Android's January security patch is out, and it's addressing one of the nastiest Android bugs to come up in some time: certain apps can stop you from contacting 911 or other worldwide emergency services numbers.

In early December, a harrowing tale popped up in the GooglePixel subreddit from a user whose Pixel 3 crashed when they needed it most: while dialing 911 for their grandmother who "appeared to be having a stroke." The whole phone subsystem seemed to immediately crash upon calling emergency services, with user "KitchenPicture5849" saying they couldn't get the call to connect or hang up to try the call again. Luckily, a nearby landline was available after their Android phone let them down, and emergency services was able to be contacted.
