Telephony
The voice reception and the microphone quality is attributed to the upper class. The ear speaker is so loud that I have to reduce the volume to 3/4.
Multimedia
The installed graphics chip is certainly not good. I use the phone to play hard (only Tentacle Wars occasionally and a few others who are going very well). But I can not judge. The volume and sound quality to the headphone jack were better at the ZP100. At high volumes of vapor missing (the bass definition is really bad) and I had to perform a registry hack to raise the final volume anything typing (on Telefonwählpad: * # * # 3646633 # * # *, then at Hardware Testing -> Audio - > Media values lift). In the last 2 volume levels of the audio chip distorted. No, I'm not deaf, I never reached the last 2 stages in the ZP100, because there was just too loud to me. This is a real shame and 1 point deduction worth. Unfortunately ZOPO can not help it because they buy the SOC and lousy audio chip is there with it, but it weakens the otherwise good performance of the product.
Connectivity
Everything was great, except for GPS. Thus ZOPO probably big problems. When ZP100 it was just as slow. It takes forever just until it finds satellites (> 1min).
Quickness
Super smooth, I can not complain absolutely. The 1GB let me many apps at the same run. Switching between apps is also lightning fast.
All in all I am very satisfied and if the phone a friend, I am a person who has not like expensive smartphones, because there are commodities for me and it would be even more unfortunate if they break or are stolen. This target group speaks the phone certainly.
