Step-by-step explanation:
To open PDF files on a Samsung phone, you will typically use the Adobe Acrobat Reader app, which is a popular and widely used PDF reader. You can download it for free from the Go-ogle Play Store. Once installed, you can open PDF files by tapping on them in your file manager or directly through the Adobe Acrobat Reader app.
Many Samsung phones also come with a built-in PDF reader within the My Files app, so you may not need an additional app. Simply tap on the PDF file, and it should open in the default viewer. If you have multiple PDF viewer apps, your phone might prompt you to select which app you would like to use to open the PDF file.
