What happens with the installed apps when you switch Google Account on a phone? I am going to buy a new Android phone.

I would like to give my current one to my wife when I do this. She already owns an Android phone so she has her own Google account.

I am just wondering what happens if I switch Android account to my current phone. Will she be able to use the installed apps or only the ones she bought also?

Or does she lose the ability to upgrade the apps, but can she still use the ones already present?
Apps are linked to the account that downloaded them, but Android has adapted, and will recognize the apps that are installed, regardless of which account is on the phone. This means:


Your apps will not be deleted from the phone if you switch accounts 
You will still be able to update apps
You will not be able to use any apps that were purchased through the other account. They will remain on your device, but most apps check for validation in the Play Store when they start, and will not allow you to run them if you have removed the account they were purchased in.


ALTHOUGH: You can use them if you leave the other account logged in on the device, they will just be managed by that account in the Play Store. You can switch accounts to manage apps for either by pressing Menu in the Play Store and selecting Accounts and choosing the account with the apps you wish to manage. Then choose My Apps from the Menu after you have switched accounts.
