Phone signal question

Anyone experience no phone signal after flashing a ROM to your Pure? I got the device two days ago and immediately went to flash it using one of Duttys roms and also from Tess (IV). With both attempts I get no signal bars whatsoever. That being said I get an "H" where the "3G" used to be. I know that some of you have talked about the HSDPA but even though I have been doing this awhile I am stumped as to why I would get no signal bars. As long as HSDPA doesnt result in more charges from my provider I could care less about that. Hope that makes sense and I hope that someone has some information for me!
Thanks!

Hi, yes, I have seen the situation on some ROMs where I get 'no bars', but the phone seems to be operational anyway. My suspicion is that it's a problem with the root software from Microsoft, not the ROM chef, since it goes across ROMs.
3G vs. H has no bearing on the problem. The H just shows that the phone is connecting via the higher-speed data linkup. Some providers charge more for H, others don't. You'd have to check with yours.

Thanks for the quick reply. Is there a way to figure out if AT&T charges extra for the "H" connection speeds?
Also, are there any roms out there that have figured out a way to slightly increase the size of the virtual keyboard for easier typing? Both roms I have used so far have kept the keyboard the same and not sure if there is actually a way to increase the size. Lastly, I am reading up on roms trying to find one that I would like but one piece of information eludes me. Does the rom I am researching support landscape mode in Start and all other aspects? Right now I get landscape in web browsing, email and that is about it. I may be missing something here but thought I would ask for clarification.
A note about the Tess IV rom is that I really loved it. It was super smooth and very fast unlike the shipped rom from AT&T.
I found the original rom to be bulky and slow in responsiveness when moving between features or applications. I am sure that is why others moved away from it as well.

AT&T does not charge extra if you enable HSDPA. This is my second AT$T WM device and I have enabled "H" on both.

How do you enable "H" or force it on?

The type of signal is dependant on whats available in the area you are in. As far as I know you don't force "H" to come on, your phone just accesses the best available signal you allow. If " is it then.....
My att plan is the basic plan with the $30.00 data (unlimited) that is required when you buy it. No charges for "H" access for me.. good god, with the way I use slacker all the time, that would bankrupt me in a week.. lol

I'm using the ENERGY Leo ROM, and notice the same.
Thing is that while H is showing I get no bars and no phone connection. Then the phone automatically switches over to 3G and dials out. This can take up to 10 secs - so, can be annoying!
Could this be a locational thing, as I notice this happening in one location only - perhaps where the signal is not strong enough to utilise the H connection.
Or, is it that H is used for data and 3G only for telephone calls?

H is actually HSDPA and is the 3G data connection. 2G equivalent would be EDGE for example. You will only pick it up if A) Your device supports it, B) Your carrier provides it!!, and C) Your are in a stong enough signal area.
You mention that you flashed to a custom ROM but have you flashed your device to an updated Radio ROM? This is the part of the phone that deals with communications including Voice, Data, WiFi etc. Using a good one makes a world of difference.

No, I thought the updated custom ROM would also update the radio.
What is your reccomendation for the radio?
How do I find out radio version I've got?
I dont have any specific useage beyond taking calls, and updating Twitter, weather etc.
What version do you think is best?

Some ROMs do include the radio, such as Dutty's HG 9 & 10 ROMs.
The radio version is usually included in the name of the ROM.
For best radio, it depends on your carrier and location.
To find your current version, soft reset, it is listed at the bottom next to "R" upon booting.

I checked my radio ROM - it was .17.
Just updated the radio to .91 - immediate improvment in access to 3G cellphone signal.
Of course, I need to use it for a couple of days to get an accurate feel for improvement.
BTW. I'm based in the UK.

I've had varying success using different versions but .57 has always been head & shoulders above the rest for me.
As always your mileage may vary

[Q] Worth buying Droid 4 as GSM phone?

I thinking about buying D4 as my prime phone. I already find out that It supports GSM and how to unlock this feature. But is it worth to buy this phone to work on GSM? I noticed that there are many issues with it:
- not working callout on 3G on Android 2.3
- Verizon lockscreen that wants to activate phone
- problems with APNs
etc.

