Calls not getting through?

Hi,
I'm running my desire with rooted stock rom by oclock (called 3'oclock over at modaco).
Also running a2sd with richardtrip ocv14 kernel, and radio is 32.30.00.28U_4.05.00.11.
A lot of incoming calls are not getting through - sometimes they do, sometimes they don't. People are saying it goes to voicemail 2 or 3 times before it come through. I don't see missed calls on my phone when this happens.
This is with mobile internet set to off, so it isn't that.
Anyone else have this issue? And know how to fix?
Thanks.

Is it possible you could try flashing a differnet radio perhaps?

Are you on he boundary of your network's 3G coverage?
I find I often have to set 3G devices to 2G only in my house because the 3G coverage is marginal and the phones spend half their life jumping between HSPA and EDGE, and it often causes missed calls as you describe. Nothing exclusive to the Desire though, the only 3G device that never had a problem here on O2 was my old TyTN, and that was only because the radio on that was too rubbish to pick up a 3G signal at all here

It happens with my internet set to off though - haven't had mobile internet enabled all day just too see if it was this but it happens when the internet is off.

Your phone will still connect to 3G networks if the data is off. Try changing 'Network Mode' under 'Mobile Networks' to GSM only and see if that helps.

Will give it a go - hope not though cos i like using 3g for emails, surfing etc.
Will also try disabling the "enable always on mobile data" setting to see if that is doing it.
Thanks for the info.

I had exactly the same problem when I used the built in widget to turn OFF mobile data (I had a stock orange ROM in UK). I did this to save battery, but calls did exactly what you said. I now leave it on all the time (and actually battery has improved massively in my 4th week, dunno why, but I went 2 days without charge, and quite reasonable usage!)
Now I leave mobile ON all the time it works no problems, and haven't had the same problems since!

Odd data problem

Ok so I have an unlocked LG Nitro HD with custom ROM (CM10) and it has a very weird problem. I've tried two different AT&T MVNO SIM cards (AirVoice and Consumer Cellular) both have the same issue. My data signal keeps changing from H to H+ and occasionally to 3G like every few seconds regardless of where I am using the phone even outside. I don't understand what the problem is. What could be the issue?

Data does work but it seems to drain the battery with the networks constantly switching and on occasion I get a "No Connection" screen on certain apps, I guess because if I open an app while its swapping networks the app cant connect. It's strange.

They are set up properly.
I had another odd problem, just a few minutes ago was texting someone and all of a sudden phone froze while vibrating then restarted! Don't know if that's a bug in CM10 or what, maybe the network swapping is as well.

Maybe make a backup of your CM10 and try flashing a different ROM not based on CM10.

I think this is the same issue that I recently fixed in quattrimus. I will try to get the fix included in the cm kernel soon. You might try my Rom to see if the fix works.

I tried installing CM9 and it appears to have fixed the problem, the phone doesn't try to connect to the H+ network anymore, only the H network and seems to stay on it so far. I did see it quickly go over to the 3G network but it doesn't appear to be causing any issues, it went right back to the H network. However, I really wish the CM10 ROM worked right, as CM9 is so old...

CM10 is snappy and oh so buttery smooth, I give you that. On another note, did you try any other CM10 variants? I'd give tdmcode's AOKP a spin. He says he might have fixed that problem you were talking about in his build.

I downloaded the CM10 ROM. It seems to behave slightly differently. It stays on H normally, but when I start to do something with data, it will go to H+ until the data loads, then go back to H. So far no disconnects, I'll keep you posted. Right now I have very limited data, I'm switching to T-Mobile as soon as UPS decides to deliver my SIM card (just found out they have a 1900MHz HSPA+ network in my area!) I'll be able to test it better then, but for now I'm trying to stick to wifi, especially since I wasted so much data tonight playing around with this stuff, lol.

Ditto... H and 3g are subsets of each other. Namely they can handle simultaneous voice and data 4G (h+) and lte can only handle data. So it switches back to H so you can receive and make calls plus it uses less battery. If you are on either 4G techs and receive a phone call while downloading it will automatically switch to H from h+ or lte, this is why. The only way you will never see this is on an AT&T rom where it only has 4G and lte icons.

H+ isn't a subset of 4G is it? I know that the CM's have separate icons for 3G/H, H+, 4G, and LTE.

