I buyed Asus Zenfone Max 2016 edition from flipkart.I start using it but I face a lot of problems and one of the major problem is its speaker.Its speaker was very very quiet at all.Not at all loud.I seems that there is no speaker in the phone.Another problem is its calling speaker it is also not good at all.Its calling mic is worst ever.When ever I make a call from it the person who is talking to other side was not able to hear my vioce clearly and loudly and I also not able hear the voice of him clearly and loudly.So I commit a very big mistake by buying this.
