thanks for the test!

As I understand, Mag01 is pretty close, and cyan color temperature is too warm? But never thought that Pereligio would be that much colder.

Although I don't really care about accurate colors, guess I picked my profile pretty good, though I know it's still dependant on the individual panel.

Now it's time to make perfectly accurate profile! ;)

Except there is a hidden gem in the existing ones, honestly I didn't test all of them.

I'm also interested in 0rigin, Neriamarillo v1 - v3 and Nexus5Mag, because they are pretty similar in my eyes, slightly colder I guess, but with better Gamma according to Display Tester.
[Nexus 5 Original Android Development] Tzfardaya:
The 2 big setting posters are [MENTION=2918197]The Gingerbread Man[/MENTION] (who uses stock) and [MENTION=1363323]vomer[/MENTION] (not sure what he uses)

But, how you use your phone is almost as important as what settings you use.

If you're always using apps that let the phone stay in lower frequencies, then Many of the changes won't have much effect.

---------- Post added at 05:32 AM ---------- Previous post was at 05:29 AM ----------

I do plan to go through them all and test them... But I'm not ready to tweak a profile yet.. Still want to see which profiles are the most color accurate and see how their settings differ... I'm still learning, not yet ready to try implementation yet. :P
[Nexus 5 Original Android Development] franciscofranco:
I'm not leaning towards anything in particular. The default setup of this Kernel is two cores always online and then users can choose whatever they want to run. I think 4 cores always online during screen off is just ok as any other setup but its always dependent on the governor settings. Using more cores online the load will be better distributed and theoretically will balance things out in terms of frequencies used, but if the governor is very aggressive in using higher freqs then you'll be screwed. If you get two devices with the exact same configuration and you test 4 cores online vs 2 cores online of course the 2 cores will always give you better battery in the long run for obvious reasons, but then we're all grown ups and can make our own choices in how we want our phone to run. I run with all cores online with max freq uncapped but because I don't care if I get 1 hour less of battery life (theoretical number) by the end of the day.

You're doing something wrong sorry. Any Kernel that you'll use will do the same because camera driver code is 100% stock. You probably have, just like tons of users, some **** that is preventing the camera from being used. That's on you.

Thanks.
[Nexus 5 Original Android Development] brown_89:
Sorry guys,what's the best settings in fku for perfomance?
[Nexus 5 Original Android Development] ChazzMatt:
I want color accuracy and proper black level. It's not a choice of one or the other.

In the TV studio we calibrate monitors to have accurate color, video levels and blacks. If blacks are to high on the scope, the picture is washed out, no matter how accurate the color is. Still a FAIL.

These phones are also HD VIDEO displays, so it's the same as our studio HD displays.

You need accurate colors and a crisp blacks to show have realistic reproduction of what you see in real life.

Stock gamma on these phones is far from optimal, while still having accurate color. Don't settle for half.

Performance governor.
[Nexus 5 Original Android Development] big_adventure:
If you are getting lag, you are probably getting throttled. Many people run Asphalt 8 with a reduced speed per-app mode, and it works fine like that. Try running it with CPU capped lower and throttle temp bumped up and see what happens.

No current mobile games need everything this phone can throw at them. But many will use everything available, and this will cause thermal throttling in many cases.

---------- Post added at 03:11 PM ---------- Previous post was at 03:08 PM ----------

You really need to give more information there. Franco's answer "performance governor", is correct but a little glib. :) You won't get much battery life if you try that. Stock settings should be faster than anything you'll need.

Apparent UX performance differences will come from reducing animation scale in developer options. Avoiding thermal throttling is also critical. good luck.
