Just noticed the LED notification light on my wife's XZ1C is a bit off center.
It's noticeable when charging. It's supposed to be red light but I can also see small green light as well.
Anyone having the same issue?
Same here.
When it's charging is half red half green
It's a surface-mount Red-Green-Blue (RGB) LED.
All RGB LEDs are actually three separate LED chips stuffed into a single, surface-mount package. Each of those single-color chips (called a "die") is separate and the physical distance between each color depends on the manufacturer and model of any given LED package.
Essentially, in order to show a color that isn't pure red, green or blue, you have to light up more than one LED. If there is a large separation between each die, or you are close to the LED, then you will be able to see each color separately. If the distance between dies is smaller, or you are further away, you see the color that is formed from the mixing of those single die colors.
A decent example of that is here:

}
Another way to deal with the "separate colors" issue is to use a heavily frosted cover on top of the LED package. That can work, but also significantly reduces the brightness of the LED, which means you have to use more power to light it. Using more power can then make the individual colors stand out more, requiring more frosting, etc. So there's a limit to what you can do there.
Using closer spacing means you end up with smaller LED chips, which have less area to dissipate heat, which means you have to use less power, which means they aren't as bright.
So it all comes down to a bunch of trade-offs.
TLDR: Step back from the phone a bit and what you'll see is orange: Red = 255 / Green = 128 / Blue = 0

thank you for all this explanation! love to know it! I always like to know how works stuff. :good: actually this LED doesn't bother me, even in distance I can see the line which both become different colors, but it's not a problem. The real problem for me is to see this light everytime that I've charged this phone. Why can't I just turn it off?

I have the brightness set to zero, but I still find the screen too bright especially at night when the lights are off. Even at the lowest setting, the browser will light up the entire room and its very hard on the eyes. Is there a way to lower the brightness even further? Is there a hack available that will do this?

But then you can't see anything, that's almost as mental a suggestion as layering up 3 or 4 mirror screen protectors.
Instead of suggesting **** you could try to answer his question in a real way.
I think there is a way via setprop..
Try this in terminal (after su)
setprop settings.display.brightness 0
Sunsglasses sounds like a good idea.

Thanks for chiming in with an actual suggestion. I tried changing the setprop setting to 0, but it didn't decrease my brightness any further than what I can achieve in the Settings menu. It's too bad, I wonder if an app could be made to force the phone's brightness to decrease even further.
You know what... I like this suggestion. I am one of the few people that sometimes uses the phone as an alarm clock and have it sitting next to my bed. I work nights but get off work at 5 in the morning. When I get home I sleep. It's nice to wake up and look at my phone without having to reach over and hit a tiny ass button just to check the time but keeping it on means that I have a night light shining while I'm trying to sleep. So I like this idea and would like to see it dimmed by at least another 50%.

I agree. I often grab my phone in the middle of the night to view new emails or google search random thoughts. My eyes get scorched though even when the brightness is turned all the way down.
I like the sunglasses idea!
how about putting on a darkened screen protector?

