I purchased Mi4i previous year in online Sale .
Initially camera, sound quality and User interface was normal ( expected) but after 1-2 months it started lagging . It's camera has full dist inside it and is total waste to me now.
Initially it was moderate in usage and design is also normal not special.
Yes it is value for money but only for those who have to use it maximum for a year or two.
At last it is not durable as it is a chinese product my screen got broke when it fell down and Company is charging 3500 for screen .
Not recommended
