Attention Attention guys! I want to share some special drawbacks about oppo build handset. First of all its without front flash camera as well as non removable battery. Today I am facing battery problems in which drain battery very fast battery life is average. Front camera is better but rear camera is average( So So) for some time I am facing heating problems but I solved it after software update and focus on 2900mah is insufficient for users. If we discuss about service then its so far from actuall and latest service dealing. Bokeh mode is also very average which provide less effective DSLR photos. Conclusion is Oppo A57 is an Average but not best.
