I'm having trouble with my EVO staying in 3G coverage. My phone is fully rooted and running Froyo (The problems were the same with the Eclair build however), have the 2.05+ radio installed (however the problems were the same with the 1.39 radio as well) and I'm living in Michigan.
At any given time my phone will slip into 1X coverage and will seem to lock in there. When I first received the phone I felt like the phone quality was subpar compared to the Hero I had prior. I'm not sure if its been a firmware issue or network issue or simply a phone issue (starting to think the later), but hoping its a simple fix with something else.
About a week ago I was on a trip across Michigan which should have had 3g coverage the entire way (I was a passenger and trying to use wireless tethering to do some work along the trip). I would constantly go into 1X and would have to restart my phone to get back in 3G. Even at home I'll go into 1X and will have to reboot my phone to get it back to 3G.
I've tried Real Signal as well during these times and it also shows no 3G signal.
Anyways, anyone else experience this? Is it likely a bad radio or something else. I hate to have to return the phone and go through that process plus root again but I might have to at this point.
Thanks for any help that can be provided!!
Hmmm, whereabouts in MI? I am all over the south east and have never seen my phone drop out of 3G yet.
Have you tried wiping everything and trying stock rom w/OTA 1.47 just to make sure it isn't the ROM?
I am having the exact same problem. Using 2.0xxx radio and Fresh 0.5.3. I recently exchanged my phone and got a new one. The first phone did not do this
Try this:
When it shows you no 3G coverage, instead of restarting, go to-- SETTINGS> WIRELESS & NETWORKS> scroll down and look at "Mobile Network". When i get the 3g problem it says "Connection Failed". I think uncheck that box and re-check it and it connects back to 3g again (for a time, but then I have to do it again).
My MOBILE NETWORK settings are: Data Roaming = OFF, Always-on mobile data = ON, and CDM Roaming mode is set to: SPRINT only. Call guard = ON but i dunno what that means.
I dunno wtf is going on with this. Im in Houston and this issue is really pissing me off because i actually got a Novatek screen this time and don't want to risk taking the phone back and getting the Epson...
Anyone else experiencing this retarded issue?
Elegant: I'm in SE Michigan as well. I've tried several roms and have had issues with them all. I'm currently using a Froyo rom with similar issues as I've had with stock and other eclair roms.
As for checking/unchecking the box as you stated in Froyo I don't have that option available... I'm sure there's another way to get to it but I can't through settings. I think there was a #* code to get to where you are talking about but I'd have to look again.
It is a very annoying issue and like yourself I don't want to have to return my phone if there's a simple fix.
On a side note: How do I find out what panel I have? I've been considering the kernel that would get rid of the 30 fps cap but haven't yet pulled the trigger in part because I don't know which panel I have - and because I need to learn a little more about it before I go ahead with it.
http://forum.xda-developers.com/showthread.php?t=719763
Post 3 tells how to determine screen
Thanks for your help - got the kernel and now get around 40 FPS. Now if I can just figure out why the phone goes in and out of 3g on occasion. Its really not as big a deal when I'm at home but when I travel it is a pain.
well i returned my phone and got one with an Epson screen. im using Fresh 1.0.1 and it is even worse. i cant even use 3g data for more than 5 seconds before it disconnects. i've read some stuff about APN but dont know how to refresh/update them. i've updated PRL and Profile and nothing helps. how am i having this problem with 2 phones running 2 different ROMs? last rom was fresh 0.5.3 and now it is fresh 1.0.1...
anyone help with this APN issue? (i dont even know what APN stands for)
i actually am using the kernel for 55 FPS for Epson screens. would that be a factor either?
I'm and having the same issue with 3g.
Every thing worked fine with the first stock root of 1.32.651.1, PRI 1.40_003, PRL 60666.
With the second root of 1.47.651.1, PRI 1.34.651.1 now my 3g is unstable.
I don't know what FPS has to do with any of this, but I put radio radio-1.39.00.04.26 and it seems to improve a tiny bit, but I don't know how to update back to PRI 1.40_003.
Not happy
Also having problems in SE Michigan. Just started today after installation of Fresh 1.0.1 and the new radios. I also have a co-worker with and unrooted EVO and the latest OTA/Radio with the same problem.
I have a rooted EVO (DC 3.2.3). My wife has a stock EVO (fully updated).
Last night our phones started bouncing between roaming/sprint 3G, while we were sitting at home.
We started getting this error if we turned off Data Roam:
"Data Call Failure
Error Code 67: Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again."
The error pops every time it tries to connect to Sprint's mobile network and fails.
We also live in Michigan. Perhaps they are doing provisioning?
Rebooting + update Profile/PRL seems to help, sometimes, but not permanently.
I am having the same issue with my 3g coverage.
When I go into my settings and turn mobile network on, it connects but then immediately says connection failed.
Does anyone have any suggestions as this is getting really annoying and frustrating.
Went to a Sprint store last night; apparently Michigan was having some significant network issues (the store reps said their phones kept getting disconnected as well), and that it was expected to be resolved by sometime today. After a reboot last night, I haven't had any more issues myself.
Anyone have an issue with their phone randomly dropping Wifi/Cell connections? Sometimes it doesn't happen for a day or two sometimes it happens 3 times in 5 minutes.
Starting to think my phone is defective...

