Deleting data before selling an Android(Samsung) phone

[Anonymous]

Hi,

 I want to sell a Samsung android phone.

How can I delete all data permanently before selling it?

Is there a way to completely delete all data?

I think Factory Reset.

factory reset

once factory reset and for more safety after reset use for few minutes like capture photos and then again reset
settings> general Management >reset >factory reset

Factory reset is the only option.

Factory reset through stock recovery. Good bye and enjoy your new device 👍

Do a factory reset through settings. It's much more easy and convenient. It is more than enough and as Ehsank said use your device after reset. This will overwrite some data on your storage and anyone won't be able to retrieve any data but I don't think that is required. Just factor reset and you're good to go. 😊
