I'm planning to sell my old phone and I'm a bit unsure about how to properly reset it. I've already moved all my important files to my laptop, but I want to make sure that all my accounts, especially social media, won't be accessible from the phone anymore. Will just resetting it be enough to wipe everything clean? Thanks for any help!

Yeah, all modern phones are encrypted. When you do a factory reset, it deletes the encryption key, making it impossible to recover your data. So, you should be good!
You're right! While factory reset removes the encryption key, some still worry about data recovery. Your method of recording a video to overwrite data is clever, but keep in mind that the encryption generally protects against most risks.
If you're selling it to an average person, a factory reset should be sufficient. However, if it ends up in the hands of someone skilled in digital forensics, they might be able to recover data. To be extra safe, I recommend resetting it, then recording a high-resolution video until the storage is full, and then resetting again. This can help overwrite existing data.
To reset your old Android phone, just go into the settings and perform a factory data reset. This should clear everything on it.