I've tried that and it's still dropping... Would PRL/Profile also effect my Wifi connection? All data connections drop.

I'm having the same issue with Wifi. It'll still show as being "connected", but there won't be any data coming through. I'll have to toggle Wifi on/off to get it back. Sometimes it'll work for a couple of hours before having the data issue again, sometimes less than a minute.
I'm on stock, rooted.

Connections optimizer is off for me too - My phone shows a clear signal disconnect and reconnect (The wifi bars/3g symbol disappears completely) during this time all data connections fails - including texts. This is happening when I'm staying in one area so it couldn't be a tower reconnection issue.
I'm going to try taking my phone into a sprint store today to see what they say.

Ah, it sounds like our issues may be different then. My issue is solely with Wi-Fi (haven't noticed issues with 3G). When it happens for me the Wi-Fi icon in the status bar doesn't change, I just can't connect to anything.

Yup, same here. Seems like the 3G radio does the same thing, but not necessarily at the same time as the WIFI. At first I thought is was only the WIFI too, but 3G is affected, though not to as severe a degree. My WIFI was actually disconnecting and failing to reconnect. Turning off connection manager made no difference. I did however notice that the WIFI at my work (WEP encryption) never seemed to do this (at least I didn't notice), so I changed my home network WPA to WEP and sure enough, it stays connected. Was still failing to load occasionally, so I went even further and changed the router to a single channel rather than "Auto" and set it to "N Only" (due to having a similar problem with a laptop I used to have, with a similar solution). Problem fixed. I'm using an Amped R10000 just FYI, not sure if it matters. Very annoying, and given the number of occurances being sufficient to start a thread, I'm assuming this is a common issue and will hopefully be fixed by a firmware update. In the meantime, we should probably all start calling Sprint daily and complaining. Maybe they're not even aware of it. Probably not enough of these phones in circulation yet for them to worry about it.
Mine will do this from time to time. Stock not rooted. I will have full 3g bars and full wifi bars and my data will just hang. If I turn off wifi everything works again. Some times when I load a game that has to connect to Facebook to play against friends I have to close the app/game, remove it from memory and reload it to get the data to work. Same thing for Pandora. It will load a song to 2% and hang until I stop wifi or reboot the phone. It's not an everyday thing but some days are worse then others.

