⚠️ Important Notice: Card Slot Usage & Compatibility Guidelines

1. Single-Card Reading at a Time: The NM card slot and SD card slot cannot be accessed simultaneously. Please insert and read only one memory card at a time to prevent read errors.
2. Dedicated NM (Nano Memory) Slot: The smaller slot is engineered exclusively for NM (Nano Memory) cards (the nano-SIM-sized format used in Mate series and compatible phones). It is NOT directly compatible with standard Micro SD (TF) cards unless using an SD adapter in the full-size SD slot.
3. 2TB Maximum Capacity with UHS-I: Supports SD, SDHC, SDXC, and MMC cards up to 2TB operating at high-speed UHS-I mode with USB 3.0 5Gbps bandwidth.
