Temporary fix but it apppears to work for now. I had this issue on Huawei G300 where the callers couldn't hear me, found a fix on the Internet that seems to work, however if you turn the phone off you may need to reset.
Into the dialler key *#*#2846579#*#*.
This takes you to the engineering section. **Be Very careful not to change anything else!!**
Then go ProjectMenu ->Background setting -> Dual Mic Setting, and turn it to off.
This appears to fix the problem. at least until they send out another update. This works on builds B885 & B892.
