A70's display treats dark pixels as if they were completely black, and turns them off instead of dimming them. Which leads to difficulty and inability to see dark things properly + distortion of the displayed thing (especially on the lock screen) because a lot of pixels are turned off.
The device has already been updated to the latest software version in Samsung's customer service center.

Test your device at night or in a place with dim lighting.

Yeah, that's how AMOLED works. And no, I can completely see properly dark things.

I know how AMOLED works, it's just that it's not working correctly. Check out the pics in the link, the screen changes the colors, and turns off way too many pixels.
You have more issues besides pixels turning off. Looks like posterization as well.
I don't have those issues with mine.

If you know how it works, then take your phone to the service centre as probably you have the warranty.

They told me there was nothing to worry about, so I guess that's that.
yes i have these problems too on the lock screen majorly i think its a step by the software to save battery. I had these problems on my old note 5 too.
Happens to me too.. Dark grey colour turn pinkish on lockscreen..

I was told that amoled displays have no problem (and doesn't take much energy) to show for example the time even when the phone is on stanbdy.
Would be pretty cool to have all black screen and just the time in white when the phone is on standby.
Is there something that does that already?

On my SGS2 I use to use an app called noled free from market. It used to display the time on my dimmed lock screen but only when I got a notification. You could download it and just see if the option is there to show the clock all the time. Hope this helps a bit
Yes it does but only on dimmed display, i want something to show it when the display is off. From what i understood amoled can light only certain pixels up. And that way show the time on turned off display using power just for the pixels it uses to show the time.

Cool, if you get it sorted would you mind sharing what you did? I would like that feature too.
Sure
........
Would appreciate some more input on that
Would love this....I am gonna go home and tinker with NoLED today...
You can do this with NoLEd.
Just go through the options.
Remember to enable NoLed from: settings/Accessibility
My only thing is it keeps the soft buttons on when it is displaying the time
works for me in 'test' mode, but outside that, no luck.
and yes in the test mode, soft keys are still shown ...

Doesn't the way noled keeps the screen dimmed kills your battery super fast?
Hi, anyone having this issue? I found out that my has a dead pixel that keep lighting up.
I have also experienced this, just above the WiFi indicator. However, I've only seen it with the charger plugged in for some reason.

Everyone line up to feed the troll. Someone needs to do something about spam such as this. Hint.
On topic: I have searched my screen by using a fully black and fully white image, no dead pixels on mine, though there have been a fair amount of complains on here about them.
I do have some backlight bleed on the bottom right of my screen, though.
I just noticed there's a yellow spot on the bottom left corner. .. It shows only over white/ very light background.
Is that the backlight bleed? (I suppose it's not)
It's probably...

It's probably some adhesive.
If the pixel is blinking and still lighting and its not dead, probably because its unstable or something. Go google playstore download Pixelfixer and keep pressing on the scren to change color rapidly. The pixel will be fixed. Mine was fixed. Try it. Rmb to click the thank me button!!

Hi, yes the pixel keep on lights up. had tried the software mentioned, but for me the dead pixel is somewhere around the 3 dots menu bar. The app doesn't allow me to switch orientation therefore i am unable to test it out. Anymore advise ?
Dead pixel...
First, losing follow apologize for my English. I have also discovered a dead pixel, but in my case, image is dark or black screen (with your cell phone on course). I applied programs if a pixel is vague, but nothing. I applied a little pressure on the screen, as is recommended in other forums and nothing.

That should be a light pixel, I'd sent my HOX for replacement due to a light pixel.
is there any way to keep screen ALWAYS ON in ambient mode ???
No, but why would you want to. It's on when you look at it.

Got the "interactive watchfaces" (LCA44B) update yesterday. Ever since then ambient screen is always on. Which really irritates me. I have to agree, no need to stay on if I'm not looking at it. Anyone with the same issue after the update?

Well explain. If Ambient Screen is on, but watch is ON EVERY time I look at it. A thing I don't understand tho, is that while it's a LCD display, it saves zero power by making half the screen black with digital clock on so many watchfaces.

I've played with ambient mode, and I can conclusively say that my watch face is not "on" EVERY time I look at it. Not even close. I work at a computer all day, if I glance down at my watch while it's in ambient mode, it isn't on. I drive, and I look at my wrist, and my watch is often NOT on. I understand that it turns on more easily and tries to anticipate hwen you're trying to look at your watch, but if you're casually glancing at the watch hoping it's on (rather than moving your wrist), it's often off. That's not ambient, it's just.... more sensitive.
As for your second question, only certain LCD technologies can leverage making "half the screen black" as a power-saving measure. Basically... most LCDs still use a single light source, so regardless of how much of the screen is black, the backlight is fully on. Some LCD technologies have the ability to turn on smaller backlights directly behind certain parts of the screen, so lighting only a small area of the screen is possible and saves a lot of power. I don't know enough about the technologies to know why, aside from cost, one would choose one over the other.

