Hyundai Elantra 2020 Android screen removed from Elantra 2021, it works perfectly with all applications. The reason for removal is that I fixed the original dealership screen. The screen has YouTube and the "Thmanyah" app. The screen is removed, working, and has no issues. It installs without any wire cutting, plug and play with all its connectors and everything is complete. The marks on the back are from adhesive.
