2.) Change Hotspot Password on new Samsung Android Smartphones!
To change the AndroidAP Password on new Samsung Galaxy Smartphone, please open the main menu of your Samsung Galaxy, or direct open Samsung Settings then in Settings touch / tap on "Connections" and in next "Mobile hotspot and tetherin" and change the password optional the AndroidAP hotspot name.
3.) What should I consider when assigning / change the password?
To prevent unauthorized access, I recommend for each Samsung mobile phone to choose their own password
If all devices with the same password form the same network ID for the users, connection and system problems will occur as well.
Does not the new password work?
If the new password does not work, please create a new password. Make sure you use a consistent spelling when you set the password and login later. You may have used a different uppercase or lowercase character or randomly entered a space when typing.
