[Q] Proximity Sensor Issue? need advice (slight water damage) - T-Mobile Samsung Galaxy S II SGH-T989

Hey guys...I got an incredible deal on a slight water damaged t989 in otherwise great physical shape, and I really like it. The only issue I'm having with it is when I make a call, the screen goes black (still shows the clock at the top...everything else is black), without ever putting the phone to my face. And after that I can't do anything to get it to come back on.
Is it normal for the screen to still show the clock when the phone is up to your ear? I figured it might be based on how amoled screens work (only producing light locally where it needs it), but wasn't sure.
Also, do you think this is the proximity sensor being faulty? That was my guess...it looks like the part costs $23 and is connected to the front camera. I could also try taking it apart and drying it out better (I already did that with the motherboard and it fixed all the other issues it was having, like the main camera not working)...I'm just a little less inclined to do this since I don't see any guides for disassembling that part of the phone and don't want to accidently damage something.
I guess I'm willing to try opening it up further and airing out the proximity sensor...possibly replacing it...but the important question on my mind is does this phone normally still display the time at the top when you hold it up to your ear?

anybody? It would help me just to know if this phones screen goes completely black when making a call, or if it goes black but still shows the very top with the clock and such when the phones proximity sensor is covered up (ie: held up to the ear)

Rainbow marks on screen

I was wondering if anyone can help me fix a problem I've got with my tp2. Basically the device turns on and I can make phone calls and use programs fine. However I can't use the touch screen at all, the hard buttons all work, but touching the screen has no effect.
When the screen is turned off I can see a rainbow pattern on it and it moves to my touch. This could be water damage but I don't remember dropping it in water. The water mark is red on the phone and battery, so it probably is water damage.
Just wondering if anyone knows an easy fix for this. Thanks for reading
Just had exactly the same thing happen this week. At first if I turned it off and firmly pressed my thumbs up the screen (as if I was pushing the rainbow marks to the edge of the screen) I could get it to respond for a while. Then it started to get larger spots and now I can't get it to respond no matter what I do...
If the touch screen is not functional, then you'll likely need to replace the digitizer. I would suggest purchasing the LCD/digitizer combos, as they are easier to install for first timers.

Slightly broken Xperia Play, help?

So I bought a brand new Xperia Play from eBay. I assume that it is covered under warranty.
However, the other week I dropped the phone. The LCD Screen is not completely cracked! What is disgraceful is that the drop was not even from a high height! Such a brittle piece of plastic!!
The strange thing is, although the phone still works, it seems to run a little bit more sluggish. I'm not sure. The BIG problem is, when I begin a call, my screen turns black, and once the call is finished, the screen won't turn back on again (Even though I can hear sounds through the speakers). If I press the lock button quick enough before ending a call the screen sometimes turns back on.
I was thinking about buying a new LCD screen from ebay for £20, however I'm afraid that it won't fix the 'screen turning off during a call' problem.
What would be the best way to get this phone repaired?
Any help would be much appreciated, thanks.

Maybe you damaged the light sensor on the screen?

Maybe you damaged the proximity sensor?
If the proximity or light sensor was damaged, how would this make the screen switch off during a call, not turning on again?
Does anyone know the best route to get this repaired?

Replace the front glass. Maybe you didn't destroy the proximity, but just damaged it to behave in that way. Also, broken glass is also maybe affecting it.
Thanks, I'm going to buy a new screen then. God knows how long it will take to ship, but I will keep you guys updated with pictures as soon as progress is made.
Mine was doing exactly the same thing after shattering the glass. The proximity sensor could not see through the cracks and the IR light would refract back in as if it were against my face. It behaved strangely where sometimes opening the slider would snap it out and other times it would not. Replacing the glass/digitizer did the trick. The only problem was that no replacement parts on eBay include the adhesive gasket and the old one is likely ruined with stuck-on glass shards. I pulled off as much as I could and reused it but me touchscreen doesn't stick all the way down sometimes. I ordered a dummy phone to see if I could salvage it from one.

The screen is designed to switch off during a call if it detects you face next to the screen (proximity sensor) if it is damaged and reporting wrong info to android. That is why the screen switches off during call.

The sensor is fine. The glass covering it is not.

[URGENT]Screen!

