I have what look like large circular spots amidst a cloudiness on my captivate screen. I guess the spots are actually a lack of that cloudiness in circles.
Its weird, just wondering what I did to mess up the glass.
My phone is quite usable, and you can't really see them during your average daytime use, however they are noticeable at night under artificial light.
Is it moisture inside the phone perhaps?
Or did I spill some kind of chemical on my phone?
Any ideas/should I be worried? (The screen has been like this over a month and the phone still works fine)
Thanks!
This is interesting, I got my mom the HTC One about a week ago. She took it hiking with her and was carrying it in a protective case for hiking. She was up ~10,000ft when she stopped for a break, pulled her phone out, text a few people, sat it down for about a min in the protective case, picked it up and the screen was shattered.
Anyone ever have any thing like this happen? I thought the elevation alone wouldn't do that, but then I got to thinking, airplane cabins are pressurized so your ears aren't popping and such. The temp at that altitude was a lot cooler then where she was when she put the phone in the case initially. I am wondering if the combination of cooler air and altitude caused it to shatter.
Here is a pic. I am baffled.

Wow. That sucks. I think you might be right. Maybe the glass expanded/contracted too much at that altitude.
Maybe it wasn't the cooler temp, maybe it was the lower pressure. I doubt the glass contracting would make it shatter like that.
However, you have a valid case of design flaw or manufacturing defect. Tell them exactly what happened and show them that the glass has NO IMPACT POINT.
Keep bothering them until they give in.
There was this other guy here, called @maseo, can't find his thread now on mobile. He got his one replaced eventually

Glass is not good at holding temp and pressure differentials... That's why u r cars glass is mixed glass ( mixed glass is less brittle and doesn't crash on your face etc etc) and airplanes windows are completely plastic and that's why most drink manufaturers avoid using glass except liquor because freezing point of liquor preety darn low so pressure is not an issue.. . Gorilla glass is actually very brittle so lower pressure and decrease in pressure is not somethin it can stand

I have never heard of this happening, but Gorilla Glass gets its scratch resistance and toughness through a manufacturing process that creates a lot of opposed stresses in the material. Changing the environmental conditions enough to throw those stresses out of balance could very well cause the glass to crack like that.
OK, despite all adversities with the dock and connection I've had with my TF701T, I'm still very happy with the tablet part of it (despite some software qualms). But this morning when I was clearing out my tablet's screen (by breathing on it and wiping it, I know, not the best thing to do) a spot appeared on it. I've had such a spot come up before but not as large and it would usually disappear in a few seconds. But this time the spot persisted. For a whole day (around 6 hours). I read up on a thread about moisture getting stuck under it but it should evaporate quickly. I thought that the glass might be bent to touch the matrix below it but I dared to turn on the screen and it worked. The spot is less visible on white backgrounds. Here are 2 pictures:

Does anyone have any idea what this might be? Moisture build-up? Bent glass? How do I go around fixing it? Will they accept my warranty or just tell me I broke it myself?
Probably moisture. Just using it (screen on) should take care of it after a while. Or you can try a hair dryer (lowest setting), but don't get it too hot.
I don't think they would fix it under warranty. Unless you have a 3rd party warranty like Squaretrade...
I came back home after a night out just after I posted this thread. I saw berndblb's post and intended to do the blow dryer thing in the afternoon but my tablet was OK when I was back in the early morning. Apparently it was really just moisture and it was alright on its own. I just hope this doesn't happen again. I don't like the idea of having my screen getting wet and probably getting messed up. Good thing I don't live in a jungled area, lol.
This happens to my TF701 as well, fairly regularly. It's not moisture, it's the glass making contact with the touch matrix. I used to somewhat consistently get rid of it by just blowing into the charging port, which would loosen the glass (and disprove the moisture idea as well). Now, I just bend gently from each side and upward in the middle and it unsticks immediately. I also noticed that the upper corners are somewhat loose, which is what leads to the bending in the first place.
It's probably just ASUS's terrible quality control on the TF701. I basically had no problems with my old TF300, but the TF701 and its dock have been riddled with issues and defects.
Thanks
Thanks brother, i just bought windows 8.1 tab in rainy season. My city is hot and humid, so in 2 days i found a big dark spot due to moisture in the center of screen. I read your post and did the same, and got rid of it in just a single blow....... Tanks once again....

