Phone is totally waste of money. it has not good user interface. user interface of this phone is very irritating and copied also. build quality is poor and not worth of money. there is many more better choices in this price range. redme note 4 is competitive phone against oppo a57. oppo a57’s only good camera nothing else. phone’s battery backup is weird it runs only for 7-8 hours. pixel dentisty is average.sound speakers has not clear output as it should be. no doubt oppo is a good and huge brand but oppo a57 is not a good option to buy a budget phone.
