Update iOS and the Adobe Fill & Sign App
Updating both your operating system and the app ensures you have the latest compatibility patches from the developers for large screen aspect ratios.
Display margins on newer iPhone models often occur because an app has not been optimized for the latest device dimensions. Installing the newest updates generally resolves these scaling and compatibility limits.
Open the Apple App Store, tap your profile icon in the top right corner, scroll down to check for available updates, and tap 'Update' next to Adobe Fill & Sign.
Navigate to the iPhone Settings app, tap 'General', then 'Software Update', and install any pending iOS updates.
Launch the Adobe Fill & Sign app again and rotate your iPhone to test both portrait and landscape viewing modes.
Report the Compatibility Issue to Adobe Support
If updating does not resolve the unused margins, documenting the issue and providing it to support helps developers release a targeted fix.

Frequently Asked Questions
Why do some apps have black bars or unused margins on newer iPhones?
When Apple introduces new screen sizes and resolutions, developers must update their apps to support the new dimensions. If an app lacks this specific update, iOS displays it in its original aspect ratio with black borders to prevent the interface from stretching or distorting.
Can I manually force an app into full-screen mode on iOS?
No, Apple's iOS does not offer a manual override or stretch-to-fit toggle for third-party applications. Fixing the display boundary requires a native update containing the proper resolution assets from the app's developer.
How do I check which version of the Adobe Fill & Sign app I am using?
You can check the app version by opening your iPhone Settings, scrolling down to your list of installed apps, and tapping Adobe Fill & Sign. The version number is typically displayed on that page, or you can view it within the app's internal settings menu.
