This is very good product according to me , because I bought this phone in ₹8k from amazon, in this price range a phone with sd820 , unbelievable , no doubt the zui is very bugs firmware , but you can flash custom rom , and the performance after custom rom , the beast , no lagging , no heating issues , you can think that a phone with sd820 in 8k its a best ever deal
Flash custom rom own thier own risk
