You are not alone
This is happening to many people.
Only one solution. Go to service center, give them 8000 rupees, and they will change motherboard of your phone.
No other solution
Sorry

Mother broad change is only solution.

Just download the A51 firmware from sammobile and then manually update with PC

It is only software issue not hardware
