The Pantech Crossover comes equipped with a 600 MHz ARM processor, which is on par with other entry level Android powered devices. Preloaded on the device is a copy of Android 2.2, which runs fairly smoothly. Most daily tasks run well, but when multiple applications begin running or more intensive applications are loaded, the Crossover begins to freeze. In some instances, a forced reboot was needed as the Crossover stopped responding entirely. Otherwise, the performance is very similar to the LG Optimus T (or S, C, M, U, V), another entry level Android powered smartphone.
The call quality is decent, though there was a bit of static here and there occasionally. Outgoing calls came out a bit robotic while incoming calls seemed to bring in the outside noise along with the caller. There were also occasional dropped calls, but it may have been AT&T's network, not the phone itself. The data also experienced some intermittent interruptions here and there, but once again, the root cause could either be the network or the phone.
The battery on the Pantech Crossover was decent. The battery comes in at 1500 mAh, which is actually on par with many higher end smartphones. The phone was able to last 10 to 12 hours on one charge with moderate usage, including calling, texting and browsing.
