No. To further confirm, I’ve just made two phone calls using the loudspeaker, and I enabled it during the ringing phase as described. No echo on either side (I explicitly asked about that), very good call quality. I can’t recall anyone ever complaining about echo since I flashed Android 13. Additionally, the display also works as it should, i.e. no banding or that awful yellowish tint.

Can you share how you relocked the bootloader? The adb commands I’m trying aren’t working for me

Look at this link:
Ah OK, yeah that’s what I tried. But that gives “Command not supported in default implementation”. Seems they’ve removed the ability to re-lock bootloaders.
