Here are some things you can try:

Basic checks:

• Make sure your iPhone is connected to a stable Wi-Fi network. A weak or intermittent connection can cause update issues.
• Ensure your iPhone has enough storage space. The update might not be able to download if your storage is full. Go to Settings > General > [Device name] Storage and see how much space you have available. If you need to free up space, delete unnecessary apps or files.
• Force restart your iPhone. This can clear any temporary glitches that might be causing the problem. For an iPhone 7, press and hold the Sleep/Wake button and the Volume Down button simultaneously until you see the Apple logo.
• Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
