Hello,
I have a Fenix 6X Pro solar and never had problem with.
A day it dispalyed the watchface from the Tactix even i never downloaded it, and when i use any button from the watch it displayed some irrelevant informations everywhere on the screen
It didn't happened after a synchronisation or else.
I can also go in the system and reset menu, what i've donne multiple times, no effect
I also erased all the files in the watch via the file explorer from windows but i didn't work either.
I've seen on youtube that you could allso make an hard reset by presing simultaneously the START and BACK buttons and then the LIGHT to reboot the watch but i didn't rebooted so i'm not confident with that procedure.
It doesn't sinc anymore
If someone can help that would be very nice.
Xavier
