I am trying to figure out when my devices (tablet, tv dongle, etc) were activated. Is there a place (in google account settings, device files, anywhere) this data can be obtained?
My devices are rooted, so I can use terminal access to read internal files if needed.
Some suggestions in the net say to find the first day of data usage in the logs, but I want to find an accurate date (preferably a timestamp) of the device activation.
I can't seem t be able to type dialer codes in a tablet, there's no phone app. Also this question is about android devices in general, not only phones.
