We're trying to determine the "root" (pun intended) of the problem so if you wanna come in here and start a fight go find a local bar to do so. We need to try and locate the source of the problem so either post something useful or walk away.

There seems to be some confusion and I dont know if its being ignored or what but theres an issue with these kernels that needs to be looked into further before new ones continue to be released.

Theres an obvious problem for a good amount of people and everytime I look I see comments that there isnt a problem. So heres everything I could quickly find regarding it.

Now Im not trying to be a **** about this but I dont get how the issue is unheard of when its one of the biggest topics in this section. And so we're clear, this is happening in ALL kernels. Unfortunately its been more profound in Zedos because it seems more people went with his method.

All Im asking is before more and more kernels are released that someone at least acknowledge the problem and see if it can be addressed before more and more people root and start complaining because they were told there was no LO.S. bug

Telling you right now someone is going to come in here and go "this belongs in General" then a mod will move your thread and deduct 5 points from something, not sure...but just a heads up
[Samsung Epic 4G Touch] dutchman71:
I also see a lot of people having issues, but I'm now on day 2 of flashing Zedo V1 and have yet to experience any of these issues. Not sure what I did different, but everything just works... The only thing I did was after rooting was getting my MSL from Sprint and erased the proxy servers in the ##3282 menu.

EDIT: Ok, I just lost service 1 1/2 day after rooting... Bug finally hit me..
[Samsung Epic 4G Touch] wingzfan:
I dont mind it being moved and I have no clue what the deduction in "points" does but I'll deal with it.

Now Im getting much better battery but I know people are still losing service on the new OC kernel. My roommate happens to be on e the unlucky ones.
[Samsung Epic 4G Touch] plmiller0905:
Man...thanks for posting this. Hopefully the mod doesn't close this thread. This definitely is a concern and a serious matter. I don't care if these kernels are, "use at your own risk" these kernels should've been listed as betas, and/or the bugs should've been listed and further testing should have been. If those steps were taken, I bet a lot of people would've held back from flashing them. I know I would have.

Shabby posted this earlier in the other thread (post 160):

http://xdaforums.com/showthread.php?t=1267762&page=16

One thing that got to me was this morning I woke up, hoping to see a stock kernel and/or a way to return to stock. And instead, I see a new overclockable kernel. To me that's just not right. I think that you have to prioritize. That's like putting out a rom that has all data broke. Then instead of fixing it, you put out another rom...while disregarding the issues with the first rom. At least acknowledge the issue and let everyone know it's been worked on....don't just blow it off.

I know some of the devs over in the Evo forums was good about this....if something went haywire with one of their roms or mods...they were all on top of it to get the issue fixed and they also communicated with posting updates on the matter.

Like I said, hopefully the mods don't close this.

I'm definately gonna follow this thread...thanks Wingzfan
[Samsung Epic 4G Touch] superhtchd2:
i rooted yesterday using zedomax method, did the OC kernel last night.. havent had any issues so far ..
[Samsung Epic 4G Touch] wingzfan:
Bubby does have the stock kernel pulled. I was testing it till 1:30 in the morning but he's gotta recompile it. It was bootlooping so today thats his first order of business.

As for the kernels, I flashed it by choice. I dont blame the devs for ANYTHING, Im just saying acknowledge theres a bug and lets see how to resolve it.
[Samsung Epic 4G Touch] OrygunGal:
I've been reading through the rooted kernel threads as well prior to jumping on the root wagon and have seen several people mention that they are not rooted and have experienced the loss of service so it seems that the issue may not be exclusive to the rooted kernels...possibly a Samsung bug?
[Samsung Epic 4G Touch] wingzfan:
Very possible which is why im hoping we can get an idea of how man people are rooted vs non rooted having it. Now the only thing is I cant find any complaints online about nonrooted phones doing it except a few here and youd think it'd be widely discussed

Sent from a Galaxy far far away...
[Samsung Epic 4G Touch] plmiller0905:
Yeah...I read those too. However, I never lost any service at home with any android phone I've owned..Nexus S 4g, all Evo's, Epics etc. Then today I wake up and I have no service....maybe it is a samsung bug, but I'd rather return to stock myself to see if the issue was still there.
[Samsung Epic 4G Touch] wingzfan:
Stocks on its way i promise. Probly tonight actually. Bubby was really close last night. Once we get that Id be curious to see what happens.

