How to Change Signature Color and Use Arabic in Acrobat for Android
Question details
The user wants to know how to type Arabic text correctly and change the color of electronic signatures in Adobe Acrobat or Fill & Sign on an Android device.

- Product
- Adobe Acrobat Reader
- Device & OS
- Android
- Scenario
- Signing a PDF document and filling out forms using a mobile device in Arabic.
- Observed behavior
- The signature color selection feature is available on iOS but missing on Android. Additionally, text input settings default to Hindi formats instead of correctly supporting Arabic writing.
Ensure your Android device is updated to the latest operating system and that you have installed the most recent version of your PDF reader from the Google Play Store.
Update Android Language Settings and App Version
Ensuring your device's system language and keyboard settings match your desired input can resolve regional text glitches like Arabic text defaulting to Hindi formatting.
Mobile apps often rely on system-level language preferences to render fonts correctly. If Arabic text is not displaying as expected, your device's keyboard or language region settings might need adjustment.
Go to your Android device's 'Settings' app and select 'System' or 'General Management'.
Tap on 'Language & input' and ensure Arabic is added to your preferred languages and active keyboard options.
Open the Google Play Store, search for 'Adobe Acrobat Reader' or 'Adobe Fill & Sign', and tap 'Update' if a newer version is available.
Launch the app and attempt to type in a form field or sign the document to see if the Arabic input and color options have been restored.

Submit Feedback for Missing Signature Colors
If the signature color palette remains unavailable on the Android app while present on iOS, reporting the discrepancy to the developer can help prioritize the feature.

Frequently Asked Questions
Why can I change signature colors in my PDF app on iOS but not on Android?
Feature availability often varies between operating systems due to different development cycles. The signature color selection tool is natively supported in the iOS version of some popular PDF readers, but it may be limited or entirely missing in certain Android builds.
How do I fix Arabic text appearing in a Hindi format in my PDF?
This usually happens when the app defaults to regional rendering settings. Check your Android device's language and keyboard settings, ensure Arabic is set as the primary input, and keep your PDF app updated to the latest version to ensure proper font rendering.
Is there an alternative way to change my signature color on Android?
If your current PDF reader lacks this feature on Android, you can use alternative applications like WPS Office, which provides built-in tools to customize signature colors, stroke sizes, and text annotations directly on your mobile device.
