Screen going black when calling.. - Xperia Z3 Compact Q&A, Help & Troubleshooting

I have installed Xposed and Sensor Disabler and have disabled the proximity sensor since I was guessing that it was that causing the error. But screen still goes black the second I call and stays black. Only way I can get it on is if called person hangs up or if I double tap the screen on button many times and then if I'm very lucky the screen turns on but easily turns black again very quickly.. What am I missing here?

old issue. Look for proximity sensor issue / failure. Happens with aftermarket screens, but also because of the ****ty sandwhich construction of the phone. There is about one mm friction possible for the frame, which leads to the slowly letting loose of the screen. Have a Z3 compact like that. tried glueing (B 7000 glue) but still. I can see the light inbetween frame and screen. Only a hardcover can possibly maybe prevent this screen from dis-attaching itsself from the frame. I rooted mine as to try disabling the proximity sensor, but I also failed doing that. I actually bought a Z1 compact again. Easy to fix. Thats why I thought the Z3 compact would be an upgrade. Well its not. Its build-quality is a nightmare. And repair also sucks. I even bought a screen plus frame new, and after installation I already saw space between the frame and the screen. Can't sell mine. Its useless. Stay away from this model. very, very bad.

screen defect?

I just got a tilt about a week ago and ive noticed that in the middle of the screen there seems to be a purple greenish tint when put against incandescent light. The size of said glint varies in size but i'm unable to see what changes the size. Not sure if its heat or pressure or something. The touch screen works perfectly its just really annoying to always see such an annoying glint.
An interesting discovery is that when i press all four corners of the screen it disappears and when i press in the middle of the little square it seems to spread out. I feel like theres some kind of material or something in the touch screen that is causing this due to pressure. I keep it in a hard case in my pocket so the screen isnt pressed on inadvertently.
I've searched the forum for any answers but i havent seen anything about it. Any response or help would be greatly appreciated. I'll try to get a picture of it up asap but i left my camera at a friends house and dont know when im getting it back...thanks in advanced

Do you see the same "annoying glint" under neon light (not day / sunlight)?
Lots of NOKIA and SONY ERICSSON phones for example get this screen recolorization under direct sunlight - this has nothing to do with the screen being defective but with the plastic above the screen which breaks the light and shows you this colored spots. If you can't see the same spot under direct neon light then this might be the cause.
It is normal that you get color changes while pressing the screen in. First of, you press / bent the protecting plastic and the liquid within the screen which causes the incoming light to break in a different angle, therefore the color changes. (BTW: you shouldn't do that too often, it can cause permanent stains on your screen!).
There sure is the possibility that your screen gets pressure from underneath due bad assembling! If you're still under warranty, try to get a replacement.
yeah you cant see it in day light. but i feel as though there is constant pressure on the screen between the plastic and liquid since the spot is always there and doesnt really go away (unless of course in daylight).
well im thinking im going to go back for a replacement. thanks for the quick answer!

Ghost touch after screen replacement

Hello folks, i replaced my screen on Z1 (third time now....). And I have one issue. When I use this aftermarket one, after a moment of usage it starts to touch itself.
Usually in the middle of the screen, and keeps touching everything that is in the middle. Sometimes I can make it stop by turning the screen off and on.
What I think I did is, that I somehow removed some electrical tape from somewhere in the phone. Do you have any ideas where should I look?
It is pretty annoying thing.

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.

Xperia Z3 Compact Screen Flickering at Random

I have a D5803 that came back from being serviced. The touchscreen went bad, so the whole assembly (screen + sensor) was replaced.
Since you have to almost completely disassembly the phone to get to the screen, I suspect something went wrong during the repair.
The screen is flickering at random. By flickering, imagine a bad fluorescent lamp: you can clearly see the brightness varying vary fast, causing a flicker effect. Also, imagina a CRT screen. The flicker stops when you refresh the screen, like cycling through the home screens of your phone.
The guy who repaired it said it is a bad resistor that controls the current going to the panel's backlight. His excuse is that the board is very thin and fragile and that something might happened during the repair service. He also said that if he tries to do something else, the problem might get worse/something else might break. I suspect the screen installed is not OEM and is of bad quality. Sometimes the screen keeps autopressing as if someone was actually touching the screen, but not. Wiping the screen down on soft clothes (cleaning it) solves the problem. The screen probably doesn't have an oleophobic coating.
So, my question is: Is this guy right or is he lying (trying to push me ****ty parts/service)? How to know?
Also, is it possible to have a slightly smaller sized screen part? Because it feels that the screen area has decreased a bit (bezel increased somewhat). But since I do not use this phone since almost two years ago, I might be imagining things.

Screen won't show after cracking the screen

So my phone cracked up today(rip) while I was doing some gym exercises. The phone fell from like 1.5 metter or so and the screen cracked.
The problem is that screen won't turn on, even when the phone looks like it works. I tried to furce shut down and turn it on and back and recents buttons work, but screen while stay black. What should I do? I will replace the screen but I'm not sure why screen won't show up, maybe something got disconected with the fell? Does anyone has any type of experience with this?

So, your screen is broken, and you need to have it repaired, what is the problem? Some parts still working?
Just get it fixed...

I really don't know why you asked this question, but I always try to be helpful. Since you did drop it, and from such a height (do you like keep your phone in your pocket while doing pull-ups? Mine's always in my bag and I use BT earphones).
Since your screen is cracked, and that impact could've damaged your phone in many ways.
1. You could've damaged your digitizer, which is a screen replacement situation
2. You bent a cable from your screen to something else, and that may be the issue, still would need to replace the screen.
Your buttons working have no relativity with the screen not working, it works with other hardware not interacting with your screen.
Don't go for third-party screen replacements that "fixes your digitizer seperate from the touch", it mostly doesn't work, and it'll be a waste of money, if you bought it from OP Store, just RMA it, or if you bought it from a seller in your country, just order the screen off eBay, and have it fixed. Your shop will most likely replace it with a non original screen, which will be horrible.
Cheers!
I think he is confused about the glass versus the AMOLED panel. A lot of times, you see folks with broken glass, but the screen still works (still displays graphics) and he is wondering why that isn't the case. At least, that is how I'm interpreting the question.
The answer is that the "screen" is composed of layers. The top layer is the glass (which for Super AMOLED also incorporates the touch panel or digitizer) and below that is the AMOLED which actually displays the graphics.
Since the glass is broken, and the AMOLED is not working, it's possible (or even likely) that the AMOLED was also broken in the impact. Yes, it's also possible that a connector has come loose. But from what I'm reading, it's actually common for the AMOLED to break before Gorilla Glass does: http://www.gophermods.com/amoled-vs-lcd-tale-two-screens/
A lot of times when you see folks with glass broken, but everything (touch and graphics) still work, it may be with LCD screens; which are supposedly more durable (more possible for glass to break before the LCD).