Do you have a link to one?
Me too.
I do alot of surfing in the middle of the night with the wife and baby in the bed and its pretty dam bright even when set to 0.
I run the brightness widget (not sure wich one) and I also use Timerific to auto dim to 0 after like 11m.
Sometimes I will see that the brightness is set to -8. Even though it doesnt seem any dimmer than normal, its jsut an observation.
I think that If we want to go dimmer its gonna take some sort of kernel hack.
I tried setting it with a - value and it didnt work, although none of the other set prop stuff worked either I think the apps i have set are blocking it somehow.
Ill mess around with a fresh rom and see if it will go into negative.
I also noticed that sometimes when its auto setting thebrightness levels it will go below what looks like 0 brightness for about a half second before it sets to 0 so I know its physically possible for the screen to go at least a little dimmer.
i know there was a way of getting it to -13 % by playing around with the settings on the brightness widget and useful switers..
I've gone through a few BT keyboards with Android tablets over the last couple of years, and I think I've found the perfect one for the N7:
Perixx PERIBOARD-805, $30 at Amazon
It folds to about 6x3.5" and about 1/2" thick, just a little smaller than the N7's active screen area and about as thick as my landscape stand case when folded. When unfolded, it's kind of small compared to a fullsize or even a standard laptop keyboard, but is still easy to touch type on. The split down the middle is a little awkward at first since some of the keys down the middle have been stretched to fill the gap, but not a problem after a few minutes. It's a full laptop style layout similar to the Apple tenkeyless keyboards, with F1-F10, two sets of CTRL and ALT, ~, ESC, and \ in the right places. The arrow buttons are wedged between "/" and right Shift which looks funny but hasn't been a problem. The FN button also activates a bunch of Android and iOS specific keys, like media/volume controls, lock, wake, home, and search.
Everything seems to work as expected in a terminal (AirTerm and ConnectBot) except I can't get the PGUP/PGDN to work in the terminal (FN-arrow up and down), though they work fine in Google Drive. Not the end of the world, and probably something that editing the keymap can fix.
Keys have decent travel (1.35mm I measured) with a sharp tact for something so cheap, and use a scissor mechanism so they don't wobble much at all. The caps aren't curved, which is the trend for chiclet keyboards. It flexes a tiny bit if you pound on it, but much less than many laptops I've used.
It has two buttons on the inside right: one to power on/off, and one for pairing. You hold the power button for 3 seconds to power it on, then the battery and BT LEDs blink a few times to let you know it's alive. Turning it off is done by holding it for a second or two, but there's no indication that it turned off other than the dropped connection on the N7. I'm not sure if there's an auto power off or how long the battery should last as the manual kind of sucks and I've only had it for a day. It does not turn off when you close it, but if it's like most BT keyboards I've used it sips power until you are actively using it so it might not matter.
It's powered by an internal Li-Ion pack, and charges with micro USB. Not sure on battery life yet, but it's nice to know I don't need to carry an extra charger or AAAs. It ships with a short USB-A to micro USB cable that most of us probably will never open, but a nice touch anyway. It can be charged with the case open or closed, and the charging point is right near the ESC key so that it faces away if you want to charge it while using it.
Unfolded, the case rests on 8 feet: the four surrounding the hinge are bumps in the plastic, and the ones at the corners are rubber to prevent slipping on a desk. When folded, the case has a glossy hex pattern on top of black matte plastic, which is a nice change from plain black gadgets while not being too flashy. It feels sturdy enough to take some abuse at the bottom of a backpack.
Anyway, if none of the other keyboard options are doing it for you, and you want something very portable, get one of these.

It's unnoticeable. In the few BT keyboards I've used this has never been a problem. I wouldn't use it for serious gaming, but if you're of that bent you're not using anything wireless anyway.
Sometimes it takes a few seconds for the keyboard to wake up and connect if it's been idle for a while (usually minutes to hours).
I've noticed these lines appear on screen when my finger touches it. Horizontal lines appear, they seem to actually be in a fixed location, fading away after a second of no contact and then reappearing in the same location.
I have tried:
Restarting
Booting into safe mode
Remove screen protector
Changed screen brightness
Went into developer mode, there was a setting there to show where you press and it was turned off already.
Anyone know what on earth it is?

This must be a hardware problem. If you're still under Huaweis warranty, send the phone in for repair.
Hint: print the photos you made and put them directly beside the phone, so the repairman can see the problem.
I had the exact same problem and they disappeared after a couple days.
I noticed that this lines appears after I activate "glove mode", but when I disable it, reduces the lines. Only stops this "bug" after a restart. Verify if you have glove mode on (settings > smart assistance > glove mode)
I got this problem too. Very rare and I think it's a hardware thing.
A colleague of mine made the screen do this when touching it but if I did the same nothing happened. The effect (he had) on the screen went away after a few tries.
I blame it on static electricity but might be something else...
I have a similar problem except I have 3 faint white vertical lines running down through my screen, barely noticeable though, so im not sure what the problem is
?
Anyone have further information? Im worried sick because I got this problem a couple hours after puting a "smart case" (cheap knockoff) on the device (has a magnet on the back and on the side) and a "glass" protector. I'll remove these for now and see what happens.
UPDATE: I'm almost certain it had something to do with my cheap screen protector (I haven't removed it tho). In any case, it took about two weeks before these lines seemed to stop appearing. Haven't seen them for 2 or 3 weeks now.
Electrostatics

White stripes (or lines) on the IPS displays appear as a result of electrostatic voltage. This problem has been confirmed for a number of smartphones other manufacturers: Huawei P10 Pro, Sony Xperia XZ1 and XZ2, HTC U11 and U11+.
for example, Sony says:
Sony Mobile is committed to providing the highest standard of product quality and customer service for all of our products. Due to the characteristic of the display, you may see stripe patterns as a result of electrostatic in some models. This is not a functional defect and usually the stripe patterns fade away as the electrostatic disappears.

"Electrostatic voltage is still just voltage. Materials that can store electrostatic charges are insulators (or are insulated by something), so the charge cannot leak away."
IMAO, this problem is not a global one, but it seems to me that it is related to hardware defects in the assembly of smartphones.
I've seen a youtube video where author says that dark mode in S9+ killed his phone screen.
He said that when you use app that is not affected by dark mode (stays white) and this app uses keyboard (black in dark mode) it causes screen fatigue when you open keyboard and than close it.
Of course it depends on usage but in his example (using this app few times a day) his screen died after two weeks or something like that.
Is it even possible?
If I understood him correctly it wasn't usual screen burn in.

