just waiting for the biggest update of this year maybe within 1 week we will receive Android 11 with 1UI 3.0... it is always better before we update do format our phone so that the phone will be fresh and battery will improve immensely...
no only S series will be announced and we are not sure about Note 21 whether Samsung will continue this model or not that is the reason why they gave support for Spen on S series phone as well as Z Fold 3...
