What you should know
What matters about this phone
The X300 Pro is built for camera enthusiasts who are willing to accept a more specialist platform and occasional regional compromises.
The documented initial commercial milestone is 2025-10-17 in China original; global later.
Design, screen and everyday experience
Its flagship SoC and premium display give it conventional high-end credentials, but the distinct value is the telephoto- and portrait-led photography package.
Cameras and practical compromises
Reviewers praise the imaging flexibility yet emphasize that different modes and computational processing do not always behave equally well. Regional lens accessories and firmware versions also need scrutiny.
Strengths, weaknesses and the independent review
Notebookcheck’s measured results raise concerns about heat, throttling and merely average battery relative to expectations. A China-imported device may additionally require checks for Google services, banking apps and local network bands.
Notebookcheck specifically questions thermal management and speaker quality despite praising the advanced camera setup. The findings are attributable to Notebookcheck; they are not tests performed by WeraOne.
Who should buy it — and who should avoid it?
Worth considering for: Camera-first buyers who can purchase a supported local model and do not mind software experimentation.
A poor fit for: People needing guaranteed cross-border app compatibility or a low-heat heavy-gaming handset.
2026 purchase, regional and software checks
The Oct 17 first sale is China-origin; global specs and firmware are distinct.
