Today, I am going to review about Oppo A 57 phone. First of all, I want to. tell you that I have purchased this phone 2 years ago at Rs 14000. Its camera quality is good that is front camera is 16 MP and rear is 13 MP but it has got only 2900 mah battery which lasts for 5 to 6 hours only if charged fully. Secondly, its storage is only 32 GB which is also a drawback of this phone. Thirdly, there are no android version updates in this phone since 2 years. It is android version 6.0 , that is, marshmallow from last 2 years. It is costly also and sometimes it hangs in between while playing game or opening youtube most probably due to its low RAM, that is, only 3 GB. Sound quality is good. but sometimes takes too long to respond. It has average fingerprint sensor. So, I am very disappointed after buying this product.
