Why are my photos being duplicated in a different aspect ratio?

[Hugo Silva]

When transferring photos to Dropbox from the iPhone, it duplicates the photos, changing the 16:9 format to the 4:3 format. What is happening?

Hi @Hugo Silva, thanks for bringing this to our attention.

Are you using the camera uploads feature, or are you uploading files manually to your Dropbox account?

This will help me to assist further!

I have the app installed on my cell phone and it automatically transfers to my PC.

Do you take pictures using the built-in camera on your phone? Do you add any filters to your images during the picture taking?
