Max SD Card Size For Note Edge I have a 16 GB SD Card in my Galaxy Note Edge and only have 1GB of storage left.  I read that some Android devices can only hold up to 32GB - can my phone support the 64GB card?
Yes

Galaxy Note Edge SM-915G user manual says


  Your device accepts memory card with a maximum capacity of 128 GB


Also in this review (S6 Edge+ does NOT)


  Samsung does offer a 128GB option for its Galaxy S6 and Galaxy S6 Edge
