Allright, therm viewer activated properly today- odd, it took a while...
I did not get a email response though, from Jinhua.
This is the sort of thing that has me worry lol that i need to buy a bunch of phones and register my cameras to them with all the various apps for the cameras , since nothing quite compares today(i love my phones with therm app plus, which has visuals that the default app, and thermviewer doesn't even fully match- and no thermal camera + software today i see elsewhere looks as good, - gotta preserve the abilities we have since it apparently doesn't always get better with time)
