higher dpi/4k screens.
oled pixel layouts already have fewer subpixels than they should for say a claimed “1080p”, leading to weird blur or aliasing in places.
My high dpi phone has made my eink reader redundant; the sharpness simply makes it way more comfortable to read, for me enough to be on par with print.
And now I can only await how long my phone will remain usable, knowing no new phones with higher dpi (600ppi+) are being made.
That applies to play integrity, and a lot of getting that working is juggling various signatures and keys.
The suggestion above which I replied to was instead about software-managed keys, something handed to the app which it then stores, where the google drm is polled to get that sacred piece of data. Since this is present in the software, it can be plainly read by the user on rooted devices, which hardware-based keys cannot.
Play integrity is hardware based, but the eu app is software based, merely polling googles hardware based stuff somewhere in the process.
