Extreme los? - Samsung Epic 4G Touch

so I'm getting los A LOT now.. anyone know if there was something that changed?
I didnt get it too much with the LOS checker viperboy, but after flashing to the LOSD it goes crazy with LOS, and I'm getting maybe 5-10 reboots a day..
I uninstalled LOSD and still getting a bunch of LOS..
running
2.3.4
eg31
2.6.35.14 rouge et 1.1.3+
gingerbread.eg30

Upgrade your radio (modem)

Try running a stock kernel for while. A lot of folks have reported this helps with LOS.

Use either stock ek02 kernel with cwm and ek02 modem or use el13 kernel with cwm and el13 radio.

If you still suffer EXTREME los then maybe take your phone back and have it replaced.

I noticed this issue with LOSD as well. I'm currently on EK02 modem with an EL13 system and honestly when I did the reinstall I didn't bother to put in the LOSD addon and I've had ZERO LOS for 2 weeks now. And for where I'm currently at (Mi with some very bad areas with really poor signal) I would of figured I'd hit LOS but I've yet to even see it. I'd remove the LOSD script and try running without it and see how things go. So far it's worked for me very well.

is it supposed to take a long time to flash the modem? for EL13..

It took me a little while flashing the entire package (around 5 to 10 minutes).

I believe some early versions of LosD were giving false positives. You can use "No Signal Alert" from the Market. It will give you an audible beep if you get a LOS and when it reconnects

EG31

I just wanted to know hows LOS for you guys on EG31?

LoS is worse for me on EG31 than EG30. I can't get 4G to work ever since the first time I experienced LoS no matter what modem I use.
*Just read the thread about 4G not working in Boston, which is where I happened to be visiting this weekend. So LoS and my 4G issues seem to be unrelated.

Thanks, I'll test out 4G when I fly through Atlanta, and try that fix if I need to.
*Update:
It was Boston. When I got to Atlanta 4G worked fine.

Just to add you don't need to use su like those instructions state. You can get your msl code without root.

LoS on EG31 is the same as it was for me on EG30. ~Once a day.
minor improvements but nothing to brag about. 4G works fine.. 3G speed crappy as before anywhere from 50 to 150KB/s ...
Hmm, that sucks that its the same week thanks for the help

I am right that if you flash EG31 you cannot go back to EG30. I know there is EG12\30 but it is not the same as EG30 that came with the phone right?

The EG12/EG30 is the exact same thing that came with the phone.
All you have to do is flash it in Odin, I've went back and forth between them twice already.

You need to update profile after EG31 and then reboot
I haven't had a single LoS since going to EG31. Even using other kernels. Use to get LoS on EG30 with any other kernel other than stock.
P.S. watch me get a LoS now lol

LOS on EL13

I just experienced my first today
Anyone else?
Sent from my SPH-D710 using XDA App
I got it today as well.. after I flashed it, had los twice while underground..
Never once.
Are you using the EL13 baseband?
Also, What kernel?
Yup, using Calkulin's stock with chris4g's repack and EL13 modem. Maybe it was just a fluke, I was at my parents house which is in a decent service area, pulled out my phone to see the circle with the cross through it. Had to reboot to get service back. Eh, I'll just keep an eye on it.

I haven't had LOS since. I'm on EL26 now, and signal is stronger now.
Still LOSing here... I've tried EG30, 31, Ek02, EL13, and EL26. I get LOS on every one as soon as I go to work. The signal there is very week and the phone has to work hard to maintain a signal all day.

Sounds like it is a network dead spot and not related to the phone.
Sent from my SPH-D710 using Tapatalk
There is another topic we were discussing this issue. Basically the problem isn't fixed but they are attempting to tweak it so instances of LOS are getting smaller and smaller. Sounds like becuase of the location you are having a higher probability of tower disconnect or switching to roam which increases the likelyhood of you experiencing a LOS.
Yes, EL13 still suffers from LOS (aka it is not really fixed). Personally I haven't had one in EL26 (had a couple in EL13) but if you are experiencing it in EL26 then it isn't fixed there either.

Love Hate relationship. Return it?

I absolutely LOVE everything about this phone EXCEPT the LOS issues!!
I've only had it for 5 days now and experienced 3 LOS!
Since I'm still within 14 days, should I return it? thinking of getting the Photon instead.
From personal experience I'd say hang on to it and try flashing some of the newer releases to see if it doesn't improve the LOS issue.

