OPPO A57 is a good product but not valuable for money.
A Good looking premium design with a metallic body.
Phones come with a Fingerprint scanner.
It’s rear camera is OK but front camera is definitely very good it dose justify the name and price.
Phones much smaller for single-handed usage phone feels like at 145 grams. It has a thickness of 7.65 my for my huge hands it feels comfortable to hold and dose not feel slippery at all.
Battery is not good for gaming. Average Battery capacity.
The screen is not full HD but is has 2.5D glass with Gorilla Glass 4.
Front camera performance is fantastic.
Android version is 6.0 You will not get android Update.
Prosesor is not first for this price range. Chipset is Qualcomm MSM894O Snapdragon 435 with Octa-core prosesor.
Overall Phone is good for normal use. But Phone doesn’t valuable for money.
