From a sony hater who migrated from samsung to sony, its AWESOME.
So let me do one thing and start with the cons and point out what is misconception and what con you might actually feel -:
1) Front camera is VGA - seriously front cam is used for video calling and no video calling app supports HD quality.so its camera is gud enuf to make video calls and that won’t be a big problem.also it works pretty good for face detection.
2) Call volume is low - This con posted by some users of this phone really surprised me.as either they are using the smartphone for the first time or they are pretty DUMB.Actually sony has provided an equalizer setting within call setting and if you do not feel the voice is loud enuf then change it to "bright’ mode and call volume will increase and everything will be crystal clear.
3) Camera quality is not as per expected by 13 MP - If you leave the setting in default(superior) mode you may get average indoor pics but outdoor pics are awesome.you will have to flirt with the camera settings to get good indoor and low light pics.I did it and am pretty satisfied.and its far better than Nexus.
4) Heating problem - If you play heavy games and do multi-tasking then any android phone will heat up.I personally checked and it heats pretty less in comparison to Galaxy S3/ Nexus 4/ Xperia Z.and you guys know that its water proof so when its over-heated put it inside water for sometime and you would be good to go again.
5) Internal memory - hmmm.being an avid game player and a techie I felt that this is a little con of this device.you wud get only 4.5 GB available.but you have the option to have external micro sd card and after that 4.5 GB is enuf for android apps or even big games.and you can root the device and change settings so that the apps will install on memory card.
6) Its not water proof - literally I was completely shocked to see this con.well guys let me tell you when I received the phone from flipkart, the first thing I did was to start it and then put it in the water and check.and me & my friends were shocked to see that its really water-proof.BUT sony says that its flaps(audio and usb) should be closed properly and the back cover also fitted properly then only it will work in water and sony do not give LIQUID-WARRANTY.so do use the phone in water but be very careful.
