In general, the keyboard is excellent. However, I recently moved to Samsung and the app doesn't work very well on there. Especially regarding the sound. For some reason, the touch sound is always on max volume and there is no way to turn it down. The slider they have there doesn't work, no difference between 1% and 100%. Unfortunately, when you contact Google to fix this issue, they blame Samsung (even though it is a Google app), Samsung, obviously, say the app is Google.
