horrible signal problem going on. - EVO 4G General

im having a really wierd problem go on with my phone. i have been using fresh's latest rom and i tried the Myn’s Warm TwoPointTwo. all of the sudden im getting a triangle over my signal bar saying that im roaming. my connection has gone to hell the phone restarts now randomly. i decided to do a nandroid restore back to fresh but the problems juts migrated even with wipes. i installed cyanogen and still. the wierdest problem is that when i send a message when im with full signal i lose all my bars! literally the moment i press send i go from 5 to 0 bars and its not a death grip issue because i have a cover on. it also gets to the point that the phone crashes and restarts itself. any help will be appreciated thank you. ill try and post vids of this soon

Its probably because sprints service is down something like that but for your random shut downs did you try to full wipe if still happens im not really sure

3G stops switching back after wifi?

This is a strange one. I have been using Fresh Evo 3.2.0.0 rom for almost a month and it works great. I wanted to try another rom so I tried the VirusRom... it was good but I liked Fresh better. So reflashed my Nandroid image and all was well.
But then I started seeing a lot of failed connections to the market and noticed that my 3G was not connecting. I live in Chicago so I am fully covered by 3G in this area, and even 4G in many spots. Usually when I leave a wifi area, the phone switches back to 3G almost instantly. But ever since nandroiding back to the Fresh Evo 3.2.0.0 rom, it only works after a reboot. As soon as I hit a wifi zone and then lose it, 3G doesn't switch back on.
4G and Wifi both work, but if I disable both wifi and 4g.. 3g doesn't come back without a reboot.
I've even switched off the Mobile network using the widget and the power button menu.. no luck. Only a reboot brings it back.
So then I even did the trick to get my PRI up to 1.40 and that worked fine. But no change in the behavior of 3G. When I reboot and 3G is working, it works great as usual. Just not sure why the switching no longer works. I even tried switching back to the rooted sprint stock rom.. same deal.
Anyone else having any issues?

yes, I have noticed this at times. Just happened to me. Failed connection when switching off 4g to 3g. Using fresh 3.2. But I noticed this as well on other roms. I had to reboot each time to get 3g working again. I also reset my data connection last night but it obviously didnt work.
I've been having issues with my 3G for the past two days. Similar story, I did and Nand restore and that is when it started.
I am getting an error code 67 everytime I switch from Wifi, 4G or even when I reboot to try and fix this. Usually if I let it sit it will come back, but the error message popping up is quite annoying.
Wish I had something more helpful to say, but I can just add that I'm having the same problems switching from wifi to 3g. Even after 3g turns on it will sometimes turn off again randomly and I will have no connection. I'm also running fresh. In addition my 3g signals are quite week. kinda a mess...
Weird. My phone did this today for the first time. The thing is, I've been on Fresh 3.2 for a month now, and I flashed the latest Baked Snack rom yesterday to test it out. It never did it while I was on Fresh, but today after turning off WiFi, it wouldn't connect to 3G for anything. No text or data transfer at all. After I rebooted it, it started working again, but my phone never did this while I was on Fresh.
I am having the same problem and I am using Fresh 3.2 as well. I did go to a different rom but then went back to Fresh's rom and that is when it starting happening to me. It will only pick up 3g now and then and even when it does my speed is super slow. Hoping someone comes up with a fix as I made my own post but no one seems to feel the need to reply to it.
Theories...
Same here. I'm on Baked Snack 1.7x
I know Fresh and Hero both use some of the same components. I flashed to Cyano and have had no problems with the 3G radio. It's very snappy switching on and off after wifi connects and disconnects.
I do know there have been one or two issues with the radio with people who are on the 3.28.651.x roms. (for instance, if you enable 4G then disable, sometimes it randomly turns off and on without you knowing until you restart)
So my guess is maybe the 3.28.651.x series is glitchy. You guys want to try going back to 3.26.651.6 and do some testing?
happened to me on stock. Had to reboot the phone to fix it.
This seems to be working for me today with no problems so far. I am wondering if a tower was down with Sprint putting up the 4g around my city. Will keep posted if it happens again but seems to be running like normal now.
This has to be network issues maybe the latest PRL.
Mine has did the same last couple days also on power on , it takes longer for 3G icon to kick in.
Signal flux has been occurring more then norm fast download - Upload speeds taking hit some parts of the day.

