Software update 6 is downloading on my Verizon Fold 4. It's a large download, so I am assuming it's One UI 5.1
 
I have F936USQU1CWAC, February security patch, One UI 5.1
Right... I was quoting the unlocked, F936U1, in my previous post. Seems like you do indeed have the One UI 5.1 on your carrier locked, F936U, device. I hate all this locked and unlocked phones for the U.S.. :D

At last!

All Canadian devices, F936W, have now received the One UI 5.1 and February security patch update.

This is a big jump for Canadian owners who were previously on the 01 December 2022 security patch.
 
Looks like the new update could be causing battery consumption issues.

As per post #16... I have now been on this One UI 5.1 update for 10 days and have not experienced any battery drain or lags. In fact I would go so far as to say that my battery life is improved.

2 caveats are that I do not use the Samsung keyboard which some people have linked to a battery drain and the other is that as per all updates I used...

Wipe Cache Partition, Repair apps & Galaxy App Booster

Downloaded VZ unlocked this AM.
On the first day, haven't noticed anything unusual, though I ritually: restart, clear system cache, clear often used apps cache, and luckily no problems reported.
Will circle back if anything changes...
Lots of camera tricks this time!
Peace
