Oppo the brand which just buy india cricket team sponsorship for more than 1000 crore to make their way in India market somehow they are doing it well but not in the case of F series which selfie expert I m talking about my latest buy F3s which I totally waste my money someone its promtion my company is too much so I use to buy this without thinking anything but now after using this I feel bad that instead of camera it just a simple phone like other oppo mobile phone not much to do its camera is good but u know its back camera I use to beat with my iphone 5s so that was very bad to see its battery life is average not so impressive for me.one of the main problem its size its too big to hold with one hand as we all know we take selfie generally with one hand but its size is not fit in one hand that will make you problem during selfie overall I just waste my money in this one its sound response is just average not much.not a value for money
