I havent needed to stup kiosk mode (yet), but whats challenging about it? I always wondered why would people put up with Windows on these kiosks, instead of a simple Linux OS?
There are window managers / compositors, which fulfill kiosk mode, ex. Cage.
I dont understand, the pixel 6 is bigger than the 8, isnt it? On gsmarena it says so. For me, i like the size of the pixel 8, as it is a little bit smaller than my previous phone.
Recently got the pixel 8, and installed grapheneos on it (which is very easy to do), and been great so far.
