Mobile phone laser falses

During the last few weeks I am experiencing A LOT of laser falses. I’ve been using the very same phone, the very same windshield mount and the very same V1 for the last couple of months and I am wondering what might be the (software) cause of this, could this be some new JBV1 parameter in the settings or something? Falses are definitely caused by the phone because when I remove it from the windshield false laser alerts immediately stop.

On a separate note – why don’t alert maps (CSA on Google Maps) appear anymore below the alerts list?

Those increased laser falses are likely due to the proximity sensor. Have you begun to use face recognition or any similar "no touch" features?

Yes, I've always been using the iris sensor of the phone. But have never had similar issues until a few weeks ago. So is this some new sensor related feature of JBV1 and do you have any ideas how to solve the problem?

If it's a JBV1 change that might be causing it, I'd say it's probably the "in pocket" mode. Perhaps @johnboy00 can tell you much better than I can. :)

Try lowering the brightness on your phone display or moving it further from your radar detector. Its the flickering from the refresh rate that causes false laser alerts.

I have disagreed with BestRadarDetectors on this concept in the past. I think I still do. But...

@ori, if you have a way to cover your proximity sensor (electrical tape or black construction paper) without affecting your screen brightness; it seems like you might be in a good position to test this. I'd do it myself if I had the issue. :)

I'd love to see BestRadarDetectors proven right and me wrong on this. I say it's all about the proximity sensor and Infra Red.

We have done extensive testing. The refresh rates happen so quick you cant see it with the naked eye but the laser receivers see the flicker and interpret it as a laser pulse.

Yeah, I remember that and understand about refresh rates. It's not a big deal, but as I'd said, I have disagreed with you in the past on this. That very well might mean that I'm nowhere near the level of understanding on this issue as you. :)

Can you tell me (just to eliminate a possibility and put this to rest) that you are sure there wasn't an IR device along the edge of the screen(s) tested?
If you are sure of that, I'll accept it. :)

Yes, In our testing even vehicles built in Navigation displays would cause false alerts. Radar Detectors unlike Jammers don't have false filtering to analyze the pulses to determine that they are not false alerts. The receivers are not the best on radar detectors and driving through even a group of evenly spread out trees on a highway with the sun passing through can be seen as a false laser alert. Lowering the brightness on the displays will help.

Accepted. Thanks BestRadarDetectors for the clarification!

For my Galaxy S9, I would get tons of laser falses depending on the brightness and angle of my phone screen and angle of detector. It usually happened when dark, too. Try adjusting the angles of the devices and you should be okay. And, it has nothing to do with anything outside of the RD or the phone.. except for the fact by running an app more, your phone screen would be on more.

I was getting continual laser falses when I changed the position of my phone (Samsung S4) on the bike. It sits ahead of the V1 under the flyscreen.
I covered the proximity sensor with tape - no more falses.
Fairly definitive in that case.

So, this must be the cause. Any options to disable this sensor in JBV1 rather than using those good old school technique? :)

Apparently not in that phone. Turning off proximity sensing only turns off any responses, not the sensor. I believe you have to root it. Whatever that is.

It's rooted. What setting should I change in JBV1 (or anywhere else)?

Sorry. I don't know, it's in the phone system I believe. I googled to find out how to turn it off, but don't have the info anymore.
