I have a 13 Pro Max coming Monday, and guess what, sitting on my desk in front of me is the case it will go into immediately after I take it out of the package. Kinda sad. Someone said they're not as slippery as the older phones, but have sharp edges. Okay on something the size of a 4S, not so okay on something the size of a small tablet.
I hope you can get a few more years out of your phone too!
Have the 12 Mini now which is the next smallest phone, but feel much less secure with it because I can't reach both the top and bottom of the screen at once with my thumb while holding it securely in one hand. Have to always be sliding up and down to reach what needs to be hit, which makes it much more likely to be dropped. Would kill for a proper small phone again.
