Spots on screen - Xiaomi Poco F1 Questions & Answers

Today I was inspecting the screen of my POCO f1 for scratches. I was searching by using my other phone's flashlight. Fortunately there were no scratches but I saw some spots on my screen. Under the light of the flashlight they appeared green in color. The screen was off the whole time. With normal use I was not able to see spots. But when I throw bright light on screen they are visible. Can someone please check that and help me to know what are that spots and why are they on my screen. Thank you

[Q] the dark spots?

i bought the i9100 few days ago.when i am in the"dark"room(no lights on), and i view a pure black picture, i would find dozens of dirty dark spots on the screen!! however,just a little light on the screen ,these spots would be unvisable or hard to see. anyone could have these problem? or help to give some explaination?thanks
Oops, what is that? Try to take a Photo of it, without a photo it's impossible to detect the issue. Also do a Screenshot and post it here.
Regards.
honestly, can,t take this photo ,cause,even a little light on,it become unvisible.But,just put a pure black picture on the screen,and sit in a "full dark" room, better at night,watch carefully the screen, maybe found them.try it
I have this too.
Same here. I think it's the glue on the back side of the display, because it doesn't show up on any other occasion.

Screen defect

Hello to all
As the title says it's another screen defect that this phone have
I have noticed a darker area, which make almost a perfect rectangular shape upper to left of the screen and it is visible only in some circumstances
- screen brightness need to be lower that maximum (the lower it is the higher this defect is visible)
- mostly visible on grey image (for example the market startup) see other images in the links

not visible at all on black screen of course but when the screen is off and with a bright light (sunlight of a power lamp) in some right angles I can see some darker dots (looks to be some kind of liquid inside the screen) at the size of 5mm and also this rectangular shape (good eyes need here ) no picture for this because it is not visible with any camera
I wonder how came to this and is any possibilities to fix this such as those screen burners, could these help? or only a screen replacement?
PS: phone have no waranty
Thanks
Screen burns are permanent on AMOLED as far as I know. You'll either have to live with that or do a costly screen replacement.
Ah well, guess I have to live with it, not a major problem but it's looks a bit ugly sometimes.
Just read a bit more about amoled screen burn and it seems that the blue leds are the most that probably get weaker in time and causing this screen burn, and yes this is an explanation why on a blue screen this is almost not visible no mather of the screen brightness
Maybe burn all the screen with a white image, but I believe the result can be worst that this
Thanks

Blue Vertical Lines In Sunlight

Hey guys. Was out and about the other day and was using my phone and as I tilted the phone down out of the glare of the sun I noticed some weird vertical lines on my screen. Each evenly spaced same colour etc.
I can not replicate the effect unless there is large amounts of light or im outside in real light. BEAR IN MIND ITS ONLY VISIBLE AT CERTAIN ANGLES.
The lines don't appear on any pictures or hinder the video. They ar only visible during sunlight.
What im wondering has anybody else got this I will say issue. Or any insight as to what it could be? If there's a problem Carphone warehouse will want to repair it and not give me a swap for a new phone. What light does anyone have to share. Or am I just being paranoid?
My Titan is exactly the same, I think its just the way the screen works and is nothing to worry about.

I've got mine from Carphone warehouse. Haven't noticed this yet. They will replace it for you within 28 days. Else it goes to HTC for repairs. However, where did you find this sunlight? It's been so gloomy out here. BTW as mentioned above, this could be just the normal screen behaviour. The other two issues with screen that have come up so far are - the pink dot in the middle and grey keys visible on white background. Nothing back from HTC.
Hold your Titan with the screen directly facing you, at about 3/4 arms' length (as in, just sorta normally with your elbow bent a little) under diffuse light, with the phone powered up and the screen off.
Then tilt the phone backwards. As you get about 3/4 of the way back, you might see a regular pattern of thin stripes running up and and down on the screen.
They are not visible when the screen is powered up. I think it's just a normal part of the way the LCD panel works. As an analog, on my Dell Venue Pro, I could see a grid of dots under its AMOLED screen when looking closely at an oblique angle similar to as described above.
I also have a matte finish screen protector on my Titan, which might be making this more pronounced. In any case, it is absolutely *not* happening when the screen is powered up -- even in black areas of the screen.
Hmmm... Maybe it's a future charging grid.
have you guys noticed anything new in regard to htc amaze blue lines. i just go the phone a week ago and i have been noticying the same things. any new info thank.
My Titan also has these blue vertical lines, and it is seen only in daylight with screen off.
I see the same too but I thought it was from my screen protector...

pinprick-size spots visible on screen in bright light

I've recently noticed that in bright sunlight I can see pinprick-size white dots scattered randomly over the screen. They're not surface imperfections, and they're only noticable in direct bright light (don't show up as blank dots when viewing screen in the shade).
They appear no matter what app is running, and at all stages of the boot process, so it's not a software issue.
What the heck are these? Is there something wrong with my device, or is this just a side-effect of the manufacturing process?

i am going to guess that it could be dust or other small particles. unfortunately, only way i know of to remove them would be to take the device apart.

[Q] [HELP] I do not know if this tiny light on front screen is normal ?

I just purchased a new Xperia Z2 (D6503), everything worked fine.
But I noticed there is a tiny bright light/spot looks like this "-", about 1-2 mm long, located at the left corner of the bottom bezel (which is all black) on the front screen. It is most noticeable when the screen is on. When the screen is off, this tiny light is also off, just looks grey.
I wondered what this light is for , and found no results in the user manual. I searched Z2 phone pictures online and all the bottom bezel on those phone looked whole black without any light. So i'm worried if my screen is defective.
Please help me check if you have the same light on the bottom left corner of the bezel.
Thank you!

I'm new to this phone too, but I don't have anything like you describe. I think you may have a faulty device.
Maybe damaged pixel? Not sure, but I'm sure it is faulty hardware, take it to Sony for warranty repairs.

Is it on the display or off the display?
That wasnt clear to me?

off the display , in the black bezel region at the bottom of the front of the phone.
It is most likely a manufacturing defect where the the bezel was scratched on the back side. This causes light from the backlight to bleed through the glass when the display is turned on. Sorry OP, maybe try to exchange it?
