I have two calendar apps on this phone. The Samsung calendar app I can't delete, and the Google calendar app I can. They both seem to have the data I entered into the Gogle calendar, so guess both are synced to my Google calendar in the cloud. Can I uninstall the Google calendar app and just have one without deleting the entries that are in my calendar? I have a Samsung J7 that only has 16gb of storage and so I need to pare down the apps I've installed.
