I live in Oakland, CA where there is good 4G service. Yesterday drove to another area of Bay Area where there is no 4G and switched my network mode from CDMA/LTE to CDMA only. I have read in various forums that doing this is a good idea help with battery longevity. When I came home I switched back to CDMA/LTE but have not been able to get any 4G service since. I have rebooted several times with no luck. I called and spoke to tech support tonight and they couldn't do anything other than submit a trouble ticket. Evidently there are no network issues in the area. On another forum I was told that an imminent software update will help with this issue, but no further details were given. I will also say that I dropped the phone yesterday and don't know if that would contribute to this but everything else works fine and I don't recall the 4G going out right after I dropped it.
Hoping to get some thoughts on what might be going on.
Thanks.
