'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
Apple on Wednesday released iOS 15.2.1 and iPadOS 15.2.1 for iPhone and iPad owners. The update comes in at just over 800MB on the 2021 iPad Pro and is currently downloading on my iPhone 13 Pro Max and iPad Pro.
There weren't any release notes available in the Settings app, but there is a support document dealing with the security contents of the update for iPhone and iPad. There's a weird HomeKit bug that bricks your device if you rename a HomeKit accessory with a string of text 500,000 characters long.
According to Apple, iOS 15.2.1 and iPadOS 15.2.1 fixes the issue.
It's not like any of us were naming accessories something a half-million characters long, but there was potential for someone to change the name of a device on your Home app and break your Apple devices in the process.
You can download the update using the normal process of going to Settings > General > Software Update and following the prompts.
