[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.

Just got Shift, Having Data Issues

Well I just upgraded to the Shift from the Samsung Moment, but with the data issues I'm having it sure doesn't seem like. I cannot connect to 4G even though I'm in the heart of a 4G area (zip code 75001, just outside of Dallas). Every time I scan for 4G service, it just says Disconnected about 5 seconds later.
Using the Speedtest.net app, I'm averaging maybe 60-70kbps download speed on the 3G network. When I download apps the downloading generally pauses for several seconds.
For the record, I have done the data reset (##3282#), but that didn't help at all.
Any suggestions, or could it be I just have a bad phone?

Done that a few times but still no improvement.

Hm
I think it would be wise to talk to a Sprint representative over the phone, or show the problem to them in person.
It kinda sucks to pay a $10 monthly surcharge for 4G if you're in the network and are not getting it (worse if there's no 4G nearby)
I myself have not used 4G yet (live right on the edge of the network)
They should hopefully help you out
I too have a problem with connecting to 4G but that may just be my area

I know you have probably already done this but I would try powercycling if you haven't already.

Try comparing it to the display. I noticed that the wimax radio is kinda deaf when compared to my old epic. It doesn't lock as often as the old phone. There might be an update that helps some of these issues.

Ok you need to reactivate the phone pretty simple to do
Get ur msl either from msl reader on the market or ask sprint
Go to dialer dial ##3282# hit edit mode and enter ur msl
Click on data profile then hit the menu button and click restore
Let the phone reboot and go through hands free activation again
Tada speeds should be back to normal!

Appears to just be the location I'm in at work. Just tested it while I was driving around and got good speeds: 4G (at 6-8 megs download) and 3G (.5-1 megs). So I guess my phone is good.
Thanks for all the suggestions.

Mine won't pick up at work inside. I step outside and it is fine. :-(

I'm having same problem. I did a side by side with my phone and the display in Sprint store...I got about 120 Kbps and the display got about 1200 Kbps.
I don't know if the store is doing the 3282 thing every day on the display, but when I do it I get a bump up in speed then it decreases again over time.

Mine does the same thing, I've had sprint smartphones for over 2 years and all have been at a constant 70-120kbs (kilobytes) however this phone averages about 30-40(kilobytes) using SpeedTest.net app and the meter is very jerky as if it's having trouble maintaining a data connection. Occasionally the phone will spit out 120-130kbs with a rock solid meter, but then will revert back to the constant 30-40kbs tests.
I've tried the ##3282## to reset the data profile, reformatted the phone a few times and updated the profile and PRL. My battery life is also not very good at all, and I'm assuming because it's having such a hard time keeping a cellular connection.
I hope the radio is not dead, and that a simple radio update would fix this problem.
I'm open to suggestions as this is really driving me insane, but I love the phone.

I was having a very similar issue, and when I checked ##33284# under evdo, it showed failed. Apparently 3G connection or not the phone shows the 3G icon.

I didn't know about the ##33284# field test, thanks for sharing. My Evdo status is connected. I noticed that both the Evdo & GPS list Latitude & Longitude and both of them are different, and are hundreds of miles off from my locations, seems a bit odd.
I'm hoping HTC is aware of the inconsistent data problem and will send an OTA update to correct soon.

I'm really disappointed in the 4G (maybe more of a Sprint issue than a Shift issue?). I can never connect to it very long before it goes back to scanning for a network so basically it's not worth the battery drain it causes. I'm primarily in areas that should get 4G easily.

Thats weird, at work, in Charlotte, my 4G flys, its almost faster than the wifi at my apartment.

