I have an S500 that I use at a desk used for dispatching. Now and then if the phone is positioned just right it will randomly reboot the phone, access the call log, dial a number or even change menu screens when the two-way radio is keyed up. This gets worse if I set a handheld in proximity to it. The system we are on is a UHF using frequencies from 450.1000mhz to 468.9750mhz. I have found a way to mitigate the problem for the most part by not setting the handheld near it and rerouting the antenna coax for the two-way in a direction away from the phone but it still happens from time to time.
The phone is my only phone so I don’t have another to try it out with. The two way radio system is on a Kenwood Nexedge Digital Trunking system so it checks in with the control channel from time to time on its own.
Are there any other two-way radio users or Amateur Radio operators that have experienced the same thing?
