The SP-120 is in almost every respect a good smartphone that I can only recommend. However, my demands on the acoustics are higher than the Phone can afford it. Since the unit was reengineered, I was hopeful. For Little calls the audio performance during a call may be sufficient. I unfortunately it was not enough. I felt the sound as dull. The micro-headset only works if you put it with a lot of pressure in the unit. Convincing the quality through the headset was not. Therefore back!
Still, I was impressed by the good hardware as backlight, good camera (5 MP), everything ran smoothly, apps, videos in HQ, data transfer, GPS, all ran smoothly and smoothly.
