I find vibration super annoying and utterly useless, especially in tablets. I want to totally disable or even destroy, if needed, the vibration feature or part of all my 6 Google Nexus phones and tablets, and 1 Samsung tablet.
Anybody can help?
It depends on the mobile. On Samsung Galaxy S7, there's "Sounds and Vibration" in "Settings".
For Nexus devices, you may want to check Change volume, sound & vibrate settings.
Install Vibration Tuner Xposed module (root required) after installing Xposed framework and set "global vibration strength" to 0%
.
Compatible with at least Android 5-7 (I don't personally own a device with Oreo installed).
