Samsung has introduced the Galaxy A03, a new budget smartphone that succeeds the Galaxy A02. The Galaxy A03 has an octa-core SoC, a 6.5-inch display and a 48 MP primary camera. The Galaxy A03 will be available in three colours and three memory options.

For all that is worth, Octa core doesn't mean much, neither does that camera. You can bet Samsung isn't splurging on that to make any of it truly good.
