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

So if I run LTE discovery, it shows LTE band is 4, if I go into *#*#3282#*#* it shows bands 12,25,26,41 nothing else..... Also all 4 of these bands have a priority setting of 0....If I go into *#*#4636#*#* and go into the menu , select radio band...it shows USA Band, Band Mode 6, Band Mode 7 and Band mode 15 which is weird no indication of band 4 anywhere..... I read that Telus's fastest LTE is on Band 7 but I have no clue how to get there.... I am downtown Calgary so there should be coverage... any suggestions?
Hi,
I own sm-t715y, samsung website mention the availability of tdd lte band 40, i want to use a provider which is data only, it doesn't have any voice capability (called bolt). And a cdma provider which uses tdd lte band 40 as well (called smartfren).
Most of the tutorial on other devices which has tdd lte band 40 support has these steps:
1. Force lte only
2. Turn radio off and on
3. Set apn
I can't set force lte only on this tablet yet, tried *#0011# and *#2263# but it cant, the 2nd one cannot pop at all, please advice
When you say other device, this isn't Samsung is it.
I also have a S2 with band LTE 40, why don't you just buy a data only sim card, that is what I have 10GB data 1 year time limit.
Yes, the other device is oneplus one, alcatel one touch flash.
I tried experimenting with smartfren but no success at all, have not tried with the data only bolt, the cs said it cant but i doubt its true.
That is why, I had many Samsung, and non of them has lte only.
different phone/tablet has different features.
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.

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.
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:
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 using M2003J15SI Model,Using Jio,MIUI 12

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