Go to android wear and settings/moto 360 and click on ambient screen on and tilt to wake screen to off. This will keep ambient on all the time. The only down side is that you will have to manually click the screen or the power button to go to full screen. I hope that helps

I already knew this but decided to give you a thanks since no one else has and you correctly answered the question along with how to activate it.
Hi Guys,
This is my first post so apologies in advance if this is not the correct place to ask this question or if I don't particularly explain the issue I'm having properly.
Something incredibly annoying and frustrating is happening with my display every night. I notice that around 7pm each evening, my phone will go from a nice crisp looking display to one with a yellowish/warm hue. It's as if my blue light filter is on but when I check, it's definitely off. I turn it on and nothing changes with the display, but when I turn it off, the display goes back to how it previously was. I am currently using the adaptive screen settings, auto brightness turned off, and blue light filter turned on with the customer schedule of midnight to 9am. I've also tried turning off blue light filter altogether but still run into this issue. It keeps happening every so often in the same night even after I've "corrected it" using the method of turning on and off the blue light filter.
Is this to be expected with the adaptive screen mode? I love how vivid and bright it is during the day, but despise the yellowish tint at night. Could it be possible that the blue light filter is somehow turning on by itself even when I've turned the feature completely off?
I appreciate any assistance. Samsung tech support was not particularly helpful and told me to go to Costco where I purchased it from and return it.
Thanks,
Cam
Have you tried configuring the color balance in the Display settings?

Thanks for your reply. I haven't tried that yet because I figured it didn't matter what setting I adjust it to as the display would automatically change in the evening anyways.

It's strange that even you already turned off Blue Light Filter, it's still making it dim. I find the dimming helpful since it doesn't strain the eyes at night. You could try reflashing the software for the phone.

I agree, but I would like for it to be turned on later such as 1 hour before I go to bed.
At 7pm PST this evening (about 15 min ago), the screen regained it's yellow tint again. I turned on the blue light filter, then turned it off to get it back to how it was initially previous to 7pm.
The Samsung support rep asked me to factory reset my phone, but that didn't work either. Would that be similar to flashing the software? I can certainly give it a try but was just wondering if the factory reset essentially did the same thing. I'm really not sure what this could be.

It's the custom schedule for the blue filter. You can change it in display settings.

This does not fix it. I have my custom schedule set to enable at 8:00 and disable at 8:01 but it still turns on at 7pm.
Finally figured it out!!! Go to Google Play Books. Open a book and tap the screen to find the letter A. From there go to settings and turn off the night light. Whew! This has been bothering me for months!! Hth!!
I'm having the exact same issue except I've turned off/on the blue light filter a million times and it doesn't fix it.
I also don't have google play books installed so it's not that. I've tried messing with every "display" setting but nothing fixes it.
My phone did this same thing a couple months ago and when I woke up the next morning, the display was back to normal. Now it just did it again but even though its a day later, my display is still all messed up (not as bright and crisp, has a yellowish hue to it).
Anyone got any other ideas or does this sound like some kind of hardware issue?
I had the same problem specially when I go to sleep at my dark bedroom, my phone is Samsung Note 8, and I just found the solution. Turn your phone to the otherside, look at the main Camera, mine has two cameras, a flash, and a rectangle black sensor at the end. I covered this sensor with a thick black paper that I found from a brochure, taped it in place, and Wala ? no more screen dim.
WOW

This has been bothering me for more than a year. I had to get a free book to try it out. Thank you SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO much!!!
I was watching a video on my PC's LCD screen, but I decided that I would continue it on my A70 instead.
I knew that I'd get different colors because it has an AMOLED display, but I didn't think that most of the dark areas in the video would get turned off! The screen literally turns off the dark colors even if they weren't totally black! And the more you dim the brightness of the screen, the more pixels it turns off! This can also be seen when you put a video lock screen that has dark colors and you dim the brightness. You're gonna see that most of the pixels turn off, and the colors of the remaining pixels will get distorted.
I've faced this issue on the A70, but on my brother's A50 the display is totally fine.
*Current lock screen wallpaper that I can clearly see this issue on: Decor (animated)
PS: My phone previously had the touch panel issue(where the screen feels sluggish when scrolling, and would sometimes click on stuff by itself), which didn't get fixed with the OTA update, which forced me to go Samsung's customer care, which they told me that they need to remove the firmware altogether(because the OTA update didn't install successfully), and then flash the already updated firmware, which indeed fixed the touch panel issue to a degree(it still happens but not as frequent as before).
Do you guys face this issue, or is it just my device? I also sent a message to Samsung explaining the issue through Samsung Members app, but they told me to go get the correct firmware flashed.
