Description FeRD (Frank Dana) 2022-05-21 00:27:00 UTC 
Apparently, detecting 5G network service[1] is more difficult than previous levels. Many 5G devices will report their network connection as TelephonyManager#NETWORK_TYPE_LTE. The actual state of 5G connectivity is only accessible by using the new (Android 11+) TelephonyDisplayInfo[2] API, where an "override" network type can be retrieved for display use.

Without access to that additional data, many US devices which provide 5G service via enhanced LTE will be reported as having only 4G connectivity.