That certainly is debatable but the US's largest carrier considers it to be, it behaves like 4g, H+ may not be as fast but it is 90%+ as fast in most markets small enough to not make a noticeable difference as far as people's perception and the technology behaves like LTE in a lot of respects, CM is international so it just conforms to International norms so that's why you get H+ AND 4G (LTE) designators.

Possible to disable LTE on AT&T on AOSP ROM?

Is it possible to disable LTE on AT&T using an AOSP ROM?
I've tried the rat restriction method and the wap.cingular apn and neither worked.

No. Not yet anyway. So far the rat restriction works only on stock TW. As far as wap.cingular, I have noticed that it no longer works either. I think AT&T did something that seemed to disable it.

My LTE toggle on CM10 works fine using the UCDLK3 modem (or whatever it is). The settings update from "WCDMA only" to "LTE/WCDMA/GSM" when I toggle it (just to confirm). I haven't updated to CM10.1 yet, but last I tested it the LTE toggle did not work.
On CM10, I did have to go into Settings and find the Mobile Networks option (its on the same page you enable Data Roaming) and select an AT&T network once. The toggle would not work if I selected "Select automatically". My phone is also unlocked using the dialer code that was posted for ICS 4.0 ROMs - not sure if this matters.

You can on AOSP.
System Settings> More> Mobile Networks
Now go to Network Operators, Might take a couple of minutes to scan, once a list shows up. Select the first option.
Now go back and choose the wap.cingular APN.
Also, if you want to get on 2G, the "Use only 2G Networks" is now able to be checked as well.
These options will reset after a reboot and toggling between Airplane mode.

Interesting so you just have to do the network operator thing? I've gone into that menu before and tried to check 2g and it never let's me, but I've never gone into network operators section. Will try tomorrow!

Holy cow it worked broseph! I went into Network Operators. It took about 2 minutes to load the list, then showed three AT&Ts and a T-Mobile. I picked the first AT&T.
Then I tested 2g by putting a check mark in the force 2g box, and sure enough, it worked. I then chose GSM/WCDMA preferred, and sure enough, it forced HSPA+ without even having to choose the wap.cingular APN (in fact, I am using the "phone" APN).
Any downsides to selecting the network operator that way? I'm pretty sure AT&T does not roam onto T-Mobile in any event, so off the top of my head, I can't think of any downside. Would be curious if anybody can think of any downsides to forcing HSPA+ this way.
I personally will probably leave it on LTE most of the time anyways... I just wanted a method to force 2g or HSPA for the few times that I am in a location with weak LTE and the phone kills its battery by switching back and forth between LTE and HSPA. Awesome to finally have one.

Yes, it works. I use this all the time. No need to change APNs either. I've never noticed any problems with this. Once in a blue moon I have to go and redo the network operator part but I've never figured out the exact reason. I have a MicroCell due to poor coverage so I often elect to turn off LTE at home and re-enable when I'm out and about. I've also traveled all over the country and never had an issue I would equate to me manually selecting the network operator.

Haha yes reading back to your original post that is basically what you said. But since you didn't say "network operator" it didn't register for me even though it's now clear that's what you meant =P

Thank you. Now I can finally have my "cake and eat it too". Did not even think to try these methods. Thank you for your information. This is so much easier than on stock rom...with the goodness of all that is AOSP.

I just did a test to see idle drain overnight on HSPA and it was actually worse than LTE. On LTE I drop about 7% overnight. Last night on HSPA I dropped 12% in 9 hours. Better battery stats showed 98% deep sleep, too, which is about the same as on LTE.
Anybody else ever try this? Curtis if those results are normal-i would have expected less drain on HSPA.

My signal was about -70 dBm (ie, very good) and better battery stats showed 98% deep sleep.
In any event, it was running the same apps as it was the night before when it lost only 7% on LTE. I'm just surprised LTE idle drain was less than HSPA under identical circumstances and was wondering if anybody else experienced the same?

It could be coming from your carrier and their towers. If you really wanna save battery, set it to 2G overnight. Also, 4G is only a battery drainer when it's being used, which it isn't much overnight.

+1. I set to 2G every night. Of course I also always have switched off data and wifi because I don't care about emails and other misc stuff while I sleep. I have slightly better 2G reception in my home than 3G or 4G so this helps even more on battery savings. Cut my battery drain nearly in half (6-8 hours I may get a 3% drain or an absolute max of 4% if I keep snoozing my alarm).

