[Q] why would this happen? - Nexus S Q&A, Help & Troubleshooting

yesterday I was at my friend's house where I would get really crappy reception. I decided that I would turn off the data connection and make the phone use only 2g networks to save on some battery life. when I re-enabled 3g networks, my phone would only get edge service. this happened for the rest of night, and even though I figured that it might be a carrier issue, I decided to do some searching on the internet. I tried doing the *#*#4636#*#* thing and turning on only gsm networks and resetting the radio, but nothing seemed to help. finally I found a thread that talked about being on the wrong radio band (I think it's called), so I did the *#*#4636#*#* thing again and put it on the usa band. this actually fixed my problem and i've been getting 3g ever since.
why would enabling only 2g networks or turning off the data connection put the phone on the wrong band? i've found that it happens whenever I enable only 2g networks in the settings menu. anyone know why?

I can't speak for your case, but I know for T-Mobile in America when you switch from edge (2g) to 3g the phone has to actually turn off the data, then turn it back on with the frequencies of the other connection.

that might explain why it went to a different band in the first place, but why would it get stuck on that band even after 3g was turned back on? I even did a hard reset and turned data off and on during the few hours that I was stuck on edge but it did nothing. could it be a carrier problem? I would imagine that the only fix would be to bring it into the carrier's store or call them to get the phone put back on the correct band

[Q] Phone freezing when talking in WCDMA/GSM mode

I have a Samsung Galaxy S 4G from T-Mobile USA.
I don't have this problem when I set my phone to WCDMA Only but when I set my phone to WCDMA/GSM Auto mode, the phone would freeze while I'm talking on the phone. It seems to happen whenever the phone needs to switch from WCDMA to GSM (or vice versa?). It's just my guess though.. When I drive down I-280, my phone does switch between GSM/EDGE and WCDMA quite a few times (bad WCDMA coverage), and I think the freezing happens at points where the phone needs to switch to a different mode.
I use T-Mobile in San Francisco Bay Area, and I really don't like to leave my phone at WCDMA Only mode because the coverage is less than adequate. GSM Only would make data too slow.
Is there a way for me to pinpoint the problem? (any debugging tools?) The phone freezes and nothing happens. If I wait a while, it usually comes back up but until then the call drops and none of the buttons on the phone works. Very frustrating. I was having a conversation on bluetooth driving down the highway and I had to call back 3 times in 20 minutes.
Lastly, I use LauncherPro Plus but didn't make any changes (no rooting or changing ROM).
Thanks!

