Was the Sony Xperia Z3 smartphone tested with the largest microSDXC 200 GB card (Item # SDSDQUAN-200G, product number SDSDQUAN-200G-G4A)?
The smartphone has model number D6603 and is under Android Lollipop 5.1.1, Sony branded.
In general, all the smartphones I have checked are compatible with SDXC cards not larger than 128 GB, so the question is if and how they will cooperate with this large card.
At present I have SanDisk Ultra 128 GB and it works perfectly.
