Morphology

flaky = flake (semi-transparent) = flake + y

The adjectival sense 'unreliable' extends from the informal human sense of 'flake' (unreliable person); this extension to inanimate systems is idiomatic and not transparently predictable from the literal noun.

Etymology

Flaky meaning 'not reliable' comes from the same idea of a flake as a loose or light piece that can fall away, like loose paint or a weak connection. That's why we call tests, phones, or systems flaky when they fail or change without warning.
