More likely you tapped the Recent button to show a list of your recently
used apps.  Like a MRU (most recently used) list in Windows, you can
clear it out.  That only clears THAT list.  It does NOT unload any apps.

It's a MRU list.  Not a task manager showing active apps.

You are asking in an Android newsgroup.  Android memory management works
the same way on all Android phones.  I don't know how iOS or other
mobile operating systems work (don't have those so haven't bothered to
investigate their memory management scheme).

Any smartphone vendor can customize the OS and screens however they
want.  That is how they differentiate themselves.  If they all used the
plain vanilla OS without any tweaks, they would all be the same phone so
the only factor in choosing one over another would be the hardware
(memory size, SD card capacity, speed, processor(s), camera features,
etc).  I don't have a Blu smartphone to know what they decided to shove
into their GUI.

To find out about how Blu customized their version of the Android OS and
what apps they pre-installed, read the smartphone's manual.

You did not mention you series and model so I cannot go read the online
manual to see what the broom icon does.  My guess is you tapped the
button to show the Recent list and at the bottom is a button to clear
that list.  On my Samsung Galaxy Core Prime smartphone, that icon shows
as 3 horizontal bars (representing lines in a list) with an "X"
character, meaning that will x-out (clear) the MRU list.

After a power up, the MRU should be empty until you actually run an app.
Not even background services that auto-load will show up there.  It is
an MRU of the apps that *you* loaded or re-accessed.  That's why I
suspect you only locked the smartphone instead of actually powering it
down since the MRU still has the same entries in it.

How do you power down your smartphone?  Do you press and HOLD the Power
button until you see a prompt asking if you want to power down followed
by another safety prompt to ensure you really do want to power down?
When it is powering down, does it vibrate just before the screen goes
blank to let you know, yep, the OS unloaded and the hardware will
immediately power off?  That's what my Samsung does.  I don't know what
your Blu phone does but it should be similar.  Just tapping the Power
button merely locks the smartphone, not power it off.  A long-press is
needed on the Power button to power it off.

My Samsung's variant of the Android OS clears the MRU (Recent) list on
power down or, probably more accurately, begins with an empty MRU on
startup.  Your Blu variant of Android might somehow retain the MRU list
across phone sessions; i.e., the MRU survives a power cycle.  That means
they would have to write it somewhere that survives a power cycle rather
than just retain it in memory.  Seems a waste to show an MRU for a newly
powered up smartphone before the user has had a chance to run anything
yet in the new phone session.