Network issue

Hi everyone
I have an issue, when I'm on my office the network signal isn't strong so when my One S go to "NO NETWORK" after it don't go back to network.
When the situation is this I can't go to airplane mode, change operator (from settings), the only thing that work is shut down and restart (no fastboot).
Anyone else have this problem?
Maybe is a software bug?
I have the Paul recovery and su
EDIT: More info
That don't happen every time that the phone go to "no network".
I think that happen when it a weak signals and are under 2G network.
there are users with similar issues, I only use 2G networks. If i want to do a bit of browsing i will manually change to auto mode, but other than that i always leave it at 2G..
hopefully there will be a radio upgrade soon that should fix this problem...
I'm suffering from the same behavior!
I'm still with the original ROM with no ROOT so I contacted HTC about it yesterday.
I got today their reply today:
"On your phone, kindly go to settings > mobile network > Network mode, kindly change the network mode and check how the signal will respond to each of them.
-Kindly try a different SIM card, to check whether the issue is with the SIM card or the phone itself.
- Soft reset for the device by pressing the power button for 10 seconds.( Note that soft reset erases any unsaved data.)
- Safe mode(which disables any 3rd party application which might be causing conflicts for your device.) for the device by Switching power on , then press and hold volume down when the quietly brilliant logo appears on your screen, you should see 'safe mode' text written on the bottom left of your home screen.
- Factory data reset, kindly backup your data before proceeding with this step please as you will
lose every data on the phone's memory.
Please go to Settings > storage > Factory data reset > Reset phone."
I haven't done anything yet and I didn't notice the 2G issue you mentioned.
I also haven't got this issue for the last 48 hours but did encountered it twice (!!!) on Sunday while driving across the country.
I'll try having the Network on 3G only and see if that matters although the area I leave in is not with good 3G reception.
GSM is 2G
WCDMA is 3G
i use GSM only unless im using the net
I'm aware to the 2G-3G difference
I'm on WCDMA preferred so my phone tries to be on 3G.
My phone also suffers from the 3G<->H data connection jumps while the desire wasn't having any with the same provider (different SIM of course).
sorry, My bad !!
i understand what your saying now
I cant confirm much as my provider doesnt have 3g signals in my area
If i try to use 3g at my home, I have 0 bars thats why i always use 2g
I switched to 3G only (since I have most of the time 3G and surly wants it for the data rate).
I know I have on my way to work and back places with 2G only but I'll give it a try for the coming days and reply.
BTW, just few minutes ago, while having 3G active for sure (before the 3G only switch when it was still on 3G preferred) I couldn't make any phone call although I had 4-5 bars and data connection was running.
Two days ago I tried to change my sim.
Before I had a cutted microsim, now an original microsim and the issue is still present.
Yesterday I had this problem only in afternoon, not in morning and only where the switch from no network -> 2G -> 3G is very very frequent.
In all other times out from office I never had this issue.
I also changed SIM with no help, stayed in 3G network only with no help and observed that when such a network crash happened, GPS reception is also disconnected!
I had no coverage situations with the 3G only mode which recovered, but what we are facing is a network "crash".
Our situation was escalated to technical support of HTC after I wrote them all the data and they tried to solve it over the emails w/o success.
Same problem for me. I tried only 2G, 2G/3G, only 3G, but no way..same problem..i hope an update can solve this..
I just bought my new One S from T-Mobile yesterday and everything appeared to be okay but now I can barely get it to hold a signal. Forget throwing it on GSM only because it will have signal for a whole few seconds before dropping it. I also am having Wi-Fi issues as well. It just intermittently drops the connection there as well... Not a great start!
whether im imagining this or not im not sure, But for me it seems like, When the Network signal increases, the WiFi signal drops, And when the WiFi signal Increases, the Network signal drops...
ive been noticing this for over a week now, So it cant just be coincidence..
I dont think my (or our) handset is faulty, I just think theres a pretty big bug in the ROM, and no matter if you switch ROMs they all use the same base at the moment..
This phone has great potential. But HTC need to be listening to us and release some updates. !!

I noticed the same exact issue last night. My phone will go to full signal before dropping whichever connection. I'm just glad this phone can handle staying on 4G without draining the battery like crazy although I can only imagine how much further it'd go with 2G.

Exactly the same here. But I had a different WIFI issue - WIFI won't drop but stay connected - even if I am far away off the AP.

that one is also a known bug.
On top of that, WiFi will sometimes stuck at "error" status with no ability to turn it on...
All probably related to the same network chip driver or "Radio"...
I have same network reception problem. When I am in a poor reception area it loose reception all of a sudden and takes a while before getting the signal back. I often toggle flight mode to force network detection. I also think the reception bars don't reflect reality; sometimes it seems I have good 3G reception but cannot surf the web. I fear it is a critical bug. The phone seems unable to handle correctly signal fluctuations and protocol changes (GSM, 3G, HSDPA).
I'm colletting more data about this problem.
First of all I don't have any wifi issue, or maybe I don't see this.
I have a modem with N standard and one with G standard and nothing of this have issue.
About the network issue in this days I never have, only when I'm in office and the signal suck a lot.
Q: Anyone that have Tmobile/mod rom with 1.70 RUU have this issue?

