Longtime Sammy ROM (mostly Wanamlite) user here, dabbling now with new 4.3 ROMs based on AOSP, namely Carbon and PA. I like both of these releases and for the most part few problems but one:
The precise moment I start a cellular call, my mobile data connection drops. 3G, H, H+, doesn't matter. As soon as the call is over, the mobile data connection immediately resumes. Sorry if this is a noob question, but am I missing something here? I've played with a number of ro.ril build.prop settings, none of them seemed to influence this behavior a bit.
This is a deal killer for me, I commonly run IM clients and participate in web data conferences while simultaneously making phone calls. This works against AT&T service on the Sammy ROM.

Are you sure you have the GT-i9300 on AT&T and NOT the AT&T version?
I too am on att and use an i9300 not sure but i think the att version would say 4g instead of h+ or 3g. anyway What I do is I always use Stock rooted roms. I alter the default apn to geta much better signal. att does not recognize the I9300 as an sgs3. they frankly do not know what it is . also they do not support it. so they put the phone in the wap cingular default apn. this is also used for their prepaid and dumbphone customers. you can manually change apn settings.to get better data speeds and signal.
I have been researching on this for a few days. It seems like it is a motherboard issue with several GS3s... This sounds stupid, but try to hit the back of your phone really hard.. If the sound is workign for five minutes after doing this, it's most likely a hardware issue, just like mine..
i would think that hitting the back of the phone really hard would most likely cause damage to the motherboard and other microelectronic components. the op has stated that he has problems with his signal while using aosp roms. but the problems disappear on sammy roms. that would indicate that his problem is Not hardware related rather than software or incorrect settings in build prop.
I do believe you when you say you have hardware problems. if you are hitting the back of your phone as you have recommended to the op. it is almost a certainty that you have damaged the fragile internal mechanisms inside your phone.
Yeah! But the problem is that this is a known hardware problem with the S3. It's very annoying cause I love my S3.. Would be a bummer to sell my iphone 5 just to get a new S3.. I was thinking of buying a motherboard and install it myself. I just hope that the fault lies within the motherboard components
well first you need to find out if the problem is hardware related. my suggestion is to get your phone back to stock if it isn't already. then see if you have the same problem. if yes then try factory reset . if that does not work then you probably do have a hardware problem . but it is probably your baseband or antenna rather than your motherboard, also check that your apn settings are correct,
if you decide to send it to a service center do not tell them that you have been hitting your phone, and please don't advise anyone to hit their phone either, these devices are not cheap and hitting them will cause physical damage which is not covered under warranty.
Sure I understand that advicing someone to hit their phone is stupid. But taking from my example I've tried a bunch of ROMs, a bunch of radios. I've also reverted to stock ROM with the same problem.. the audio comes and goes when knocking the phone behind.. I've also tried to reassemble the whole phone myself. I've reattached every wire there is and the problem still persists.. This is a very weird problem
definitely sounds like hardware problem either speaker or wire connection.if the phone is under warranty then send it to samsung. if not then find a reputable repair shop that understands how to fix it. shop around because too many places only know I phones. also you can go for a paid repair from samsung. may cost more but at least you know it will be fixed right.
Thanks all for the replies. First, I have no plans to hit my phone nor do I have the audio issues the other poster hijacked regarding

Worth noting, I do not have LTE enabled on my AT&T plan (I have a grandfathered unlimited iPhone data plan) so can't use the lte or other "4G" APNs out there. I tend to use the wap.cingular APN as none of the other posted alternatives work better (or at all). What APN do you use out of curiosity?
Since my OP, I've also tried SuperNexus 3.0, and saw precisely the same issue. I've fiddled with bringing in applicable ro.ril build.prop settings from Wanamlite's ROM, checked my modem (it's the same between Wanamlite and the AOSP ROM's I've tried, I9300XXEMB6), tried different APN's nothing seems to work.
One thing I haven't tried, is to use a well-established AOSP 4.1 or 4.2 ROM.. may do that later if no other bright ideas come along.
att apn settings
this is what I use. just one apn called PHONE . I am in new York city. I don't know if this will work for you where you are. I am rooted and everything else is stock

I had this problem running miui, cm7, and now I'm on unnammed. I've used all the modems and still nothing helps. I thought unnammed didn't have this problem? To fix it I haft to flip to airplane mode and back, then its fixed.
Sorry if this has been asked. I'm on taptalk on my phone and I don't know how to search with it

Could be APN settings. I don't know them off hand, but they are listed in post 2 of the miui thread.
If it happens on multiple ROMs it could also be a bad SIM card. Does it do it on pure stock? If so, try a new SIM card.

