Since you have already Factory Reset, submitted an error report to Samsung (good luck with getting a speedy response lol), I'd start with Wiping Cache AGAIN from Recovery & then Boot into Safe Mode and run the device in Safe Mode for at least the approximate amount of time where a Freeze Reboot would occur.
It's not a known issue with your device, so I'm thinking that it's likely to be a 3rd party app causing the issue.
You could also try Uninstalling ALL 3rd party apps, & then add them back, one by one to figure out what app is causing the issue.
One other thing that you could try, Factory Reset, but DO NOT RESTORE ANYTHING! It's possible that you are restoring the issue.
So if it still occurs after a Factory Reset & a CLEAN set up, then it's possible that it COULD be a hardware issue, but that is hopefully unlikely.
My guess is that it's a conflict with an old app or a setting somewhere.
Hi, as suggested by RedDogRabbit you can try wipe cache partition and also perform safe mode.
Below are the steps to perform clear cache partition.
1.Turn off the unit.
2.Press and hold the volume up button and press and hold the on/off button. When the Android logo is displayed, release all keys ("Installing system update" is displayed before displaying the Android system recovery menu options).
3.Press the volume down key repeatedly to highlight "wipe cache partition".
4.Press the Power key to select. Press the Volume Down button to highlight "Yes" and press the Power button to select. When the wiping of the cache partition is completed, "Reboot System Now" is highlighted.
5.Press the Power button to reboot the unit.
Please reboot your device in safe mode and check if you are experiencing the issue. If you are not experiencing any issues in safe mode, then the issue could be due to any third party application you installed recently. To do this, you need to completely power off the phone. Then, power on the phone, and when the Samsung logo appears, press and hold down the Volume Down key. If done correctly, "Safe Mode" will display on the bottom left corner of the screen.
Even after performing the above steps, if the issue still persists kindly get the device examined by the service technician.

"Are you suggesting that I now own a phone that must be run in safe mode only unable to use any apps",
Hardly, I haven't personally experienced any issues with any of my apps. I am only offering possible explanations & solutions for your device's issues.
"it is up to me to figure out what app that is from the play store or samsung app store that does not work well with this Samsung device"
It's not up to others here to figure out what apps, if any are causing your issue. However we will certainly try to help, but we are not paid Samsung employees.
"The multiple requests for help that go ignored. Is this the Samsung way now"
Samsung's Customer service is not the reason to buy their products.
"At this point I am thinking I have put my faith and money into a company that does not care"
I don't know if it's because they don't care, or if they just don't have the knowledge or resources to actually do much more than cut 'n paste answers, often without actually even understanding the question. Samsung is not unique in this regard.
I am quite confident that some of Members here are substantially more knowledgeable than most of Samsung Canada's Support people.
"Even this forum,while helpful and useful seems to be another way Samsung washes its hands on customers and says "You guys help each other, we don't care enough to respond"
It certainly seems to be the case.
If you try my suggestions, then at least you should be able to determine if it is a hardware issue, or if it's a conflict with apps or settings.
I wasn't suggesting that you never restore all your apps & settings, just don't restore anything after the Factory Reset, to narrow down what the issue may be.
I know what steps I would be taking if it was my device. I'm not giving any suggestions that I wouldn't follow myself.
You could always just take your device to a Samsung Service center, and hope that the tech is knowledgeable enough to figure out what is going on.
But, who knows, maybe tomorrow you'll get a reply from Samsung support, saying that they have reviewed your error reports, and they know exactly what the problem is?
Wiping Cache might help, but since they already did a Factory Reset, I'm pretty doubtful that it will do much.
It really can only be one of a couple of things, a conflict with apps / settings, or hopefully less likely, a hardware issue.
