My Gopro Hero9 works for a couple of years, then some lines appear on the screen. It was not damaged or similar, just appear. I had submitted this problem to GoPro Support, and I was in contact with them for a couple of months. First they told me that I need to send it with paying a fee to get the new one. After that they told me that I need just to send the device and they will replace it with a Hero10 and send me back. They also wanted from me to rate the service. I followed all the instructions for sending, and then I wait for 1.5 month to receive it back. And what I received was the same package that I have send. I realised that I paid the travel of my Hero9 to Venlo and back. After that I tried to reach them, but nobody call me or contact me on any other way. DO NOT TRUST THEM.