This. I haven't seen this issue reported often, and in the past, it's turned out to be an app interfering with the connection. If not, it's likely an apn issue.

I've had the same thing happen to me on other AOSP roms too. On both the SGS2 and my captivate.
I just switched to iscrewed to see if the prob is still there. Its hard to reproduce the bug, but it happens when i go from either:
1. being connected to wifi for a long time and then leaving that area, mobile data doesnt turn back on
2. being in a bad service area for a long time, and then leaving it, mobile data doesnt turn back on.
The worst thing about it is i use google voice for texts, and thats usually how i can tell that it cut out, because i stop getting texts from people.
I love android and google, but honestly if problems like this dont get ironed out, then as long as the next iphone has a decent size screen im probably switching over.
FYI this has occurred when i had the bare minimum installed on my phone, and i never use any ridiculous battery saving apps.

ill try this out tomorrow. just now when checking my email i had to turn on airplane mode and back off to get data to work.
also, i tried the apn settings on the first page of the miui thread and it didnt work. i tried those settings on miui, wiui, cm7, and unnammed but they all made it so that my internet didnt work at all.
so just to clarify, i shouldnt haft to change apn settings and my phone shouldnt be doing this on non stck roms, right? sim is likely the problem? this has gotten really old really quick and its embarrassing when im trying to show my friends something but my phone isnt working.
Your phone should work fine on any ROM you find here. Mine does. I never have to play with APNs, even on miui. I never have to play with airplane mode or power cycle. But, when my SIM was bad I would drop data connectivity all the time. Calls would fail (outbound only), and other glitchy reception issues. Sometimes airplane mode fixed it, sometimes power cycle, sometimes airplane mode on, power cycle, and all times it was temporary. Its worth a try, shouldn't cost anything to get a new SIM. If they give you trouble at the store just tell them you called 611 and they told you to go in for a new one. If that doesn't fix it go warranty route for a new phone.

Those APN settings have worked fine for me on both CM7 and every Sammy ROM I've used. I always have (unrelated) problems with MIUI, so I can't verify that one.
So i went today and got a new SIM. Its been about 9 hours, but no problems yet. Time will tell if it works, but im willing to bet that was the problem, and this is why.
When i went to get my sim, the guy there told me that when ATT started rolling out 4g phones (which includes 3.5g) many employees had trouble with their data switching on and off until they switched their sim cards.
Then i started thinking to myself - I've had the problem about as long as I had my SGS2, and only had the problem with AOSP roms on my captivate - then i made the connection.
When i used a stock, or stock based rom on my captivate, i had no problems. The second i used an international ROM, or an AOSP rom is when i would have the issues. What is the difference between the roms............. The ATT rom doesnt have hspa+ enabled, so using my old "3g" sim card i was fine. No 3.5g to connect to to cause problems. CM and international Roms would use that new 3.5g network and would then screw up.
That is my theory anyway, and if it turns out true it would have solved one of my biggest annoyances with android. (or at least my android experience)
fingers crossed
i too went in and got a new sim. my phone service actually quit working before going in. id get calls and i could hear them but they couldnt hear me. i replaced the sim and all is good. where miui would hang and data would freeze and id haft to redo the airplane mode trick, it would just hang for a sec or 2 and then start downloading again. ive only had it hang 2x now and i think its because it might be switching from hspa to 3g or even wifi.
so for the sim card thing worked. if it fails in the mean time, ill come back to this and give an update. thanks for suggesting it being the sim card cause i wouldnt have thought of that.
I'm another day strong without any problems. I don't know of its due to the new sim or because i switched to a Samsung based rom. I should switch back to test, but I'm loving the speed of icsrewed right now.
If i had to guess i would say it's due to the sim, and if so, there should be a sticky somewhere that says to make sure your not using an older 3g sim card. Would have saved me months of aggravation.
Will report back after a few more days. In a week or so I'll switch back to cm to see if it fixes it there as well.
That's one reason I generally buy my phones at the att store (authorized reseller, but dedicated to att phones). Usually they will price match, and they know things like that. My SIM went bad when I had my captivate. Later when I upgraded to a faux G phone the att rep knew I would need a new SIM, and replaced it then, even though it was only a month old. They also knew the "3G" data plan needed to be converted to a "4G" (still unlimited) plan on their system for me to get data.
You don't get that kind of assistance when you buy at Walmart, online, etc.

