Judging by the reports on the Web, the owners of Xiaomi, Redmi and Poco smartphones should not rush to update the firmware, because now there are more and more reports of an unexpected problem when installing the latest versions of MIUI 12. Some smartphones fall into an endless reboot cycle, which can be exited in the most difficult cases possible only by resetting to factory settings with the loss of all data. One of the owners of the recently launched Poco X3 NFC demonstrated the problem.