Before I installed UV screen protector I noticed this stripe under UV lamp. Is that normal?
I saw that too, when installing the Whitestone Dome, and have not noticed any problems.
I noticed the same thing when installing my whitestone... assuming it's normal, my display is good under normal circumstances as far as I can tell

it's basically the same shape that shown on my screen whenever the screen display dark color contrasts (but not true blacks)...that seems to resemble a burn-in.
Hi everyone, I don't think this is anything to worry about. I found the same blob on my Huawei Mate 20 Pro whilst I was trying to cure my green screen.
I then checked my partners s9 and it also had the same blob so it's definitely not screen burn.
I was told it's the loca glue used in the manufacturing process. Same thing on the Pixel 3 XL's and Note 8's. I wouldn't worry about it.

Theres almost no way it's a burn in. I have this on my brand new unit that i noticed on the 1st day of use before installing my Whitestone. At this point the screen and only been on for about 20 mins. I know this because my phone as of now only has 31 charging cycles on it.

Yup normal. However I seen a user on here who had it discolor and could be seen under normal use.
Been looking into it why I'm at work. It is an optical adhesive and perfectly normal. However from what I'm guessing Samsung let a few out with bad adhesive and that's what causesd his what he thought was burn in.
But normal to see it under uv under certain wave length's. If you see it without UV light then that is an issue. Or if you have your display on and can see the outline of it.
Same Norland adhesive we use at my work on some of our optical stuff.
Just a heads up. The light they give you with the dome is not the right wavelength for the adhesive they use. Final cure you will wanna do 2 min total for each top and bottom. If not the adhesive will still be green "not fully cured" the adhesive they use is on the cheeper end of the spectrum but fine for what it is being used for. That much adhesive in a top of the line product would be around $30. But I used it on my. Did a final cure of 2 min top and bottom. Checked it out under a high power microscope and it was fully cured. No issues with it lifting.

So you've been meaning to say that if we see this without UV light (which I see in my device when I'm in a dim room and I let my phone show dark grey to dark green colors), then it's not normal? Then if it's Samsung fault, would they fix it in a repair center (hopefully free of charge)?
Im just quite pissed off for this since I came from S9+ and I havent had any issues with the screen. Couldn't they be at least consistent with things like this given the fact the display is one of the most selling point of this phone?
p.s. and oh, just to add, what's appearing on mine is not just some rectangular flat discoloration on my screen, it has dark polkadots lined in a grid inside just like many others have been complaining about.

note 8 had that too.
I saw the same when installing my dome glass. No issues with the display.
My 3 month old Note 9
Can see green polka dot kind of burn in during normal use. Phone is only 3 months old. I take care of my phone religiously. Just noticed a few days ago and now it's all I see.

My Galaxy M21 phone's AMOLED screen got damaged due to liquid penetrating a few days ago. I went to the repair shop and asked to replace the screen with LCD one.
After replacement, everything is working fine, except for the proximity sensor. It always reports far proximity even if I bring a surface completely covering the screen. During calls, the screen does not automatically turn off when bringing it to my ear.
I have asked the repair person, and he replied that the LCD screen does not have holes to accommodate the sensor properly, so it is blocking the sensor. But AFAIK if that's the case, the sensor should always report near value, not far.
Is there any solution for this or is this a known problem due to LCD screen replacement?
Welcome to XDA
Not really if the mobo doesn't support the alien hardware.
The firmware instruction set may able to be altered to get the new hardware to work as you want.
It been better to use the original display, but not doing so you opened a can of worms.
Water damage? Possibility of mobo damage as well particularly if the battery wasn't quickly disconnected. If it was salt or brine water it's already dead.

