    What customers dislike about Xiaomi Redmi K80 Ultra (16GB + 1024GB)?

    • The camera system is considered a weak point; while the main 50MP sensor is capable, the other sensors (ultrawide, front camera) are described as mediocre, lacking dynamic range and having edge distortion issues.
    • The phone runs the China version of Xiaomi HyperOS by default (as the global version may not be widely available under this name), which requires some tinkering to get notifications working perfectly out of the box and has limited customization options compared to other Android skins.
    • It does not have an LTPO display, meaning the refresh rate is mostly limited to 60Hz or 120Hz/144Hz in specific modes (e.g., gaming), rather than dynamically adjusting.
    • The device does not support expandable storage (no SD card slot).
    • No 3.5mm audio jack or wireless charging support.
    • Connectivity/network compatibility issues reported in some specific regions (e.g., lack of full 5G support in the Philippines).
