Data dissappears during phone calls? Realization time - myTouch 4G Q&A, Help & Troubleshooting

Has it always been like this? Flashed a few roms and radios. But I think I never really thought about it or noticed it until now and it's really bugging me. I've read a few topics about 3g and 4g being "parallel" to our voice calls so we can't have both? I don't quite understand any of it.
Can someone tell me it's just my phone so I can try to solve the problem, or reassure me that we can't have both at the same time so I can sleep better tonight? lol
Thanks for any and all help!
Edit: Sorry meant to post this in the question thread.

ALL GSM phones that are connected to HSPA or greater should be able to talk and surf at the same time. I do it frequently personally. Do you know if you drop to EDGE/GRPS when you get on a phone call?

I am also having this issue but its strange that the guy posting above me does not face this issue - may be it is a hardware issue like screen and emmc since I already tried different roms and radios?. As soon as I am in a call I am disconnected from network data. I noticed only recently when I was in a hotel room working on my laptop (tethered phone to provide internet) and just when I joined a conference call, I lost internet. It was so embarrassing I couldnt curse tmobile and htc enough. The iphone ad about talking and surfing at the same time never made sense to me before this incidence.

my phone does this too, but its on and off. Sometimes it does, others it doesnt. I really have no idea what could cause it.

Let me shed some light on this....if you are on H will less then 2 bars and theres an E with 3 bars or more and u get a call the phone will switch to E but once you hang up then its back on H. But if H has 3 bars or more when a call is received then I will stay on the H network and allow talk and data at the same time. Theres no hard ware issues trust me. Hspa is preferred but if there is a stronger signal then the phone switches. I hope that makes sense. You can not do data and talk together on E but you can on H.

Or, to put it in other words: when the phone is in a call, it'll hop to the "best sounding" base station, and if it would happen to be the old GSM/GPRS/EDGE base station - the data will drop. The missing bit is: once it drops - it isn't re-negotiated during the call, only after it. Thus, if the phone hops to EDGE base station even for a second during the call - you won't have data from this point and till the end of the call.
Perfectly normal behavior.

This is definitely not the case. I have tried multiple times with different signal strengths but it drops completely every time. I just did another test, I was on H at 3.47mbps with all full bars and as soon as i placed a call to my friend, the data dropped completely.

It's not about the bars you see, but the signal strength (and not only) your phone sees - which is way more complicated than just bars. Read my post above.
And it's not an opinion either, it's a fact. This is how cellular handoff/handover works. http://en.wikipedia.org/wiki/Vertical_handover

Thanks for the replies and insight everyone. Now I know a little bit more about how that handover works heh.
In my case, most calls were made from my office building. Yesterday, when I posted, I had the newest radio and data would drop immediately as soon as the person answers my call (not a steady drop from 4g-3g-Edge, icon just disappears completely). At best, I was able to download a few apps during a call (which was downloading before the call was made) but as soon my screen locked and turned off - the data was gone on wake and wouldn't turn back on until after the call was finished.
Went through 4 different ROMS yesterday with about the same results but I have recently reflashed RoyalGinger again along with the stock radio thereafter and it seems to be holding during calls, even on my ride to work this morning. I know this is against what most people have said in this thread but maybe I just messed something up on my phone with the new radio? Guess I'll stick to this radio for now. Thanks again everybody.

Radio is the one responsible for determining the best possible connection, and flashing new radio might change things.
I'm in a good 3G/H coverage zone, with new radio, and just tested - the data remained on during the call in any conditions, screen off, screen on, wifi toggling - still worked.

When I'm on 4g and turn the screen off the data turns off, normally after an extended period, which its good for battery.

