Help I used my gmail acct. on friend's phone to DL app from playstore now my contacts are on his phone :(

[Whoodah Thunkit]

my friend wanted me to put some files from my computer on his phone so he dropped it off and will pick it up later.

but i had to install an app and he didn't have an account set up when i went to the play store so i logged on with my account. well, now it synced my contacts on his phone along with his contacts!

i'm hoping there is a simple way to maybe "unsync" the contacts that were just synced to his phone.

can anyone help me?

thanks.

Is your gmail account listed under 'accounts'? I would check to make sure and delete it first and foremost. I' m not sure if there is a way to undo the contacts other than deleting them one by one. Hopefully someone will come along with a solution for you, good luck!

Addendum: I'd check his emails too to make sure they aren't on there as well.

I don't know for SURE, but I suspect the only way to get 'your' data off his phone is by doing a factory reset. Or, as msndrstood suggested, deleting things one by one. Either way, you're looking at spending some time to get things cleaned up.
