Display, performance and software
Display
The launch report gives a 6.59-inch screen with 2510 × 1156 resolution and 419 pixels per inch. PConline lists the panel as OLED with a 120Hz refresh rate; those two panel details come from a secondary listing rather than the launch report.
Processor and cooling
The reported chipset is Qualcomm’s Snapdragon 8 Elite. The launch report also describes a three-stage circulation cooling system using the translated product term “Ice-Sealed.” The supplied specification details do not quantify performance, sustained speeds or temperature, so the chipset and cooling description alone should not be read as a benchmark result.

What to verify before buying outside China
The reported launch and network details are China-focused. International availability and current retail terms are not established by the available information. Before buying an imported or region-specific unit, verify:
- Whether its exact model supports the 5G and other network bands used by your carrier.
- Which firmware and languages are installed, and whether your required apps and services work as expected.
- Whether warranty service, repairs and parts are available in your country.
- The seller’s present price, stock, return terms and exact RAM/storage configuration.
PConline’s band listing is a secondary China-market reference, not proof that every K90 unit works on every carrier. Match the bands for the particular handset to the carrier’s requirements before purchase.
