[Resolved]  Samsung — Samsung M series auto restart issue

I've been a Samsung user since a couple years on 2020 I switched to Samsung M21 when it was launched.
Since the last few weeks I've been been a serious issue like freeze and then auto restart. I've haven't even accidentally dropped my phone and when I visited the service center for god's sake they told to pay 8k to fix this damn problem which was caused by you guys after the recent update !
I clearly said no to them and went for searching a solution. Seems like there are thousands of complaints and your damn company haven't approached accepting it's their fault they'll fix it.
When the note series blasted you repaid the world no-one trusted you guys . Everyone was scared about buying a phone. And even now the damn Exynos 9611 processor smartphones are facing the same issue and you're still mum.
This is just insane!
My device already restarted twice while writing this and now I'm on my computer.
