great mobile using for the last 10 days, no issues found ... battery backup is awesome (7+ hours of screen on time). gaming is also good ( butter smooth gameplay in PUBG, Asphalt9).... camera is best in this price range. i love MIUI Than stock android........rear camera is better than realmi u1 and zenfone max pro. selfie is one of the best in this class
Best device definitely a Value of money. Black phone looks much better and premium, Camera performance will amaze you specially of Night click see some my Camera snap, 6 GB RAM is good for huge app & game lover and no lag no heating issues. but 64 GB ROM is not good enough it could be 128 GB or with extra dedicated memory slot.
