Ensure your Samsung Galaxy J7 is connected to the internet to download the necessary applications from the Google Play Store, and verify that the target PDF file is saved in your device's local storage.
Use the Adobe Fill & Sign App for Android
Adobe Fill & Sign is a dedicated application specifically optimized for filling out forms and adding signatures directly from your mobile screen.
While Adobe Acrobat Reader can open and view PDF files, the Adobe Fill & Sign application provides a streamlined interface specifically tailored for form filling and digital signatures without requiring complex editing menus.
Open the Google Play Store on your Samsung Galaxy J7, search for 'Adobe Fill & Sign', and install the free application.
Launch the Adobe Fill & Sign app, tap the 'Select a form to fill out' icon in the center of the screen, and navigate to the PDF file saved on your phone.
Tap anywhere on the document where you need to input text. The app will create a text box, allowing you to type your information directly onto the form lines.
Tap the pen icon at the top of the screen. Select 'Create Signature' to draw your signature using your finger, then tap 'Done'. Tap the pen icon again to place the signature into the document and drag it to the correct location.
Once the form is complete, tap the 'Share' icon (three connected dots) at the top of the screen and choose your preferred email app (like Gmail or Outlook) to send the signed PDF as an attachment.

Fill and Sign PDFs Effortlessly with WPS Office
If you prefer not to download multiple specialized apps, WPS Office provides a powerful, all-in-one solution for your Samsung Galaxy J7. It allows you to open, fill, sign, and instantly share PDFs natively alongside your Word, Excel, and PowerPoint documents.

Frequently Asked Questions
Can I use Adobe Acrobat Reader instead of Adobe Fill & Sign on my Android phone?
Yes. Adobe Acrobat Reader for Android has a built-in 'Fill & Sign' feature located in the tools menu. However, the standalone Adobe Fill & Sign app provides a faster, distraction-free interface if your only goal is to complete a form.
Do I have to pay to use the fill and sign features on my mobile device?
No, filling out standard PDF forms and adding a hand-drawn signature are free features in both the Adobe Fill & Sign app and WPS Office for Android. You do not need a premium subscription for these basic tasks.
Why can't I edit the original text of the PDF in the Fill & Sign app?
The Fill & Sign tool is explicitly designed to overlay new text, checkmarks, and signatures onto an existing file without altering its original layout. If you need to modify the original underlying text, you will need a full PDF editor like WPS Office Premium.
How do I ensure the receiver can't edit my signature after I email it?
When you share a PDF using the Fill & Sign feature in Adobe or WPS Office, the document is typically flattened before it is emailed. This means your signature and added text are merged into the image of the document, making it difficult for the recipient to alter.
