I don't see anything wrong with it. Just sensitive electronics.

Hi ,
please help me my XDA is fell out of my hands & hit tge wall .
Now the screen is white with some other colour with orrizontal line .
the screen don't have furrows and breaches it seems intact.
Some help please.
It could be that a physical portion of the TFT screen has been cracked. That would explain the horizontal discoloration. You'll have to have the PPC opened up to see if there is any heavy damage to the display itself or if it's the plastic plate covering the display that you tap with your stylus.

Actually from what the o.p describes it may just be a loose connector - the scrambled picture / horizontal lines sound similar to the 'self test' lcd function on ipaqs, and they said there was no physical damage.

I honestly don't know since I haven't opened up my MDA II before. I can't say if the LCD displays for the XDA and XDA II are identical. If they have the same dimensions, then they probably are.
Good Luck

Sent HD2 for screen repair, returned with non-glass screen.

My HD2 was developing an issue with it's screen, white patches were appearing. So I sent it off to O2 to be repaired, and while the problem has been fixed, it's been returned with a non-glass screen with no diamond shaped etching on it like I had on the original.
Anyone else had this?
what do you mean by diamond shaped etching? and is it still multitouch?
If you look closely on the HD2, the screen has fine diagonal lines etched on the glass which cross making what appears to be diamond shapes on the screen. The screen on mine isn't glass now, it's plastic and those fine lines aren't there. I was just wondering if anyone else had had a repair and had the same thing happen.
It is still mutlitouch. I'm just trying to decide if I should complain.

Are there any other notable differences? Is it more easily scratched, less transparent, more reflective, etc.?
If so, then yes, you should definitely complain.
as plastic is alot more prone to scratches, i would complain...

I understand this must be really annoying for you, but tbh I find it really interesting.
Is your new screen still capacitive? Does a normal stylus or other object still work on it? (ie. is it still resistive?)
I never realised you could get multitouch plastic screens....
i would definitely file a complain. you bought your hd2 with a glass screen and its weird that its plastic. yes there are diamond shaped etchings in the glass screen.
so all capacitive screens should be glass covered? hmm... interesting.

I had mine repaired and yes, the lines seem to be gone. I think this has to do with the improved hardware and not because its plastic.
f*ck that. complain, you bought the hd2 and you want it back the same way you bought it.
WHOA!
This is either a HUGE insight to something about the amount of screen blotches being received.
or
You are dealing with a crappy fix.
I honestly have never heard of a PLASTIC CAPACITIVE LENS!?!?!
Will this be a common resolution to HD2 shatter/blotch?
there are capacative screens with plastic face...
the samsung f480 has one either
Hmmm

That's good to know, maybe I'm wrong about it being plastic although it doesn't feel the same. Is your's definitely still glass?
Why not post some pics here ? Wanna see it. Best would be to do the pics in various angles to a light source to see what consistency it has ............
I noticed the diamond etchings on my HD2 straight out of the box brand new, still glass though.
may be we should look at tmob us screen and see it's type

All capacitivie screens are made of glass - or else the technology wouldn't work since its basically a grid with electric current covering the screen, and this grid you disturb with your fingers. Plastic is NOT leading electricity so it would not work. And btw, the Samsung F480 has a Resistive touchscreen.
That's not strictly true. Neither glass nor plastic conduct electricity - but both act as a dielectric for electrostatic fields. A capacitive touch screen can theoretically work with either plastic or glass (or even air), because capacitive touch doesn't actually require that you touch the screen.
glass conduct electricity
Strictly speaking, hardly anything conducts no electricity, it's just a question of a material's resistance and therefore the amount.

General question about touch screen of the HD

Hi I have bought a Blackstone on ebay,I have noticied that the touch screen have a little gap between the top of screen and the screen below.When you press the screen going down for about 1 mm it's normal?, I don't know if you understand me, my english it's very bad...

The Blackstone has a plastic guard over the 'actual' screen. This will push in slightly. Sounds fine mate.
Regards
It shouldn't be like that. True, there is a tiny distance between digitizer and lcd, but NOT 1mm

I daresay there was a bit of an exageration in the original post to be honest, i agree with what you say though. How would you explain it to someone if you had the issue? The screen goes down 0.15mm? A bit hard to assume in these cases i believe. It seems exagerated, If it really was 1mm, the cover would be away from the phone yes?
1mm it was a approximate distance, may be it's less than 1mm I think, but you confirm that it's present a little distance between the first layer of the screen and lcd.
Thanks

Yes mate, there is a slight gap between the screen and digitizer.

Poor construction of left/right sides of the screen?

Hi there!
Is anyone here having problem with the left and right side of the screen? When I slide my finger on the screen to the outside of the phone then I feel under my fingertip that the screen is a little bit under the body and with my fingertip I hook up some plastic part which seems to be between screen and aluminum body.
I hope I explained the problem
Anyone with the same issue? Is this a hardware issue or just stupidity of the HTC engineers?
Have you thought that this may have been done by design?
For those that put their phone screen down the screen is slightly raised off the surface thus not getting scratched......
mine is the same... i believe it's the design so you don't scratch the screen when it is face down
I prefer not putting the phone down the screen rather then having this unconformable feeling when I move finger on the screen...
Solution: Get like 3 or 4 screen protectors and lay them all on top of the screen at once. The thickness should bring them in line with the plastic rim and your fingers will no longer have to suffer the horrific feeling of a 0.2mm plastic ridge
My physical glass/plastic screen seems to be stuck further down on the top left and bottom right corners making it slant upwards to the other corners. I push the top right down and it seems to feel loose.
Is this what your issue is? because this is whats happening with mine.

Cracked screen repaired now having touch problems

I recently had my Galaxy S4 screen replaced because it was cracked. Now I'm having trouble with the touch. I can't move apps around in the middle section all the way across the screen. It's also not registering if I press letters in the same region unless I press fairly firm. What What could What could thus be?
A bad touch screen. Get a new one.
You Need New touch screen
,cheap touch screen make you lost more money
Touch screen what? The S4 and all other AMOLEDs don't have seperate touchscreen digitizer. You probably got a big gap between the actual screen and the glass you replaced.
The way to confirm the actual screen is defective you have to remove the glass you replaced and try to touch directly on the screen if it's ok.

They are seperated, they are just glued together and can be separated.

Nope dude. The glued glass on top of the screen is just protective glass. It doesn't work as touchscreen digitizer. Try it yourself, you can touch your screen even when you seperate the glass.

That's just a glass on top of the display man. Do you see any wires or something? I don't. How could it transmit any data about touch then?
The touch digitizer and the screen is both on the display of AMOLEDs. The glass you Crack is just. .. glass
