I bought Samsung Galaxy III a year ago.
Recently (for about 2 months), when I use speaker phone to talk, during my conversation, the phone turned off speaker phone by itself but the light on speaker phone was still green. I now learned that I just touch it again, then it turns back on but sometimes I do that, it does not work.
Is it a problem of the phone? or there is something I need to set up which there is no instruction to do?
thanks.
