If you ever need to get your Touch ID-enabled home button repaired, be sure to have it done by Apple Authorized Service Providers or Apple directly only: UK newspaper The Guardian reports that "thousands" of users who have had their Touch ID button repaired by third parties and found that their iPhone would then "brick" itself (become inoperative) after the next iOS update. The notorious "Error 53" that causes this, according to Apple, is a security measure to prevent low-level hardware hacking.
