I've been facing similar issues intermittently since the end of Aug, 2020. Now compounded with unusual battery drainage. With the current Covid pandemic, it is next to impossible to get to the nearest service center which is in Guwahati/Kolkata, as there are zero in our state. And then there's the uncertainty of solution even after going through the trouble of travelling to these places.
I took a leap of faith and deviate from my usual practice of going for products of well-established companies. Now I'm doubtful of my decision after facing all these issues within the 1st year itself.
