I'm currently arguing a case where an authority claims that my sons phone was turned off at a specific point in time.
I have technical logs, serverside, that corroborate that his phone was active just around the time in question (5 minutes before and 4 minutes after the event), but I expect that with that they will then claim that his phone was just rebooting at the time.
Is it possible that I can obtain any kind of technical information from the phone, similar to Desktop Windows' Event Viewer, where vital system events can be seen? I've searched, but found no indication that it is possible, which is why I'm trying here.
(I've also contacted the phone company to see if I can get access to their logs as to whether the phone used their service at the given time.)
