I know this might be an unpopular opinion but it's extremely hard for me to use Face ID on an iPhone because I have trouble keeping the phone positioned correctly. I really, really hope Apple is able to come up with a way to do Touch ID on iPhones once the iPhone SE third generation is no longer an option. I believe I checked all the accessibility options and it's still very hard for me to use. I'm definitely open to suggestions or thoughts on this. This is the only reason I've stuck with the iPhone SE because I've tried this numerous times and have never been able to keep it positioned correctly long enough to complete the setup process, other than it happening once out of pure luck.
