[Q] Can the Nexus 4 display true black? - Nexus 4 Q&A, Help & Troubleshooting

Hello everyone, I was wondering if our device can display true black. Just wondering as I am wanting the status bar and navbar to kinda blend in with the rest of the phone if you know what I mean. It would make it look even sexier than it already does.

I'm sure if you tweak the gamma control settings it can be true black

I have no idea why I didn't think of that haha. Thanks I'll have a try now and post results if it works, might as well

Ah well... Spent nearly an hour messing about only to find out that it's only super amoled that can display true black makes me want to murder some pixels to make it look boss. :silly:

Awesome Color Calibrator from the Nexus Forum!

This allows you to adjust the RGB Screen Colors. Check it out. Works on my EVO:

What are your settings?
I only got Force Closes when trying it out...
This has been around forever, I also got Fc's trying to use it.
I have CM6 RC 2, works fine
just was wondering the setting people with EVO's are changing them to
This is built in Cyanogen Mod too.
Settings/user interface/render effect.
Can also be applied as a widget.
It helps a good bit, if you compare non-calibrated and calibrated, without calibration the colors look too washed out and not as dark and deep.

i want dark and deep, what are the settings to get it like that?
Well, this adjusts RBG but it doesn't adjust contrast for blacker blacks or color saturation. Basically what it will do is make your colors either warmer or cooler. Just play with it till you find one you like. If you want a more 3d effect, choose wallpapers in soft focus (or do it yourself using Photoshop) and icons will appear to "float" above the background.

Sorry, I had to. lol. Neat app!
thats pretty cool
I just tried the built in app in CM6.1 and it really gives my EVO a different look. Im using the N1 Low setting.
I find just N1 Calibrated (not cool or red) works best. It really does make a good bit of difference too, try watching a video with it off and it on. The colors feel a bit richer and more natural with the calibration.
I couldn't go back to keeping the default settings anymore
I agree that N1 is best on my EVO. Seems to make the blacks blacker which always makes the screen appear to "pop" more.
However, these are pre-settings. Wit the tweak I mentioned in the OP it is completely customizable. Anyway, whatever works for you.
Posted this in the other thread, but does anyone else get a green hue when scrolling (it's easiest to see in something like the "settings" menu when you scroll).
Any idea if this is correctable?

Why are my icons low-resolution?

I'm running Paranoid Android 2.16 and the settings I'm using can be found in the screen shots below. I've adjusted the dpi, so maybe that has some sort of effect on the icons? The text is still very clear, but the icons appear low resolution. Maybe you guys have some suggestions how to adjust PA so that I can have the tablet interface/homescreen, small text, while maintaining high res icons? Thanks!

I updated it with a comparison to my One X. I know I've become a bit spoiled with my One X, but the icons, especially on the Nexus vs just looking at a screen shot seem to be a bit blurry.

Why backgrounds in SGS4 are write?

I've got used for black/dark background in several years.
But in reviews of SGS4 i see that many apps/settings have white background. I just wonder if there is kind of theme switch in SGS4 to get already convenient black background or now we are stuck to white now?

The switch is called ROOT and Custom Rom.
I'm wondering the same thing. Given that the S4 sticks with Super AMOLED, this seems like a poor decision -- this white theme. Unless, of course, there's some sort of theming taking place, which I doubt else it would've been taken note of during launch. Although they can still change things from now until April 25...
I really hope we can change this white without custom ROM.

You would have to edit every apk for each app you want to change and make them use the device.default theme / halo theme instead of the device.default.light / halo.light

It is because the black/dark theme was the biggest **** ever. Amoleds aren't the brightest and gray text on black background ...... Seriously??? The inbox was virtually unreadable. While emails were unread they had white text on black background and that was OK. Once read they were some tone of gray on black background. In the car and outside it was impossible to make out anything. I had a shortcut on my home screen to enable the accessibility /negative colours specifically so I could read my inbox when it was it too bright where I was.
Admittedly they should just give you the option for me the bright theme is a very welcome change.

how do you know they're not comparing their early unit with the latest octa?
look it up on GSMArena, they had one of those early units with the white background, and then when they got the final one with the black backgrounds they did their tests and reviewed their review of the early unit. I still am pretty sure the latest firmwares do not have white backgrounds. look at the XDA post your battery results thread for example, all black.
I don't know why you're being so rude. do YOU have a store bought S4 with a white background?

all white theme on 5.0 lollipop?

