boot-menu v2.0 - Galaxy A14 - Since I got better at C, why not to improve it?

A hacky boot menu with volume key and power control. Written in C.

Changelog
- Refactored most code with a new faster functionality
- Now relies on sys.boot_completed instead of timeouts
- PID based memory system
- Memory aware, and cares about CPU
- No more sleep and kill, just SIGTERM once not needed
- Separate thread to check for boot state
- Vibrates on both ready and done
- No timeout, menu is functional until system boots
- If picked option 1, bootanimation plays as expected just like it should normally

Can not modify this file and must bind it instead

Dead SystemUI fix in FOD based ports - Galaxy A14

SystemUI dies because of ${fps_position} being incorrect or not found, which is FOD related. And since it is universal among all system images and only occurs on Galaxy A14, it is not system related.

String ${fps_position} is found in /sys/devices/virtual/fingerprint/fingerprint/position which is incorrect by default and should be an integer or a list of floats, so the easiest fix is to put a number there.

Since that file is not modifyable, we must create a dummy file somewhere with an integer inside and bind it to our file, or can we just bind an existing system file which has a number? I picked /sys/power/pm_async to bind there.

But we don't have to do that each time on boot using adb, why don't we just put it in some rc file with sys.boot_completed property?

We need to pick a small rc file which has that property without any additional conditions to ensure command is executed, in that case logd.rc is perfect. Final command below.

echo '    exec /system/bin/mount -o bind /sys/power/pm_async /sys/devices/virtual/fingerprint/fingerprint/position' >> /system/etc/init/logd.rc

I wrote an extremely accurate battery monitor
This is the power of Python and math ⚡

Batt - Galaxy A14

Accurate up to infinite visible decimal points and 7 real decimal points approx

Just pure Python and math, no imports. Preview here

Listen I'm bored ok?

BetterBattery - v1.0 BETA - Preview
Accurately observes battery percentage in real time

The app is still experimental, it tries its best to run on all android phones. It worked on my A14

Relies on current_now, charge_counter, level, capacity and other props in addition to pure Android Java and Math. Similar to batt.py in terms of functionality but not hardcoded for one device.
