Problems with Sony Xperia C4

[Taylor18]

Hi,I bought Sony Xperia C4 dual 3 days ago and its working almost fine except a few problems
1)Sometimes the back navigation key and task navigation key switch places(back key would  move right side of home navigation key and task manager key would move left side of home key)when I restart they become normal again.
2)When I close torch, my mobile is lagging for like 7-10 seconds
3)In Facebook, all the options which should be in left side are on the right side(Status),Friends list is appearing on the left side,Like button and Share button switched places(also Status and checkin,)Almost everything is on the other side of the profile I visit
4)In Whatsapp, when I chat with someone, my messages are appearing on the left side and my friends on the right instead of mine appearing on the right side and friends on the left.
5)If Battery shows 'Estimated Battery Life' as 3 hours... The battery is supporting like only 40-60mins.

Its weired to see options on the opposite side on a mobile..

Is this coz of software problem?? Do I have to exchange my mobile? I would appreciate if someone help me with these issues

( I couldn't upload the screenshots here..so i'm pasting a URL)

It's a fault of C4: when you call to someone and they disconnect the conversation before you, C4 will halt & display black only. To make it active again you also can plug in the charger.
In waiting for Sony to repair this fault you can temporarily set: Device>Display>Sleep: to maximum 30 min, then you can call and talk up to 29 min without halting problem if the one you called to hang up before you.
