iOS 27 and Android 17 updates: latest versions, fixes and known issues

This page tracks the current iPhone and Android software versions and links to our fix guides. Every fact comes from Apple Support or Google, and each section shows when it was checked. It is not a rumor page: if something is not in an official release note, it is not here.

iPhone: iOS 27.0.1 (September 28, 2026)

Apple released iOS 27 on September 14, 2026, and iOS 27.0.1 on September 28, 2026. Apple's list of security releases shows iOS 27.0.1 for iPhone 11 and later. Apple's notes for the update say it provides bug fixes and list three:

• iPhone 18 Pro and iPhone 18 Pro Max may unexpectedly restart when Face ID fails to authenticate.
• A color artifact may appear on photos captured at 2x under certain lighting conditions at f/1.48 on a small number of iPhone 18 Pro and Pro Max devices.
• Opening Notification Center and Control Center at the same time may cause the touchscreen to become unresponsive.

If you have an iPhone 18 Pro, see our guide to the iPhone 18 Pro Face ID bug.

What is new in iOS 27

Apple describes iOS 27 as bringing the next generation of Apple Intelligence and Siri AI. Apple's page for the update lists a more conversational Siri with its own app, new parental controls and Screen Time updates, Liquid Glass refinements, better search, and improved Wi-Fi and cellular transitions. Some Siri and Apple Intelligence features need an iPhone 16 or later, or an iPhone 15 Pro or Pro Max, and some are not available in every region. Check Apple's feature availability page for your model.

iOS 26.7.1 for people who have not moved to iOS 27

Apple also released iOS 26.7.1 on September 28, 2026, for iPhone 11 and later. If you are staying on iOS 26 for now, install it. Open Settings › General › Software Update, and if iOS 27 is offered first, look for the option to stay on iOS 26 and install the latest 26 update.

Android: Pixel updates

Google published the October 2026 Pixel Update Bulletin on October 6, 2026. The earlier bulletins this year were published on June 16, July 7, August 4 and September 15. Android 17 began rolling out to Pixel phones in June 2026, according to press reports, which matches the June 16 bulletin date. Updates roll out gradually and depend on your carrier and device, so yours may arrive days after the bulletin.

Google says Pixel 8 and later get 7 years of OS and security updates. Pixel 6 through 7a get 5 years. For other brands, such as Samsung, updates come from the phone maker. See how to update your Android phone for the steps on any Android phone.

Before you update

• Back up your iPhone or Android phone. See our guides to backing up an iPhone and an Android phone.
• Install on Wi-Fi with at least 50% battery, or on a charger.
• Free up some storage first if the update says there is not enough space.
• Do not judge battery life on day one. After a major update the phone does extra work in the background.

Our step by step guide to updating your iPhone covers checking your version, automatic updates and what to do if the update will not show up.

Problems after an iOS 27 update

• Indexing in Progress or Optimizing Search and Siri in Settings, which can take hours to days.
• Battery draining fast, which is common in the first days after a big update.
• Update stuck on Verifying.
• Other problems after an iOS update, such as lag, heat and apps that crash.
• Turning off Liquid Glass effects if the new look is hard to read.
