Too weird, worked indeed for me as well!🤔 Massive thanks, otherwise i'd be f.... I have tinkered with my case to invisibly add car mount magnets, so gariantee would be a no go 😏
Putting in some more info below since it might help others finding this easier 😇
S21 Ultra clear view cover issues, does not work , stopped working after December android 12 software update.
Had this before after EACH software update on S21 (never had issue on s6, s8 or s10 w/clear view cover though). But up till now a removal/reattaching of the cover and sometimes a restart helped getting it to work again.
Not this time though. Tried all else: wiping cache partition, turn off/on NFC and other suggestions i found to no avail.
Then after some deeper searching found this thread and whatdoyouknow:
Removing cover, connecting to USB (pc in my situation), putting cover back on, removing USB and it works again 😳
Many Thanks Gonzovisionairy!!!
I found the reason why my s20fe stopped responding to the clear view cover. I put on a little steel plate on the back of the phone as a part of the magnetic car mount. my phone stopped seeing the cover, the accesories option disapeard in settings. the steel plate coused this. the phone has 2 hall sensors, one responsible for noticing that the cover is on the phone and the other that recognizes the the cover is either closed or opened. the clear view cover has 2 magnets, one in front part of the cover and one in the back. If you cover the back magnet with something that lowers the power of the back magnet the phone will not see the cover.
in my case I just placed the steel plate of the car mount just 0,5cm below the magnet of the back of the cover.
my problem got solved.
if your phone does not see the cover maybe there is something wrong with the back magnet of the cover and the hall sensor does not see it.
You can alcatel the magnets with a coin.
