I searched all the threads and found nothing on this as far as I can see. I have been having this since day one with my G1. Every time I receive a call on my G1 or during the call it drops from 3G to GSM. I had stock T-Mo roms on my G1 (Pre/Post Cupcake) then JF 1.51 and now cyanogen 4.0.2 and this problem persists. I called T-Mo a few times on this and they exchanged my G1 3 times and gave me a new battery and charger free of charge. Does anyone else have this issue or know of a work around? This happens when I am at home and work. I travel for work to different locations and it still happens. When my phone rings it automatically drops 3G and goes to GSM (no icon next to the radio icon in the status bar). While making calls it stays on 3G for about a few seconds before it craps out and drops to GSM. It totally skips EDGE and GPRS. T-Mo said they sent out radio antenna tech's to the antennas near my home and they said all is fine and dandy. I live In Queens NY and work in the Bronx. When I travel to Brooklyn its the same as well as driving though Manhattan. I hope someone can help me with this.

ive always had this as well .. just never considered it a bug lol ... but i could see why someone would wanna keep their 3g while on a call .. reminds me of how sidekicks would lose data connectivity due to a call

Could you elaborate?
If you've had 3 G1's and a tech says there's nothing wrong with the network then it's clearly an issues with cupcake, be it a feature or a bug...
I don't really see why you would want to keep data conectivity while in a call, (unless you're downloading something in the background..?) so it sounds like a way to save battery..

Here's a perfect example where 3G would rule when working properly.
I'm talking to my wife on my BT headset while driving home from work. I have my G1 on my dash with google maps running with traffic patterns showing. While talking I am able to talk clearly on 3G and still see where traffic is building so I can avoid it. Being stuck in rush hour in NYC sux homeless man [email protected] Whenever I do this and my 3G connection drops my call quality drops and we both hear it while we're talking and then it cuts in and out and the call drops then I dont get updates. It's a feature I would really like to have. Even when Im working and talking and downloading a new update of an app. This happens when I am at a static location as well. I know driving from cell tower to cell tower can have bad effects but it does the same when I'm just at home or any of my work locations. When 3G works properly which is rare its amazing. Its helped me get un lost and find my way many of times.
Point being when T-Mo released the 3G statement they said all users with 3G phones will expierence higher call quality from the extra bandwidth. Why would they cap or or disable it when they are promoting it? I see the the point of saving battery life but it still shouldnt be happening. 3G is made for that feature to work voice + data being accessed together.
It might just be there 3g network, imo tmobile reception is horrible. Like at my house it is so f'ed up, I can sit in my chair and have 3 bars then walk 2 feet and lose service. It does this all through my house and at my work. They said it must be something in the buildings I am in, bull**** I say because ATT never does that nor did vzw when I used them.
same thing happens with me and 3g and calls..also about the house thing, hows this one for u ill be sitting in the same spot and have good 3g reception and all of a sudden it drops to edge. I know a way around this is to set phone to 3G only but then in areas where theres non im screwed
I don't get it. My wife who had the original iPhone and then 3g and now 3gs never had this issue. She would stay on Edge and 3g depending if she waned to save batery life. My old BB 8700g would always stay on Edge never drop to GSM in my apartment. My 3G doesnt even fall to Edge it goes right to GSM. This is really annoying.
every t-mobile phone I have does this
I'm pretty sure its normal
No one knows if this is a hardware, software, or network problem. Except maybe HTC/T-Mobile/Google.
If your phone stays connected to 3G, it's all good. If it drops down to EDGE, even if for half a second, it will NOT reconnect to 3G until you hang up.

If any of those 3 know they should fix it or at the very least advertise that the calls you make are dropped to the lower bandwidth of the GSM network.
T-Mo finally got 3G for the last year don't dumb it down guys. Fix this.
Yes it is true once your phone drops beneath 3G it will not go to 3G until you hang up the call.
try running 3g only or wdma only by creating phone info shortcut on anycut .. im going to try that out and see if it ever drops .. should be a temporary fix for you atleast with the whole maps thing and such but if you ever in an edge only are your screwed

I changed it to wcdma only in phone info. Hopefully this works. Everywhere I travel to throughout NYC has 3G. Hopefully this works. Also I have noticed that when downloading anything from 3G be it the market or browser it would drop from 3G to Edge as well.

