Is that the standard answer when Samsung actually has no clue as to the cause? As it didn't happen until the latest update, that would make it Samsung's fault, so if the phone is taken to an authorized repair facility, will Samsung cover any cost incurred if the phone in question is out of warranty?

If you have any battery patterns before and after the update, then put it in the Samsung error report.

My samsung a14 5g just screen froze for bout an hour and it refused to restart with volume down and power button nothing worked except for plugging it into charger even tho it didn't need a charge . I wiped the cache in recovery mode and still having issues with screen not being able to work with touch . All this happened after update . But it's ok. I wanted badly to upgrade from android 14 to 15. Of course battery is gonna drain quick it's an entire software change to go from one android level to the next.

I seriously think Samsung is breaking phones with updates to force customers to buy a new phone.  My A14 worked great until Samsung started updating One-UI and Device Care.  I am convinced Device Care is malware.  After last update, it consumes 9% of my battery, I cannot uninstall it or disable it and it is always transmitting over WiFi or Mobile data.  The two biggest drains on the battery are One-UI and Device Care.  After last update, my A14 is totally useless, especially when I am using Android Auto or Maps for directions.  If I am running maps or android auto, I cannot open any other applications and it takes 30 seconds to disable Bluetooth and shut android auto down.  If I restart my phone, it takes 1 to  2 minutes for the phone to restart.  The phone worked fine when I first bought it but with each update it has slowed down and now to the point that I have gone out and bought a cheap Boost Celeros phone that outperforms the Samsung in every catagory.

You've update a very reliable old A14 so many times it hardly runs 4hours off charger.

 
If I wanted all the "cool stuff" you shove onto it.. Id go get it.
 Leave me and my phone alone letting us opt out of your exams and data harvesting is just impossible. Having no life of your own.. you seem compelled to live vicariously through my old phone, without it, you have no raison d'etre.
