Title - meant to say randomly lose service and have to reboot
I have only had this happen about 3 times since owning the phone (since two weeks after launch). Occasionally, my phone will altogether lose service and display the blue circle with a slash through it, and I have to reboot the phone to regain service. This happens in an area where I have signal usually, when this happens. Does anyone else have this issue?
I had a problem similar to this last night/this morning. I didn't make any changes/mods to the phone either...
Phone was on the charger last night and when I woke up this morning I noticed I didn't have any emails. I still had the 3G icon and 2 signal bars, but anything I would try to do using internet connectivity wouldn't work (checking mail, navigating to google.com, etc.). I just shrugged it off since this has been the first time it happened.
For what it's worth, I'm running JF6 with UnleashTheBeast and the circle battery meter thing...
RE: Network loss, etc.
I've had issues like this from day one. From my testing, it seems to be related to the radios. (Both wifi and 3g.)
Stock was horrid for me, but then again, I live/work in a place with really crappy radio reception. It was tough to tell if the 3g or voice network service losses were just "the location" or something with the phone. But the fact that it's doing it with WIFI when I'm 3 feet from my AP, and no other devices are having issues is telling. Things have stabilized a bit with one of the SRE 1.2 OC builds.
That, and I'm now having intermittent sound issues too. (Can't play ringtones for a few minutes, then I can, then I can't, etc. )
I'm actually starting to suspect it's relating to the blocking filesystem lag. Almost as if some app is just killing the FS. I'll keep investigating. But it's good to know I'm not the only user who is seing service drops in strange ways.
I'm having similar issues with data connection, and i'm completely stock at the moment. My coverage is great so it just doesn't make sense.

Yeah, it's completely random when it happens, and it has happened two out of three times in an area where I have service...
I live in Manhattan, so my day consists of going underground for subway, and then back out at least 4 times per day. I have noticed several times that my radio never RE-grabs a signal when coming above ground it just sits with the bars and an X signifying no signal, in broad daylight...until i reboot the phone and it then promptly grabs signal. I have a buddy with a NS and he noticed this too...we also noticed it happens mostly when we are listening to something when emerging back above ground. Not sure if that has anything to do with it, or if it isjust cooincidence...however, has anyone else noticed their NS radio not grabbing a signal when back in range??? It is SO annoying to be walking around for 10-15min after coming above ground, to notice you have been cut off the whole time.
just instal the airplane mode on/off toggle
and hit it when you are back out on the surface
some times it's slow for the machine to grab signal
yes, i have noticed
like when i go into the basement, or server room, or other places with NO signal
and go back out to a place that I Know there is signal, yet it still in X mode
so, i just swap on/off airplane mode, and it works right away

I'm also a metro north commuter and the same thing happens to me randomly as well. I can go days without it occurring once, however sometimes it'll happen twice in the same day. Attempting to cycle Airplane Mode just locks up the device as well, so rebooting is the only option to restore network connectivity.
Noticed this as well when I'm in and out of subway stations. It hasn't been happening recently but sometimes playing around with the settings in the *#*#4636*#*# menu might help, like selecting GSM PRL or WCDMA preferred.
Anyway, I had the same problem with my Vibrant... never had the problem with my Nexus One or MyTouch 4G. Maybe HTC's hook onto networks better?

I normally loose signal completely when I am in the underground parking lot of my condo building. But as soon as I am outside it connects almost immediately.

I've got the exact same problem, not sure how to resolve it. Really wish they would push out an update and fix these annoying issues.
I've set my phone to WCDMA Only ( since and on boot up it doesnt connect to a network ) & WCDMA Perferred doesn't seem to want to stick.

i have the same problem
Same problem with my Nexus S. Toggling airplane mode don't help. I have to power off/on my Nexus S then I get the signal again.
So I have a perfectly good 4G LTE signal going, data speeds are great and all, but every once in a while it will just stop receiving data. The 4G LTE icon is still there, occasionally I see the upstream arrow flash, but the downstream arrow remains blank. A difference that I see from other people's connectivity issues is that I never once see it switch to 3G/1X when this happens.
One thing to note is that this behavior is not readily apparent until you're doing something real-time network dependent, like streaming audio/video for a considerable duration of time until it cuts you off suddenly.
Between 10 seconds to several minutes after data stops transmitting, it starts working again. Sometimes I get impatient and just toggle between CDMA only/LTE automatic to get 4G LTE working again without having to wait.
Is this a common issue among Charge owners? I noticed the reviewer at Anandtech had a near identical experience (though not always fixable without a reboot for him):
"My only complaint is that every once in a while, the LTE data session sometimes stalls briefly – sometimes for a a few seconds, other times for a few minutes. When that happens, you’ll see the uplink green arrow blink, but no orange downlink arrow. Rebooting the device fixes things."

After conversing a bit with him (he also reviewed the Thunderbolt/Revolution), this apparently only happens with the Charge, but he also has faith that Samsung would fix this through software (RIL) or hardware (firmware). Given Samsung's track record with smartphone updates, I'm not so sure they will.

