Since you configured sd as "internal", can't use it in other device until revert type of usage. You can access to it connecting the smartphone to a pc.
In my g620s-L01, Sygic crashes since start. Rest is OK. Detects perfectly my microsd of 64Gb.
Installed without problems from philztouch recovery by Eloygomez.
I think it's Letine LT907B model.
