Can anyone explain the erratic signal?

My phone acts very weird and I don't know if it's normal or not. My phone's signal jumps between full bars and then 1 or no bars when I surf the web or send a picture message. It's downright annoying. Sure, it usually sends and receives data, but the fluctuating signal is getting to be beyond annoying. Anyone else having this problem? I'm on the current version of the Frozen Syndicate ROM.

Welcome to Sprint.
We all would like a valid reason besides spring saying "were currently fixing our antenna's."

What he said. This is very common on the Epic. Happens to me a lot =\
Running SRF 1.1.0 as well.

Someone please correct me if I am wrong, but I thought it had to do with the modem builds with the epic. I don't think it is a Sprint universal issue, because I did not have this issue on any of my previous sprint devices (that I remember).

Correct, it's the modem. That's why you see people on the forum complaining about the EC05 modem sometimes because it has signal bar issues, or stuff like that.

My phone does the same thing, even if it's sitting and NOT moving. Even my data speeds fluctuate sooooo much, it sucks. Sometimes Youtube will work great, other times they won't even start to load.

Hmmm...
It probably is the tower. Could be the modem to blame as well. Here in my house, I connect to my Airrave. 98% of the time, I have full bars with a stable connection with relatively consistent fast 3G speeds. The 2%, I get some wonky lag and usually then go and reset the Airrave. Everything works fine after I reset it.
I was just out of town in Vegas over the weekend and I had MAJOR problems sending MMS's, highly erratic data speeds, fluctuating signal, and overall connection problems. That was even when I wasn't holding the phone. Voice data and sending SMS's were very reliable, but forget sending MMS's or having good 4G speeds. I'm starting to think 4G is a drain both battery and money wise. Using 4G is like driving a classic car: It doesn't always start up, they're hard to find, they're finicky; but when it works properly, it's badass!
Random question: Is there an app that has a status bar for sending SMS and MMS's like the iPhone? For example, on the iPhone when you send an SMS or MMS, there's a status bar that shows the status of that message. If it's going out or lagging, etc. Is there an app that does that? I think that's a cool feature. Handcent just has a circular pinwheel, but stops when it goes out.

I would think it has to do with the modem as well. I have an EB13 based ROM, but an EC05 modem. I've noticed similar things, just not very frequently. It's strange...I'll have "great" signal, then for no reason, it'll dorp to 1x coverage and that SUCKS.
I'm thinking of going back to the EB13 modem as most people seem to think it's quite a bit better than the EC05 modem. I do think even that varies from phone to phone though, so I think it's mostly trial and error until you find what works best for you.

I have a fantastic update. Well it is for me, and might be for all f you also. Last night I decided to odin the EC05 modem again. And guess what? My signals beeen great!! Its always constant! No 4bars then zero in same spot no more!!
I already had the EC05 modem before I decided to do this. I recommmend odin'in you modem again!!
BIG NOTE*** I used the phone location for the modem.tar NOT pda.

I am having issues as well, i haven't been able to send any MMS for the past 24 hours. Regular texts go through just fine.

I'm having big problems with this recently in a location where I usually get very strong signal with 4G. Can anyone point me to step by step instructions of how to safely and correctly flash just the modem file?

Flash in Odin.

4G losing connection and not reconnecting

Is anyone else having this? I still have 3g connected, but if I look at the phone periodically, the 4g has an X on it (red x, im on honeyglow) it will reconnect if I toggle it, but if it drops it will not reconnect, like from 3g or wifi.
Is this s known issue and is there a fix?
Oh, and Im on the LosTKernal OC to 1.6 (stable) and Starburst 1.6, it did it on 1.7 as well.
Thanks

Which kernels have you previously tried? I tried one that made my 4g stop connecting even after switching back to stock but I did find a fix so give me some details on what you've tried so far....
Sent from my SPH-D710 using xda premium

I think I have only used ZedoMax, and then this LosT Kernel, or versions of it.
I had midnight ROM, now have been running Starburst. I think another configuration I had dropped signal on data a lot and had trouble switching between WIFI 3g and 4g. But this has helped my LOS issues as best I can tell.
If I can get 4g to work (im in Dallas, lots of 4g) great, if not Ill just try to ignore it.
If you have a fix, that would be great.
Thanks!

Honestly, if I had a choice between this and the screen wake lag, I'd not worry about 4g.
The screen wake lag is rediculous, it takes 3 full seconds to wake up with my class 10 8g card in it.

Well, what I did was Odined Crawrj's odexed with root and Busybox. You would want the deodexed version obviously. Run that in PDA slot. It will keep your data but then you will have to Odin back akernel with CWM like LoSt. It fixed all of the 4g and Wifi not connecting crap I had going on from something I triedthat had borked changes

[Q] EI22

I am somewhat new to the epic scene, and had a few general questions that i have searched for over the forums here but get such a broad variety of answer im unsure of what is true and what is not.
Basically, my phone is set up with the following :
Firmware Version : 2.3.5
Baseband : S700.0.5S.EG22
Kernel : 2.6.35.7-g67f7514
Build : CleanGB.b13.EI22
I haven't updated to the latest CleanGB (which i plan on doing when i get home today)
But the problem is as follows:
My data connections suck..... I have replaced the phone 3 times (in less than a month) I have updated the PLS, changed the wimax settings with the MSL code, and had sprint flash it as well. But my connection speeds are so messed up.... I get 4-12 mb's Down, but only like .2-.8 up.... Can anyone recommend a GB build (if the updated one of CGB is better that's fine too) and kernel/modem to use in combo with each other that may help with this problem? It doesnt seem to matter what build i use, they all seem to have this issue.
Thanks alot!

