Xiaomi Phones: What is it, how to check and why do you need a certificate?

If you've ever bought a Xiaomi smartphone in Russia, you've probably come across the term Rostest, a word that's often found in marketplace descriptions, in salespeople's conversations, and even in warranty repair disputes. But what's really behind this acronym? Why are some phones certified by Rostest and others not? And most importantly, does it affect the quality, legality, or functionality of the device?
