The XT800 also froze up a couple of times, especially when we had had an app open and locked the screen with the function still running in the background. The handset that we reviewed came with a 2GB add-on memory card and the external memory on the XT800 is expandable up to 32GB.
The handset supports charging via the USB, rendering the SD card inaccessible when you are charging the handsetvia USB. The battery lasted us for more than a day on a full charge with intermittent use of GPRS (browsing, downloading apps etc) and more than a handful of voice
calls and SMSes. This is commendable considering most smartphones barely last a working day and they are not even working on a dual-SIM mode.