Yes! It's definately worth it!
The 3g callout problem is a temporarily thing, I'm sure of it. We're still playing with settings and drivers to fix that. In the mean time I use my phone on 2g for voice and 3g for iinternet. With one press of a button I can switch between 2g and 3g (There's an app for that )
The verizon lock screen pops up only once. Once you skip it, it doesn't return until you reset your phone to factory defaults.
Problems with apn's? Depends on your provider. I didn't have any problems at all.My apn settings were transferred automatically to my D4 when my provider detected that I was using a new phone. Even after installing different roms.
I'm using my D4 a couple of weeks and everything still works like a charm.

Mainly I work on 2G because of battery saving (it last for much longer!). But bug with callout has been patch in leaked ICS and what I heard it don't have Verizon stuff installed. I can't wait that some CFW ICS would use its libraries and kernel.
Unfortunately for now I can't afford on buying it because last 10 days jump over 10% according to my currency so it, when previously it had very good price then now it isn't.

I love it. I'm in Canada on Bell Mobility and everything works perfectly on Gingerbread, including outgoing calls on 3G. I think the voice issue is only affecting those within the USA on other carriers such as AT&T.

Whats the difference in using 2G or 3G for voice calls?
Isn't it the same?
Also, I wanted to use this phone on AT&T in the US. I just have voice and texting. Will this phone work for me?

Hi there,
did you have the chance of direct comparison to the Droid 3's signal quality, 3g speeds and call quality? I may consider importing it, but still not sure.
THANKS

It seems to work just as well as my Droid 3 did. The only issue I have is that the Droid 4 seems to underreport the signal it is receiving in the status indicator, the highest signal I've been able to see is 3/5 bars but it still seems to perform as if it were at 5/5.
I'm sure it is just tampering by Verizon and doesn't hinder the device's operation at all. I haven't tried any of the AOKP ROMs yet but will report back once I get a chance to install one.

Thanks for the reply!
Thats interesting, it's like the Droid 3 cheating on us that the GSM Signal would be very poor. Would you please have a look in the build.prop if there is a value ro.mot.phonemode.vzwglobalphone and set it to 0? Then prove if the signal gets better?
News about Droid 4 GSM unlocking this summer:

Interestingly enough, in the ICS build just leaked that has global support enabled by default, that value is set to 0 in the build.prop.
I am in the US and a VZW user, so I can't test the GSM radio performance on the D4 because they have disabled it for US carriers via another band lock or other mechanism.
I have been dumping and comparing the NVM of the various builds to try and isolate any critical differences to find the key. It may not, in fact, be in the NVM at all, but elsewhere in the radio image.
Just an FYI.

There is difference in voice codec (on 3G you should get better quality, but it also depends on the second side). Also at 3G you can use front cam for video conferences.

Yeah, the first thing I did once I could was look at the build.prop settings but I noticed that ro.mot.phonemode.vzwglobalphone is already set to 0, with a note in the comments above it that "the definition moved to cdma_maserati.mk to support different config for factory", which suggests that maybe their tampering is a little more hard-coded into the Blur interface.

[Q] HELP UK model with serious signal issues on ATT in the USA

Hi all, well my One arrived from the UK today.. As I feared it does not have the ATT LTE bands that PDAbd.net suggested it had, bummer, but I can live with HSDPA... Set up the phone, it asks me to select the operator I am unsing, with ATT as the first choice... all goes well.. I load it up and initial impressions... WOW.. what a great phone.
BUT and and very BIG BUT.... the signal is terrible... bouncing from no signal to 2 bars and displaying H one minute, 3G the next and then E...
Driving down a notorious road it drops the call at least half a mile before typical and doesn't pick it up again until even later..
Does anyone know if there are any setting I can adjust to optimize to ATT?
I really do not want to put it is back in the box, but unless someone has a suggestion for me, I have no choice...
Help!!
Many thanks,
Nick

A quick question. Where did you get your HTC One? And have you used any other HTC Phones before and got good signal with it?

