I would like to get information on LTE carrier aggregation and neighboring cells,
but I have tried various applications and cannot get it.
Is it possible for the Pixel6 to get the Neighboring Cell information using the Android API?
What you see is what you get. Cell info is minimal on this phone. 5G anchors don't reliably show up and there's no way to see aggregated bands. NSA band indicator does show up though.

Security/privacy concern.
How do I verify my non-LTE variant of the Nexus 7 Asus K008(ME571K) is NOT pinging cell towers with device identifiers?
I'm wondering because the LTE variant of the Nexus 7 Asus K009(ME571KL) does have LTE / WCDMA / GSM support. Maybe my K008 still has a 2G antenna and it's pinging local cell towers? I'd like to know for sure. Thanks.

The LTE model has extra hardware: RF ICs, antennas, SIM slot, etc. Compare the attached pictures of the LTE PCB to WiFi-only version here, they are completely different and no cell tower pings are possible. I'd be more concerned with Gapps, Facebook, Uber... apps, you've no privacy with them. Install a custom ROM without Gapps or try LineageOS for microG.

Thx for the info, but I can't tell the significant differences myself from the images.
However, I did find these pages:
(non-LTE)
https://wikidevi.com/wiki/Google_Nexus_7_(Gen_2,_Wi-Fi_only,_16_GB)
(LTE)
https://wikidevi.com/wiki/Google_Nexus_7_(Gen_2,_4G,_32_GB)
On top of your assurances, I'm also comforted that the LTE version indicates "WWAN RF FEM is a WTR1605L (multi-band 4G LTE)" while the non-LTE does not have a WWAN.
But the non-LTE version apparently has GPS, indicated in the "additional specifications" section near the bottom.
Should I be concerned about GPS? Does it ping passively or otherwise? Does it transmit any device identifiers or location?
Recently got Verizon Note 10+5G unlocked and I use AT&T on this. Signal is so pathetic on this and I am not getting good speeds on this. In the mobile networks, there is an option like Global or GSM/LTE or CDMA/LTE. Which one do I have to choose?
Any flashing that can help this to convert to an AT&T phone?
Thanks
Did you change the CSC code?
I am using the same phone on T-Mobile and I can tell you that the signal strength is far superior than my previous unlocked Galaxy S10 Plus Snapdragon. I have been using Global mode. If you're talking about the 5G band, this model supports 28GHz and 39GHz spectrum bands. As AT&T holds 40% of 39GHz bands, you should get signal in many cities. However the signal from these mmWave antennas don't go very far, you need to be very close to the 5G antenna. I have been lucky to try 5G on TMobile with 28GHz on this phone, performs well when you are near the antenna (TMobile holds only 12% of 28GHz spectrum and hence 5G on this phone limited to only few cities).
You can't flash cross carrier or unlocked firmware on this model, however you can disable many Verizon apps to make the phone look clean.
PS: The only reason I could think of for bad signal is if you changed the CSC code to GCF. I had changed once and I know the consequences including the signal drop at high rate. Phone is not meant to use with GCF CSC.

No I didn't change the code.
I have a PM edition that has been cross flashed to a ULM. Someone pointed out that the ULM version doesn't officially have certain US bands like 12, which are very important for T-mobile/AT&T here. But the original PM version does have those.
I went into the service menu (*#546368#*710#) and found the bands listed under the field test mode and went and disabled everything other than B12. At first there was no service, but after a quick toggle of airplane mode, I'm connected to Band 12 (according to signal spy at least). I even did a speed test to make sure it was sending / receiving data. I was previously connected to Band 2 before doing this.
I'm not sure what this proves- is B12 only available because my hardware is the PM version? Or are the bands controlled by software? I have to admit, the service menu seems to offer all the possible bands this SoC is capable of, including B71 . That's interesting because I thought B71 is only on the T-mobile version and not available on the ULM or PM versions. Does fiddling with the service menu essentially let you enable whatever band you want on any edition of this handset?
I have a real ULM and connect to LTE 12 without issue. IIRC, your PM crossflashed to ULM will work on all T-Mobile LTE bands except 71. If you feel like experimenting, there were rumors that AWM firmware may enable band 71 although I don't know recall anyone specifically testing it.

