PDF Preview functionality - how to disable?

Why would you even bother to interfere?

I cant think of a good reason.

You are either a Dropbox employee with an alias or you must gain something for this propaganda.

We obviously have very differing opinions of interfering. I was trying to offer advice on what is a public forum. Of which, you know, people are allowed to have altering opinions to you. You just seem incapable of accepting that. There is no propaganda. There is no underlying agenda. No other reason than trying to help.

I really couldn't care less if the feature is added or it isnt. But for a a third time.... get people to up vote the first one if they want it to change. Prove to Dropbox its an issue. 'cause at the moment it isnt looking that way. Get them as rilled up and charged as they (rightly) are about the atrocity that is recents. 

You're entitled to your little diva-rants and strops and if us posting here gets you that upset and distressed I'd be asking myself 'why'. On all of your "points" you couldnt be further from the truth. 

Never mind. Its your loss. 

I have the same issue the majority of you are having on here and got online just now to try to find a solution.  Its right here and it doesnt look like anyone has tried it.  John B has the answer.  I did exactly as he did and it worked perfectly.  Now the screw up DropBox created is fixed.  Anytime I open a PDF now on my phone, it opens in my phone Office app...no more crappy Dropbox viewer!!! Some goofball in here assumed this didnt work and dismissed it...he was wrong.   John B.May 22, 2016 16:19

Unfortunately when I share a PDF file via a link from Dropbox when the user opens the link the file opens in a viewer that does not support any of the many internal links that are in the PDF document.  Hence the user is getting a stripped down version of a document that we spent a great deal of effort to create.  If the document would only open in a native PDF reader we would be good to go.  Unfortunately, based on the above comments we are forced to look for an alternate solution to deploy documents.

Anyone have recommendations on alternate delivery methods?

go to settings. applications. application manager. dropbox. clear default.

Nope. That only prevents DropBox from acting as a pdf viewer for files outside DropBox (eg. on your SD card). Doesn't change anything on said behaviour.

After waiting a year for this issue to be resolved, I finally switched to google drive last week. It was a great decision for organization and speed.

 I made this account simply to express how deeply I loath the fact that I now cannot use my public directory to link PDFs to my website without Dropbox forcing itself into the process.   Your customers deserve the choice to turn it off.   I really like dropbox - but they are going to lose me as a customer pretty soon.   

----UPDATE-----

I wanted to give credit where credit is due.  When Dropbox first started adding it's own viewer to the process - it was really discouraging because I had built my website for my research around it's previous simplier (frankly less intrusive) approach.   BUT! Dropbox did fix it ( a while ago too) and I am happy I was able to stay with the service.  the dl=0 vs dl=1 option at the end of the links makes it feasible for me to continue to use dropbox to distribute information to collegues and now allowed me to use PDFs in my personal research more easily.  

Cheers Dropbox and thanks for the fix. 

FWIW, i also have an Anchor (syncedtool) account and I love it.   You can actually customize the entire experience and I was able to disable file preview.   I hope that dropbox follows suit and allows disabling previews...i keep getting emails daily from customers saying "the file doesn't open" simply because there is javascript in the html and they expect the preview to display correctly (this is for small simply HTML-based file listings).  I have to constantly tell them to DOWNLOAD the HTML file, then open it on their device...very annoying.
