I am noticing something those devices have in common.

My Galaxy Tab also has dead EMMC. My HTC One M8 still works and even holds a day of charge. Too bad Android doesn't support 32bit ARM anymore.

It can also depend on the hardware it's connected to. If the endless gigabytes of Samsung's value-add software are scribbling to eMMC nonstop then it's not surprising the flash is wearing out. A lot of this stuff is masked by the fact that most people swap out their phone for a new one that's exactly the same every 12 months so they never notice this, but if you hold onto a phone or similar device for longer the unnecessary wear starts to add up.

		Google Android should get more praise for doing quality control by analyzing and killing apps and processes that attacked the hardware - at least back in the day. The great filter for incompetence by the big G was real and necessary.
