Can you increase vibrator strength on android devices?

Is it possible to increase the strength of the alarm vibration?

from API 26 onwards, you can change the strength by setting the amplitude of VibrationEffect

https://developer.android.com/reference/android/os/VibrationEffect.html

simply create VibrationEffect effect = VibrationEffect.createOneShot ( milliseconds, amplitude);

and then set the effect in the vibrator instance.

vibrator.vibrate(effect);

more details here

apparently not,

under android.os.Vibrator, you can set the pattern as well as the duration

vibrate(long[] pattern, int repeat)

vibrate(long milliseconds)

my guess is that different patterns can be used to "simulate" a stronger vibrate. (on,off,on,off) rather than (on, off, off, off, on).

also a disharmonious pattern may be more effective than a pattern with a fixed rhythm.

The Vibrator Class does not allow for this, you can only set the duration.