Hi There,
I bought it in the UK. It was a legitimate HTC supplier and an unlocked model 801n.
I have used a couple HTC phones in the past:
ATT 8X - worked well (at least as far as signal was concerned, but that was the ATT model)
I also had a Verizon Incredible, but since that is a different provider, I am ignoring it.
Other phones I have right now adn tested in the same location with the same SIM:
1. ATT - Galaxy note 2 - good signal no issues
2. ATT LG Optimus G - Good signal no issues
3. ATT Iphone 5 Good signal no issues
4. ATT Nokia 920 - good signal no issues
5. Blackberry Z10 - unbelievably good signal - no issues - Unlocked ATT bands, not ATT branded (Purchased from Expansys USA)
This is why I am wondering whether it is some kind of optimization issue. I cannot believe HTC could have made such a mistake in design. Also, if I switch to GSM only, I have full bars.... It is only on 3G and HSDPA that the signal is poor and the display oscillates between 3G and H
Any advice?
Many thanks,
Nick

Are you rooted? The solution is disabling fast dormancy on HTC One. New HTC devices enables fast dormancy by default which affects & weakens signal strength on networks that doesn't support it yet. If not I am not aware of any ways to disable it without root yet. I'll update you if I find one.
On UK almost all networks do support fast dormancy already except for Three UK so that maybe the reason why it's enabled by default in the US however I am not aware of the implementation of network carriers there sorry.

No I am not rooted - what will I lose if I root it? Do you know of a link to a simple thread with rooting instructions and how to disable the fast dormancy? I am not super experienced with Android yet
Does anyone know whether ATT supports fast dormancy of not?
Also, I have been led to believe that the One supports a number of carrier frequencies, but they only enable those for the specific region it is sold in. Do you know if there is a way to enable the other frequencies? Or is this just an unfounded rumor? Also, do you know if there is a way to check which LTE band the phone I have is equipped with - Not an on-line reference, but a way to find it on the phone?
Many thanks!!

Your warranty if you mess something in the software's side like bricking your phone & OTA updates. But you'll be able to update anyways just by directly flashing on the phone.
Anyways here's a noob proof app to rooting. Please do some research first before going so you'll not mess this up.

Check this regarding what is Fast Dormancy and tell us if it works(probably NOT (it works only to samsung phones) but it is easy to try) http://androidforums.com/samsung-galaxy-s2-international/674208-fast-dormancy-in-nutshell.html

You mind sharing the link if they have stock? Good luck with the signal issue.

I had a friend with an international GS2 with the same problem. Constantly bounced from HSPA+ to 3G to EDGE to no signal. I'm 99% sure that the issue is network settings, you likely need to check SIM card, data plan provisioning, APNs, etc.

Hey, thanks - Do you know what settings I should use? I have an LTE provisioned SIM card...I assume that should be ok, since the phone is LTE enabled, just wrong bands? I have tried with Auto LTE on and of - I currently have it on GSM/WCDMA - it has been working better the past day, but it is still not right..
The SIM works perfectly in the Note 2, Optimus G etc. So I am wondering whether I need to look at the APN or something like that, but I do not know what the best settings should be. Anyone have this info?

APN shouldn't affect your mobile signal reception. It's just made for cellular data profiling. So you are able to connect to the internet.
How about try setting your network selection mode to manual and just select the top most usable network there?

Interesting... I am in Korea right now and have great signal... no issues at all. However, my data indicator is still bouncing between H and 3G, so that is very strange...
Despite the indicated low signal and bouncing data connection type indicator, the phone is working well, have not dropped a call recently and excellent phone call quality...
NO LTE connection in Korea though.. I assume that is probably due to ATT not having a LTE roaming data service agreement here? I believe my phone has at least one LTE band that it supported here.
Have fun..

I think u should talk to att people may be they can help? With the signal issue or the data connection issues!

? Question about Verizon and data roaming

Using my N6 on Verizon, I frequently get messages that I have left my home and dont have data roaming enabled. I don't understand because my note 3 had no problem with Verizon. If I turn on data roaming for data might incur charges from some other provider? On the status bar it used to say either T-CDMA or Verizon Wireless, now it says 3100. My SIM is the same one I used in the note 3. If it matters I am using Liquid Smooth ROM and Franco r2 kernel. Voice seems to work. Any suggestions are welcome.

I'm having the same problem. I have to keep going back to stock to get LTE. I've tried liquid smooth, validus, and bliss pop and all gave me roaming and no LTE. All are their latest builds too. I've also tried popping in and out the sim card with reboots as well.

That is exactly what I am seeing. I'm on WiFi 99% of the time but when I leave the house I have no data.