I am on 3.26.651.6 build and this was happening. I am no longer having any problems with this. I do feel this might have been a problem Sprint's servers were having. Seems like everyone started having the problem right around the same time.
It must be... Going to an older PRL didn't help, and there are a bunch of forum topics being created about this on other forums as well. Guess it's time to play the waiting game.
My issue is so bad right now even if I restart my phone, it doesn't even get data connection right away. 10 minutes waiting now and error code 67's keep popping up.
This just happened to me today. It took me awhile to connect the error statement to the fact the 3g didn't turn on after I turned off wifi. But I was able to press the 'data connection' button on the switchpro widget to turn 3g back on.

That is how I got it working a little bit last evening but as I said in my last statement it is finally working and has been all day. Not sure what the deal actually was as I did not change anything since 2 evenings ago. I am thinking that Sprint is doing something which is messing everyone up at one point or another.

3G in constant drop loop

Since yesterday my 3g has been randomly dropping and the icon will disappear as well. If idle the icon will vanish for about a solid minute, come back then drop anytime after 10-15 seconds. If I manage to keep a constant connection, the icon won't vanish. However it is horribly slow now.
This is my first cell with data and such so I'm not sure if this may be a naturally occurring 3g bug. It did seem to happen after a few days of several hours worth of shoutcast streaming. A few rom downloads as well due to my home net being broke too.
Been running jt's clean.02 and it's been rock solid. Tried flashing a few backups and some other roms from the site. I never flashed voodoo or a kernel either, just tried the modem update to make the di01 update complete. No change. This just suddenly started happening.
Any advice/help would be great!
I'm beginning to think the phone just decided to fritz out or something. Multiple wipes, permission fixes and restores. Only way to keep it close to functional is to keep pulling data.
I'm lost here and with no net and shady 3G, I can't get any good research done.
Sounds like a flaky radio. I'd try to get a warranty replacement, if I were you.

Galaxy Note losing data?

I've had my Galaxy Note for a few months now with no issues, all of a sudden last week it would show the H logo (but the little arrows showing data conntection would not move). but when I clicked on anything I would not have any sort of internet connection. I have to restart the phone to get internet connection again, I was on a new rom for over a week before it started happening, I tried 2 other roms since then and still have the same issue. I am about to try a stock rom and see if it still happens. I have also tried different kernels, is there anything else I should try? I show full bars for phone signal and still receive texts (not mms) normally when this happens but no data at all until I restart my phone.
Do you have any "power saving" apps like juicedefender? If you do, you may want to check your settigns as it could be disabled by said app (although you should be able to reconnect at any given time).
You said you have switched roms to see if the issue persisted. When you did this, did you full wipe or just wiped cache?

I've been having similar problems with a few of the custom roms (but can't remember if stock does it or not). In my case I'd lose data for about 5-10, then it would come back, and it randomly happened. I fortunately don't have to restart the phone to fix the issue like you do though. :\ Let me know if the stock rom fixes things!

I don't have juice defender or anything like that... even when i restart my phone, it takes forever for it to catch data, right now i restarted it, its been probably on for a good 3-4 min and still not showing any data.
I always full wipe when I install a new rom.
and it finally came on after a reset but usually data shows the second the phone turns on, this time it took it a good 5 minutes before the H appeared
I would suggest restoring to your first backup after you rooted your phone and see how it goes with the stock rom. Good luck!

[Q] 3G Dropping out/ Triforce ROM

Hello, I am using Sprint S4 with Triforce rom updated to 3.1. I have used the Agat and Ktoonez kernels with same result. What happens is i will have 3g service (bars) but the 3G icon disappears and i dont have service. 30% of the time i can reboot the phone and get it back but other times i have to boot into TWRP and wipe cache and dalvik cache and it will work for a little while. I notice it happens more if i travel but also when not. I have ODIN back to scratch and put Triforce back on but same thing. I was also having random reboots but the Agat kernel seems to have fixed that.
thanks
I would also like to know the answer to this....I live in Tampa and have the Negalite ROM and I notice my 3g will just drop in my house and this never happened before with my 3Devo......
To add to this i have noticed when this issue occurs and if i go into a area with 4g that works fine. But once i leave the area and it switches back to 3g it drops again.
Try ##72786#, that will do a full network reset. It won't wipe data or anything. It will however reboot a couple of times.

Just tried that, will this prevent it in the future or only if it happens.

I had similar problem and it solved it for me for good, however my problem was a bit different. Hopefully it clears things up for you also.
That didnt work, i was on the way home this evening and checked and had full bars but could not call or send receive data/texts.
