My Samsung phone lost the Verizon 4G/5G icons a few months ago and began displaying the default Samsung icons instead where it displayed a 5G icon nearly all the time. However, upon more careful observation I discovered the phone is not actually in 5G mode most of the time:

It was only when the 5G icon "lit up" that the phone was in 5G:

Yesterday I installed the One UI 6.1 update and this brought back the Verizon 4G/5G icons. However, now there's just the Verizon 5G icon on my phone constantly now, but my phone is still almost always in 4G mode:

What gives? The Verizon icon doesn't light up like the default Samsung icon does, so now I really don't know if I'm in 5G or not without speed testing. And thanks Opensignal for "keeping your carrier honest"! Ookla speed test app doesn't know and thinks I'm always in 5G so I get the craziest variation in speeds anywhere from "dial-up" to "my cable ISP is scared", haha.