"Good to see" from the perspective I thought it was just me. Things described by others happening to me as well. Personally, I find I like the wifi/3g auto connectivity feature - when it works. Got my SGNII on Thurs last week, and connected to wifi at work on Friday no issues. This morning, the Note picked up my work wifi without a hitch.
At home, over the weekend, I was getting spotty connection, sometimes no connection to my wifi. (Disclaimer - I have my main wifi @ N/5ghz. An access point was added with wireless G via an old Netgear router-turned-AP.) After several attempts of moving the AP from one cat6 jack to another, I finally moved it to my main level. Oddly enough, so far, so good. Certainly possible the router's radio is pooping out.
What I notice happen with connection issues though seem related to the Note seeing my wireless G, trying to connect, but unable to do so until/unless I reboot my phone. After moving to the new location/jack, everything seems to work OK now (knock on wood).
Having said that... I also think the 3g radio (HW or SW?) is a bit wonky, as my old HTC Hero seemed to have more bars at home, IIRC. Whatever it is, just seems a bit lacking, IMHO.
Sprint is updating to LTE in many markets ive noticed my 3G drops says preparing networks and reestablishes the connection to 3G. I live in Fort Wayne and issue the permits for the tower co-locates and they are close to going live with LTE here so I know thats my problem. I can live with the flakiness for a few more days. I have not had issues with WIFI drops at home.
Sent from my SPH-L900 using xda app-developers app
The same thing has been happening to me here on Long Island. 3g drops and reconnects. Sometimes it doesn't and a reboot fixes it. I also notice after the disconnect and reconnect it states my PRL is unknown. I have done a PRL update many times, a Profile Update, a RTN reset, and a factory reset. This happens on the stock rom and any custom ROM. It's driving me insane!
hmm maybe mobile settings?
Ive found LTE/CDMA setting to be not so good.
Its providing me eHRPD signal which is stop and go web browsing is murder.
CDMA only setting is providing Rev A signal fast web browsing
Sigh, so it seems as if you guys are losing wifi/3g....is it affecting voice radios or LOS/dropped calls?

I haven't been on the phone when it's happened so I couldn't tell you - Nothing like the LOS on the E4GT. When the data connection does cut out it immediately reconnects. Doesn't really impair the functionality of the phone but it happens enough to be annoying. With a 300$ price tag I expect my device to be without defect.

I'm not having LOS /dropped calls just data creep with LTE/Cdma setting enabled.
Speed test show same data speed numbers as CDMA only setting but when browsing data arrows tend to pause more making for slower page upload with LTE/CDMA setting enabled.
According to Sprint store tech such performance is common with that setting.

I am on CDMA only. I should have mentioned that in my first post. This does affect phone calls too as ill be on the phone and the call will drop and the "out of service area" message comes up. It doesnt matter if I'm on my Airave or not. I tried different prls which doesn't seem to make a difference. I am starting to think there is something wrong with the phone as my girlfriends S3 doesn't do this. Maybe Samsung will release some sort of update to fix this issue.

I made the change back to CDMA only mode this morning and it has solved my WiFi issues as well. I was also struggling getting a GPS lock with LTE enabled. GPS toolkit would show 20/21 satellites found but it would never get a lock. After the reboot back into CDMA mode it locked in 5 seconds.

This is the Task650 and Ktoonsez AOKP. VERSION: d2att(4.1.2 JZ054K) from December 2nd release.
My data network goes in and out at random. It actually started happening about 4 days ago on an older build by Task650 & Ktoonsez but I saw the new one so wiped dalvik and Partition cache and rom'ed. Even after flashing the new ROM, data is acting the same way. It is completely random, happens when the phone is in use or when it is locked. I can tell when data connects for short spurts because I hear the notices for new emails. All in all today, I've maybe had 5 minutes of HSPA/3G data and the rest all I have is cellular network for calls. reception strong, and I am in areas where I always have good connection and speed.
Any ideas? Kind of frustrating if I am out to lunch and want to catch up on things (stuff is blocked at work). Also I am paying for data I can't use :/
fully wipe and reflash.. try a different modem

I am admittedly new to flashing, I just assumed everything was in the package. I flash the ROM and Gapps, is there a source for different modems?
This is definite disconnect of data DHTP. Can't get anywhere, and there is no symbol where there usually is on the reception bar. When it comes back for brief moments, it has either HSPA, 3g, etc.... on the bar.
are you able to send and receive calls? text?
I flashed that rom three days ago, and i had to replace it via warranty. it showed it had signal, but couldnt make any calls or text at all. then i Odin back to stock never worked again.
Don't think it has to do with any rom. Noticed that my wife's sgs3 has had a problem sending and receiving texts and the network drops a lot as well. She is completely stock with the jelly Bean update. My network has been a little suspect over the last few days also. Might just be the service.

