The Push-to-Talk (PTT) feature offers a fun and easy way to stay in touch with friends, colleagues, or family with just the touch of a button. This addition also inadvertently fixes one of the biggest complaints of the Z520a - the button to activate PTT replaces the dedicated camera button on the outside of the phone. The camera button was prone to being accidentally pressed while talking on the phone or while in a pocket. The PTT features a lock which minimizes the problem although it still could have been better located elsewhere.