By water damage, I meant a small amount of water somehow got into the screen and darkened the screen slowly starting from one side (a common thing on AMOLED displays).
I can assure that the water didn't cause any problem other than the screen, because I regularly check the device stats & sensors. The proximity sensor is behaving like this after screen replacement.
Well the former of what I said then applies.
I'm surprised it will even function with an LCD.

Sorry to barge in friend,
Thats why I am very careful with 3rd party repair vendors, I have lost many phones to them, they REPLACE new hardware with old spare components,its a bad habit they have & thats why the OEMs have "Authorized Service Centers" exactly for this reason.
For Shamshung devices I suggest you go to Shamshung Authorized Service Center only as Shamshung parts are quite in demand because of good build quality.
Small Story: Few days ago I went to Shamsung Service Center to try to downgrade my M21 from A13 to A11 (my phone is within warranty) & as expected they told me "only upgradable not downgradable sir!". I knew they were lying because a friendly shamshung service center guy once told me they do everything there internally, they have repair softwares there. Anyway, so I took the phone to a 3rd party repair station and the owner named Salman told me he has downgraded so many Shamshung phones of newer models, all I have to do is leave the phone with him for about 10 hours & he will downgrade from A13 to A12.5 then to A12 then to A11.5 and finally to A11 so it will take time, NO! he was lying! He was charging me a biggish amount but not just that he needed 10 hours to fix the mess that would happen when he stole & replaced the new components with older ones. Thats why Authorized Service Centers only friend.
@OldNoobOne I already went to Samsung's authorized service centre, but they only can replace the screen with AMOLED.
I was desperately trying to avoid AMOLED screens this time because they get damaged easily and are more fragile than LCDs (that's my experience with them).
Don't know how much correct I am, but I have seen most AMOLED screens getting damaged completely due to the slightest of shock or due to a single drop of water somehow seeping into it. I have never seen this type of problem with LCD screens.
Looks like I should have bought a phone with an LCD screen in the first place.

Yes friend, not just that LCD screen phones tend to consume lesser battery too. Another way to avoid AMOLED issue is that is to use a plastic pouch during rains etc. (there is no problem in communications) or also use a flip-cover instead of normal plastic/rubber back covers only. Just use a good quality scratch/screen guard like 3D+ and LCD will look quite like AMOLED

That makes perfect sense. Using an aftermarket LCD display does not.

All phones should be kept dry regardless of the IP rating. As you found out the AMOLED diodes used in displays are water soluble. The displays are sealed but if the seal is breached by water they will be destroyed in short order. Always use a good case to protect from impacts and high G loading induced damage when dropped. Wipe all water off immediately.
This N10+ in my has always been in a good case and unfortunately has been dropped onto concrete many times (zero visible damage). It has well over 8k hours on it. The display shows no sign of damage or degradation whatsoever. Don't use in direct sunlight and use manual brightness keeping the brightness at 50% preferably less it will get many years of service.

AMOLED displays use -less- battery, have infinite contrast (pure black) and the best color gamut. Higher and variable refresh rates are also possible, but these tend to use more power.
They are more expensive and have shorter, finite lifespans. Other than lifespan they are superior to backlight LCDs. That's assuming you protect the phone from drops and the design/QC was good when manufactured. Of course display quality can vary from manufacturer, model and individual displays. It could be you got a defective AMOLED display from the get go. Samsung's QC has been slipping in recent years it seems. A used N10+ in good condition might have been a better choice than a new midrange Samsung. It remains one of the best phones Samsung ever produced.
LCD displays are easier and cheaper to manufacture so you pay more for AMOLEDs.
If you prefer LCD displays by all means use them.
They are more rugged but not bulletproof by any means.
(Always protect LCDs from solvent exposure like isopropyl alcohol; they are open vented to the atmosphere and solvents can poison/destroy them.)
