I understand it now, thanks Usman!

I get your point because top selling is quite common and natural, but I tend to think "top" is modifying "Brands", and top's role in this sentence is just the same as those of "mobile phone" and "selling" which are playing as adjectives

Thank you Robusto! your comment is far beyond my expectation. hope you have a good day!

Thanks so much Peter, no wonder I feel something "not natural" in my sentence which is the second case that you mentioned.

Thanks, your answer is like a mind opener to me :) , is it too formal to use in an essay? I mean I kinda feel that it is more proper for more formal writing such as a scientific article or things like that.

Million thanks @AliAf. Your explanation is very clear and super easy to understand. Yet I am a little confused with the case of "dominate". dictionary.cambridge.org/dictionary/english/dominate dictionary.cambridge.org/dictionary/english/predominate. The second meaning of "dominate" seems to be similar to that of "predominate" which is "the largest, most important, or most noticeable part of something". It makes me wonder that if they can be interchangeable in the case that what I mean by "dominate" is not "to rule or have control" but "to be the largest, the most important"