I've broken my screen, to be accurate not me but some dude, he paid for the new screen. Ofcourse, he picked the most ****ty store he could to fix it to pay less money for it, it was horrible. Light from the side of the phone was leaking, the buttons didn't light up well, the front camera lense was missing and most importantly the screen itself wasn't like before. First of all, it fell off from the phone all the time ( with just the two connectors connected ), it was horrible pale and etc.
Being the social akward I am, I was silent about it, and got used to the screen after I glued it.
Anywho, yesterday without any warning or anything screen stopped working. Sound is playing, digitizer is prolly working, screen? nah. Black screen. I opened it up few times before as the LCD connector disconnected, it was okay. Now the connector was inside still, connected and I opened it and tried to tighten it up, thought it was loose or something. Nope, still no screen.
Now I come to you, xda, with the need of help.
Where can I buy a REAL. LCD2, like stock screen?
And if its possible, how can I identify if the screen I got earlier IS lcd2 original screen? ( the seller said it was, obviously it wasn't )
Thanks! ( Really hope for fast answer )

Proximity sensor problem (SMMI test fail)

Hi, I've searched this forum and the Internet in general about proximity sensor problems but it seems like basically every problem that someone else had was fixed by removing tempered glass/screen protectors/cases/covers. I'm having a proximity sensor issue and I'm not using any screen protector or case.
This has happened twice now. Once when I was listening to visual voicemail, once when I was making a call. The screen goes dark and will not respond to any wake commands. Every now and then it will turn on for half a second when I hit the power button but then turns back off again. The first time when I was listening to visual voicemail, I had to hard restart the phone by holding volume up and power. The second time during the call, I managed to hang up the call in the half second the screen came back on, which ended the problem.
Right after that, I tested the proximity sensor using the SMMI test (calculator .12345+=). The test makes you put your hand near the sensor, then away, then near again. During the test, the phone immediately sensed my hand near the sensor except that my hand was nowhere near the sensor and there was nothing else near the sensor either.
I did a reboot and ran the test again. This time, the test finished correctly. The phone did not detect my hand until I actually put it near the sensor.
I'm running stock everything except I do have root(ZE551ML). I'm leaning towards this being a hardware problem and I've only had the phone for a week so I'm well within my replace period with Amazon. Is there a solution to this I'm missing or should I just replace? I'm a firm believer in troubleshooting first. Plus, setting up the phone the way I like again will be a huge PITA.
Thanks.
I would replace. It does sound like a hardware issue, and your better off getting a replacement instead of a possible pain for the life of your phone.
I get the same, and the flickering screen happened once to me after I I have just put a tempered glas protector on it ... removed it and so far no problems, but who knows.
I think the SMMI test works correctly the first time you start it, and incorrectly the 2nd, 3rd etc ... dont think it is a hardware error ...
Hi all, i have a zen2 with this same problem, i think doing sensor calibration can resolve the issue... but i can´t found how to do, by code, or by app...
Any body know how to do calibration of sensor aproximty?
Thanks in advanced!
Ps. I dont have screen os glass protector...
i don't having tempered glass or any screen protector. my proximity sensor is not working. Even i checked .12345+= but it gives error in proximity sensor. what to do? plz anyone?
same problem
Hi to everyone,
I have the same problem with the proximity sensor.
After a device reboot, the simmi test work correctly, but after some hours the test fails.
Someone know as I can calibrate the sensor ??
Thanks
I just fixed mine, cause I was having that issue for a LONG time now.
I actually just stuck a piece of paper in front of the light sensor part of the sensor window on the screen. It's the right side of the sensor window.
To be more clear, a while back my screen broke, so I ordered a screen online and changed it. Ever since then my prox. sensor didn't work, so I couldn't use the keypad during calls (the screen would go black).
My screen still isn't attached properly, so it's just being held in by the floppy protective case I have on it right now. This allowed me to pull the screen away from the phone a bit and slide a piece of paper behind it right in front of the light sensor. As soon as I blocked the light sensor then the proximity sensor started reading properly.
I got the idea because I was trying to clean the screen, thinking that it might just be dust blocking it or something. That didn't help, so I tried cleaning the sensor, but had the calibration test running at the time, and it instantly worked!
So I kept playing around with it and noticed that every time I blocked the right side of the sensor, it worked, but as soon as I removed the brush I was using to clean, it stopped working.
I stuck a piece of paper in, and BOOM, worked just fine.
People might want to build on this and maybe try sticking a piece of tape over the right part of the sensor. I haven't tried it, and since I finally have it working now, I really don't want to play with it too much and mess it up.
Hope this helps anyone else having this issue.
Hi all,
I am using zenfone 2 laser z550kl. Screen blackout during call and did not come up till the call is cut. I changed only the cover of proximity sensor and phone is working fine. Change the small rubber covering of sensor and it will work.
Hope this will help all if still using asus phone.

Can I re-glue my screen?

I have a n910a (AT&T) variant Note 4 that I bought off of eBay, and the screen does not seem to be attached correctly. The proximity sensor reads extremely high in normal operation (causing all kinds of pocket dials, app launches, etc), but when the top left and right of the screen is pushed in 1-2 mm, it reads normal.
This makes me think I have a phone that have a phone that had a ****ty screen replacement done on it. The front camera also gets liquid in it if I spray cleaner on the screen.
Is it possible to re-glue the screen? Would I have to take the phone all apart, or could I use something like a syringe filled with glue? What kind of glue?
I'm scared of gluing over some kind of important sensor, and ruining the phone's operation.
Any ideas?
Looks like it's already ruined to me
