How to block spam calls using iOS 13’s silence unknown callers feature

Telemarketing and robocalling have run rampant this year, and these annoying calls are a nuisance that takes time out of your busy day. While mobile carriers and even the government work to deter these calls, there’s something you can do right now to put a stop to obnoxious spam calls.

Apple’s latest iOS includes a feature that will send unknown callers straight to your voicemail; we’ll show you how to use it right here.

  1. Make sure you have iOS 13 by heading to the Settings app and tapping through to General > Software Update.
  2. Head to the Settings app again, and tap on Phone.
  3. Toggle on the Silence Unknown Callers toggle.

With this feature activated, unknown callers will automatically be sent to voicemail, meaning that spam calls, robocalls, and other unwanted distractions will no longer be able to bother you. If you’re like me, you likely get at least a few spam calls every day — meaning that this feature could save both time and energy.

The feature actually does a little more than simply screen calls and blocked numbers. According to Apple, the feature uses artificial intelligence to detect phone numbers in your Mail and Messages app — not just in contacts. What that does is ensure that people you know can still get through, even if they’re not in your contacts list. Hopefully, the feature will ensure that you never miss a call that you shouldn’t miss, but still manage to block calls that aren’t relevant to you.

It’s unlikely, however, that the new system will be perfect. Spam callers regularly find new ways to get through to their victims, so we wouldn’t be surprised to see them find new ways to disguise their numbers. Not only that, but it’s likely that you will, at some point, unintentionally block a call without meaning to, so it’s worth keeping an eye on your voicemails and call log. If this handy feature doesn’t do the trick for you, then check out our guide on how to block a number for more options.

How to use iOS 18 FaceTime gestures (and what they look like)
Video reactions in macOS Sonoma, with the balloons effect in use.

Apple iOS 17 brought FaceTime gestures to the iPhone last year, livening up the FaceTime experience for all users. FaceTime gestures are even more useful now with iOS 18 and Apple Intelligence. Once it’s set up correctly, you’ll be able to send 3D animations to your friends and family during FaceTime video calls. You’ll even be able to trigger the animations with physical gestures.

Getting your phone ready for action doesn’t take much time or effort, but we put this guide together to walk you through the process nonetheless.

A hidden iOS 18.1 upgrade made it harder to extract data from iPhones

Apple Intelligence was the most notable upgrade that arrived on iPhones with the iOS 18 series of updates. But it seems Apple reinforced the security protocols in the background that could prevent bad actors from gaining unauthorized access to iPhones that haven’t been unlocked in a while by their legitimate owner.

Earlier this month, 404Media reported that law enforcement officials are troubled by iPhones that are mysteriously rebooting. Citing a report courtesy of officials in Michigan, the outlet notes that the reboots are hampering the ability to access what’s stored on the phones through brute-force unlock methods.

Apple quietly nixed this Apple Intelligence feature from iOS 18.2
Image Playground on iPad.

One of the most highly anticipated features of Apple Intelligence, Image Playground, has finally launched in the iOS 18.2 developer and public betas. This artificial intelligence tool, announced in June, enables users to create cartoon-like images from text descriptions. Unfortunately, at least in the beta version, one of Image Playground's announced features is missing.

As first noted on X (formerly Twitter) by @nicolas09f9 (via MacRumors), Image Playground was once expected to feature three design styles: Animation, Illustration, and Sketch. For whatever reason, the latter isn't a choice in the beta.
