The Nokia Mural 6750 offers a brilliant display and a sturdy construction. The functional feature set includes 3G and push-to-talk.The external display is hidden when the backlighting is off. When it's active it shows the time, battery life, and signal strength. It also displays numeric caller ID, but it won't show photos attached to contacts. Below are three music controls for activating and using the player when the phone is closed. They're a bit thin, but we didn't have any trouble using them. The remaining exterior controls include a volume rocker and the PTT button on the left spine. The former is easy to find when you're on a call, but the latter is too small and rather stiff. Just below is the headset jack, which unfortunately is just 2.5 millimeters (we prefer a 3.5 millimeter jack). On the right spine you'll find the Micro-USB port that accommodates both a USB cable and a charger. We applaud Nokia for moving toward the Micro-USB charger standard.The camera lens sits on the rear side of the phone. There's no flash or self-portrait mirror, but you can use the reflective skin to get vanity shots. A speaker sits on the bottom of the Mural, and the memory card slot is behind the battery cover. That's not the best place for it, though we're glad you don't have to remove the battery as well.
