The volume slider never moves, or moves and snaps back, on Xiaomi and Oppo phones. Separate DND refusals from sound-assistant overrides and test media and ringtone streams individually.
No universal split-screen API exists, so the honest routes are three: OEM app pairs, guided UI sequences, and sequential launches. Which to use on which brand.
Battery, DNS mode, active profile — visible at a glance on floating buttons, updated by events instead of polling, and dual-purpose as controls. A dashboard that earns its pixels.
In Japan and Korea the shutter sound is a legal safeguard, not a setting. Where muting is lawful, how the sound is wired, and a MacroDroid build that restores volume on exit.
Logs are not your storage problem — app cache is. What log buffers really are, the one safe reclaim command, and a weekly maintenance macro that frees real space.
Strict encrypted DNS on café Wi-Fi, relaxed at home: the two private_dns keys, a two-macro design keyed to network trust, and the captive-portal procedure.
Seasonal apps should not hold year-round permissions. Android’s auto-revoke, AppOps’ quiet ignore mode, and a monthly audit macro — with a strict do-not-touch list.
Ninety seconds for messaging, ten minutes for recipes, restored the moment you leave: per-app screen timeouts built on one settings key and a captured baseline.
A boot macro that verifies your tweaks, quietly repairs the ones updates cleared, and writes a log you can actually read — designed with delays and fail-safes, not hope.
Android guards the radio mode harder than almost any setting. The ladder from testing-menu choices to assisted macros — and when forcing a band is the wrong fix entirely.
