Samsung Galaxy A11/A21/A21s: How to make a factory data reset (hardreset) with the buttons?

With this video, I will show you, how you can format (hardreset, factory data reset) the Samsung Galaxy A11, Galaxy A21 and Galaxy A21s. By the way, this works also for the Redmi Note 10S. If you want to resell the phone or give it to someone else, please remove the google account first (Settings - Accounts and backup - Manage accounts - &Google-Account&- Remove account - Remove account - &phone PIN, in case you have one&or disable the "Find my Device"-option (Just go on Settings - Google - Security - Find My Device - Off it in the blue bar) I have used a Samsung A21s for that video. Thanks for watching phonesandmore :-) Feel free to follow me :-)
