the S7 has a known issue with sd cards. the phone will constantly display a notification "for transferring photos and media". you can clear it but it will return upon reboot and at times it can reappear randomly for no reason. it does not affect the use. it's just annoying. I along with others have brought this issue up to samsung. they are aware of it. I was told it would be fixed it the next update. hope it's sooner then later.
when I ask same issue to Samsung, they answered that SD card notification pop up which occurred every rebooting will be removed if you clear notification from next software update.
