I read the panel at the right, but didn't click through to "learn more about it". I presume that the ability to make calls is covered by the item "Quectel EG-25G with worldwide bands" (by a process of elimination). I think my GalaxyY is "quad-band", which allegedly covers the UK and US, though the latter in untested as I don't have a loose US SIM. Are there many more bands? > The PinePhone has 6 physical killswitches: > > Modem: On enables 2G/3G/4G communication and GNSS hardware, > off disables. Presumably this is what they refer to as the "LTE/GNSS switch". Obviously I'm meant to know that it kills EG-25G too. Naturally I've heard of 5G, though I have no idea whether my phones are 2G or 3G. EG and 25G don't seem to fit into this scheme of things. I guess I have to settle down with a dictionary of acronyms. > WiFi/BT: On enables Wi-Fi and Bluetooth communication > hardware, off disables. > > Microphone: On enables audio input from on-board microphones > (not 3.5mm jack), off disables. > > Rear camera: On enables the rear camera, off disables. > > Front camera: On enables the front camera, off disables. > > Headphone: On enables audio input and output via the 3.5mm > audio jack, off switches the jack to hardware UART mode. > > Just in case you need a serial port, of course. Interesting. So sleeve is ground, and Ring/Tip handle RX/TX? A handy mnemonic there. My GalaxyY has an FM radio, as does even my Nokia C1-01. Is this feature completely passé nowadays? Cheers, David.
