On monday I got my G2 to replace my Samsung Vibrant (due to the Vibrant's GPS issues). I love the G2, but one thing is completely ruining the experience for me. At least two to three times a day my phone is rebooting on me or it will completely freeze where I have to pull the battery. It seems like my problem is kind of common. I was curious is anyone has found any way to fix the random reboots without actually getting a new handset? I just factory reset my phone hoping that it will be a little better and I will update this thread if it gets better. Is there anything else I can try?
One other thing I noticed is that when it randomly reboots it is only a soft reset and doesn't truly reboot. Sometimes after the soft reboot it will hide certain applications like they are not installed until I do a full power cycle reset. Once Angry Birds disappeared until I did a full power cycle and another time it acted like my dialer was deleted off of the phone and I couldn't even make calls until I power cycled. Every time after I power cycle everything shows up so it looks like the media scanning doesn't fully run or something?
I noticed it only does this to me when I have no service...

Well unfortunately I have no service at work. Also, on my way to work I have a small dead zone. It is just very annoying because it happens 2-3 times a day.

I have the same problem with signal loss (although my phone does not reboot, I just have to reboot to get signal back), only at home and on the way to work. I put my phone on 2G only at home (since signal sucks, not giving anything up) and on the ride (again, not using the phone for data so not giving anything up) and I don't have the signal loss problem at all.
Have you tried 2G only?
Throw your phone into 2 g. This should fix alot of reboot problems and signal drops. It fixed mine. I had the exact same problem after 27 hrs. Take it outta 2g if you know you'll be in a high speed network.

I'll try 2g over the weekend and see how it is. Thanks for the suggestion.

I heard to turn off the backup data and that gonna stop the reboot, I did it, and no more reboot for my g2
I sent both of my G2s back because of this issue. IMO "switch to 2G" is not really an acceptable fix... hopefully HTC issues an OTA for this soon.
Though I do not have this problem myself... Two things I have seen people try that helped:
Make sure you are using a new SIM card, and try a better quality Micro SD card than what comes with the G2. You never know...
Hope it helps.

Thanks to everyone who replied with suggestions. I seemed to have fixed my reboot problems by turning off the application backup feature. I am still using 3g data so far with no reboots or freezes in the past 24 hours. I have driven though my bad signal area that usually causes my issues at least 4 times so I am pretty sure it is fixed. If anyone else has turned off 3g data try turning it back on, but turn off application backup and let us know how it works for you.

