Strange .txt file that has the names of different presidents inside the android system folder
I found a related github repo but don't know if its official or from some ROM developer. From the source the file heads_of_state.txt is listed under IME but has been removed in the latest commit (the only other commit). The commit message is "Deleted uneeded LG's Calibration apk". I can't conclude anything from this but maybe this will be helpful.
