Anyone who is interested in supporting S20+ development, I uploaded the LOS20 device files onto Github
https://github.com/Ronnz98/android_device_samsung_y2s
https://github.com/Ronnz98?tab=repositories
I made an first testing build and it booted! However there are still a lot of bugs:
What doesnt work: camera/sim/change resolution (doest scale so a portion of the screen is black), flashlight,
Any help is welcome!
