[Q] Tiny white object under the glass screen? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Bought a Galaxy S4 on ebay a few weeks back. Didn't notice it at first, but when I sat down to apply a screen protector and wiped the screen clean, I noticed there is some sort of a micro object, like a white dot just under the glass. It is not a dead pixel, because it is there when screen is completely off, and when I tilt the phone and hold it at an angle I can see that LCD under this tiny dot is clean.
What the heck can it be? I doubt the seller changed the glass screen and wasn't careful when cleaning the LCD, but I suppose it is remotely possible since the phone has a nasty scratch with tiny chunks of plastic chipped off, on the bottom right corner of the silver bezel.
Anyone had a problem like this with their screen? Any way to fix this short of removing the screen?

Could be dust under the screen. If I was you I'd get it replaced if it bothers you. I dont think there is no way to remove it other than removing glass to clean it and reapply which I advice against.

scratch on screen

I have a scratch on my screen (Imate Jam). The scratch is just on the plastic layer. The glass isn't damaged. Is it possible to remove the plastic layer, without losing the touchscreen. Where can I order a new plastic layer (not a screenprotector, but the plastic layer wich you can only remove when you open the device).
Yea, i have the same problem. Two-three minor scratches that can only be seen on white background. Is there a way to fix it, or even change the plastic layer as koole said??
If not, how much a new tooch screen costs?
The plastic layer you're talking about is actually part of the screen and the only way to replace it is probably to replace the entire screen. This is why almost everyone is using a screen protector.
Adding a screen protector may be the solution to your problems. I had a few ugly marks on my first ppc before I got hold of a screen protector, and it almost totally hid then scratches.

Front glass damage - gap between glass and substrate, seems like delamination

I have dropped my S4 a few times, luckily most of the times it was with the ultra thin plastic case. Case did the trick of stopping the glass shattering, but I've noticed an irregular shape appearing beneath the glass in the upper right edge (where the phone has fallen once). The irregularly shaped blob has different colour than the rest of the blue bezel around the screen, it seems that the screen has delaminated from the blue background layer on that part. Phone works without any problems.
Has anyone else been having the same problem (I've seen it also on my colleagues S4, same reason), and is there any easy way to fix it (applying heat/pressure to the delaminated part or something similar)?
The glass digitizer screen is stuck on to the LED screen behind it with an Optical Glue.
I wouldn't think that a small part would come away like that, more likely you have damaged the LED screen.

[Q] Colored backing behind glass peeling

The colored checkered backing behind the glass is starting to flake around my home button. The phone still works fine, just to the left of the home button no longer has the checkered white (kind of like carbon fiber look).
How thick is that colored backing? Is it just a thin paper sticker on the backside of the screen? Does it serve any other purpose than just to make the phone white (or whatever color)?
If this is cause for concern, I was going to take it to a cell phone repair place to get the front replaced.
Thanks,

[Q] Problems after replacing LCD and digitizer. Help needed.

I recently broke my 1 month old S5 LCD. Outer screen is just fine, but the LCD has paper thin glass, and it unfortunately met it's demise after a misplaced toss. I ordered a new LCD digitizer assembly and screen adhesive, then disassembled my broken phone. When I disassembled it there was either adhesive, or gasket material that was on top of the plastic flaps that go around the back and recent buttons (I assume adhesive), and also around the home button which I assume is important for functionality, and for water resistance. To make a long story short I assumed that this material would be provided with the screen adhesive so I removed the material from the back and recent buttons (it was already slightly damaged on one, and almost all peeled off of the other. I left the home button material because it seemed weak and I didn't want to break it. Also, some of this material had been peeled off/torn off surrounding the home button. After reassembling without the adhesive/gasket in these areas my phone now presses back or recent at random and it makes the phone almost impossible to use because it will exit out of programs or just start doing crazy stuff all on it's own.
My question is, is there somewhere that sells the adhesive/gasket for these three locations, if so where, and if not are there any suggestions of an alternative to the stock material. I am wondering if anyone has had some experience with this issue could chime it. I greatly appreciate any help.
Sincerely,
Dustin

Phone screen starting to delaminate - fixable?

As above just bought an S5 second hand and the last owner said it was because of a gap between the screen protector and the glass.
I removed the protector and found it was between the glass and the black backing to the right of the Samsung text. You can press the glass and the gap removes showing black again, but it does seem to be growing.
Can this be fixed? If so how?
