I must retract my previous criticism of the Redmi brand; it turns out that it was enough to change the manufacturer's software to a more regionally compatible version in a relatively simple way for the device to fully regain its responsiveness and stability. The previously mentioned shortcomings do not occur in the latest version of the manufacturer's interface. An added value of this brand is undoubtedly the software support and the number of device software updates. This comment is written after a year of using this device.
