I recommend to buy this product

I had purchased this phone for my father in February 15 and since then this phone is doing very well with latest andriod lollipop 5.1.1.

Feature and hardware wise this phone is to awesome and this was the my expectation from the phone with this price. Battery backup is good and even touch is also doing well.

Like everyone else I do agree to the fact that this is a great device within anyone's budget but the battery backup should have been better. 1700 mah is not upto the mark when compared to the screen offered with the device, 2000 mah would have been appropriate in this case... Hence four star and that too solely for the performance at this price range..

I have been using this device for about 5 months now, and I must say that is an awesome deal.
Pros:
1. Stock Android (Upgradeable to android 5.1.1). This speaks for itself. Also, more updates are planned.
2. Extremely handy. 4.5 inches screen is neither big, nor very small. It is just perfect.
3. Great build quality.
4. Battery backup. I get 4-5 hours of screen-on time with mixed usage. The wifi is on for about 80% of the time. On low-moderate usage, the phone lasts for 1-2 days with screen o...

I purchased this mobile last week, but not from flipkart. I am reviewing the mobile here for the reference of other Android enthusiasts. I really love this mobile. It is very handy and light weight, though the back cover is delicate and needs proper care. The device got upgraded to Lollipop on its first day usage and the latest UI is really awesome. It feels fluid to touch and swipe on the screen. LED notifications are icing on the cake.
I am not a heavy gamer, but i felt the performance of ...

(Usage after 26Days...)
I bought this phone for the only reason it has android one and it will upgrade upto 2 years. But this mobile gave more reasons why it is needed! I compared this description mostly with Asus Zenfone 5 (8GB,2GB RAM) because I have that one also.
Pros:
1. Battery

(Only problem with Zenfone is battery. At night time it is taking nearly 20-25% battery without any usage)
this mobile using only 2% entire night (11PM-8AM) without any usage.
I played asphalt 8 nearly 2 hours...

Have been using the phone for past one week and have the following review points -

Pros -
Great VFM - There aren't many phones with such specs with a sub-5k price point.
Android One with Lolipop upgrade guaranteed by Google
Good looks, resolution of screen and UI
Very good sound quality
The box contained a free 8GB SD card which came as a surprise :)
Free screen guard comes in the box.

Cons
The camera (though is of 5MP) does not produce high quality pics.
Comes with a few pre-installed apps...
