I've seen this issue come up several times lately. Unfortunately I don't know the cause or have a solution, but I do want to see if we can figure it out together.
I tend to have very good luck with calls and signal holding on the 2.X ROMs. I've dropped a couple calls over the last few months, but that's generally signal related.
One thing I suspect, but have yet to confirm, is that either ActiveSync or other network app is trying to create a data connection and the phone is obliging, knocking down the voice call as a result. It *shouldn't* behave that way, so I'm just guessing based on a few quick observations, but it might be something to look into. I don't know how much control the OS can give to apps when it comes to forcing a data connection at the expense of voice (should probably be none), but maybe there's some badly behaved apps out there.
I'm just throwing ideas out so we can work towards a solution.
EDIT:
I should probably clarify that I'm talking about a problem of dropped calls happening at seemingly regular intervals, not dropped calls due to poor signal strength.
I have to completly agree...my favorite rom was on of the first summy rommy's but as always i kept going to the newer ones as i have no self control. I was getting a ton of dropped calls I thought i was hiitting the end button with my cheek it was so bad. I have been running the new dopod 2.21.13.1 WWE and it has been flawless, it get about 28 mg of program after clean install. I have had just about every damn rom on my phone and this works well. I don't do the extended rom, i just use a autorun i made with all my apps i normally use, maybe give it a try, it could also be dumb luck, but i have yet to have a single dropped call, and i do sales in Las Vegas to the hotels and I get reception in elevators and in basements I never used to. You are the expert, let me know. ****Warning this post is 100% personal experiince, and absolutly no expertise except experience screwing up my device and late nights running stupid benchmarks for hours to see if I can get it a wee bit faster. Stafford out
well i'll say this, everytime it happened, it lokked like it was going into flight mode each time, then going out and back to normal a few seconds or so later. i flashed with the cooked a2dp rom, and left everything stock, it hasn't happened since.
I haven't seen it at all on the stock Qtek AKU2 rom. It seems odd that a re-flashing process seems to correct this since the base rom is the same. You'd think customizations may be the underlying cause but then everybody should be experiencing the issue.
i was having the same issue too, so i was thinking maybe it was the radio rom. i downgraded the radio rom to 1.13 and i've been testing it out so far. The last two days i've been okay with no dropped calls though i have not made any very long calls yet to fully test it out. i will keep u guys posted.
Well Summiter, for what its worth, I have an 8125 and I'm running that Cingular_RUU_WIZARD_217_AKU2_WWE.exe ROM you released. Radio version 2.07.10.
My results have been absolutely phenomenal. Not only is the device rock solid at clock speeds in excess of 270 MHz, but the battery lasts incredibly long and I have had zero dropped calls in over 2 weeks of use within a 50 mile radius.
Even though this ROM doesn't have your A2DP cab I quite frankly don't care, I'm going to have to think long and hard before I use any other ROM version, official or not.
Edit: I should also note that I'm using Direct Push which means I'm on a constant EDGE/GPRS connection. Even though I've been running this for around a week now, it has had no noticeable effects on my ability to receive or make phone calls. My sole issue with Direct Push was a lockup that would occur when I enabled WiFi, but changing the WiFi registry key "ResetOnResume" to 0 has fixed this.
just an update. i downgraded to 1.13 radio rom and direct push and all calls are fine now. I think i will leave it with this radio since everything is working great now.
Happened during Active Sync
Saw it with my own eyes! On the phone with our PM through BT800 this afternoon and was looking at the screen when Active Sync kicked in and the call immediately droped. (But I did get an email for a good price on Viagara!)
Running: MSVC, SPB Pocket Plus & push email from Exchange
For those folks that changed to a 1.X radio version, I'd like to know if your issue has been completely resolved, or if it's only improved to some degree.
I think the AS activity when a call drops may be because it opens a data connection the millisecond the radio has closed voice (when dropped for other reasons). In other words, the appearance of AS or other data activity actually forcing the voice call to drop is misleading.
If I experienced dropped calls on any significant basis I'd test more of this myself...but (un)fortunately I don't drop calls more than once a week, if that. So..I have to depend on you poor saps who can't hold a voice call to attempt to resolve. >: )
i thought it had resolved completely but i had my first dropped call last night with the same problem looking down and seeing that it dropped the call...tried to establish gprs(edge) and then went in and out of flight mode. the 1.3 seemed to have fixed it a little but not completely. with the new radio i was dropping calls within 4 mins of a call. with the new radio rom i have the only one dropped call 45 min into my call. I probably would have dropped 3 or 4 times before. I don't know what else to do to fix it.
What ROM version and radio version are the people with this problem running exactly? I think that's a good start maybe to get a scope for the issue.
I'm using "Cingular_RUU_WIZARD_217_AKU2_WWE_CF2_A2DP-fixed.exe" and have experienced many dropped calls immediately followed by no signal (searching for signal) for about a minute after dropping the call.
ROM Version
I'm using the Cingular_RUU_WIZARD_217_AKU2_WWE_CF2_A2DP.exe ROM
I'll try some tests tonight to duplicate what happened yesterday.
Another bit of information that could be helpful is whether or not you are using handsfree when your calls are dropped. This is especially important if you are using the A2DP hack or a ROM integrated with A2DP.
Clueless
Don’t know what the h*** happened yesterday. (maybe I’m seeing things….or the “flight-mode” hiccupped?)
Called to & from the phone with & w/o hands free while sending myself emails. No failures…why?? Because GPRS is suspended during phone calls. I’m sure there is a reg hack to enable GPRS during a call.

