Well, there are limited number of possibilities, so they could just try process of elimination.....heh...

Washington (CNN) -- An FBI employee shared confidential information with his girlfriend, who was a news reporter, then later threatened to release a sex tape the two had made.
A supervisor watched pornographic videos in his office during work hours while "satisfying himself."
And an employee in a "leadership position" misused a government database to check on two friends who were exotic dancers and allowed them into an FBI office after hours.
These are among confidential summaries of FBI disciplinary reports obtained by CNN, which describe misconduct by agency supervisors, agents and other employees over the last three years.

You must be thinking about a simple iPhone unlock. There are only 9,999 of those. This is a smarter Android phone that allows a larger number of digits and/or text. But the phone in the article uses Pattern lock which is a totally different type of locking mechanism that could have many more permutations than a 4 digit pin code.

screw how many patterns there are, this is infamous fbi! dont you think if the fbi simply cant hack and crack an unlock like that, we must be paying too much for underqualified work? lets not even mention national security! maybe they want a safe and legal means of getting what they want, as not to be screwed by a pimp who can afford an amazing lawyer in court (OJ-style) but i could be wrong

4 digit pin lock possible combinations: 10,000
Pattern lock possible combinations: 389,112
They'll be guessing for a while

How? Isn't dragging to a circle just like tapping a pin character? Enlighten me.

An android unlock pattern can be equivalent to 9 digits long.

Your numbers are off. There are 986409 permutations. But I agree they will be guessing for a while approximately 68.5 days.
362880 + 362880 + 181440 + 60480 + 15120 + 3024 + 504 + 72 + 9 = 986409 permutations
986409 permutations * ( 15 seconds timeout/3 entries + 1 second pattern entry) = 5918454 seconds
5918454 seconds = 68.5 days

10,000. Zero is a number too.
0 0 0 0
0 0 0 1
0 0 0 2
0 0 0 3...
...
9 9 9 7
9 9 9 8
9 9 9 9
Incidentally this phone in question does not have whole image encryption (or more specific, it's commercial if that's the case) and seed brute forcing is much easier to do... so this article simply demonstrates the FBI really sucks at technology. They refuse to outsource to people like us because that's too expensive and they are very paranoid about security and civilians are the devil as far as that's concerned. So if you have a clearance and have been doing gov't contracting and are with a vendor they can use you but that's VERY expensive.
Bottom line, they take some CPA with a sidearm and "promote" them into a technical position. I actually dealt with their cyber crime agents before with a client and it was an absolute joke how stupid the two guys were.

If he used only 4 circles, then there are only 262,144 different combinations.

Gotta be at least 4 digits....knocks out 585 of those combinations, I believe that gives 985,824 lock combinations.
