I got this phone after switching over from Verizon. The first thing I noticed was an audible hissing when I'm talking on the phone. I went to 3 different sprint stores and tried out all the models that were available and there was noticeable hissing on almost all the phones. But most notably on Sanyo models. The phone that had the least background hissing was the LG 325, but I wanted a flip phone. The PM 8200 also has a horrible speakerphone (it's loud, but very distorted and cuts out when there is cross-talking). The PM 8200 also distorts the caller's voice slightly. If you've never had a good cell phone like an LG, (my previous verizon phone was the LG 4400 and callers sounded crystal clear), you may not notice the relatively bad sound quality of most of the Sprint phones. I returned the 8200 within the 14 day period and instead got the Samsung RL-A760. The sound is much clearer on this phone with less hissing, but is slightly larger and does not have a camera. the speakerphone on the Samsung is much better and does not cut out during cross-talking, at least on my end. overall, the PM8200 is a good phone if you can stand the hissing and distortion.