I should note that this has occurred while on a bluetooth headset (not stereo) and also when not on the headset.
I'm using Cingular 2.26 Aku2.3 w/a2dp FULLY LOADED *BETA* **UPDATED**
I get dropped calls using a bt headset, a wired headset or no hands-free at all.
Appears to go into flight mode and back out when it occurs. I have noticed that activsync runs all on its own (i haven't synched with a pc even once)
I've had the issue on every rom i've tried recently although i don't remember what they were.
I have a question....my handset not only drops the call it soft resets about 5 mins into the call. POOF! IT is CRAZY!
Anyone having that issue?
On edit for more detail and clarity:
It even happened after I did the HTC GPRS workaround. It didn't stop until I disabled data and activesync through the comm manager
I am not having that issue now. I'm on a new rom.
My stock 8125 will do a reset, but it isn't with every call. I think I've only seen this when using hands free. I'm here looking for an updated rom to get rid of this "feature" of dropped calls and resets. Its driving me up the wall.
And yes for the basic dropped call, mine seems to go into flight mode when this happens, and yes, I see ActiveSync then running on my phone when I wasn't connected to a PC at all that day. The dropped calls happen whether I'm hands free (non stereo BT headset), or just using the phone handset itself.
This is my main frustration with this phone right now. Microsoft Voice Command (new 1.6 with BT support) fixed my other complaint in making the phone easier to use as a phone.

I have noticed that ActiveStink is in my tasks as a running program when I'm not connected to my PC. I think though it is because I have an exchange server. I wonder if connecting to the exchange server is what is causing the call drops?
My g1 have big problem, it loss signal all day, most the time. I tried turn on air plane mode and turn off, or retart the phone, wipe, up another rom, up newest radio version, use 2g network only. But it doesn't work.
It loss signal random, i can't control or do something to have signal again. even i change many other sim cards. but i discover one thing: seem this problem related air plane mode. because in some rom version, i turned off air plane mode but it didnt, even i restart my phone it still on. i must take out the battery for long time and put it again.
Some time it have signal again but it only for short time.
How can i fix this problem, please help me.
please someone can help me. my phone isn't a phone anymore
hhmmm...Try to upgrade to the latest radio for g1. If that doesn't help, maybe your rom has messed up apn settings or the service in your area dropped.

I can add few things to this since I experience loss of signal multiple times every day:
I have 2 G1s. On both of them it happens:
1. Using different ROMS (CM, Super-D, OpenEclair)
2. Using different recoveries (RA 1.5.2 and 1.6.2)
3. At different times of the day
4. Using different radios (older radio and the newest one, sorry I can never remember the numbers)
5. Across different states ( I took one of them thru 5 different states and it kept loosing signal)
What happens is that I start a program that requires data (twidroid, FB, Gmail, Market) and I see my connection get stuck on the uplink, go away completely and restart the radio. Another way it will do it, is that it will stay on blank screen (or downloading screen) and there will be no uplink or downlink shown)
Tried: wiping, re-flashing radio, re-flashing rom, getting rid of few apps.
Anyone with any insight on this? I can get a log next time this happens if anyone wants to take a look.
Thank!
i tried many diferent rom, radio, and recorvery too. but it still doesn't work?
Now i discover that any connect in my g1 seem doesn't work. wifi can search but when i connected it can't open any page even google. gps can receavie signal, bluetooth can turn on but no one can see me or i can' connect to my headset bluetooth.
May i think it is mainboard's problem? i opened my g1 and see anten signal very perfect, don't have any space or something like that.
Hi!
For 3 days i have a problem with GSM signal...
It started, when during the call it just interrpupted it and went to home screen with no reason.
From this moment it's permanently looking for a signal - no resets or switching airplane mode on and off help... ;(
sometimes, outdoor, after reset it finds very good signal - max 3G and holds it until next reset... BUT... when i tried to sync weather it doesn't and gsm signal went low. aprrox 5 seconds later went to NO SERVICE...
Anyone knows it? Can You help?
Have the same issue with mine
Device just lost signal - firstly I thought it was because of poor signal quality, however the problem was still there in any conditions (outside building, etc.)
Before that, I had the same problem with Touch HD - had to replace the motherboard (luckily it had warranty) because of the faulty radio module.
Did anybody manage to solve this problem with Diamond?
Thanks!

