– How to open a pdf file from Galaxy Tab?

 
Basically Galaxy tab will need an app to open  PDF file. Period! It is not a Kindle Fire which will open a PDF file automatically.

The simple way is setting a default app to open  a PDF file so that you can save couple steps to open.

Click the checkbox (Use by default for this action) and select the Amazon Kindle.

Next time when you open a PDF file, you will not get the  dialog box for selection of PDF app anymore.
