I am using samsung galaxy core from last two years.I am very happy with this device.5 mega pixel Camera has very very good clarity.Ram is only one gb but except that every thing is ok, nice average disply size that is 4.3 and also has 8 gb internal storage and playing all kind of videos even 720 resolution videos also nicely working. Battery backup is also good enough no lagg at all. Overall samsung galaxy core is best budget 3 g compatible phone.Only slot 1 sim has 3 g support and 32 gb expandable storage.
