Display & Audio

The N93 has two displays. The main (internal) display is a 2.4" active matrix LCD capable of QVGA (320 x 240) resolution and up to 262,000 colors. This is a beautiful display, second only to the newest QVGA+/16 million color models just starting to appear on mobile handsets. An ambient light sensor provides automatic brightness adjustment, and
Nokia claims a 160 degree viewing angle for this display.
I found the display to be bright, crisp, and easy to read in almost all lighting conditions. As I mentioned, watching videos in widescreen Viewing Mode on the N93 was a real treat, and the display also performed quite well for text-based tasks such as Email and reading Web pages.
The secondary display is a 1.1" LCD capable of 128 x 36 resolution at 65,000 colors. This display is primarily used for basic information - time, date, phone status, caller ID, profile selection - though the nifty startup animation does show that it's capable of rendering small images as well as text.
Call quality on the N93 was very good. The handset features dual mode WCDMA/GSM and triband GSM coverage on up to five continents. In the US, the N93 uses the EDGE/GSM 900/1800/1900 bands, which are compatible with Cingular, T-Mobile, and other GSM networks. I used the phone on T-Mobile both in the San Francisco Bay Area and on the island of Kauai, HI, and calls came through loud and clear in almost all cases.
Quality was also good using the built-in speakerphone. The N93 supports multiple profiles, each of which includes settings for ringtones, system and alert tones, and vibrating alert. Profiles can be switched while the handset is folded shut by way of a top-mounted profile/power button.
Bluetooth 2.0 on the N93 includes support for headsets, and I was able to easily pair and use a mono headset for calls. Stereo over Bluetooth is not supported, though an optional wired stereo headset can be connected via the Pop Port.