Good ole Verizon making it impossible to do anything without them approving first. Its probably because Verizon doesn't want people to use the phone on their network before they release it.
They've never been good about nexus though. If you don't recall the whole galaxy nexus debacle

I had the galaxy nexus on Verizon but don't recall them interfering. I do hope that once they offer the 6 that our network access is unfettered, or the community will figure out how to make it work with custom ROMs.

Your roaming goes away? I can't run any ROM without roaming on Verizon...

I noticed this issue on CM based ROMs. Any that are stock based are not effected by this bug, for me at least. I have spent a couple of hours trying different things out that people suggest but none of them have worked. I was able to get 3G to work on liquid, but no LTE. and it reverted after a reboot. I sure hope someone can get this fixed soon.

im running cm12 on my n6 and using verizon and it works perfectly. No issues.

on Bliss Pop the Status Bar icon is NOT roaming but if you pull down and check the tiles it says roaming. I dont think its actually roaming though...LTE Discovery tells me I am still LTE and so does Network Signal Info.
So I think its just in the UI.

You think it is still on vzw when it thinks it is roaming. If I enable roaming data I won't get a huge bill from some provider?

Well, I cant swear to it for sure, but I from the apps I have I am still attached to the same cell tower, so not sure how that would equate to roaming.
LTE Discovery also shows as roaming, but all the other info also shows LTE. Same for Network Signal Info.
IANAL , but if your attached to your normal home cell towers, it would be hard for us to be roaming I would think....and hope

It may have to do with LTE vs 3G. When not on LTE it says 3100 (or 31000?) and that bus when I am "roaming". So confusing. I've gone back to stock rather than Liquid Smooth. I will try an AOSP ROM like Pure to see what happens. Although I'm not missing much on stock.

So all I can add is that I just looked at my bill which ended today. I have been using BP for the last several days at least, and I have 0 roaming charges FWIW YMMV all those caveats....I have a Nationwide Talk 450 Min plan with the standard 2gb data.
HTH, but remember I added the caveats, caveat emptor

Any update?
I have same kind of problem too. Im afraid the bill will goes up by this.
Please let us know if there is a fix for this

Yeah same problem... I don't get why some Verizon users agent having the same problem. Would unrooting and doing a factory reset maybe fix the problem? Frustrated that I can't run a custom ROM without roaming...

Go take a look at your bill/usage online and see if things are showing as roaming. like I said mine looked fine. And it seems like an issue with quite a few roms from understanding.

I just tried out Broken and it has working LTE on Verizon! I'll have to look at my bill, haven't been on a custom ROM with roaming in effect for very long though, so I probably wouldn't be able to tell very easily.

I have a Stock Rooted, Unencrypted N6, with a few custom Tweaks. On VZW have not had ANY issues whatsoever with my service or LTE. Perhaps some custom ROM/Kernels might be causing these issues?

Stock seems to not have the issue. It is said herein that AOSP based ROMs don't either but that is not true in my ecperience. LTE Discovery says 31000 is Verizon Wireless so I believe that even though it thinks it is, it isn't roaming from VZW. I enabled data roaming and switched back to Liquid Smooth and I should be alright. Thanks to everyone for the insights.

I get zero mobile reception at my work so for over a year now have been using the Three inTouch WiFi calling app which has been pretty good, however last week I received a message saying that due to upcoming network upgrades Three will be retiring the app in a month or two so I now would like to be able to use Android's native WiFi calling if this is at all possible.
Three's website says that WiFi calling is only supported on Android on handsets purchased from them on contract, however I'm a SIM-only customer. I've got the latest OxygenOS modem firmware etc. installed as far as I'm aware, so was wondering if any of you clever people here on XDA have managed to find any unofficial ways of getting the native WiFi calling working for any old network?

Wifi calling is working out of the box for me. VoLTE too*. (LOS+3+SIM only+OP3/T) Been working with that setup since the beginning of LOS16.
*With 3 you'll only connect to VoLTE when 3G is unavailable as they prioritise in that order. For some reason they don't like people to use 'Super Voice', even though they advertise it as a feature. There's a big thread on the Digital Spy forum covering 3 and 4G in the UK that you might find useful.
Edit: Try the field test number. Enter *#*#4636#*#* in the Dialer. Is Wifi Calling 'Provisioned'. See my own screenshot:

On my stock op3t there is no WiFi calling toggle to switch on. That probably explains why I don't have it despite being able to switch it on under enhanced communications under sim settings.
Is there a way to activate it? The volte calling I got by doing a code thing.

