One Photo Failed to Import

Hi. 

I obtained some free presets from a couple different websites. Unless the files are corrupt, they will not import into my newly installed lightroom app on my iPhone.

I have followed instructions from multiple websites and they all virtually give the same instructions. I unzipped the file on my laptop and saved to my google drive. I can see the files in my google drive on my iPhone.

At first, when I opened my light room app and went to add a picture, I selected the “from file” option and navigated to Google Drive and located the unzipped file. It did not add or import.

I even downloaded the file to my iPhone itself and emailed myself the downloaded RAW format picture. I saved the picture form my email to my photos on the phone. It showed up there as a gray square. I understand it is normal for it not to open as it is not actually a photo.

In my light room app, I do the following.

1. Select the three dots on upper right
2. Add Photos
3. From Camera Roll (the file is saved to my camera roll on my iPhone)
4. Here, I select the file. It is black and it says DNG on it.

Then I get a message that says one photo failed to import.

I can’t afford the desktop version of lightroom and am so happy for the mobile app.

Am I doing something wrong?

For some technical information, I have an iPhone 6s and the version of Lightroom on my phone is v. 5.2.2 CD82C9.
