concave touch screen !

Hi
can anybody tell me how to resolve that problem ??
Unfortunately I had the habbit of keeping my phone in my jeans butt pocket, even when I switched to Diamond touch screened phone I kept doing that, but I realized that the screen got some slight concavity on it that even reflects as irregular pattern of colors seen only when screen switched off or when on but from a sharp viewing angle.
How to correct that ??? any ideas ???
Thanks

Replace the screen.
Change phone carrying habits.
It is a hardware issue, so not easy to fix. Beware that the screen is multi layered (touch screen) so it is possible that any physical shape alterations will seriously change the way it works. It happens that screens go weird when there's dust & debris between screen and the outside body of the phone...

Thanks for your reply
Is it worth it to replace the screen ?? or maybe its better off selling it for less cash then buy another one ?
I have noticed that there is a matrix of visible small dots 2 mm apart from each other, I guess this is the touch-sensing system.

Yeah, the touch-sensitive layer got squished. It should still work fine for now, but over time the touch sensitivity may get worse. The only way to fix it is to get it replaced. If it's still under warranty you should replace it that way, better than selling and buying a completely new Diamond. If not, you can replace it yourself with this: http://mobile.brando.com.hk/prod_detail.php?prod_id=03449&dept_id=088&cat_id=0695

Thanks fhsieh for the info and link.
I will replace it when it fails eventually, now I am releaved and I know that I've got a solution

that's not a problem, when you call goes out not to touch the screen with the ear, is a proximity system and really get away from the phone and lights.

is it under warranty? if it is, u know wat to do!

sorry to revive this thread, but I have the same problem. The problem is only when I'm outside with direct solar light. Inside a room it works well.
I'll try not to touch the screen next time, then post the results here

Already happened to other users, it's an HW problem, warranty repair is the best viable option.

How a small rubber could cause deadlocks...

Basically you're right. The deadlock is caused by the proximity sensor.
There are two possibilities:
1. some circuit could be broken (quite no chance to fix)
2. small grommet inside the display is missing (might be easy to fix)
On my device the little rubber grommet was missing....
Here's what happens inside:
The Milestone uses very comfortable proximity sensor to detect the reflecting light by the users cheek during telephone calls.
This sensor is using an external IR-LED to work properly and to increase sensitivity.
To prevent internal reflection inside the housing there's a small rubber grommet placed between the IR-LED and the sensor.
If this part is missing the internal reflection could cause phantom detection and leads to a deadlock if a call is initated.
@joaelvas: You might check if your device has already been opened.
There should be some sticker on one of the torx-screws at the backside of the case. If the sticker is broken, then your device had already been opened by someone. AFAIK, no warranty in this case.
Anyway you might try to give it to the service
If you're not scared, open the case yourself...
Please be very careful with the damn flex cables... you might ripp them apart so easily.
See here for some instructions how to open the case:

Although it's for the droid, it's the same for milestone.
Good luck,

It's work!!
wow.... amazing, it solved my problem.... thank you so much Bro, u r PRO!!!!

wow, thanks for the tip about the rubber... I was get really annoyed at this cel phone After I replaced the touchscreen.. it would get stuck in calls for a long time. Now a placed a new piece of spounge tape in the back of the sensor and the metal plate in the back of the screen is pressing it hard enough now to block all the side light, it's working as it should.
Thanks.!

my stone,too .
so have to replace the touch screen?it's expensive,
any else??anybody help us!pls!i lov my stone!

Is it possible to get that grommet in India?
Even the official service center don't have that

[Q] Faulty Proximity sensor,is there a way to actually disable it?

Hey guys,sorry for bringing this up.
Whenever i dial,screen goes black and doesn't come back on.
If i place it flat on a table,then it gets lit but as soon as i rotate the device it goes black again.
My HD7 recently started having this problems...
It started happening after i replaced the micro sd inside with a bigger one.
So my concern is that somehow it moved or got dust when i removed the back plastic cover? Where is it placed anyway?
I tried hard resetting 2 times but nothing works. It would be cool if there was a registry or app to take control of it. Can somebody help?
PS. i cannot send it back because i live in Albania (no official htc shops either around here)
Thanks!

Hello,
The proximity sensor is located on the top left of the device, you can see it when viewed under a bright light. Have you applied any screen protectors which can interfere with them? Replacing the sd card should not have any effect on the proximity sensor. When you rotate the device when the call is placed, the screen should go black by default cause of the sensor

@rhn thank you for your reply.
My phone does not have any screen protector or cover of any kind. Also,if i rotate it while in call it still remains black. As soon as i press the call button,screen goes black and wont come back until the call is ended by the person on the other side.
Really really annoying... Oh sometimes it even flashes after the call has ended...

Sounds like a hardware fault ...have you tried updating your rom?You can find a compatible rom in the rom development subforum..

