Galaxy S Proximity Sensor Problems

Hello People,
All of a sudden i am facing a issue with my SGS i9000,
My phone turns the screen OFF when is start a call, Dialing is OK, and the screen goes blank when I hold the phone up to my ear. But at the end of the conversation the screen remains blank, Pressing any buttons wont turn the screen back ON.... after a min or so te screen comes back.. or even when i connect my phone to a charger it works....
what might be the issue? has anyone faced similar problems with their SGS?
I hope there is a solution for this, even the warranty is over for this phone.
any help would be appreciated.
thanks

Have you found a solution? I have the same issue, I don't know if this is a hardware or software problem. I got back to stock rom (froyo JPY) but that didn't solve the problem...

I had the exact same problem and symptoms as you two described a few months ago with my I9000m. So I got fed up and opened it up and found the ribbon cable connecting the speaker and proximity/light sensor partially torn which is why the speaker was working while the proximity/light sensor was not.
You can also try Z-DeviceTest from the market. There's a proximity/light sensor test.
If you've still got a warranty on the thing, I would take it back to shop and have them deal with it. If your warranty is out then you have to do what I did and buy the part and replace it myself.
Here's the good news though. The module itself is pretty cheap at least on ebay.com (search i9000 speaker parts).
I replaced the one on my I9000m and bought another one of these (one to use as spare) because those ribbon cables seem so flimsy (you'll see what I'm talking about if you actually open it up and see for yourself ).

Thanks! I don't have warranty so I've bought it on a Chinese website ~10$ with shipping costs

I have seen this a few times. What appeared to work for me was simply covering the proximity sensors again with my finger for a second, then uncovering again. I say "appeared" as the timing could be a coincidence - but it has happened maybe 3 or 4 times on my phone - and I waited it out the first time, and each of the other times I did the above and it came right back.

Screen dosent work when front facing camera is connected?

Hello again
So i got a i9505 s4 dirt cheap (20euros), the screen was broken, last owner said it stopped working when he tried installing cyanogenmod.
I ordered new screen(original), installed stock rom and it got stuck in sview, i tried everything and nothing worked.
Next i tried rom called aosb (i don't remember if its the correct name, similar to cyanogenmod) it got me to home screen, for 15sec it worked great but then screen went black, phone was still going but everytime i tried to unlock it went black again.
Next i took phone apart, maybe i missed something or frogot to connect, but everything looked good. I googeled for possible problems and found that the proximity sensor(next to the top speaker) maybe broken, disconnected it and still same result. For testing purpose i disconnected front camera and phone worked, but only for 20min when the android tried to update gapps and then i was stuck at not able to unlock again.
Took phone apart third time, cleaned all the contacts etc, installed cyanogenmod and it works, but without front camera.
So my questions are
1. Has anyone ever seen anything like this?
2. Is there a way to use back camera without front one being connected? i can live without front camera
3. Why it goes to sview with stock rom?
Sorry for my english.
I hope somebody can help me.

Well try changing the ear piece module..its something in it maybe.. the proximity sensors are with the earpiece module..
1. Sview random appearances have been noted by many, there must be more to the mystery of this broken S4. A possible magnet sensor error..try disabling it via the xposed modules..anyhow.
2. Well you disconnect the font cam and everything works fine? Eh..never heard something like that..
3. Maybe because of a broken/weird magnetic sensor. As i said..
Plus are you sure without breaking rhe flex you removed and replaced and removed..
Your front cam not working could be because of a bad connection too..
Best is to try *#0*# in the phone menu and try testing the front cam and everything to check whether everything works fine
All the best
Press Thanks if I helped

S4 i9506 both cameras not working (tried everything i could find)

