I have Lenovo Tab3 (LenovoPad TB3-850F, Android 6.0 Marshmallow) and SD (64 GB, UHS1) connected as internal storage (part of total memory). The storage shows me the occupied capacity of the internal memory and SD separately, but using the file manager I do not have the ability to ´manually data copy data to SD, they are stored in internal memory (installed applications are on SD - unfortunately I can not choose to save photos or videos on SD , they are stored in internal; anyway, if I want to copy or download some files, I can't choose as SD storage, the system stores them in internal). Of course - the internal memory is smaller than SD, so I have quite a limited capacity - especially for recorded videos and downloaded videos. And the questions: 1. is it possible to achieve direct access to SD on Marshmallow at all when installing it as internal? 2. is it only possible with some FileManagers? - whom? 3. or will ´root´ help? 4. Or will nothing help? I need the card as internal, because the applications I use only do not fit into the internal (16 GB). Thanks in advance for relevant more experienced answers.
