How can I disconnect mt account on my Galaxy note 4 ?

[AC Question]

Hey,

The LCD screen of my Galaxy note 4 is broken. I want to sell it for cheap because I don't have the money for a reparation. I want to know if it's possible to disconnect all my account from Galaxy note 4(Google account, Facebook,etc..) from my computer or another cellphone. Or how can I make a factory reset withouth seeing anything ?

Thank you !

1. Settings/General/Backup and reset. Factory reset.

2. If the phone ends up in the hands of a good forensic data miner, the data is mostly recoverable, even if you reflash the ROM a few times. Smashing the phone with a 5 pound hammer, then baking the pieces at about 500°F for about 30 minutes will destroy all of it.
