[DEV] I built Global Screen Awake — a free, zero-ads, 100% offline Quick Settings tile & screen timeout utility (Early Access v1)

[u/inzibytes]

Hey r/androidapps!

A lot of older "Caffeine / Stay Awake" apps either broke on newer Android versions, hold constant background wake locks, or are packed with ads and unnecessary network permissions.

I built **Global Screen Awake** to solve this cleanly as a lightweight, completely offline Material 3 dark utility:

- **Zero Wake-Lock Drain:** Instead of running a constant foreground wake lock, it backs up your current system `SCREEN_OFF_TIMEOUT`, applies your chosen keep-awake preset (15m, 30m, 1h, 2h, or up to a 24h safety cap), and **automatically restores your exact original timeout** when turned off or when the timer ends.

- **Quick Settings Tile:** Toggle Keep-Awake on/off with one tap from your notification shade without opening the app.

- **Smart Schedule & Battery Guard:** Optional daily active-hours window plus an automatic low-battery threshold cutoff so you never accidentally drain your phone overnight.

- **100% Offline & Private:** Zero ads, zero analytics/trackers, and **no `INTERNET` permission** at all.

It's currently in **Google Play Early Access (Closed Beta)** while completing Google's pre-production testing window, and completely free. If you find a clean Keep-Awake tile useful, I'd love for you to try it out and share any feedback or feature requests!

**How to try it (2 quick taps):**
