[Galaxy S I9000 Q&A, Help & Troubleshooting] DerBobo:
Hello Guys,

a Friend bought a used i9000 on ebay for 130€ from a business man, which got a ne phone from his company and sold hin mobile on ebay and he asked me for a litte work around of his "new" phone.

Optically is the phone perfect BUT if I take a call on Android 2.3.6 display stays black (with backlight) and I can make the call. But I can't do anything more, hang up etc. If the opponent hangs up, I hear the hang up sound but display stays black and thephone wount do anything. So it's needet to pull battery, put it back and restart the phone. On doing a call, the phone has similar problems, it freezes.

After a couple of re-flashes with odin nothing changed.

So I tryed to switch to actual android OS. I flashed SlimBean 2.7. Every thing workes well. but even call-issues. If i receive a call, the phone woun't do anythin and it keeps ringing and "holds" the call for exactly 32 seconds. Now I can talk with the caller. But most callers don't wait 32 seconds to call to me :) If I do a call in JB I can talk from the first second on, but display freezes and I can't hang up. Thats the state for around 28 seconds and then phone will response normally and I can hang on and do everything I whant.

Even in Slim I tryed reflash a fiew times with no cahnge.

Has anyone an idea?

I think thats a hardware related problem. But in fact its possible to do a call, but only with that issues/delays. So I need a solution, that JB (SlimBean 2.7) don't "hold" the call/freezes for 32 seconds. I think because its every time 32 seconds, thats a fix value in JB. so I need something to cahnge the value from 32 secs to may be 0 oder maximum 5. But thats only guessed by me :) so I need help of a PRO here to solve that nerving issue.

I also tryed to install other dialers, but thats not a good solution, because the use for calling the stock rom dialer (phone.apk), damn :)

Please help me guys :) (sorry for my bad english ;) )

UPDATE: I did read a litte in web and found, that the light sensor could cause issues in calling (start and end). So I downloaded a app whitch will show me he values of the light sensor. Ands its true, the sensor will show me whole time same values. I changed the sensor od the device of my friend and mine but that does not solve the problem. same issue.

In second Post I'll load a some Pictures of both devices up. My device shows around 30 lux and the one of my friend around 5.

UPDATE 2: After some more reading in web I found more guys with same call problem but no solution. May be it could help to disable GP2A Driver oder better only to overwrite the lightsensor value with a fix one.

UPDATE 3: OK I tested with 3 apps and the proximity sensor of the phone is broken ...now i need a solution to disable it or set a fix value in android so that the sensor is unused.

Any ideas?

UPDATE 4: I downloaded the "Hardware Disable" app from Play store and disabled GP2A.

It works for now, I just have to switch off the screen manually by pushing power button at a call and turn it on by pushing power again. But thats no problem for me anf my friend and much better as the call related freezes.

But I need at every startup to confirm to disable the sensor. So I'm looking for a permanent solution for this. Also because the device feels a little bit laggy now.
