What I like least about Lenovo, along with Xiaomi, is their updates. A tablet that's used less than a mobile phone should have at least six operating system updates, like Samsung does. Chinese tablets only get three to four years of updates, so over time they lose their value and performance, preventing them from utilizing the full potential of the operating system, as is the case with Samsung.
There should be a law requiring all tablets to have at least six years of operating system updates, at least in the mid-range and high-end ranges.
