I bought this phone after doing extensive online research for a rugged phone. Seems some have this echo issue while others claims it's great. I've had the phone for 3 weeks now and I hate the call quality! A phone should be a phone first! My first 3 calls were met with "what in the world is that echo"! As an audio communication device it is a fail. I'm trying to find apps or ways to improve the call quality, but am coming up empty handed and I am too much of a newbie to root and do a different ROM. Any suggestions folks? I've tried the noise suppression setting off and on during same call, doesn't seem to help. I also deleted the cache for logs I believe in recovery mode, as I read it may help. It didn't.... I use a StraightTalk AT&T SIM. I'm disappointed and could use some solid advice.... If rooting can be proven to solve this issue I'd be willing to try it.. I think MotorHead was talking about version 9 addressing this exact issue... Help... I'm sad.. In retrospect I feel like I should have just ponied up for the Sony Xperia Acro S and been done with it.... Thanks in advance and have a great day!
