One thing I've noticed is that notifications cause the phone to vibrate when in a call. This wasn't the case with a stock Marshmallow. Is there a setting that can be adjusted rather than removing the notifications system wide
I just did a read write test on the internal SD and I think before I was getting about 150MB/s read and 40MB/s write on MM. Now it's 190MB/s read and 60MB/s write.
Just some numbers to backup the speed increase.
