I have not seen this type of worst phone in my life.It hangs a lot .I have to format the phone 5 times a month.
The specification of the phone is also not so good .And in this phone you may have to face random problems such as Phone reboots automatically , Battery drains faster then expected, Gallery crashes everytime.So in the market in this price we can buy Smartphone with better specification.So from my opinion it is totally waste to buy Samsung Galaxy Star pro.
