i dled the 11.19 evo radio and my text messaging started getting 10 min delays, then 20 min delays and sometimes none. i flashed back to the official 7.28 radio to see if that solved the problem, and no it didnt. any ideas from anyone?

Did you *228 (program) your phone after you flashed your radios? Have you contacted Verizon to tell them that your texts are taking a long time and see if maybe it's something on their end? I'm on Cricket and they use *228 to program so I guess I really don't know what Verizon uses but you get my point.
With Verizon it uses *228 option 2 or *22899. I have done that quite a few times with no luck. Everytime I ask Verizon all they want to do is tell me things I have tried already and get nowhere.

It's probably just a coincidence and Verizon is just having problems with their service right now in your area or something then. They are probably just too proud to admit it. Ha ha
HaHa. That's a good one. I hope your right though. It's kinda annoying. God forbid there is an emergency and I don't get the text cuz of the delay.

From my experience with cell phone companies, they all have trouble like this from time to time. Mine does it every once in a while and my buddy on AT&T, his does it ALL THE TIME even with the "all mighty iPhone", my brother is on US Cellular and same deal. My girlfriend is on Sprint and she don't get texts sometimes till the next day! It will probably work itself out. Good luck man.

Well, hopefully they would have enough sense in the case of an emergency to call you instead of text.

Hey guys,
So this might be a n00b question to ask but i haven't seen any other posts on it for the Evo 4g.
I can make calls, but not receive them. I can send texts and people get them right away, but i don't receive them right away, I receive all my texts at once an hour or two later, sometimes a day later. I checked my system time and it was supposed to be 9:30 am but it said 4:45 pm, then it went back to 9:30 am about 5 min later.
It seems like a radio problem because my network works fine with facebook and heytel.
I was wondering if anyone has had experience with this, is it a network issue i need to contact sprint or is it a problem within the phone itself.
Is your evo rooted?
I had a similar problem but it was when i had a blackberry but it wasnt all the time. Sometimes i got texts almost a day later.
*Usually*, it is a network issue. You can try updating your profile in the settings menu. Also, it is not uncommon to experience such things while roaming.

Ya it's rooted with Unrevoked running Riptide w Calkulin 1.8.0
Haven't had any problems with it until yesterday, been running it ever since it came out.
I'm definitely not roaming.
Updated my profile and PRL
Gonna re-update, pull the battery for a few, and call sprint customer care. I read somewhere people have this issue when their phone is in forward mode, random for it to all of a sudden just happen unless the phone got dropped or shorted out somehow.
I had a friend have the same problem yesterday but he just went through insurance and got a new phone.
So you're right it could be a network issue and spending $ on a new phone to gamble on having the same issue doesn't sound like something anyone would want to throw money at.

Give it a day or two, you definitely don't want to pay for something you don't need.
Also, back up your current setup, calikulin format all, and try flashing something else to see if the problem is ROM based.
Thanks Green. Good words brothuh, i gotta older version of Fresh i'm gonna try that out.
I haven't seen any new worthy ROMs with the gingerbread so staying clear from that for awhile.
Unless you have one you would recommend trying out.

Flash a different kernel. It shouldn't have an affect on your issue, but, I've learned that anything us possible with smartphones.
Posting & replying via the XDA Premium app
Thanks Doug, not sure how to flash just the kernel but i'll look it up and post the results later today. Thanks for the tips!!
I tried reflashing the entire ROM and no dice. Think it's definitely a network issue. Going to sprint today, keep you guys posted.
I had the same problem and was on EVIO 1.8. I reflashed my PRI and that seem to have solved my problem. I tried many things but after flashing the PRI the phone has had no problems and that was about a month ago.
Here is my post to someone who had a similar problem as you.

If you do end up posting on the Sprint site please do post in this thread as well...
Also it was just pointed out that there also is a Samsung support Twitter @ www.twitter.com/samsungsupport
(Please also contact there if you experience LOS)
If you would like to follow this up with a call to tech support, it will help. Try and get transferred to advanced tech support.

I hope your reliable source wasn't a Sprint CSR.
Those of us coming from the Moment were constantly being told that by Sprint regarding the radio lock up issue. They never did fix it. It wasn't until the devs at SDX got 2.2 onto the phone that the issue went away.
I have also found that tweeting complaints to www.twitter.com/samsungsupport during business hours will get a quick response, which results in escalation of real issues.

i just got off the phone with sprint and they told me that samsung pushed an update on friday to fix a delay in receiving text messages which has borked the internal antenna. that would explain why i only started having problems yesterday.... sprint will give you a ticket number and they will fix your phone for free at a store.
call up and get it fixed.

This is false. The issue has been going long since before Friday.
It will be fixed in the first update though.

Its not a showstopper and it doesnt happen on all devices. So if it happens when you get it use your 30 swap to get a new replacement. It hasnt happened on mine at all. Also there is going to be a fix... So, with all of that said I cannot think of a single thing that should cause anyone to decide not to get this and choose another phone. Thx

It is a 14-day swap unless you bought your device pre-launch.
This is a total show stopper, I have 2 of these and they both do it constantly. I cant even surf for more then 10 minutes without it happening to both units. I cant make calls, I cant receive calls, cant go online, cant use streaming music, cant use navigation. total waste at this point. I love the phone physically and its great when on WiFi but that's only 1/4 of the day. I am not taking a chance of getting stuck with a phone that I cant even make calls on. maybe I will try again once everything gets fixed but for now its not worth the trouble.

