how do I close the facebook account of someone else that is on my android

[Android Central Question]

I lost my phone. My wife gave me hers. We switched my number to her phone. But her facebook account is still on the phone. How can I cancel it and put mine instead?

In the Facebook app, go into settings and sign out of the account. You may also be able to go into the accounts section of the phone settings and remove the account from there. Another (arguably better) option is to do a factory reset of the device, but be sure to remove her Google account(s) before doing so or you'll have issues signing in to your account on the device when setting it back up.

Whatever you do, do not "cancel" the account, you'll end up making a big mess of things.
