Anyone know if the true HD IPS+ screen is similar to the AMOLED in that black pixels dont use as much power? For example, would we have the same power saving benefits of black wallpaper and inverted apps as a phone with an AMOLED screen?
Nope because the LCD tries and replicate black's SDI the screen is still on and using power

I don't know, are you sure? I would be willing to bet that even though power is used to emit something, it's only a fraction of the power used for bright colors.

As far as I'm aware, LCD is still continually and constantly backlit, unless you have one of those dynamic backlighting schemes like on some TVs where there are zones that dime to provide blacker blacks. The backlight is a separate source as LCD cannot emit its own light.
OLED provide the source of the light as well as colour, so when the pixel is black, it is actually off.
So, REDFOCZ's response is correct.
AMOLED screens don’t require a backlight. The benefit of losing a backlight is apparent: these screens are able to produce blacks so deep that the screen pixels can shut right off. This can save battery life if you use a background that is dark in color or black. LCD screens still require the back light on those using power.

Hey everyone, normally there is a setting under development that you can put a check to leave the screen on while charging the GSII. I looked and no box to check. Anyone know if there is a different way to do this on the GSI?

Probably not a good idea. AMOLED screens can suffer from burn in. Likely why Samsung removed the option. Many Nexus One owners will testify to this because they have a faint image of the Froyo notification bar forever on their screen.
Sent from my SAMSUNG-SGH-I777 using xda premium
Correct. Burn in is a real concern on any OLED/AMOLED screens as blue pixels have very short life span. Don't leave it on for extended period. Don't use the max brightness all the time.
Thanks everyone. That makes sense, they removed this option from the phone. I always use the Auto brightness on my GSII. I did always use this option on my Nexus S to leave screen on while charging.

I use screebl from my htc inspire and it seems to work good on this device.
Inspire is a LCD screen and won't get burn-in. DON'T do it for any OLED/AMOLED screens. You get burn-in very easily.

I've left my Cappy AMOLED screen on for hours at a time and pretty much always while charging. I've never had (or heard of) any issues with burn in. Is the AMOLED Plus on the SGSII the issue or am I just lucky with my Cappy?

Sometimes you will have to be on special background to see the effect. A lot of Captivate onwers, Galaxy S owners and Samsung Focus owners found out the hardway. Just search screen burn-in in the respective forums. The blue pixles used to be only 2000 to 4000 hours of life span. I'm pretty sure Samsung has improved it to something like 8000 to 14000 hours but there is no specifics released by Samsung. So, you can count those hours to see how that will affect your screen burn-in.
Some phone screens get burn-in quite easily than others. So there is manufacture variations as well. I personally don't want to risk it. It's easier to get burn-in on these screens than today's Plasma TVs which typically has 80,000 to 100,000 hours half-brightness lifespan, or 10 times less likely to get burn-in than our phone screen. And TVs usually display motion videos instead of static text on the phone.
Thanks for clearing it up. Agreed--I do not want to risk it.
Have been searching around to see if there is such a thing, but I can't find anything. Does anyone know if it would even be possible to make an app to make screen brighter than the factory max setting? I know it must depend, at least to some extent, on the hardware... but I doubt they actually max it out at the factory... i'm just sayin =) would be nice to have in bright sunlight!

I would imagine you could increase the brightness by upping the voltage of whatever controls it, but I'm not sure if there is a hardware cap or not. I doubt it would be very safe for the hardware though...
yeah good point... i have no idea but wanted to see if anyone else did! i guess you would probably have to worry about "burn in" or "imprinting" ( I guess it would be called) too...

No, because it's only the backlight. But it certainly wouldn't be /good/ for the phone at all. But I haven't developed anything for the phone, and am somewhat new to the scene, so don't take my word alone on it

AMOLED screens don't have backlights.
It's not so much burn-in you have to worry about as burn-out - the individual LEDs are prone to do that if they have to display the same image or colour for long periods of time. Blue, for example, will burn out the fastest. There's a lot of discussion that went on around AMOLEDs for the earlier phones that used the screen tech, like the Nexus One and the SGS.
As for decreasing brightness, Screen Filter is the way to go.

Screen Filter. I've been using it for a when I read before I sleep. Very simple, good app.
Even if you do manage to find something to increase the max brightness, I wouldn't. There are usually caps on those things for a reason.

not a problem ... i experienced 'burn-out' SEVERAL years ago
seriously though, compared to my fruit phone, the maxx leaves a little to be desired in direct sunlight. it's ok, but just could be better. in fact, i almost switched back to my 4s because of that ... bought a mophie juice pack air yesterday and thought ... oh yeah, 2 days of battery, even more than my maxx. .. then i see that ICS is allegedly hitting in a few days so figured i would wait it out. i can always return the mophie!!!

