Display glitching after turn my hand

That looks like the 265? You posted in the 165 forum. I suggest that you rather post in the 265 forum, along with details of what firmware version you are using.

I think you should also contact Garmin support directly. They don't seem to visit this part of the forum very often.

Nah it's 165 music. But thanks for your advice

This is the exact same issue I have been complaining about on my recently bought 165! Thanks for the video. 

This is the exact same issue I've been complaining about on my forerunner 165. Thank you for the video. It clears when you press the light button.
