Serious issue - hyperlink page destinations not working on phone

Hello,

Serious issue here, I have made an interactive PDF via InDesign - I have used hyperlinks to link a couple graphics to go to different pages in the same document.

eg. (click here to go to pg 5) etc

All other web links etc work fine, however the internal page hyperlinks do not work on the phone. (I am using a Samsung Android)

In InDesign I selected Type > Hyperlinks & Cross References > New Hyperlink > Link to page

Please get back to me asap.

Thank you

G
