Hello. Wishing to ask about OTG on Nokia 2.1. The thing is that my 64gb Sandisk Ultra microSD card, having been previously inserted on my Microsoft Lumia 550, needed formatting if I were to use it on the Nokia 2.1's card slot. Now, if I were to use an OTG USB card reader on the 2.1, can I finally view my microSD files on the 2.1, or do I still need to format? Thanks.
