When browser tools aren't enough — particularly for annotation, form filling, and document management — these Play Store apps are worth considering. Adobe Acrobat Reader (free + subscription): The free tier is generous and handles most reading, form filling, and basic annotation needs. The subscription ($19.99/month) adds text editing, export to Word/Excel, and Adobe Sign. For most tablet users, the free tier is all they need. Available from Play Store; excellent Samsung Galaxy Tab S Pen support. Microsoft Office (free with limitations): If you have a Microsoft 365 subscription, the Word app on Android can open and edit PDFs. This is particularly useful for converting PDFs to editable Word format — a feature that's otherwise paywalled in most PDF apps. The free tier has limitations but works for viewing and light editing. Xodo PDF Reader & Editor (free): One of the most feature-complete free PDF apps on Android. Annotation, form filling, signature, split and merge (with some limits), and cloud integration. No subscription required for core features. A solid choice for users who want an app-based experience without paying. WPS Office (free): Handles PDFs alongside Office formats. Good for users who regularly work across document types. Free tier includes PDF viewing and annotation. The PDF merge feature in the free tier has page limits but covers most casual use cases.

Samsung Galaxy Tab S series tablets offer some PDF-specific advantages over generic Android tablets that are worth knowing about. S Pen integration: The S Pen stylus provides 4,096 levels of pressure sensitivity, making handwritten PDF annotation feel natural. Adobe Acrobat Reader and Xodo both support S Pen beautifully. The S Pen also enables Air Actions (hover over a page to preview, press the S Pen button to navigate) that speed up document review. Samsung DeX: Connecting a Galaxy Tab to an external monitor via DeX mode enables a desktop-like PDF workflow with resizable windows, precise mouse/trackpad control for browser tools, and the ability to run multiple apps side by side. For users who use their Galaxy Tab as a laptop replacement, DeX makes browser-based tools like LazyPDF significantly more productive. Samsung Notes PDF integration: Samsung Notes can open PDFs directly and annotate them with S Pen, with excellent handwriting recognition and multi-page management. For Samsung tablet users who already use Samsung Notes for other work, this built-in option is convenient. Samsung My Files: Samsung's file manager has better PDF thumbnail generation than stock Android, making it easier to identify the right document when managing a large PDF library.

Not every highly-rated Play Store PDF app delivers on its promise. Here are common categories to be cautious about. Apps that claim 'free' but paywall all useful features: Many apps in the 'PDF editor' category on Play Store have 4+ star ratings because they rate-bait users before the paywall kicks in. If an app requires payment to download a processed PDF (after letting you preview it), look elsewhere — free browser tools deliver the full result without holding files hostage. Apps with excessive permissions: Some PDF apps request access to contacts, camera, microphone, and all files on your device. A PDF merging or compression tool has no legitimate need for contacts or microphone access. Be suspicious of apps that request permissions unrelated to their stated function. Converter apps that route files through unknown servers: Some 'PDF converter' apps send your documents to unknown servers in regions with poor data privacy regulations. For sensitive documents, stick to tools that are transparent about their data handling — or use browser-based tools where the processing is done by the tool provider's disclosed servers. The safest approach: use browser-based tools (transparent, no app permissions required) for structural PDF editing, and use well-known apps like Adobe Acrobat Reader or Xodo for annotation and viewing.
