Following the update of UI 7 in late May 2025, my phone will no longer detect any wifi networks, nor allow any bluetooth pairings. I have (1) reset network and bluetooth settings, (2) cleared the cache partition, (3) factory reset phone, (4) re flashed the stock rom.

Still doesnt work. So, good luck with the medical monitoring apps that I need (including diabetic Blood sugar alerting). 

Zfold 4 Update -> Trashed phone + Risk of death

Thank you Samsung.
