(Reuters) - Strong sales of 5G iPhones and services such as the App Store and Apple Music are expected to drive growth at Apple Inc, which reports results on Tuesday, but some investors will be listening to the company's strategy to ward off anti-trust foes.

The services business faces lawsuits, regulatory scrutiny, including from an empowered U.S. Department of Justice, and a raft of pending legislation in the United States and Europe to lower its commissions on apps and make other changes.
