So, as I have posted in a post before ( https://r2.community.samsung.com/t5/Galaxy-A/Samsung-galaxy-A71-software-update/td-p/6877862 ) that a samsung executive had said me that Samsung A71 would get andorid 11 withing 1 or 2 months, now that comes true, I guess.
Android 11 Test firmware is already here.
Just wait some more days.
May be it will first come with beta tests and as of the firmware code it will come with January security patch. So, if we get the exact same update then we will get it by february (if stable update comes) or we will get it within mid february (if beta update comes). But if the same firmware dosen't get released then anything else may happen.
