sd card reader is smoking?

[rocket2nfinity]

the funniest thing is that both card reader and sd card seem to be functional. at least reader managed to read another sd card without setting it on fire, and the first sd card is readable by another card reader. i will dissassemble my pinephone and check for any defects ASAP. Not sure how could they survive such an accident without damage

A direct short from V+ to ground could heat the metal and plastic without neccesarily damaging the card circuitry. It's a good way to kill your battery though, and a sign something is loose or otherwise not right.
