This adds to Samsung's long covered up history of phones that kill SDcards, bloated batteries, uncompliant USB spec connections, under-specced voltage regulators throughout, cheap USB chargers suspected as built to fail, screen colour imperfections and second hand parts discovered in new phones discovered during new phone tear downs. They regularly spend so much more money on advertising on bus stops and trains than they ever have on r&d for any product. The parts they sell to other vendors for rebranding etc... are almost always custom, higher grade built to order parts, for example their nvme pcie drives sold to Apple are built to much higher standards and they run completely custom Apple firmware, and guess what? They don't fail or fire.

Samsung are a straight out dodgy company - they're the Microsoft of hardware but with better advertising, unfortunately targeted towards people of slightly lower social status often.