Interesting, maybe next time if my data refuses to work I should bug at&t for a new Sim card. I had problems on different roms including stock rom where I had to turn off and on my data or else it will not work. But I think my modem might have played a role. Data seems fine now.

Yup just show up. They shouldn't charge. as long as your an att customer theyll take care of you. I've never heard of anyone paying for a new Sim. If you lose your Sim I've heard of them charging people, but i doubt they'll charge even then.
I am admittedly a noob when it comes to Android phones. I have had my i777 for a few months now and have successfully bricked it more than once. Having said that, I have found that the answers to my questions have always been on the board somewhere. I am having troubles figuring out where to go with this portion of the issue though. Having tried several different ROMs for my phone, I keep having the same issue. With any ROM, other than stock, I miss phone calls or text messages when my phone is locked and on Wi-Fi at home. If I'm out and about with my phone in my pocket and locked, it works normally. But, if I'm at home working at my desk and the phone is locked, I will not get text messages or phone calls. Notifications from apps like CNN continue, but nothing from the mobile network. I have followed the guide to return to stock and built my own jig that worked to reset my flash counter as I flashed before I read when I got the phone. (Former iPhone user that just assumed it was as easy as a jailbreak, really really dumb on my part)
I am a tech geek. I follow instructions well. I am sure the problem is with my phone and not the ROMs. My question for the forum, is where to begin troubleshooting the issue. I want to be able to use these ROMs.
Some info that may be helpful:
Baseband: I777UCKH7
Kernel: 2.6.35.7
I have tried the following in no particular order:
UCKK6-SHOstockV1.9.2noWipe
Serendipity_8.2
update-unnamed-v2.2.1-full
ICScrewD_2.1
TurkbeyRom-v33
Each has individual issues that I can deal with and learn to fix, but the phone issue I, obviously, cannot get past.

No I have not. Does the wifi connection prevent the cell network from connecting?
cell network shouldn't disconnect at all if it is, swap it out could be bad phone. Also what is your signal level at your desk at home? Low signal normally causes missing of messages.

No, it doesn't.
Do you use any 3rd party apps like tasker?
When did this issue start? Perhaps there is an issue with the tower that serves your home. How strong is your cellular signal at home? I believe text messages (except MMS) are sent over the cellular network. Your being on wifi shouldn't matter (does being at home with wifi off and the phone locked still cause issues?).
I can't imagine other ROMs causing issues, though. If anything, they would mess up your data network only if they had the wrong APN settings for your area (for example, for a while, people using Unnamed didn't have data issues, except for a few like me who lived in certain areas with Cingular towers). Or maybe the stock modem files are better for you than the ones provided by the ROMs?
Maybe you have an old sim card that somehow has issues? You should be able to get a free one from at&t. Do you have another phone that you can test it with?

