Modern multimedia capabilities of smartphones require a huge amount of free space for storing photos, videos and applications. Owners of Xiaomi, Redmi and POCO devices often face a lack of built-in storage, especially in low-end and mid-range models. Installing an additional microSD storage format is the most affordable way to solve this problem without losing important data.
Memory expansion does not require any technical skill, but requires careful handling of the physical components of the device. Incorrect insertion of the tray or ignoring formatting can lead to the system not seeing the new media. In this article, we will discuss in detail all the steps from tool preparation to setting up the system to work with files.
It is important to understand that not all models support this feature, and some have a combined slot. Before buying a card, you need to make sure that your gadget is compatible. We will look at the nuances of working with the MIUI and HyperOS shell so that you can maximize the potential of your device.
Compatibility check and selection of memory card
The first step before buying is to accurately determine the specifications of your smartphone. Not every Xiaomi device is equipped with a slot for expansion, especially the flagship models of recent years, where manufacturers are betting on cloud storage. You can find out about the availability of the slot in the specification on the official website or in the Settings application → About the phone → All options.
When choosing a drive, it is critical to pay attention to speed class and volume. A card that is too slow can cause delays when recording videos or running applications. The best choice is Class 10, UHS-I or A1 cards that provide stable read and write speeds.
💡
Pay attention to the A1 or A2 marking on the package – this means that the card is optimized for working with applications, not just for storing files.
There are limits on the maximum amount of supported memory, which depend on the processor and version of Android. Although modern systems often see drives up to 1 TB and even 2 TB, for stable operation of older models, it is better to limit the volume of 128 or 256 GB.
- 📱 Check the exact model of the device in the settings or on the back cover.
- 🔍 Review the technical documentation for microSD card support.
- ⚡ Choose cards with a write speed of at least 30 MB/s to write 4K video.
- 💾 Consider the maximum volume supported by the manufacturer.
⚠️ Warning: Buying memory cards from unknown brands with suspiciously low prices often results in quick data loss.The original SanDisk, Samsung or Kingston products cost more, but guarantee the claimed resource.
Preparation of the device for installation of the storage device
Before you start physical intervention, you need to properly prepare the smartphone. The main rule is that the device must be completely turned off. Turning on or off the memory card "hot" can lead to software errors of the file system or, in rare cases, to damage the power controller.
Find a tray for SIM-It's a map that's usually on one side of the case, and depending on the Redmi or Xiaomi model, it can be on the bottom or on the top. To extract the tray, a special clip is used, coming in the kit, or a thin point, which must be carefully inserted into the hole next to the tray.
☑️ Preparation for installation
It's important not to confuse the clip hole with the microphone, which is often located nearby, press with moderate force until the tray pops out. If the tray is not removed, do not use excessive force - perhaps you are pressing in the wrong direction.
