So here's my doubt as in the title. I'm running Danvdh GE-based 4.4.2 ROM, which is almost stock with some small power user customizations. I woudln't complain about it if it wasn't for Google's stubborness to disable the SD card access.
As you can see, it not only seems to be a bug, but the trend. I was coping with it with the hopes they'd find a solution/workaround, but it seems Google's way to go implies disabling your SD card. And I have a 64GB SD card, because I want to keep movies/pictures/backups. I DO want to use it.
My biggest concern is CM's performance when dealing with the camera, as they didn't have access to the Samsung's firmware (and I heard several people mentioning it doesn't perform very well on difficult situations, not to mention broken HDR). Is it possible to replace the stock camera with GE version?