I keep a minimum of 3 bars and live near the center of a large city. As stated in the op, this is only happening on added ROMs never on stock. I have again reverted to stock (+root), since the op, and confirm that I am getting messages and calls at my desk at home with the phone locked.
****************************Edit for SoCaliTrojan post********************************************
I do not have any additional task managers installed, I've just always used the one built in. As for the SIM card, I am using the one that I got with the i777 at upgrade and get the 4G network when not on wifi, so I think I can rule it out. My wife has a Note that I have been drooling over, guess I will have to "borrow" it for "testing" when she gets home from work.
Also, I notice I am on baseband KH7 with Android version 2.3.4. I see mention of KK6 and 2.3.6 on the forums. I have avoided flashing the baseband, when possible, to keep from possibly bricking the unit. Is it possible that upgrading these could resolve the issue?
That is a very weird problem. Only thing I can suggest is compare the APN settings in root with a custom rom's settings. They should be identical, but check anyway.

Then it isn't connecting to 4G networks.
It's labeled as "4g" but really just multiple 3g connections to give you a faster overall speed. But you might want to just try getting a new sim card at your AT&T store, if that doesn't work, try a different modem (like KK6) the whole list/downloads are in the development section.

I made AT&T upgrade me to a n LTE sim card. Our phone disent have LTE but the newer sim cards supposedly will make your speeds faster when LTE does come to your area due to it pushing HSPA+ faster than enhanced backhaul.
You said you live in the center of a big city maybe being surrounded by a lot of tall buildings could be causing havoc on your cell reception.I know at my work I can send and receive messages and calls everywhere except our breakroom but everyone else's phone works fine in the breakroom.

Hello All,
I have been looking around and seeing if anyone else is experiencing the same issue I have. But I have not had much luck. I have seen similar cases, but for whatever reason, some of the workarounds found that worked for others have not been successful for myself, or are temporary.
For the past three months, I have been experiencing an off and on issue where I am unable to receive texts, but I am able to send out text. And it is something that I would not realize until people actually notify me, or it is awkwardly silent on the "texting front", which makes me second guess myself. Almost every other week or two weeks this has occurred. At the time, I am running Darky's 8.8 [4.1.2] ROM for the i9300. I have tried rebooting, taking out the SIM, re-flashing Darky and re-flashing Stock (full wipe, etc), and replacing my old SIM with a new one. None have been successful thus far. The only success I have found is that inserting my SIM in a different phones allows the text to flow through almost immediately. I would then place the SIM back in the i9300 and any new texts sent I would receive immediately. After a week or two, it randomly just stops receiving text again, and the cycle continues.
I was wondering if whether this may be a bug with the Android OS itself? I have seen a few posts in regards to SMS being handled by Jelly Bean, but I am not 100% sure if my issue would fall in the same boat. Or if it is possibly faulty hardware? Or some kind of network issue. My network is AT&T, but I'm ruling out a network issue since I am able to receive text almost instantaneously on other phones.
Any information, advice, or help would be greatly appreciated.
Its not a bug .
Usual reason is wrong MMS message centre settings or network settings .

I've verified that the MMS APNs and SMS settings are correctly configured to AT&Ts network. If it were incorrect from the beginning, I would not get text messages (or MMS) at all. But in this case, it is intermittent and only resolved when I get to "unload" the text messages on to another device.
Same thing happens to me (why I had to use my upgrade to buy a phone from them -_-) I'm using a S2 for now... it sucks when you have been on the S3. Their excuse for not being able to help me was "Its an international phone, therefore may not work with our network." That's freaking BS. It worked for 6 months before this issue came up. New micro SIM card is the only temporary solution for now. When I have time. I'm going up there or calling help line. Gonna file a complaint and mention I might be leaving service with them or I can say legal action will be taken since they are denying me a service I'm paying for. They should start helping by them. I don't abuse their services. I don't tether. I don't cheat them in any way. Its retaarded.

