I have a month old Fe and I noticed that it will not stay connected to 5G for longer than a minute even with full coverage ( 4 bars). It will quickly reverse back to 4G LTE. When I force it to connect to band 71 NR using samsung band selection app, it will connect to 5G sometimes. I know my area has very good 5G signal -76db, and 5G NSA works on other 5G phones. I did every single setting change that could be possible including factory data reset as suggested by Samsung rep. That did.not fix the 5G connectivity issue. Do you know why it reverse back to 4G LTE instead of staying on 5G?

5G is more or less only used currently when the demand is there on your data connection. If you aren’t downloading or streaming something that requires the extra bandwidth, your device will revert back to 4G LTE. In some cases, you can make calls over 5G but I have yet to have a call placed over 5G.
