Edit-works much better since this post. Batt of the device is the problem ive noticed. Love the usage of this camera which the product itself will be getting 5 stars but the app needs some work. It hasn't crashed or acted strange. It is just incredibly slow/ laggy. Now I'm not sure if it's my setup with the Flir One Pro or the app itself. (Note 4 with USB-C adapter) but viewing the pictures when not using the actual camera seems to show its slowness which leads me to believe it's the app.

I upgraded to a new phone (Samsung A55) and now the Camera and App work flawless. I am so happy that I did not get rid of the camera

IT DIDN'T WORK STRAIGHT AWAY HERE IS ONE FIX THAT WORKED FOR ME. 1. Enable developer mode. -- Google your phone and how to enable developer mode. 2. Go to OTG Connection and enable it 3. Save 3 hours trying to figure this out... you're welcome

I use this app infrequently, partially because I know I am rolling the dice about whether it will work with my FLIR One. Currently, it doesn't work on Android 14- it is not connecting to the camera. But when it does work, it's great!

The app doesn't support the built-in thermal camera (FLIR Lepton 3.5). Phone: Black view BL9000 Pro 5G
