Review: Sony Ericsson Xperia X10
Calls
There are several avenues to making calls with the X10. Since there are no physical Send/End keys, you have to rely wholly on the software. One of the four icons at the bottom of the main home screen is for the phone. Press it and you have a slightly redesigned Android dialer. Sony Ericsson has moved the four tabs that normally appear across the top — Dialer, Call Log, Contacts, Favorites — to the bottom of the screen. Otherwise the phone app functions much like it does with other Android handsets.
In the call log, for example, there is a green phone symbol to the left of each call. Press that to make a call. There's also an arrow (red or green for placed or missed calls) to the right of each call log. Press that to go to an informational page about the call entry. Press and hold over the actual number and the full set of options pops up, allowing you to call the number, send an SMS, add it to contacts, etc.
Call records also appear in the TimeScape Spline. They are filtered among and between all your other messages. If you happen to be interacting with TimeScape, you have access to all your logs there, and can get all the same information.
Contacts
The main contact application is nearly identical to every other Android handset. The X10 syncs with your email accounts and automatically populates your contact database with a user's Google account. Perhaps the one notable difference is that Sony Ericsson has added a touch of TimeScape to the way information is displayed on each contact card. The first page presents the contact's basic information, and you can swipe sideways to see recent messages, recent photos (if synced with Facebook), and other information. It's visually appealing, but it was a little slow to interact with.
Otherwise, all the same tricks and functions are present.
