So I Tried To Disable Band 40 And Only Enabling Band 3 or 5 But It Didn't work Band 40 Keeps Re-enabling itself,it affects me cause in my area Band 40 is slow Band 3 is Faster Band 5 is the Fastest(Tested with my POCO F1). I also Rooted the Phone and then tried using some apps like network signal guru etc. but they dont work cause they only Support Qualcomm. Is There Anyone who can help me with this?

I am also having the same situation with my Redmi Note 9 (Global Version). It keeps rechecking the band 40. However, I think that it just keeps rechecking by display only, when in fact it is really turned off. For example, I am currently in band 40, then I unchecked band 40, leaving only band 3 checked. When I check the band selection again, band 40 was checked. But when I check the band in the "Network Monitor Lite" app, it is connected to band 3. So I think, it only displays (checks) the band 40 when in fact it is really turned off. Thanks

Over the past month it appears that Band 26 LTE has been activated in my area, which is causing my previously stable LTE (previously Band 25 only) to drop to cycle between 3G and Band 26 LTE about twice a minute.
I can access the ##DATA# and disable Band 26 which allows it to remain on a stable Band 25 LTE connection.
However, I noticed today that if I access *#*#4636#*#*, go to Phone Information, then press the three dots on the top right and then "Select radio band", I can then press on USA BAND, Cellular (800-Mhz Band), PCS (1900-MHz Band) and then Secondary 800-Mhz Band. Once I do that and exit those options, my phone then keeps a LTE connection...even a better connection than normal and it even stays on Band 26.
If I restart the phone, the symptoms come back unless I go back to that 4636 menu and perform those steps. Any ideas?
The *#*#4636#*#* option you're messing with is for phone access (3g) so you're effectively disabling 3g to get connection also, try disabling band 41 instead, sprint reps were saying it caused most of our problems when spark was breaking phones
Also try calling sprint and make it so you get 3rd level tech support (which will take you out of india and back to the states) they tend to know their job better

I did just discover that disabling Band 41 (in this area I do not have Band 41, just 25 & 26) hashas allowed my phone to cycle between band 26 and 25 without issue. I then, with the recent update to the M8 you can also change the band priority, changed priority to 26 then 25 (was 25 to 26). That seems to have helped it remain at even a band 25 connection longer when the signal is weaker.
Thank you for the reply. Do you know what is up with Band 41?

If that worked and you are able to set priorities then your towers are telling your phone that there IS band 41... my area doesnt have band 41 as it still has wimax enabled and the band priority option is unusable to me, it just says "unable to set priority with only 2 bands enabled", even though I havent disabled any bands it knows there is no 41 here...
This was a huge deal before the 1.10.xxx update are you still on 1.8.xxx? If so that might be the issue, if not call sprint, have them fix it

I updated to the version released this week (3.30.651.2) , which also gave me the option to set band priority.
It seems that perhaps a recent PRL update turned on Band 41, thus the issue started. The recent PRL update again turned Band 41 on, which I disabled to restore LTE stability.
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.

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:

Good luck!
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.
Hi, is it possible for me to change (and stay that way) the LTE bands on my phone without root? My network seems very slow on band 5 LTE and I'm looking to change it to band 38 or 40 instead. Thanks
Base on my experience, it's impossible not to root your phone and change system files.
I already have both bands on, it's just the matter of preferring one band over the other. I tried manually to search networks in the advance tab and managed to connect manually for a minute to band 40 network before it automatically changes back to band 5 ( even i selected thr the network manually)
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
