<Cell phones have just started being used more often (recently/these last years/lately). >

Why do you need "just + V", which means recently, and also the adverb "recently" in the same sentence?

Yes. Without the been.
Not a pretty sentence, though.
A sentence may have a theoretically correct passive, but still be a dog.

<A sentence may have a theoretically correct passive, but still be a dog.>

But there are mongrels and pedigrees. I think this is the latter:

"Recently, cell phones have been used more often."

People have started using cell phones more often recently

Yeah. The sentence is clumsy, i agree. I just wanted to know the passive when there are two verbs in a row. So that "recently" doesn't really matter.

I wonder if the same thing happenes with a Past sentence.

Cell phones started being used more often. Is it correct?

Yes, it is.

<Cell phones started being used more often. >

It's correct, but it doesn't show us how recent the action is.