Ahh! Thank you b-eock! I don't mean this in the wrong way, but I'm glad that I'm not the only who has experienced this. When this occurred to you, were you on some version of 4.1.2? From what I can remember, this issue never came up until I upgraded from 4.1.1 to 4.1.2. Just trying to find some kind of trend here...
I have had to call up AT&T a number of times regarding this issue. And each time they were of no help. Although they were able to confirm that everything on their end of setup correctly, I got the same BS that you got. And they even gave me the whole baloney that I should upgrade so that they can help assist me better and that since it is not their branded phone, it may not be fully compatible.
I really do not want to give up on this. And I definitely want to find a solution. So I am hoping there is a lucky one out there that has tried different ways of getting fixed. Whether that be trying a new ROM, or downgrading from Jelly Bean to ICS, etc.
Came up a few weeks after I upgraded to 4.1.2 but there isn't really a connection between that. It worked before. Its just random crap. And them telling us everything is good on their end, that's complete BS. They don't know what's going on behind their computer screen.
Same exact thing happens to me. It's ROM dependent i'm thinking. Samsung roms from other countries do it the most for me. Has done it on AT&T and AT&T with StraightTalk. Experiencing it on Purelok HD v3.1 right now. I love this rom but im probably going to go AOSP/AOKP as I don't experience it on those kind of roms.
Camera just isn't the same without the Samsung software to me.
Ok, I've had issues with this phone that began with a bad battery. I got a new battery through insurance and my problems continued, even worsened. The phone will lose network connection constantly. It will reboot on it's own or during use. This is the only way it will obtain network connection once lost.... I went to at&t a million times and they flashed it for me a few times, replaced my SIM card three timesthis month and no luck. I decided to be brave and root it with cyanogenmods latest 4.4.2 kitkat (which I love, props to them) and it still continues to do the same crap! It's getting old and im beginning to think it must be a hardware issue, but I read about flashing a modem for the phone. Does anyone know if this might solve the problem or is it likely a hardware malfunction?
It seems to cause the most issues when im not on wifi or when LTE is activated.
Tried the *#*#4636#*#* code to change the connectivity settings but the only option im allowed to use is the lte/gsm auto (PRL).
Any advice is appreciated.... my next option is shooting it with my shotgun and using it as a conversational piece at the office.... maybe a

I decided to be brave and root it with cyanogenmods latest 4.4.2 kitkat (which I love, props to them) and it still continues to do the same crap! It's getting old and im beginning to think it must be a hardware issue, but I read about flashing a modem for the phone. Does anyone know if this might solve the problem or is it likely a hardware malfunction?
It seems to cause the most issues when im not on wifi or when LTE is activated.
Tried the *#*#4636#*#* code to change the connectivity settings but the only option im allowed to use is the lte/gsm auto (PRL).
Any advice is appreciated.... my next option is shooting it with my shotgun and using it as a conversational piece at the office.... maybe a
A paperweight??
thank you for your time.

Could be a modem issue, could be as simple as changing you APN settings. Where is your location? Could be affecting you a bit. Run a search, many have had this issue.

Ok, I've had issues with this phone that began with a bad battery. I got a new battery through insurance and my problems continued, even worsened. The phone will lose network connection constantly.

I live in central Arkansas and I'm not exactly sure how to check my APN settings...?? And if it's a common issue based on location, why does AT&T not recommend a solution to anyone with problems? Or do they and I just don't know?
I've ran this phone on straightalk 3g for about a year. Recently upgtaded to a lte sim and loose signal a lot since. Miss calls. Don't get text. I have read certain art lte towers have this problem. Sounds good since my wife's s4 has same problem. Both phones ran fine and got calls on 3g sims

I found the settings directly through the AT&T website but theyb only povide 4G HSPA+ settings.. which are not LTE.
Follow this steps and check if your APN settings match, and if they don't then just create a new profile with the settings in this link:
http://forums.androidcentral.com/go...ogle-nexus-5-t-lte-apns-network-settings.html
Techinically, this settings are stated to be for the Nexus 5, but the APN are carrier based, so regardless if it states Nexus 5 APN settings they would still work for our OG Note
You should be able to get to your settings by going to settings / wireless data & networks ---more / mobile networks --- Access Point Names
Hope this helps!
Hi, I am new to Sony family and bought used III which mightve been a Mistake.
I never see the signal having all bars full. It also reports values around 100dbm.
I have not been making calls really but I can see the reception is worse than with my old Xiaomi 9, same for 4g. Sometimes it drops and only restart fixes it.
Running dualsim, different carriers. Did network config restarts etc.
Lets assume it is sw problem. Could it be bad non-eu stock rom? How do I check?
I might immediatelly go with custom rom, maybe on android 12 just to see if it works better. Any suggestions? I just dont think factory reset or flashing stock is gonna fix it easily and I am open to experiments as long as the system and mainly signal reception is stable because next stop is trashbin really. The phone is overall great, I just did not expect phones having such problems nowadays.
I've seen the same, especially if I go underground for a few minutes - the phone can't reconnect unless I restart it or switch on and off the airplane mode.
But apart from that I have a pretty stable connection, no matter what the bars show.
My uneducated guess is power savings affect the signal strenght.
Never had problems during calls, no matter if driving or stationary

