I have been using Galaxy M30S (128 GB Variant) for 1 Year & 3 months. It was working fine for my needs.
Suddenly, 2 weeks back while removing from charging the phone was really hot and was stuck. I restarted it immediately.
But since that day It started restarting all of sudden in between. even during calls, it was restarting automatically.
When I have visited the store center, the store center people said that it's a motherboard problem & I need to replace it. The cost will be 7200/-
which is close to half of the original price.
But the issue is not faced by me alone. latest amazon reviews say the same.

Complaint about M30s Motherboard issue.
I have been a really huge Samsung fan till date. But this was really not expected from an esteemed brand like Samsung.
