[Redmi K20 / Xiaomi Mi 9T ROMs, Kernels, Recoveries] Sony98:
Spotted Bugs:

-Settings/display/rotation doesnt work (Let crash settings app)

-Settings/display/Device design doesnt work (I can choose what i want, nothing changes)

-Settings/Horns/System/Music ticker resets every time after choosing it to on

-Settings/horns/buttons.....There is nothing. A blank screen.

-Settings/Display/Night Light function is buggy, nightlight doesnt work on low brightness. It automatically turns up the screen brightness which makes this feature useless

-Settings/horns/gestures/screen off torch doesnt work so good. There is another option in normal settings to open camera if you double tab your power button.

Double tab for torch doesnt work. Long press power button works, but i can the light turn on and off only, if the screen is enabled between this conditions.

-Settings/horns/statusbar/statusbar icon/Mobile data: Let appear strange icons on status bar, which i dont understand and the STAGos Logo.

-Setting/horns/Lockscreen/lockscreen shortcuts/Link unlocks.....This Option doesnt work. i still have to put in my password to use camera.

If iam on Lockscreen, swipe from the right or left buttom corner to open camera or Phone, I have to put in my unlock pattern first without fingerprint option,then If i swipe from Left to go Back(Full screen gestures), because i dont want to type in the long pattern, the screen get white and the fingerprintbutton appears. If i then put on my finger to unlock, it unlocks the device, but the screen is a little bit darker and TOUCH doesnt work, just the fullscreen gestures are working.

-If i activate full screen gestures and deactivate the Home and backbuttons on bottom screen, the apps on homescreen doesnt move automatically downside as well as i cant move them more downwards. There is now a big gap with nothing.

-There is a option in settings, that makes possible to unlock the smartphone only with fingerprint after a restart, nothing else.

But that dont work so well. If i unlock the phone with FP, it only shows a Loop: Smartphone get started.

So i have to solve the pattern lock, then everything loads correctly.

-No matter which music player i use, if i want to play a song the sound doesnt come out of the loudspeaker. It plays, but there is no noise coming out. The only way to fix this is putting the volume up and down a bit. Bluetooth works.

-Fingerprint is buggy sometimes. It recognize 2 times short the finger in 0,5 seconds and doesnt accept it, no matter how often i try it. Then it locks because to much tries.

-No ideo if this is a bug, but does the BT device control the settings in Developer options/bluetooth ? The options are not changable or they will not be accepted, no matter if a bluetooth device connected or not.

Maybe its buggy ?

-System Equalizer has no function. It doesnt work. Equalizers from third party music apps also doesnt work because that.

What i also spotted:

-Uninstall system apps is not possible ???? I use magisk, but no app can uninstall system apps lol

-For the camera is an updated version outside

-Installing Ultracam (https://xdaforums.com/android/apps-games/gcam-mod-ultracam-v1-1-8-t4027633) not possible, always crashes when trying to start

Feature wish:

-changable vibration intensity and vibration types, for example: 2 times short vibration for a message

-changable design in taskmanager

-a better, maybe changable lockscreen (for example the option to change clock color and position)

-fingerprint could be a litte bit faster and bugfree
