Galaxy s21 leaks and rumors

[dkyeager]

To hunt for n77 with US Mobile black sim, a Verizon MVNO, with the latest factory unlocked release, only allow for band 66 and n77 using the the Samsung Band Selector app or equivalent. if you allow n78 as well SCP and cellmapper will fail to see it.  Of course you can also tell by doing speed tests, which are basically needed to trigger it.  Open to suggestions on less data intensive methods.

Yeah, I saw that.  Good stuffs.

Yep, don't notice any difference yet but I'll try tonight when it's dark out.

Does anyone know what kind of CA the S21 will be capable of when T-Mobile deploys N77?  Could we see something like 100Mhz N41 + 60Mhz N41 + 40Mhz N77?

Not sure if it supports N77, I don't see it enabled.

Yeah, it's not enabled.  But I think the phone supports it, after a software update.

Correct, both n77 and n78 enabled on unlocked version, T-Mobile MVNO sims support both.

Interesting, I have the VoNR option again.  I know I looked right after the May update, but I didn't see it.  Now it's there.

This is correct, it appears that Samsung is disabling the menu that the app served as a shortcut to. It looks like on TMo models, *#2263# still works for band selection though.

Good to know. This actually looks nothing like the screen I remember. Is there a guide on here somewhere, or "just Google it"? 😁

It is pretty easy to use, once you get the hang of it. For example, to select a specific LTE Band(s)

Click on [7] --Clear selected bands
Click on [5] LTE Band Preferences
Click on the specific band(s) you want to enable. 
Click on [F] Go Main
Click on [9] --Apply band configuration

The same holds for NR5G, just you would click on [5] NR5G Band preferences instead of [5] LTE Band Preferences

To re-enable all bands:
Click on [8] --Select all bands
Click on [9] --Apply band configuration

yup, i manually updated through computer.

hate that I cant use samsung band selection anymore. It forced the bands better than the dialer code way.
but I rather have the security updates anyway.
