I own an iPad Air 1 and Air 2. The Air 1 hasn't really crashed in the past year or so. The Air 2 has probably crashed 10 times in the past week. I followed the instructions here: http://www.techgravy.net/check-iphone-6-mlc-tlc-nand-flash-memory/ It turns out I am using TLC flash memory. Perhaps this would explain why I am experiencing random reboots and freezes. I'd like to know how many people are having this issue and what type of memory they are using.
