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.
Does anyone know of a way to adjust the display position? I recently noticed that I have a black edge along the top and right side of my screen about 1mm - 1.5mm thick. It looks as if the display has shifted down and left.
The touch sensors work correctly, pressing where expected. nothing seems to disappear off screen, except for one line of text in ROM Toolbox's menu.
Display density is at 240 default, R800i, stock SE ROM, 2.3.4.
Anyone else have this problem, or can suggest a fix?
Hey all! My Droid Incredible Two's softkeys are a bit messed up, and not in the way that they don't light up or anything. As you all probably know, the softkeys rotate when you rotate the phone, and for my search and back key, when the phone is upright, display both the vertical image of the softkey and the horizontal image (so basically both "versions" of the softkeys are displaying when my phone is upright/vertical), but when my phone is horizontal, everything is fine and theres only one "version" of the softkeys being displayed. So my question is, would getting a new digitizer solve my softkey display problem? Thanks!
when i say version i mean (the image of the softkey that displays when the phone is horizontal and the one that displays when the phone is vertical)
I just bought a refurbished Tab S and it looks like it hasn't even been used. It came with Android 5 and I didn't notice the problem, although I only used it for a few minutes before doing the OTA update to Android 6.0.1. Although everything seems to be working, if I grip the tablet between the lower right corner and the usb charging port, the screen blanks. Then when I remove my grip from this location the screen comes back on! I know ... weird behavior, right? It only happens in this area and it doesn't happen if I just press on the back or on the screen in this area. I have to actually grip on both sides. It's a beautiful tablet and I would hate to have to return it, so I'm trying to figure out if there is a way to fix it. (In everyday use it is just to annoying to aviod touching this area.) I read a post by vndnguyen (14-Jul-2015) on this forum that said:
---------------------------------
Our Galaxy Tab S has a Grip Sensor. You can check it by:
1) Use *#0*# to open Hardware Test, select GripSensor. You will see the grip sensor is located at the upper-right corner.
2) Use *#1106#. You can set the Grip sensor on/off.
-----------------------------------
So maybe I could fix the problem by turning the Grip sensor off. However I couldn't figure out how to enter these secret codes since a wifi only tablet doesn't have a dialer. I found an application called "Secret Codes" with an icon that looks like a lighted match. It listed a code with a #0 for hardware test. I pushed that button and it said it was invoking the code but then I saw no response from that.
Would selecting "Factory Data Reset" from the Backup and reset settings menu be worth a try to fix this problem? (Would I have to do the Marshmallow update again?).
By the way, here are some additional things I did to see if I could make the problem go away (to no avail):
- Starting the tablet in Safe mode
- Turning off automatic brightness, screen rotation, smart stay, screen timeout, Adaptive display, and screen tone auto adjust
- Turning off lock screen
- Turning off Palm swipe to capture
Any advice would be highly appreciated.

I have an issue with lock screen of google pixel 2 xl. My issue is, suppose my home screen image is while color and my lock screen color is black color. whenever I lock a phone. it does work properly but when I turn on the screen at that time my screen is showing some kind of flashing color of the home screen(white color) and after it turns to black color. So it is showing the tiny delay of real color in lock screen.!
I hope, it does not hardware issue.!
Does anybody face the same issue? Does anyone have a solution for this one?
