Each time I use the speakerphone, the person on the other side of the call hears an echo of their own voice. This has been tested with two people. Switch off the speaker and the echo goes away. I will test with a lower speaker volume, but it is weak even at 100%.
Yes - we are aware of this issue and already have a fix as well. It will come with the next SW release.
I just got my phone working today and it does not have that problem.
Same issue here
