I'm considering switching from a Samsung to an iPhone. My biggest criteria is the quality of the camera and photos. I recently discovered that when you view photos that you've taken with iPhone 8+ and the iPhone X the photos don't "fill the screen" in Playback mode. Also, iPhones don't have the ability to take a photo using voice recognition (with the rear camera). My question is - are there any apps that will allow you to change the default picture ratio so the photos fill the entire screen during playback on the iPhone 8+ and the X? And any that will enable you to take a photo with voice commands? Thank you!
