switching off the ok Google recognition doesn't change. Still echo issue I tried latest built from Paranoid Android, RR Rom same issue with the echo switching speakers on and off during the call Reliefs from the echo if I put tape over the microphone at the Button - > no issues at all with echo but the person I am calling with cannot hear myself very well I updated and tried many Firmware and Modem drivers including the latest. No change still echo it has definitely something to do with the noise cancellation Software of the phone.
Does anyone can help me? How can I switch off / Bugfix The noise cancelation Software?
I didn't find the right solution from the Internet.
