If people want blown out colors that is fine; it is a preference and everyone has theirs. However, it is not accurate. One of the things I disliked about my SII was the blown out colors. It is great if Franco wants to give people blown out colors (given Samsung sales, it seems many people like this), but those of us who dislike the trend should have the option to use Franco's kernel with more accurate colors.

I agree with this statement and what you said about the colours (too dark).

r69 colors are *much* better than r68 but they are still blown out. Back to r67.

Re: [KERNEL][GPL][N4] franco.Kernel - r53

I'm still rocking r62. My favorite so far. Fastest and best battery life. R68/r69 are also a little off too me. Maybe its just me because I don't think the colors on stock are washed out...to me they look great Lol and I'm also coming from an amoled.
[Nexus 4 Original Android Development] jack1984:
Re: [KERNEL][GPL][N4] franco.Kernel - r53

I'm liking the contrast on 69, it seems to be an improvement over Franco's color settings if only because of the adjustments made in gamma, but I definitely prefer this over 68's overly saturated tones. Thanks Franco!
[Nexus 4 Original Android Development] Hanny:
im totally satisfied with r69's colors as they are not dark anymore!! 255,255,255 is still tinting yellow therefore i remained on my beloved combination 230,228,240. But with the same combination, r69 does show an improvement over r67 as the whites were a very little bit reddish before that I couldn't find a way to get rid of. r69 has helped me complete the task.

and for the cores i think im having some more input here after more testing.

1. about the keyboard typing

i dont know whether if im typing extremely fast or not, the feeling of typing gradually varies from "heavier" in hotplugging mode, "moderate" in dual core mode and "completely light" in quad core mode. Light means theres zero delay after you type and you feel "light", thats the only word i can use to describe the feelings from my fingers.

the keyboard may matter as I am using GO keyboard (need to type chinese sometimes). needless to say AOSP keyboard must be smoother than it and it is. but changing to AOSP keyboard just shifts the overall heaviness a bit lighter, while the little delay feeling was not eliminated completely in hotplugging and dual core modes.

at this point i am questioning myself how did i not feel typing lag before r61? i dont know. maybe im too getting used to r61 for a week so i just cant leave the feeling of lightness.

2. about throttling in games

i realize that quad core mode is not only for buttery gaming while its not throttling, it also helps to maintain smoothness while throttling, which the 4 cores are steadily at 1026mhz. on the other hand, yes - when the device is hot while using hotplugging or dual core mode, and playing NFSMW, it definitely lagged. for hotplugging, unnecessary core on/off line management has made the device dont know what to do to maintain smoothness, while for dual core mode its simply not enough power for 2x 1026mhz to support such intense graphics.

that being said, quad core mode 4x 1026mhz has been perfect enough to maintain the buttery smoothness given by [ 2x 1512 + 2x (384 to 1350) ] in quad core mode. i suggest the "locked cpu speed" could be 1026 in regard to your idea here that i totally second:

currently, the coolest workaround to achieve such results (cpu getting locked in intensive games) is to lower the thermal throttling threshold to something between 53-58. that wouldn't affect the cores ramping up to 1512 in daily usage, while maintaining the throttling 1026mhz after 5-10 minutes of gaming. as a bonus, it also protects the cpu more. best of luck on your way on finding GPU busy status, franco :D

[Nexus 4 Original Android Development] molesarecoming:
it doesnt blow out. its designed for a little less rgb

kcal_r = 245;

kcal_g = 244;

kcal_b = 240;

franco has probably used it with 255/255/255. as some have said here, dial back and youre good.

if you still want more detail in the whites: #define g_white 0x40, not 39 --- then its using the same whitepoint as google again. 2nd rev is using a slightly smaller whitepoint.

overall, with the rgb values above, this is more accurate than google can ever be. simply because they're working with a crippled bluechannel, its impossible to be accurate when youre working with two colors instead of three. heres what anandtech had to say "I’ve mentioned that Google continues to struggle at calibrating their displays. [..] This continues to be the case with the Nexus 4. [..] I’m convinced the results that we’re getting out of the Nexus 4 basically represent no attempt at calibrating the display, and as a result the numbers suffer." the panel is miscalibrated, whatever you say, its not "preference."

Re: [KERNEL][GPL][N4] franco.Kernel - r53

One question, do you guys use a IPS monitor for your computer? The PA colours are not life like, but maybe that's the goal.
[Nexus 4 Original Android Development] Bar81:
Thanks. I will try these settings. Edit: Better, but still off. r67 is still best.

---------- Post added at 01:43 PM ---------- Previous post was at 01:41 PM ----------

Yes, I am typing this while looking at an IPS monitor (HP LP2475w). If that is the goal, then that is further argument that they should be an option in addition to the standard colors.
[Nexus 4 Original Android Development] revamper:
Re: [KERNEL][GPL][N4] franco.Kernel - r53

Franco used it with the rgb values you just suggested. I personally think it's a MASSIVE improvement over stock.
[Nexus 4 Original Android Development] Bar81:
The fact that the values are still being tweaked lends credence to it being preference (or else the r68 colors would have been perfect). All I want is colors that look natural (i.e., like real life), not overdone colors.

I think r69 is a huge step in the right direction and is not wildly off, particularly with the color tuning options I quoted from the other poster, but the colors are still a little overdone.

I like Fraco's kernels alot but the situation is similar as above. I always experience some small lags using the kernel. I have tried many versions since few months and it always appears on Franco's kernel. I don't know why and I would love to find a solution, because battery life is great on it. Maybe someone has any tips for tweaking governor controls or anything else?

