Don't buy any poco and mi models. Lot of motherboard and software issues. Too much crowd in mi service center. Most of them getting issue even in one month after purchase
Sorry to hear that but my mother also uses a Poco M2 Pro phone and it still runs very well. Before that she was on Redmi Note 5 Pro but eventually the UI became too chunky after updates so I went for Poco since they allow disabling ads
Price is higher for 9 se and it has LCD instead of amoled.
I think moto g71 is better,same price for 6gb and 128Gb(instead of 64 here),just ordered one for my friend today
