[Q] white dots on screen in black background, also when watching a video

Hi,
I am seeing 2 single white dots on left side of my phone screen. I like Galaxy R beacuse of its specification. But same time I was worried about its screen size as I am too used to keep phone on left front pocket of my jeans pant. When I drive 2 wheeler I see sometime it gets pressurized. I don't know how else I can keep this phone with me.
So the question is, did my phone create any dead pixels just because of it might have got some pressure? Anyone can help to know are those really dead pixels and how to fix them?
I can only see them when camera switch on/off and display for a moment becomes black or when watching video. Otherwise with full colour background wallpaper, dots never be seen.

Well as we have lcd screen, i dnt thinkk that problem like dead pixels in amoleds can be happen here (correct me if i m wrong)
try flashing stock rom and wipe cache and dalvik cache, may be it help. Do update ur prob resolved or not.

i don't think they are dead pixels, it may be because of dust.. similar thing happened to my friends Optimus One because of dust..

First let's confirm its not due to the background of the picture that was on your screen.
- Type *#0*# => Press Vibration(Black) => Now check if there are any White spots.
- If there are white spots on the screen then take it to the service center and have it checked, if its just dust as guys above me have mentioned then they'll clean it.
- If you can't see any white spots then it was the background that you were talking about which had white spots & nothing is wrong with the screen.
Hope this helps.

I have a similar white spot... well, i am saving that one, given that the R is now out of stock, if we dont see an ICS build or if samsung says they can't get to update it to ICS, i am gonna take it to the samsung centre and ask them to change the screen as i am getting that white spot and because of no stocks, i am sure i will be getting my refund

Even I had a white pixel on the left hand side of the screen on my SGR. You can observe it only while having a dark background. I read online that its pretty common so I left it.
You can try an android app - "Pixellator" (?!).. I am not sure if thats the name.. It has been made specifically for such white pixels.. Its dint work for me though... But no harm in trying

Thanks for this information. I was not knowing such hidden interface. I did above test and found no white spots. I am actually confused now. I do have scratch guard on my screen. Don't know but those 2 white spots can be seen randomly only when black background is on screen.

Then it's the background's problem .
I know CM7 has such a system app called CMWallpapers.apk , and they have the choice of setting it as "No Wallpaper" . Can you try extracting that from the CM7 ROM and giving it a try ? Don't know if it works though *shrug*
This was sent from a Galaxy Ace. Problem?

try turning on the brightness to max and then do the vibration ( black) test...
then you can see them easily...
it is there in my case...

Switch on the camera and cover your camera & manually turn off the flash. Now take a picture it would be completely black.
Do update on the progress here.

I can now see those 2 very small white spots at the same place. Do such spots are problematic in future and should be fixed at service center soon? Do they will fix this under warranty?

If u want u can raise claim and yes they will fix it for free as its a display prob and ur phone is in warrnty period.
Before giving in ssc ensure that u have flashed stock rom of ur country, ur download counter is zero and ur phone is not rooted.

i had my Samsung tablet 8.9 since January and all of a sudden i noticed a white spot on the screen. it appears as gray when the device is on and the screen is white and it appears as white when the device is off or the screen is black. has anyone encountered the same problem? what is it? and why it suddenly appeared? how to solve it?

it is a normal thing. almost all lcd screens have approx. 0.03% dead pixel in whole screen even if it is new. there is no point to be worried about this.

[Q] Screen ripple

Hello
I have noticed that my Moto G (1st gen) has a problem where if you touch the screen you can see a "ripple effect" in the center of the screen, it's get more noticeable as you press harder, but even if you press light touches it's still visible somehow but very little.
I have searched the forums and found people having this issue with the 2nd gen of the device: http://forum.xda-developers.com/moto-g-2014/help/screen-question-t2947732
here is a picture of the problem some guy posted (in my device it's always presents in the center of the screen no matter where i press):
http://forum.xda-developers.com/attachment.php?attachmentid=3036129&d=1417076320
Can you please check if your device has this problem too?
Make sure brightness is highest and test in while you viewing black image: http://images2.layoutsparks.com/1/230004/seductress-plain-black-page.jpg

Bro it is normal. LCD screen/ 1st gen/2nd gen/ bla bla.. Manufactures these days are focusing on QHD/Full HD/i dont know what HD and they have no fix for this "problem". It is very normal that you have this, so dont bother with it and dont change for a new one! I had 2 LG G2 phones same problem, I bought the G3 same ****, live with it

I know LCD screens have this issue, but I suppose in phones they had to deal with it somehow.
what's bothering me it's that if it's more noticeable if i press the middle of the screen, the bottom and top parts seems less affected. like something is applying pressure to the middle of the screen (the battery maybe ??) I'm also seeing the "ripple" when I'm applying pressure to the M logo at the back of the phone.
Shame that even G3 has this issue who even cares about QHD lol, 720p is more than enough even for 5.5" screens.
Thanks for helping, I would be grateful if more people can check this out.