That would be awesome to try.
[Nexus 4 Original Android Development] Arstoien:
Probably because you're using the default settings (hotplugging).

Use "echo 0 > /sys/module/auto_hotplug/parameters/hotplug_routines" (without the quotes) to disable the hotplugging and keep 2 cores online – no more, no less. Then you can use "echo 1 > /sys/module/auto_hotplug/parameters/quad_core_mode" to online all 4 cores. Do the same line with 0 instead of 1 to switch back to two cores, if you want. I use Tasker Widgets to toggle between them. When Franco releases the nightly build, he'll include an option in his program to toggle between them. That's if he decides to keep these three modes, I assume.

For me Hotplugging is a little bit laggier than Dual and Quad Core Mode. Maybe that's why you're experiencing some stutters.

I don't know why some people think the new colors are too much?!? Maybe you to used to having a faded washed out screen out the box.
[Nexus 4 Original Android Development] Arstoien:
Here's a zip with three apps I exported with Tasker – one to activate each mode. I used franco's app icon to theme them up :) . I've tested them and they work fine. They require root.

All they do is run the lines franco said in his post and briefly flash a message saying it's done. You don't need to run them in any particular order. Note that you need to turn off and on your screen for changes to take effect. Hope that makes things easier for people asking how to switch.

EDIT: Zip updated with new names for the apps, so they stay together in the app drawer. If you installed the previous ones, you can uninstall them.

Re: [KERNEL][GPL][N4] franco.Kernel - r53

The color calibration stuff is always going to be off unless you match it in RGB and gamma values to a properly calibrated (ie. with a hardware calibration tool like the ColorVision Spyder) screen on your PC.

As someone who works with professionally calibrated monitors every day I can tell you the colors currently are not anywhere close to correct when it comes to white balance, shadow and highlight detail and saturation. These settings can be fixed if we get the required interface, but r68 and r69 are hard coded which isn't going to be the case for long I hope, since they don't match any standards.

Please take this feedback as it's intended - I want to see correct color more than most and look forward to a full interface in the kernel for making it happen, since I carry my photo portfolio on my phone and have a need to show clients the proper image with good shadow detail and contrast, along with accurate colors.

Cheers for your hard work Franco!

Hotplugging is laggy for me too. Even dual-core more is smoother than that. Is it not possibile to have a mixture of the two in which 2 cores are online all the time (1 core when screen off) and core 3 and 4 come online only in the moment when the load is that high.

[Nexus 4 Original Android Development] Zoccat:
Tested r69 colors, indeed the intense oversaturated colors are allmost fixed, would be ok for me now. But the screen is still overall somewhat darker than r67 and prior kernels, though not as much as r68. Is personal preference territory we're into here, myself likes r67 colors (with 230, 228, 240 colorprofile settings) better than r69. Am using the changed cfq settings from r68/r69 manually configured in r67. Battery in r67+ seems to be better than in r61/r62.

Would appreciate toggles/switches in Franco app for 2/4 cores modes.

Re: [KERNEL][GPL][N4] franco.Kernel - r53

I just wanted to let you know that you can downgrade the touchscreen driver to get a MUCH more sensitive touchscreen. It's 1 command, takes about 15-20 seconds (screen won't be responsive) , and is reset when you reboot or go into recovery mode (not permanent). I think you can add it to a startup script if you want, but I just run the command with a shortcut after I boot up (which isn't very often).

Anyway, here's the file:

http://db.tt/aOtxzXvm

and the command is:

echo 1 /sdcard/SynaImage.E015.bin > /sys/devices/virtual/input/lge_touch/firmware

Put SynaImage.E015.bin in /sdcard/ (or modify the command). This made my n4 much more enjoyable to use because it's just as (or more) responsive as iphones and ipads and nexus 7's now. :)

[Nexus 4 Original Android Development] iammudd:
You're one of the few who aren't focusing solely on colour. :) After Franco described how much overhead hotplugging required and that there was a chance that the net effect on battery for having cores constantly-online would be tolerable, I decided to switch over to his kernel permanently (for his non-mainstream thinking alone).

Performance while flinging with 4 constant cores was instantaneously noticeable to me. (I was surprised to read complaints of under-performance of both r61 and r62. For me, hotplugging a new core actually caused lags.) So my question for the ppl who prefer hotplug is whether they simply preferred hotplug from 2 to 4 or did they really want 1 to 4 (perhaps because they experienced higher battery drain)?

If it's not easy to fetch GPU status, perhaps min freq locking can be based simply on how many cores are already online. Or perhaps when a core is brought online, it's auto-ramped to a high-freq (and its governor can decide to ramp it back down if necessary). After all, requiring a new core is already an indication of load. And sorry to drag this up again but re: freq sync actually causing poor performance,

It's funny that when we talk about better color reproduction you immediately assume Samsung's AMOLED level of saturation.

Remember: LG made all the IPS screen for Nexus 4 and they KNOW how to calibrate THEIR product. Google messed up the calibration, it's a fact, therefore your whole argument of "accurate colors of Google" is in fact, moot.

My suggestion: have an open mind and give each setting at least a day. Or if you have professional calibrating equipment, such as Spyder4pro or X-Rite, please try them on your N4 yourself.

Flame away.

Perhaps franco can post a sample script (if user-modifiable sys variables are used in his kernel).