This doesn't work on my AOSP device, I cannot change Network Type or check the "Use 2G Networks only" box. What am I doing wrong?

Wow this works
I think I've always been too impatient to wait 60 seconds for the network operators to load lol
But props im not sure if this is recently discovered but I've spent a lot of time searching for how to disable lte and could never figure it out.

Actually, got it to work. Picking the second "AT&T" from the network operator list allowed me to toggle the other settings. This is a big deal for me because my area has "partial" 4G coverage and my phone prefers a poor, slow 1 bar LTE signal over 5 bar HSPA+, thanks a lot!

wap.cingular will go in and out every 5 minutes and when i enable wifi and turn it off, it takes a good 1-2 minutes to regain connection. (On TW)

[Q] Bell Canada i747m losing connection

hey gang i'm running the latest aokp task650 build on my S3 I747m. Everything works awesome, except i occasionally lose my data connection. I'll notice my connection status bars are gray, and typically a reboot will fix it. I'm sure going into airplane mode and back out from that would re-establish the connection too.
my APN is set correctly, i compared it to a friends nexus which is not rooted.
Right now i'm set as pda.bell.ca
I've flashed the latest bell modem file (that i'm aware of).
Anyone have any suggestions? i'm pretty new to all of this.. not sure what to do to troubleshoot.

I've been having problems lately when I have poor 4G (LTE) signal. My phone would rather hang around on the LTE network with little to no signal before it switches over to 3G. It's been doing this for a while on the Rogers network for me. I can see when I check the battery stats just how much time is spent without signal which is a lot. At work I get full bars 3G when at my desk but very poor 4G. The only thing causing me to loose signal is the poor transition back and forth between the two networks. Changing modems has absolutely no affect on this matter and I've put the APN's and network modes through the ringer with no change either. I've tried it all and nothing improved it. When I walk outside I immediately hit full bars 4G. Just when I'm inside my work and at home, I get poor lingering 4G. I wish the thresholds for when it switches over were better. I usually just turn off LTE all together which sucks but oh well.
I don't think we are the only people with this either. I've read grumblings about others noticing the same thing.
If curious, I'm running the latest CM10.1 nightly with Ktoonsez kernel on the Rogers network in Ottawa.

Interesting, that could very well cooincide with what i'm seeing. I tend to bounce from 4G to H+ or 3G, i wonder if it's trying to hang onto 4G.
Is there a way to force it to stay on 3G? that might be a good test

I was getting the same issue.
I did a factory reset and reinstalled my ROM plus GAPPs and the issue resolved itself.
I am using the latest modern right now and not my bell one. I think it's from a south American carrier, but bit 100% sure of the top of my head. But it is in the current modern thread

Missed calls not showing, and late SMS

I'm having issues when on WiFi and LTE Enabled, the phone does not get any phonecalls, missed phonecalls do not show and SMS arrive late (my carrier has the option to notify me missed calls, but yesterday the message got me 10 minutes after the call).
After searching, I've found out something similar happened to nexus 4-5, when WiFi is ON, LTE is ON, and the phone is in Sleep Mode but nothing on Zenfone 2. Have a friend with ZF2 that confirmed it happens sometimes but we doubt if it' s a phone issue or carrier issue.
Getting the network mode to 2G/3G seems to fix it, but it misses the LTE

try to restart the phone (?)

I reboot my phone every couple of days, but the bug sometimes appears in the phonecall right after rebooting

What messaging app are you using? I know I miss messages from my wife when I had textra in the "off" state with autostart manager. When I told it to start when the phone boots it started getting the text messages and mms's right away. Are you using a VPN or do you have weak signal and what firmware are you using?

make sure phone is allowed 2g/3g/4g all. If you restrict it to 4g only you will face such issues.

I usually reboot in the mornings. But I US Google voice so the issues never really show up.

Stock FW (was on 168, now I'm yesterday patched versopm) , Stock SMS, no VPN, and set to 2G/3G/4G
As I said, the problem is fixed when I'm on 2G/3G, but it kinda loses the point to have an LTE plan

can you test with 4g on and wifi off.What carrier are you on. Because carriers can use wifi and lte combo in case you have same carrier providing both facilities.

I'm on Uruguay Antel and it does not offer any combo whatsoever, voice calls are usually switched over to 3G when I'm on LTE, but somehow the network or my phone fails to switch sometimes
