After downloading the required app from the app store i plugged in a generic microsd card into the card reader on an iphone 6 and… nothing

I could see the internal device storage and readwrite to a folder i created on the iphone and i could allow access to other folders on the local iphone storage but i couldn’t see or access anything on the sd microsd card via the card reader

I thought here we go again but decided to do some more testing before assuming the worst

The generic cards were using the fat file system the same as the sandisk cards were and performed fine in my other devices but something was clearly different

I reformatted one of the generic sd cards fat32 and then installed it in my camera automatically adding the canon file system and then tried it in the card reader again

For whatever reason some of the generic cards though formatted fat need to be reformatted again before they will work on this card reader

I didn’t check to see if they were formatted fat16 from the factory vs fat32 but reformatting them from a computer seems to fix the issue of generic sd and microsd cards not being usable with this device

Initially i was only looking for a sd to lightning adapter