Yes the "Wi-Fi Calling provisioned" toggle is on.
I've just upgraded to the latest LOS 16.0 nightly (2019-05-02) but still no sign of the native Wi-Fi calling working.
You said you've had it working since the start of LOS 16.0. I upgraded to 16.0 over-the-top directly from 15.1, do you think that could have anything to do with it?
Are there any settings in the SIM itself which could be needed to enable Wi-Fi calling? I think my SIM is a good 3 years old or so, would swapping it for a newer one be any use do you think?

What exactly are you doing to test that it's working or not? Have you made a call with Wifi on/Mobile signal absent?
Is there anything particularly unusual or unique about the Wifi network you've been trying this with? Have you tried other Wifi networks?

I've finally managed to get lineage 16 installed on my phone but I still can't get WiFi calling with my three sim card. The settings seems to be the same as yours. Not do I have the icons for WiFi calling or wokte at the top of the screen which I had with oos 9.0.6.

My flawed testing. I'd forgotten about this thread. VoWifi is a no go. VoLTE works, but with Three caveats. See what i posted here:

Thanks for the update. I better get a new phone soon despite mine works fine outside my home (were I am now locked away for the foreseeable future).
Saw something about a volte wowifi module on one of the android ten ROMs but not sure if it just enabled volte. Thing it was the havoc ROM

OcUK. User name looks familiar.
We're having this conversation in multiple threads.
VoWifi does NOT work, despite any previous assertions to the contrary. As i mentioned, it was flawed testing methodology.
VoLTE does work, but with Three network restrictions. i.e only when there is no normal 4G (1800Mhz) or 3G available. VoLTE is only carried on the 800Mhz band, which is prioritised lowest.
There are two very long Three 4G threads on the Digital Spy forums. Worth reading if you want the long version of what i have stated above.
Edit: Just a suggestion. Try this app so that you can monitor what Bands you are connecting to at any given time:
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en
What you need for VoLTE to work is Band 20. (800Mhz)

I posted the link here as I thought it was more relevant here.
The app is telling me I have band 20 so volte should be achievable but doesn't seem to be working on lineage (worked fine on OOS 9.0.6)

To save time can you post a screenshot with the App displaying that information?
'Connected to Band 20' is what we're looking for, rather than 'is available'.

I'm guessing this is the screen you want.
I also installed VOenabler v1.7 which seems to have restored volte. I haven't seen the volte icon but I'm still at home.
Edit: I installed the module before installing the bandwidth app.

Double post..

It looks like you have Wifi turned on in those screenshots. If you turn it off you should be able to make a VoLTE call. At least it looks like you should.
So has 3G always been bad where you are? I assume you don't have 3G or normal 4G reception at all? (Bands 1 & 3)
I almost always connect to one of those two in my area, although where i am now it looks like some neighbouring towers do carry Band 20. I just need to destroy the other towers to connect to it!

It's abysmal. I'm in a Victorian basement. The only reason I went with three was the WiFi calling app.
Have left the house now for some air and now I band 1 so I'm guessing I'm connected to a different tower.

So what you're seeing is evidence of Three de-prioritising Band 20. As 800Mhz has better building penetration it's all you're getting while inside. When you step outside you begin to pick up the other Bands which you are immediately switched to, whether you lke it or not.
I only latch on to Band 20 once in a Blue Moon. The coverage of the other Bands is almost total so i don't stand a chance!
VoWifi is another matter altogether. If it could work with the 'intouch' app there must be something in the app that could be added to our ROMs natively. That's my logic anyway. (Also support is added to phones bought from Three using their official ROMs, so the same logic applies).

I thought newer phones had WiFi calling by default and didn't need to rely on the carrier.
That's a very good shout but way beyond my skills. Maybe it can be suggested?

This is the official word from Three:
http://www.three.co.uk/Discover/Three_inTouch
They say 'update' which suggests that people who bought phones on contract might have received an OTA which enabled VoWifi. How much would we love to get a copy of that OTA zip!

Poor us who bought our phones right out. I wonder if this is the case for newer phones too.
There must be someway to get that zip!