Yep,tried that too. Just updated today and still the same issue.
It also happened after i changed the micro sd,so maybe something has moved in there. There's no other way than try to open the device and check it out,i guess :/
If you can think of something else,let me know

Warranty
Warranty replacement worked for me.
http://forum.xda-developers.com/showthread.php?t=864311

Thanks bofett, i cannot get a replacement. Warranty for this phone was for 5 days!!! (stupid i know....i totally regret picking it up) So that means i'm screwed...
Thank god i still have my great HD2 so i can start opening this phone without fear

Proximity sensor LED NOT blinking in MOTO X

Hey Everyone!
I am new to this site so pl bear with me if I am posting some wrong thing.
Got MOTO X Verizon running on HSPA in INDIA. Everything seemed to work good.
Suddenly after 3 days of normal use (no dropping, no dumping, no water damage), screen started to garble at uneven intervals.
With all the pain to search for the problem all over the internet I at last (i think) solved the problem.
For this I had disassembled the screen and motherboard and just pressed the golden sticker (above the inter-connecting cable on the back of the screen)
Screen works fine now, but I guess I screwed up the proximity sensor mounted on the motherboard (seemingly irreplaceable.)
When calling the screen goes black etc...( i know this issue has been cited many times...mine is different I believe)
This was working when i got the phone (waving my hand always used to start the active display).
I checked my settings for Active display, got numerous apps for the the proximity sensor testing. [ Phone Tester shows proximity FAR and does not change that value whatever i do; "Proximity Sensor Finder" shows 3.0 cm last value and does not change ever either]
Then I tried everything from the rubber gasket installation to a hard reset, factory reset and what not.(thanks to tonnes of websites and people helping all over the world)
NO LUCK!
I also noticed that the LED beside the sensor used to blink which has actually stopped. LIGHT sensor and all others are working nicely.
This is where my issue lies :silly: : " Has anyone got this type of problem? Has the golden sticker on the right top corner on the back of the screen anything to do with the RED LED of the proximity? I tried all dialers, all possible ways to bypass the Proximity but invain. I am not wishing to root this phone and I am not good with coding either. Can this be a software issue? (running 4.4.4).Is there a calibrator out there to rejuvenate my proximity?
PLEASE HELP!!
For the time being I am using bluetooth headsets (where the screen remains open).

In Kitkat?

(waving my hand always used to start the active display).
This feature is gone with Lollipop though...
And I read you're on kitkat, but really there was a LED blinking there???

I own an xt1060. There is an LED there, but its always been less than useless for me. It never turns on. Ever. Not for calls (missed or otherwise), notifications, or charging. I've often wondered why it's there.
I can make it work in Cyanogenmod. Any stock ROM renders it useless.

when you said you checked gasket are you referring to the tinny black rectangle gasket around the led and prox censer? when i first starting working on the x i had smiler issue, the little gasket fell off and i did not notice it

Exactly the same small thing I m taking about.. God knows I dropped it or not... But when I opened it for the 4th tym... I noticed was not there.. Then I did not get it anywhere in sale and so replaced it with a small white rubber piece with 2 similarly cut holes. No luck. Where did u get it from?
BTW I believe it will make the proximity work only if the led on its left side blinks. That works like a transmitter and receive I guess.
My led won't even flash for once..
I plead to all the genius developers to device an app for proximity bypass.

I did replace it with a white rubber gasket almost cut into same pattern after an exhaustive search on internet for its replacement. And I am still stuck.
Also what I believe is that if the LED does not transmit at all, How is it going to help any way?

You seem to not understand that even you have cut a replacement gasket, it may look perfect to you, but it can easily block the proximity and that's about it.
You should try with original one, then start pulling off conclusions if the sensors are defective or not.
Why don't you run a dry test without the gasket?

"Dry test?" can you please elaborate this?
BTW I had tried using without the gasket too. Same values on the tester apps.
If sensor is working each time the value should change at least a bit when open to light without gasket.

By dry test I meant to test it without putting the display/frame over the board and test it that way. If it's not defective you should get proper readings off it.

Correct way to turn off proximity sensor

I'm visiting my parents and my mother's Z3 Compact has issue that screen goes black when call is made. It turned out proximity sensor reports always active on state. It seems to work when I push the top-left part of screen but I have no experience with fixing HW issues so I don't want to open the phone.
Instead I would be happy if it was possible to disable the proximity sensor altogether for now. Phone is bought as used and it seems to have bootloader unlocked so it wouldn't probably be a big deal to root it if that would help with fixing the issue. Any suggestions what to do? I tried some programs like Proximity Screen Off Lite which some people mentioned had done it for them but it seemed not to help me with this issue.

Hi. Proximity issue is result of peeling off screen from frame. Just take some epoxy glue and apply a little to the gab in the corner between frame and screen. Just watch out to not apply glue on proximity sensor, but only on the frame. After that take some clip to press it and left it for 24 hours to make sure glue get dry. Thats all. Of course You can also take apart whole phone and change whole glue adhesive under the screen but this one is quite harder than just apply some glue in gap between screen and frame.
