I whined and got some answers:
I am sorry to hear that you are having problems with the Fenix 8 AMOLED, I just have a few questions to better assist you with this issue.
- Regarding the sensor cover color we are grateful to have enthusiastic customers who care about our products. If you would like to submit an idea, to our innovation team please see the link below. Unfortunately that piece cannot be replaced at this time. https://www.garmin.com/en-US/forms/ideas/
- There will be more watch faces available in Connect IQ if you do not like any of the ones that are built in.
- The buttons did change on this watch due to the dive abilities of this watch, so they might take some getting used to. There is a calibration.
The following steps will allow you to calibrate the buttons of your watch and possibly resolve the button issue you are experiencing.
- Plug your watch into a Windows PC or a Mac that has the ability to read MTP devices (a third party program may be needed for your Mac to see the watch as a drive).
- Locate the drive for your watch on the computer, and open the drive.
- Place the KEY_CALIBRATION.BIN file in the Internal Storage of your watch. It should not be placed in a subfolder.
- Disconnect your watch from the computer.
The watch will go to a button calibration screen. Press each button fully a couple times. A green check will appear when the button is calibrated.
After calibration has completed, turn off touch on your watch, and test the buttons to ensure they are working.
If the buttons are still not working, let us know.
- Do you have a video of the lag you are seeing with the touchscreen that you can provide? Sending a File, Folder, Photo or Video to Garmin Product Support
- Can you explain further your issue with the display? Do you have the watch set to auto brightness? Display and Brightness Settings
