This is my review after used this phone for 20days. Very bad product from Samsung again. It has same problems what core-2 model had. I think they just changed the name of Core-2 model as core prime and put out in the market. Samsung should note that there were several complaints regarding call/voice clarity in the core-2, and it is the same thing happening with core prime. JUNK. phone.
Why the hell customers pay about 10K and break their head for call clarity. I would suggest not to buy this phone. it even stucks in connecting internet. ringer tone and music sound is very low. Screan clarity is not good either, I compared with one of my other company phone, same image looks too bad in this phone where as it looks better in my other phone.??
