There is lot of BS going on about saving to the SD card. It is just the fact that some OEM versions of Android CAN use any micro SD card regardless of it's format to be used as "internal", others CAN'T.
It happened to myself - my Xperia Z allows it, Android 4 on an older Galaxy 2 does it, Lenovo Moto with Android 5 can do this and Android 4 on Toshiba AT200 tablets do.
It doesn't work on our two Lenovo tab2 A10-70 tablets and Lenovo C2. But it is not going to tell yu that this not work. Just some missing options in apps - where to store the data - are indicating that the external card can't. And some Android versions do not show up the dialogue what to do with the freshly insered micro SD card when the sd card slot requires a battery removal... mostly the dialogue comes up when it is plugged into a slot while Android is running...
So yu plug in a SD card and a) no dialogue pops up with formatthgin something 2.) yu missed it 3.) yur Android doesn't want it.
There are two solutions:
1.) the Android way:
Some branded Android versions do not do this with fat32 or exfat in case internal data should be stored there.
YOU MUST FORMAT IT FOR INTERNAL USAGE in the settings / storage + usb / details of the external card. Tab on it and there are three options... use "format for internal usage". A warning comes up "all data are deleted". Back it up if there is anything... then hit the OK button. Formatting will take 5 min on a 32 GB card.
Then a dialogue comes up "move data to external storage".
done.
2.) the hardcore way
Android is linux
Linux has a file /etc/mounttab
that is where yu can do some automatical folder redirection.
OR
create an additional startup script for runlevel 5, link this script in the file rc5.d
and in this script yu can use the ln command for folder redirection links, e.g. you can mount /dev/sd1/dcim to /dev/sd0 or use the ln command to accomplish this.
Basically Android can save to all file systems but the menu option where to save does NOT appear in case yu just go to computer store and buy a micro SD. Below 64 GB they come with fat32 and larger they are usually formatted with Exfat.
