- Side button held + top button saves the screen, popups and toasts included,
to /sdcard/screenshots/scr_NNNN.bmp (24-bit BMP). The flush callbacks copy
one forced full re-render into a PSRAM buffer. A white flash and a toast
confirm it. The side button's mute now fires on release, so holding it a
little long before the top button doesn't also mute. In the sim, the page's
Screenshot button downloads the file.
- The lock screen goes dark after 30 s even with auto-off at Never (a boot
PIN, a pocket wake-up, a message), and sooner if auto-off is shorter.