1) you are talking of low light, cause if you raise it, white will become much more whiter...
2) white on sgs2 is not white, is blueish... simply some people recognizes blueish white whiter than yellowish, is just subjective... but no one of both has a perfect whiter... if you want real colors, you have to go on ips based screens, not amoled
For lowering brightness, I use this app called Easy on the Eyes. It can reduce your brightness from the original lowest setting. If you have a mac, you can find it on the app store.
I got my GS3 A few days ago and i noticed the screen look awfully warm, so i thought it was just samsung color calibration. But when i tilt the phone in any angle from a normal viewing angle the screen temperature goes warm to cold. Has anyone had a similar experience?
Same exact problem here man. I've posted a few threads about it but I figured I was alone since no one replied. My room step s3 is yellow as well. I'm on my 3rd and they have all been the same.
I'm just going to assume it's calibrated this way. Sure does look nice from an angle though lol
Sent from my SPH-L710 using xda app-developers app
upgrading from the gs II, I picked up my gsIII last week and noticed the warmer color...especially on a white background. The warm white reminds me of LCD instead of OLED... i was thinking Samsung duped us and swapped LCD for OLED.
Since the color becomes cooler when you change the viewing angle, i'm thinking it might be a tint in the screen glass or digitizer to give that warmer color when viewing straight on. Personally, I prefer whiter whites but it seems most smart phone users, especially iphone users, are used to/prefer a warmer white screen so maybe Sammy is trying to appeal to the masses used to a LCD look
I hate it, especially coming from the GS2. Looking at it from an angle the screen looks perfect, WHY SAMSUNG WHYYYYYYYYYY:crying:

I just did the same thing and the whites definitely look better than my laptop screen. I guess I can live with that.

Will using inverted apps save battery on the nexus 10? Or does it only work for amoled screens?

The LCD back light is always on using battery, no matter what color your displaying. With AMOLED, only the sections of the screen displaying color are on, and the black sections are portions of the screen that you could say are "turned off". AMOLED works by exciting a membrane with electrons, without using a back light.
To quote myself from the Nexus 4 forum:
"Simple answer: There is no affect on battery life. It will drain just as fast on white as it will on black.
Basic screen technology lesson incoming...
The image displayed on a regular LCD screen (aka most phones) will not affect your battery life. Only AMOLED screens (aka most Samsung phones) are affected by this phenomenon because the image is also the lightsource.
Battery life with LCD screens is affected by the backlight brightness. The backlight covers the whole back, is always white, and only shines through the LCD to allow you to see the image. Turn up the brightness, consume more power. Turn down the brightness, consume less power. Has nothing to do with the image on the screen.
Amoled screens do not shine through anything, the image they produce is also producing the light. That's why blacks use no power (off), and whites use max power (all on).
The end."

Hey, I just got a Nexus 5 and I'm fairly happy with it, except for two small defects: contrast and viewing angles. If you turn your phone even a few degrees, the colours will begin to wash out and go to white. I've attached a photo of the nexus 5 at almost 180 degrees, and I know that it's unusual to actually use it at the angle - but it's hard to show what happens without showing the extreme.
In the picture, the Nexus 5 has a black menu shown - notice how it's almost white.
I was wondering if anyone has encountered the same issue with their LG G2. It will help me decide which phone I'd rather have.
From what I've seen the LG2 does not have that issue. Great viewing angles! This is the reason I canceled my Nexus 5 order and purchased an LG2

I also don't have any issues with my ATT LG2.
NRGZ28, are you going to make a rom for this phone? I used to run your winMo roms way way back in the day.
It's an LCD display so it's unfair to expect AMOLED-like viewing angles.
But with that said, this is one epic screen. And this is coming from a guy who had the Xperia Z (not comparable with the G2's display, not by a long shot) and made the switch to this phone from the Galaxy S4 (better viewing angles and way lower color reproduction fidelity).
All in all, I am pretty satisfied so far. ?
I was playing Dead Trigger last night, and I was playing with the viewing angle on my G2 and I love it, full color deep blacks no white outs; for a lcd screen this phone rocks :good:
I have some blue color distortion when just tilting the phone a little bit, is my phone bad? Should I get a new one?

LCD viewing angles are poor compared to AMOLED. So I'm sure that you won't find it any different from the Nexus 5. Although, I found the HTC One more pleasant view but such a small screen.

From some angles mine turns a yellow tint pretty bad and a slight blue tint from other angles.
The G2 has much better viewing angles than Nexus 5. I've compared them side-by-side as a friend of mine owns the Nexus 5. G2 is the clear winner in that regard. I have never seen an phone LCD screen with better viewing angles than G2. It's no Amoled in that regard but it's not that far off.
Just get the G2 you gain more than what you lose with N5. G2 has: Better battery time, better camera, larger screen, fm radio, and software updates 4.4 and maybe even 5 but maybe by that time you will be considering buying a new phone. G2 all the way, never look back.

That is literally the only reason why I revile AMOLED at this point. Looking forward to taking a gander at my G2 screen when it comes in today. If I can resurrect my DNA, I can give a viewing comparison between the two as well.
If you want to feel better about viewing angles of the G2 or N5, go look at any newer Sony Xperia phones, then you will never worry about the viewing angles of any new phone ever again.
