I did not object to the splash screen. As you can see in my post history I had the x30 Pro / Edge 30 Ultra, which has working OTAs with open bootloader (unless rooted) and can be relocked according to my guide.
So if I get it correctly, when you re-lock the bootloader, you will still get the nasty splash screen that the bootloader has been unlocked.
This will not be good if the user wants to eventually sell the phone as it is considered tampered.
