I am often uploading photos I take to my website. On my Nexus 5 I can press the <input type="file"> button and can chose "Camera" take a photo and I get the temp file name in the input tag showing up. When I upload the server gets this photo.
On my Nexus 6, when I press on the button, I also can chose "Camera" and take a photo but it never updates the input tag with the temp file name and the server doesn't get any file either. I'm not sure if it is something on my phone or what, I already reinstalled Firefox but it didn't fix that problem.