This has happened to me since I had my blackberry 9700. My experience has been that it loses all data (H/3G/E), even in good H/3G signal area and won't reconnect until I end the call. However the data loss only occurs while on a call. While not on a call, just surfing the net or using data any other way does not cause lost data connection nor a drop from H/3G to Edge. I saw somewhere on these forums that switching to H/3G only will prevent this from happening. I've tried this and it seemed to help, but I haven't been checking on every call.

call does not end automatically

sometimes while speaking to someone the sound of the 8525 goes blank and i am unable to end the call and the timer keeps running till eventually it ends by itself usually a min or minute a half after. this occasionally happens also when the person on the other line ends their call.
help me!!
oh yeah, when it ends call, i lose service and i have to wait for the phone to pick up reception before i can call the person again
I am sure that one of the more experienced members may have a better idea, but I had this problem in low signal areas when I was on radio 1.34. It stopped happening when I upgraded to 1.38 and so far hasn't happened on 1.40.
Something to try anyway.
This happens to me quite frequently in my house!!
Next time this happens notice if the network indicator has dropped from U to G during your call. When it happens on my 8525, the call wont terminate. So many times while im in my house ill band tab switch to GSM just so it does not do this..
I had one go for 63 minutes in my pocket once... so i checked my usage, and it was only shown as the 2 minute call I actually had. So it did hang up from the network, but my phone was blissfully unaware. I'm not so sure however if someone else called it would have rung.
Hope this helps, let us know if it's changing from U to G !

Seems like you have the same issue I had at work, two low level signals and it hangs trying to switch between continually. Has upgrading the radio helped you at all, or was it just coincidence for me?
im currently on radio 1.38, maybe if i switch over to 1.40 ill see, but i will def keep tabs if the network goes from U to G.
thanks for the help guys i switched my network from "any" to "gsm" only, and so far so good, i guess the problem was when the network would switch over from gsm to wcdma im not totally sure. anyway i chose GSM as the network it should always be on, and the network indicator always has an E on the top. is it fine if i keep it at GSM or will i run into problems/ or not recieve full benefits of something? some1 please educate me thanks

Data Issues??

Occasionally I get no data connection & I have to restart the phone, does any body else have that issue?

I have that issue as well, idk why it happens but I'll add it to the list of problems for when I call to get a replacement.

That just happened to me today also. It switched from "H" to "E", then when I opened USA Today it FC-ed and the icon turned into a generic Android one like the app was on the SD card and unavailable (even though it's installed to phone) and then 5 more background apps that I didn't even know were running FC-ed (Amazon MP3, Finance, QuickOffice, something and then Facebook three times?) and the phone locked up. I was able to power off then back on, but data never came back even after waiting about 10 minutes until I powered off and on again. Quite odd.
I get the same issue where am connected to wifi and as soon as i walk away from it it doesnt connect back to the data network. I got a replacement phone coming so hopefully i dont have the same issue. Another thing is the random reboot and i get black screen a lot especially after rebooting

I've had the issue, but each time it appears to be related to JuiceDefender not properly enabling the radio. If I shut JuiceDefender off, the connection comes back, although sometimes its just easier to airplane mode it and be done with it.
I called T-Mo about it, they said call about a week after the inital release date and see if they have a fix by then, there isnt enough information kept since it hasnt been officially released yet.
I'm having the same trouble. Are you guys on the new sim card? I popped in the new sim card and the tech told me to not use it and just save it. I noticed when I put the new sim card a notification of a new voicemail came on. I didn't have any voicemail.
Edit: I'm starting to have some serious data issues. I'll get cut off, but my phone will still show full bars and "H". I try the whole airplane thing and it still does nothing. I constantly get the "check network setting, try again or cancel". My market wont load, browser says "unable to connect." This is getting stupid. When I call T Mobile it always start working and then cuts off shorty after hanging up. I've never had this isssue before. I live in the middle of the city. Only 3G around here. Its getting annoying.
Guys I'm afraid that it might problem with the antenna placement. Holding the phone on the bottom half will drop me from 3 bars of "H" to 4 bars of "G", then it will bounce back up to 4 bars of "E". If left on a desk then it will remain at 3-4 bars of "H". I notice this especially at a place where I have low-mid signal, such as my school (reinforced concrete FTL). When I have a strong 4 bar signal, it usually won't drop all the way down to edge but I do loose a few bars. I hope a simple software issue is enough to reduce this effect. I might be being crazy paranoid but I'm definitely noticing a lower signal than on my G1.
Try holding the phone by the edges, then hold it in a normal grip and see if the signal strenght changes (Menu->settings->status->signal strength)
I just got off the phone with tmo and was told its a known issue with the network affecting about 10% of users. The issue started for me yesterday on my hd2. He also said they have people working on it. I asked if I could get my buyers remorse set back 14 more days to ensure the issue is not permanment but he said that they are no longer doing extentions. I'm sure if I get tranfered to retentions the answer would change. I hope.