Hello there to all.
I´m newly registered to the forum, although i´ve been using it to search, learn and use roms in my Samsung s3 for some time now.
I´ve bought recently a used S4 i9506. At the time i tested several key points of the device to check if it was all working, however (and don´t ask me why because i cant explain it), i completely forgot to test the cameras.
My problem is the following. Everytime i try to access the camera it says that camera failed or something like server connection failed. I´ve tried every single resolution i could find on the internet and so far all failed to solve it. The problem seems to be in both cameras, i think, because when i try the code *#0*# both Mega cam and front cam give error. Here´s what i tried so far:
- Soft Reset/Hard Reset/factory reset;
- Cleared cache both from boot and manually erasing cache from com.sec.android.gallery3d;
- Tried 3rd party camera apps from GooglePlay;
- Tried the RestartCamera.apk;
- Tried 3 different firmwares for i9506;
- Tried rooting it and then flashed several different roms;
- Switched the rear camera with a new i9506 rear camera module that i bought;
- I cant also test the cameras, because when i use the code *#34971539# they bring a menu on which i can´t use almost every option (see image);
http : / / rghost.net/6Zby4zXFD/image . png
Anyone have any other possible resolution?
I´m thinking on maybe buying a front camera module. Could that do the trick? Could the front facing camera not working properly make the rear camera fail as well?
Thank you for the attention to all who took the time to read.

So far 60 people read and nobody answered. ... is it because you don´t know what else i can do? I´ve been reading the problem may be from the motherboard. What can i do on the motherboard to make things right?
Thanks again

Be patient my friend someone will answer soon

Hi,
I've got the same problem with my s4mini. Both cameras aren't working and all the solutions you explained don't solve it.
I'm thinking about buying another S4mini with broken Display in order to change the motherboard. This might be the only possibility to solve this......

Hey there m8.
I know the feeling, right?!
The thing is that for a faulty i9506 model i could almost buy myself another motherboard and mount it, but i was hoping to find some other solution, maybe even some electronics expert opinion on what i could do in the motherboard to make it work again. There are some videos on youtube that teaches how to change some components on the motherboard to solve problems like dead smartphone or constant auto reboots. Also, finding a faulty i9506 model isn´t as easy as finding a regular S4. :crying:
Thx for sharing the problem and for the opinions,
and greetings from Portugal

Today i've changed the mainboard aaaaaaand -> cameras still not working
So i started to change the front cramera and the ear-brightness-sensor from the old s4 mini with the broken screen into my working one. And now both cameras are working again!:good:
I think the cause is most likely the brightness sensor which is combined with the ear speaker. This could explain why both cameras are not working.
I'm not completely sure due to i changed the front camera also. However changing the main camera did not do anything as mentioned above.
Maybe i should mention: A few weeks ago i've changed the earspeaker-brightness-unit because the speaker wasn't working anymore. Right after this both cameras stopped working.

Thank you for the update on your situation m8. That could be some relevant information there. Can anyone confirm if the sensor is the same for all s4 models? If so i could find more easily one from another s4 model and try it, for the sake of desperation.
cheers

Hall sensor not working.

Hello.
I have thought that Le Pro 3 has a hall sensor. If it does. Mine is not working. I have x720 phone. with 19s version. I don't think is original. It has Google Store and not a single chinese sign or bloatware. I think is a vendor rom.
I tried with a lot of magnets and and there is no hall sensor. I ordered a flip case that was supposed to work with that sensor and open/close phone when you open the cover.
I checked the Accessibility/hall sensor option to On but nothing works.
Did anyone checked his phone for hall sensor?
Thanks

Lastest for x720 is 18s...

Mine eui version is 5.8.019s (Stable)

I testet on my device and there is a Hall sensor and its working well.
I am on the s18 on x720

You have test it with a magnet?
I don't know if mine is not working hardware or maybe is the vendor ROM to blame.
I have installed Sensor Test and at the magnetic field it says uncalibrated. I don't know how to fix it
When I aproach a magnet to the phone in sensor test it detect it and it show it works. So I think is the software to blame.

I tried again with cydras rom. And somehow it works sometime. When I try with a magnet, close to the buttons it works but only sometimes. Not allways.

I received the original flip cover and it works. It must have a special magnet or something.
The phone works and close screen when I flip it.

Camera failed

Hi all, flashed S7 EDGE on U which is 10 the loader, and ceased at once to work that is the camera ( camera failed ) and flashlight is also not working. Put the camera even new and still not working, blinking flashlight works when uvedomlenie.

Not sure what uvedomlenie might be and when you say you [put the camera even new and still not working], I'm assuming that means you installed a new camera? If that is the case it might be a good idea to recheck connections. As I recall, the flex cable for the camera snaps in beneath the motherboard and may be prone to come loose if not careful. I don't think the firmware version flashed has anything to do with camera app issues. It sounds like hardware, and that would be the actual camera.