i have the same problem hope to get it working again :-S
Hi, i have that problem a couple of weeks ago, it was very simple, the contacts of the GSM chip was dirty, y took it out, clean the chip and the contacts and never have the problem again.
Sometimes the most simple things, are the last we think.
Hope this is your problem, much easier than hardware problem.

well, my wifi is acting wierd... reception is good and it doesn't disconnect too often, theres just this little anoying thing!
everytime roughly 3-4 days after i flash a new rom my wifi simply refuses to connect to network, and not a specific one, any network at all!
and it stays like this for a couple of hours and then all of a sudden it picks up a a networks and it works fine for a while, untill i happens again...
i've tried restarting and taking out the battery and turning the wifi off for a while, nothing seems to help, he just decides on his own when he is whilling to connect again....
if i flash a brand new rom the problem disapear for a few days but then it comes back... i'm assuming it has to do with some sort of a cache that is filling up with loads of crap and ruining the wifi activity but i tried googling for this and found nothing..
ideas anyone? (btw this happens on all roms: stock, existenz, beanstalker etc...)
its a hardware problem and not so uncommon look here
http://forum.xda-developers.com/showthread.php?t=2531711
if you can take it to a customer support and if you cant sell it and again if you cant, then just get along with no wifi/bluetooth/NFC check all of them you should have problem with them too

absolutly not related, my NFC and bluetooth works just fine, i don't need to press hard anywhere...
and my wifi works just fine after a fresh rom install... so it's defenetly a software problem...

to me that sounds like the start of it because mine was the same at the first few days flashing a new rom or something would help alot but then i just found out the only thing that was helping it to get fixed was the heat from the device not the rom, but it doesnt hurt to play around with it a little so go ahead and try some other roms or repairs.
you see good reception for wifi
you try to connect
at the authorizing or connecting you will see only one point of signal and connection would kinda like disappear.
this is how it was for me but at the first days it was random it was connected good and ready, when i would left the phone in stand by after a few minutes it would DC, so i thought its kind of a sleep mode malfunction or something but after a few days almost 1-2 weeks it turned out to be hardware problem like ohers so if you see any symptom like that start looking for service centers.
but i hope it would be a software problem for you, so good luck.
Well, once he connects he stays on for days, no problem there... Just sometikes he refuses to connect... Pressing the nfc button doesnt help...

What Wi-Fi channel is your network on and have you tried 5GHz?
Didn't look into those things, but it happens with all networks except ones without passwords
Sent from my C6903 using Tapatalk
Have you tried deleting wpa_supplicant.conf in data/misc/wifi and reconnecting to the network? (this will delete all saved passwords and settings for known wi-fi networks) also try to disable Auto IP in advanced wi-fi settings
Well the phone is qith my sister now, I got a new z1 so far wifi worka for her, it stoppes for a few hours yestarday but came back, I might try to flash. 310 and see if it works better with it. And the Wapa_sup sounds like a good idea. Btw z1 is also jittering some with wifi, it's a global Sony problem...

temp solution?
Well, it is probably a hardware problem. I have had the same problem, everything looks fine, but you can't connect to any network.
So, searched, reinstalled, etcétera, nothing worked. Untill I read a crazy solution link://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/xperia-zr-wifi-association-rejected/td-p/516275/page/4
and found out that if you put pressure on the back of your pone right at the NFC chip, with a finger or so, the Wifi will come alive again.
Personally I had to hit my pone's back at that exact spot with my finger (for not damaging it with excesive force) a few times, but then suddenly it worked.
So, I am convinced it's a hardware problem. Hope it works for other people too.
I bought a LT30a over the Internet a year ago. I used it primarily as an app device and GPS, so didn't use a SIM much. But lately I have a need for a phone that works both in the US and UK, and this is it.
So my problem is that once my phone goes into sleep mode, when I turn it back on, it no longer connects to a phone signal. This is not the same as the Wifi, which I have no problem with. This is phone, 2g, 3g, 4g. I have to completely power cycle the phone to get a signal again, and even then it only lasts for as long as the phone is awake. I've tried a factory reset, but still no luck.
I know this might be hardware issue, but since I have no recourse in that event, I was thinking of trying a custom ROM and/or Kernal. Do you think these would likely fix the problem? For that matter o you think they would even have a chance? Od does someone know of another fix?
