it's both. i have no internet connection.. i just have bars sometimes full bars with no 3g/4g. and i can get txts and calls while i have the bars..
if i power off and power on.. then it will work again.. and if im in 4g coverage it starts off saying 4g.. that doesnt' last long, then it'll say 3g, then go down to 1x, then go down to just bars.. i'm beginning to wonder if it's my refurbished phone i got from the insurance company..i didn't have my new one for one day and bricked it so i didn't get a chance to see if it was the phone or not..
just recently, i have been sitting in the same spot, trying to find roms and stuf, and i switched from cyanogen to slimbean and it said 3g once.. but i can't imagine it having anything to do with the roms..
thanks for any help you may have.

I would recommend flashing one of the more stable ROMs in the android development section. If that doesn't work flash a sprint PRL.

what do you consider to be stable roms?
i enjoyed cyanogenmod10 and am using the slim bean now. it's ok
not sure how to flash sprint prl...
i searched and didn't find much..
offer any assistance on that?

Im in Dallas as well. Its not your phone. its the network. Right around the middle of December i noticed it starting to get worse.
Its actually back to pre network vision speeds. 4G at my office is less then a meg down. Month or two ago i was getting 4-10 megs down on LTE.
Ive also noticed my 3G speeds are slower then normal as well. Sprint said Dallas has been undergoing some network testing issues and hoped to have it resolved by the 16th of this month. So 5 more days.. But i tend to not believe what they say. TO much bad info from them too often.
FYI, happens on my EVO LTE and GS3..

Well, I had the same issue a couple of days ago. But the issue was not with the phone....it was with the signal tower. You should call Verizon and see what's going on. Sometimes there are areas where 4G signals are also weak. I spent one night at South Beverly Drive and Wilshire in Los Angeles, and I got no 4G signal whatsover. If you live by the area where there are lots of tall buildings, you probably won't get any data signals. So you might wanna check both.
My first Nexus would lose all signal at random, even if I was in an area with 4 bars of 4G. Swapping the SIM card out didn't work, so I swapped the phone out.
The new one works perfectly in a 4G area, but in a 3G-only area (like where I live), it will drop its data connection a lot. It keeps voice, but the 3G icon disappears. Switching into CDMA-only mode didn't help. Flashing the 4.0.3 radios didn't help. I use a lot of data, so I'm left wondering whether I should swap this phone out, or just give up on having a Nexus.
I don't experience any connectivity issues so far(I live in Fullerton, California), and my brother, 2 of my friends, friends' friend, my girlfriend and her little brother!
It started after the 4G outage... Could have that hurt my phone? I highly doubt it but you never know...hmmm to verizon when I get back home from vacation
EDIT: Been on CDMA and it seems to be working, low bars, but seems to be. Maybe its verizon's network where I am, ill check again tomorrow. Hope its working this is really making me sad I really do love my nexus
Could it be your modem/radio? I'm using a GSM nexus, but I had loads of signal drops on the KK1 modem till I updated to the KK6 modem

I was wondering the same thing. Mine has been sporadic since the outages while my wife's charge is rock solid. I have tried to lose a signal with her charge and it won't do it. 3g is awful on my nexus. It'll be there for a minute or two then gone. Really frustrating cause I love this phone

I've been seeing the same thing but it seems to only happen when I'm on LTE. Example...I just went out and was in a 4G coverage area with full signal. Around every 15-20 minutes I would lose all form of signal for about 30 seconds and it would come back. I've found that switching to CDMA only allows me to maintain a solid connection. During the period that I was experiencing the outages my girlfriends RAZR has been rock solid. Looks like I may be spending some time on the phone with Verizon tomorrow.

3G Connection is faster than 4G

Hi, I have had my HTC Evo 4G for almost a year now and I have yet to encounter this problem until now. I live in a 4G hotspot and have always enjoyed the incredibly fast 4G data speeds up until recently. Within the last week or so my 4G speeds have dumbed down to a fraction of that of it's original speed. My phone usually has all 4 bars of 4G filled and it still does but my download speeds are between 20kb-50kb /sec, and high quality video streaming is surprisingly slower than normal. My 4G speeds used to blow my 3G out the water but recently my 3G connection has been able to download faster and stream HQ video faster. I am using Cyanogenmod 7.2 I updated from the original 7.0.3 just a few hours ago hoping this would solve my problem, it didn't. I have tried restarting my phone, updating my PRL, and switching roms but no luck. The problem persists on HTC sense, Cyanogenmod 7.0.3, and on Cyanogenmod 7.2. So it can't be the rom, plus I've had Cyanogenmod for quit some time before this started happening. Any help is greatly appreciated if you need any more details please ask.
Edit: Oh yea I haven't gone over any data limits because I have unlimited, but to be sure I checked in with sprint and the confirmed that I am truely unlimited.

Welcome to Sprint, where dial-up speeds are completely normal in the year 2012.
Yea I know this is insane I actually think dialup is faster than my 4G right now lol. Starting to piss me off because my wifi sucks as bad as my 4G does right now. Its a shameful day when your 3G beats your wifi and your 4G...

I've been with Sprint for years and ever since I've got the EVO, the 4G service hasn't been drastically bad yet I can definitely relate to what Argutom is saying however I'm really hoping that after the realease of the Viper and all other Sprint phones with LTE technology this nonsense is corrected.
Well after finnaly being able to get out of the house I have been able yo ascertain that this problem is not a phone issue but a sprint issue. This is because after traveling to other 4G zones and using my phone in them I have had speeds that equivalate to that my normal 4G usage. Well I'm off to call sprint thanks for the help guys. I hope I can do this with

Tmobile data problems

Is tmobile doing things to their towers or something last couple of days my connection been a little slow and no my text message wont send now ?
I rebooted and now it seem to wanna send weird
ooo I noticed you were in jax. I too have noticed data acting stupid lately. my data will be fine,but come night time, it get slow. as slow as .2mbps. I used to be able to hit 22+mbps tops n 13mbps on average.
Yeaa maybe its in our area bro idk was going on but maybe itll get back to normal im also getting like 3 bars when i use to get like full bars
There are some troubles with tmobile network since they offer unlimited 4G. I had suffered from very low data speed for month. It was almost zero kbps or could not connect with 4G. However. Edge worked fine. My Data speed goes back to normal this week.

