Faulty proximity sensor galaxy s gti9000

Does anyone know of a way to remove the proximity sensor drivers or shut it off completely my screen just goes black during a call and i need to use the keypad during calls i have tried all the proximity apps on market and it has no effect, have tried calibration etc odin firmware updates to the point i killed my phone just got it back from repair and was told it needs a new chip to rectify the problem.
I have spent weeks going through forums for a solution and i know on my brothers sgs 2 it has a setting in the menu to turn it off.
This seems to be a common problem with no resolve so im looking for someone to resolve this problem and make alot of people happy.
We all no As these phones age this will be more and more common.
Techies get ur teeth into this or even software writers make An app n earn some cash,
This would b a great ego booster for someone to say i solved that when no one in the world could.
Thanks...........looney

Mh? Why not pressing the home button during call.
Screen is enabled then...
Anyway MIUI got this option to switch it off.
Don't know if this setting is available in Stock ROMs.

screen should go back on when you move your head out of the ~5cm sensor radious. if it is not happening there are two possibilities:
- something wrong with firmware -> reflash phone with pure unrooted samsung firmware and check if problem persist
- someting is wrong with proximity sensor -> use warranty and send it to service center with proper description of the problem

Thanks for the replys the home button won't work as the proxy is up the spout had it checked the chip is blown, when u press the home key won't work as the phone is trying to find the proxy then eventualy it will crash and force close.
No software update will do it as its a hardware fault unless it turns it off so will have a look at the one you suggested.
There is def a stock version but i fear it is only on the s2 to turn blank screen off il check my bro's firmware, till then keep the suggestions coming in thanks....

Here is a possible solution. Check the + 3.7 volts at this point, if there is no tension, then feed it thither with a jumper

Thanks for the tip. Where can i get 3.7 V from? (which part of the MB)? Is there a way of hardware disabling the sensor? the software testers report 0.7 mA leakage on a sensor (which is faulty anyways)

[Q] Proximity and the ambiant light sensor doesn't work

does anyone experience proximity and ambiant light sensor issues mines wont work. first i thought it was broken and bought a new sensor replaced it and it still wont work. the headphone jack and speaker works ok but not the sensors anyone? I also tried the sensor reading apps to see if its working. proximity wont show anything and the light sensor gives me between 4700-5000 lux but wont change no matter what light condition any help i cant even make a phone call without headphones anymore

What kind of rom are you running?
If you replaced it then its not a hardware issue it software then

well ı've been using pa v2.54 before and flashed lots of roms in this 3 months i even flashed official rom went stock but still no luck :/

Really strange even with a new sensor and stock rom isnt working maybe the socket isnt good maybe a problem with the motherboard i dont know i thought it might have been a rom problem maybe the people here had a similar issue and they might help i wish you luck and i hope you find a fix

thanks if it was due to the socket im guessing that the speaker and the headphone jack would also not respond... but yeah its a minor issue but really annoying

So I realized if I unplug the sensors the reading will still continue bounce between 4500-5000 lux so im guessing its not an issue of the sensor itself there should be something else... Right?.. Please back me up can be it be caused by the drivers of the sensors ?

And i found this (last post) http://forum.xda-developers.com/showthread.php?t=1446005&nocache=1

Yes that picture in the last post could be it it could be a motherboard problem like that just be careful if you dont know what your doing

Sony has an app on the play store called Xperia Diagnostics. Download that and try the proximity sensor test. If it doesn't work then it's likely hardware and you should take it to a service center for replacement

I had the same problem with the screen staying active during calls but after a reboot it was fixed. For the proximity sensor, go Service menu by dialing this *#*#7378423#*#* kai calibrate it and check if that fixes it.

