a front cover assembly attached to the outer periphery member and having a front glass member formed of a first glass material, the front cover assembly defining a front surface of the electronic device and a second portion of the external sidewall; and
a back cover assembly attached to the outer periphery member and having a back glass member formed of a second glass material, the back cover assembly defining a back surface of the electronic device and a third portion of the external sidewall; and
a display positioned within the enclosure and attached to the front cover assembly.
10. The electronic device of claim 9 , wherein:
the front cover assembly further comprises an interface member;
the interface member is bonded to the front glass member by an adhesive; and
the interface member includes a side structural member that defines at least part of the second portion of the external sidewall.
11. The electronic device of claim 10 , wherein:
the side structural member at least partially covers an entire peripheral edge of the front glass member; and
the side structural member is formed from a polymer material.
12. The electronic device of claim 9 , further comprising an internal platform attached to the outer periphery member and positioned between the front cover assembly and the back cover assembly.
13. The electronic device of claim 12 , wherein circuitry is attached to the internal platform.
14. The electronic device of claim 9 , wherein:
the outer periphery member is formed from one or more conductive metal elements; and
the one or more conductive metal elements are configured to operate as an antenna.
15. An electronic device comprising:
a display;
a camera positioned along a side of the display;
an enclosure surrounding the display and the camera, the enclosure comprising:
