Sounds hear twice from 0.11.0 build 1 to 0.11.0 build 13. You can prove it destroying any block, like wood, dirt or stone.
My device is a Phone - Android - Sony Xperia M2 Aqua
My second device is a Tablet - Android - Woxter Tablet PC 97 IPS DUAL
It happens on both devices and also happens to many people.
Please fix it!
