Frequently asked questions
What happens if I update my phone's OS and an app stops working?
When a major OS update ships, apps that haven't been updated to match the new API level can crash, lose functionality, or be removed from the store entirely. You can often roll back an OS update within a short window (varies by manufacturer), or wait for the app developer to release a compatible version — usually within a few weeks of a major release.
How do I know if my device is compatible with a new iOS or Android update?
Apple publishes a supported-device list for each iOS release; look for your iPhone or iPad model in the iOS release notes. Google's Android update policy varies by manufacturer — flagship devices typically receive 3–7 years of updates, while budget devices may only receive 1–2. Your device's Settings > Software Update will only offer updates your manufacturer has certified.
Can older apps run on newer operating systems?
Usually yes, but with caveats. iOS drops support for 32-bit apps from iOS 11 onwards. Android 64-bit requirements (from Android 13) mean old 32-bit-only APKs stop working. macOS has removed 32-bit app support since Catalina. If an app hasn't been updated in several years, check the developer's last release date against your OS version before upgrading.
Why does an app work on one iPhone model but not another of the same iOS version?
Some apps require specific hardware features — Face ID, LiDAR, specific Bluetooth LE profiles, or a minimum A-series chip. Even if two phones share the same iOS version, hardware capability differences can determine whether an app installs or functions correctly.
