Phone Won't Update to the Latest iOS or Android — Fix It
Software updates stuck downloading, failing to install, or simply not appearing are common headaches. Here's what's actually happening and how to get the update to complete.

Software update problems usually have mundane causes: not enough storage, a poor Wi-Fi connection, or a server being temporarily busy. The good news is most of these fix themselves with a few targeted steps.
Check Whether Your Phone Supports the Update
Not all phones can run the latest version of iOS or Android — Apple and Google both drop support for older models. If the update simply doesn't appear, your phone may have reached the end of its supported lifespan for that particular OS version. On iPhone, check Apple's support pages for which iOS version your model supports. On Android, it varies by manufacturer.
Free Up Enough Storage
iOS updates typically need 3–6 GB of free space; Android updates vary but often need 2–4 GB. Check your current free space:
- iPhone: Settings → General → iPhone Storage
- Android: Settings → Storage
Delete photos, cached content, or unused apps until you have enough room.
Connect to Wi-Fi
Large updates won't download over mobile data by default. Make sure you're connected to Wi-Fi with a strong signal, and keep the phone connected during the entire download and install — switching networks mid-download can corrupt the file.
Restart the Phone and Try Again
If the update is stuck downloading or shows an error, restart the phone, reconnect to Wi-Fi, and go back to the update screen. The download often resumes or restarts cleanly.
Delete the Partial Download (iPhone)
\p>- Go to Settings → General → iPhone Storage.
- Look for an entry called iOS [version number] in the app list.
- Tap it and choose Delete Update.
- Go back to Settings → General → Software Update and download it again from scratch.
Update via a Computer (iPhone)
If the over-the-air update keeps failing, updating via a computer is more reliable. Connect your iPhone to a Mac running Finder, or a Windows PC running Apple Devices (or iTunes). Select your phone and click Check for Update, then Update. The computer downloads the full installer file, which is more stable than the wireless method.
Android: Check Manufacturer Update App
Samsung updates go through Settings → Software update → Download and install. On Pixel phones, it's Settings → System → System update. If updates aren't appearing, try tapping Check for update manually rather than waiting for automatic notification.
If an update installs but the phone is stuck on a loading screen afterwards, a force restart usually gets it moving. Ask us if you're stuck at any specific step.
Frequently asked questions
My iPhone says 'Software Update Failed — An error occurred downloading iOS.' What should I do?
First, delete the partial update from Settings → General → iPhone Storage, then restart the phone and try downloading again on a different Wi-Fi network. If it keeps failing, use a computer to update via Finder (Mac) or Apple Devices (Windows) instead — the computer downloads the full installer file independently, which bypasses the over-the-air error.
Android says my phone is up to date, but I know a newer version was released. Why can't I get it?
Android updates are rolled out in stages, and carriers sometimes add further delays for testing. Your phone may simply be waiting in the queue for your region or carrier. Check back in a few days. If your manufacturer stopped supporting your model, the update may never arrive — in that case, the only path to a newer Android version is a new phone or (on some models) an unofficial custom ROM, which is an advanced option.