I'm also having the same issue. I just rebooted my phone, so I haven't had the chance of switching airplane mode on/off yet. I'll let you guys know if that works for me, either way, I'm hoping there's a fix from T-Mo.

Wow that's funny, my MYTOUCH does the same thing with airplane mode off/on. I also remember that the store demo g2 I played with last night had the voicemail icon in the notification bar, but when you pull the bar down, there's no option to connect and retrieve the voicemail. I found that even weirder since the phone comes preloaded with google voice.
Also experiencing the same issue here in Phoenix. Been having it since I got the phone on Monday.
I have been in an ongoing round of tech calls and will be having a follow-up with the tech who I spoke with last night... I've tried everything from APN resetting to swapping the SIM card to a total factory wipe -- nothing is changing this for me.
I *know* my neighborhood has full 3G access, but I am maxed out at 1 Mbps. (Before the factory wipe I was getting 0.35 Mbps.) If this doesn't change I may just return the phone and switch to Sprint to get the Epic 4G. I mean, I'm not getting HSPA+ coverage either way, and at least with the Samsung Galaxy S Pro I'd have a full 5-row qwerty...
>_<
Wow, this is really too bad. I was SO excited about this phone...

If this happens, try going to settings->wireless->mobile network->network operators and see if you get an "Error while searching for networks" error as I did.
Reset fixed for me too. But it makes me worry.
I'm on a brand new sim card (switched to TM from ATT). I'm having some data issues too. I talked to TM tech support and they reset my connection but that did nothing. Now they're going to their android techs to see whats up.

[Q] my G2 loses service, restart brings it back

hey everyone
so my G2, which I absolutely love, has been having a problem lately. in the first week it happened maybe once and i didn't think much of it, but since Friday it's happened like 8 times now. I'll be sitting there with my G2 and all the sudden I have no service whatsoever. Just an x on the signal strength indicator. 1 or 2 times it has come back after a minute or two, but the other times I had to turn the phone off and back on. the weird part is I'm not moving at all, totally sitting still, but when it comes back on I have FULL bars with HSPA+. so it's not like I walked into an area that didn't get good reception.
any idea what's going on? i looked around but didn't see other people having this issue. any ideas?
thanks
alright well at least i'm not alone. i remember that rumored OTA update was supposed to have some radio bugfixes. maybe when the real OTA update comes it will have something to fix this. i hope so.
I have been trying to diagnose this issue on my phone too.
By any chance, do either of you have your BT on at the time?
Happens to mine as described and I have never turned on bluetooth. However this would also happen to my G1 so I think its a network thing personally.
Yeah, it definitely is. I have 2 areas that it happens in, both are while I am in my car and I have BT on in my car. When I ran it without BT, did not happen.
I have found that when I am in those area's, turning off 3G stops it entirely, even with BT on, so when in my car, I set edge and still use my BT and problem is gone.
I hope this is temporary and an OTA can fix the handoff from 3G to Edge and back better so that I can stop this, but this works well enough.
Mine has done that also, maybe once a week for the past 3 weeks.
Judging by the other problems you can have Id say this one isnt that bad. Especially if it only happens once a week haha. This is the only problem I have with my phone.
no bluetooth...
no no bluetooth on, i never do actually... but also my G1 never did this, which makes me think it's NOT a network thing, but I don't know.
also I'm sure this is just coincidence but it almost always happens when my girlfriend is nearby with her T-Mobile Blackberry Curve. i know it wouldn't make any sense, but she's sitting there on the same network with full service and all the sudden my G2 loses service completely, right next to her... although it's not always while she's there, but like the majority of the times she's been there.
I just started another post to check on something, I have widgets that show me when I am connected to 3G and when I am connected to H. I have noticed that the phone is activity managing that connection. In other word, it is in 3G until data is transfered then it goes to H. I wonder if when we are in areas of "questionable" HSDPA signal if this hand off is causing the problems.
I have seen a lot of op's say that there problems come right after some data activity?
Just a guess a this point
i saw someone mention in another post that it happens after/during a text message alot of times. i haven't noticed that myself, but that's something to think about too.

