Those who take their Samsung Galaxy device to a repair store may get it back in pieces, since Samsung forces service providers under certain conditions to disassemble devices instead of repairing them, and to send the customer's personal data to the company. iFixit is therefore ending its cooperation with Samsung.
Consider this: A person has their iPhone battery replaced with a cheap Chinese 3rd party battery. A month later, the battery catches fire, injuring the person. Which headline do you honestly believe will run:
Apple iPhone catches fire, injures owner.
Unauthorized replacement iPhone battery catches fire, injures owner.
