Weird Screen Issue - Layer Missing - Huawei P20 Lite Questions & Answers

Hey all,
I have a very strange issue with my P20 Lite.
When the light hit the screen in a certain way, I noticed thatthe top right corner of the screen seems to be missing a layer.
The majority of the screen is just black, however the top right shows a pattern. I assume this is the capacitive touch layer.
When the screen is on, it is pretty much not noticable...
I have had a glass screen protector on the phone since day 1.
The attacchments show it pretty well.
Any idea what has caused this?
I assume replacement is the only 'fix'...
Thanks

Purple spot on screen

Hi guys, I just found a purple spot on my screen. Just a little smudge, barely visible (not at all in normal use) but it can be seen when the screen turns white. Is this a HW problem ? And can it be connected with dropping the phone before a week ? I assume that it would have appeared adter the drop, but it appeared today, I'm 100% sure that it wasn't there yesterday when I was reading + the spot is in lower right corner and the only little sign of the drop (nothing is damaged,just the corner of the phone) is on the upper left corner, where it hit the ground. I've never had any problems with my phone,for over a year now. Runnig CM10+Siyah.
thanks

A pic would help too... Did you try connecting it to an external display, Most likely a screen burn because the amoled screen is very hard to break you only break the glass in front of it usually. Maybe screen wear how long has it been since you bought your phone?

hi, thanks for an answer. this is the photo, like I said, it's barely visible on it.. but I also think that it hasn't anything to do with the drop. it is a year now, with heavy (really heavy) usage.
edit: the scratches are just screen protector and it is not problem with it, I tried to remove it.

Does anyone here NOT have light leak?

I've been suffering the dust issue on 2 lumias now, and have noticed something. If you go to a darkish room/area and tilt the phone, you can see the light from the backlight coming through on the sides of the screen and also at the top and bottom by the capacitive buttons.
e.g. http://discussions.nokia.com/discus...ith_Windows_Phone/30650/1/2012-12-15-1679.jpg
I'm just wondering if there's anyone here who can go to a dark area, and see whether they all have this or not? Kinda worried me because made me think there's a manufacturing defect here and the screen isn't secured properly on the handset - which could maybe account for dust getting in? It might also explain the 'rattle' on vibrate that some are getting.
The three lumias I've seen all seem to have this to a certain extent (the light on the sides is usually much thinner and normally on either the right or the left - not both).
ANyone?

Funny enough, I had mine sent in for repairs due to scratches on the screen. After having the screen replaced I have NO light Issues and no more dust issues.
Seems during the initial build the screen is not fitted in or glued in properly ?

Oh christ....don't know what to do now. Could either wait until a new batch comes along without this issue or buy one now and send it off to Nokia. I'm rather depressed about the prospect of sending a brand new product away to be opened again

You GENUINELY have none? I.e. no thin strip of light running down the side(s), no light just above and to the right of the windows key? None above the search key? NONE?!
You must have been sent Elop's personal phone. I've looked at around 6...not that many admitedly, but all from different places so the maths of it all as coincidence is bleak.
Treasure it my friend.

no leaks here either... the only issue i have is the dust in the FFC.
No leaks (or dust) here either.
I really tried to find any kind of light leak, but found really nothing.

Must be a lucky one here. No light leak...or dust. (Whew)
OK cheers guys....well I guess either I'm having a psychotic episode or the unlocked batches ive looked at in the UK are defective.
Thanks anyways x
How would you define the light leak, eg, if I look at the screen on a very extreme angle, I can see through a minute gap at the bottom and see light from those buttons through it through the screen, but in normal circumstances it isnt noticeable at all. like the light isnt uneven or anything like that

Well it's like in the picture link that I put on the first page - Except as well as the top and bottom, there's also a small amount on the sides too that can be made to partly disappear if you push down hard on the screen there - I.e. the impression the glue holding the screen down is loose. It appears on all the ones I've seen, but I don't know, if you guys say you haven't seem it maybe I've just had extraordinary bad luck! It doesn't affect the screen when looking at it normally but it makes me worry for the future - loose things tend to become looser with time, and my theory is this, the dust and the vibrate rattle are interconnected.
I'm looking at my 920 and I think I see what you mean. On the top I see the light across almost the whole top but not at the sides or bottom. Is really a concern (I don't look at the phone at an extreme angle like that..)

Oh ok sorry, I didn't look at the pic. The vibration rattle (from what I've read) is just how it is because of the kind of vibrator (for lack of a better word I can think of) technology. Would have been good to have a nice clean vibration humm being a flagship phone...
Nothing seems to change for me when I compress the screen. Perhaps you really did just get a bit of a dodgy one?
Me either. I just did it again to make certain I wasn't lying to you. I cannot see anything from any angle. Now I'm starting to feel a little guilty.
I'm on my second 920 because the first one had a problem with switching back to handset mode after unplugging a headphone jack, but neither of them have any light leak! Maybe it is a manufacturing defect because of rushed batches due to the supply problems?

No light leak, but there are dust under front camera and once in a while the proximity sensor activates all the time.

Can You See Screen Scratches?

Hey folks,
I'm looking to buy a used phone on ebay. The description says that the screen has a slight scratch on it that can't be seen when the phone is turned on...only when it's off. Having never had a scratch on any of my phone's screens, I can't easily verify that claim. Does this have the ring of truth to it?
If you've had a slight scratch on your screen, does it really only appear when the phone is off? What about when the screen is dim? Or what about at different angles, etc? Does it pretty much always just disappear?
Thanks

I have a few scratches in my screen that are really only visible from slight anez, when the screen is off,and when the screen is solid white
Sent from my HTC6435LVW using xda app-developers app
I have super tiny (1/100 of a millimeter in width) ones that are only visible when the light (only direct sunlight) hits it just right, other than that I forget that they are even there
Probably from being placed in a pocket
Awesome. Thanks guys.

I even have a dent on the screen and it's barely visible when the LCD's on, so a hairy scratch that won't be noticed while the screen is on sounds like true
I had a small crack in my screen and I never noticed it while using the phone unless you really look for it, small scratch you will be fine won't even notice it

[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?

Typing issues on SM-965F

I've bought a used S9+ like 3 days ago and run a QA test inside the phone. The screen was fine and it responds normally, however after 2 days I couldn't use a keyboard because of its issues while typing. Basically, when I'm typing a longer sentence, I have to either slow down or sometimes press a button 3-5 times for it to respond. It stared to occur yesterday and I don't know if that's the touch control issue or something with the display. P.S. I've tested it on Gboard, Samsung keyboard and Grammarly keyboard, all with the same issue.
Is there any fix I can do without paying for a new display? It will cost me the same amount of money as the phone itself.
Thanks!
Are you using a screen protector? If not, try it. Maybe touch sensitivity is turned on in display settings, try changing it to see if it's better. I've noticed that on some screen protectors, they retain a lot of humidity so I have to constantly clean the screen to get rid of "ghost touches"

No, I don't use any screen protectors. My phone has a Spigen case, which is slightly over the screen both at top and the bottom. I tried to turn on and off touch sensitivity and it didn't help. Funny part is that it sometimes stops and goes again.
Had this myself, especially with the space bar ?
Same here, have to press space up to three times (intermittent issue). Screen protector on, sensitivity does nothing.