Hey guys,
This is actually my first post here but I do A LOT of reading on this forum.
I didn't quite find anything regarding my question (or at least a solid answer), however, so I've decided to post it up.
Has anyone else experienced a sudden loss of data from time to time out of nowhere?
I go from having Full Green 3G bars to grey bars out of the blue. I've heard the green bars is to let you know that you are connected to Google services but I am not able to access anything that uses data.
For instance, when I open up the browser, I receive an error telling me there is no network connection. When I open up anything else that uses a data connection, Market, News, etc, I receive the same error about there not being a connection.
This would make sense if I was moving and going in and out of service areas, but it happens when the phone is simply sitting on my desk and not moving at all. I usually use it to listen to Pandora while at work and have noticed that the songs cut in and out due to this sudden loss of a data connection.
I went from a Nexus One to the Nexus S and have never, not once, lost my full 3G bars in this same exact location. I personally believe its a software bug of some kind and have high hopes for it being fixed in the future. The N1 had similar issues when it first launched and Google / T-Mo were able to remedy that for the most part.
I am actually on my third Nexus S because the first two had some type of hardware issue; the first one's back button didn't work or light up and the second one had a blown ear speaker and would sound like a blown speaker in a car. As an early adopter, I expected this, so it didn't bother me in the least bit.
ALL of them did the same thing, so I know it is not just limited to my exact phone. This is definitely something with the Nexus S in general (or the current build of Gingerbread).
Can anyone shine some light on this situation? Thanks in advance and keep up the great work here guys!
---------------------------------------------------------------
UPDATE: Here are a few steps that I have taken in order to solve my sudden loss of data issue. I'm not guaranteeing this will work for you, but it has worked for me and a couple of users here on the forum.
Do the following:
Activate / Use the Sim Card that came with the phone (this is to ensure you are using the latest sim cards)
Make sure you have a 4G internet plan. (No t-zones, No web2go -- FULL internet only)
Call T-Mobile and have ask them to Reset your phone with their Towers
Here's a more technical explanation posted by Johoja:
1) Having network selection set to manual ( i.e selecting 302490 or TMOBILE) will result in No Service on a reboot. Solutions: - Have to cycle airplane mode to get it to pick up service (can be done with automatically tasker) - OR Use automatic network selection. (you can force wcdma only but that will reset the SMSC which is annoying if you go in and out of wind away/home areas and you want to roam.)
2) Being in a area with no service for extended periods of time 5+minutes(subway, basement, etc) will result in a dead baseband, meaning once you come into an area with service the phone will not reacquire signal, airplane mode will not work as the baseband is now crashed, cant maunally search for a network. Have to reboot to get signal. Solutions: -Use tasker to cycle airplane mode on and off when in no service areas i.e) search signal 4 minutes, airplane mode on 10 minutes. This will keep the baseband from crashing and possibly save battery. -Use NoBars to accomplish thesamething ( taskergivesyou a bitmore flexibilty of course but harder to use) http://www.appbrain.com/app/nobars-b...omdryer.nobars - Use airplane edit to avoid turning wifi/bt off when airplane mode is on. http://www.appbrain.com/app/airplane...kalti.airplane
3) WCDMA perferred does not work. - No solution
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=747f398a6c1bb2b9&hl=en&start=40:
I read one users response on a different thread regarding something similar to the issue that I am having.
They said T-Mobile told them to get a newer sim card and that this may remedy the problem. In my case, this has been the only constant in the 3 phones that I have been through. I have had the same sim card for about 3 years or so now.
I will try activating the sim card that came in the box with T-Mo to see if this remedies the problem. Since I'm at work right now I will have to try when I get home later.
Does anyone think this will have any affect what-so-ever?
The galaxy s phones when first released, all variants, had issues of signal dropping from full to zero bars while sitting in one place. I remember because there were YouTube videos of it All over and it was shortly after the apple antenna issue.
Not sure if or how it was ever resolved. But it seems that Samsung may just have this type of radio baseband performance if we see all these individual units doing this. I don't know maybe others can respond.
I have the same issue as the OP. I travel to the same location weekly with NEXUS ONE, signal never drops in the T-MO Country here locally, and streaming CNET POD CAST never a hiccup, however, with the new NEXUS S, I would lose DATA Connection only, while the 3G will show full signal. I had to reboot the phone to get the DATA back.
is it the S issue or 2.3 issue?
food for though....
If you have T-zones or Web2go or Phones 1st web, you will have problems
I had the same problem too, now I fixed the problem. The thing was that had the wrong data plan on the NS, i had my old web plan from my hd2 which seems like different from the one for the NS. I restarted my phone after 5 mins off and now i have my internet working beautifly. A T-Mobile rep said that it was an error in the system that made the phone think that that was the right plan for the NS for a few. A glitch you may say, but all you have to do is put the right data plan that all, easy. Hope this helped and have a wonderful holidays everyone.

this is happening to me too, last night for a little while and today for about hte last 4 hours can't get connection back. i have full white bars, with 3g icon but can't access anything
So I activated the new sim card last night and I'm still having the same problem. Albeit it doesn't happen as frequent, but it still does it nonetheless.
I will call T-mo again to verify my plan. I am on a 1500 Minute Family Plan which includes unlimited data and messages. I will see if they need to tweak something and let you guys know if this remedies the problem.
Ok, it seems like the issue has been resolved after I spoke to T-Mobile earlier today.
The rep on the phone verified that the data plan I was on was in fact the correct one. He said he was going to reset the signal from the towers to my phone to see if this would resolve the issue. He asked me to turn my phone off for about 15 seconds after we hung up.
Since then, I haven't seen the problem arise again so my guess is that it somehow fixed whatever was going on.
I'll let you guys know if this changes and the problem occurs again.

What's with the CAPS? ?
On topic: i have a captivate and I can confirm that all galaxy S phones had droppend data. An official ota update fixes it so maybe you guys need to wait for something official. Isn't there a new firmware for the nexus S already? Try flashing that and see if you still have issues.

