My phone constantly sets off my laser detector every time it gets too close to it?

[CeeTee23]

I asked when i first got my phone but got no help from samsung..does anyone else have problems with 24 ultra constant setting off my laser detector if the phonw is anywhere near it?? I have to keep my phone in my pocket or it sets off the detector NONSTOP 😒

What's a laser detector?

Um its a lil box on my dash that tells me im bout to get a ticket..so when it goes off its very scary.

Radar detector

Er..., LASER obviously isn't RADAR, but since you did make the subject radar but only refer to LASER in the post body I'll assume it's possible the detector might detect radar signals since it's the more common used for vehicle speed detection so it's worth saying a lot of radars operate in bands just outside the wifi channels. But, if the S24 Ultra wifi is the way it is on the S25 Ultra then I understand it defaults to wideband operation even if a single non-radar channel is actually being used for wifi comms. You might prove wifi is a factor by turning off the phone wifi functionality and taking a drive. If it proves effective you might be able to avoid toggling wifi on/off when entering/exiting the vehicle by turning off Ultra-wideband (UWB) mode in Settings->Connections but I suspect you might be stuck having to disable phone wifi when driving (possibly also BlueTooth but that's less likely). If it's just a cheap laser (/radar) detector it may be too sensitive to signals at the wifi band edges when the phone and detector are close to each other. NB: wifi isn't at any of the light frequencies used for LASER so this post is pure speculation based on the title but not the body of the OP but may be worth a try.

Im sorry. Let me clarify. I have a radar/laser detector. It alerts my laser and it says, maybe 228 as the "band" of laser.? If i have the phone facing up anywhere in the front seats or dash, it is NONSTOP alert. Even if i turn it face down on my lap, it still usually alerts every few seconds. If its inside my pocket, theres not a peep. I think i even sat it in the back floorboard and got quiet. I feel like it could be face detection lasers causing the problem so i enabled an option in developer options called sensors off for my pull down menu and that nearly renders all radio communication null so i hoped it would eliminate my problem but no such luck. Thanks for the suggestion tho..

I'd do as the previous poster suggested and turn off the wifi when driving - you don't need it on anyway unless you have a hotspot in your car. You can even create a routine for it: if driving or connected to (car name), then wifi off.

Oh and i rarely ever have my wifi on. I dont have wifi and have an unlimited data at&t cell plan. Srry i didnt mention that in my response to her comment earlier.

Bluetooth FHSS around 2.4GHz might be enough to fool a cheap radar detector but I'd have expected the low power level and frequency hopping to make it less likely than wifi, but you should test with wifi and bluetooth off. Also, at least one of the S24U cameras supports infrared laser autofocus. That could only be protected against with the phone in a closed cloth pocket. Whether or not you have a camera app running, I wouldn't assume it's idle at any given time.

I just checked the US cellular bands and it is possible that 4G and 5G voice, data or connection maintenance could be interpreted as a radar source by a cheap detector but I'd expect connection maintenance to be periodic during "idle time", i.e. when not in a call or actively using internet. You could try turning off mobile data as well for a test drive in case you have a background app that uses enough internet to prevent the cell signal going idle.
