Getting 5G/VoLTE working on SM-N9860 (HK Note 20 Ultra 5G)

[kent800129]

here in greece the icon 5G appears but it has low speeds and also while it supports 5G the speed writes 4G LTE.

Please test the 5G in SpeedTest and open Service Mode to see the bands details while using the mobile data.
If the location you're in doen't get good and stable 5G signa strength
Then the phone will force back to use 4G.
You can check this in service mode.

5G working here with GIFFGAFF via the O2 network too. Be aware that not all 5G masts get high speed Internet. I was getting 20Mbps on three different 5G masts until finally getting nearly 300Mbps... Havent been able to test EE but should work OK. Three works fine too and high speed.

EE works fine with 5G now.

Hello everyone

I received a notification yesterday to do an OTA update to the latest firmware (TGY).

Having at last enjoyed 5G with EE (UK) thanks to the amazing work by @xUtsumi @kent800129 and @bocsta , I am reluctant to update in case Samsung takes back the whitelist option and blocks 5G once more.

Has any brave person tried it?

Thanks!

I applied the update yesterday, but did not check for 5G function on EE. Today I discovered that 5G had become disabled, but the whitelist setting is still available and selecting it does restore 5G on EE following a reboot.

Short test this morning....

Can confirm that updating is safe. You can still access UE menu and do the mods. I just noticed though that my 5G is slower. Maybe just an area issue. Will try a different location tomorrow. But it is safe to update.

 

[silmarils]

Thank you both @tdodd and @xUtsumi. Indeed the update brings back the whitelist but it can be removed as before.

Also good news, I don't notice any slower speeds, still around 300Mbps in my area. Happy days

Did you have to modify any settings to get 5g working on EE or was it just the new update?

I had to change the Whitelist setting to enable EE 5G. I've also made other changes in the past to things like MIMO and DRX and 5G Prune. I don't know if any of these are necessary for EE specifically. I would guess not.

However, I have actually reverted the settings to stock as I really have no need for 5G and I was suspicious that battery life was taking a downturn with all these tweaks. Maybe its in my imagination as there are too many variables to pin down a definitive villain, but the phone works well on 4G+ so I'm happy with that.

With the lastest update, circa end of June, it seems removal of whitelist not required as 5g still showing after update

Anyone else confirm ?

In my case, the update didn't revert any of the changes I made so everything was working as it should be.

Yes confirmed latest version Samsung LOCK 5G not working.

@tdodd @xUtsumi

Did Samsung or EE UK bring back the 5G whitelist for N9860? I just realised that I no longer have 5G and access code *#*#27663368378#*#* t9 access the service menu via Google dialer no longer works.

Has anyone else had this problem? I am on TGY 1st October 2021 security patch. Many thanks

I have not performed any speed testing, but I continue to see the 5G symbol on EE where I would expect to see it. I have not tinkered with the service menu settings for several months. I'm also on October TGY.

 

[silmarils]

Thanks @tdodd! I managed to connect with 5G in central London. Perhaps the 5G network has issues in my area.

 

[kradcliffe]

5g kills the battery so I just leave it totally disabled.

Hey, what firmware are you on ? and is your 5G working?

Hey is your 5G working with Andriod 12 ONE U.I 4.1 ? Please if you could let me know!

Yes. 5G working fine.

I'm on 4.1 (April security patch) TGY firmware installed on 17th April and still have 5G showing up on EE. I just tried a speed test with nPerf and that showed a 4G+ connection, even though the phone showed the 5G symbol. Using Speedtest app it does show a 5G connection, but speeds are rubbish where I live.