You have something seriously wrong with yours then. I've had mine since launch and it's done it twice. You should exchange yours.
I rooted my phone and got this for the first time the next day. Hasn't happened before that. Didn't even know what you guys were seeing until it happened. I just got a zero with a line across the middle of it in my top bar and my signal bar and data icon were gone.
Is that what people are getting also that have not rooted their phone? When I say not rooted, not the people who rooted then installed the stock kernal back on. People who never rooted in the first place. That is what I would like to know.
Mine did it once before rooting, once after.
And yes, it happened just like you described. I thought rooting and flashing Zedo v3 fixed it, but it didn't.

Cool, I hope it is device problem and not just a rooting problem. This way we can get a fix for it from Samsung, hopefully.
I have it on good authority it will be fixed in the first software update from Sprint. No idea when that will be though. It's not a rooting problem.
I surely hope this topic hasn't been made... I don't want to be that guy.
Short and sweet... I'm rooted (that MAY not have anything to do with it)
I got this phone launch day... It worked perfectly. Not saying this is the reason why but as soon as the Iphone 4S was released my phone started failing.. Essentially what it does is give me a fast paced busy signal when I try to make a call. Sometimes I have to attempt to make a car 15 times or more. Of course that is annoying but people also get the same signal when they try to call me. Since I'm in sales that is a huge problem.
I called Sprint, the local store. The lady told me that while OG EVOs were having that issue I was the first SII. She said sprint was currently upgrading (and I read stuff in the news to back that up on a national level).
So after receiving no help from the local store I called the 1800 sprint1 stuffola.. They had me go through the whole ##xxxx## stuff. After doing that and it not fixing the problem they suggested I go to a sprint store and have my phone replaced. Now I, don't want to do that. I really don't want someone else’s phone and I just have this thing.. Where I don't want another phone (even though it will be an SII).
Now, I have an airwave at the house and I have absolutely no problem there. Calls come and go as they please. Which makes me feel like it isn't my phone. Is there anything I can do before I go and replace my baby... I really don't feel like going through the whole unrooting process and getting rid of the triangle before I go in there...
I've done PRL updates so that isn't it.
Not sure, but maybe try flashing the new modem...
Bobby O'S Epic Touch..
I had issues with busy signals and calls not going through also....until I turned off Google voice from my computer. I was using Google voice and groove ip to make calls over wifi and once I turned wifi off my phone was useless. If you aren't using GV then I have no clue lol.

Ok i am not new at flashing and android, but i am stumped. Here lately I have been getting the dreaded circle with the line through it.. I have flashed radios through Odin and recovery, reflashed roms in both methods and even Kies... and also done a nandroid restore of a rom before this happened. When it finally gets connected (after 10 minutes, sometimes longer) i have not problems until i reboot and it and i have to go through the same process of trying to get signal.... any help would be appreciated. or point me in the right direction... i am currently running stock unrooted 2.3.6...
I have also tried my sim in another phone and my daughters sim in mine same thing with my daughters sim.. just throwing that out there..
*bump* no one have this problem?
hmm. flashed Darkside and it seemed to have an effect on it... took only 3 min to get signal... weird!!!!
going to reboot in a sec to see what happens

I have spoken to top tier support multiple times. The Field Engineering teams are involved now. Its unique here because on their coverage map I am in Excellent area. I'll have 3-4 bars show 4G yet I do not get a data connection. I called back and should be hearing back by the 17th. My ticket has been open for months... Afraid my device is defective or only works half the time. I am very low on apps and never install much. This is a bad situation for me. House phone and work device.
yes that does suck bad!!! but it is weird, in my case... just one day stopped after a reboot... my other devices work fine...

Exact same thing here. Stopped randomly first day... totally intermittent after! It was ironic because I had held off grabbing the GS2 because of Samsungs GPS issues with the Vibrant and first week I had my GS2 I was extremely happy. Rest is history I guess. Hope yours starts working again.
Having a very strange problem with my S3. I've noticed it at home more than anywhere else but basically what happens is that if someone calls me, the phone doesn't ring on my end but I do get a voicemail notification after they've left a message. Then when I talk to them, they tell me that on their end my phone rang once or twice and then went straight to voicemail. And my phone doesn't show any missed calls so obviously, my phone never detected that there was an incoming call.
BTW, it doesn't happen all the time. Sometimes the calls come in just fine.
I've checked my signal strength and it's always between 3 and 5 bars. I've missed more calls than I can count because of this. Some of them were important calls.
And I don't have any problem making outgoing calls or using the data connection for anything.
Any idea what's going on?

Is it just certain contacts? You may have them set to go directly to voicemail by accident. I can't find where the list is in the phone though ahah, I can see how to add them to reject list though.
EDIT: Found it go to dial-pad and hit menu and then call settings and you will see call rejection see if you have anyone in there.

