I am facing the same issue on my Samsung Galaxy F23 5G.
After the November 1, 2025 security patch update, my phone started restarting automatically, and Wi-Fi and hotspot are not working.

Thanks for replying
The first cause auto restart is turned off I have resetted the phone four times but it didn't worked I use official Samsung charger,There are not any updates available.
With going one step further I also use Odin to put again the software
Still it didn't work. And the last update did binary value change so I can't even try using older firmware to test out,the phone was already out of warranty
I have started to feel it's a software issue because it does not happen constantly but when it happens the phone's cpu temp rises up and then settles down itself after a few reboots