While at home downloading apps from Android Market on 3G with wcdma only selected the radio dropped with no netowkr connection. Bust.

Did she use att or tmobile with the iphone? Because att has a much stronger 3g network then tmobile which could be why. I am pretty sure it is something to do with tmobiles network and not your phone, perhaps your area has to many users for it to stay on 3G. I have read about how the cell towers work and they have only so many bands for each user to access at any given time so if tmobile doesn't have enough towers or those things mounted on the towers it may be set up so you only get 3G for data usage and not calls since they don't technically require it to work.

My wife is on ATT. Isn't lower frequency better at penetrating through walls and such? (T-Mo 1700 MHz and 2100 MHz compared to ATT 1800 MHz) They haven't booted their 850 MHz antennas yet so I hear.
If that is true then why not boot me down to Edge or gprs why all the way down to gsm? I been living in the same area for 26 years. I have been with T-Mo before they even had antennas in my area and walking outside was the only way to get a signal with my phone. Now I get full reception in and out of my apartment and 3G connectivity in my apartment with a signal strength of -93dBm through out my apartment on 3G and -79 dBm on Edge.
T-Mo stated that this should not be happening. Hence the 3 phones new battery and charger and techs to the antennas. I'm starting to think its a HTC Android problem and not a T-Mo problem. Hopefully a new radio update can fix it.
I didn't even know GSM was still used in that way, I thought GPRS would be the bare minimum. How can you tell the difference? I use to only get a G icon and I looked it up and for the g1 it said that meant GPRS, what does it show for GSM? Not like any of this matters though.
I really have no idea why all this is happening to your G1 but I hope it gets resolved, good luck.
edit: on the tmobile coverage map it says edge/gprs and 3g, no gsm. does that make any difference? I checked for NYC overall not any specific boroughs.

GSM is what Edge Gprs and 3G run off of. Think of it as a progression. GSM>GPRS>EDGE>3G.
The way I know it is on GSM is to the left of the Radio icon on the home screen there is another icon that shows the network your on. 3G=3G E=EDGE G=GPRS and no icon means GSM. GSM is still being used. Most SMS and MMS messages get sent to your from through GSM while you are on a call.
I got an email while on a call without wifi. I'm in dallas. Anyone else getting data and voice now?
Has been possible since the beginning of time as long as you are on 3G
I concur. ↑
Sent from my Nexus One using XDA App
Really? I've never been able to do that until recently.
Usually when I'd start a call I'd lose the 3G icon and if I received email while in call it wouldn't show up until after I hung up.
Couldn't mess with data without wifi.
Used to do this on my cliq and G1 as well...
Odd.
Also been doing both (on TMob 3G) since February...
Any gsm phone can do that, but it is impossible for cdma
Your phone may have been set to WCDMA only up until now.
chalk that up as a win for GSM and a lose for CDMA

WCDMA is 3G, it has nothing to do with CDMA
In a weak 3G signal area, the phone usually does a handover and transfers the call to the GSM network when the 3G signal falls under some threshold, and GSM doesn't support simultaneous voice and data (icon disappears while on a call)
maybe you have better 3G coverage now and your nexus doesn't need to go the GSM route
I've noticed problems with using data and voice together too. What seems to happen is that it works ok at first, but the instant you lose 3G it never comes back until the call is over, no matter how good your signal. Very frustrating when trying to use your data while on a long call.
Both AT&T and T-Mobile (as can any GSM carrier worldwide) can do voice and data at the same time as long as your phone has a "3G" connection visible while on the phone call. This has always been possible.
What you may see happen is that if you wrap your hands around the bottom of the phone during a call, the signal may drop to "E" or Edge. You can't use data and voice at the same time if your phone is on Edge.
To alleviate this, use a wired or Bluetooth headset, or hold the phone with your fingers rather than your whole palm.

