In the Vancouver, BC area I find my phone will drop to 4G service - and not cycle to 4G+ or 5G. This happens a lot and for those that may not know, 4G is really slow. I'm a gig worker at night and it's a pain in the **bleep** to upload photos for proof of delivery when the phone is in 4G mode
Found a solution. I made a bixby routine which changes the cellular connection to LTE mode. I made a shortcut using a Bixby widget so that I can hit the home screen, tap to start the routine, wait for phone to cycle the radio and reconnect to the Telus network, once I see it gas shofted to LTE Pro, I tap the bixby widget again to end the routine and turn 5G mode back on.
Would be better if my phone didn't get stuck once I found myself in 4G only, but, it's a quick way to cycle the cellular connection and get back to full cellular speed on my S22 Ultra
