Plastic sht.Its Samsung like.
The plastic feel will not translate to this phone. If you look they have a full supporting structure on the body (which obviously means that there will be no removable battery). Samsung's are just back panels that snap in. The phone should be very sturdy and have a higher quality feel to it.
I think there is a misconception about plastics and quality of feel. When done right a plastic phone (high quality plastics) with good underlying structure is not going to exhibit the same cheap feel. Implementation is very important.