Have you ever seen my problem where once the signal drops to Edge it will never go back to 3G? It doesn't seem like normal behavior to me but it seems to always happen when I need my data during the call. I've been stuck on multi-hour calls where my phone refused to go back to 3G almost from the beginning, and then the second I hang up the phone goes right back to a 3G signal with full bars again. Very frustrating!

the ATT 3G network is not setup to do handoffs from gsm back to 3g. it currently will ONLY handoff from 3G to gsm during a call, and if you are still on your call, it will not switch back until you hang up. in the future this can be enabled both ways. tmobile apparently is setup the same way for now. so you're experience is normal until they reconfigure their network.
Actually it depends on the phone hardware. It IS possible to use GPRS and voice as well if the hardware supports it, its not only something available on 3G/UMTS/WCDMA. There is a pretty even split between class A and class B phones these days, you should look up the specs of the phone you're using.
Nearly all 3G devices allow you to use data and voice together since it isnt timeslot based and so voice and data is logically split and not time divided. This means you dont need specially designed hardware to do it, just the processing power to do it.
Class A
Can be connected to GPRS service and GSM service (voice, SMS), using both at the same time.
Class B
Can be connected to GPRS service and GSM service (voice, SMS), but using only one or the other at a given time. During GSM service (voice call or SMS), GPRS service is suspended, and then resumed automatically after the GSM service (voice call or SMS) has concluded.
Class C
Are connected to either GPRS service or GSM service (voice, SMS). Must be switched manually between one or the other service.
@kam187, thanks for that. I've been with T-Mobile since they were Voicestream, about 10 years now. And I thought I was making voice and data connections with my Nokia phone years ago, before their 3G rollout.
Here is the last phone I used before going the G1 route.

I got my G2 a couple days ago and I must say this phone is amazing..coming from a g1 I had for 2 years its quite an improvement. The only minor problem I'm experiencing is with the radio signal..most notably in my house..on my G1 I always had signal and internet connection. Now with the G2 I constantly loose connection all through out the house and the only way to get it back is to switch the airplane mode on and off and it picks it up right away, only to go away a few minutes later..I don't seem to have the problem anywhere else.
Was wondering if any of you guys can shed some light on if there is a way for me to figure out why the signal is so random in my house and it was ok with the G1. And why airplane mode seem to fix it for a short while.

did u activate the sim card that came with the phone or still using the old one?
I'm still using the "old" one still but considering I got it 2 months ago I wouldn't think its a big deal unless the sim that comes with the G2 is any different?

I asked because i was told to activate the new sim card to avoid issues likes the ones u seem to be having.
I was told to replace the sim card as well. After doing so there was no change in the reception of the unit. The downside is that the sim card does fine in my Vibrant but does not work at all in My Nexus One. Tried two different new sim cards and each time the Nexus One refuses tacknowledge it while the G2 and Vibrant do. I have found no difference in signal quality or strength with the new sim. The new sim card has a much smaller gold contact area and that area is a slightly different shape,
I went ahead and activated my new sim card to see if maybe it'll fix the problem..ill let you guys know how it goes
Sent from my T-Mobile G2 using XDA App
Changing the simcards will not work. If I put my simcard in my iPhone 3G or my G1, I'll have 2 or 3 bard with 3G, but with the G2, It switches up all the time, from Edge to 3G or no data at all, with 1 or 2 bars. I also have five other family members that also have T-Mobile phones and their getting about 4-5 bars on their phones. So it's not the sim or a tower issue.
There's cleary a problem with these phones.
This mourning I woke up and found the phone with no service, no bars. I reset it and came back, this afternoon I left the phone on my bed, came back to it, and again no service, it seems the service keeps going out for no reason.
Another is, I live in a big building, when walking in and out the building, my data connection will drop, or sometimes I won't even have any service, and again the only remedy is to restart the phone to get service back, airplane mode won't even fix it.
Yea the new sim hasn't really fixed anything at all..

