If your phone supports it and you haven’t already I strongly suggest encrypting it and setting your password to “i_am_batman”. This way if you are ever swept off the street into an unmarked Econoline van and taken to a temporary Federal interrogation facility and they ask you for the password you get to lean in real slow and tell some secret agent shithead that you are in fact the batman, and realize every 8 year old boy’s dream. Doing so has the fortunate side effect of further obfuscating the identity of the real batman by introducing a wild spike it false potential IDs.
This is of course only if you don’t actually have secret documents on your phone, then it’s probably not such a good idea.
