Samsung galaxy y duos is first dual sim android smart phone and very popular at that time all around me I seen this mobile is most of people have this mobile.
This phone have not high configuration but that time is starting of this android so it is good for new customer. It has 290 mb ram which is very less. If phone have 1GB ram phone have good.
Phone camera is okay. mobile battery is good battery backup.
This phone is nit for heavy users who are want to play more game because it is hang after install number of app in it.