[Samsung Epic 4G Touch] plmiller0905:
Sounds good...can't wait
[Samsung Epic 4G Touch] joetemp75:
This is an issue that started with mine also yesterday. But not only did I lose data but gps also. A reboot fixed it but I would like to know whats going on. I just came from the evo 3d and there was an issue that had to do with the prl so I am going to give that a shot with the 11115 prl that fixed the evo. Will post back with the results later today.
[Samsung Epic 4G Touch] volwrath:
On V5, Ive only had the loss of data once in about 12 hours, versus about 3 times on Zedo V1.

I also did http://xdaforums.com/showpost.php?p=17703908&postcount=11 for the hell of it to see if that helped (even though I got it at a sprint store)
[Samsung Epic 4G Touch] dmarden:
For the record:

A) People have reported this issue even on the stock kernel. It is not clear where the cause is.

B) For kicks (and because it cannot hurt) I did the whole profile/PRL update thing that someone suggested. Be it luck or real benefit, I have no had the issue since.
[Samsung Epic 4G Touch] OrygunGal:
I would think it would be widely discussed as well so that seems odd. I'm waiting to see what evolves or at least for stock kernel (an undo) before flashing a rooted one. I don't have TEP.
[Samsung Epic 4G Touch] dmarden:
It's still a bit early for the issue to be too widely discussed.
[Samsung Epic 4G Touch] OrygunGal:
Nice. I was told by a helpful Sprint cust. serv. rep. a while back that you should update your PRL & Profile when you go into a new area (tavel, move, or even long commute to work) regardless of which phone you have. I would think unboxing your phone would qualify as well. It sure couldn't hurt.

---------- Post added at 06:59 AM ---------- Previous post was at 06:53 AM ----------

Good point. Many people would not likely research on the web/forums, instead they'd likely address the issue directly with Sprint.
[Samsung Epic 4G Touch] MadFlava:
Ever owned a Samsung phone before?

This is my 3rd one and I swore after the last one Id never buy a Samsung phone again but I got sucked back in. Samsung is notorious for shipping phones with all kinds of bugs that should be considered showstoppers then pushing out fixes months later.

It would not surprise me at all if that was the case here. I am one of the ones having this issue and I am not rooted. Ive lost data several times after hanging up a call. The data never restores and I have to toggle 3G to get it come back.

I dont think this is a kernel issue. I think its something to do with the rest of the OS, either that or the kernel is a different problem thats just acting the same way.
[Samsung Epic 4G Touch] wingzfan:
Ok thats what i was hoping to find is nonrooted and rooted people who are having the issue. Now on my moment this issue was huge so i went to htc and maybe thats the case again. Maybe sammy dropped the ball again. Question is what can be done about it.

[Samsung Epic 4G Touch] gpgorbosjr:
Just for the record:

I am coming from a Thunderbolt on Verizon. I switched to the Photon which I liked a lot, but bought the Epic Touch because my Photon would not receive texts/emails at points, or calls wouldn't go through. And on top of that there was no development, so I switched.

Now, I haven't confirmed it but I am pretty sure that some of the same things have been happening on my Epic Touch (not rooted).

My point? I think it could partially just be Sprint. I had Sprint before/after Verizon and it is no where near as reliable, and in my latest experience either the Photon/Epic Touch have serious bugs, or Sprint's network is killing me.

If I used my phone half as much as I used to I'd just switch back to Verizon. But I don't use it as much now and would rather save the $ and miss a few texts/calls.
[Samsung Epic 4G Touch] clamknuckle:
I had it happen to me after rooting. The Network isn't going to cause your phone to force close and the circle with a strikeout sign show up until after you reboot.

