I also been waiting a ultra size phone to replace my huawei mate 20 x. So far I have listed mi 11 ultra, S21 ultra and Xperia 1 iii. I am not really a Samsung fan coz I used to own a Samsung note series and the overall phone performance will lagged after 1 year. Unlike my old mi max and the current huawei still going strong. Sony Xperia 1 iii has everything I like, no pinpole front cam, a 3.5 headphone jack, side fingerprint scan and yes, it allowed mircosd expansion . Just that battery size is smallest among the 3. But for price wise. S21u is the cheapest among the 3..less than $1300 for a 256gb model.
