Eureka Manager v1.1 — Display + FlashLight, AMOLED black, GPU voltage & °C fixes

Eureka Manager v1.1

Display + FlashLight controls, AMOLED black theme, GPU voltage & temperature fixes.

What's new

Ported from EKManager (feature merge)

• Display Control — Samsung mdnie interface: screen mode presets, white balance (cool↔warm), night mode / blue-light filter with intensity, color inversion (accessibility), color lens with color+opacity. Hardware-based via /sys/class/lcd/panel/mdnie/*.
• FlashLight Control — torch brightness level 1–10 for the rear camera flash, with the a10-series raw-level quirk handled automatically.

Fixes

• AMOLED solid black default theme — first launch now defaults to true #000000 backgrounds across the drawer, fragments and dialogs (was gray). Switch to light/auto in Settings.
• Temperature rendering (°C) — the "Checking info" / overall screen showed a corrupted ºC glyph (double-encoded UTF-8 in strings). Now renders °C correctly, everywhere (°F, µV, ellipses fixed too).
• GPU voltage controls — current voltage showed 0 mV. Fixed both sides:
  • Kernel v1.3: gpu_get_cur_voltage() now returns the real ASV voltage for the current GPU clock
  • App: µV→mV conversion for display; writes round-trip via the standard Control.write mechanism

Device support

Full Exynos7885 family auto-accepted when the Eureka kernel sysfs surface is present (asv_margin / baseband_guard classes) — A10/A20/A20e/A30/A30s/A40/M20/M30s, plus the explicit model list.

Requires

• Eureka Kernel v1.3 for GPU voltage display (real mV); other fixes work on v1.2+
• Root (KernelSU/Magisk)

All prior features kept

ASV Voltage Margin, Baseband Guard dashboard, CPU/GPU controls, DVFS, thermal, I/O scheduler, entropy, VM, build.prop editor, apply-on-boot.