damn i was about to try that... guess i'll keep waiting... maybe an OTA radio update will help this cause it's really getting annoying.
I don't have a problem with my G2 dropping signal completely, but I have noticed that my 3G is very spotty. It's probably because I was spoiled the the MyTouch Slide's 3G only option.
Yes, I've noticed that the signal isn't quite as good as my G1. It's seems to be about on par, if not slightly below my friend's Vibrant.
But remember, the G1's radio really sucked once upon a time. Radio updates. They will come. Every phone that has OTA updates always gets new radio, in my experience.
I'm on my 3rd G2, mostly for manipulating the purchase price, and have noticed on this 3rd one that the spring is looser than the first two, the phone resets itself and often, and I'll loose data even though it shows I'm connected. This will happen in edge or hspda. I'm taking the phone back tomorrow.
Crappy thing I just put the ZAGG complete invisi shield on it. WIll Zagg comp me another cover you think?
If only Tmobile would activate the UMA calling over wifi. This would be the perfect phone with perfect service.
I am going to call tmobile in the morning and see if I can get any word on the UMA release. If not, the phone may have to go back.
I'm having the same problem, not at my house but at a local ihop that happens to be walking distance from where I'm moving in a week. I tried a reboot, airplane mode, even pulled the sim card and nothing worked. I got signal back once I left, but since it's right by the new place I would like to not have to deal with this.

well ive been searching around and i think ive found something that could help..
if you dial *#*#4636#*#* you will get a little screen of information about your phone, go to phone information, under phone information scroll down until you see select network type, the network should be automatically set to "WCDMA preferred" ive been playing around and i set mine to GSM/CDMA auto (PRL) and since then (about an hour roughly now) i havent lost my signal or connection in the same spot i was loosing it in my house every 10 minutes or so. not sure if this fixed anything but so far so good. definately will let you guys know if it continues to be good or if it doesnt stay consistent.
heres some information also in case you dont know which one would be best for you.
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

phone came in wcdma preferred stock... I came by that option too but I would much rather suffer with spotty signal [HSPA] over Slow edge speeds...
that said I may turn on GSM only when I'm indoors with little coverage, should save a lot of battery.
is there a setting that forces the G2 to go for the G3 or H setting instead of the edge? I live in an area where my phone can get both and it always goes for the edge signal instead of a weak H signal and the edge is soooo slowww.

I was looking in the Samsung whirlpool forums for a separate issue but came across a possible solution for a problem I've had on my Atrix since day one here in Australia.
Problem:
When I connect to data, the upload arrow will get 'stuck' and time-out forcing me to restart my phone / toggle airplane mode to gain data again
My Question:
Is it possible for someone to track down the service code that allows me to disable/change HSPA revision numbers for the Motorola Atrix? (see proposed solution for the codes needed)
Any help would be greatly appreciated! Infact I'd probably paypal you some money as soon as I get it since this has been such an outstanding issue for so so long for me!
- DarkRyoushii
Proposed Solution from Samsung for Samsung Devices:
****************** FIXED ******************
The problem stems from the fact that this phone has 3 forms of data connection, 3G, HSDPA, and HSPA+.
3G is what we have all had since 3/Telstra launch 10 years ago.
HSDPA is the 7.2mbps connections that we got after that.
HSPA+ is the full fledged 42mbps Next G stuff that only Telstra has.
The problem is, when you are just using the phone as "a phone" it idles on a 3G connection to save battery and when you initiate a data connection it flicks on to the higher connection protocols for better speed.
What is supposed to happen when you initiate the data connection is the phone checks for H+ connection, then for H and then finally 3G. For some reason if you arent with Telstra or are in an area without HSPA+ the phone gets hung up for too long attempting to initiate the H+ connection and refuses to drop back to H!
Also, even if it does give up on H+ it then has an issue with falling back to 3G. Resulting in the problem that if it cant get H+ or the tower is too flooded for a H connection you get absolutely nothing until you restart the data mode within the phone, renegotiates with the tower and BAM, you are back in business.
So... there are 5 fixes;
1. Wait for KE9 (or what ever firmware fixes the modem timings etc)
2. Get a Telstra sim and never leave an area that has H+
3. Turn off/on data mode whenever it happens
to which i told him they were stupid answers and completely unacceptable, but then he came out with this complete gem!
4. using service code *#301279# you can turn off HSPA+ completely forcing it to start the data connections on HSDPA
5. using *#301279# again you can just turn off HSPA+ and HSDPA meaning it instantly starts downloading the data on 3G without delay
Now yes, i thought... great... ive bought this $779 phone that has all the latest and greatest technology and I cant even use it! But, I did some testing!
First of all my normal sim is Vodafone so turning off HSPA+ is an obvious one for me, im never going to get it so why bother. So now that the phone only attempts to get a connection with HSDPA the need to turn off and on data connection was getting more and more rare but still having the problem (i have a feeling that is due to congestion?). So i bumped it down to 3G only and it works perfectly 100% of the time!
The point of these faster connection protocols is speed so i did testing.
Vodafone sim, 4 bars of signal in the middle of a shopping centre.
HPSA+ turned on = 4mbps down, 1mbps up
HSDPA turned on = 4mbps down, 1mbps up
3G only = 3.5mbps down, 1mbps up
did this over and over and over again and to be perfectly honest, im willing to lose 500kbps to make sure that data always works and if you are just doing general web browsing the time it takes to initiate the HSDPA connection wastes more time than the slightly slower speeds with 3G does.
Now obviously this only works fine in my situation, if you are with Telstra and going from HSPA+ down to 3G means going from 20mbps to 3... i would be pissed. But for the rest of the country you are talking about a loss of less than 1mbps so in real world situations with just small amounts of burst data its fine
TLDR; Try and go online and the 3G up arrow lights up but never actually downloads anything
Dial: *#301279# – Change HSPA revision – Release 5 HSPDA only
test, if still a problem
Dial: *#301279# – Change HSPA revision – Release R99 HSPA off
Your welcome, Peace out!