If it was the network, it wouldn't work at all.
[Samsung Epic 4G Touch] EJayMz:
Same here
[Samsung Epic 4G Touch] OrygunGal:
You may have something here but it seems to me that if it were Sprint's network, people would not need to reboot their phone to get service back. I could be wrong...
[Samsung Epic 4G Touch] gpgorbosjr:
Well I haven't needed to reboot my Samsung yet (although I think some texts went missing and I have) but when I had the Photon it would say I had a signal yet texts/data would randomly get stuck into I rebooted or sometimes airplane mode on/off would work.
[Samsung Epic 4G Touch] musclehead84:
I have not rooted either. Waiting on a stock kernel to come up. I use wifi all the time on my phones at home. I leave it connected to my home wifi whenever I am home. Thus is the first phone that is unable to maintain a constant wifi connection. When the phone goes to sleep a while and I wake it up it says I'm connected but I have no Internet. And this is the second epic touch to do this. My hero, evo, and epic never did this.
[Samsung Epic 4G Touch] svennn:
I just had data drop on my E4GT while sitting at my desk. Stock, non rooted. I never had it happen with my Evo in the last year.

I'm going with a Samsung issue on this one.

[Samsung Epic 4G Touch] Steady Hawkin:
Are the people who are having data and service loss also experiencing issues with moderate battery drain???
[Samsung Epic 4G Touch] wingzfan:
My buddy is definitely draining quicker than stock but thats probably a seperate issue. Now myself I feel am draining faster as well but my use is pretty sporadic and hard to determine. It feels like its faster but then again I feel like I cant leave the phone alone.
[Samsung Epic 4G Touch] clamknuckle:
Apparently the battery drain issue is a known one and they have fixed it a custom rom for the international GSII.

The suspend process is broken or something. I'm hoping it's fixed in a custom rom for ours soon.

Its odd too because it doesn't always break, just sometimes.
[Samsung Epic 4G Touch] nobrakes:
I had the circle for signal happen to me one time before I rooted. Luckily I haven't had it happened since I've rooted. Bought mine from a Sprint store.
[Samsung Epic 4G Touch] tdavis42:
I'm gonna laugh once stock gets released and all you complainers still have problems. If you can't handle some bugs and kinks then go to androidcentral forums where all the old men complain.
[Samsung Epic 4G Touch] wingzfan:
Good info, Thanks.

That may explain why before root I was getting 18+ hours on above average use and now I may get significantly less.
[Samsung Epic 4G Touch] plmiller0905:
I hope that u don't get in a tough situation and have to make a call only to look down and see you have no service.

Bit on a serious note, I just stopped by the sprint store. The Rep I spoke said that he's been having the same issues as well...as far as the phone going to no service and all.

He said that sprint is in the process of updating their towers in my area and reassured me that its not the phone.

So I'm gonna stop my complaining and enjoy the ride. If something goes wrong ..that's what TEP is for...

:-)
[Samsung Epic 4G Touch] Pitnefor:
it'd be helpful to have a experimental section because the current development going on (without a full restore option) is very risky.
[Samsung Epic 4G Touch] wingzfan:
Heres an idea...Read the purpose of the thread. Its to help determine if this is a root issue or a samsung issue as well as seeing if we can get to the bottom of it and resolve it before it gets out of hand.
[Samsung Epic 4G Touch] Steady Hawkin:
Here is what I have noticed:

-Since updating PRL I have not had the los issue, what I have noticed is data seems to just stop

-I went to bed last night with 93% battery and woke up this morning with 61% battery. Battery seems to be draining fairly quickly

(*Rooted and running Z's 1600 kernel. Had the same issues before as well*)
[Samsung Epic 4G Touch] wingzfan:
Ok as for the battery drain. I went to bed at 99 and woke up at 93. Since then Ive used my phone pretty heavy and Im at 75. I started using it at 8 so 3 hours ago.

18% in 3 hours isnt horrible for actually using it. At that rate Id get 16 hours.

update: You were draining that quick on stock?
[Samsung Epic 4G Touch] tdavis42:
Here's an idea.
[Samsung Epic 4G Touch] Erislover:
The people saying that it can't be the network's fault are not necessarily right. It is possible, after all, that the network targets particular phones (individually or in groups) and disconnects their cell service, which is undone through a radio reset (either reset of phone or toggle of 3g services).

Also possible is that the network isn't to blame, but sprint still is. Perhaps a sprint app or some background sprint process is the culprit. Removing bloatware - if done correctly and fully - may be a way of testing this theory.

