[Q] Random call dropping?

Hi guys,
Right, so I've noticed that when making calls with the Sensation, if they are reaching the 10 minute mark, for absolutely no reason whatsoever the line will just go silent, before the call is dropped. The signal bar doesn't even change.
Has anyone else had this issue?
Cheers,
James

My phone also has dropped calls randomly but on random times I'm sure. Today it did it as well. I don't know why though. I hope to God its not a fault in the phone that can't be fixed with an update. I'd hate switching to s-on and stock recovery.

random call dropping
Hi,
A complete n00b when it comes to Android and first post on this forum. Kindly excuse any inadvertant mistakes.
Thanks to the wonderful forum we have here, I managed to root and get the IC 2.5.3 ROM on my Sensation. And its working like a dream except for one small problem. Big problem really.
Calls keeps dropping, and there have been occassions where I was getting disconnected every 10 seconds. Patterns I noticed :-
1. Voice suddently drops. The call is still on and in about 3-5 seconds call gets disconnected.
2. This happens only in a wi-fi zone (mostly at home). When I am in a wi-fi off zone, this has never happened.
3. This was happening even BEFORE I flashed the custom ROM, (was hoping that the problem would be resolved), but no luck)
4. I suspect its because of an incompatible radio image in my country (India), but what do I know. Could a 4G enabled handset encounter such problems on a 3G network?
5. How can I get to know the best/most compatible radio image for my ROM . ( I searched, but nothing conclusive so far anywhere. I am not able to post in the developer thread because I am newbie )
Please help.

[Q] No In call Volume on Samsung Galaxy s2 Skyrocket i727 (AT&T)

I have a galaxy s2 skyrocket, and i've been tinkering around with it a lot, and actually bricked my phone once by loading an ics kernel that totally locked my phone, luckily i was under warranty, and att replaced it for about 12 dollars (shipping).
I am now running cyanogenmod 7.2, with this kernel http://forum.xda-developers.com/showthread.php?t=1398512
I originally had a problem with auto rotate but that kernel fixed that. I Had a problem with in call volume and it drives me nuts. i can make and receive calls, but i can't hear the other person and the other person cant here me, so i assume its not the service, it must be the rom? HOW CAN I HAVE A PHONE THAT CAN'T MAKE CALLS?? i am about to pull out my hair, truely i appriciate any posts. thanks in advance

For skyrocket the cm7 is little buggy. SO you need to have GPS on all the time, this will get you in call voice back. Just enable GPS and reboot your phone and you will be good. And next time make sure you post ur questions in Skyrocket Forum. Over there you will see quick response.

[Q] CyanoTouchWiz Rocket No Call Volume

I'm running the CyanoTouchWiz ROM for my Rogers S2 LTE
which is probably one of the best for this phone right now
The ROM thread said it worked for both the Rogers (I727R) and AT&T (I727)
About a day into having this ROM running my call volume dropped out
In call volume was at max, but still no sound
Everything else worked fine. Not listed in bugs for ROM
Any suggestions of fix?
Reflash?
Try a different ROM?

known issue - dont turn off GPS, and if it happens you have to reflash the rom

So what you're saying is every time I turn off the GPS this will happen?
And i'll have to reflash?

Yes! it even states to leave the GPS on

Proper Radio/Modem flashing?

Hello, I am hoping someone can set me straight on the flashing of modems/radios and what is the proper way to do it.
Do they have to be flashed during the rom flash and then never touched until the next rom flash or can they just be flashed any old time?
The reason I ask is because I was booting into CWM and flashing each Modem/Radio one at a time and testing them out. I narrowed it down to one that had the best call quality but after flashing back to it the quality was worse then it was the first time I had flashed that one. Is it possible for a modem to install differently the second time? I am not running any formatting or clearing anything.
Why would the same modem/radio give different call quality on different installs?? Should I only be installing the modems/radios at the beginning when I first flash the rom?
Would like to sort this out as my outgoing call quality is pretty bad. Tested my SIM card in my old Galaxy S on CM9 and it sounded a million times better. My Galaxy S2 LTE is on SKY ICS 4.2F6.

You can flash a new radio/kernel on your phone any time after you've flashed the rom (as roms usually flash a radio/kernal when you flash the base) and it should not have any adverse effects on your phone (unless the kernel/radio is buggy/bad for your phone).
As far as formatting/clearing, I habitually clear my cache whenever I update anything on my phone and I haven't had any issues with deteriorating call quality and the like.

