Hi, please PM me quick with your details. We use an over the air update server, if we can get your details we will push the firmware update to you. In the mean time if you can check your Network Mode setting, it should be on Auto
Nope, this could be a case of you been close to the edge of the cell, or between the edge of two cells - NSA handles this differently to SA. Lets see, i would recommend moving the router a bit, even 20cm could solve this.
Awesome, if you are in decent radio conditions then you can expect improvement when using SA. Please let us know how stable it is, from what we see its a big improvement! Let me know if you need anything else
You should never see both 5G and 4G lights on at the same time, it now defines which network you are on, so 4G light means you are on 4G only or 5G means you are on 5G only (SA) - should never see both lights.
