Tested on physical iOS device and Android simulator and works as expected. One notable thing I tested was setting the `creationTime` of a photo to the future and making sure that it wasn't pushed to the front of the photos displayed on `MediaGalleryKeyboard`. This was the main bug with using `creationTime`.
Photo set to the future:
{F139223}
What Camera Roll looks like (photo from the future is still behind last photo, which is from today):
{F139224}
What `MediaGalleryKeyboard` displays (photo from the future still stays behind last photo in Camera Roll, mirroring the ordering of photos in Camera Roll):
{F139225}
