Suppose I lost my phone and I could use find my phone to find it. The problem is I don’t have my phone in order to find my phone with. I don’t have a computer I don’t have a laptop All I have is a phone. How on earth would I use find my phone to find my phone?
So, anyone with an android can let you use theirs and the “find device” app in guest mode. Your info won’t be saved but that option is there for exactly your use case
Nice
