Hey all - Just purchased a ZTE Sonata 3, on the lure of Marshmallow's ability to mount an SD card as internal storage, upping my internal capacity to my SD's capacity. My device, the brand new ZTE Sonata 3, will only seem to recognise SD cards as portable storage, and shows no option to mount as internal. Furthermore, I can't even seem to relocate any apps to SD, even apps which have capability for external storage. Has anybody dealt with this, or know a workaround? Thank you!
