Device plagued by bugs since purchase. The reset recommended by Xiaomi a few weeks ago was catastrophic: impossible to save due to lack of space. Since then, it's been impossible to restore, and not only have the bugs persisted (it's impossible to validate a recovered security code, the page systematically disappears and the application returns to the initial page), but they've got worse: the keyboard regularly derails or even locks up!

After 6 months of use, the artcile showed bugs, I sent it back because it was still under warranty, a reset was done but it still didn't work. Now that the warranty has expired, there's nothing I can do except buy another one;;;;;
