will this work if i crash my drone?

and also why do i see red in my camera view (the live one i mean)?

Yes, Care Refresh generally covers crashes due to pilot error but you should review the details. What seems to be the most common surprise for people is that you have to recover and send the crashed aircraft back to DJI to get a replacement.

You need to set the Focus Peaking option to Disabled.