That is strange. My outgoing call quality is so bad compared to my Galaxy S on CM9.
I just flashed my phone to CM9 RC2 and will see how that goes. Now I just have to wait for a friend to give me a hand testing call quality.
It's really strange how I had different results with the same radio but different installs.

I'm actually running CM9 RC2 as well and am having major issues with the radio that gets flashed with it (UCLF6) as I live in a test LTE area. The reception goes to 0 to full every 2 seconds and I never get any phone calls or missed calls when people call me.
CM9 RC2 seems to have an issue with the LTE toggle, Network Mode and "2G only" features. As soon as u turn it on, it auto switches back to the default LTE being on.
I did a little bit of research and found that I would need to flash a "RAT UNLOCKED" radio. My concern is the same as the OP in that I'm a little confused as to the proper method and steps to doing this. Any help is greatly appreciated. I think both me and the OP will benefit.
I've attached a screenshot of my about phone page.
Thanks!

I recall seeing those "RAT Unlocked" radios listed on Mohan's Embryo thread.
It can be seen here: http://forum.xda-developers.com/showthread.php?t=1754473
I have no idea if those radios can be used with CM9 or not but I'm thinking of trying the embryo ROM and seeing how my call quality goes.
My problem is nowhere near as severe as yours. I get decent signal and can receive calls fine. My outgoing audio just sounds horrible and garbled. Who knows, maybe my issues also has something to do with LTE.

That as almost correct. ROMs usually contain a kernel and the /system. They almost never contain a radio. That being said, yes, you can flash a new radio at any time. There are quite a number of radios for the Skyrocket because each ICS leak pretty much had a new one. You should have no issues flashing either a Rogers or AT&T radio on a Skyrocket. From what I've read and seen, different areas of the country do better on different radios. I would personally start with the radio from either the AT&T or Rogers official release and then work backwards from there.

The radios should work the same regardless of the ROM.

okay that sounds promising. to flash a radio do you simply flash the zip over everything on CWM? do u need to clear or format anything? once you flash do you need to change any APN settings or anything? sorry if these questions seem novice but i usually just use the stock radio. fist time doin this
Also: Where can i find and download the official rogers modems?

HMM.. Any idea why I would be experiencing these problems then? Just seems strange that I installed the same radio twice and it had different results on each install. Do you think it could be a phone hardware issue?
Would it matter if my phone is a Rogers and I am running an AT&T radio? Maybe I should try the Rogers radios?
@Ompalompa287
From what I gather... Just flashing the zip in CWM is all you need to do. No settings to change or anything. I have heard of some people wiping cache as well.

I just simply need to know if there is anyway to disable 3g (force to edge) network? I have a at&t Skyrocket running cm9 Chopsticks.

So I just found out my phone has Noise Cancellation for the microphone. Maybe it's the noise cancellation mic that is causing the issues.
Does anyone know how I can disable the noise cancellation to test this theory?

Trust me, I have looked everywhere for an option to turn it off and I can't find one. I am on Sky ICS 4.2F6
Where do you go to turn yours on and off?

since cwm does not wipe the radio, flash new radio two times, even three times just to make sure it completely overwrites the old one you are replacing

If it's in the usual ics location it will be in the in call menu.

It's definitely not in there. Strange, I wonder why it was removed from SKY ICS.

Weird Issue Call Drop using custom ROMS In the Middle of Conversation

I have the strangest issue. I get disconnected from calls in the middle of conversation if I'm using any of these main custom ROMs.
Blaz3r
CyanogenMod 10
Blaze Tweaked ICS 2.2
But If I'm using a stock ICS ROM or "Android ICS 4.0.4 UVLH5 (Posted by tthaz777)" everything is very stable and no disconnects.
I have full bar with all the ROMs and get perfect data speed and everything else works fine. I'm using the same exact apps on the ROMs as I do on the stock, so I don't think it's related to a particular app. It seems as if TMobile scans the sessions at their network level and disconnects the call because my connection is not providing some information/call data they need. The disconnect can happen as fast as a few seconds or after a 10 minutes or so, just random.
Is anyone else experiencing this ?
I'm currently running below and everything is stable with no drop calls. Just can't figure out why this happens when install any other ROM. and Yes I always to do a full wipe before install.
Android ICS 4.0.4 UVLH5 (Posted by tthaz777) with merwin's scorched-kernel-t769-ics v1.0.29

