There are three parts to this thread - my experience with a 64GB microSDXC memory card, some important notes and the first post in what I hope will be an ongoing guide to the 64GB+ microSDXC memory cards that have been confirmed (or not!) to work with the Xperia Z...
My Experience
Okay, despite Sony Mobile claiming that the largest memory card supported by the Xperia Z is a 32GB microSD, a lot of people in a lot of places online are claiming otherwise... So I held my breath and decided to try it out for myself.
With a fresh (just bought) 64GB microSDXC memory card, I pulled it out of the packet and inserted it into my fully powered-up Xperia Z, at which point there was an error message in the status area (at the very top of the screen) stating that the memory card was either blank, or used an un-supported file system (I should have taken a screen-shot, but I didn't think of it at the time).
Leaving the error message in the status area (i.e. I did not "swipe" it away or click it), I first I tried to mount and format the memory card via settings, however my Xperia Z simply refused to mount the memory card or format it via this method... But when I clicked the error message at the top of the screen, I was immediately asked if I wanted to format the memory card, which I preceded to do.
Of course the very first thing I did after this was check the "Storage" menu (Settings-->Storage-->SD Card)... And sure enough, I now have a fully functioning, 64GB microSDXC memory card!
Some important notes!
* I should point-out that some people say they've had problems with SanDisk memory cards because they are significantly thinner than those from most other manufacturers - one theory that has been put forth is that perhaps the thickness of the memory card is causing it to loose contact with the pins inside the Xperia Z (which if you ask me, makes a lot of sense)? In saying this however, there are others that claim they?ve had no problems with SanDisk memory cards.
* Also be aware that most stores (online and offline) won't refund or exchange memory cards simply because they don't work in your chosen device - this is especially true when your device manufacturer has clearly indicated that such a card is not compatible (as is the case with Sony Mobile)... You should be right, but you will be purchasing a microSDXC memory card at your own risk.
* In theory, microSDXC cards larger than 64GB should work... However I have not seen anyone claiming to have tested this - most likely because microSDXC memory cards larger than 64GB are expensive and the price goes up enormously with each capacity/size increment (it's a lot of money to spend if it doesn't work...) - but on paper it should work (and hey - if you're happy to spend huge amounts of money testing this, be sure to let us know how you went!).
What Cards Work?
Now to the final part of this thread - what cards actually work?
Some people say this brand/model works, others say that brand/model works... So let's compile a list of memory cards that people have confirmed as working (or not)!
Remember to include...
* Capacity/Size (e.g. ?64GB?)
* Speed (e.g. ?Class 10?)
* Make/Model (e.g. ?Lexar?)
* Xperia Z Variant (?C6602? or ?C6603? ? found in Settings-->About phone-->Model number)
* Android Version (found in Settings-->About phone-->Android version)
* Any other information that may be relevant or helpful.
If all goes to plan, Xperia Z users looking to purchase a 64GB+ memory card will be able to turn to this list.
I am using?
* Capacity/Size: 64GB
* Speed: Class 10
* Make/Model: Lexar
* Xperia Z Variant: C6603
* Android Version: 4.1.2
