My friend told me this SKYPE and I approve this problem. When you flash INDO Update (2.2.2) and install SKYPE. The speaker is loud when when make the call. Then you flash either Froyo Stable or FroyoFusion and install SKYPE again, the speaker is silent but you can talk with earphone. But you close the SKYPE and you can not have ringtone for incoming call until reboot the S7. I install Chinese Messenger QQ for iPAD. It have optional music player when you use messenger, but no speaker output when you want to play music (earphone is OK). Same no ringtone for call unless you reboot. Please help to verify this problem and hope Joe can fix that problem.
