FAQ: answers to frequent questions about memory cards in Xiaomi Redmi 6

Can I use a memory card as an internal memory?
Technically, Xiaomi Redmi 6 based on Android 8.1 Oreo supports Adoptable Storage, but officially this option is disabled in the MIUI firmware. To activate it, you will need to: Unlock the bootloader. Install custom recovery (for example, TWRP). Manually edit the firmware files. We do not recommend this for inexperienced users, since there is a risk of turning the smartphone into a brick.
Why did the smartphone become slower after inserting the memory card?
This can happen for two reasons: slow memory card speed. If you use a Class 4 or Class 6 card, read/write speeds will be slow, which will slow down the applications installed on the card; file fragmentation; Over time, files on the memory card fragment, which reduces the speed of access; the solution is to format the card (by pre-copying the data) or use defragmentation utilities (for example, SD Maid).
Can I put two in? SIM-card and memory card simultaneously?
No, Xiaomi Redmi 6 has a hybrid slot that supports either: Two nano-SIM cards, One nano-SIM + One microSD card, if you need two. SIM-card and memory card, consider using Bluetooth headphones (to avoid taking up a slot) or buying a smartphone with a separate microSD slot (such as the Redmi Note 7 or newer).
Which file system should you choose when formatting your card: FAT32 or exFAT?
The choice depends on the size of the card and your tasks: FAT32: Suitable for cards up to 32 GB. Compatible with all devices, but has a file size limit (maximum 4 GB). exFAT: Optimal for cards from 64 GB and above. There are no limits on file size, but some older devices (such as car radios) may not support it. For Redmi 6, it is better to choose exFAT if the card size is more than 32 GB.
What if the memory card is no longer defined after the MIUI update?
Sometimes, after a firmware update, the smartphone stops seeing the memory card, which can be due to: Driver failure, security settings change, Solutions: Reset your smartphone, check the card on another device, format the card (if the data is not important), reset your smartphone to factory settings (Settings โ†’ Additional โ†’ Recovery and Reset). If the problem persists, try rolling back to the previous version of MIUI via Fastboot.
