Solution to LED notifications

While browsing this, I discovered a possible solution to replace LED notifications. I believe a little more than 9 pixels would be fine however, maybe it pongs around the screen like a screensaver.
The good thing about AMOLED screens is that when a pixels display a true black color (#000000) it's actually completely turned off that pixel, in fact displaying true 480x800 black image on the SGS screen resemble turning the screen off. so i was thinking what if the screen was completely black except for few pixels in the coroner that are green to indicate miss calls, the screen will only consume power to keep these few pixels on, the rest of pixels will not consume any power.
To demo this, i made this 480x800 image with all pixels black except for 9 green pixels on the top left corner, you can save it and try it in your SGS full screen, as for the power consumption, the screen have a total of 480x800=384000 pixels, of which only 9 is on, so 9/384000=0.002% of the screen power only consumed to keep these 9 pixels on.

brilliant! thats so smart, how do you set this to show up tho? is there a setting for this? or would it require mods?

Sounds great but I guess it'll require mods.
But he's wrong when saying "black is like display off" since there's still the backlight which uses battery
Edit // or am I wrong? http://forum.xda-developers.com/showthread.php?t=706640

I think u r wrong. .. I remember. Reading that old have no backlight. That is why they save power over conventional displays.

AMOLED doesn't have a back light.
It has True blacks. I.E. when displaying the black color, it just doesn't turn on.
LCD's, to be visible, need a backlight/sidelight.

Yea but in that case would'nt it need a back light to illuminate the 9 bright pixels??

OLED displays are made up of tiny organic LEDs (light-emitting diodes), so each subpixel emits its own light - the display is black when they're off. Different amounts of light emitted from the different colour subpixels gives a pixel with an overall colour. So if only 9 pixels are lit, only those 9 pixels are consuming power. This also means that brighter and whiter images use more power.
This is in contrast to a LCD, where there's a backlight that makes the entire display white when all the subpixels are off. Liquid crystal subpixels block the light to varying degrees in order to produce the image; each subpixel has a red, green or blue filter to produce colour. Therefore the image is subtractive from a white background. The power consumption doesn't really vary depending on the image being displayed, because the backlight is always on over the whole screen.
However, I don't know if the CPU would be able to sleep with the display "on", even if the display itself isn't consuming much power.

Nope. Only the nine pixels will be switched on. No backlight involved.

Hmmmm good point. Maybe in slo-mo power saving mode ;p

I prefer if the menu and back buttons would flash

Well, lets see if it does. Besides a few circuits keeping the screen ready, I don't think the display will use much power. To test we can try this and note the battery change with this on and find the delta battery percentage over time ratio and again with the screen off. I think the CPU will go idle if the display is not doing anything.

Me too, but this is just another way if that fails. I don't know if anyone has tried to do this yet.

Red LED appears

A friend who just got an EVO a few weeks ago suddenly has a red LED lit continuously when the phone is on. Everything seems to be working correctly. The LED does occasionally blink off, but is on most of the time. Tried rebooting and changing a few settings. His EVO is completely stock, no root (yet).
Anyone know what this is about?

Couldn't honestly say. Probably its a bug in the stock Rom. Once he root and flash a custom Rom , it may go away

if its on the right side of the earpiece speaker then thats the 4G notification led
let me know what side

When looking at the front of the phone, it's on the left side of the earpiece. It's the same (or very close to) the green/amber Power LED.

I was looking at my friend's EVO again tonight- I noticed that the red LED that's appearing is right below the green/amber POWER LED. It's hard to see the actual colors, but I took the picture to show location. The LED on top is amber [charging]. The one immediately below it goes off when the screen is off, but is otherwise on all the time.
Has anyone ever seen this before?

Know about Honor 5X - LED Indicator primary functions

Do you know how I am communicating with my phone directly with its amazing features.
I usually don’t always carry cell phones in my hands all the time but my phone is very smart and it will notify me for messages, missed calls etc.
Just you need to enable your LED service indicator
Step 1: Go to Settings.

