Calls not coming through

Hi, gang. I've been surfing the forum silently for a little while and got my G1 all rooted and hacked the other night. It's been awesome and thus far I've been able to resolve any issues I've had in the process.
This one is throwing me off but I know someone has run into it before. Sometimes when someone calls me, they say that it rings twice and then goes to voicemail. I never get any missed call notification or anything. It's like the call never existed. After testing, I found that data transfer is taking precedence over voice data when they both try to come through at once. It's really annoying!
Does anyone know of a way to reverse the importance of these 2 things? Obviously I want to receive my calls if they happen to arrive when data is transferring. My phone constantly accesses some sort of data throughout the day (only texts and email).
For reference:
- White T-Mobile G1
- ROM: OpenEclair v1.2.1 BACONWEAVE
Thanks in advance.

No one else has run into this? A friend said I could try a wipe and re-flashing the ROM and see if that works. I'm thinking of going back to Cyanogen and seeing if the problem occurs with that.

Roaming in Citrus Springs?
Check Settings/Wireless & Networks settings/Mobile network settings/Data roaming. The choice is to connect to data services when roaming. This should not be selected.
Regards

David,
I totally overlooked that setting. Before my phone was rooted, I apparently had disabled this but failed to do so after modding. I just tested it by loading a website in the browser and making a call to it while it was loading. The call came through without a hitch!
Thanks a lot. I had searched high and low but no one ever mentioned this. I thought I had already tried it actually, but I was wrong. Much appreciated.

Okay, apparently it was only a partial fix. If wifi is enabled, the web browser just defaults to using that (obviously). When I disabled wifi and loaded a webpage while calling the phone, the call went to voicemail after 2 rings and never showed up on my phone.
I've never had this happen before. I've only seen this after flashing everything required to root the phone. It's not a huge deal but it baffles me. I guess when you're not on 3G, it only allows data through if both voice and data are trying to transfer at the same time.

Help, I can't receive any calls but no problems to make them.

Hello, everyone.
I need help with an issue I'm facing. My phone is not receiving any calls whatsoever and I don't know why. I can make calls without any problems, the issue is that I can't receive them.
I don't know when this started happening since I don't receive many calls, I don't know if it's a result of rooting the phone, because it's rooted, or what else can it be. I don't remember if the phone received calls before or immediately after being rooted.
I've tried flashing different modems but I haven't been successful. Also, I have gone through the settings and disabled everything that could be causing the calls to be blocked. I have also called T-Mobile and they disconnected and reconnected my phone to the network and I have gone to one store to have the sim card replaced and that didn't help either. I have wiped the cache and the Dalvik cache and nothing. The only option left that I know is to factory reset the phone wich I'm trying to avoid because I have a ton of apps and my home screens are already setup and folders created and I don't want to do all this setup again.
Here is the weird part. Under just this specific scenario I can make my phone receive calls.
Make a call to any phone
Hangup a couple of seconds after the other phone starts ringing.
IMMEDIATELY BEFORE the call is terminated (lost) dial from the other phone (the one that was called in step 1). This should be within one second and no more after the call is lost.
If I follow this procedure then the call goes through and my note 4 receives it, but the call shall be made immediately after I hang up, otherwise it doesn't go through.
Does anybody have an idea of what could be happening?
Thanks!!

try this, go to settings all the down to calls and click on call rejection which says auto rejection turn that to off, ive had the Same problem and thats what help me out

Texts stuck "sending" and other issues

Ok everyone figured I'd come here to where the experts live. Haven't been here in awhile.
Recently my S8, wifes S8, and our sons S8+ all have the same issues.
The first issue is texts get stuck "sending". This happens with WiFi on or off, with wifi calling on or off, and I even tried changing off LTE to just 4G/3G/2G and even 2g in settings to see if that would help. I'm on the latest firmware from TMO ending in QEF, well we all are.
The other one is apps like FB and others aren't alerting but they will show the number of alerts even after they've been checked. I've reinstalled these apps and the problem persists, and then I can reboot my phone or wifes phone and all the alerts start working again for awhile and then die eventually.
The texting issue though persists and is random when it will hang and when it doesn't.
According to TMO rep at the store it's a bug in the firmware with bixpy that was pushed out, but I frankly don't buy it and figured I'd hit the guru's up here and see if you guys have any thoughts.
Thanks in advance guys and gals....

I too have had the random "texts get stuck sending" issue. I haven't had it in a while though (now that I've said that I'm sure I will).
I unfortunately don't have any suggestions.

I ended up using googles version of messages due to this. Only on stock text app do i have any problems anymore. I also noticed on the stock app that my phone would say "sending" when the other side would actually get it, but it was at random.

You don't have a cellspot repeater or router do you? Last time I had it, my device was hung and needed reboots. Just a thought.

Thanks for the feedback, yes I have a cell spot, but I also have the issue other areas of town too with no real specific place thatbit always happens.
I'm going to reverse back from the qef firmware and see if that resolves things. This has been so annoying, and it just started about two weeks ago.
Thanks again everyone.

I have had the same issue with sending texts too. I have been using the stock messenger app. I may just switch to textra.

Same issue here. A temporary fix, try turning on airplane mode and off. Works for me a times

Also happening to me on the XAA firmware (have unlocked NA variant) with the stock messaging and Google messages.

So I'll ask the question begging to be asked (at least by me): How does one disable this messaging app and use "stock messaging" app?
Thanks in advance....

Just get a app disabler for Samsung from play store like BK Disabler.

