Samsung — Samsung Galaxy M21 Motherboard issue

Address:

Plot No.21, Hitech nagar colony, Yellareddyguda -Kapra

The said mobile was purchased in 2019 and since then it is working fine. one fine day it suddenly not switching on then taken to Samsung service center and they have said that Mother board issue and mother board need to be replaced. I heard this similar complaint from the forums and heard that this was happened due to recent patch update from Samsung caused this. without having any issue how come the mother board issue will come in to the device.
I am very good fan of Samsung mobile, now i am loosing belief on the products of Samsung as i have many complaints on the mother board failures in recent months post warranty periods of those mobiles.
Samsung company have to look into the provide the rebated price for the mother failures as this the failure of the product.
