the touchpads atleast feel like the ones on the steam controller.
flickstick is a control scheme where your stick only controls the camera horizontaly, so if you push the stick down you’ll spin 180° if you push it to the right you’ll turn until your character faces to the right and so forth.
Definitely not normal.
I’ve got mine for 2 years now and could probably still count crashes like that on one hand. so if you are sure it’s not a faulty sd card or something like that causing this i’d send it back.
e: sometime ago an Update introduced Fan Curve settings, its a checkbox in the system settings titled “enable updated fan control”, some people reported higher temps with that enabled, so your crash might be the system powering down to avoid overheating, thats atleast worth a try.
