Sound Reception: Xperia Ranges have never disappointed me interms of Sound Reception and call quality. Same goes for XA 1. this is the successor to Xperia XA and yes it is better in terms of sound reception. theres no hick up during calls, no lags and the sound is clear and crisp.
User friendly: in terms of User Interface and skin, Sony has Its own customisation on top of the stock android. Here I would say that these customisation are the perfect balance between the stock experience and UI experience. Sony played it well by changing things in UI in some specific places rather than changing the whole experience. The UI is simple and has smart assisting features as well. you can change colour temp, adjust it to reading mode. You can use image enhancer, sound enhancer which sony has provided for Vivid screen and crisp, clear and loud sound.
Other features: Let me take you straight to its 1 of the main attraction that is its 23 MP Exmor camera. I mean a 23MP shooter in price tag under 20k by a brand like SOny. Camera Performs Literally too good. It never leds you down, I mean Never. Even it surprises you with the shots it gets for you. Not only the good quality lens but the image processing also plays a vital role here. In low light performance this image processing helps you a lot as the flash provided is not so high ended. Also for Pro shooters you have a pro mode. SO a thombs up there.
Style and design: Flagship, this is what I can say. in 20k you are getting an Border less display which is as beautiful as it can get. You will fell in love with it. The body is an unibody with same colour n whole body. When you gonna take this out of your pocket, its going to attract everyone around you.
Extra: now there are few important that id like to tell you. This phone just has an HD scree. which is not bad if you look at the screen size and it does not make the display bad at all. but A Full HD would have been better. Also there is no fingerprint sensor which is so popular these days and also quite helpful. the performance of phone is good and satisfying, no problems or lag but I dont know why Sony choose to go with Mediatek rather than Snapdragon.
Value formoney: a fingerprint sensor, a full hd screen and an infrared I would have rated this as the best value for money. But still it offers you quite a good value for money looking at its style and camera performance.