Doesn't every android phone from samsung have this problem?
I know the Moment has that problem, after 3 updates samsung called it quits, I still have to reboot mine 2 to 3 times a day for data lockups.
@timur525 Yea, I'm already on 2.3.1.
I manually updated the first hour it came out hoping that it would solve the issue. The problem was still there after the update.

That shouldn't affect anything. My number shows up in status.
I had this issue resolved a few months ago as the push-to-talk app Tikl requires this in order to use it.
I was having the problem even with my number showing up. Call T-Mobile and have them reset you with the towers like they did for me and see if that helps you too.

I posted about this same issue on wrong section of the forum. Ive had this issue ever since samsung vibrant. I have applanet installed on my phone and some of the app that i installed accessed my apn and totally changed my apn setting to "Sirious application disabled.epc.tmobile" or something like that so i wyped everthing off from the phone and so far i havent had the issue ever since yesterday. Also i had the locale and language setting to korean so im thinking that might be causing it also.

That's what I remember too. I think its just an issue with the radio Samsung uses in all their phones. Might not be a way to fix it if even their new phones like the nexus s still have this issue. They prob would have tweakdd it by now if they could.
Same problem here. Xmas eve on shift and I have a phone that had no connection whatsoever (not even phone capabilities) this may be the one thing that takes the phone back. (If it happens again)

Have you called T-Mobile to see if they can give you a reset to the towers?
I had this done yesterday afternoon and haven't had the problem again since.
Also, if you'really using an old sim, I would suggest activating the one the phone came with just to be on the safe side.
If that doesn't help you then I would at least wait until just before your return period ends to see if there will be an update to address the issue.

I am running .588 and I restored my data after coming from the original gb (.573) leak. I loose my 3g connection at least once a day. Sometime when I toggle the airplane mode it works and I connect back to 3g, but i that does not work I just reboot the phone. Anyone else having this issue? We need feedback to see if its a hardware or software issue in gb. The reason I cannot confirm if it is s/w or h/w issue I received a replacement phone when the .588 came out. I cannot compare both builds with same device. I am going to revert to .573 to see if it continues. I will post back with outcome.
Thanks in advance

The airplane mode does not work for me. Someone recommended to use an app called signal refresh. My main concern is if its a s/w of h/w.

I have this problem, as well. I used the Monster SBF to get to .340, installed GB, and restored only user apps with Titatium Backup. Airplane mode works for me sometimes. Every now and then my phone will go into airplane mode and lock up, forcing me to do a battery pull...
I was on the old gb leak and restored data in clockwork after moving to the new gb. I haven't had the problem yet today. (Knock on wood)

Same
I'm seeing the 3G drop as well. Of course i only notice it since i'm tethering my wifi xoom to the droid (method irrelevant). Airplane mode works for me.
Mine drops out and stays out all the damn time. Sometimes airplane toggling is enough, sometimes I have to re-boot the phone and then toggle airplane mode and other times just turning WiFi off works well enough. It happens on my Wife's D2 constantly as well. We've missed plenty of calls (google voice pops up letting me know I have messages from missed calls even though the phone didn't ring and we have big problems texting throughout the day).
We're both going back to Liberty right now cuz this is BS. Hopefully this will get fleshed out for the final OTA and I can see why Verizon hasn't approved either leak yet. And even more hopefully it's not the new radio, and if it is hopefully SBF-ing back to 340 will fix it. If it doesn't, do any of the older SBF's work with the 340/588 bootloaders and also contain older radio firmware?

