Samsung — M21 Mother Board issue after OS update

Hi,
I purchased an M21 last year and I was satisfied with the product. Its warranty period just expired 2 months back. I have done an update. After the update, it reboots and froze on the boot screen. When consulting the service center they told its hardware damage. Need to change Motherboard.

Why I should pay 7-8k for new Motherboard.

Who is responsible if Hardware is damaged due to glitch in Samsung system update ???

I was using old Mi phone for 4 yr (and it is still working flawlessly just has bit old hardware config.) But because of Made in India & Anti-China sentiments, switched to Samsung, laterally regretting my decision.

I have checked lots of thread in the Samsung Community, its look like I m not alone with issue, there are thousands of customer cursing Samsung.

In there copy past reply they are writing: Please follow this path to register your concern in Samsung Members Application (Open Samsung Members Application Get help Send Feedback Ask questions).

Just want to ask these support people, does this app supported on Non Samsung phones, as my Samsung is busted because o[censored]r #[censored]SystemUpdate

Never thought Brand like Samsung can cheat People like this.
