Yes, the Samsung galaxy core2 is a worst phone in a brand like Samsung galaxy.
My brother has brought this phone few months before and he was upset with his choice that he made about the mobile phone.
He and I found that , This phone was horrible with battery life.And terrible with slow speed .This phone has 4 gb internal and 768 mb ram.This 768 mb ram makes the phone slow in speed though it has quad core processor.
This phone gets hang up frequently.Its front camera has also made me feel upset.I didn’t liked this phone.I would like to give 2 stars because the price value is less.But I would like to tell others, make a sensible and smart decision while selecting phone.
