The phone fits fine in my front pants pocket, jeans or dress pants.
I use a SanDisk Class 10 64Gb card, now $55 at Amazon (I think I got mine on sale for around $46): Amazon.com: SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-064G-AFFP-A): Electronics I've read several posts of people having problems with the 32GB size, but I've had no problems with the 64.
My understanding is that apps cannot be installed to the external SD card. Whether app data could be stored there I don't know, it may depend on the app. I've set the camera to store photos on the external card.
