The 46-year-old has rejected suggestions he has mellowed in recent times but admits he now prefers to keep club matters private
The 46-year-old had an infamous touchline bust-up with Borussia Dortmund boss Jurgen Klopp last season but has kept a low profile so far this term, though he insists his character remains very much intact.
"I've become externally quiet, but I've certainly not become calmer," Sammer told Bild Sport.
"When I see danger, I talk to people internally. Perhaps that's why people think I've become calmer."
The former Germany international also took the time to confirm his relationship with Guardiola is a healthy one, despite admitting both parties needed time to become accustomed to the new regime.
He explained: "Of course he [Guardiola] had to get used to me.
"With Andoni Zuibizarreta and Txiki Begiristain [directors at Barcelona during Guardiola's time there] Pep constantly had someone by his side. But the trust between us has grown quickly."
Bayern have started the Guardiola-Sammer era by racing to the Bundesliga summit, remaining undefeated after 16 games, and have a seven-point lead at the top despite playing one game less than their nearest rivals.
They have also secured their place in the knockout stages of the Champions League after topping their group, where they will face Arsenal in the last-16.
