Probably it has bad sectors and damaged areas and that's why you weren't able to use the dd image for 64GB despite your card is in fact a 64GB one. Try it to do a full formatting of the card with SD-formatter and if the problem persists, you should get a new one, Sandisk or Samsung preferably and at least class 10 speed.
It's a brand new card, literally just out of the packet. I performed a full scan, no errors. Capacities of cards vary depending on the brand, it wasn't by much but this card was slightly under the image size so that's why it wouldn't work.
After reading more I suspect this is the random transfers issue, these SanDisk Ultra cards just don't seem suited for that. I'll verify in Ubuntu when I get the chance. It's a shame the PINE documentation isn't a bit more helpful in this respect, I've ended up buying this SanDisk for nothing. They should be keeping a recommended list of cards, not just saying "buy a class 10".
There are tons of counterfeits Sandisk cards out there, so unless you bought it from a reputable seller, chances are you have a fake one. In the past I even bought a Sandisk ultra from Amazon uk which I later verified it was fake with the help of application ''SD insight'' !
I now solely use ''SanDisk 16GB U3 Extremes'' which work flawlessly while the community recommends Samsung EVO+. I think whichever you buy you will be on the safe side.
The point here is that you should not worry about your Pine64's performance on Android. The experience you had so far has certainly nothing to do with the board's normal performance.
