Loss of network - Samsung Epic 4G Touch

My issue is whenever I hook up to wifi my mobile network drops not allowing me to make phone calls. This ask started once I rooted my phone. I'm running the stock rom as well. The only solution is for me to reboot my phone. Is there anyone else having this issue, and is there a solution?

Just doin to the stock Rom. It fixed los for me. And it updates your radio

FYI OP, this is all over the place under LOS, or Loss Of Service.
These issues haven't had one guaranteed fix (or any reproducible permanent fix that I have seen.)
Reported LOS occurs in low signal/roaming situations, when wifi is on, or unbeknownst completely... all these depending on the user, and solutions are equally thin and subjective.
Most likely there is no current fix for your issue until an official update occurs. Until then you can probably try to placebo the problem away like most people here.
... and your other issue can be solved here

Should we start calling this "LON" now? Lol

Loss of Network is what occurs when someone ditches Sprint for a phone that comes out on another carrier that isn't broken (which in this case is a fairly substantial sort of broken for any regular user) from day 1 and counting...
We XDA lurkers/trolls/devs, we are the ones that stick, for better or worse, until that update comes out that makes the phone function... a phone whose modems are working 100% of the time for the major reason we bought it, to use as a phone, with signal and data and the like.

LON is a new problem now so we can start another slew of threads about it.

Okay, I didn't know what los stood for, but I appreciate all the help. Now I know. I'm glad it wasn't something with my phone.

There's a glitch with the e4gt that I think was the issue with Los

Ok so whenever I reset my ram with task manager my radio crashes and when it comes back on it says roaming then jumps back to Sprint service. It also happens when using ##3282# wether I go to edit or view clicking on evdo will crash the radio. It did this on every build since I got the phone. Its nothing major like b4 when rebooting was the only way to get back in service. Just wanted to point it out bcuz I know its not normal and never experienced it with the og epic.

Its not a glitch that is supposed to happen. When u clear the RAM it stops all apps and processes from running. That us why that happens. Actually that was used to help get rid of LOS rather than rebooting cause it resets the radio.

Ok but why does it do it when accessing ##3282# and clicking on evdo from both the edit and view option? Also mind you it did this on my EG30 firmware when I got the phone. I disagree for the simple fact my phone always did this from day one. Clearing my ram always crashed my radio on eg30 so how is that new? Don't get me wrong I believe they did find a way for the phone to not have to reboot when it happens, but that right there is not it. Its a hardware flaw..

Also let me point out that my og epic used the same task manager and clearing out my ram would not crash my radio.

+1....clearing ram does not crash my radio
sent from the near past
Clearing apps and ram from the built in task manager does not, and never has, crashed the radio on my phone.
Did any of you two that never had this happen ever had a LOS occur before the fix? I'm no pro at being a super geek but I know when something seems screwy with my electronics...

I got my phone about three months ago approximately. It must of had eg baseband on it because it immediately updated to ek02. I don't know if what I think Los is, is actually what it is. I thought it was, when you woke up the phone, you would discover that the 3g and bars were gone and replaced with a circle with a slash through it. Am I mistaken?

Your radio will always reset after ##3282#.. It resets to apply any changes. Just the same as after a profile or prl update.
But should not after clearing apps in task manager.

No the heck it shouldn't! I'm not even applying any changes! All it takes is for me to click evdo from whichever option wether edit or view. Mind you my screen freezes fir a short min when I do go to the evdo setting. Maybe I should make a video bcuz i'm tired of people saying this is normal. I bet the people who said they radios do not crash when they clear the ram won't experience this issue. If this is normal why the same option on my og epic which I still have doesn't do this screwy behavior?

Ok that's good to know. I got the phone on December and I never got one either. However I did experience the no signal popping up whenever I shut the phone off every once in a while. Never happened again after I upgraded to ek02. I'm just trying to get some info b4 I decide to go to Sprint and swap it out.. Now if those other two guys who don't experience radio crashes when clearing ram would let me know if they ever had LOS prior to ek02 I'd gladly appreciate it. Its just the whole thing has me skeptical..

I have both phones, and both perform the same way. As have the hundreds that I've troubleshot in the last three years at my store.
Sounds like you have heard your answer countless times, your just looking for feedback that follows what you want, not the actual facts.
Its not a crash. It will show a crossed out circle, flash connecting to voice(the 1x icon), and reconnect to 3G. If it isn't reconnecting, you have an issue. But, it will always reset.

1st I'll start off by saying two people already said they don't have this issue in this thread. 2nd how those the 1x icon show before reconnecting to 3g when Sprint disables the 1x from all their 4g phones from showing. And lastly I am glad you experienced the same behavior on all the phones you've worked on. I however didn't have that same experience. Anyways I already spoke to my friend (who works at a Sprint store) and he assured me his doesn't do it and if I would like I can come in to the store so he can order me a new one. Which I will do...
Edit: PS how dare you say all phones do it when I have my first epic 4g in my face and it is not doing this? Smh

[Q] Very weak signal on Note II. Radio Help?

