• 🔹 Speed class: not lower UHS-I (U1) Or Class 10. For video recordings in 4K Or to transfer large files frequently, it is better to choose U3 or V30.
• 🔹 Capacity: 32 GB to 1 TB (maximum depends on the model of the smartphone).+ It supports up to 1TB and Redmi supports it. A2 — only up to 512GB.
• 🔹 File system format: exFAT (recommended for cards) >64 GB) or FAT32 (map ≤32GB). NTFS not supported by default!
• 🔹 Brands: SanDisk Ultra, Samsung EVO Plus, Kingston Canvas – Verified variants with no compatibility issues.

⚠️ Note: Cheap cards without a brand (for example, no-name with AliExpress) may have understated real capacity or low write speed. H2testw (Windows or F3 (Linux/macOS). If after the test it turns out that the actual volume is less than the declared, return the card to the seller - it is fake.
