For the last 2 to 3 weeks (was all good before this), a friend on 2Degree Mobile (was ported a couple of years ago from Telecom 027) (Handset is a Samsung S4) is having a problem and has asked me for help. Her problem is she hears her own voice back about half a second delayed when she talks on her mobile.
I did some testing such as... Changed settings to Auto 3G/2G (was on Auto 4G), and I called both my landline (Parnell landline, with handset in Parnell also) and another mobile (Spark) and put her SIM in an older alternative handset (a Vodafone model 858Smart - non 4G). In all cases the loud echo (as loud as the person she is talking to!) is there. With the call to the Spark mobile the echo was not so obvious, but was still there.
The problem is not location dependent either, as it occurs at my home and at her work in Ellerslie.
I had a quick Google search to see if this is a known problem, but I found nothing.
Has anyone got any suggestions or advice before we lodge a fault with 2Degrees?