Nope, has nothing to do with who's calling. Sometimes a call from the same person will come through but ten minutes earlier it didn't.
Ive had similar problems in the past. Turned out the phone signal was going up and down. When it was up, calls came through. And down, well duh. Either way, try a new radio. Maybe it'll hold a signal better. I've heard people complaining about H1, but cant say either way myself. Just a suggestion.

My baseband version is UCLG1.
btw, I never had this problem with my iphone 3GS which I had for almost 3 years.
I have to say that even though on paper the S3 blows the iphone out of the water, for pure functionality without problems, the iphone is definitely way ahead of the S3. I'm pretty much stuck with it for the next two years but I have a feeling that if things stay more or less the same in the cellphone market, I'll probably be switching back to iphones after my contract is up. The S3 is very cool but I've just had way too many problems with it that I never had with my iphone. My iphone just..........worked. With my S3 calls don't come through, I'm constantly having to force stop apps so my battery doesn't drain all the time (and even then, half the time the battery drains like crazy no matter what), the visual voicemail is sketchy as hell and doesn't work right half the time, the data connection even when it shows a strong LTE signal is often very slow and times out a lot, and a bunch of other misc. annoyances that I never had with the iphone. I wouldn't say I'm sorry that I bought the phone because I wanted to try out the latest and greatest but when my friends and coworkers have asked me about it, I've been telling them they'll be better of waiting for the iphone 5. Sorry to vent but overall, after having it for almost two months, I've concluded that I'm very disappointed with this phone. Sure, I can do things with it that I couldn't do with the iphone but f*ck me, at least with the iphone I could do basic sh!t like receive phone calls and check my email without the connection timing out all the time.

All of the issues you listed are not really S3 specific because I have had none of them and have had my phone since release. Apart from the video voicemail which I can't comment on because I have never used.

I've had my I747 since release in June and not experienced any of these issues. Over the years with Blackberrys and the Galaxies I found most problems result from variances in the network. Signal strength, carrier software and even where the phone is in the house. I dislike much about the iPhone (I do have a 4th gen iPod) and much prefer the openness of the Android OS and NO iTunes. Hope things with S3 get better for you.
Still having the problem. It seems to happen most often when I have LTE enabled. I disabled it using the method mentioned in another thread where you remove the sim then enter a code which takes you to the menu where you can choose what to use.
When I had LTE disabled, it didn't seem to miss as many calls. But when LTE is on, I miss a crapload of calls. I'd leave LTE off but for some reason it keeps re-enabling itself every few days so it's turning into a massive pain in the ass.
Any suggestions?
I have the same issue as you, but I'm on Wind Mobile. This issue happens intermittently anywhere between 1 to 2 days, my phone will stop being able to receive calls. It's very frustrating and Samsung is really no help. After two attempts on trying to "repair" my phone, they have failed each time. The only thing they did was they ran a "RF Test" and everything passed, they said. So they re-flash my phone with the same ROM - again and again.. I told them, "This is my second time sending it in, and you guys are redo'ing the same steps as the first repair. You don't need to be a rocket scientist to know this, but wouldn't you think when you send me back the phone - the issue is still going to be there?!" ... And sure enough, when I got the phone back, I was still unable to receive calls..
So I took matters into my own hands - I flashed it with a older release stock rom and I tested it for 2 weeks, and it was able to receive calls. When I flashed with the earlier release, it also flashed the baseband. Either way, I should not be prevented from using the up to date software! This is a Samsung issue but if you ever tried dealing with them over the phone, it's painful. They said they would send me a REFURB replacement - (believe me, I tried fighting for a brand new phone, since I paid for a brand new phone and this issue came straight out of the box - it's not even my fault to begin with!) it's been 3 weeks and I still don't see any phone replacement nor did I receive any mails from Samsung.
Btw, Galaxy S3 is the phone I have.
If you discover a permanent fix for this issue, please let me know. I've been searching but no luck.
Thanks!
UPDATE: it's been over a month and I still don't see any phone replacement nor did I receive any mails from Samsung. So I called Samsung today after a month and 2 weeks. They said my replacement have been cancelled. First they said it's approved and requested me to send in my receipt for the phone. I had done the the very moment I hung up the phone from when they told me my replacement was approved (that was over a month ago). They want me to sent it in again to Samsung so they can "test". This is just ridiculous and getting out of hand. Does ANYONE have a fix for this????
Other forums are saying this is a wide spread issue...
are u missing imei, or just the problem you descibe... try flashing the latest modem... maybe yell at it while it flashes...
Nope, just having the issue I described... IMEI is exist and is valid.

Sorry for the late entry here but I'm also having the issue. aftershocks, and anyone else having this issue, open battery stats - what does your "mobile network signal" bar look like? Mine is mostly tan except for when I make calls, which then it goes green. I also have an HTC One X (AT&T model) and the bar's mostly green on the HOX.
I've flashed back to the original modem (UCLEM) to see if that helps and I'll move forward from there if not. UCDLK3 was the modem I was originally on when I noticed the missed calls. Here's the thread with radios: http://forum.xda-developers.com/showthread.php?t=1831898.