I know you are asking because apparently you need the help of others to make up your mind... (sorry I am a smartass) But quick question what rom are you on cuz buddy LOS is a thing of the past up in herrrre... And that PHoton are you serious would you trade in your S clase Benz for a C Class Benz....
Root that sucka and flashing one of the stock EL29 roms or do the upgrage on your phone for the complete stock version... Oh yea and if you gonna ask where the roms are then maybe you should return your phone...LOL (smartass again)
exactly, flash something different (I'd recommend calks) and that issue goes away :O
Sent from my SPH-D710 using XDA App
Doesn't even need to flash roms, root, and all that. Just OTA to EL29 and it should get rid of the issue.
Hey playya like the benz analogy, I was thinkin the same thing about the photon swap.
Yea update your phone dawg LoS was fixed officially in december
If you have Los on EK02+ get a replacement

What's the latest stock version?
I'm on EL29 version 2.3.6 running fully stock since there was no reason to go custom until now.
and thanks for all the help so far. looks like I'll either update to latest stock version or go custom.

I think almost everyone on this forum experienced frequent LOS until Sprint issued a firmware update that fixed it. I haven't experienced LOS since and it would happen to me several times a day. Update your firmware and you should see this go away. (my recommendation is to go with Calk's non-ICS firmware since it's probably the most stable at the moment)

Sounds like you need to get your phone replaced. The loss of service was fixed with ek02. el29 was the update after ek02 and it's the most recent update. You shouldn't be having any problems.
And you're flat out insane if you step down to a photon.

I'd definitely suggest Call's E4GT rom its one of the better ones out there, i havent had any issues with LoS but i did just get my phone in december. But for sure keep this phone !
Sent from my SPH-D710 using XDA
Yea, I would try flashing Calk's EL29. It should solve the LOS issues while improving the phone in mutliple other areas as well.
If that doesn't work, just take ot back to Sprint and replace it with another one. I would highly recommend staying with this phone though, not the Photon.

I was initially going to flash to Calks ROM anyway but this phone was pretty awesome out of the box until the LOS issue.
I think it's safe to say Im keeping this phone since there seems to be a fix for LOS

Exactly my thought... OP, as you are on EL29 you should not be experiencing LOS. Are you sure what you are experiencing is actually LOS, and not just poor Sprint service?
I'm not an expert flasher but the devs here have made it so simple I've been able to play around with several of the ICS releases but I always return to sfhub's stock-rooted EL29 and get amazing performance out of it.

I believe so. It says something to the effect of no service and roaming charges will be applied. So i'm assuming thats LOS.

If your phone is up to date I wouldn't flash anything on it. Just take it to a store and get it replaced. The LOS issue has been fixed. Unless your counting the ghost LOS problem. I had that one until I switched to EL29.

Ummm try to take a screenshot, idk what you're talking about?
Only time I ever get LoS is when clearing RAM in Task Manager, which I think is normal? Only for 2 seconds then pops right back up and runs perfectly

GPS not locking until reboot - post custom rom

So I recently installed Calkulin's custom rom v2.9.2 and now my GPS doesn't lock unless I reboot the phone.
Any fix for this? thanks.
Try GPS status app

just tried this, doesn't work on my phone.
Only thing that works is a reboot which is a hassle everytime i need a GPS lock.
anyone else w/ any suggestions? I'd hate to go back to stock ROM.
Doesn't the GPS continue to work for a few days, before requiring a reboot?
Thats the case with my phone, try different versions of the rooted rom, or radios.

THanks. upon reading a bit of that thread, I found out that through using "GPS Status" I can refresh the "A-GPS" which I didn't know previously.
This seems to work so far.
I'm running the same rom and have no problems with any of my radios, I did also install the EL29 modem when I installed the rom. You may need to try different modems, they work differently on different phones even though you're running the same roms. Also, don't forget to update profile in /settings/about phone/updates

I was originally on EL29 Stock so I'm assuming when I flashed Calks 2.9.2 the modem's the same.
Is there a link where all the modem's can be found? and can I flash any modem?

Flashed the FB21 Modem and this one looks like a winner!
I'm getting instant GPS locks w/o resetting, rebooting, opening an app etc etc.
On top of that, my 3G/4G speeds have increased!

I tried the fc05 got 13 then 4G started to sleep in the middle of things. The trick is to find "the one" that's stable and everything works. I'm gonna try the others and see how they work. But I know that this one works for my phone.

Update if anyone's interested: FB21 modem w/ EL29 Kernel was good but still had GPS locking issues. I was getting roughly 85% locks (which isn't bad since I test often). FAST download speeds though.
So this got me thinking: When my phone was stock, GPS worked brilliantly. It wasn't until I installed a custom rom that it started to have problems. The difference was the kernel and modems.
So now I flashed back to EK02 modem and kernel (still running Calks 2.9.2) and my GPS has been locking 100% of the time. PLUS my phone is silky smoooooth!
Crossing my fingers that this will last....

which is the best ota?

i just did a factory reset back to eg30. which is the best ota? i like this one seems really smooth.
im actually on the eko2 update right now and wondering if i should stay on it. was on el29 for the longest time and i like this one. what are your thoughts?
