Apple enlists Siri in fight against malicious message bug that crashes iPhones

If you receive a lot of text messages from different people, the next few days could have you a little nervous. Though the method of its discovery is unknown, enterprising pranksters have found a string of characters that, when viewed on an iPhone, can lock users out of the Messages app or even crash the phone.

Users who view the string within the Messages app won’t be able to view other conversations without leaving the app, which causes it to crash. Once they’ve exited the app, they likely won’t be able to reopen it. Viewing the message on the lock screen also prevents users from opening the Messages app.

Luckily, Apple has revealed a workaround to free your phone from the bug. Affected iPhone users should ask Siri to “read unread messages,” and then ask Siri to send a reply to the message. Once you’ve responded to the offending message, you should be able to open the app and swipe left to delete to the message thread or just the message itself. Apple told ABC News that it’s working on resolving the issue with a software update.

It’s certainly a good thing that Apple has this workaround in the meantime. A quick Twitter search reveals that plenty of users were affected by this “prank” within just 24 hours. We won’t share the specific characters here, but it is essentially impossible to enter the string in question by accident, so if you receive this message, it’s because someone sent it to you on purpose.

This isn’t the first time that a bug like this has been seen in the wild, 9to5Mac notes, and Apple is usually quick to fix such bugs, but it will likely be a while before a fix is available. Luckily, there are a few ways to regain control of your phone if you happen to be affected.

If the person who sent you the mischievous message is actually a friend (if perhaps not a very mature one), having them send any other message will free up the Messages app to be used again — and may go some way toward repairing the friendship as well. Replying to the Message using Siri or the built-in iOS share functionality will also work.

If you’re one of the unlucky bunch whose phone has crashed, it may be easiest to reply to the Message via the Mac version of the Messages app, which isn’t affected by the bug.

It isn’t clear how long this bug has been quietly festering, but now that it is out in the open, this will likely get worse before it gets better. Stay safe out there.

The iPhone 17 will reportedly get a new type of Wi-Fi chip

A person using the Apple iPhone 16 Plus.

By this time next year, Apple may have installed its own in-house Wi-Fi chips in all of its phones, or at least one of them.

According to Ming-Chi Kuo, a well-known analyst with a trusted record, Apple is working on its own Wi-Fi chips to replace the current ones from Broadcom, but there's not a firm timeline on when they'll arrive (via MacRumors). He says the iPhone 17 Pro might come equipped with this new chip, but other sources suggest it won't get widespread adoption until the iPhone 18.

How to fast charge your iPhone

iPhone 12 Mini with charger

While they may not be some of the longest-lasting smartphones on the market, modern iPhones boast more than respectable battery life that should be able to get you through an entire day's use without breaking too much of a sweat. Of course, that assumes a lot of things — including a battery that's still relatively new and in good health, plus a usage pattern that doesn't include all-day streaming or gaming.

But for some people, overnight charging isn't going to cut it, and you'll want to get your battery topped up again as quickly as you can so you can get back in action. Thankfully, every iPhone released in the past six years supports much faster charging, but the downside is that with very few exceptions, Apple has never supplied you with the right adapter to get the best possible charging speeds from your iPhone.

5 phones you should buy instead of the iPhone 16

Someone holding the iPhone 16.

Apple’s iPhone 16 has arrived, and it’s quite an impressive offering this year. Not only does it come in some of the best colors we’ve seen in a while, but it closes the gap between the base and Pro models even more.

That's all to say the iPhone 16 is a fantastic phone, but if you’re thinking about buying it as your next smartphone purchase, you should also consider some of these alternatives.
