About this app

********************************************************
Problem:
--------------
Please note that Samsung's "My Files" file browser has a known bug and does not open STL files directly in the app because it fails to associate the STL extension with the right app.

Solution:
--------------
Install any other third party file manager from the Google Play Store to be able to open STL files directly while browsing.

Ratings and reviews

Viewer is great, but doesn't associate file types in the phone's OS. Any time I click on a file to open, it sends me back to the google play store. Instead, I have to open the app and navigate to the file location. This is particularly annoying as a rural user because I'm often out of coverage and the play store won't load. Makes comparing multiple files a significant PITA.

Works as desired BUT has a real bug. If you delete a file you were looking at while the app is closed, when you come back to the app you will not longer be able to navigate to any files. The ... icon will NOT take you back to the root directory. The ONLY way to fix is to reset & clear the apps data. **UPDATE: update 1.92 seems to resolve the issue.**

Updated: confirmed bug is with Samsung My Files app. (opening with Android's built in file picker works fine. + 1 star back. :) only thing left is normals. (thank you for the reply by the way) Previous: Can't select a file from a file manager and open with this app. Must start with this app and browse to the file using it's "open file" option. would be great if it 1. registered as an app for the file extension supported and 2. showed vectors so you can tell where overhangs are for example.