What I've heard is that the phone will stay in 3G mode until you begin using data in order to save battery life. Makes sense to me.

Sudden Drop signal

In the past few days, I've noticed my phone sometimes loses signal randomly: the bars will turn dark gray (not light gray) and there would be an "x" over the bars. Def. no "3G" indicator.
And it's happening in places where I normally get signal. A reboot doesn't fix this. I just have to wait until the signal is back up. I haven't installed anything new recently, nor am I running anything out of the ordinary.
Anybody else experiencing this as well? I did a quick search and wasn't able to find much.
I'm still on 2.3.2 (haven't gotten the OTA), unrooted.
I also experience this loss of signal. Constantly. Every time during a call.

Just to clarify, this isn't happening to me during calls, or hasn't happened to me during a phone call yet. Sometimes I pick up my phone, and I see I have no signal. And of course, attempting to call out or access gmail/internet proves it so.
It's very frustrating.
2.3.3 comes with a updated radio.
You can also fastboot the updated radio but your phone isn't modded.

I will need to clarify myself too, I meant I always lose the data signal every time I'm in a call. As for the phone signal (bars), I have no issues.

Are you on EDGE (2G) or 3G or WiFi when that happens? EDGE does not support concurrent use of voice and data, but the other types of data should.

[Q] Nexus 4 Signal Strength... Antenna Firmware Radio Problem? anyone else?

I have Straight Talk AT&T, and so far my experience has been mixed. Sometimes I get full reception and generally awesome speeds (coming from Sprint's slow ass network), other times I get absolutely no service, sometimes it randomly jumps into roaming and i can't get data.. and it stays 'stuck' in roaming mode.. I have to turn airplane mode on/off to fix it.
This all happens without my leaving my desk.
Apparently it isn't limited to Straight Talk AT&T though http://forum.xda-developers.com/showthread.php?t=2038963 http://forum.xda-developers.com/showthread.php?t=2037780

So it's been determined that it's not a hardware problem?
well its still early to tell. the phone is still very new so they have plenty of time to tweak the radio and fix bugs. lets hope its not some kind of weak radio hardware issue.
I've been having these as well. Quite annoying, but the data connection still pulls data and works. I've requested an RMA device and should be here tomorrow. Going to test with that, if it's the same then I'd keep this one I already have. Sometimes even if I have full service 5 bars, data will not work. The H will still be on stop of the signal bars, but it won't download/update any data, if I'm using any apps, it'll just hang.

What is the process for going about getting a replacement... and keep us posted on whether or not you see any changes..
let us know If the replacement is better. which I don't think so. but if your on original 4.2 with older baseband stay there. don't update and play with the data then. see if its good. then when satisfied update and see if the same problems arise then you know its software bugs

My N4 pretty much does the exact same thing. Actually, I'm on my replacement phone and it does the same thing as my first one.
which makes me believe its a software bug. or hardware fault. i'm having some faith in software lol :good:
I sure hope it's a software issue, because my connection really sucks. It drops out constantly, but never dropped out a single time on my Backflip during normal hours (only 2 times around midnight during server maintenance or something)
Do you think I should try T-Mobile and see if my issues are resolved..
I just discovered this phone info settings, via *#*#464 or whatever it was.. Is there a particular setting it should be on, not WCDMA Preferred?
I'm having the same problem: the signal strength is very erratic. I'm on Rogers in Canada, which is same frequencies as AT&T.
I've never seen such erratic signal strength before.
On the other hand, though I haven't had it very long and haven't put it through its paces, I haven't noticed any significant signal issues, like dropped calls. So, I don't want to jump to any conclusions that what I'm observing is actually a problem.
Does anyone know of an app that tests the quality of my data connection? I know everyone uses speedtest.net but that just tests burst speed and I'd like something that will test the consistency of my connection too.
same problem
I'm having the same difficulty. Signal can be at 3 bars then all of a sudden goes to 0 bars.
Has anyone determined if this is a software or hardware fault? Any solutions?
Thanks