Well the 4.0.4 thazz build should be pretty stable as its essentially stock. That being said my wife (who is INCREDIBLY picky on how her phone functions... I've yet to get her to try something not TW-based) has been using Tweaked since before it was even posted and uses her phone as a phone constantly (... lot's of out-of-state sisters that she's always yapping with) and has yet to report an issue. I am unclear why you would be having these issues with the particular specificity you are experiencing... especially if kernels are remaining consistent across TW-based builds anyway. Without me being able to recreate it on my end or a logcat taken during the premature disconnect on your end I'm at a loss. If nothing else, at least you found something that works for you, so I suppose it a could be worse.
Sorry for the troubles.

Not all stock apps or play store apps work with 4.1, I had the same problem when I let my battery app manage my data. It would wait to connect sometimes up to 20-30 secs later after waking to make a call. Check all your apps your using for compatibility, and when you wake your phone give it a sec before calling out. If your in a bad area the alternating of edge/3g/HSDPA+ doesn't help either. I stopped allowing my battery app data control and that solved 90% of my issues, sometimes it still does it but only when I'm in the boonies.

LOL I am using T-Mobile service with this device, so if that's the case for you I would expect a few drops from time to time
On a serious note, drops can happen with full bars for a variety of reasons. Tower is overloaded (signal shows strong but can't connect/gets dropped), person you have called drops you (calling someone in NY that has AT&T? ), bad/faulty sim card (free to get checked and replaced), etc. No cell phone/ROM is drop call immune, even stock (and yes even those people using Verizon). FWIW, I haven't dropped a single call in over a month using Thomas' PA and Tweaked. That's pretty good considering that's including the holidays and I didn't go home this year.

Thanks for the replies guys. What drives me crazy is that I have absolutely no dropped calls when using the stock ICS ROM, but as soon as I load any of the ICS ROMs mentioned the voice call gets disconnected periodically. Same Location, Same Apps, Same Calling Number, nothing changes except the ROM.
I'm fairly technical and good at troubleshooting but not an expert in reading the Android Logcat and don't know what to look for in the log. I have loaded the UVLH5 radio after flashing the the custom ROMs to see if that might be the cause but same thing.... I wondering if I need to try an older Radio...
Like I said all is running great with Android ICS 4.0.4 UVLH5 (by tthaz777) + merwin's scorched-kernel-t769-ics v1.0.29 OC to 1728 but not knowing what's causing the drops is just driving me crazy....
To test I just load the ROM and then call one of the free news numbers (ABC News etc 650-293-9114) and put the phone on speakerphone, and yes I have tried varies other numbers... JUST WEIRD

Try finding an app of the app store to make logging easier like logcat or something. Then run the app and make a call. If it doesnt disconnect, restart the log. When it does disconnect, end the log and copy+paste it here. That is the only real way to find out whats up.

So the problem started again this AM and it's been fine since I flashed Android ICS 4.0.4 UVLH5 (by tthaz777). I hear the hang up tone and calls would just disconnect in the middle of conversation with perfect signal strength. Nothing new was added to the phone, so only way to fix it was to reflash it again from a nan backup.
This is driving me crazy. Attached is a short logcat from right before the call dropped, could one of you experts check it out and tell me if you see anything strange going on....
Thanks

any chance you can put that on pastebin instead of a pdf? just post a link to it. It could be helpful to a dev as I see that some info is spread out to different pages and is cut off.
Also did you use an existing sim from a previous phone when getting this phone or did you get a brand new sim? I know various issues arise when using an old sim with this phone. My old sim had issues and wouldn't connect to wifi calling and it was only 10 months old.

When I initially had the issue I ordered a new sim hoping it would resolved it and that didn't help, so I flashed ICS 4.0.4 UVLH5 (by tthaz777) which is pretty much the stock with bloatware removed and that resolved the problem and not a single dropped call for a month and it just started again. It's so weird as if Mobile is looking for something in the connection/session and forces a disconnect.

Ordering a new sim doesn't mean getting a compatible sim. Have you taken the phone to a Tmo store and had someone check it out? They could've sent you another partially compatible sim for it. If I knew more about reading the logs I would love to help you out....