Hey XDA Fam bam!
I have the T-mobile branded Note II and i'm experiencing the following problem:
Very weak signal.
Here's a little background. I rooted the phone and installed pmtr3 first V1 Rom and everything was perfect.
Then played around with other roms too and then the signal went every weak.
Then when I went back to pmtr3's first rom my signal did not improve. I would lose connection
everywhere. I replaced my tmo sim card, but I still experience this problem. I also went back to my stock nandroid backup, but it still did not help my signal problem.
Is there some sort of radio or modem I can flash? Am I the only one experiencing this problem?
I'm thinking it can be a hardware problem, but Idk. What input do you have my XDA fam bam?

Most problems FROM xda members devices are caused by user error. E.G. wrong roms. Not reading before doing stuff and trying to do too much. Its all over the forums. Maybe you havent read the same forum im talking about. Im talking about xda developers.
P.s. please no more pm's you are killing me. I try to read them but I just cant make it through some of them. I have to delete them.

Well I waited in line for an hour at my tmo store and got a new sim card as they claimed that would solve the data issue. But I also made them process an exchange. So I should have my new one tuesday. No more rooting until the problems solved.

Is this a recent development? Call T-Mobile to see if they're working on towers there.

If IMEI is intact, it's a T-Mobile issue. I was replying to say that I've had this issue before, once. I was going to call them to complain, but it was fixed in under 24 hours.

Happens to me here and there. sometimes I lose internet conection for 30min to and 1hour. I already called tmobile and told them bout it and how it started happening after they activated lte -.- they said its weird that it shouldn't be happening what should actually be happening is the data speeds geting faster. All they did is reset my data conection and gave me $5 credit for 6months:banghead:

Iv tried flashing stock via odin and it didn't help :/ so I called and got a replacement so far it hasn't happen anymore the thing that sucks is that the replacement I received is defective the home button is not sticking out how its supose to so I called and place another order but they are out of stock I kinda got upset when I was told I would have to wait like bout a week or so to receive my replacement so I asked if later on the road the home button started giveing me problems was I allowed to exchange for a replacement I wss told yes so I cancelled it cuz I could live with my phone like that not really a big thing

Sometimes if you press the issue they will replace it with a comparable model. They certainly have the T999L in stock if you want to ask if that's a possibility. Dont expect it to work, but could be worth a shot...

I called T-Mobile but they just reset the lines well that's what they said.
And nothing still the same data drops, iam going to try odin flash and I would see if that helps
Sent from my SGH-T999 using xda premium
If the flash doesn't help, wait another day or two and call back if it doesnt improve. Tell them you'd like to have a help ticket escalated because their last attempts did not help. Just try to get them to put you in contact with a tech who has the ability to deal with things on a more specific level. Most likely you only got the first level of support. They don't have many permissions to deal with a lot of issues. A lot if them are told that account resets will fix everything it seems like!
Hopefully though, things will jusy improve as they work on towers and upgrades.

Is this a network issue or a phone issue?

So obviously I am not on T-mo, but a buddy of mine is. What we are trying to find out is if when you are using ur data and voice simultaneously, and you loose data in the middle of a call, why do you have to hang up to get data back? I noticed this same thing with I phone users on GSM networks too. As you can tell I'm on Sprint and had no answers for him. All I could say is that I don't have to hang up to get my data back. Thanks for the help in advance it really is frustrating the mess out of him.

Try different modems. Aside from that the best first step I know of is call support and troubleshoot with them. If it doesn't help, let us know what was done and maybe we can figure something out.
If data works fine while not on a call, it's most likely either a problem with the phone, or on their end.

@ the moment can't try different modems because he is not rooted ( I'm trying to convince him though). I know I didn't make this part clear...we drive for a living so he may be going through an area that doesn't have 4g or whatever looses it and then instead of it just coming back while he's on a call he has to hang up. I will let him know to call support definitely if this is not normal.
Sent from my SPH-L710 using xda app-developers app
No idea if that's normal, but if it's happening while on the move I could see that making more sense. If on a call and you drive out of 4g coverage, it may or may not pick it back up when you reenter covered areas while still on the phone. You'd have to wait till it hands over to a 4g capable tower.
It's hard to say though, I think you'd get much more reliable info if you can get this answered by a tech who actually works on these things. When you call support you may have to have a ticket escalated to another level to do so though.
Anything I could come up with would just be theory and there'd be very little, if anything we could do from this side of the network to solve it.

Issues with wifi calling

Hi there
Recently I've been having a lot of issues with wifi calling. I haven't been able to receive any calls directly go somewhere voicemail and when I try to call somebody it says the call cannot be made at the moment
This really sucks because I got really bad cell phone reception in my house I was really thinking of using this as my main way of getting calls in my house
Is there any way to fix it or maybe troubleshoot it in anyway
By the way I'm running tweaked rom on my device

Has it always been like this (both in general and on the rom)? If not, any recent changes/tweaks/flashes/updates/installs that coincide with when you notice the decreased wifi calling ability?
Hmmm I think back now the issues started right after I rooted the device

Meaning they started on stock after all you did was root it? Interesting... I use it pretty often and haven't noticed any big difference between pre- and post- rooted. Maybe flash back to stock, test it out, and if all is well try again? That's what I would do anyway.
Most likely you are having these issues only when the phone has weak/poor wifi signal, can you confirm ?
