Here in the UK not all areas have 5G. But if your using your phone as a Sat Nav and pass through an area that has 5G. you may notice you lose GPS signal.
It takes a considerable amount of time to reconnect.
Spoke to Samsung and they are aware of the issue (Although they kept me going through multiple testing processes before admitting and telling me this)
Chat Screenshot attached!
No idea what update will include this fix. It does mean though i will have to lock the device to LTE signal to avoid loss in signal when traveling and using my device as a Satnav!
