This app screwed up my camera on one of my phones. I did everything possible and ONLY WHEN INSTALLING THIS APP DOES THE CAMERA ON MY PHONE WORK AGAIN. It's happening on my other phone now which never had any problems with its camera until I installed this app. Serious issue!!! Super easy to use. I just buy whatever I need from anywhere and as long as I have the receipt that I take a picture of, it works. Serious issue!!! This app has a bug that screwed up my camera on both of my phones.