I don't have wifi issue at work with a powerful 802.11n network AP but experienced occasional fake/unstable/disconnect wifi at home with a poor AP which operates on no-one-knows-but-definitely-not-N network. I don't really bother too much cos I can always turn wifi off and on to reconnect.
In terms of 3G/H signal switching problem, yes, a bit annoy especially when playing online game on 3G but accessing internet is fine just need to sometimes wait a bit longer.
I am on international unbranded version in UK.
I've the same problem in France about 3G/2G and wifi on international unbranded version.

[Q] gsm loss no call no data

Please help
My S2 plus loses signal, data and no able to call and eferything. After restart ok for couple hours and then again. What can I do?please respond.
Reset to your phone..if that doesn't do the job ,just flash new firmware. If still doesn't work,send back to service center
I would recommend you send to service center.
On second thought,better check whats wrong with ur sim card.i think the problem start from there.pull it out and clean the contact point a bit,or switch other sim
Yeah, it can be the fw. After I had my motherboard replaced it wasn't picking up any signal at all. got at a friends place on the 9th floor to see that it caught 1 operator out of the main ones. Thought they didn't plug the antenna or something, send it back in only to receive it reflashed and nothing else.(the repair course stated something like: no damage fount, reseted settings). Guessing they just flashed England's FW and the bands didn't work well.
I had something like this when i had gsm/wcdma connection type (dunno how to it right in english). Where i live there is poor 3g connection and sometimes when phone loses 3g connection and should switch to 2g it does not and simply says no signal. I switched to gsm only for a while (should get better area coverage later) and i don't lose my signal anymore. If it is crucial to have 3g you can switch on and off airplane mode and you signal will be back, at least it was for me.

[Q] Sprint - can't connect to 3G? LTE only.

I have the opposite of the LTE dropping problem I see most people have. I can't get 3G, but my LTE works fine (well, once it spazzed out after a PRL update and would only do 0.5mbs on LTE). At work, where I know I can't get LTE, but could get 3G with my Note 2 (and we even have a repeater), I can't get data. If I go to the window where I can barely get LTE and reset my antenna, it'll get LTE, and when I walk away it'll flash 3G for a second and go out. I still get several bars and can talk and text fine. Everyone else with 3G is fine. After thinking about it I realized that in the month I've had the phone I've NEVER been able to connect to 3G in places where I used to be able to. It's LTE or nothing. I'd be more than happy with 3G if the alternative is to read a book. Could this be a SIM card issue? Hardware? Firmware? It's annoying the hell out of me, I work 10 hour shifts at night, I need my data.
Just a follow up, I downloaded a network signal info app and it shows me having a solid 40% signal. Net type: will alternate between EHRPD, EVDO A, 1xRTT, and Unknown. Data state: will alternate between "Setting up data connection" and "no activity". It seems like it's looking for a connection but won't connect. I know the signal is there. The only time I can get the 3G logo to light up is right after going out of LTE range, it'll light up 3G for a few seconds and then go out. My coworkers with Sprint have confirmed the new repeaters we have are working, and I've confirmed it won't hook up to 3G at home like my old phone.

LTE issues

Hey guys I dont see this issue anywhere so maybe i got a dud but basically my phone loves to sit on edge for really no reason. I have tried to restart it, toggle on and off airplane mode, switch between network modes, toggle on and off data, and none of it seesm to work. It seems fine most of the time but if I enter a area with edge and then leave it my phone will take a good 10 minutes to switch back to LTE. If I fiddle with it enough I can sometimes get it to switch back to LTE. Im on T-Mobile and for whatever reason it does NOT want to be on anything other than LTE or Edge. Ive never even seen the 3g or 4g icons. So any ideas?
It could be that the LTE coverage in the area you go to is spotty, which is why your device switches the EDGE. As it gets better reception via the EDGE band.
I remember reading in a review that this was a problem for one reviewer. Maybe it's the network bands used that your Honor dislikes or maybe it's just a software issue. If I were you I'd try with a different SIM card from a different carrier that does not use the same network (some carriers share their network).
I think the area you're in, isn't fully supported by honor 8 modem
