Hmm,so far the only thing i can remember is the arc will turn off by itself when its in my pocket...After awhile it's fixed by its own,maybe fixed by software update,not sure..
Also,the video recording is a little bad as the audio and video is not in sync..
Not to mention theres the hairline crack at the sensors...
Last but not least,the chrome paint part which will fall off after some time(about a year) which makes it looks ugly..
And i bought the phone ori set on 1-4-2011 at a price of 1950..
So expensive and it depreciates sooo fast...dropped a few hundred after 1 or 2 months..
Think this time if im gonna buy it,will compare with htc one and samsung s4 1st. Im a sony fan,but if the xperia z is smoked too far behind by htc/samsung then i will not get the xperia z..Also,i will definitely get ap set and wait awhile for the price to drop a little first..
I bought my arc bout 1200 or 1400 i cant remember, but an ap set. Until now i love my arc however due to its single core proc n very low internal memory, my arc lag frequently n i unable to update most of the apps. Build quality is good altho it is plastic mostly. But i did has that hairline crack at the sensor area. My chrome paint is still like new as i protected it wit tpu case ever since i bought the phone. The arc looks very sexy without the case but it feels too fragile, i always feel insecure when it is naked, so i sacrificed the sexiness for better protection.