Considering a month after the phone's launch we already have a Gingerbread leak I think this device will most definitely see support from Samsung. It is a DROID branded phone after all, and Verizon is statistically the best carrier for updates, they do take special care of the "DROID" phones over every other Android handset.
4G is flakey, on both devices that offer it. I have both the Thunderbolt and Charge with me most of the time, and I see all kinds of flakiness on both. It's the network.
It is definitely the network. I had a Thunderbolt before the Charge and it was FAR worse with network connectivity falling off the face of the planet despite having full 3g/4g.

I have had the same problem. I usually wait and it comes back in about 30-45 seconds, but it is annoying. It was really bad for a couple of days but has been better the past couple.
I personally haven't had to much issue with 4g dropping out. However people need to keep in mind that LTE is new for both the mfgs & carrier. So it is going to take time to get all these bugs worked out. That said I have to give props to VZW and the mfgs tho because back when they were building out 3G originally you want to talk about issues my lord was it bad.
I have had this issue, with the 3G and the 4G, but I can't say that it's a deal breaker for me, compared to the lousy HSPA+ signal my Vibrant had. It's only ever happened to me at my house, which is right on the edge of LTE coverage, so it switches back and forth a lot. But I have to give the network the benefit of the doubt for right now, it's a brand new network and a brand new device. And the 97% of the time that things work properly, it's so far above and beyond the T-Mobile network I have no regrets about switching.
I called Verizon with the same issue last Friday. Their resolution after a couple of questions was to overnight me a new (certified like-new) Charge and SIM card - the replacement was received on Monday. I haven't had any issues since, but I also stopped seeing the issue after I made the complaint.
Regardless, replacement has been better and locks a GPS signal much quicker. Maybe it's the SIM card?
SAME CRAP HERE!!!!

I tested if I have this behavior using LTE only mode (dial **583 in Phone app) and indeed I do, so this furthers my belief that my issue is not due to something wrong in the hand-off between 4G/3G.
I found out the way to actually change the data modes and tested using EV-DO Rev. A instead of eHRPD (in conjunction with LTE) and also using just CDMA 1X (in conjunction with LTE, essentially disabling 3G), but my issue of dropping data exists. The 4G LTE icon is displayed the entire time when it happens, I just seem to lose connectivity (and all three of the tests in the Phone Info area fail) temporarily. For what it's worth, I'm not moving the phone around at all when this happens.
I think I would actually be more content if when the data connection stalled, my 4G LTE icon just disappeared or if it switched to 3G because then it would make more sense to me (that I may have lost connection to the 4G service and it's attempting to reconnect to either 3G or 4G), but as it stands, all I get is a constant 4G icon with intermittent dropouts. The switch to 3G/1X seems to be the more common issue among 4G smartphone owners, but my (and the reviewer at Anandtech's) issue seems to deal completely within the 4G network, and I've tried every leaked radio to no avail.
The regularity of the dropouts seems kind of random as well; I'm not sure how I can figure out the source of the issue. Does anyone know if there are some logs that I can look into to see if something is happening to my phone at the very instant that I'm having these stalls?
Of course, I'm not discounting the fact that it might completely be on the side of Verizon's network and/or my area in San Diego and has nothing to do with my phone, and I may in a minority of users that actually continuously uses the 4G enough to notice these dropouts, which on average happen once every half hour to hour or so. Sometimes I'm able to stream something for several hours without the stalls, and other times it'll happen frequently within a short time span.
I just got off the phone with tech support for the intermittent data drop problem. After confirming that I was on EE4, and that I had tried doing a factory reset, he is fedexing me a new sim card.
Really hope it works, I love the phone but losing data for 1-2 minutes at a time randomly is pretty lame. Especially since I switched to Verizon for their reputation as the better network.

Is your problem the same as mine (data drops all while 4G icon is displayed) or is yours the more common 4G to 3G/1X transition or losing the 4G network icon data drop?

The data will stop. Then the 4g or 3g icon will disappear entirely for a minute. Then it will reconnect at either 4g,3g or 1x, I don't really see a clear pattern, it seems totally random to me.
Is there anyone who's reading this that regularly uses their 4G continuously (i.e. hours) for streaming web content (e.g. radio streams, live video streams, etc.)? If so, do you experience any occasional dropouts or is the 4G connection for you rock solid?

Tested on mine and same result.
Edit: Rebooted and it works fine been on it 20+ now, I'll be testing some more
A couple of days ago my SIM card crapped out.
Now that i have a new one my 4G signal has been more consistent and stronger than ever. I live in a fringe area and before the new SIM it would constantly switch between 4 and 3G. Now i go for hours on 4G and it even stays on 4G in places that it would always switch and stay on 3G.
Get a new SIM before getting a new phone.

