I have using this phone since 1.5 years ago and did not faced any problem . It is so smooth that whenever I play pubg or anyother game it does lag or hang the phone . If I use for my work for 2-3 hours it does not heat up . Amazing phone and it is best quality when you are working with the phone or playing for 2-3 hours it gives same experience till now from day first . I would recommend everybody that you should buy and get this phone only . I would also tell you that if you get this phone on charging it gets charged in around 45 minutes from 1% to 95% . It is an fast charging phone . In India we get the problem of charging but this phone is amazing absolutely .