Update:
re-flashed GB. went two days with no signal problems, but this morning I lost my 3g connection. I have a feeling that it has to do with the hand-off between the wifi and 3g connection. I have tried to duplicate the issue but I cannot duplicate it. Also one thing I notice is when my 3g is not working and only shows the 4 grey bars I cannot make outgoing calls but calls do come in. Weird....

has anyone noticed when this happens that your 3g icon and the signal bars go from blue to a white/grayish color? i have to reboot mine eveytime and then it works perfectly fine for another few days.....
Mine do that, but they turn blue one I starting using data
This is my 3rd Sprint S4 over the past few months. All of the devices are loosing the 3g icon but will show bars. Voice and text works fine, data and 4g does not, i have noticed it usually happens when i leave a WiFi area and it has trouble switching back over to cell data. I can reboot the phone and about 80% of the times it will return to normal. I have used odin to reload to factory. I had my phone rooted only and recently install the Triforce rom to see if it was a software or Kernel issue. Same thing is happening on that rom as well. It doesnt matter where i am so i dont beleive its a tower issue. Any idea?
This happens to me as well. Just Sprint being crappy. Try turning airplane mode on and off, same effect as a reboot but faster.
I tried the airplane mode toggle but didnt seem to fix it. If i use even the "Hot reboot" option in triforce rom that doesnt fix it either.
Assuming this this is the same issue I always experience, there is no fix. It's a network thing. Is there 4G in your area?
What happens to me is my phone will be on 3G, then start receiving 4G, but it doesn't recognize that the data service is now different, so nothing works for 15+ minutes or until I toggle airplane mode on/off.
I take it you've tried just turning WiFi off?
Haha, yea, welcome to Sprint. Enjoy losing data when it's least convenient (such as when you need to use navigation or missed your exit and need to be rerouted). Oh well, the price we pay for unlimited data, right?
I have noticed the same thing since I activated my LTE radio. LTE is expanding in my area so I constantly go in and out of 3G and LTE service. Sometimes when this happens data just ****ing stops working until I enter airplane mode and then come back out of it (a reset works as well). For some reason (or it is just a coincidence) The problem has amplified since installing 4.3. Has anyone else noticed an increase in this problem since upgrading? This is absolutely a Sprint problem? Do we know that people have this same issue with other Sprint phones?
I have the same problem. From wifi to f data takes a little bit of time for it to switch over especially since the data toggle is gone with the 4.3 update. Unlimited plan is water downed from my experience compared to tmoblie. But tmoblie service was horrible.

Well Sprint's speed has always been an issue for most of us. That is no surprise. I at least expect to to work AT ALL which apparently it is incapable of doing recently.

If wifi is on 3g/4g is not there,, turn off wifi and you should see icon,, if you see bars it's most likely working :sly:
Edit just re read your post, I have the same issues sometimes and as posted above toggling on and off typical works for me,, good luck
Also is your network set to

Seems like a hardware problem based on your description. I am fully convinced that this whole flashing modems things is just a feel-good measure for people who have exhausted all other options. It was big in the Galaxy S2 days, but I have never seen any measurable difference between modems in any meaningful metric on that device. At least not one that could not be attributed to other factors such as signal quality and network load, and nothing consistent. A different modem isn't going to fix a hardware fault or magically improve Sprint's awful service.
I have a problem with my 6p where the signal just drops to nothing (Looking for service) and 3 or 4 seconds later it reconnects to a good LTE connection. The problem is not my connection as I live in a good area. I was rooted with xposed but for ****s and giggles I went back to complete stock and it is still happening.
I have reset the APN settings to no avail. Is this a thing that is known to this phone? Should I get a replacement? It started just recently it seems as I have had this phone since launch.
What sucks is, is that this phone is absolutely perfect (or was) and I dont want to get sent a phone with screen issues.
EDIT: I ended up getting an RMA and everything is hunky-dory.

Did you ever find a remedy for this problem? I'm having the same issues on t-mobile so its definitely not network or a similar related issue. Did flashing the radio from the 6.0.0 rom fix the issue? I already tried several different 6.0.1 radios and a radio from 7.0 but to no avail. I'm about to try it and if it doesn't work I'm getting rid of this phone.
I'm going to assume you mean you'll be on LTE for the longest time then all of a sudden signal completely drops then comes back on, but without the LTE signal showing near the bars, so you'll have to airplane mode, then switch mobile data on and off, then do a restart. If this is the case. That has been a documented CM13 issue for the longest time. I had the same issue with the HTC M8...

I am on LTE but as the OP said the signal randomly drops completely for 4-5 seconds them comes back LTE and all. I don't have to reboot or anything. This doesn't have to do with cm13 though, I've tried flashing back to full stock and I still have the problem there too.
