[Q] calling freeze

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.

SOLUTION
So Guys I found a good working solution fpr proximity sensor delay, 32 second freeze by taking a call.
I wrote my Solution in SlimBean thread
http://forum.xda-developers.com/showpost.php?p=32809014&postcount=4406
Schould work on any ROM (GB, ICS and JB) because they all use the same Hardware .so (sensors.aries.so in this case)

Click to expand...
Click to collapse
You might have lost your APN during the flash - to check this go to Settings-More-Mobile Networks-Access point names if that is blank then you have lost your APN and have to manually put it in - left click the button to the left of home screen button and reset to default. If that doesn't work hopefully you did a backup and you can reflash that and then the rom you want. Hope that helps.

Signal Bounce

Have moto x 2014 for about a week and I'm noticing that the cell phone signal sometimes drops to nothing and calls go straight to vm. Other times I attempt to make a call and I notice almost no signal so call doesn't complete. Since didn't happen with moto x 2013. I've had to constantly go in and out of airplane mode to resolve issue.
Anybody else notice this?

Call drops as soon as new call comes in

I'm having a problem with my phone, probably 80% of the time, where whenever I receive a phone call while on a current call, the phone will end the first call and allow me to hang up or answer the second call. This is extremely frustrating as I work from my phone and speak at least 5,000 minutes a month if not more.
The phone is completely stock, call waiting is enabled on stock settings, I have disabled wifi calling, and I have at least 3 bars of LTE or HSPA+ when this occurs. I got a new sim card when I got the phone too so I don't believe that to be the problem. I am not sure why it happens sometimes and not others, but I am desperately needing a solution. Being on hold for thirty minutes with a utility company is bad enough, imagine waiting 30 minutes just to be cut off by another call less than a minute in.
Also, while I am here, I am noticing that touch sensitivity is significantly lower than it was on my s5. It's taking me sometimes two or three touches for it to register. Are there any hidden settings that could increase touch sensitivity? I am not against having to root to improve any of these two things.
Thanks

Nokia 8 Sirocco dropping calls after Android Pie Update

So I got the Android Pie update in Dubai a few days ago. then I did a factory reset as I like to have a fresh clean start with a new OS. Setup everything but now I noticed on 2 different occasions when I am in the middle of a phone call, I would stop hearing anything nor does the other part hear me. I'd then have to call them again and the call is back to normal for a couple of minutes then gets muted automatically. A restart fixes this sometimes but it's very annoying. Anyone else getting this?
i have a nokia 7 plus and after the pie update i noticed that some calls just end out of the blue. It can be 10 seconds into the conversation or 5 minutes. I cant see a pattern that would cause this. I once tried to call my GSM operators call center, it took me 7 attempts until i could finish my request. each time waiting 3-4 minutes to talk to somebody. Really annoying.
I had a simillar issue with a nokia 7 plus. After a carrier service update on the playstore, the issue disapeard.
No issue with my Sirocco, but i buyed it after the carrier update.
