  3. Great info! Thanks.
    I’ve a question regarding the code *#*#4636#*#*
    My phone was not with me for last 20 days, somebody else was carrying it. And I just got it back.
    So I am trying to access the history of App usage etc.
    I tried this secret code ‘ *#*#4636#*#* ‘.
    The menu ‘usage statistics’ show ‘usage time’ history of very recent, to be specific after the power on by me.
    I can see some history of ‘1-jan-1970’
    Do I conclude that my phone is compromised?
    Please help.

  4. The presence of “1-jan-1970” in the usage history of your phone does not necessarily mean that your phone is compromised. This date is often referred to as the Unix epoch time, which is the starting point for measuring time in many computer systems. It is possible that this date is appearing due to a software glitch or an error in the system.

  5. Hi,

    I tried all the aforementioned codes and I get various errors. The main one says something about not able to reach this number on Verizon. All others just come up with “connection problem or invalid MMI code”. How do I get by thus? Also, do you just type.the numbers and hit dial or am I missing something?
