Black screen not totally black

Hey guys,
I thought the big advantage of the super amoled screen was that black is simply black because no pixel is lighting. But using the phone lying in the bed when its totally dark in the room reveals that the whole screen is not actually black at all. When using Noled, for example, the battery drain is pretty heavy since the whole display has a very low background brightness the whole time. Can anyone tell me the reason for that, please?

Likely to be an idle voltage causing a slight glow.
I don't think they can turn the pixels individually off, just dim them massively

Well technically you can turn them off. The problem is each pixel is controlled by a transistor and so the level to which you can turn each pixel off depends on that. It could very well be that the transistors aren't turning off 100% and some current is leaking through. It depends on the technology used and a lot of other factors. Nothing is perfect.

Black's look brown when brightness is low.

I was just wondering if anyone has a fix to this or anything, or if it's just an amoled problem. When I have the screen brightness turned down, all the blacks on my screen turn an ugly brown color. Is there anyway to make all blacks overall more black? Thanks

Mine look black. Just a dirty black. You sure you don't have the SLCD version of the device?

I just double checked to make sure, and it is in fact amoled. I guess what you're calling "dirty black" is what I'm talking about. Compared to my g2x lcd screen on low brightness, everything on the nexus is brown and the g2x is simply black. Its not that big of a deal but its one of those things that is annoying me lol. Is there anyway to modify this that you know of?

This doesn't sound right. My understanding of AMOLED is that blacks literally won't even light up (which is why dark backgrounds help save battery power). Each individual LED is individually lit up. If there isn't any color on the screen, it won't light up. My blacks always seem black, no matter what the brightness of the screen is.

For example, look at the status bar (gingerbread) while you change the brightness, for me as the brightness goes down, the black starts to have a slight brown color to it. Or is my screen just screwed up? Lol its not like its major, its just annoying compared to g2x

I don't notice that at all on mine. It stays as black as it was when on full brightness. Does it still happen when all the lights are off in the room?

It happens when I'm in pitch black darkness, if there's light it isn't as noticeable but its still there

Screen Brightness manipulation?

Is there any way with an app like AnyCut or SQLITE to edit a field to make the screen brighter? I know this may be a longshot, but with some of the other parts of the phone being capable of manipulation, I thought I'd at least ask. I understand the drain on the battery and possible other risks, but the screen, even at 100% brightness, seems to just not be that bright..

What? I can see my screen in bright clear skies daylight.... that's a bright screen! You live on Mercury or what?

If I stand outside with my screen set to 100% and auto turned off.. I have a hard time plaing contract killer because some of the characters become extremly hard to see.. If I play it on the galaxy tab in the same conditions, the characters are easy to see.. But it is true of most things I look at on the screen.. Out and about in direct daylight, the screen just isnt as bright as it needs to be..

That has nothing to do with screen brightness. The galaxy tab is a Super Amoled screen and the Thrill is LCD. That is why Samsung phones are more visible in direct sunlight too.

moved thread to general-Q&A section

I wish mine would go dimmer. I like to keep it on auto and its usually pretty good but at night it keeps my screen way too bright. If I use the built in widget to toggle the brightness it just puts it too dim. The only way to get it to a decent dimness in the dark is to use the slider. I say the screen it too bright 90% of the time.

Now that is do-able. I'm not sure how to do it though. Cm7 has the option to adjust the auto-brightness levels based on specific light sensor values.

[Q]Auto Brightness problem

Is anyone having issue for the auto brightness?
The screen brightness adjust automatically, but is too dim in a dark environment.
Wanna know if anyone have this issue? Or my Z3+ have problem with the sensor.

Does it get bright enough under direct sunlight? If so, the sensor is probably good. Now in my case, it does get quite dim in a completely dark room. It's a good thing. I wish it could get dimmer!
You could also run a service test on the 'ambient light sensor' by dialing #*#*SERVICE*#*#. In a fully dark room, mine reads 0 as it should.

