When I buy oppo a57 .its was looking slim comfrt and good. But only some things are wrose in this product. Compare to vivo and else. His battry pic up is low. When it comes to 2% .it didn’t tak time to work on. The sound is also not too good. And one anther the most thing front camera. Its front camera is very bad. Not clear only mentioned 13-16 mp only name thing. Not good quality of camera speacially front is very bad.
