I noticed a strange issue in Samsung Galaxy Spica (running Android 2.1). At times, the normal speaker and mic would stop working and one would not be able to hear or say anything for incoming or outgoing calls. On an outgoing calls, even the ring is also not heard. Its complete silence. However, if you attach the earphone or enable the loud speaker, both speaker and mic work perfectly fine. Reproduction of Issue: I'm unsure how this issue can be reproduced. Fix: The fix too is not certain, but I've found that switching the loudspeaker on and off while on a call re-enables the normal speakers and mic. At other times, connecting the earphone and switching the loudspeaker on and off works. Has anybody else encountered this issue? Is there any certain fix for it?
