I want just make a collection for this phone Alcatel OT991.
First of all, this might not be the proper section, but still, the problem I'm referring to was solved on other devices using custom ROM.
I have the same phone and I have a weird problem. I can make skype calls but the sound is played through the speakerphone, and not through the earpiece. The same is true for other VoIP apps - Kakao Talk, Line..... When I tried to use Viber I couldn't hear the other person, yet they could hear me.
I read somewhere, that the same problem occurred with ZTE Blade and it was solved by using Cyanogenmod 7. So I guess this could be solved with a custom ROM.
Here's a link to a forum thread with people experiencing the same problem.
