Fortunately, the model supports expansion via microSD cards to 256 GB. However, many users face problems: the phone does not see the card, does not allow you to move applications or requires formatting. In this article, we will analyze the step-by-step installation, configuration and solution of typical errors - with the nuances of the Redmi 5A.

• 🔹 Speed class: minimum class 10 (UHS-I U1). To record video 4K Frequent file transfer is better UHS-I U3 or A1/A2 (optimized for applications).
• 🔹 Brand: reliable manufacturers - SanDisk Ultra, Samsung EVO, Kingston Canvas – Cheap no-name cards are often forged (the actual amount is less than the stated amount).
• 🔹 File system: for cards up to 32 GB — FAT32, from 64GB - exFAT. Redmi 5A supportive NTFS!

⚠️ Note: If you plan to use the card as internal memory (for installing applications), take a model marked with the name. A1 or A2. Regular cards (even Class 10) will severely slow down the system, and note that once formatted as an internal drive, the card cannot be retrieved without losing data.

Should you overpay for high-speed cards? For the Redmi 5A, the difference between the U1 and the U3 is almost imperceptible — it limits the smartphone's slow memory controller. But if you often shoot videos in Full HD or transfer large files, you'd better take the U3.

2. Preparation of the phone before installing the card

Before you insert microSD, follow a few important steps:
