well i have a galaxy s4, and I just found out today that it can hold up to a 64 gb micro sd card in it. I used my s4 to hack my n3ds, and I use it to put emulator games and .3ds roms on it for conversion. well, I know it would be cool if I could get a 128 gb card for my 3ds but hey oh well right. so I was thinking this: I have 2 android phones, the other is a crappy pixie touch ($10 android phone brand new... yeah it sucks), that can read up to a 32gb card. so I was going to get the 64 gb card, and Bluetooth everything from the smaller card on my crappy phone, onto the s4 with the bigger card in it. and if any of you ask, no I don't have a pc, and don't have access to one either. would this be safe?? anyone ever switched to a bigger card in your 3ds??
