That was my experience with a Samsung Galaxy S4. MicroSD slot became somewhat unreliable, which led to unreliable functioning of things like music, because I had my music on the SD card. Sadly, I had assumed this would be rock-solid when I bought the phone, so I went with minimum internal memory.
My replacement is a Nexus 6P with 128GB of internal storage. Much happier. Except for the part where I spent something like $739 or thereabouts for the 6P with Nexus Protect.
