I'd like a phone, preferably Android, with 256 GB of storage.
To the best of my knowledge, no 256 GB microSD cards exist (despite a few scammy Amazon listings). Therefore, the phone would either need to have (1) a fullsize SD slot or (2) dual microSD slots. I don't know of any android phones that have a fullsize SD slot, although there are of course tablets that do. And the only Android phone I know that promised dual microSD cards is the vaporware Saygus V2.
Do any solutions exist that don't involve solder or external devices?
