I was using Moto Z2 earlier but had lost it and then I have purchased this phone. It is very nice built phone and gives you excellent grip. Camera is good and battery performance is also quite good. It lasts for almost a day to me with very heavy usage of Jio sim card. One can definitely buy this phone for sure.
This is my second motorola phone and first purchase from OnlyMobiles.com - I got better deal of 5% instant discount which was not available on flipkart so I have purchased from onlymobiles. My experience with OnlyMobiles is good and I will recommend others also.
Coming back to the phone, I have used Motorola Z Play earlier but I have lost that phone. So I had purchased this phone. It is a good upgrade and phone navigation is quite smooth and fast. Phone does not have any kind of heating issue. However, compared to Moto Z Play, they have reduced the battery capacity. Overall, It is a good phone.
