why can't power down since update?

To power down you need to hold the volume and power off button at the same time and it will display a sos call and a power off button respond quickly after pressed to avoid connecting to SOS not in an emergency.

I'm sorry to hear about the challenges you're facing with your phone, especially at such a critical time for work. It seems like the recent update might have caused a lock-up issue, preventing you from accessing your phone and potentially impacting your ability to use security tokens for your on-call responsibilities during Black Friday. If the power button isn't responding, you could try a force restart by quickly pressing and releasing the Volume Up and Volume Down buttons (on iPhones) or a hard reset by holding down the Power and Volume Down buttons simultaneously (on some Android devices). Connecting your phone to a computer might also trigger a response, and checking for safe mode can help identify if a third-party app is causing the problem. If all else fails, letting the battery drain completely and then recharging it might force a restart. If these solutions don't work, reaching out to your phone's customer support or your company's IT support for tailored assistance is advisable. I hope you can resolve the issue swiftly and smoothly to avoid any disruptions during your on-call responsibilities.

Volume quick presses and hold worked on the third try.

Thanks for the responses!

Sounds like it solved your problem - appreciate the corroboration

Charged last night, saw the nighttime charging screen with red clock for the first time, so assume an update went through. 

Now phone is locked up, white screen when going unlocked, and the power off button hold is not working. I do feel a haptic bump when I hold the lock button. Nothing happens, though.

I'm moving to primary on call for a fortune 20 retail company tomorrow for Black Friday, so this is an inopportune time for an update issue, as I have security tokens I need on the phone.

Going to have to jump through a LOT of hoops to get work moved to a different phone by tomorrow.

Only thing I think I can do is let it die, and reset that way.
