Hello. Samsung phones have always been reliable when it comes to budget Android smartphones. With that credence, I had purchased Samsung M30s on the 29th of September, 2019 from Amazon. Recently, after the Android 11 and OneUI 3.1 software update, there have been a lot of issues with the phone.
First thing, just seconds or a couple of minutes after connecting to WiFi / Data, the phone switches off automatically. If you don't turn on the WiFi and data, the phone starts rebooting just when you open an application. While rebooting, the phone gets stuck at the Samsung Logo, and never starts. Many tutorials online suggested a factory reset.
But, android's recovery mode itself failed to start, even after holding the volume up button and the power button as directed by Samsung's technician.
The technicians at the service center told us that the issue is with the motherboard, and will cost 7-9K inr since the warranty has expired. To my surprise, I came across the issue just after a couple of weeks/ months after the warranty expired.
Having purchased the phone of a reputed brand, like Samsung, for Rs. 14029, I expected the phone to function reliably for at least a couple of years. However, to my disappointment, I am forced to shelve out money to get this repaired or buy a new device. I would like Samsung to refund.

I have attached 2 pictures of the smartphone with its box, and the amazon order invoice.