Seeing some of the review videos on lollipop, including the Nexus 6 review, EVERYTHING is white on lollipop! The notification drop down, the background for all settings, and even the app drawer!
http://link.tapatalk.com/api/click?...rs.com&subid=cfcd208495d565ef66e7dff9f98764da
Besides being ugly as sin, that's going to be a significant drain on the battery! With the nexus 6 using an amoled display, why would they implement something so counterintuitive? One of the beauties of the moto x is how all the menus, app drawer etc look so elegant in black. On top of saving display energy usage.
I've searched everywhere looking to see if the theme would be customizable and there's nothing to suggest so. Comments?
I wouldn't worry about it. I don't think anyone spends a big amount of time in the notification area, drawer, or in the settings

There is an xposed module to convert white holo to dark, and probably it will convert white material to dark. On LCD white looks better but on AMOLED I prefer dark too
Afaik there will be dark theme for amoled.
I don't know where I read it but I read it somewhere. A few weeks ago.

Well it doesn't take an engineer to know a light background that requires an amoled screen to display uses more energy than a dark one where the pixels shut off. But that's that I suppose..
I'm running the latest preview on my N5. Yeah, it's white. Battery life? Much improved. Surprisingly so. I've no doubt the improvement in battery life will carry over to the X. I know there isn't a whole lot of room for improvement in performance on the X but it has made a startlingly difference on my N5. Sucks your not a fan of the design but for those of us that like it, it's an amazing upgrade. One I can't wait to experience on my X.
Edit: I understand your concern that the difference in display technologies will make the improvement in battery life mute but I can't imagine white backgrounds making that big a difference.

I'm not. Do I spend two hours or more in the notification shade at one time? no. do i spend 2 hours or more just in the settings? no. do i spend 2 hours or more on the google launcher app drawer? no. people need to relax, it won't be THAT bad. i am sure many of us are in apps that are light in color
edit: there are other factors that decrease battery life. i doubt you're constantly on a white screen for long periods of time. even with it being white, i am still sure amoled consumes less than lcd

i am all for opinions, but the OS being white shouldn't "freak" everyone out if you have AMOLED screens. i interpreted your first post wrong and thought you were very upset to the point where you'll rage , hence why i said some need to relax a bit. i still stand by my opinion that i don't think battery is going to go down the drain. remember Project Volta, maybe that'll help a bit too. good discussion :good:

The battery aspect is secondary to me. It just seems counter intuitive to make a nexus device with an amoled screen and widdle down one of the big benefits of it.
My main concern is IMO its ugly as all hell. Material design looks fantastic. But the white folder type backgrounds reallyblook out of place and dated. Of course others may love it. I just hope/wish they give an option for a dark theme..

i am on the fence with it. i agree, white isn't a good color, but idk if black would be a matching color for the home screen. heck, why doesn't Google just allow us to change the background app drawer page to whatever color we want. problem solved . looks like i will just have to endure the white (at least it isn't completely hideous lol)
Material Design is gorgeous. My eyes will be happy once devs get on top of that, not just Google

Exactly. I think by this iteration of android we should be able to have a color theme choice. Or an inversion mode to black out whites.

Want accurate colors, but cool whites like LCDs? UPDATE: No longer works in 5.1.1

HDxDaniel discovered this trick on the Note 4, but it works great on the S6 as well. This hidden screen mode gives you accurate colors like basic mode, but cool whites like adaptive mode. It's great for those of us who don't want super saturated colors, but also don't want super warm whites. This screen mode basically makes the S6 screen look like an iPhone or Nexus 5 screen, so if you came from either of those phones, you'll probably like it.
Here's the thread detailing how to set it:

Good find, Thanks for sharing
Looks like it needs to be set again each time you reboot. A little annoying, but not a huge deal.
Interesting!
Works great. Don't understand why this is hidden. I love basic mode but those whites have really bothered me. This new mode seems a bit too bright but I suppose I just need to get use to it.
The white do look better, but I think it makes the colours look washed out.
Nice find. Looks pretty decent.
So it's clear to me after some testing that the colors aren't quite as accurate in this mode as basic mode (reds in particular), but they're much closer to accurate than any other mode apart from basic. I suspect this is because this color profile was designed for a Galaxy Tab AMOLED screen with slightly different characteristics.
I wish we could create our own color profiles. Any devs tried finding the included ones in system or in the kernel code?
