I think that it is small in size.I is 3g phone not 4g because I like 4g hand set.This phone has ram and rom less because ram is only 500 mb and rom 4 gb.Its battery is so less. Its camera qualty is not good.Its feture are not good.Its internet and operating system is very bad and slow.Its video qualty is not very good.I think that any person should not buy this Sansung Galaxy star Duose mobile phone. Its storage is very less and this mobile phone is not perfect for profetional person.Over all this phone is not good. Thank you and have a nice day