Hey Guys, I may have found the culprit...sort of.
The wife has an iP5 and she said to me while we are driving to a holiday party 'I finally have official 4G LTE on my phone'. To which I of course ask what she means. Apparently the same day I started not being able to connect to data networks, is actually the day that ATT fired up their 4G LTE tower(s) in the Lehigh Valley area. When I do get data on occasion, it's when I bump down to 3G and HSPA. Unfortunately, the ROM has a bug where I cannot force it to look for just 3G, I go to save the setting and it immediately jumps back to LTE.
I may just have to flash to a version that definitely supports 4G LTE data. This issue occurred before I flashed to newest ROM, so it has something to do with the core build or modem that both versions use.
Ngriffin, if you find any successful modems please let me know. I like the ROM but I can't go without a data connection much longer.
So, for those who care, I flashed Gapps and also Flashed a new modem (http://forum.xda-developers.com/showthread.php?t=1831898) version UCLG1 and it's a no go. A few in my area said it worked great for them so now I am a bit discouraged. Northeast Pennsilvania Area.

More info, tested using the Wife's Ip5 and realized we don;t have LTE at our house, so I'll have to wait until we get withing range of the LTE tower(s) to see if it has an issue. However, I now have data reliably.

That's normal. LTE is data only and isn't used for phone calls.
I've been running Task's AOKP on my SGS II and III for a while with no data issues. Check your APN settings. If you're in an LTE area, you should be able to sit on the ATT LTE APN and have no problems, even away from LTE coverage.

To update further, LK3 modem worked for a short while, but once I left the area of my immediate cell tower and it had to connect to another tower, it couldn't. I flashed ALL modems in my list a post above and NONE work. I'm kind of pissed right now.
Any ideas? I'll probably to a full backup and then flash a completely different ROM and cross my fingers. Is there an official JB stock ROM sans the bloatware that is stable and can connect to LTE (or any data network reliably for that matter)?
It was my APN *facepalm* Thanks for the suggestion. It was sitting on wap.cingular instead of the LTE and it was causing the issue. I'm on modem CLH1 and it is working, I have the 4G (3G) symbol now and data is connecting. Well, I learned something thanks! :victory:

I started having issues with mine about the same time. I haven't been able to figure it out yet. I had just gone to JB and flashed a new ROM. Then started noticing not just data being very spotty but also my calls (both incoming and outgoing) were very spotty too. Both seemed to only work about 50% of the time. I have since completely wiped and factory reset twice. I even Odin'ed back to a stock Rout66 jelly bean system but I still have issues
I have updated my APN to ATT PTA but that hasn't helped. What APN settings did you go with? Is ther some specific for LTE coverage? On the stock system now I can actually see the LTE icon when it actually chooses to connect.
Also, where did you find other modems. I was told in another forum not to flash any that weren't specific to Jelly Bean and all I have found is the stock I747UCDLK3 which is already on my phone. I did try flashing that seperately just to see if that would help but did not.
I need to get my phone working pronto as it is my main phone for both business and personal phone calls. Any help would be greatly appreciated. Thanks in advance.

When you're on stock, only thing you can do is check with your carrier and they'll either tell you that it's something on their end being worked on or that your SIM card is faulty.
This happens to me on tasks AOKP ROM at least once per day, but it usually only happens when I turn on LTE. Basically what happens is the phone has cellular service but no data, after a few minutes it comes back. What I have noticed is that its to do with LTE so maybe there's a problem with that?

Task's AOKP doesn't set the default APN to LTE for Rogers so you might wanna make sure it's your default APN.
I finally got LTE locked on with Telus other users confirmed Rogers, AT&T and Bell(thanks) . No service disconnections, even while on wifi.
The problem I see is conflicting settings while flashing roms/modems. This seems to be the only fix. I'm pretty stoked I figured this out because I was about to switch back to my s2x out of frustration.
This took a lot of trial and error, literally had nothing to go on and no where in particular to start. Enjoy.
MAKE SURE YOU ENABLE LTE TOGGLE IN ROM AND HAVE IT ON BEFORE STARTING.
1. Network mode(settings/wireless & networks, more/ mobile networks/ network mode) set to gsm/lte/wcdma
2.Phone setting in test mode *#*#4636#*#* set to lte/gsm
at&t / rogers should select gsm/lte/cdma in test mode
3.Recovery flash latest modem mumLL1
(at&t users flash ucdlk3)
Wipe cache/dalvik
4 . Reset. Give it a couple mins to ask the network for lte.
If you disable Lte(through toggle) and want to use 3g/H+ for battery saving, the only way I've been able to reconnect to it; is to re enable(toggle) and reset, wait a couple mins to connect.
Side note: depending on your 4g service area, it may bounce around 3g/H+ which is normal.
When you place a call it will drop to 3g (the believed reason for this is that the phone knows you won't need heavy data so falls back to ease up on the battery during calls) but will reconnect a couple mins later. Our phones are slow to negotiate Lte connections with the radio testing sockets and network stability before committing, so be patient.
Let me know if this works for you and which network. Thanks.
Modems can be found here

Which rom are you on? Should be up in your toggles. Basically it changes you network settings from cdma/gsm to lte/gsm/cdma. But it conflicts sometimes.

