I have a Galaxy Nexus. However, I know someone that is having the exact same issue that has an older Android phone.
The account I want to remove is not the Google account. We have Lotus Notes Traveler installed. Recently there was an update and that's when the problem started. I am unable to uninstall the app because of the account it uses. When I try to remove the account it says that I cannot remove it without factory resetting the phone.
Neither one of our phones are rooted.
Is there some way to remove the account without resetting the phone?
