Hey freinds.I purchased this product last month and I felt camera is awsome specially auto focus with good filters too.Its slim and light weight but the only problem I faced with this product is when I open whatsapp, it gets hang and even if I open my web browser too.So I need to restart my phone again and then use it.According to me Redmi Note 4 is better in terms of price and features too as its cheaper than this product.In less price, we are getting good battery backup, good quality camera, good processor, user freindly etc.
