Maybe just rebond the oled contacts that were disconnected by heat

Idk

My s22u was super hot last update

I put a fan on it while updating

Maybe they need to throttle the update from over heating

Yeah but I think the damage can still be done even if the screen is off that's the thing

Hmm?

I'm just saying it's really hot when it updates

Just trying to reason why the light saber happens around updates

And potentially prevent it

What are you on about?

Nah most updates I've been through, the phone only displayed minimal text. Samsung font etc. Otherwise mostly black. Some videos show how to repair the oled, and seems to be contact issue. Plus dead pixel is just one pixel. The whole row is connected in a line circuit.

The oled is connected at the end through a laminated strip.

The heat probably caused delamination of some of the contacts, shorted etc that's the theory. They have to bond the oled piece. Same like the Samsung folds when people initially tore them off. There's occasion of the entire line going pink or green as the person tore it off

Anyway can't understand the video if it's the Chinese one.

But the whole screen green hue issue might reflect your power issue like you said. Which could be resolved or induced by firmware update.

Edit:
And another key point to support the delamination theory, it also happens to people using alcohol wipes and also tempered glass with glue

The solvent also increases risk of delamination. In fact whole screen can die, or less worse, light saber

If other companies that use Samsung oled don't have issue, it must boil down to the oled lamination production system that Samsung uses

Edit 2:
And why it happens during update but not when during use?

My theory is, when the phone up and running in the os environment, there is temperature throttling mechanism that may not be present while updating