Didn't Atrix radios from stone age have this disabled? I'm not sure though, I didn't participate in here back then; maybe a forum elder can comment on it.
Dumb question but did you try those codes (the numbers only) like this *#*#number#*#*?
sent via tapatalk from my CM7 Atrix
*#*#4636#*#* gets you into some phone options. From there you can select a bunch of options. Not sure if there is anything in there you're looking for.
the codes in the *#*# format doesn't work, it just deletes the number when I finish typing it.. and the other menu 4636 doesn't have the options I'm looking for but thank you both for your suggestions
this phone has started playing up, 4G wont connect at all and 3G is constantly changing between H and H+. Phone calls dropping and battery draining fast.
Have tried factory reset
flashing older Samsung firmware
Nothing is making a difference. Tried my SIM in another phone and it instantly connects to 4g.
This only started about two weeks ago.
Any one else have this issue? i'm in the uk on the 3 network.
UPDATE: it appears the 4G radio is faulty - setting it to 3g only solves the issues.
UPDATE : I'm so gutted that this phone 4g/3G is ****. Love the phone but loads of people and reviews suggesting 4g/3G issues with this phone and high number of call drops. I did a test today, I put my sim in an iPhone 6 and instantly connected to 4g and speed test was through the roof peaking at 38mb. Put the sim back into the s6 edge plus and only connects to 3G. But unable to browse the Internet. This confirms my fears that the 4g chipset/antenna are ****. In this phone. Which is a real shame as the phone is my favorite ever. Going to get an iPhone now. Connectivity is the most important thing and I can't be dealing with this crap from such an expensive phone. Shame on you Samsung.

I have the exact trouble as yours whichs about constantly changing between the H and H+. (4G is not matter, its new around here). When it turns on H, doesnt connect any site and application which need data connection. But H+ is doing normal. I bought an unlimited data package is provided for up limit 7.2Mbps. Dug something and saw that HSDPA(H) technology's up limit is 7.2 for our carrier. Then bought limited turbo data package(shows as up limit 43Mbps) but still changing H and H+ Thats not such for current device. It was in such an annoying situation since H+ available to connect. Tried to force use H+ but no luck. Sorry for long article and bad grammar. Just saying. Thanks.

Been doing a lot of research and it appears to me that this phone is crap at holding 4g/3G signals. I think this is a hardware/design fault. Most people won't release this until they test this on an iPhone in the same location and see the huge difference. Can't believe Samsung would release a huge pile of crap.
