Manually select an available Band? - ASUS ROG Phone II Questions & Answers

I saw with the Samsung S20 and S10 phones there is a non-root method to selecting your preferred available band on LTE, etc.
Is there a way to do that with the Rog2?
I have a situation where after a reboot or airplane mode off and 4G comes back on, my Rog2 will select the faster LTE Band 3 in my area, but then after a few minutes, drops to the slower LTE Band 1 and then never goes back to Band 3. The speed difference is considerable - basically double speed on Band 3..
Anyways, I'm guessing there isnt a way to do it, but keen to know if anyone has any tricks :good:

Forcefully Change LTE Band (Verizon)

Is there anyway to force LTE band change between bands 13 and 4? At home, I have one bar on band 4, but get 60 dl, and 30 up. However, on band 13 I'll get full bars and get 30 dl, 15 up. I don't use my data at home as I am always on wifi, so this cell standby battery drain is murder. If I reset my data connection it will connect to band 13 initially, but it will then change to band 4. Switching my carrier is not an option as T-Mobile, Sprint, and AT&T get equally crap reception and I'm still under contract with Verizon which ends in October. Maybe then I might think about switching to project fi.
I've seen other threads on disabling certain bands, but those bands are only used by T-Mobile and Sprint, so they are of no use to me. Any ideas?
There is a thread about 4G/LTE.

Further search the play store for 4g switching apps.

I've seen that thread but it doesn't say anything about removing or blocking certain bands. As for the 4g switcher apps they only have he ability to change LTE modes via CDMA or GSM
The last idea, in case you use a Nexus 6.
There is thread with flashable radio's.
Maybe you can find an older radio that doesn't have the bands you don't want.

Yeah, i tried flashing the oldest radio listed and it's still a no go, band 4 still seems to be enabled. :/

No more ideas; think it is not possible to disable band 4, without hacking/patching the radio image.

For now I have my connection as 2g whenever I'm on wifi so that should fix the cell standby for now.

I have the same because here in the Netherlands we have the so called 4G. But when I am home (inside) there is bad connection. Phone calls are disconnected frequently.
With 2G very good reception at home.
On the road I switch to 4G when I need internet.
I use an app to quickly switch 2G-4G.
It's a rather old app of CurveFish and is in the play store - 2G 3G -
I have exact same problem but problem of speed.
There are 3 lte bands 850mhz,1800mhz and 2300 mhz.
2300 mhz has highest speed which i want my redmi note 3 to run on only but in my home it only switches between 850 mhz and 1800 mhz.
Searched a lot but not able to find any guide which allows to lock the frequency to 2300 mhz band only. The signal bar is also 3-4 on 2300 mhz still it connects to 850 and 1800 mhz most of the time unless i am in open area outside house then it switches to 2300mhz band.
Use QXDM

Hi - not sure if this is still a topic of interest, but you can use QXDM software to achieve this - you just need to change NV line 6828 to be "4096" decimal value. On the Nexus 6, this is a fairly easy process as you just need to boot to bootloader and select "BP Tools" as your boot-up option and then the phone will be in diagnostic mode to connect to a PC. There's info out there on XDA with more detail, but as long as you can successfully install the Motorola/Qualcomm drivers you can fairly easily restrict LTE bands to whatever combination you'd like.
Be aware - some say this is a risky operation but I've not found that to be the case. But there is a chance of messing up your device if you're not careful.
Take a look at the "NV Calculator" app in the Play Store for additional info on determining decimal values for the LTE bands (you might want to keep band 2, for instance, as Verizon uses that sometimes as well).
Here's more info on this on XDA:

T-Mobile LTE band 12 in the SF Bay Area

I have a Verizon S8 that I flashed with the XAC firmware and so I'm at XAA/VZW/VZW after enabling all bands. However, even though the entire bay area should be blanketed under band 12, I have not once connected to band 12. I'm always on band 4. Has anyone with a original Tmo S8 ever connected to band 12 in the SF bay area? You can check using LTE Discovery or SignalCheck apps from the Play store. The whole reason for me to go through the trouble of flashing the non-VZW firmware was to ensure I would be able to access band 12 but doesn't seem like that worked.
I'm sitting at home on my T-Mo S8 in the SF Bay Area and I'm on Band 4. I'll check at work tomorrow morning and let you know.
If you don't have connectivity issues, it shouldn't go to band 12. As band 12 is a lower frequency and cannot carry as much bandwidth. From what I've researched previously, the phone will only take a band 12 signal if there are no other bands with a stable signal in the area as tmobile got it for the sole purpose of distance and wall penetration achieved at 700mhz to say they have a larger LTE coverage map.
. Also this from experience as my house only gets band 2 outside and when I come inside it switches to band 12. And with the lte booster connected, it uses the outside band 2.
Unless you are saying that your phone goes to no service instead of to band 12, then i have no answer
Dail *#0011# in your phone to see if band 12 is being aggregated with band 4.
If you want to see if band 12 works you could dial *#2263# and select only band 12 to work.

after we select band 12 only or any other band of our choices, how do u apply the new setting ? i click on back and entered 0011 and noticed im still on band 4 ? then i went back to 2263 and noticed all the lte band are still selected with *

You have to select "Apply band configuration" after you selected the ones you want or they wont take effect.

got cha. gotta hit back to previous screen where i previous selected lte band, but press option 7 to apply setting. lol. still new at this but it works. although band 12 is just as slow as band 4 at home. i get faster speed with band 2, however, lte discover still shows band 4 even though im actually on band 2.
tks again