Second screen auto brightness

I just got a replacement V20 from T-Mobile because my old one was having huge noise reduction problems with the camera. The replacement has a lot less noise reduction, but it also has another problem.
The second screen on my old phone, when it's acting as an AOD, will properly adjust to ambient brightness (and even follow the brightness adjustments from Lux). The new phone, however, will keep the AOD at the same brightness level as when it was on, but only for a few seconds. After that, it goes to full brightness. If I put my hand about an inch over the light sensor (so I don't turn off the AOD), it'll go dim. It seems to have only two levels: 0% and 100%. It doesn't go anywhere in between.
Using Lux, system auto, manual brightness, whatever, has no effect: the second screen still will go full bright or full dark, depending on how bright the room is. Has anyone else experienced this? Is there maybe a fix? It's driving me crazy.

Yep. My LG V20 second screen adjst the brightness too. In dark place , the brightness go down.

I don't think you understood. The issue isn't that it adjusts; I'd expect it to do that. The issue is that it's only ever off, at 0% brightness or at 100% brightness.

You say that you're using Lux, but what sounds like an issue to me is that you also say that you've tried the stock auto brightness and the screen still doesn't work right. Mine (ATT version) works with both stock auto and with Lux.
I'm wondering if something is wrong with the phone?
Try these settings in Lux though. Mine is working with Lux, so maybe duplicating my settings will at least be a start.

Otherwise, something else is going on like maybe another app is somehow interfering or (worse case) the sensor on the phone is broken.
EDIT
Oh and the second screen brightness with Lux and the system's auto brightness both depend on the actual screen brightness settings for that light level. So in Lux, if your bedroom light brings the main screen to 50% brightness, then when the main screen is off, the second screen will set to 50% as well.
I also forgot to mention that Lux is set to. Adjust Dynamicaly and using the Smart profile (this is in the notification drawer pull down)

Thank you for the help, but it's just barely too late. The phone decided that it was going to behave all of a sudden, with no action from me.

May I know how to get into lux settings?

Blue tint on the edge on s10+ is it normal or faulthy device?

I can only see it on white background normally when i hold the device and is more noticible when slide the phone:

Same here

I can notice it always on white or very light background while i normally hold it its barely visible but as i slide om one side it dissapiers and it shows more on the other side can anyone tell me is this normal or defect..

I also noticed a pink hue with white background if screen is tilted more than
30 degrees...

Normal. Been this way since S8/N8. You won't notice the effect with dark themes.

Could it be the pre-installed screen protector?

Modern AMOLEDs will shift colours when not at optimal angles, they're intended to be used perfectly parallel to your view, that's perfectly normal and won't be fixed until MicroLED becomes real on mobile.
Besides that, I suggest you to enable vivid mode and choose a white temperature of your taste, you'll find the ideal white being closer to the blue end, but that works directly against the embedded blue-light filter of this generation and can disturb your health.

Seems normal...

Just 1 reason why the curves are useless and annoying

This is normal. I remember on my S8 there was an option to adjust the hue/color of the screen edge areas... I cannot seem to find it on my S10+ though.

I thought all of this was normal as well until I did an exchange. I had the purple/pink shift at even the slightest angle and the discolored edges. I exchanged my phone for a later production date model and my screen is as perfectly balanced as it gets. I highly suggest an exchange if you can notice the shift

I have tested all phones at our restores and they also shifted a bit to a tint of grey-green color. Wouldn't say blue, but sometimes can our eyes see it as that. However, purple/pink tint as it happened to you its completely different than what the guy here asked for. And if it occurs, then yes. Change your phone. Otherwise it's all normal. I've been tested like 11 phones and every one of them including mine has that.
Skickat från min SM-G975F via Tapatalk

its the angle at which the edge falls down to. its like a prism instead of white light your getting the next color on the color wheel white blue cyan green yellow orange and red. if you look at the edge without looking at the phone straight down you see the change from blue to white as you move the phone to the edges

SO long as it's not green you're good to go.
