    jujst got my R3 on monday and this morning was the second day of using it during my long morning commute. Today, as I was approaching a toll booth (probably about 0.2 miles away), my R3 went ballistic with a laser detection. Naturally my heart dropped into my stomach, and quickly decelerated, and continued approaching the booth. About 200 or so feet from the booth, the laser alert went away just as quickly as it came, I did an area scan to check for LEOs; nothing. at about 50 feet from the booth, it started to pick up a weak K-band signal, and everything seemed back to normal. Initially I thought it must have been something with the toll booth, but then when it went away before I even got to it, I changed my mind. I really had no clue. Now after reading this, Im thinking it may have been my iPhone X (iPX) which is mounted just below and in front of (closer to me) my RD. Right around the time this happened, the weather went from overcast to significantly darker, on the edge of what would be heavy rain in the coming minutes. So, now Im wondering if this wasn't the light sensor on the iPX. Or maybe it was some other sensor. The iPX has a ton of new sensors that previos models didnt have because of its facial recognition features, etc.

    Sorry for necropost, didnt feel worthy of a new thread

    Very possible it's the phone sensor, and there are some sensors around toll booths that can trigger laser alerts as well if it happens again in that same area its safe to assume it's the toll booth

    Toll booths have all sorts of things going on. Its definitely possible the Laser source is coming from there. You said it dropped right before your approach. Look for pole mounted devices next time your through there. Phones can also cause falsing as well as environmental conditions. Keep gathering data.

    now that i think a little more about it, on this section of I-90 in buffalo, right before you approach the toll booth, the Buffalo airport runway is just a 50 yards to your left. As you pass by, you can see a series of poles that run perpendicular to the highway (parallel to the runway) that I know to be the ILS, or instrument landing system, for guiding aircraft approach. However, these typically only use radio waves, not light. That said, maybe there is some component of the system that uses laser.
    Yeah, I'll keep an eye on the areas leading up to the tollbooth. Yesterday morning, however, it did not trigger. Like you said, I'll keep collecting data.

    I took my first long trip today with the R3. I spent 11 hours in the car with it and I am at the point where I have to turn Laser detection off. It went off constantly today. I have a cracked windshield and I am sure that it diffracts sunlight and is causing some of it. But even after moving it to another location away from the cracks in the windshield the false's continued. Mostly when the sun was at a low angle. I sure hope something can be done to fix this. My hope is that after the windshield is fixed it will help. For now I plan to turn off laser.

    Had my first false laser alert yesterday. I had pulled off and stopped on the side of a residential road to read an email that had come in. My R3 is mounted just left of rearview mirror high up by sunvisor. My IPhone X is mounted left side of center console by the handbrake in my 2005 corvette. As I left my phone in its mount but moved closer to read the screen my laser alert went crazy. Every time I moved away from the phone it stopped, every time I moved back to looking at the phone it went off again. I've done similar things before without it alarming so I don't know what made it different this time....maybe some environmental conditions of amount of light in the cabin.

    My iPhone is the only regular source of falsing. The funny thing is, it affects my Max 360c but my R3 doesn’t false. So it seems from our experiences it has to do with how close the phone is to the detector(s). My R3 is mounted in my top left of my windshield, while my Max360c is on a blendmount below my rear view mirror, and my phone has been on a dash mount towards the middle of my windshield.