Broke my screen, camera stopped working, vibrates randomly

I broke my screen last week , it fell and was damaged, and the camera stopped working too. I fixed the screen, but the camera is still offline, tried to change the rom, but no changes., i am getting the "Error, camera not available". When i click on camera icon, it shows a black screen after some delay and then right away an error message pops up with "Error! Camera not available". When i load this from any application, such as snapchat or instagram, it crashes the application. Has anyone dealt with such issue before? Give me some hope, what could be wrong.
The camera was not working even before i replaced the screen. (The screen repair was good, i made sure nothing was touched that should'nt be touched.
The phone's proximity sensor seems to be a bit off too, the phone also vibrates ( like it received a text message) randomly.
Unrelated issue: the screen i install has a round ring that appears if i press the screen to hard at a certain spot. it's not too annoying but it is there.

Broken flat cable, broken camera. Physical damage.

Well i didnt opet Z1 before, so i dont know if you can only replace flat cable (if that is problem) or you must replace whole camera module.
Best bet is to give to service center, probably they will put new module on it, and its best in my opinion.

Most likely put a new module in there as the modules are machine made are probably solid.

Status Update
So i opened the phone again, and seems like i was able to fix the screen issue.
Issue of camera remains. I removed the camera from the socket, and disconnected its wire from the motherboard. When i accessed camera without wire connected, it straigth away went to "ERROR. Camera not available. Earlier, when wire was connected, it took about 5 seconds and then outputted the Error. Flash/ Front camera are still not accessible or usable even when front camera was plugged out.
Weird vibrations are felt randomly, i am still trying to pinpoint what causes them, but they have decreased significantly.
My question now is, will replacing the camera fix the camera issue? Or is there a deeper wire/motherboard issue here? What would be your next step to investigate it further. Also, can this be not a broken screen issue but a camera issue covered in warrantly?
Additional info: i have tried reinstalling ROM, flashed T-mobile's original ftf file, cleared camera cache, files etc. used 3rd party apps but no success.
#####SOLVED: SCREEN HAS WEIRD FLOATIES WHEN WE TOUCH AREA NEAR THEM
This is caused because of dust between the digitizer and the back of the phone. To fix this, simply open the phone up and remove any dust particles between the digitizer and the phone. Screen will work perfectly after that.

When you say module? you mean the camera with the connection wire ? or something more than that?

The camera with connection wire

Update: so bluetooth call recieving does not work, people call me, and if i pick it up, voice does not work over bluetooth anymore. music skips randomly too. My question was that will camera module replacement fix this? or is this a deeper issue, such as cable that connects the camera module? what will i need to replace .

I don't think that anybody here could answer your questions. You should take your phone tot a service center.

SOLVED it.
Fixed it! The issue was that the back camera module was malfunctioning. Because of that, phone chip that controls camera (also controls vibrations) was not functioning properly. I bought a used camera module from ebay, plugged it in and phone works perfectly now
Feel free to pm me if anyone else has questions about this, or need help dismantling phone. Xperia Z1s I AM BACK!!!

[Q] problem with compass and gyroscope

Hello,
After replacing the screen of my xperia Z1 in a mobile store,the Z1 doesn’t find the compass hardware and the gyroscope doesn’t work yet. Is their a cable missed or some hardware is breackdown?
Thank you for help

I have also had same problem after my lcd change. I have solved my problem. Can you check and tell all the sensors are not working or only the compass and gyroscope.

After having my lcd replaced I noticed my sensors stopped working. Well actually compass has stopped working completely but gyroscope, accelerometer, proximity, and light sensor sometimes stop working, and after a reboot sometimes they work for some time.
Also I noticed that in antutu benchmark app it says not supported for not working sensors, except for once when it showed me the right model for the magnetometer.
It'd be very helpful if you told us what you did so we can try the same

I also had the same problem which you described. In my case compass was the main problem. In my case Compass won't show any reading and other sensors will also stop working once I checked the compass.
The compass was in the main flux cable. Once I have replaced the cable my compass and others sensors also started fine. I suggest you to replace the main flux cable.

Hello,
Thank you very much for your answers.
The main cable has dimension of the Xperia Z1 ?
The cable picture in ebay store :

Thanx

Yes that was the cable. Compass present on the opposite side of the keys area. You need to change the cable.