---------- Post added at 11:43 AM ---------- Previous post was at 11:39 AM ----------

Are they updating their towers all across the country? Because we're all having the problems...

And if they are updating all their towers, when will the updating be completed? 2013? Will we have dodgy signal until then?

Cellphone reps - with the exception of those here - generally know very little about anything except the commission they make per sale. Harsh statement, I know, but borne out by years and years of experience...
[Samsung Epic 4G Touch] joetemp75:
I was on the evo 3d last week and spring releases a prl that forced everyone to 1x so this may be similar. I changed my prl to the 11115 one and so far so good. It has only been an hour but here's to hoping
[Samsung Epic 4G Touch] Silent25r:
Try resetting the PRL. Worked for me. My phone hasn't froze or lost data and voice. It use to do this once a hour or two for me.
[Samsung Epic 4G Touch] plmiller0905:
Yeah I did that as well.

I also flashed the latest zedomax kernel about 4 hours ago to give it a try.

So far all is good. I will report back later this evening.
[Samsung Epic 4G Touch] joetemp75:
Just lost it again after doing everything in this thread. It is something beyond just the network imo
[Samsung Epic 4G Touch] wingzfan:
So its not reconnecting to the towers after a call. Fanfrickintastic
[Samsung Epic 4G Touch] chaoswarp:
@Calkulin Wow yes totally confirm this does cause LOS but my service does return on its own. Which does not happen when i get hit by the bug.
[Samsung Epic 4G Touch] wingzfan:
Personally I think its the same crap that went on with the moment, transform and epic. Data locks/signal loss. If this turns out to be the case Ill grab the photon. Ive gone thru this crap before with sammy phones and wont do it again.
[Samsung Epic 4G Touch] MadFlava:
I suspect you are right and god knows how long its going to take Samsung to address this. It really sucks that Samsung and Sprint continue to pull this crap. Every single Samsung phone that comes out has deal breaking bugs that take forever to get resolved.
[Samsung Epic 4G Touch] abowlby:
I see what you did there. Still, if I could keep my phone as is, kernel and all + root, I would be gladz.
[Samsung Epic 4G Touch] MadFlava:
Perhaps we should pull Engadget into this and get a story posted to try to get Samsung's attention.
[Samsung Epic 4G Touch] plmiller0905:
Well...so far mine hasn't lost any data since flashing the oc kernel and resetting the data.

And I haven't had any issues with GPS either...I get a lock rather quickly.
[Samsung Epic 4G Touch] Scaplet:
Odd, this never happens on mine. I am on wifi all day at home and all night at work, wifi is always available on wakeup. Fact is, I haven't had one issue whatsoever; wifi, gps, bluetooth, and 4g. I've used all of these in many places to multiple devices.

This is just like, my opinion man.

I odined Z's 1600 last night and after an hour i started losing signal and battery. I did a prl update and set my speed to 1504/400 and i havent had a problem yet. my battery is better, still not great, but I'm a heavy user. After the prl update, i still lost signal till I chamged the speed with setCPU. Don't know if it's a fix, but ot worked for me.

Edit: as for sprint's attention, thats a guy in a retail store, not a tech on that post
[Samsung Epic 4G Touch] JOHNGAETANO:
Before my root, I had two loss of signals over the weekend in areas that have perfect coverage. I blew them off. I also am having a hard time maintaining a WiFi signal, or connecting at work. This is odd, as every phone, tablet, etc.. I have tried to connect to this WiFi works perfectly.

After I rooted yesterday, I noticed the same poor WiFi issues, and I got a loss signal this morning. A reset solved the loss of signal issue. The WiFi issue remains.

Something is wrong with the network, or the phone. I doubt it's the root.

[Samsung Epic 4G Touch] runner77:
Can you point me to where I can find step by step instructions on resetting the data? Without having to call Sprint. TIA.
[Samsung Epic 4G Touch] THAD LOVELACE:
I had the exact thing. problems with the zedomax kernel, all good after the flash of the OC Last Night!
[Samsung Epic 4G Touch] plmiller0905:
I could be wrong..but like i said in my earlier post, sprint in supposedly working on updating its towers. If that's the case, maybe that's why some people have the issue and some don't...and that's why it's happening to people that's both rooted and non-rooted.
[Samsung Epic 4G Touch] Vegasden:
I think you may be right to certain degree. My only data issue was when I first got the phone on release day. Sprint Tech support initially told me my loss of data was tower problems. Eventually we reactivated the phone and I've had no issues since.