Worked for me on Bell Mobility.
Edit: Running CM10.1 (latest nightly)
No Test Mode using CM10.1 ROM

I finally got LTE locked on with Telus other users confirmed Rogers, AT&T and Bell(thanks) . No service disconnections, even while on wifi.
The problem I see is conflicting settings while flashing roms/modems. This seems to be the only fix. I'm pretty stoked I figured this out because I was about to switch back to my s2x out of frustration.
This took a lot of trial and error, literally had nothing to go on and no where in particular to start. Enjoy.
MAKE SURE YOU ENABLE LTE TOGGLE IN ROM AND HAVE IT ON BEFORE STARTING.
1. Network mode(settings/wireless & networks, more/ mobile networks/ network mode) set to gsm/lte/wcdma
2.Phone setting in test mode *#*#4636#*#* set to lte/gsm
at&t / rogers should select gsm/lte/cdma in test mode
3.Recovery flash latest modem mumLL1
(at&t users flash ucdlk3)
Wipe cache/dalvik
4 . Reset. Give it a couple mins to ask the network for lte.
If you disable Lte(through toggle) and want to use 3g/H+ for battery saving, the only way I've been able to reconnect to it; is to re enable(toggle) and reset, wait a couple mins to connect.
Side note: depending on your 4g service area, it may bounce around 3g/H+ which is normal.
When you place a call it will drop to 3g (the believed reason for this is that the phone knows you won't need heavy data so falls back to ease up on the battery during calls) but will reconnect a couple mins later. Our phones are slow to negotiate Lte connections with the radio testing sockets and network stability before committing, so be patient.
Let me know if this works for you and which network. Thanks.

Ok sounds promising but unable to get my ATT phone running ROM cyanogenmod10.1 03/04 nightly into Test Mode using the keypad code provided. This does work for stock ROM phones. Do you know any other way to get into the test mode?
Haven't tried stock. Im on cm10..

I'm on CM10.1 not stock.

Yeah I'm pretty sure everyone is using cm10 or aokp. Not sure if stock is having these problems. If they were I'd be on the phone yelling at Telus.

So let me get this right. This fixes the signal jumping around on cm10/aokp ROMs?? That's the only reason I stay on a stock based rom. I'm tired of seeing my signal jump back and fourth from 4g to 3g etc. On stock I always have a rock solid signal. It does not jump around..... Thanks in advance...

Yes for me and others didn't even get 4g, also it would completely go out of service. Now I get steady 4g.

Any alternative way to get into "test mode" other than using the keypad?

Sorry man, I tried looking around for a way. Could be the rom you're on. I know Liquid and Carbon are fine. Probably a couple more that I don't even know of, others have success with.

stock lies to and shows 4G all the time, cm10 and show the truth. the s3 sets at 3g until data is needed then transfers to 4g
Just checking to see if I am the only one having these issues.
I have the 3 XL on ATT, and I randomly have no internet access over mobile data, even though the notification shows LTE and decent signal strength. Screenshots attached to show what I'm talking about. This has happened about 4 or 5 times since I received the phone a few weeks ago. I went to ATT and got a brand new sim, thinking that my old sim may have been going bad, but that did nothing. Only way to get the mobile network connection working again is to reboot the phone.
I have also noticed a few times that the squeeze for google assistant feature will stop working, and I have to reboot the phone to get it working again. Anyone suggestions? I am leaning towards just doing a factory reset this weekend, but I would like to avoid that if possible.
Thanks
dont know about the edge squeeze assisit not working (i use edge sense module and app) but i have to reboot or go into airplane mode to get data to work when i get the x. maybe using a different apn would help... im on att too
AT&T issues
This is now a problem for me. I have to put my phone in airplane and then back to lte at least once a day in order to get mobile data working again. I'm not really sure if it's a network issue or a phone issue.
Issue for me here too, but I'm in Australia on Telstra network.
