How to Uninstall an application assigned to All Devices in phased approach on Intune for Android
Hi, We currently have a 4000+ device estate on Intune, mainly consisting of Samsung Android Devices. When we migrated our phones to Intune, we deployed Samsung Calendar as a "System App" to "All devices" from inside Intune as Samsung Knox has been set to hide all System Apps. We've now come to a point where we want to remove Samsung Calendar from all phones as the preferred option is to use Calendar from inside the Outlook app. However, we want to remove Samsung Calendar in a phased approach. The first part of this is pretty easy, we've created a removal group and assigned it to exclude devices from "Required" and include it under "Uninstall" - This ensures the devices we put inside the removal group will have Samsung Calendar removed and won't be included as part of "All devices" However, This won't stop new devices enrolling into Intune downloading Samsung Calendar as we've still got the "All devices" option under Required and we don't want to keep putting new devices into the removal group. I'm worried that if I remove "All devices" from the Required section, that it will uninstall Calendar from all existing devices (including the one's we've not put in the removal group yet), which makes our phased approach null and void - is this correct? I can't exactly risk trying it because by the time I find out, it will be too late. Any help and Advice would be great. Thank you.
