It appears I can factory reset old phone with cracked screen on find my mobile. I already have set up new replacement s20 and registered the new device. Both are viewable in Find my mobile. Will deleting or factory resetting old phone disable my new device? I need to ensure that the device is wiped before sending it back but I don't want to have to set up new phone again.
When you use Find my mobile, it will only reset the device you choose, so as long as you choose the correct one (Use play a sound/ring feature if both devices have same name), the other devices will not be affected.
