Battery draining issue in Mokee ROM

Hi, I'm using your Mokee ROM, nice ROM, already donated 68 CNY, hope you already get the money. And I noticed that my battery is draining very fast when phone is idle. For example, last night, the battery drop 20 percent when I was sleeping. And I don't think this issue was caused by third party apps, because I'm using the same apps as I was using MIUI. Please fix this bug, thank you.

Fingerprint scanner icon shifts position when display is waken

Demo

USB Debugging disabled after each reboot

ADB over USB works fine once enabled through the Developer Options menu but, after a power cycle, the option is disabled automatically.

MIUI 3-button navigation bar icons are not overridden from Pixel Experience ones

.

Please update the mokee rom

Hello, sir, I'm using your mokee rom, have you forget to update the mokee rom?? There are zero update for mokee rom more than a month. The fingerprint and NFC stop working again , and phone randomly dead all the time. But I saw you fixed these bugs on your other roms. So will you update the mokee rom? Please~~

Cannot find entry [email protected]

When device going to doze, following error appears:

01-30 19:17:13.428: I/hwservicemanager(570): getTransport: Cannot find entry [email protected]::ICitSensorService/default in either framework or device
01-30 19:17:13.429: I/QTI PowerHAL(758): Got set_interactive hint on= 0, count= 86

01-30 19:17:13.429: E/libsensor-C2SNotifier(752): Sensor: sCitSensorService get failed!

It probable causes display is not dimmed on Ambient display. On original firmware this driver (and display dimming on Ambient display) is working correctly:

01-30 20:37:20.802: I/libsensor-C2SNotifier(797): Sensor: notify type: 1, value: 3`

Maybe something is missing in manifest.xml

Display dims when finger is placed on fingerprint scanner

Description:
When a finger is placed on the fingerprint scanner, e.g. the fingerprint scanner is activated due to finger/fingerprint detection, the display dims, e.g. lowers brightness. Removing the finger, or successfully unlocking the phone, restores normal brightness. The display is dimmed as long as the finger is on the sensor, until it's eventually recognized.
The brightness change doesn't happen at the Android level since the brightness slider doesn't change during this weird behavior.

Extra details:
In the original MIUI, we can't see this behavior.
Was also present in the past Pixel Experience updates.

Version:

• base: latest global NON EEA V10.2.13.0.PFAMIXM fastboot ROM (clean flashed)
• firmware+vendor: xiaomi.eu 9.8.1
• Pixel Experience: 28 august 2019
