Can I make my iPhone vibrate louder or stronger?

I often have to turn my iPhone ringer off. This is ok when I’m at my desk because when it vibrates it is loud enough on the desk that I never miss a call. My problem is that when I am walking and have the phone in my pocket, I almost always miss the call. This is becoming a real issue for me and I wondered if I could make the vibration louder, but [this question](https://apple.stackexchange.com/questions/111921/iphone-vibrate-level) indicates not. I have an iPhone 6s on iOS 10.3.3, and that question is about 4 years old now, so I'm hoping things have changed. Is this still the case? If its still the case, is there any way I can make the vibration stronger or something?
