[Q] Samsung S3 screen won't work, help? >.<

Hi all,
Today I dropped my S3...on my bedroom carpet and although there are visibly no cracks or scatches on the surface of the screen when I went to unlock it the touch screen wouldn't work and there is a small black area in the top right hand corner. Just now I tried to see if it would work but found that the colour of my screen has turned to a blue hue
All the buttons are still working fine
The phone is still under warranty so would going the samsung service centre be worth a try?
or would I have to get the screen replaced or something, what are my options?
Any estimates on approx costs too are appreciated!
Thanks
Photos if that helps...sorry for bad lighting x-x

The screen will need to be replaced, take it to samsung. it won't be covered by warranty though

Keyboard afterimage/artifact left on my screen

I got my s3's cracked screen get fixed by this guy on ebay. (GLASS ONLY LCD WAS FINE)
But after I got my phone back, there was an afterimage of the keyboard left on the bottom of my screen. I don't see them that well in dark images but on white screens I can see it.
I heard afterimages can be left on AMOLED displays if the image is left on (without refreshing) too long. I think when he was testing my screen, he left the keyboard on for too long. And I also heard this was a permanent mark.
So I emailed him and he replied that this indeed does happen while replacing the glass and his customers have reported this too and this does go away after a while. But, I thought these image artifacts were permanent. O_O Is he just telling me this so he wouldn't have to replace my LCD(which would cost 100~ dollars.)
1) Does this go away? 2) If so, how long does it take ?
2)Does this actually happen when replacing the glass?
Thank you so much!

New lg g2 out of the box faint white lines all over the screen, normal or not ???

I have a lg g2 out of the box faint white lines all over the screen, and i'm wondering is it normal or not ? I read a little today that there a 2 kind of screens out there. One screen is ok and the other has these white lines on it. I'm not sure if this is a defect or not. Some say these white faint lines are actually the digitizer visible on screen befause of the fabrication process. Other say that its kind of a defect and should return the product . My question is what is the truth ? is this a defect ? can it get even bad than faint lines in time ? or they will remain just faint lines ? Its not a deal breaker for me just yet , but if someone tells me that this will get bad bad I will return the phone . So please I need some imput
Do you mean those little Squares that make the screen look like a solar cell?
no , white vertical lines from top to buttom all over the screen , mostly visible on a white backround and open colours , they are all over the screen like a pattern , vertical , from top to buttom , very very faint , I can barely see them but they're there
nope,not normal. Faulty display. Send it to warranty. It will be replaced
Mhm. I do not have any of them... I would send it back for return... But maybe it's not bad at all.
Cause I read there a 2 types of panels lgd and jdi , one doesn't have these faint small barely visible vertical lines and the other does mand lg doesn't consider this a defect , that's why i'm so confused ), I've driven 2 a show center and played with one that's on display and I saw the lines also ...diffent store ) weird
Return, Now!
If u have a grid pattern that's normal. If u have two white lines u have a refurbished phone with wrong panel.
Have the same problem. Ordered the phone 2 weeks ago and since the beginning it has a small whitish smudge/spot on the left side of the notification area and 2 irregular parallel lines mid screen, under the first smudge. Visible most of all on a grey screen.
I didnt notice them at first, but in the right lighting at the right angle I can see white vertical lines.
As this is about .01% of the time, I'd say its normal. If you can see them more, send the phone back.
not normal for sure.I got mine replaced for the same problem..

Screen Backlight on Border Of My Screen ?? why ??

I notice screen Backlights on borders of my screen !! Is that a problem or normal ??
You are not alone, I have really bad back-light bleed issues as well as image retention. It's all the way down the side of my screen and there's even a little bit in the middle. Seems to be a common fault on the LG G5. Money is going to have to come out of my pocket to replace the screen. I only bought this G5 online three months ago. Ridiculous.

Horrible dots on camera screen and on pictures

Just got the wife's S9+ back from screen repair and now there are horrible dots on any pictures that are taken using either the front or back cameras. They are on the screen even before taking any pictures and then show up on all pictures no matter the lighting , angle, or anything. Has anyone seen this? Is it a known issue or do you think something happen when the screen got broke (was smashed in car door but only the screen was broke not the body or anything. It was in an otterbox) or could something have happened when they replaced the screen?
