I am confused about the grammar related to "in different ways"?

I am going to make up two sentences with "in different ways" below.

(1) You examine this issue in a very different way from I.

(2) As an experienced retail manager, my uncle has different ways of dealing with customers from the less experienced assistant manager.

My non-native English speaking friends and I learn English from one another. We all agree that these sentences are grammatically OK. However, my non-native English speaking neighbors have a different opinion. In (1), they think it should be "different way from how I do". In (2), they think it should be "different ways of dealing with customers from those of the less experienced ...".

We, all non-native English speakers, have different opinions about the sentences. Are the original sentences OK? Thanks you very much, native English-speaking teachers.