I'm thoroughly confused now, I swapped to another "ULM" (also crossflashed from Sprint- the first had a physical defect that I returned and swapped for another), and didn't do anything to the service menu and STILL connected to the same bands according to software reporting. Bands that according to online resources, the ULM isn't supposed to support. Yet it does, and you say your real ULM does too. So obviously the spec sheets online are wrong and I have no idea what bands any of these handsets actually support or if doing anything in the service menu makes any difference at all.
Someone said another edition of this handset (european maybe?) had his menu showing a different set of bands available to select than mine, so I wonder if this is controlled via the firmware or the hardware (NVRAM values or whatever?). The service menu appears to just serve as a way to isolate bands available to test if certain ones work where you are. And on my PM turned ULM, band 71 is listed. I don't have 71 around me so I have no idea if this is real or not.
Wish there was more (accurate) information about there about how this works.
I'm on T-Mobile and usually connect to LTE 2, 12 or 66. Of those I'd say most of time 66. I've never seen a connection to 71, which I always figured meant that its not supported by the phone. If you are interested in trying to get 71, flash AWM and see what happens.
So it follows the firmware or it follows the hardware (nvram values)?
ALL g7's other than the g7+ are capable of the same bands. They are software enabled or disabled or even hidden.
If you can access ##data# from dialer and input the msl code to get to band priority then you can connect whichever you want.
If not the secret menu is needed to access the ones you need.
If the firmware did not include the band in secret menu then it has been disabled. At that point you need to access via a nvdata application like cdma workshop to enable them forcefully, but it will clear out after each restart since cdma workshops adds the band temporarily.
Well why do the bands on ulm stop at 40

The ULM version definitely does have Band 12.
How do I know? I followed this guide: https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/#LG_devices
I extracted the qmdl log and followed the steps to extract the actual supported bands as well as carrier aggregation combos right from the actual modem logs (which are 100% accurate, since LTE devices need to report this to the network every time they connect to it)
LG G7 ThinQ (US) (G710ULM) | 4G/5G Bands & Combos
4G & 5G Bands, Carrier Aggregation and Dual Connectivity Combinations for LG G7 ThinQ (US) (G710ULM)
cacombos.com
Here it is for the LG G7 ULM. Not only does it support Band 12, it also gets Band 17 and a wide variety of CA combos in that band.
Hi all,
I'm wondering whether it is possible in some way to unlock additional NR bands on the S20. As far as I understand the Snapdragon 865 chipset, it comes as a fully-fledged 5G mobile platform which can be used in all countries and which supports all possible NR frequencies/bands.
So, it seems to me, that Samsung just locks off the majority of bands in the different models (for example, I got the G9810 and like to use it overall in Europe. However, Samsung only delivers the bands N1 and N78 but not e.g. N28).
Would be great if anybody could give me a hint about this.
Best

I think there is no way to add more bands because these are defined to hardware. But i'm very interested about your model 4G Carrier Aggregation Combinations. These can get from log file: https://mt-tech.fi/en/how-to-get-4g...ons-from-your-android-phone/#Qualcomm_devices . Could you please share to me this BandInfo file? You can send this to https://cacombos.com/contribute
check out the Samsung Band Selection app on the Play Store. Supposedly, it can unlock hidden bands.
I looked at it but I'm unsure which bands are available to Sprint/ T Mobile in the St. Louis area. I set to Automatic. Playing it safe I guess .
Also when I switch to 5G it doen't show any bands. The S20 + is capable of more 5G bands I hear

Only can disable/enable bands what hardware support. If it doesn't you can't just randomly unlock bands.

