Clive (yt: bigclivedotcom) uses his CAT and now Blackview phones to check electronics for hotspots, etc. He reviewed them in depth:

- "One year test of the CAT S61 thermal imaging phone." https://www.youtube.com/watch?v=Ex7mNzhZN9A

- "Independent Blackview BV9900 Pro 4-month review (non shill)." https://www.youtube.com/watch?v=X5n7oE2K__4

I would love a phone with a FLIR sensor but definitely don't need it.
