Calls 4G not working
#1
Hi,
I noticed a problem with making calls when mobile service is 4G. When I tried to make a phone call it ended quickly. When I switched to 3G it worked. On my android phone when I was making calls it automatically switched to 3G every time (only during a call). Is is a carrier thing? Maybe It would be nice to add this automatic switching feature like in android devices.

do you have 4g only mode? if so, switching does not work.

in my knowledge switching should work normally on eg25-g modem chip. maybe you should re-initialize volte settings just in case. https://wiki.pine64.org/wiki/PinePhone#VoLTE

for volte, lot of things could go wrong. device may not have support, carrier does not have support, device may have blacklists for not supporting certain carriers (referring to that android device), or carrier may blacklist devices (particularly in u.s.).
