1
Understand the display before changing it
- Density, DPI, PPI, resolution, dp, and sp explained without gaming myths.
- Font size vs Display size vs custom density, with accessibility settings first.
- What wm size and wm density actually override, including the reset forms.
2
Choose and prepare an access route
- Change logical density without root using the least powerful suitable method.
- Set up Shizuku through Android wireless debugging and understand what survives a reboot.
- Keep a recovery path before testing any advanced display value.
3
Test Android ad-blocking layers
- Compare Private DNS, local-VPN, browser, app-specific, and router filtering.
- Use repeatable tests that distinguish a deliberate block from network failure.
- Treat detector results as evidence for one test—not proof of complete coverage.