No bro, not the battery problem(no pressure), it is the way they made the phone.. Each LCD have his own "ripples", just take an app like linkedin en take a blue background you will see how sick the ripples are. Im also irritating a lot but really leave it dont look at the ripples

I've never had such a problem before with any touchscreen electronic ever had from resistive to capacitive touch. I did try to press really hard on the center of the screen of my Moto G and everything that happens is a slightly distortion because the glass is touching the pixels but not what you reported. What I noticed is a tiny bit reduction of the brightness every time I press the screen but is so minimal that you have to be in a pitch black room and pay a lot of attention to it. So I guess you could return the phone as defective or change the display if you're able to do that.
P.S. the pic you posted is not a total black image so when I turn the brightness all the way up I see something even if I'm not touching the screen. I tested with my own made really black pic and I have no issue whatsoever.

There is no way you really pressed hard and nothing happened.
If you would have pressed hard the ripples should be clearly visible, this is how LCD works and it's known. every phone with LCD I saw would ripple if pressed hard enough. My problem is that it's visible another normal usage in a dark room.
Are you sure it actually reduced the brightness? it supposed to be brighter. it will look like a white stain like in this picture: http://forum.xda-developers.com/attachment.php?attachmentid=3036130&d=1417076320. And yes the picture is not really fully black I found it on google and from my PC it looked blacked.

But why the ripple happens in the same spot? no matter where I press it's in the same location (in the center of the screen), that's makes me wonder, because in LCD's it's supposed to ripple where you touched.
Do you have a Moto G 1st gen too and actually sees this with regular taps? it's changing based on the tap location or it's fixed?
Thanks for your help

Because it is sensitive there?? It is rippeling on every spot where you touch buts on some ares it is more sensitive i think(close to the layers, especially in the center of your screen).
I own a LG G3 and before 2 LG G2 's. So i know what ripple means . Check the Z3 of Sony same ****.

White dots on screen after replacement.

Hi guys,
2 weeks ago I replaced my nexus 5 screen and battery. Everything was fine till I noticed some white dots on the screen. I don't know whether I should make a complaint letter or do something with it by myself. I read that it may disappear after some period of time but I'm not sure about it. Do you guys know what is it? And how could i fix this? ;c
I also have a photo of the screen but can't add this here because I'm a new user...

if you mean discoloration, (some screen areas brighter than others) you should try to get a refund and replace the screen if possible

Your blurry screen isn't going to show up in screenshots. Your screen is water damaged and you are going to have to get a replacement device.

before some time there was pink colour spots like colour bleeding on down of screen and now its gone and now the screen is lil blur so should i keep it in rice or do some other technique to get it sorted and i also heard that there may be some part inside it which is shaken by falling and can be fixed ? or i need to change the display itself ?
i havent gone to service center as i thought if it can be solved without going there and when i am opening the sim tray i cannot see any red mark so plz let me know what is the best thinhg i can do ?

You could get the screen replaced but you'll have to find an OEM part, order it, and then take it to a shop that will swap the screens out. I think you should just get the phone replaced completely as other issues could show up later given that your screen is already damaged.

Blue Dot on HTC U11 Screen when displaying dark images on screen

Hello everyone.
Has anyone who owns an HTC U11 noticed a blue dot on the screen when displaying dark images or black background? Please see the attached images and let me know if your device suffers from the same symptom. In order to check it fully, just download an app called "Black Screen" and run it. It will show a black screen, which if your screen is affected, it will show that blue dot.
I have emailed HTC UK and i am still waiting for a response. It's a shame to see this on such an expensive device, especially from HTC.

Hey there,
My bf recently gotten his HTC U11plus also faced the same thing, can I check if you gotten any response from HTC on this?
Thanks in advance!

Hi. I ended up sending the phone to HTC under warranty and got the screen replaced. No more blue dot!

Thanks!
Hey okie noted!! Thanks a lot for ur reply I will get my bf to go to HTC as well!

Maybe a dead or stucked pixel
