Hi! This is my first review. I bought sony xperia m few days back. These are the pros and cons that I have found out in the one week duration.
Pros:
1) the phone has NFC and Wi-fi Direct Technology which many phones in this price range do not have.
2)the price is on the cheaper mid range side.
3)the battery backup is decent for a smartphone.
4)the audio is good both on speakers and in headsets.
5)Since the processor and RAM is very good, you can play almost all games but those which would fit under the 2 GB usable internal memory.
Cons:
1)The camera is bit on the lower side and it does not stand up to the specification 5 MP.
2)The phone gets heated up after 30 mins of gaming and heavy usage.
3) From the internal storage of 4 GB, you can use 2 GB only.
And on the whole, if you dont want to spend much but get a decent and gud android phone(SONY btw!) cheer up and buy this.
