My biggest issue is with Face-ID. Its been really bad. I find myself putting in the code so much more than I’m used to, and it’s awkward making sure it’s always the right distance and angle from my face. Touch ID is a 100000 times better IMHO.
But then there is also the many extra steps; Unlocking the phone takes longer time, wait for face-id (wich often doesn’t work) THEN swipe up. Oops didn’t read my face. Press power button, press it again or tap the screen to try again, there finally, NOW you can swipe up. And your on your homescreen "sigh"!
And then there is the silly excuse for a stutus bar, which has been moved up into the "ears" of the display, where hardly any info fits the little space. So now you get the pleasure of pulling down the control center window everytime you want to check if your vpn, battery% or bt is still on. No need for that step on my old 7 Plus, it was all RIGHT there visible up top.
There is the extra time consuming (compared to the previous iPhones) tap and step to close apps completely in the background too (of course).
You can learn to deal with this (face-id being the worst), or go back to your old iPhone like I did. It was a sweet relief picking up my "old" 7 Plus after using the X, it really just works. Just like the times I would try android for a while and come back to iPhone with a promise to never leave again, except this time I did not come back from an android, but from the supposed future of iPhone. Which is really sad to be honest.
