identify this movie - A.I. dies and makes all phones on Earth ring in unison at the end - Movies & TV

Can you help me identify the movie where a computer, an
artificial intelligence, dies and makes all phones on Earth ring in unison at the
end?

Here's a list of memories I have from this
movie:

• Computer falls in
  love with computer scientist's
  girlfriend



• Computer competes for love of
  girl


• Computer scientist walks down stairs with girlfriend
  held off the ground in his arms trying to hide her escape from the computer, but the
  computer senses the weight difference from the sound and detects what is
  happening


• Computer makes a love song and performs it for
  the girl


• Computer's love song shows lack of understanding
  love, and comes off sounding very technical, for lack of better way of describing
  it


• Computer eventually commits suicide by making an
  electric surge hit itself


• Computer makes all phones in
  the world ring in unison to signal its
  death

I may be off on
some of these points. In fact the phones all ringing in unison might be from a different
movie, such as The Lawnmower Man.

Electric Dreams is a 1984
British-American comedy/drama/romance/science fiction film set in San Francisco,
California, that depicts a love triangle between a man, a woman, and a home computer.

The
ending isn't "cell phones" but a song played on radios all over
America.