Try updating your modem. You need to Odin the EC05 modem then flash the EC05toEI22.zip. If you think it is software related as opposed to Sprint network problems (i'd bet on that) then Odin in stock EC05 and test it there.

Thank you. I will try that when i get home as well.
Is the wimax and wireless running on the same thing? The reason i ask is becuase when i connect to a wireless network it will do 10+mb down and usually 5+ up.....

They all go through the modem. But 4G is dependent on Clearwire's network nearest you and wifi is dependent on your router switching speed and network speed.

Gotcha thanks!

So after having to flash my phone about 15 times.... i thought i had broken something, i flashed a stock rom, them CWM..... then black screen and wouldnt power up. So after messing with the phone itsself for abit i finally got it to cycle again. But now im Running ASC/Samurai with the ec05 to ei22 modem. Runs so much better, and my wimax upload has almost doubled.
Thanks again for the help.

Signal Strength

I'm curious as if anyone else is having this issue, or if there is a simple fix I'm missing. I'm currently on Calk's ICS ROM (FB27) and my signal strength randomly vanishes and appears as if I have no signal. I believe it's only appearance though, as my data still loads fine. It's not a big deal, but it is rather annoying. Is there a way to fix this? Also, I apologize if this has been discussed elsewhere and I missed it. Not trying to be annoying, simple curious. Thanks!

Are you referring to your wifi radio or cellular radio? I see what you describe with the wifi radio on all of the ROMs I've been using. I'm currently on MIJJz BLEND which is based on Calk's FB27 and alot of the time my Wifi signal strength shows 1 bar but when I go to the Wifi settings where it is scanning for networks the same network shows up as 3 or more bars. If I drop and then add the network the notification area shows three bars but eventually drops back to one bar.
But I recall this happening on the stock ROM too.
Haven't seen the issue with the cell radio.

Notice my actual phone signal. It does that randomly. The Wifi signal is always fine, I haven't had an issue with that. I suppose it's just a bug that will be worked out eventually. Like I said, it still works fine, it appears to be merely visual.

I am having this problem as well. I have tried several different modems and several 4.0.3 roms and have had this problem with all of them. I have noticed that my signal strength stay consistently between -100 and -106 dbm even when using my airave.

Have same issues ever since flashing fb modem and fc. Never happened on el 29 modem. Just a bug I guess

Same Problem
I've had the same problem on the same ROM.
I feel a bit sheepish as it didn't occur to me that the problem was only visual...

I have experienced the same thing. My bars come and go constantly... Even if my phone does not move....

I doubt its a bug. I had all types of Sprint phones and they all did that. It does it a lot on 3g. Its like 3g steals from the bars..

It is a known issue with most of the leaked builds that have come out recently. The bars for Wifi, 4G and 3G were all effected by it. It was purely visual. Qbking77 mentioned it in just about every review he did for the different leaks (and it's been thoroughly covered on several development threads).
If you'd like to confirm your actual signal strength, I'd recommend using a third party app to see what your actual signal is.
Supposedly it was fixed in FC15 or FC18 but I don't remember which it was.
Hope this helps!

Are you guys saying this problem doesn't exist on Calk's 2.9.2 ROM? I'm using 2.9.0 (just never updated) and I get this all the time. I think the signal actually does suck though. I see the -DBM changing too. Is the reported dbm visual too? I'm confused. My phone keeps switching to 1xrtt a lot when this happens too. I just figured it was cprint being crappy around here. When I force roam on verizon the signal bars don't bounce up and down like this.

As far as I know it only effects the visualization of signal strength, not the actual signal strength itself. That being said if you're running one of the leaked ROM's chances are that you're probably running a leaked modem too. People are having all kinds of results with the new modems. Try flashing just your modem and see I'd you get a better signal.
EDIT: After flashing the new modern be sure to update profile and PRL.

Dropping internet connection

So I've noticed on every stock GB ROM and every custom ROM ive tried (including some early ics roms) that whenever my phone decides to switch from 4g to 3g or if I switch the wifi off, basically every time the radio switches, the internet stops loading whatever it was loading. does anyone else have this issue? It gets pretty annoying sometimes although coverage has been pretty good lately.
I could try and list all the roms ive used but it doesnt matter, the problem is consistent.

from what i've read, it's just an inherent problem with this, and most, phones that are capable of using both networks, when forced to switch from one to the other, the "handoff" is never clean.

Ok, so I started a market download over wifi. Turned the wifi off at 10%. Now it starts trying to connect 3g first, which connects almost instantly and the download resumes. But when 4g connects a second later, it just goes to sleep and the download stays where its at until something else wakes up the 4g. Not a huge deal I guess just bothersome that it even happens.

I wrote a download manager before and made the download thread delay and re-attempt if the connection was by abolished. Maybe stock touchwiz browser doesn't do that