After reading this thread I'm considering switching to either the Thunderbolt or the Revolution, or something else when it comes out...
Anyway, I have experienced this same thing.
The only difference in my situation is that I'm trying to use my LTE internet as a dedicated connection. The setup I'm trying to do is plug my phone into my router and have the router distribute the verizon LTE internet through my apartment. My router currently has the latest version of tomato installed and I compiled my own RNDIS module (modified to work with the charge). Everything works for the first few minutes (15-20), then I notice the 4G icon "stall", then disappear, then reconnect. After the first disconnect and reconnect, the internet connection is very unstable and will disconnect every couple of minutes until I disable and re-enable the internet again... very frustrating.
In the interim, I've been using EasyTether and this works very well. I have streamed hours of 720P video and it works flawless; not one skip or reconnect.
This leads me to believe that it is either one of the following:
The kernel - I'm currently using the PBJT kernel found in the latest version of humble. I'm not sure if the stock rom will provide better stability.
The radio - I currently have the EE4 radio installed, but am very curious to know the stability of the GB radio updates (EP1f, etc.).
Any other ideas would be greatly appreciated!
Thanks!
I am currently running Ninja-0706, radio 26.06.06.30_M.
Intermittantly, my phone will drop out of H and start cycling through all the connections, edge, gsm, 3G etc. After cycling through, it will go to no connection at all where you see "no service" on the screen. And it will stay like that for several minutes, no matter where I am standing in my apartment, or even if i walk outside. Then all of a sudden, it will pick up H, full bars and it will stay like that.
So far, this issue has only happened a couple of times, within the past couple of weeks, and at my apartment. I have full wiped and flashed different roms, and reflashed the radio after the first time this happened, so this issue cannot be blamed on current said rom. This has led me to suspect that maybe there is an issue with the tower in my area. Twice I have called AT&T now about this issue. Both times they claim there have been no outages or issues with the towers in my area. They also claim that the closest tower to me is about 1 mile away, so there shouldn't be issues as such with a tower so close. I don't know anyone in my complex who is on AT&T to see if they are experiencing the same issue. So AT&T seems to think there might be an issue with the phone and i might need to do a warranty exchange. Any ideas before I flash back to stock and exchange it out?
While mine doesn't go that far, it'll cycle between H and 3G for no apparent reason.
Mine does weird **** sometimes, too, on Tue 04_11_M2 radio.
Just today I was sitting around browsing via WiFi, and bam, no signal. Most if the time it'll kick back in after a sec or two, but it stays like that until I intervene by toggling airplane mode, then, it'll be back to 3-4 bars or whatever.
Second time its happened over the last month, so no biggy.
In my house I get lots of signal variations overall, which I guess should be expected.
Well, my phone has done it twice since OP. I just flashed back to stock and downgraded to s-on. I'm going to see about an insurance claim.
Update: Just got off the phone with AT&T. They said that this issue would need to be handled by the warranty dept. So got back on the phone with tech support and they suggested that I go into an AT&T store and have the sim card replaced before they replace the phone, as the sim card itself might be causing this issue. It seems plausible because the sim card is needed for a connection to the network.
Today I went from Houston, TX to Waco, TX and had a strong 3g signal in most places and the occasional lte. However, when I got to Waco, my signal dropped to absolutely no data whatsoever when I would normally have lte. I can call and text just fine, but data is gone. I've done countless reboots, airplane mode toggles, network mode switches, profile/prl updates, but nothing gets data back.
Has this happened to anyone before, or has anyone happened to be around Waco today and have the same thing happen?

I'm experiencing a similar issue in NYC with my data connections dropping constantly. Even though I know my issue is the phone itself as even my wifi will not stay connected. All of my connections may stay on for a few minutes, maybe even a half hour, but then the icon disappears and the connection is gone. Then it will come back, usually within 5 minutes, only to disappear again shortly after.
No clue what's going on, I'm running stock, haven't rooted. I did install the new update recently, but I'm fairly sure it was happening before that, I just assumed it was poor service from the hurricane damage tho.
If it wasn't for your wifi, I'd say it would have been from the hurricane.
The problem for me is that my wifi is fine, and I usually have a great signal is most places in Waco. I usually drop down to 3g in buildings or roam when I go below ground (for a class, etc), but I've never had an entire loss of signal like this. It could be possible Sprint is working on a tower here, but you'd think they'd have more than one tower to govern the data for the entire city.
I think if my data isn't back by tomorrow, I'm visiting a Sprint store to see what's up. Until then, I'm just glad I live on campus and my university has wifi all over the place.

This is not entirely related, but I wanted to throw it in somewhere: yesterday I was in a different city, in a part of town that apparently has a very poor Sprint signal. I put my phone down, and when I picked it up 10 minutes later, it was SUPER hot, hotter than a phone of mine has ever been. It also drained around 15% battery in those 10 minutes! I guess it was from constantly trying to connect to the network, and I don't think it was even 3g.... But I've been in poor service areas and have never seen a phone get that hot before.
Well, I feel stupid. Apparently, when I was turning my GPS off with my toggles, I hit toggle mobile data on accident. Silly me.
