Lumia 950 - not working proximity sensor after falling - Windows 10 Mobile

A week ago, my lumia 950 passed the hard landing on the asphalt. The effect was that the right bottom of the screen was firmly crushed. Quickly protective has not even been violated, the impact went centrally in the corner of the screen. Phone after this event, works normally: 100% efficient display, touch also. But the problem appeared during a ringing, after pressing the Call or Receive buttons, the screen immediately goes out. Additionally does not work on the screen when I cover the proximity sensor and when I turn off the screen, "Summary Screen" should appear on it; Time and notification, but nothing but a black screen. At first I thought that the guilty of this state is a cracked screen, but when I ordered a new one, the problem did not disappear. Then I replaced the whole ribbon with sensors I bought but it did not do anything. So it remained to restart the phone, which also did not help. Interestingly, after reboot, as I turned off the screen using the side button, you could see a summary screen for a second, but then I have not seen it anymore. I know that Era Lumia is a story but maybe someone once met with such a problem.

[Q] What do I need?

Ok, so I didn't know that, that (from my other post) was "Insurance fraud". So I decided to fix the phone myself, Insurance cancelled. Now as you may already know, I stood on my phone. I am guessing that the Digitizer is the touch panel and the screen is a the botton displaying the image.. Once the damage was done, I quickly checked if the phone was alright so I pressed the "Unlock key" and had to swipe the unlock screen to see if the phone was working, so obviously the Digitizer is working as it did change to homescreen when I swiped the screen.
As I panicked I took the battery out, and turning the phone back on hoping it will work, It did not. Some green dots and lines started apearing. Then it stopped displaying, so a black screen after the vibration when I'm turning on the phone.
I also know that the phone is still working because when I plug it into my computer Windows 7 has that little bleep..
The glass screen is not cracked but, when you look at the screen at an angle you see the some scratches (or cracks) underneath on the AMOLED..
Now, my question is, do I need a new AMOLED or a new Digitizer?
thanks for your time!
edit; I've been looking at abit of nexus one Screens/Digitizer's, they seem cheaper, so would they work with a Desire?

[Q] Touch screen doesn't respond to touch

My S3 has been working fine for months sort of. I bought it off of ebay with a huge crack in the glass, then my brother dropped it and all the glass fell out. To use the phone we has to touch the bare LCD of the phone, which after a while we just but a screen cover over it. I waited 2 months, bought a new glass replacement and put it on, everything worked just fine. After a little the home button when pressed to the left a little would make the screen go crazy. it would start tapping and swiping in random places. After locking and waking the screen the phone was normal again. after that, i removed the glass again, and this time when putting it back on if i pushed the home button it pushed the glass down a little, which would turn my screen black. locking the phone and waking the screen again turned the screen back on. Also the screen was a lot less sensitive, i'd have to tap a key 2-5 times sometimes to hit a specific letter. whenever that happened i put 3 dsi's to weigh it down and push the screen down, which would improve the sensitivity. that worked twice, and now my screen doesn't respond to touch at all. the screen will wake, but only when i press on the bottom right corner of the screen will it respond to touch. Any word on what could be the problem? i need to know what to buy to replace in the phone. I've already taken the whole phone apart and plugged everything back in, after i had tried everything to get my phone to respond. Could this be a digitizer problem, or an LCD problem? any possible fixes without having to replace anything?
The first issue was using the device without the glass installed. By touching the bare LCD you most likely damaged it. Your best bet at this point is probably going to be to replace the Touch assembly ( Glass / LCD Touch digitizer ) . Also keep in mind, when doing any sort of Screen replacement. Be sure to keep everything as clean, and dust free as possible.

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 canĀ“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.

Top of screen unresponsive

Had my LG G3 for just over a year, dropped it a few times but nothing major - Screen/casing is in perfect condition still.
The screen has started to raise up so light bleeds out on both sides, tried to press it back down but unfortunately it springs back up. This didn't really bother me until the top part of my screen became unresponsive, I can no longer pull the notification drawer down- I've turned on the show touches in developer options and the screen doesn't pick up my touch at the top of the screen, if I put it in landscape mode the same part of the screen is unresponsive.
My device is under warranty but I'd rather find a solution myself to avoid being without a phone for a few weeks etc.
Is there anything I can do except replace the digitizer?
Curtis
Bump. Having the same exact issue & can't find any solution.
Well, mine had the same problem of the digitizer raised up... I discovered that my battery was swollen then I replaced it with a new one and it fixed that problem... No idea about unresponsiveness...

Proximity sensor is always on after screen replacement

My screen was broken and ordered a new one from aliexpress.
I'd replaced it by myself and absolutely satisfied with it: more then enough brightness level, good sensitivity
My proximity sensor is always on regarding to service menu and built-in diagnostic app. When I place or receive call screen goes black and only sometimes it is possible to turn it back by power button. No red light in up left corner.
And only once, when I blew to usb port by my mouth with all my power it worked for 5 mins. It is not a good idea cause there are a lot of moist in my breath and screen went "un-glue" in bottom right corner.
BTW what is the best way to glue screen with both-side-sticker. It seems not durable and one corner of screen is a little bit up. But I have two more stickers.
PS rooted stock without any exposed or gravity-like apps.
Thanks.
