Apps Sound is off during call

Dear all (hoping that Jocala reads this),

I would really appreciate some help with an issue I am having with my Android phone.

I have a Samsung Exhibit II, rooted and unlocked. Since I bought it I have been having a most distressing issue:

Sometimes I try to make a phone call and the sound is completely turned off (on both ends of the call). The other side cannot hear me, and I cannot hear them. I can see the time running, the call is connected (I can see that even through the other device), but there is no sound on both ends, regardless of what is the other phone (mobile or land line).

To help cutting to the chase:

1. No, I am not pressing mute or add call with my face.
2. It does not help at all to press speaker phone, mute, or any other button while on call.
3. No, I do not plug in headsets or headphones prior to calls, nor at any other given time. Since I got the phone about 2 months ago, I only plugged the headphones once.
4. Yes, it does take sometimes 2 or 3 reboots so that the problem goes away. But the problem does return very often. At least once a day now.
5. Restoring phone to stock did not work at all.
6. The issue is also not related to my ROM, as I already installed different ROMs (currently, I have PeachSunrise, but I am using Go Launcher Ex on top of it). I already used, with the same effect, the stock ROM, Go Launcher Ex after rooting over stock ROM, and now Go Launcher Ex on top of PeachSunrise.
7. I uninstalled all active programs (and their related services and processes, which were Lookout and Easy Battery Saver).
8. I even tried replacing some files to see if I could have the problem solved, but nothing changed at all. And, since I am not very savvy at these things, I tried replacing what I personally thought could be linked to the problem. These were:
a) phone.apk
b) contacts.apk
c) contactsprovider.apk
d) Phone_Util.apk
e) PhoneCrashNotifier.apk
f) PhoneErrService.apk
g) SpeechRecorder.apk

9. I am living in Brazil, and had the phone for about 2 months. I cannot return it since I am here, and the phone is not stock anymore (bought it at Walmart).


I would REALLY appreciate any help on this. I am very much disappointed at this point, and I already lost so much time trying to deal with it. But I will not quit.


I first posted this on Exhibit II thread. Please, see also:

The following is my alogcat log, which I produced by turning the program on, making a failed call, and then turning it off again:

Since your problem persists when restoring your phone or even change rom, this sounds like a hardware problem. I know you said you have rooted it, but it seems like the only solution is to get it fixed or replaced.
 
Thank you for your answer miXer.

If the problem seems to be hardware - since it occurs with different ROMs - what I can't understand is why the phone works as often as it does not.

Also,what puzzles me is that throughout the internet you find many people reporting what seems to be the same problem as I reported here, but on random different phone models from different brands.

Again, my biggest problem is that I am not sure that Samsung is going to have it back and send me another one to Brazil (as I understood, this phone is being sold just ion the USA)...