NYC and Data Coverage

So I live in the city. Right now I'm using MOAR v4.01 and I cannot achieve a connection other than 1x no matter where I am in the city. I had this problem on other ROMS so I don't think it's MOAR.
I was using the Anthrax Aosp rom a few months ago and noticed I achieved a 4g connection on the upper east side but ever since then I cannot get higher than 1x.
Is there anyone else in NY getting a 3g or 4g connection? Does anyone know what I can do to try to fix this? I am using the MD4 modem (had the problem on MB1 too) and update my profile and prl often. I am really getting frustrated paying for services I can't even use. I am hoping that I won't have to unroot and reset my flash counter to bring the phone to a sprint store.

I'm nowhere near NYC (in fact, Southern California is pretty much as far away as you can get from NYC without going to Alaska or Hawaii), but it sounds like Sprint might be updating their network. I know in many areas (myself included), Data services were extremely crippled when they were installing 4G. I would regularly get 1x in areas where I would get decent 3G. Then a few weeks later, the 3G was back. Then a month or so later 4G was up and running (it's pretty nice here at my work desk). Others have reported similar issues when the network is being upgraded.
So maybe it'd be worth a call to Sprint to see what's up with them. A part of me doubts that most of NYC would be upgraded at once, but maybe in your area there's work going on. It's worth a (relatively) quick call.
Yes, I get 3g and 4g depending where I am. I'm stock rooted md4.
Had that issue once but update profile and prl over wifi fixed it for me.

I emailed them and they told me there is network outages in my area, but then the guy above me just said he's getting a 3g and 4g connection. Sprint really frustrates me. When I got my phone, it would say I was connected to 3g but after doing speed tests I would only get about 115kbps down. Now I'm using MOAR and it shows 1x and if I do a speed test on 1x its about the same. However, I used to get a 4g connection on 44th street and 6th ave but now I don't. I think I'm gonna go to the store today and ask them. If they tell me to bring my phone in I'll have to unroot it and reset the flash counter :/

Yes, certain spots in lower Manhattan I get signal but can't use the service. It just don't work. Text won't send or calls won't go thru.
Yes sprint turns on and off the 4g.

So I found out what was causing the issue. I went into the ##3282# menu and navigated to Others > HDR/1X Selection and turned it to Hybrid mode and now I can access 3G and I'm gonna test 4G after work.

(Q) LTE

Is anyone experiencing LTE problems? I have great Spark signal in my area, but this phone seems to go to 3g all the time. My other phones are always on LTE, so obviously coverage is not the issue here. I will unroot thru Odin and see if it's a root problem.

Not a root problem. Weird part is it only seems to happen to me in areas where there is really strong 4g, like in my house. At work, I am on a weaker 4g signal all day long without issues.
Try updating your profile and prl. Also make sure you have CDMA/LTE selected under mobile network.

I have the same problem. It keeps dropping my signal to 3g..even when it's on 3g sometimes it loses the 3g signal and reconnects to 3g.. the areas I go always have band 41 ...my previous phone was the nexus 5 and the signal was great...never drops connection like this...I thought it was only my phone as I haven't seen someone with the same problem in the forums. I'm in nyc area
Hopefully there is fix soon, it's very annoying to have this data issues.
Its not just your phone mine does the same thing at my work. I switch between multiple different band 25 26 and 41 towers as well as 3G towers. It occurs while the phone just sits on my desk. Theres a couple other threads discussing this. To my knowledge no one has any usable suggestions to help with this.

My Note 4 does the exact same thing. I'm in a fully covered spark area, my old s4 always connected to lte with about 10 meg download. Awesome data offensive note 4 gets 3 to 5 meg download.. sometimes only getting 0.01 upload speed. That's the only thing that consistently bothers me about this phone. Oh yea it also constantly drops lte... to 3g. Feels like it's data is going through a dial up modem. I'm going to check the Sprint forums and see if I can find any good info.
Happened once in one place i was. Lower LTE signal and the phone kept dropping it and falling back to 3g, while my gf Lg G2 kept the LTE connection. I'm thinking they need to tweak the radio software in a future update.

I've noticed that all the TriBand devices (Anything with Spark) switch to 3G for a bit then connect back to LTE/Spark. I haven't heard anything from work about this issue yet. I've also noticed its areas that have low Spark signal and high LTE signal.
My guess is it's a handoff problem. I will see all bars but LTE grayed out while riding the metro.
There is another thread touching on this too....I am having terrible LTE connection. My wife, who is an iPhone 6 user, gets 4 bars (or circles? lol) of LTE while I can sit next to her with 0-1 bars LTE or 3 bars 3G. I love this phone too much to complain alot about this but I am confident Sprint/Samsung will release an update to fix this.
The exact same problem occurred when the LG G2 got the spark update. It took 8 months for sprint to issues update that was specific to the LTE problem. I had to factory wipe before and after the update to get it to stick. The only difference is before the G2 was updated a toggle to airplane mode would bring the LTE back. That trick does not work on this phone. I will also add I drive alot at my job 6 hours plus a day. I go to the same spots to do paperwork in my truck. My Note 4 will not stay on LTE/Spark in locations where my G2 had a constant 10-15mbps connection.
