They have introduce active sync that is awesome also Pinch Zoon feature is excellent. Touch Response for REX series seems to have upper edge as they are capacitive in nature and very smooth. So they have called as smart Feature Phone.
I bought both brands, one has poor software, for same purpose do more pushing of buttons, and more fragile. another has two sockets in the name of dual sim, one should be off when another in on. salespeople of both are big fords.