If I were you, just download Android Messages. It's simple and fast.
However, I do not recommend disabling stock messaging, unless you don't like getting EAS (Amber/Weather/Presidential Alert)

Having the exact same issues and it's driving me crazy because I really like this phone. I don't get notifications for any of my apps but when I open them I can see the new messages. A reset seems to fix the problem but it only lasts about an hour before it starts doing the same thing. I've tried using different messaging apps but the same thing. And the fact that I don't get notifications for other apps it can't just be a text messaging issue right?

Happened to me for almost 2 months but haven't had an issue in about a week. Called t mobile, they created a ticket and said they'll be working on it. Few days after speaking to them, problem went away.

This has been happening intermitantly for me as well. It's been bad the past three days. I'm currently in coversations with T-mo's engineering team and they seem to be coming up with a bunch of dead ends. It's not a location based thing as it's been happening over a 20 mile radius in the past few days for me. Other people on T-mo network that I'm freinds with or I work with aren't having any problems. I'm wondering if just a fresh SIM card could solve it?
I have data connection although it seems a little sluggish compared to when I originally got the phone. Similar to OP I've tried all the "G's" modes, with wifi calling on, with it off, with cellular network preffered with wifi calling on and off. With Textra, with stock messaging app. I've factory reset to no avail. I've pulled and re-inserted the SIM card to no avail. This is incredibly frustrating for a flagship phone on a network where I've had no previous issues.

UPDATE: T-Mobile sent me a new SIM card and that seems to have cleared up the issues. Not sure if it just hapened to coincide with T-Mo tower fixes or anything else like that in my area but I'm back to normal operation. Anybody else experiencing this I recommend you push customer service to send you a new sim.

my husband and i are having a strange issue where we can message pictures and video clips to other people that don't have the s8, or aren't on tmobile and they'll send and receive just fine, but when we try to send to each other, the first attempt to send fails, but the second attempt goes through?

Sometimes Cannot Make or Receive Calls

Hello guys,
Sometimes I cannot make or receive calls. When that happens and I try to call, the call attempt immediately ends. I still have good cellular signal, I don't have call barring, call blocking, Wi-Fi calling.
Turning on and off Airplane Mode solves this but the problem reappears from time to time and I don't even know it until people tell me that I am unable to be reached. I have Android 10 with One UI 2.1
Also, I used the current SIM card in my older A5 2017 phone and experienced no such problem.

Question S21 Ultra sometimes doesn't show that someone is calling me

Hello,
For many months I have had a strange problem with my S21 Ultra, namely it does not seem to show me at random times that someone is calling me, no matter if via the cellular network or some communicators, it simply does not show notifications that someone is calling no matter how is calling. I often have it that only when I pick up the phone, unlock it and check something on it, suddenly messages come that someone tried to communicate with me, and only from then on I can answer calls until I hang up the phone and in an hour or two the same problem - over and over again. I have such an impression as if the phone itself went into some hibernation after putting away, although I have no indications that something like this is happening, because everything looks normal. The phone has the latest update, and I have restarted it several times with no effect.
I would like to add that this happens both in an apartment where I have wifi turned on (I do not use lte calls), and when I am outside while walking in the city.
Is there something I can do to fix this?

This is a very strange issue indeed. Have you checked if your phone has cell coverage when the screen is off? Did you try calling yourself from another phone and number? If the answer is negative to either question, I would suggest resetting your network settings. If that fails, try a factory reset which should solve any issues. If the issue still persists, it could be hardware related and you might need to take the phone to Samsung centre to get it checked.

I don't have a second phone to call myself. Friends say that on their end it sounds like I am not answering the call (i.e. they have a call signal, but just nobody is answering). They have no busy or unavailable signal. What exactly do you mean by a network reset, what would I exactly have to do? I was thinking about a factory reset, but I'm afraid that I will lose all my data and application settings. I do not know if it matters, but I have been using this phone since the premiere of the S21 Ultra, and when I bought it, I transferred all data via the data migration service from the previous S10+ phone, to which a few years ago I similarly transferred data from the S9+, to which I transferred data from S8 + earlier

Maybe you have the "do not disturb" option on? When I have this on, I can't see who is calling me.

I checked, unfortunately it's not that, if it were, I would never see someone calling, but my problem seems to be random.

u need to go to settings>general>reset and there tap reset network settings..

Hi,
I experience very similar problem. I tried to reset network settings, "hard" reset the phone, playing around different mobile network settings... nothing helps. I'm not sure if it is phone hibernation issue or kind of removal of the phone from cellular antenna.
I have another phone I use to watch this s21ultra issue. Practically each day it happens that the s21 ultra does not react to my call, of course most of the time it works properly, but there are some tries, when it fails. In such case on the phone I call from I get a message "user is not available". But then, leaving the s21ultra untouched for 10 minutes I get SMS saying that someone tried to contact me, so it is not obvious that the phone hibernated.
I was not able to reproduce the problem on the other sim card put in s21ultra (the carrier is different). I was not able to reproduce the problem on the other phone and the sim card from taken from s21ultra. In my opinion it is related to "weak" mobile signal and kind of "sensitivity" of s21ultra to low signal quality.
I reported the problem to my mobile network provider, but I'm still waiting for the answer. Anyway, I'm going to do the following:
- ask for sim card replacement (cheapest option),
- (if above does not help) go to samsung service and ask to check the phone - I hope they have some diagnostics tools,
- (if above does not help) install the second sim card (from different provider) and configure redirection of calls in case of "user unavailable" - I know it is "stupid" solution - but at least one of the carrier should work
- optionally root the phone - Can anyone confirm if it may help? At least I could enable toggling airplane mode each minute
