Hi all. I got my hands on my first Sony phone yesterday on upgrade. I saw the z2 specification and thought wow! What a phone! So took a punt and went for it. However I have played with some settings and in all honesty, I'm not sure if they actually cause more problems for me the caller or the person on the other end. i'm referring to" Microphone Noise Suppression Speaker voice enhancement equaliser "normal, bright and smooth" Clear Stereo Clear Phase x Loud sforce front surround The list goes on... Now don't get me wrong. I think it's cool to have a phone with all these features but I'm just not sure why it's on the phone, when to use it and why to use it? I've tried to find any detailed information on each setting, and why I would use it but I can't find anything. So if anyone can tell me what the optimised settings are for this phone or if I even need to have any of them switched on I would be very grateful indeed. I switched on a few and found the call to be static on some occasions compared with them off and on others the other person on the end couldn't hear me very well... headache..
