Screen fading in and out at random??

Hey, I am new to this forum, but just go the EVO (first Android phone) and loving it maybe too much. I'm also working on a couple of games which I hope to share soon.
Anways, I got mine on the 4th since I pre-ordered it a couple weeks in advance from Best Buy. I have been lucky to not have any of the problems others have been having, but something I just noticed recently, and only in the Market, but this could be because it is a mainly white screen that you stay on for long periods while browing apps so it is easier to notice.
The screen seems to randomly fade slightly darker and then back to normal, but slowly. I don't mean the regular screen idle fade because I have mine set to 10 minutes. I will be scrolling, and then the screen will just fade slightly and then in like 5-10 seconds will go back to normal, and then fade again in a couple minutes.
Not a big deal as sometimes it's hard to notice, but just wondering if anyone else has noticed this and if there is anything that can be done about it.
Thanks!

It sounds like you have Auto Brightness turned on. In your setting, go to sound & display, click on Screen Brightness. Uncheck the "auto brightness" box.

I think that was it! The screen is also a little brighter too.
Sweet, thanx a lot!

I had the same problem, Thanks for the tip.

Now you can go back to that same area in settings and up the brightness manually if you'd like.

Screen fading in and out/Flickering
Hello fellow XDA'ers
I am experiencing a similar problem. My screen fades in and out and flickers.
I unchecked the Auto Brightness option. The screen did become a bit brighter. But this did not resolve the issue. The fading in and out and flickering continues.
If any of you fellow XDA'ers have experienced this and know of a solution, would you be so kind as to share your solution.
Thanks so much

[Q] Tne Homer Simpson Problem.

Hi everyone,
I just bought my galaxy note 2014 and i noticed this weird thing: the colors of my display seems problematic. This is most noticeable in the yellow color. If you watch an episode of The Simpsons, for exemple, the yellow of the charachters will be in a greenish, almost the colour u would expect from mud.
Some curiosities:
setting the brivhtness to max and disabling auto brightness seems to help A LOT. Not perfect, but much better, altought i dont wanna kill my batteries.
If you pull the notification bar, the colours seems magically fixed, but putting it back makes it go wrong again.
Maybe you can help me with that

Settings => Device => Display => Screen mode
Turn off "Adapt Display"
If that doesn't fix it, try manually changing the screen mode

Display Dimming/Tint Issue

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!!!

Screen too dim, backlight(Maybe) not working.

Hi all. I have a rather weird issue. After droping(oops) my phone, I ordered a new lcd. I shelved the phone as it was unusable until the screen arrived. When the screen arrived, I saw that the battery was dead. I charged it and changed the lcd. That's for the backstory. Fast forward to now. When I open the phone, the screen lights up at full brightness as one would expect at the android one logo. It stays there at full brightness for about 8secs But as soon as it starts loading android the screen dims to absolute dark. In the beginning I thought the phone was closing, you can't see anything... Unless you close the lights.
But even in absolutely dark room, the screen is still very dim, barely discernible. The phone works absolutely fine otherwise, touch camera sound etc. I backtracked the process and put it's original screen on, but it does the same.
I tried disabling auto brightness it does nothing. In fact, changing brightness from the slider does absolutely nothing whatsoever.
Tried calibrating the sensors from the engineering menu(not sure it was called that, the one you enter when you put numbers on the call menu) they seem to be working, but the brightness doesn't change.
Tried removing the battery for a prolonged amount of time (around 6 hours iirc). Still same.
At this point i'm thinking:
1)Software problem. I will really need to hard reset the whole thing, which i'd rather not, and hope for the best.
2)Bad screen, which doesn't explain why the previous one has the same problem, or why the screen works during the logo.
I hope I was able to give enough info. Any help would be greatly appreciated. Thanks!

Hi, I'm having almost the same issue (display very dim, but for me it is always very dim) and this manifested not after any dropping or screen replacement, I guess I just wrongly inputed a button sequence that configured the mobile in this weird status. It is really annoying as it is almost impossible to unlock sims, basically the phone is unusable, very frustrating....

Hey there, did anyone found a solution for this issue?

Has anyone solved this problem?

Have you found what was causing this?
I’ve the same issue, replaced the lcd on a xiaomi mi a1 and the backlight is present at the logo startup but completely black after that.[br]
On a dark room I can barely see the screen and all it’s working, but adaptive light button is missing, seems like the bootloader is able to use the backlight but not android itself

I have the exact same problem, i really hope someone knows a solution to this. I tried pretty much anything within my capabilities

Question Screen issue or software bug?

Hi!
I have received my Red Magic 8 Pro and immediately noticed something. The selfie camera is visible if the background behind it is simple. For example just a simple white or gray background. Depending on movie sometimes it also becomes visible under cartoons like Rick and Morty, however during normal movie I cant see it.
Is this normal for this phone?
Also, the software which handles the pixels in front of the camera sometimes can become bugged and a visible line is displayed. I can reproduce this issue by pulling down the notification bar and holding it at 1 spot.
Does everyone experience these issues ?

That's normal, especially if the screen is on 120Hz, and at low brightness. It's the so-called green tint issue.