As A current Metro by T-mobile sales rep, and self proclaimed cell phone guru, some carriers require a phone to be registered on your account for it to fully work, even if the phone on paper has all the supported bands of said carrier. so this could be the problem, and if it's a software problem you can simply reinstall the correct firmware for your region and device and see if that fixes the issue, you could also try a different region but same device model number...

I have not really tested it much in such environment like underground. The signal mostly stays ok, not full at all but the connection works tho. I had only like 2-3 restarts/week due to connection reporting only EDGE available (still I couldnt browse anything) and both sim signals showed a problem (exlamation mark), I think it could have been caused by worse reception conditions and it eventually stopped working at all.

I dont see registration being a requirement here in EU. These are prepaid simcards, no binding to a device, no contract and such.
I dont know if its software problem. After little bit of Googling I came to a conclusion that Sony does indeed have problem with signal reception no matter what is the cause. To me it seems it could be SW related. Question is if flashing stock rom is the way to go or maybe using a custom rom as daily driver?

What os/rom do you have? Have you had any success on making the reception better, more stable? Did custom rom help with that anyhow?

In the states Metro by T-Mobile is a prepaid company that uses T-Mobile's network, but they specifically require your current device to be on your account to make sure they can give you the correct info on why your phone isn't working correctly. And some times to send the correct configuration file to your device. But in your specific case i would say go the firmware route and see if that fixes it before calling the carrier to see if there's a config file or something similar they need to send.

Thanks for the explanation. I chose the FW route, testing AlphaDroid as of now. So far so good. Reception already looks better so I will stick to this rom for now and see how it performs.

Just a tip, you might wanna force 4G even on custom ROMs, I am running same config as you double sim and diff carriers but i get better result by forcing LTE Only on my main data SIM.

I have a quick update for you regarding my devices connectivity problems
I reflashed the latest global firmware, this overrides the modem 5g configs that you find on all of the 5g enabling guides.
immediately my reception AND my phone switching between 3G, 4g 4g+ etc was better. Im not saying im magically getting full bars, but its improved substantially on top of switching between networks when travelling etc is instantly now. Instead of me having to enable flight mode to reset my network every time.
i will try flash a custom rom and see if the reception stays fine
only had problems after trying to enable 5g and follow the guides.

Cool, thanks for the info. What is the version of that global fw?
I had only one network disconnect on AlphaDroid but it managed to fix itself within minutes. Still the display seems bit irresponsive to touches at times, baterry drain is not the best and also call quality does not seem to be the best. So I am considering switching to global or maybe different custom. Ofc it could be just my device.

You should start using 120Hz if it feels slow (go into QS settings and get the refresh rate toggle from there), also enable High polling rate from Settings > Display for better responsiveness, also if you're rooted/using Shizuku you should try https://github.com/kyujin-cho/pixel-volte-patch/releases it may unlock some SIM options that may improve your call quality.

6.1.2.A.0.447 was what I upgraded too
Honestly, I don’t have a single practical use case for my phone where i need 5g enabled, so it’s really not a deal breaker for me to not have that enabled. 4g+ is still pretty quick especially for my use case. If you want volte & vowifi I recommend magisk + zygisk so you can use banking apps. Works well for me and call quality is fantastic
edit: I think I should note i did a full clean flash, flashing all and wiping all data on the phone. It’s been a few days and signal noticeably better.
edit 2: spelling (damn autocorrect)
