Is it happening all the time, in all drive test, in all regions?

It could be due to sudden change in radio conditions like you are driving urban areas and sudden turn around the roads will cause this.

If this comes and goes then it shouldn’t be a problem.

But if it for a long period, such that it cause call to drop or noticeable pause, then worth investigating.

But it’s like due to radio conditions.
