Hey friends today I am sharing my experiance with xiaomi mi 4i which is good and slim in appearance but its life is not more than 2 months after its warranty which is 1 year manufacturer warranty. As I purchase this phone in september last year 2016 but it gives me hanging problem and battery heat up problem from starting but after 1 month of warranty I faced lots of problem like network problem and app are not running properly thats why I am suggesting you to please avoid this kind of chinease manufacturers.
