Oppo A57 is very nice phone. Its fingerprint lock opening option really good. Its build quality very best. Its camera is also good. If u work or eating, and there is a incoming call on your phone you pick up call without touch. On this software really really good. Its very lightweight.its a stylish latest phone. Battary backup really well. Its charger is quick charge to battary. Its front camera is 16 mp and rear camera is 13 mp. So it is a selfie expert. But its main fault is that its price is very high.
