[Galaxy Note II Android Development] universil:
I have to say. that the adaway reason seemed to be sure for most of last night, but since then, I have wiped all the wipes and internal storage,put in rom from scratch,and downloaded my apps from google play, (not using any backups from titanium), and still after a reboot it done it again.Cant hear the person at other end, and not even the ringtone if I call them.

kernels, apps,rom's, nothing seems to fix it.

I am going to try an old rom, using same tactics as above and see what happens.

If I find an answer I will let it be known.

Latest thing I have been trying is switching off usb debugging!

It seems to almost always stop hearing caller when it has been switched off and charged.I tried a couple of times switching off, charging, with usb debugging disabled, and so far so good.Anyone think that might have something to do with it?

EDIT WITH DEFINITIVE SOLUTION

Well I suppose I was bound to find out the reason why I couldn't hear the caller or the person I called.I was trying everything.Thought it was maybe titanium, maybe adaway, and so many innocent other apps like exdialer.But I have definitely fixed it now.

I had thought adaway because if I updated the hosts, it would need reboot and then it almost always didn't work.But if i rebooted enough times , wiping cache and dalvick sometimes, and others just off and on till it worked, it would in the end work.But I switch off to charge and it more or less always stopped working again.Also any reboot after it was working would stop working after it was rebooted!!

Same if I tried to restore backups that had been working, because after restoration I would reboot.

It seems kind of obvious now that its working, why it wasn't

I have tested it with loads of reboots and charges and it is fixed for sure.

The reason it was not working was openrecovery-twrp-2.4.3.0.

I love TWRP and have used it for ages, as my recovery.

I discovered it was that because I installed an old rom ,(and with it an older TWRP), and it worked great till I updated to twrp-2.4.3.0, then it was same as before after reboot, couldnt hear caller but they could hear me.So I updated to twrp-2.4.4.0-n7100 and everything is working again, even the backups I had made that were bugging the hell out of me because of the caller issue.

Now I don't know if I had a bad download of 2.4.3 or if that was just a bad recovery, so perhaps anyone else using that version of TWRP will have no problem, but I do know that, without doubt that was what was causing the Couldn't hear caller issue for me!!!

Kernels ,Roms, and all the wipes I could possibly have done in the last 24 hours didn't fix nothing because one thing remained the same!, my recovery.

I hope this helps someone that may read this, because I have hardly slept.Began trying to track it down since about 6pm last night,kept doing wipes etc till 4am.Worked in morning till 2pm and just finished fix now at 6.30PM.

This has been bugging me and almost making me hate the Note 2 which I love completely, for ages.I got TWRP 2.4.3 about the 3rd of march, so this has been driving me nuts since then.

All is well again, and Monx, thanks for this great Rom :)
