Guys how are you doing? I'm having a strange issue with my phone, i've searched the forum about it but couldn't find anything about it other than a couple of messages without any conclusion. This problem is mostly noticeable when having the screen in minimum brightness, it's like the backlight flickers a bit. If writing an SMS for example, whenever you press a keyboard key the screen flickers (it's very faint but noticeable). Also, when you open any app, it's like the brightness goes up a bit and down again, it's a very strange issue. Is anyone having this problem? Seems to be a software glitch because if you leave the phone in a static screen, that doesn't happen. It's updated to the latest fw version btw, it always happened.
To make it clear (and if anyone wants to try it), this happens with auto brightness, and the slider set to the minimum in a dark condition, whenever the brightness is medium/high at least i can't notice it.

I notice this in opera, and today in the facebook app too, and was really baffled. The effect is quite subtle, but repeatable. When moving my finger around the screen, eg on the bbc news website panning to the top left, my screen dims. It stays dim when I remove my finger, and brightens again when I pan back down to the right.
Weird, huh?
So far it's just a curiosity and not an annoyance. Has anyone else seen this?
So I am not the only one who noticed this. I sometimes find this behaviour a bit annoying, especially in low light.
The phone has an ambient light sensor. It is adjusting because you are causing a shadow over it.
You can probably turn it off
Under the power settings/backlight - auto adjust backlight. Just uncheck it.
Any idea where the sensor is located?
Do you really think it is the ambient/light sensor? I sure don't. Scrolling through different websites I can easily reproduce this:
You scroll from one point to another, this just has to be a couple of pixels, and the screen adjusts the brightness. That is within a room with a fixed source of light and I am keeping my body as constant as possible to avoid the shadowing.
Scrolling from point A to point B makes the backlight adjust itself, even without casting any shadows or similar. Scrolling back from B to A makes the backlight instantly adjust itself back.
It's your finger causing the shadow, not your body. If you introduce an object into an ambient light source, you will find that said object will reduce the ambient light by a percentage due to partial or total obstruction. The light sensor is detecting this percentage and adjusting the screen accordingly.
The sensor itself is somewhere near the speaker.
I'm pretty sure this doen't have anything to do with the light sensor UNLESS it's cause by the screen itself becoming brighter and this registering on the light sensor, eg internal light leak.
My best guess is that it's connected to the presence/absence of certain colours on the screen, and is related to the video driver. Next time I get it I'll see if I can reproduce when scrolling via the kbd, to eliminate the theories about casting shadows on the screen.
This is not FINGER SHADOW!!!
You can notice this same thing when you plaing Solitare cards and using Stylus.
I'm sure i did't do any shadows and anyway when i pick up any card and moving aroud screen u can notice screen brighting up and down.
Using Opera 9.5, on this site http://game-board.blogspot.com/2008/05/alternative-monopoly-rules-and-game.html zoom in with double-click, scroll about half way down to the paragraph beginning "property has too much pollution on it", then scroll up and down and notice the change in screen brightness. please post if you can repeat. it does not work with the keyboard.
btw, does anyone know monopoly "bloodbath" alternative rules?
I've noticed my screen doing this without causing any shadows & without even touching the screen at all, like a 'breathing effect' when it is completely idle. I think it has something to do with light sensor polling interval which is editable via the registry, advance config and HD tweak...but since I flashed NRGZ ROM (21/08/09 build) this issue has gone anyway.
There is this weird bug I'm encountering every once in a while, like once in 20 days or something. And there is no way to reproduce it forcefully, as it happens randomly in different situations, with no defined pattern at all.
So here it is. From time to time, something is causing buttons backlight to be as double as bright compared to normal state. And I'm not exaggerating when I say doubled brightness, it really is. Like ultra intense light.
And the only way I discovered so far, to back it to normal state, is to restart my phone. Did anyone else encounter this bug? What is causing it?
So, I notice that when I get int apps, and go to the home screen, the screen gets brighter, meaning the apps are dimming the screen ever so slightly, any fix? I've noticed it the most in Chrome, but it happens in many apps.
Yes, that's been noticed by many of us, with varying levels of irritation. I believe that if your brightness is set to "Auto", you won't see the dimming, but I'm not crazy about how the Auto mode works. I should confess that until someone else called attention to it, I never noticed the slight dimming myself, so I won't get too puffed up with outrage.

I have also noticed this. The screen suddenly gets dim while using some apps (mostly Chrome). When I press the home button, the screen brightenes up to its set brightness. Also, I have auto brightness turned off. So, this shouldn't be happening. Currently the only fix is to exit to the home screen.
Hello!
Can you guys test the auto-brightness in dark environments?
My screen flickers shortly before the auto-brightness function find the best brightness.
Unfortunately, I can´t make a video, because this is the only phone I have.
The screen don´t flicker everytime, only when the auto-brightness go under 20% and stops shortly before.
Is it a hardware issue, the new update or the software total. I have the S9+ since yesterday.
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
