Hi Its Dilip and I’m using asus zenfone max for last 5 months and I’m really happy as I didn’t found any big issue. The camera is far better and low light mode is very effective under low light. The overall gaming performance in great. The graphics are outstanding.The sound quality is ok. The size is great and looks great in hand. The battery is its signature feature which is 5000mah. After complete charge works for almost 2 days.It supports 4g which is also great to access fast 4g internet. With 16 gb internal storage we can store much data, movies and games and with 2gb RAM its performance is also very good.The best budget smartphone.
