UPDATE (04/07/2022): This is the response Samsung gave about band selection being disabled. It won't be coming back it seems.

Ever since I had the Note 10+ 5g, I had been able to use the band selection app to open the hidden menu which would allow me to select which bands to connect to and which bands to avoid. This was particularly important as Band 3 (1800Mhz) would give me the worst speed (~0.5 - 4 Mbps) and is at the same time the band/frequency the phone connects to constantly since it has the strongest signal strength. Band 3 also prevents my phone from connecting to 5g in my weakly coveraged area which enabled me to fix my several year long issue with terrible speeds giving me speeds up to ~200+Mbps. 

I just received the May 2022 update for my phone and I decided to update due to the camera stability improvements. After completing the update I notice that my phone is no longer connected to 5g. I check the band the phone is connected to and notice it to be Band 3. Thinking I may have forgot to turn off the Band 3, I try opening the band selection app to which it gives and error that it can't find the hidden menu.

I've come to know that this issue is widespread on the latest updates for most if not all the galaxy phones.

I don't know why the menu has suddenly disappeared or been disabled, but it is a very important feature for me and many others. I see no reason as to why this feature would be made inaccessible on Samsung devices since it isn't destructive but rather a really useful feature for many users.
Could someone with a better understanding, or better yet Samsung themselves please explain what's going on?

with the new update alliance stopped working for me. ***** samsung u will not allow us to downgrade either. i think better to move to chinese manufacturers like xiaomi where changing band is very easy. i know samsung has been bribed by 5g telcos to do this so that they can force us to buy expensive 5g data plans but u know what samsung ...u 've been loosing ur costumers.

As the Alliance Shield X option is not working for now as Samsung has revoked their knox keys, I have found a working option for now. For this you need a pc/laptop. Find a working version of "Shannon DM" tool. Connect your mobile in "RNDIS+ACM+DM+ADB" mode using *#0808# option in your mobile dialer. Then go to "hidden device menu" from Shannon on your pc. Click on network setting>sim slot 1/2> LTE or NR> band selection> choose the desired band from the list. Thats all. Have a good day and cheers.

As far there is no access of samsunghiddennetwork setting direct from the non-rooted android device, you need the shannon dm tool to gain access of the network band. If you know which band disturbs you more, then just deselct it. For my area, band 40 is used for high speed and lesser coverage. But the band is so overcrowded that i use to get the least speed. Thatswhy i choose to disable that band most of the time. I have tried this method for multiple samsung devices. Works like a charm. Caz, the tool is the samsung's proprietary software and can access everything regarding network.

I think, I should raise a compain in consumer court against samsung, because in july update this issue started happening that I started facing issues with 4G networj connectivity. where update states only security patch where nothing was mentioned related to Network band or speed or nothing like that.

you will be punished.
