Hello, I've heard that one of the big features of marshmallow was the possibility to extend the internal storage by crypting the micro-SD. So I bought a New Class 10 SD to solve my short memory problem (16Go, rather 10Go encumbered by 5,6Go of system...) but I can't find this option, not were it should be accorded to some "tutorial". Does anyone know how to solve this ? Thank you very much ! PS: Sorry if my english is bad i'm not a native speaker.
