Narrative:
On the olaaa 1 arrival into lax we experienced wake turbulence caused by [a preceding heavy jet]. We were just getting vectors for the visual 25L. The wake turbulence caused a rolling motion to the right where the airplane [gave] the bank angle warning and the autopilot kicked off. I was the pilot monitoring and reached simultaneously with the pilot flying (captain) towards the yoke. We advised ATC and they gave us vectors and stopped our descent. We both thought it a [was] good idea to advise the passengers we were under control. We both thought it a [was] good idea to fly slightly above glide slope. It was VMC conditions. Whenever a B737 is following something bigger; we should be advised by ATC especially when we are that close and coming into an arrival [on] radar vectors from different directions.
