Samsung Galaxy Note 3 — facebook replaced by an image of the Android robot

has anybody else had this problem, no longer have facebook.

i do not want to active the droid robot in case it crashed my phone, a friend had the same problem and he had to do a restart.

ok have found out what the problem is....(red Face)

somehow facebook had been un-installed.?

did a couple of virus scan on my phone and had a couple of bad programs and deleted them.

have now installed facebook and everythin appears nominal...heheeh