First test was unplugged while holding it, 2nd plugged in while holding it, 3rd unplugged while not holding it and 4th was plugged in while not holding it.
I did get a test that sad 1.1m in between there, but I threw it out figuring it was a fluke.
I haven't done anything to the phone but remove the mp3, stocks, peep, nfl, and nascar apps. Haven't done the ##3282#. Seems pretty consistent on my end, then again it is 2:30 in the morning here, but it seems to be good for me all day.
It does seem that holding the phone makes a difference, to me at least.

what is considered good 3g speeds? Just tried mine at home and it is
509kbps down
63kbps up
this test done with the phone laying on the couch. Then I picked it up and did the test while holding
171 down
31 up
I only had 1 bar while doing these test. Seems as soon as I pick up the phone it the signal strength goes down.

also, by signal strength goes up when I have the keyboard slid out

just adding in about the speeds, i've been getting good signal and data rates everywhere i've been so far with the phone. then again, its winter, so i'm not traveling atm. We'll see what happens come may when i'm going through the mountains of WV.
and i can get good 4g while at work (close to DC, but not that close).
my speeds are: down/up
wifi -- 18mbps/7.5mbps (note, we have a 50mb/s pipe coming in the house)
4g -- 4mbps/1mbps
3g -- 0.8mbps/0.3mbps
i dunno if those are good or not, but gotta say, they beat the hell out of what my old PPC6600 got with its 1xRTT connection. cant wait to get tethering to work on this thing.

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.

Data dissappears during phone calls? Realization time

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.

[Q] Signal bar goes from full to nothing randomly

Ever since I got a replacement phone Ive had this issue- while on the Sprint network my signal will randomly go from full to nothing at all. Yet when I use roam control to go into roaming, the signal always stays at full strength
The other thing I noticed is that when I dial into the 3282 menu, someone elses username is there instead of mine. When I run connectbot and use getprop, no MSL # is there either
Anyone know whats going on with the phone and if this can be fixed?

getprop ril.MSL
It is filtered from just getprop.
My signal has always done that.
Updated profile may fix the user name?
Sent from my SPH-D700 using Tapatalk

Thanks that command did the trick to get the msl- I was able to go in and manually change the username now.
Is there any settings in the data menu to improve the signal? Its almost like its jumping back and forth between a good and bad tower?

Not that I know of. That is what I suspect is the case with me as I have about 3 towers that are surrounding me from various sides and I think it is hopping between them... not sure there is anything to do for it but I haven't really seen any ill effects from it.
Sent from my SPH-D700 using Tapatalk

The weird thing is it never used to do this before when I first got the phone. When I was in the same areas the signal bar was always full and would never drop. I wonder if its a tower issue or something they changed with an update.
Sometimes when people call me they say it goes straight to voicemail though which worries me

Could be the modem. Some people think el30 is not as good as ei22 or ec05. Maybe try some others.
For calls calls going to vm, that can happen if you are using data in a 1x area. Also can happen if you have accidentally switched on ddtm in call settings.
Sent from my SPH-D700 using Tapatalk

This is going to be plain and a tad bit retarded but a solution is WiFi, as far 3G and 4G mine has always done this but i can testify that in my house i used to get ****ty service like 0 to 1 bar when i was on EC05 i switched EL30 now to FB15 and say much more improvement more consistent to 3-4 bars.
PRL updates could help if you roam around there. newest as of today is 60685

I've been having this problem too for about two months now. But as you said roaming works fine so I just assume it's a sprint tower issue and force roam whenever I'm on wifi.

I have had this issue for a year or so... started a while after I first rooted.
You can hold my epic in one hand, my wife's epic in the other... her bars stay steady, maybe fluctuate between 2 or 3 bars occasionally... mine randomly and erratically jump from 2 or 3 to nothing, stay there for 30 seconds or so... and jump back up.
While its annoying and distracting, I've never had a problem with dropping calls or losing data. I even took the phone apart to make sure the antenna had not come loose. Problem persisted over several roms and several modem Odin flashes, just won't go away!

Mine does the same, it'll have full bars, drop down to nothing, but my 3g/4g still work fine (off wifi)... i just ignore the signal bars because most of the time my data still works, albeit a tad slow.
