There's no custom ROMs yet so I'm more-or-less just playing with the stock ROM to get things working.
It seems like I can't get the DPI to go beyond 530 without annoying the stock apps. Stock is 640 DPI. DPI scaling makes full use of the stupid high resolution of the screen. I couldn't stand out of the box two notifications and bam you're scrolling in the notification tab. Add a few icon notifications and the whole bar is taken up. Silly for such a high resolution phone.
Bunch of Xposed tweaks later and bam. It works like a charm (including play store). Go below 530 DPI and the stock apps crash (see photos). Anyways smarter than me to figure this one out?
Photos tell a lot. It's night and day difference and now an awesome phone.
STOCK BIG FONT (removed some of the bloat)
THIS IS HOW IT SHOULD LOOK STOCK (DPI in the 400s)
EDIT: GOT IT. 530DPI is the limit. Now if someone smarter than me can figure out how to get the apps to play nicely I'm down. Otherwise I'm pretty happy with it as is.
