6.5-Inch FHD Rugged Phone Factory Samples: Retain a Reference Unit

An approved factory sample is useful only if later deliveries can be compared with it. For a 6.5-inch FHD rugged phone, preserve both the unit's identity and the conditions under which it passed evaluation.

Record the reference configuration

Save the model label, hardware revision, firmware, display specification and accessory set. Document application versions and settings used in the trial. Photograph the enclosure and connections to support later comparisons without treating photographs as a substitute for functional checks.

Maintain usable test materials

Keep the accepted form, map and touch-task examples. Store the reference device securely and follow its battery care instructions. Plan how to compare production firmware if it legitimately changes before delivery. A reference with undocumented settings makes later differences difficult to interpret.

Review deviations before acceptance

Ask the supplier to explain changes in panel, enclosure or accessory fit. Repeat affected checks on the delivered configuration. X5 is currently 5.3 inches, so it cannot serve as proof of an exact 6.5-inch FHD sample. It can be retained as a separately approved compact alternative. Keep the approval record tied to the actual device tested, making clear which deviations were accepted and which still require resolution.

Review the X5 product details for the documented compact configuration.