What model Samsung S20+ you have? From modem logs you could export some data what your phone support: https://mt-tech.fi/en/how-to-get-4g...ions-from-your-android-phone/#Samsung_Devices
I have the Samsung Factory Unlocked version of the S20+ (model SG-M986U1).* This means the phone is not carrier-specific, it works on all carriers (CDMA, GSM) and supports both millimeter wave (Verizon 5G Ultra Wide UW) AND lower frequency band 5G (usually called Sub 6).* The 5G UW super fast network is typically only available in highly populated areas (cities) because it that frequency signal doesn't travel very far and is easily blocked by buildings.* However you will notce the Verizon 5G coverage map shows 5G as being pretty widespread across the country.* Most of that is their Sub 6 5G Network which was launched in mid October 2020.* The 5G Sub 6 network, to my understanding, is using some of the same frequency bands as 4G so essentially it's really an amped up 4G signal using what is called Dynamic Signal Sharing (DSS)*(A lot of people don't understand all this.)*
I'm curious if there's anyone on the forums with a factory unlocked version of the S20 (typically the model number I think has a U at the end instead of VZW) can confirm if their phone shows a 5G icon when you are in sub 6 5G or does it show "LTE+"* I read somewhere the unlocked phones show LTE+ because technically that is what Sub 6 band 5G using DSS really is and 5G in that case is more of a marketing term.* Because different carriers use different terms for different networks, the factory unlocked phones can connect to all the different 5G networks but they can't accomodate all the different marketing terms.* I'd also be curious if when connected to the millimeter wave 5G in the cities if these factory unlocked phones show the "UW" designation which is bascially a Verizon marketing term, or if the phone just shows "5G".
There was also an article that talked about these phones needing a software update to use 5G and supposedly the updates were pushed out right after Verizon announced their Sub 6 5G network launch in mid October. But the author wasn't sure if the Factory Unlocked non-carrier specific models would receive the necessary update. Considering Verizon and Samsung just signed a 6.5 Billion Dollar agreement for SAMSUNG to further build out their 5G network, I would be very surprised if it were the case the factory unlocked models didn't get the update.
My S20+ model SG-M986U1 is showing Service Provider SW Ver. SAOMC_SM-G986U1_OYN-VZQ_QQ_0027 wondering if that's the 5G compatible version?
The other thing is a lot of people just swap SIM cards when they get a new phone. With 5G in most cases, if your SIM card was issued may months ago, you need to go into the carrier store and have them give you a new 5G compatible SIM card. I honestly can't remember if my phone was showing LTE or LTE+ before and after SIM card change. I tested the bandwidth after the change and in a strong signal area got 60mbit download but I didn't have a pre-SIM swap test in that area to compare to unfortunately.
Well I feel like I'm going in circles but now found a Reddit thread that confirms what I originally suspected.
The Factory Unlocked (model ending in U1) S20 phones apparently have not got the update from Samsung yet to allow sub 6 5G connection. But there is a hack in that you can change the carrier network code to ATT even though you are on Verizon and it enabled the N5 band which is what Verizon uses for their "Nationwide 5G" To do this you dial *#272*your IMEI number# Then select ATT and Install and change network code only. Phone will reboot and now you will see 5G UW symbol.
I tried the CSC change on my factory unlocked S20+. I ran three successive bandwidth tests on bandwidthplace.com before and after the change so 3 times on VZW and 3 times on ATT. As others have alluded to the LTE DSS Sub 6 Flavor of Verizon 5G is on average about the same speed as 4G LTE+. So I just turned it back to VZW and will wait for the update from Samsung. I'm surprised a month and a half later it still hasn't got the update to allow N5 band on Verizon.
I'm also wondering is the S20 always show 5G UW when connected to any 5G including sub 6 5G and not actual millimeter wave ultra wide 5G? Or is that just a side effect of "spoofing" the ATT carrier code when actually on a Verizon network IMEI?
Hello Jazee, this is my first response to anyone on xda, and I know that by now you probably have your answer I notice this is an old post. I have an unlocked Samsung s20 5g. And depending on where I am, it says 4g let, and when I'm closer to the city, or hold my leg right(I live in the country), my phone shows 5g. It's shown lte+ before. I think it depends on your carrier. Some I've noticed share 4 and 5g lte simultaneously depending on the current speed. As you mentioned earlier, 5g signal doesn't put up a big fight when it sees a tree or building. Anyways, that's my 2 bits worth, hope this helped. BTW, lte+, when I get that, it is pitiful. Nothing like either 4g lte or 5g lte.
