When ever you open your phone it sends low burst radio signal that can be read over 100 meters.https://x.com/c10ned/status/1908305530038141290https://x.com/c10ned/status/1908305530038141290Any anons know why this is case? What's use case of sending such signal moment you turn phone on/login?
>>107856344To check what cell towers are nearby? I don't know.
>>107856356It's used 13 mhz signal nothing that correlates with cell towers it's same frequency that's used by nfc cards anon. You can literally open up a radio analyzer and figure out whether or not a room is occupied or not. Imagine being a burglar and you can scout out homes by laying this near a house to figure out what time of day they're most active vs not.
some IoT shit I assumei dont really know, there must be something cool you could do with this infohook it up to a shock collar that shocks you when you check your phone so you do it less often
>>107856344Is this done even if NFC is disabled?I guess its just searching for an NFC payment device upon unlock.
>>107856344Pay no attention to the electromagnetic radiation, goy, and take your meds
>>107856849>>107856706>>107856680>feds can literally track your behavior by detecting radio signals coming off your phone and make a personality profile of your phone usage , sleep hours and where you stay most of time.
>>107856344Seeing it is linked with unlocking the phone or turning on the screen it could be related to the starting of the display driver circuit that causes a burst of EMF in that frequency.
>>107856344Probably scanning for nearby devices in case you're using the feature to auto unlock in the proximity of certain other devices. It probably does this even if you don't use the feature because nobody optimizes their fucking code anymore.
>>107856857Feds don't need any of this to do that. They have access to cell towers. They can see where your phone is at all times if it's turned on, and can send requests to its cell modem including retrieving any file from the OS.
>>107856857>>107857124Yeah it's not really so much the fact that feds can do it so much as it is the fact that anybody can do it, easily. Same with WiFi motion tracking through walls. Anybody can do it with like $100 of equipment. Some script kiddie can watch you fapping through your walls without you ever realizing it
Former Android dev here. It's used for near field com, the nfc, to sync/wake your smart accessories like watches and so
>>107856344It’s for the british TV licence tax, so they can tell if you’re watching BBC or not from their van parked outside your house,
