Same for me, 99% of the time, my Note 8 is smooth as butter. However, when I least expect it, and when I need it the most, it would lag, freeze, or would require a restart. Something odd I found with the device maintenance recommending to restart the phone periodically as a way to keep it running at peak performance. Either way, love the phone, I really wanted to go for the pixel 2 xl before purchasing the note 8 due to the pure Android experience and was hoping for an apple like experience on - frequent updates, good support, and best camera. I starting to realize how reliant I am with Dex and other features I'm enjoying with the Note 8.