Yes. Bright enough under direct sunlight, and 'ambient light sensor' also reads 0 in a dark room now (not fully dark, with PC monitor screen on).
I think mine is too sensitive at the dark environment. I was on the street around sunset yesterday, and the screen go very dim.
I will test the 'ambient light sensor' tomorrow around sunset time again.

Did you remove the screen plastic. Sounds silly but I didn't for a few days. I didn't realize it was there and i can now reduce my brightness level a lot which will also help with battery.
There are 2 covers one you remove and one that stays, I think

That's good to know. I thought the second one (factory screen protector) might come off with the Sony logo like it did on Xperia Z
http://www.xperiablog.net/2013/03/2...-the-xperia-z-screen-protector-sony-logo-too/
Btw, did you try to slide up the 'Brightness Level' under display setting even though the 'Adaptive brightness' is on? It should set the minimum brightness level higher. It's more like semi-auto brightness on the recent Android version. So try it out when it feels dim to you next time in order to find a suitable 'brightness level'

Do you know if the original screen protector is also shatterproof? or is it just some cheap crappy one?

It does not bright enough under direct sun.

Seems it is a cheap crappy one.
BTW FYR I only removed the upper one.

The upper one with texture should be removed the second might as well be left in place until it gets scratched, its pretty okay and does the work. As for the back I taped on the texture one until I get a back protector. Kinda silly to not include one from Sony's side

Outdoor visibility (max brightness)

Rate this thread to express how well you can see the HTC 10's display outdoors. In case you've been playing Minecraft for 18 months straight, you might not known how to get outside anymore. Well, find the door and walk through it. A higher rating indicates that it has very high maximum brightness and thus fantastic outdoor visibility in direct sunlight.
Then, drop a comment if you have anything to add!

Perfectly fine in 12258 lux of sunlight.

Seems reasonable, not as bright as an S7 but it's not an AMOLED.

The screen is most definitely very very bright in bright sunlight on "auto" setting with slider to the max. I have no issues with the brightness outdoors. Make sure to keep the "auto" setting, there is a brightness boost built in with "auto". Also, do not use Power Saver feature (I am not taking about the Extreme Power Saver mode). The Power Saver will ruin the brightness in sunlight completely and thoroughly.

Compared the 10 with my Samsung S6 at noon in direct sunlight in Tucson, AZ on June 06. Couldn't see either for ****e.

Oh, so that's why it looks so strange in direct sun light It's not looking nice with the boost, but it's very effective and helps a lot

Mine auto brightness is also huge step back comparing to previous One's. It is too bright in the evening or at night if my slider in auto mode is at about 75%.

Use Lux Lite (can do the same)

Personally, I think max brightness on this phone isn't nearly bright enough. When I stop off at the Starbucks drive through in the morning and attempt to pay with my phone (pops a barcode on screen for the barista to scan) they always need to take my phone from me inside where it's a bit darker to scan. I have never had this issue with any other device, and never see any of the cars ahead of me having a similar issue. This is with auto brightness on and the slider all the way at max.

Remember that when you go outside, the sun is bright, you slip on your polarized sun glasses. Next time you look at the screen, it's dark.
Remember the screen is polarized as well, and not in the best orientation. Turn the phone horizontal, see if brighter again.

Slightly lower than on S7 but visible enough.

Yeah, I can relate. From all the recent phones I've tested, the 10 fares the worst in direct sunlight / bright day environment... Even so, the only time I find it really annoying is when I try to take photos or shoot video. I always feel that the screen is too dark or that the photos I take are too dark. When I look at them back home, on a large PC screen, I see that the photos are ok, well-lit...

Yeah the polarization was a completely gooned up oversight in manufacture of the lcd. Could have done it 90 Deg off.

Then you can't take pictures with sunglasses on and you can't use the gps while driving with the SGs on. It goes both ways in terms of preferable polarization orientation.

Much brighter than my LG G3. I don't need to crank the brightness to 40% indoors anymore. I can keep my HTC 10 around 15-20% brightness and see it just fine indoors.

Compared to the Nexus 6P the HTC display is visible with no issues on direct sunlight. It is definitely not perfect, but I really like it.
