I'm guessing the large Australian supplier that you received a response from was Kogan.
Don't hold your breath waiting for a patch from Samsung as it has already been six days!
I'm afraid that the only temporary solution that I am aware of it to install the previous firmware for your phone as documented elsewhere in this conversation, and it really is temporary because the auto updater almost immediately starts requesting an update back to the faulty firmware.
Samsung really need to at least turn off the forced update to the faulty firmware!!!
Same story here, US purchased unlocked Galaxy S9+ (SM-G965UZPAXAA) worked fine with New Zealand Vodaphone until this update last night. Same symptoms reported here, constant popups, very slow and glitchy behavior, extreme battery use, etc.
I have spent the evening trying to figure out how to revert the firmware version using Odin per others' advice here, but am having trouble finding and downloading the correct version. I guess I'll waste another evening tomorrow trying again. Very disappointed with Samsung for letting this get through in the first place, but why in the world can't they make it easy to revert version to last known good config?!
I too have the same problem.
I'm in Australia with Galaxy S9 64 GB unlocked phone keep getting this IMS stopped working notification.
I too have experienced that my phone is very slow fter the update and the touch screen is unresponsive. I've also noticed that the battery drains verqy quickly now. Previosly I could go 2 sometimes3 days ona full 100% charge. since the update this monring it was at 100% fully charged and by 11am it was at 30%, and I wasn't even using my phone.
Samsung, this is shameful. The update has rendered our phones useless.
when will an patch fix be delivered. This is extremely frustrating.
Yet another victim! I also performed the recommended update on Sept 7 and now have the same fault. In addition the phone freezes/hangs for several seconds when touched and burns through the entire battery power in a few hours, running very hot! My phone was purchased in Australia from a Samsung reseller 5 months ago and worked faultlessly until the update. I too have spent several hours researching the internet/Youtube etc. performed multiple factory resets and tried all the recommended fixes described in this thread (plus many others) without success. Even, went to the Samsung store for assistance and was told that my S9+ was an international model and as such was not supported by Samsung Australia. C'mon Samsung do the right thing by your loyal customers and please fix the problem. If not, it might be APPLE time!
