I have been using this phone for almost one and half years now. I would say the phone is awsome. When I bought it was 25K and now I can see there is a price drop due to release of higher version and now you can buy for around 20k from amazon.
Phone comes with 5.5 inch screen with gorrila 3 glass so it is quite safe to use.
It has good 4GB of RAM so you never feel like phone is not responding or so.
I have 64 GB internal storage so I never feel like there is any need of adding external storage.
The camera quality I have compared with many of the phones and it has one of best camera in this range of phone.
The only thing I feel little sad about is the battery life. It just lasts for a day with normal usage and for heavy usage it lasts only for 8 hours.
