Now iam using asus Zenfone max pro m1. The last six months usage, l agree for u this is a great smartphone in india. I have using 4gb ram 64 internal memory varient. no hanging and heating problems. The phone also added to fingerprint security and face detection unlocking system. Iam really shocked for this phones battery performance. 2 days average using time. iam totally loved asus zenfone max pro m1.
