A lot of people including me that own a Xiaomi RedMi 6 lost data on SDs used in this phone. Seems this happened last 2 or 3 updates - SD cards went to RAW and even some of them cannot be successfully read. Bye-bye pictures or everything stored during normal usage and not backed-up/synced ...
Current version of the device:
Model number: Redmi 6
Android version: 8.1.O11019
Android security patch level: 2019-03-01
MIUI version: MIUI Global 10.2 | Stable 10.2.6.0 (OCGMIXM)
Model name: M1804C3DG
Baseband version: MOLY.R12A.R2.MP.V24.32.P122
Kernel version: 4.9.77+
Is there an official anwser from Xiaomi how to fix this?
