How to allow gallery access to SD-Xiaomi Redmi 8 map: all ways

You've installed SD-map in Xiaomi Redmi 8, but photos and videos don't show up in the standard gallery? Or the app asks for permission to access, but the settings aren't saved? MIUI β€” Android's proprietary shell actively restricts the rights of applications to external drives. In 90% of cases, it is not the breakdowns that are to blame, but the security features of the system.

In this article you will find 4 Proven ways to give the gallery full access to SD-map: from basic settings MIUI We'll take you to the hidden Android settings. 8 (model M1908C3JG/M1908C3JH) It blocks access to files, how to get around restrictions without root rights, and what to do if the memory card is not defined at all. MIUI 12–14 Android-based 9–11.

The problem lies in the MIUI architecture and Xiaomi's security policy, and here are the key reasons:

  • πŸ”’ Limitations of Android 9+: Starting with Android 9.0 (Pie), Google has tightened the rules for accessing external drives. MIUI further restricts these rights.
  • πŸ“ Map formatting: Redmi 8 supports SD-cards up to 512 GB, but if the drive is formatted in NTFS Or exFAT, you might have errors β€” FAT32.
  • πŸ›‘οΈ Protection MIUI: The shell by default blocks application access to root folders SD-cards, even if permissions are given.
  • πŸ”„ Cash Gallery: A damaged cache can cause new files to not appear on the map, even though they are physically there.

Interestingly, the Redmi Note 8 (model M1908C3JGG) has a different solution, but the Redmi 8A has similar limitations, as it is built on the same Snapdragon 439 platform.

⚠️ Note: If you are connected SD-The card to the computer and recorded files directly (without safe extraction), this could damage the file table, in which case the card should be reformatted via a smartphone, not a PC.

πŸ“Š How do you usually transfer files to SD-map in Redmi 8?
Through the computer
Right on the phone.
Bluetooth/Wi-Fi

The easiest method is to check and issue all the necessary permits manually, which works 80 percent of the time and doesn't require technical knowledge.

  1. Open Settings β†’ Applications β†’ Application Management.
  2. Find the Gallery app (or com.miui.gallery if you are using search).

Cleared gallery cache (Settings) β†’ Warehouse β†’ Clear the cache)-->

If you don't have a system settings change, it's okay. In MIUI 13+, it can be hidden. Instead, try updating the gallery through Google Play (if it's not system-based).

Method 2: Formatting SD-maps as internal memory

This method solves the problem, but it has side effects: once formatted, the map will not be read on other devices (except this smartphone), but all applications, including the gallery, will be fully accessible.

Full access for all applicationsThe card only works on this phone.
Files are encrypted (security)When resetting the phone, the card will have to be formatted again.
Increased internal memory capacityIt is impossible to connect the card to the PC without special software

⚠️ Note: After formatting as internal memory, all data on the map will be deleted. Pre-copy important files to your computer or cloud. Also note that Redmi 8 does not support Adoptable Storage on cards larger than 256 GB - they only have portable storage mode.

What if the internal memory button is inactive?
This problem occurs if: 1. The card has already been formatted internally on another device (you need to format it as portable first). 2. A card with an NTFS/exFAT file system is used (you need to reformat it to FAT32 via a PC). 3. The phone has an informal firmware installed (you need to return the stock MIUI).

Method 3: Using a file manager for manual access

If the gallery stubbornly doesn't see the files, but they're physically on the map, you can temporarily bypass the restrictions through the file manager, which is not a permanent solution, but it can help you copy the photos into internal memory.

Method 4: Reset permissions via ADB (for advanced)

If the standard methods do not help, it remains. ADB-The team that resets all permissions for the gallery app, and it works even when you're in the gallery. MIUI ignores manual settings.

What you need:

  5. Reboot your smartphone.

⚠️ Attention: Teams ADB They give the gallery full read/write rights, which may not be safe. Once the problem is resolved, we recommend that you revoke the permissions: adb shell pm revoke com.miui.gallery android.permission.WRITE_EXTERNAL_STORAGE

What to do if SD-map is not defined at all

  • πŸ”„ File system damage: Connect the card to your PC and check it with chkdsk (Windows) or fsck (Linux/macOS).
  • πŸ”‹ Slot malfunctions: If the card doesn’t work on any device but is read on a PC, the problem is in the micro slot.SD telephone (repair required).
