Sony Ericsson Xperia arc Questions & Answers
Xperia arc user interface

I really, really liked SE in the past. Had more than three handsets with the SE brand, and I absolutely loved 'em. I hope they'll change the blue interface cause it's driving me nuts. The black one is gorgeous!
Display mode:
Every one manufacturer puts something over Android platform to be unique like HTC Sense UI.
Well, they have no choice, the have to differentiate their products from the other androids on the market. Moreover the stock android interface is pretty plain.
I've had the chance of playing a bit with this interface and it looks great and has descent functionality, but in reality is quite demanding on the hardware and most of the times ran slow or lagged. It may run good on one of the 1GHZ monsters though.
On a fast CPU it should run perfect like everything else, but to me this interface is not that well thought out in terms of coding. It is not optimized to use minimum resources as it should have been.
Ok, this phone has "1GHz ,onster", so I think the UI will be fine, as to lagging there is a lot of apps, that fix this problem :)
If the user interface is not optimized, even 1 GHz CPU can't help you, and the phone will be lagging...sadly but true.
