I have this echo problem on my S2. When I make a call, the other person will hear his voice echo back thru his phone. I contacted DG and they told me network upgrading in Cheras area and asked me try to call from other area to confirm network problem or sim card problem.So I called from other area and echo problem still not resolved.

I changed my sim card....AND the echo problem is still not resolved!

Does anyone have this echo problem? This problem happens for every calls I made and every calls I received, irrespective from/to mobile lines or TM's fixed lines.

Anyone knows how to solved this echo problem? BTW my S2 uses cover.

Thanks. but how do I disable the noise-reduction? My S2 is not rooted cause I am not android savvy.

What is the faster way to backup all my contact?
Some of my friend having multiple number.. so i would like to know which backup method will import n export as per my last save.. everytime i export it still split into different number for the same name

Did u flash the xxtweaker file?

Hmmmm. Thanks. So there is no other way out. Samsung cant repair this problem? I hears S3 and Note are having the same problems on some unlucky units.

Guy, just wanna ask something weird thing happen on my S2 ics 4.0.3. I charged my phone from 9pm till 3am and the battery never full. Sometime stuck at 66% or 80% and the phone is extremely hot. Sometimes it on 100% once I unplug the charger and it will drop to 90%. May i know why?
