Hi, When you remove the original proximty sensor you have to look very good because there is when you look good at the right sensor a piece you have to remove and put it back in place so the new sensor have to have that little peace too. It's like a little reflecting "paper" you have to put in in the left side where the sensor is in place...
Hi, I had a client who had the same problem... changing the dockconnector was no succes. i try to find the problem and when I left the back case off there was no echo. When I placed it back on the echo was back. So I a placed a kind of foam between the EIM shield and the backcover and the echo was gone... Hope this fix your problem!
