A Few Months Old Xiaomi Redmi Note 11 Developed an AMOLED Burn-in

currently facing a significant challenge concerning my Xiaomi Redmi Note 11. It is only a few months old, and the screen has already developed an AMOLED burn-in. The reader for fingerprints....It is attempting to work extremely hard, functioning barely with a pristine phone. Additionally, this device is prone to spontaneous shutdowns and episodes of overheating. I will not tolerate these problems any longer; therefore, I am requesting a return. Should that not occur, I am prepared to assert my consumer rights.  Please recount your anecdotes if you've also had these problems, these guys need to hear them.