Using Tasker, I had did a scan for "cell nearby" a few days ago. 2 towers showed where I previously had gotten 3. Today, in a new scan, a 3rd tower showed (one I knew was closest to my home) but the original 2 that appeared in my first scan did not register.

I know Sprint has a big infrastructure announcement in a few weeks. Perhaps they are converting towers in advance, thus creating issues now as towers go off line for whatever work they are doing.

....
[Samsung Epic 4G Touch] Dalmus:
On the Moment, the issue was eliminated when devs got Android 2.2 onto the phone. I haven't had a radio lock since January.

That leads me to believe it was an issue buried in the kernel somewhere.
[Samsung Epic 4G Touch] clubtech:
I tried the solution posted here on my rooted Epic and so far so good.

Before i was dropping signal and losing signal completely very often.
[Samsung Epic 4G Touch] MadFlava:
If youre really in Wisconsin, you're so far away from me that they could take all your towers down and it would still make no difference to me whatsoever. Plus my OG Evo worked fine without this signal dropping crap.
[Samsung Epic 4G Touch] xenide:
I had the issue on v1 of zedo's kernel as well as v5 of shabby's pre-rooted kernel.

However in v1 of zedo's the problem was much more pronounced. It would happen regularly about 30 minutes after making a call, without fail. With v5 I've only had it happen once in about a day. Also in v1 of zedo's kernel the dialer itself would freeze if I tried to call after waiting for about 10 minutes after a call, not sure if this is related at all.

Haven't tried any of the proposed fixes yet, going to try flashing zedo's OC'ed kernel. If it happens in that I'll try some of the fixes and if that does nothing I'll try bubby's CWM kernel.

RE: No Signal issue::::

I am *NOT* rooted.

BUT,

I get the no signal issue. The only fix is to reboot the phone or put it in airplane mode and kick back out.

I am wondering if this is a native kernel issue that stems back to Samsung them selves.

Again, this phone is 100% stock. Its happened 3 times now, and its a real pain in the ass. Still love the phone more than my previous two generations of Evo's.
[Samsung Epic 4G Touch] xenide:
The airplane mode thing doesn't work for me, but I am rooted.
[Samsung Epic 4G Touch] wingzfan:
Update:

Root is not the cause off the Loss of Service

I exchanged mine and my roommates phones today that were rooted. He had the LOS bug and I didnt. We both said F rooting for now and were gonna stay stock. We actually argued about it being the root.

His just LOS'd and needed a reboot to come back so its not the fricking root
[Samsung Epic 4G Touch] mcflargen:
It was a different issue Wingz. The phone decided randomly send and/or not send text messages. I was able to make a call. Definately not as horrible as it was the past 2 days. The 3g and signal bars were there still.

PRL update and all seems fine. I haven't had a chance to really use the phone since I was at work all day. The battery is astonishing again, im thrilled.

~T
[Samsung Epic 4G Touch] dionnow:
.

I rooted via zedomax's method within an hour of activating the phone, and have had LOS service pretty consistently since. Two hours ago, it would LOS nearly immediately upon reboot. A couple times it would turn on and 3g wouldnt enable at all. After 5 consecutive reboots 3g data began working again, until the next LOS.

Its also notable that MSL updates would fail with the error: no data connection even when the 3g was working for a moment. Profile updates were successful every time as long as the 3g connection was active.

I reset the scrtn, or whatever you call that process, about 75 minutes ago and have not experienced the LOS yet. I'll update this post when/if it does.
[Samsung Epic 4G Touch] Pheno.menon:
Lots of data drops today, had to restart phone at least 4-5 times.

On the topic of it being a root or non-root issue, I'm not sure because I rooted as soon as there was root.

I rooted with Zedomax and am having the same issue as well. I will usually need to reboot to get the radio working to make and receive calls. As for the 3g, it permanently does not work for me but 4g does work which is strange.
