Samsung — Samsung m31 freezes and auto restarts

Address:

chennai, tamilnadu

I bought the samsung m31 on march 2020, past few weeks my mobile started behaving abnormally, freezes while using and auto restarts continuously. i visited customer care for the same, but they flashed my software and told me that, if the problem persists then motherboard has to be replaced newly. Since many other users of same model mobiles suffering same issue, how can it be a fault from user side? and i doubt it to be manufacturing defect from samsung side. I request to take necessary actions to rectify the same by either recalling the mobiles or bringing up free service for all affected mobiles.
