Sony Xperia Z1 Echo at my end

[Oldnovice]

Hi  I've had the phone for a couple of years but recently started getting echo on my own speech (about 1 sec delay and muffled/distorted but recognisable as my speech). Other party hears me fine and I hear them OK too. It doesn't happen on all calls, but happening more often now. I've tried mic noise suppression on and off and it makes no difference. Any ideas? I have updated to 14.6.A.1.216 and the issue has started since that time but not sure if there's a connection.

What if you boot on >>> safe mode, do you experience the same issue?

In safe mode the problem goes away. How do I find out which third party app might be at fault? I don't have much that wasn't on the phone when new. I use Audio Recorder 2.00.03 and Pocket Casts for downloading podcasts.
