Stock S7 (DBT, latest Nougat) won’t switch to 3G/LTE - Samsung Galaxy S7 Questions and Answers

As stated above, it stays at Edge forever. I tried 4G switcher, I tried flashing a MM Modem. Is this a known bug or hardware issue? Also tried network reset and a different SIM card. Any solution to this?

Go somewhere with a better data signal on that network?

I tried in multiple locations. It won’t switch to 3G or LatE, shows full bars on Edge.

It will stay on Edge if there is no 3G/4G signal
Check with another phone on the same network/carrier, if that gets only Edge too then your signal is bad in your area

It depends on where are you located. Nowadays, we've got 3G everywhere so it's strange.. did you contacted your carrier?

edge and HSPA+ connection auto-swtich problem w/ at&t

Hi there, IDK if this is just me or not. I live in Rochester NY which is covered by HSPA+. I purchased lumia800 unlocked on amazon and it works fine for both data and MSG without setting APN. The problem is whenever there is a bad reception and the data dropped to Edge, it won't reconnect back HSPA+ automatically when reception comes back. I have to go to cellular settings and switch to edge then switch back manually.....So, any suggestion?

This won't help you, but you're lucky having the switch in cellular settings. My Titan doesn't have one. It would help me at work where the HSPA+ signal is marginal at best. Edge would allow me to get and make phone calls without having to run outside the building.
Ugh, AT&T is *still* hiding that option on their branded phones? Idiots... It's nothing but a registry tweak to re-enable it, but nobody has figured out how to do registry modifications on the Titan yet.

Mobile network icons

I'm on NET10 via AT&T. I got my APN setup and I'm getting data and MMS. However, I wanted to know what the icons looked like for different networks. I haven't seen anything but "H" show up. On the N4 it would show H and H+ letting me know the difference. I was also in a supposed AT&T LTE coverage area, but it still showed "H". I think my APN is setup right. Other users have reported the same setting and getting LTE. IS the H to LTE switch take a while?

Hi I also enabled my Nexus 5, Though I am getting data, but I dont see any symbol at all, on top of my notification panel. I do see wifi symbol, when I connect to wi-fi but no cell phone mobile data symbol. Though mobile data is working for me.
Can you help?
Just got an LTE icon using T Mobile in Boston. Just the H for other areas. Haven't seen an H+ yet

I'm on AT&T via NET10. Have yet to see LTE yet. Even in areas that are supposedly covered. Probably will have to call NET10.

You won't see an icon while on wifi. Turn wifi off and see what happens. You should definitely see something indicating what type of network you are on.

Well, I know that, I have disabled the wifi, then only I tested the mobile data, but I didnt see any 3G/H+ symbol. Though network signal widget shows me the right data speed for the mobile data.

[Q] OnePlus One LTE BAND selection?

Is there a way to see and change the LTE BAND that my phone is on? Rogers support aws, 2600, 700. So I was wondering if I could manually change between them. The S5 has that option in the hidden menu, so I'm hoping I could do the same on this one.
Thanks.
The phone choose the band himself, if he don't find bands authorized by your phone company, he can't use them.

*#*#46363#*#* > Phone information > Set Preferred Network Type > 'LTE/GSM auto (PRL)'
That's as far as you can get in telling it what network to operate on. It won't let you select specific bands (at least not stock). Mine was set to 'TD-SCDMA, GSM and LTE' out of the box (international version) and since I don't plan to use my phone in China anytime soon, it didn't make sense for the phone to waste resources searching for a TD-SCDMA (China's homebrew 4G) signal. Haven't noticed much improvement to my LTE signal though, still the weakest radio I've seen in a 'flagship' in a while.
Thanks.
I am also on Rogers.
Does that mean when I am on the phone, it will revert to EDGE instead of 3g by using the LTE-edge setting?
I have major issues with reception on this phone.
LTE Works Fine but the 3G/H+ signal is awful, absolute disaster on this phone. It is extremely, extremely weak. And I lose coverage often and over 50% of the times my calls go straight to voicemail because Rogers uses 2g/3g for calling. The phone can't drop back to 2G or 3G in time to receive calls when on LTE
Rly frustrating. Have tried playing with all the settings.

I'm having issues with 3G H+ too. Dont know its CM issue or not coz I had nice H+ signals on Color OS...
Can't even use internet data. most of the time network drops after using internet for a bit.. Network just suddenly gone and after that it comes back with no internet. Internet comes back online after a while...
Really worried.. and annoyed coz can't seem to find any solve for this. Even Mahdi rom had this issue..

[Q] force to 3G only?

The 4G service at work between 8:30am to 5:30pm is literally unusable. I have 3 bars but as soon as everyone shows up, the data literally slows to a trickle. This wasn't always the case and I'd like to test the modem in 3G mode. My theory is that the 4G uplink is saturated but possibly not the 3G pipe. I don't believe the software provides this functionality to the user normally but since my device is rooted, is there a way to temporarily tell the modem to switch to 3G? I'm proficient in linux/unix and comfortable in a shell environment so a solution along those lines is fine for now.
Running android 4.4.2 w/ baseband i535OYUDNE1 (most recent OTA update from verizon), towelroot and supersu.