No prob!
I used LTE discovery before and it always told me i was on band 4 when it wasn't in my area, only 2/12.

never got to try the service modes since i been using verizon brand phones on tmobile , lol. it makes so much sense to use tmobile brand samsung phone on tmobile network.
anyway now i can wait patiently on the root. no need to get network signal guru now to change lte bands since that app requires root
Thanks all. I bought the Verizon version cuz it's unlocked and it was the cheapest at Best buy. Plus it would be a hand me down for my bro who's on Verizon service when I upgrade lol I always thought band 12 was the godsend for Tmo. I did not know it was just a fall back band. I did notice today at work I was occasionally connected to band 12 but would almost immediately reconnect to 4 whenever I checked. Either signalcheck app was wrong or it really only uses 12 for a back up if nothing else is available.

Blank service mode

Hello,
I use the Three network in the UK with an unlimited data plan and they provide a service called 4G Super-Voice also know as VoLTE.
To get this working I had to flash my Note 9 with the 3 firmware which is annoying because of the boot screens but its worth it for VoLTE.
Anyway, I can only access 4G Super-Voice if I put my phone in aeroplane mode and then off aeroplane mode. I then can see using *#0011# that I am using band 20 which is used for 4G Super-Voice.
With this, I can access VoLTE, better signal and faster 4G speeds. But after 30seconds it goes back to Band 3 and I no longer have access to VoLTE and the faster speeds Band 20 offers.
I have had a look online and a few people have fixed this on other devices by only letting the phone access Band 20 and disable the rest. On my Note 9 when I try entering Service mode using *#2683662# I'm left with a blank screen with no options to select. Not sure if 3 have locked this on there firmware or if I'm accessing the menu wrong. Any Help is much appreciated. Thank You

Yes, you can lock out certain bands while allowing others, but the *#2683662# code has been deprecated in the latest models/firmwares.
Enter this diag code *#2263# or *#2766338378#, tap LTE Bands Preferences, one by one deselect all the bands you don't want (especially band 3), tap on Go Home or Go Back/Previous, and finally tap on Apply Band Configuration. If you did everything correctly your phone should no longer pick up the unwanted bands.
Here's some more information about this issue.

Signal Strength

Just a question. I had the S8+ S9+ and the Note 9 and seems like all the Samsung phones have terrible capabilities of keeping a signal in bad areas. We own property use mainly for long range shooting in FL and it's hit or miss getting a signal. Wonder if the S10 is any better? I don't think so but wanted to ask.
We switch to the Moto's Hers Z3 MIne Z4... and Motorola is the best same area up at property no issues at all. So proof that sammy radios suck.
FYI we are on Verizon.
:cyclops:
I have 3 towers, all 2 miles each away from my house, and I sit on 1 bar, if I'm lucky....it sucks.also on Verizon. Have an s10.
Just want to share how I solved this or similar problem in Malaysia. I find S10 sucks at band switching, I can literally see my 4G bars jumping from 1 bar to 4 bars then 1 bar and so ford , you get what i mean. This phenomenon is more significant when the phone is hold landscape or some of us called it "the death grip". Basically what the bars jumping means is the S10 is trying to switch to a "what it thinks more reliable band".
well, here come the good after all the bads, you can fix the problem by fixing the band, preventing it from keep switching like crazy. Luckily for me, my carrier provider use band 3,7,8 for 4G. i believe band 3 is 1800 MHz, 7 is 2500 MHz, 8 is 900 MHz. if you know physics, lower frequency can penetrate walls better, so I fixed my s10 to band 8. Oh ya, 900 MHz may benefits gaming latency as well, although lower down link.
Now my S10 have constant 4 bars in my living area. But beware, not all places have the same strength for all band, you need to find out your self for your carrier. This is how you can do this trick:
Go to Phone App -> Dial *#2263# -> Stack 1/2 (number of SIM) -> Band Selection -> LTE -> Band of your choice.
One nice thing about S10 is you can fix 4G band without disabling 2G/3G, which is super nice when you go to non-4G area. You can always revert to default by selecting Band Selection -> Automatic -> Preferred bands
Hope this helps.

TDD LTE bands missing

Hey guys,
xda still going strong. nice to see.
need some help though.
i bought a note 8(yes in 2020) for some reason(side device) and i got stuck with a problem right away.
i noticed that TDD LTE bands(band 34,38,39,40,41) are all missing from my device.
i am having an exynos varient (n950f)
i was monitoring my network from past 2 days and 3ca was working fine. i was connected to 3,5 and band 40 all together.
i wanted better reception so went in network selection mode and selected band 5 preffered. i dialed *#0011# to check my ca status and i was still transmitting on all 3 bands with speeds well over 100mbps.
after some time my speeds died and i no longer see band 40 in *#0011# menu and i have tried restarting device and what not but still cant connect to band 40.
i am pretty sure TDD LTE bands including band 40 was missing from band selection menu earlier too but things were just fine. not i am stuck with a expensive device that fails badly.
please help.
on some inspection i observed that my phones is continously doing 2ca even when using no major data on band 3 and 5.
basic is stuck on band 3 and s1 on band 5. me changing to whatever setting in band selection in hiddennetworksetting dont affect it.
tried selecting bands that my operator dont even support. not in preffered mode but as the only hard selection. makes no diffrence. network signals shuts for a second and i am back on band 3 and 5 combo