It seemed WEIRD but I decided to ask. I've thought abut it like a light switch.
On bright screen when we turn on black keyboard it will make pixels black. Maybe doing this a lot could be harmful.
Well... I like dark mode so I might turn it on again someday

On Oled screens, the sections of the screen that are black are actually turned off completely. So so those pixels aren't even being powered.
I think that idea behind "problem" is :
When you have bright screen and you turn on keyboard with black elements than turn keyboard off it will work like power switch.
To be honest I choose to believe people from xda and assume that if I'm not unlucky than my screen is gonna be fine .
I feel that dark mode has got to much bright elements like icons . They should be grey or something

Imagine Light bulb.
When switch is on there is light. When off there is no light.
If I'm correct light bulbs burn when you turn on power . Not while emitting light.
I have no idea if this comparison is even near the truth but this is what came to my mind .

sounds logical to me.
let's see if an engineer can disprove it.
im not one but i know that incandescent bulbs and oled are pretty different. the burning filament part of a bulb has a high peak uppon power on and and just the nature of the "burning" makes it much more prown to burnouts. plus the AC current switching created by 50 or 60 hz must be a big part of why bulbs break more...just the strain of it switching polarity back and forth and there is no capacitor to smooth it out. Oled being part of a DC electronic device and natively consuming much less, has all sorts of controls and capacitors to smooth everything out and moreover, it is constant.. but id bet if there is some sort of app that could strobe between full max brightness and blackout real quickly, I'd presume failure faster than we might think.
LED works differently than light bulbs... if LED is near to dead... it won't produce the correct light colors which is nearly happens when there's a screen burn on any OLED screens... it will display colors differently
Correct me if I am wrong but that's how I see it

Maybe some conclusion ??
Dark mode and normal mode are the same for the screen ?
Oleds are designed to turn off the pixels that are not neded, so no, using a dark theme wont damage the screen.
and the power switch theory is very far from beeng anything, everything you turn on works like a "power switch" and you dont see everything on fire
in the case of the phone, is best for the pixels to be off because they have a sort of fixed lifetime, you will extend that lifetime using them only when needed.
A friend of mine used their S8+ in light mode at 80% brightness and after 18 months the screen was badly burned in. There was a brown haze affect over the entire screen and the status and Navigation bars were heavily noticeable on videos.
Dark mode saves battery and is easier on the eyes. Samsung has done well at preventing burn in, whereas LG is still questionable.
LEDs are diodes. A diode is a pn junction (a one-way valve), which is also what you find in transistors. These things are designed to switch on and off thousands of times a second, and do so for years with zero issues. LED brightness can also be driven with pulse width modulation, switching hundreds of times a second, with a modulated duty cycle that varies the LED brightness. Also note that while you are watching a video on your phone, five million LEDs are getting their brightness modulated 30 times a second. These things are designed exactly for this stuff. Nobody on YouTube will convince me these OLED screens are damaged by normal use.
NORMAL USE.
That said, these screens get VERY bright, to accommodate infrequent use under full sunlight. But some people complain that they can't stand (or even read from) their phone if the brightness is any less than full blast. My wife has it this way even in a dark room, or worse, while DRIVING at night. It's ridiculous! Auto-brightness is the way to go. My Auto-brightness varies from about 10-50% in normal indoor lighting, and it's very comfortable on my eyes while saving battery. I've just finished my normal 16 hour, day and I'm have 79% charge left (seriously). I last took my phone off the charger 16 hours ago.
Download and run the OLED tools app to see how bright your Note9 can go. You have an enormous amount of brightness headroom that you should never need to use for very long.
Dark mode actually helps prolong the life of AMOLED/OLED displays. As pixels which display black are turned off, so only the pixels which display color on the display are active.

Is it your problem like this? I've noticed it always in the right top corner, specially with the blue light filter on.
The interesting part is that if I get the brightness any higher it disappears.

Well it's not a faulty pixel, the screen is not damaged or anything. You can try to use your warranty but in my country warranties don't work for such negligible and insignificant issues. Heck, in my country you try to use the warranty for a minor issue and Samsung service refuses the repair saying your phone was "pickled" with water while it never was.
I'm gonna keep it that way.
i dont think samsung uses dc dimming, so on a pwm screen it shouldn't have that kind of distortion. Sounds like a screen issue.
All A71 and S10 lite appear to have this defect. I already changed mine twice and both have the defect. I've seen cases where the device has been changed 3 times, and came with this defect every time. But it is a difficult problem to detect, so many people claim that their devices do not have this defect. The problem is usually only visible in some shades of dark gray, such as the image shown below. To check it is necessary to decrease the brightness to between 5% and 10%, go to a dark room and put this gray image in full screen.
My screen is just same as yours