Thanks for the suggestion. I iterated through all of the options under "preferred network type" e.g. WDMA, CDMA, EVDO, GSM, etc. Changing the mode would remove the LTE symbol from the phone (and disable data) but I could never get the 3G symbol to show up. Is there another option I might be missing?
That's odd. I'm on 4.3TW and the CDMA (prl) option works.
Are you sure 3g data is present at your location.?

I can remember having 3g at one time here but I'll wait to answer that until I get home where I frequently get dropped to 3g.
But, I noticed something interesting in looking at the power metrics. As I said I have 3 signal strength bars and the 4G LTE symbol. But this app says I have -61 db(71%) LTE RSSI signal and 2db(44%) LTE SNR. Doing some google searches I found a verizon document that says that RSSI should be greater than -58db and SNR should be greater than 12.5db for LTE to work correctly on their network. So that would seem to indicate why my data performance is bad and not necessarily a saturated uplink to the tower. So, is the signal strength meter actual reporting CDMA (voice) RSSI?

I confirmed that the app won't push me to 3g at home either and I am frequently on 3g there.

problems with 4G OPO and Three UK

Ho peeps,
just a quick question. I just moved to 4G but I'm experiencing some funny issues.
On my OPO under "Mobile network settings", I changed Preferred network type from 3G to LTE (recommended) and I got 4G. But, occasionally, all of a sudden I can't make or receive phone calls anymore, even if there is good reception signal. If I change the setting back to 3G, then everything works again. So, I checked the frequencies just in case and the OPO, has we know, has LTE: Bands: 1/3/4/7/17/38/40 and Three UK (my provider) for 4G has 800 MHz (0.8 GHz) and 1800 MHz (1.8 GHz). Granted that I don't know much about frequencies, bands, MHz etc, could anybody confirm that the frequencies that the opo has are fine with the ones that Three has? If that's the case, why the opo occasionally plays up when LTE is selected?
cheers

Unless this has changed recently Three uses 2 bands for LTE(4G). One is Band 3 which the OPO supports which they use it big cities and towns and the other is Band 20 which they use in rural areas which the OPO does not support. I am guessing you are in a Band 20 area at the moment and that is why it is not working.

Well the 4g actually works, sorry maybe I wasn't clear, although it is patchy, but the issue is that often when the 4G is on, the phone doesn't allow incoming and outgoing calls even if there is full reception. When I switch off the 4g back to 3g the phone works again.

Here is something I just found on the subject.
Only two UK carriers offers LTE support with those frequencies: EE (supports band 3 & 7) and Three (supports band 3). Other carriers won't be able to support LTE coverage for the OnePlus One as they operate within band 20, which isn't supported by the phone.
Band 3 has limited usability in weaker signal areas, where it has difficulty penetrating built up areas and the interior of buildings, but it can carry more users. Band 7 (only supported by EE) offers wider coverage, as it can reach further, but cannot support as many users.
If you are an EE consumer, you wont experience any LTE problems. However, if you are a Three consumer (as I am), you may experience problems with LTE coverage, when you get outside of the major cities or in weaker signal areas within cities.
However, as Three offers extensive HSPDA+ coverage (or Advanced 3G (DC‑HSDPA) as they call it), you will still be able to get very fast data speeds (up to 42 Mbps). As Three offers 3G under the 2100MHz you will be able to get this speed with the OnePlus One in major cities and regular 3G in the rest of the UK.

thanks, that's useful, although I still wonder what causes that problem as I had it a few times now (can't make/receive calls when on LTE) as I assume the band won't have anything to do with it. I was hoping to find somebody else with that problem on Three, perhaps it is just a Three thing...
I'm on Three and I either get LTE (mainly London where I work) or H+. Either way I've never struggled, as far as I know, to receive phone calls or texts. Worried now though

I am having the same problem, have tried different serivce provider sims in my phone and they work fine, just the three sim, which I can't change as I am in a contract with them, and OPO customer service is horrendous! I have tried the sim in another phone and it works fine. I have tried to chnge to 3G only, but all the three sims are 4G enabled, so when I select the Three 3G network, the phone wont register on it, I can only register on the 4G network. I have tried installing CM11, CM12, Paranoid Android, OxygenOS and had no effect, tried safe mode, tried rooting the phone, and still no effect.
Really need a solution to this, but not finding any
To be honest this problem happens at random, at least for me, so it's difficult to find the exact cause. Touch wood I haven't had it for about a month now, but like I said, and from previous experience, it could happen anytime. Read what flumpster has found in the previous post. As for a solution, I'm not sure what to say, other than switch to 3G, wait for the 3g network to pick up and then switch back to LTE, (you might need to repeat this a couple of times if it doesn't work) that fixes it, at least temporarily.
