To start off with I will say that Snapbridge works great for me.
If you plan on going out shooting and have any intentions of using Snapbridge to transfer images to your phone be sure and take an empty card and NOT one with a lot of images already on it. Your camera will load everything that is on your card in the camera to your phone so make it easy on yourself when using Snapbridge and hasve as few images on your card as you can, this will greatly lessen the number of images that you will have to load on your phone to pick from so you can send it to a friend or post them on the web. Your camera will send everything on the card both new and old to your phone so you can pick which ones to keep and if you have taken a few just recently while you are out and they are on the card by themselves they will load the thumbnails on your phone much faster and there will be fewer to choose from so you can select the ones you want to download to your phone quicker. As far as I know everything on the card will load to your phone in thumbnails for so you can choose which ones you want to keep and what size file you want them to be.
