I've tried to reset network settings, wiped cache partition, and even factory reset didn't solve the problem!

the device was working fine before this update,

how can I roll back or uninstall this update?

Or if you have another way or have a patch to solve the problem, please advice

Can you try Safe Mode just as a process of elimination please.

> Safe Mode  > turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 

Once the software is accepted you can't natively roll back to the previous software via the phone's settings @AhmedEmara 

The only way is via options shown on

Disclaimer 》

Using a Custom Rom / trying to use other methods to rollback firmware can bring about an unstable phone or it may not work properly if the process glitches or the wrong Rom is used. It may stop Samsung Pay from working if the procedure trips your Knox Counter.A person takes full responsibility if they perform this process and do so at their own informed decision. Again the process may trip Knox and may affect the Samsung Warranty. Samsung could levy a charge to put this right or deny support.

Alternatively you could ask a Samsung Service Centre for assistance and or send feedback via your Samsung Members App under the GetHelp section to ask for assistance.

I wish you all the best. Take care.  😎

Thank you for replying, but Safe mode didn't solve the problem.

I visited a local Samsung Service Center, they are insisting it's a hardware problem and asked me to pay for their error. So I refused and mailed Samsung about this bad experience after 18 months of a smooth-running device.
how on earth do they send updates to wreck their customers' devices like this?!
Seriously I'm waiting for their reply, before taking further steps.
