HTC Explorer is considered a low-end smartphone, due to its comparatively low specifications.
It offered Android 2.3 Gingerbread, with proprietary HTC Sense 3.5 custom graphical user interface by the manufacturer.

The rear of the Explorer features a patterned plastic surface with a rubbery, leathery texture to help users to grip and hold the device, with an additional plate of brushed metal at the center of the rear cover.
