Dropping 3g- annoying 1 and 2

So I leave wifi on, and the nexus holds onto to a useless weak wifi signal sometimes before switching to 3g. Annoying #1.
When I t run off wifi, I often have 3g not activated. Often have to either reboot or toggle plane mode. Annoyance #2.
Any solutions?

Pray and wait for next official radio firmware update or burn your nexus and get iTelephone.

Move to an area with better reception. Its not the phones fault at all.

please specify which phone you have. GSM/HSPA or CDMA/LTE?

I have cdma verizon phone.
To say "move to stronger area" is not an issue. If I'm in a solid 3g are, but a weak wifi area, phone holds onto slow unusable wifi instead of solid 3g"
Have 4g off
Is there a way to have wifi only connect if over a certain strength?
Will 4.03 make 3g radio connect more reliably and quickly. Absolutely cannot use battery saving app with this phone, as when I'm using 3g, and turn phone on, either have to wait 5 mins to get mobile connection or I get the greyed out 3g

I've had the same issue. It's only happened twice where I switch off wifi and it refuses to turn on 3g, didn't think about toggling airplane mode though. I had to restart both times. I'm thinking its software, at least I hope so.

Bullschit.
This is 100% the phone's fault.
I am having this problem today. Unfortunately I have not been able to reconnect to 3G all day. 4G, fine... 3G, nothing. My two colleagues with Thunderbolts are having NO problems switching their LTE radios off and running CDMA only. My Galaxy Nexus is the only one that can't find a 3G connection.
I'm starting to hate this phone more and more every day.

If you're in an area with poor wifi, why not just turn wifi off and utilize the 3G at all times?

Same problem here. I prefer 3G to 4G for battery life. For the first week or so, no problem - now I can never get 3G, but 4G works fine. I don't think its the phone - I think its Verizon and its network choices.

Connected to wifi usually offers better battery life in my experience however weak signal kills battery so maybe keeping it on 3g is the better solution here.
Any way of you strengthening your wifi signal?

I love my gnex, but I got a microsim card adapter in the mail, so I can switch back to my bolt when I need a reliable 3G radio, until google/samsung/vzw get the radio is fixed in the gnex.
It took months before the bolt's radio problems got sorted out. I hope it won't take as long with the gnrx.

I would just turn off wifi, but when I do, it takes too long for 3g to start up...and often it doesn't start up unless switch to airplane mode

what roms are yall running?
If you're running Stock, then it's the phone's fault and you should call VZW to get it swapped out.
If not running stock, then it may be the rom at fault.

Hows the radios working for ya??????

Ok, ready to pull the trigger on a Note 2 but having the ET4G and the issues with reception, Im a little hesitant on Sammy phones now.. I love my Epic T but low up and download speeds kill me. Im missing calls and its not showing up in my call log and texts messages too. I have friends who have the GS3 and some love it and some hate it. Two friends can sit side by side with their SG3 and have totally different reception, I dont get it. I hear the radio and antenna are the same from the GS3 but wondering if the size of the antenna in the Note 2 has changed and if so, is that change enough to help reception issues?
Any input from those who just got one would be greatly appreciated.

I haven't seen lte, but 3g is just as good as you can get on Sprint

I too have the epic touch, a d then the s3.
Although I cannot comment on note 2,because I don't have it yet, the s3's radio is much better than epic touch.
Instant gps lock and no LOS

I too have the E4G and have just been patiently waiting....I almost jumped on the SIII, but thought I would wait. I think GN2 is what I have been waiting for.
The missed calls (never ringing), daily lock ups and reboots are driving me crazy!

I picked mine up this morning, I'm very happy with reception so far, seeing a lot of improvement over my old epic 4g, and the download speeds seem a tad inproved in my commonly trodden areas

I cannot hold a steady 3g data connection. Network mode is set to cdma/lte/evdo and it keep bouncing on and off for 3g. just came from the Evo lte and that phone at the same spot can hold a 3g eHDRP or Evdo just fine. Going to see if sprint can reprovision this phone for me. If this is a normal thing with samsung phone then I have no choice but to return it.

Update:
Phone is now connecting better after switiching perferred roaming from automatic to sprint only. All my previous phone have no problem when set to automatic roaming. Well at least now my data is not dropping like it was. My real test by putting it on sprint only (home on samsung's phone) is to see if it will connect to LTE where's LTE is available. I will find out after work when I'm on my way home since I get no LTE connection here at work.

Anyone coming from the galaxy s3 miss the simultaneous voice and data? I can't believe this phone can't do it unless connected to lte.

How is the wifi? The S3 was weak on stock rom, then improved with AOSP roms.

Not seeing 4G on CM10

Hey guys, I recently upgraded to Mobilicity's 4G plan, but I want to know if is it just me, or is CM10 having issues with data connection? I'm not getting 4G speeds a lot, and it doesn't even show 4G by the bars. It just shows H+ and a lot of the times, it bounces around from h to 3G to H+ and back, then it'll go to H+ and start working. So, My question is, is this normal, to not see 4G by the bars, even though i'm on the 4G plan for Mobilicity. If that first one is a yes, then is it also normal that it bounces around from the H, 3G, to H+ for a bit then get a working connection on H+. And thirdly, is the wildly fluctuating speeds normal? Some times slow speeds and some times fast? And I don't think i Lost my IMEI, I see the number on my settings. And a Bonus question, I hear yesterday we were supposed to get the JB update, any word on that? Going to need to go back to stock and unroot the phone if so.

CM10s radio firmware just displays the signal differently. 3g-4g = 3g-H+

H+ is what the touchwiz ROM would call 4g...it also calls 3g 4g so cm10 is showing what you're really getting service wise. There's nothing different happening on your phone

Ohh okay. But is anyone else having random data speed drops? sometimes it's amazingly fast, where as others it's really slow.

Its not that its displaying it wrong. I believe it is actually switching between 3g and 4g (hspda+) data. It is probably a data tweak used to conserve battery because things like text messages don't need full hspda data. I've noticed that when im texting it uses 3g but when web browsing or YouTube, it switches to H+

3G - 4G handshake issues?

So Raleigh finally has a few LTE towers active, and with the help of Sensorly I know where those are.
Seems though half the time it doesn't connect. I know it's not a tower issue, as if I turn on airplane mode on then off it will connect to 4G just fine.
I noticed under settings there's the Sprint optimize connection thing. Turning that on/off seems to have no difference.
Is there a file somewhere that I can edit to change the default connection lookup time? Since LTE is different from WiMax, where you don't "really" have control over the 4G radio, I'm assuming there is a time-out feature. A specified amount of time it takes before looking for an LTE signal. If this is true, is there a way to edit that to speed it up just a little bit? Say going from 10 minutes to 5 minutes? I'm not worried about battery life. I can't kill this thing in a day anyways and I'm lucky to have access to power 7/10ths of my work day.
Also I'm not sure if this is related to MA7, Deodexed stock ROM, or what but I am having issues with coming off Wifi to 3G, and 3G not being active. Have to cycle airplane mode a few times to get it to work.

I'm rooted with stock and although my my phone switches fine between Wi-Fi and 3g I did have a little trouble switching between 3g and 4g. One thing I did that helped was switch the mobile network to 3g only then after it reboots switch back to the 3g,lte network, after reboot run a prl update. That may fix your issue. The problem may also be Sprint is still not done boosting the strength on the 4g towers and is still testing them.

I am having no problems going to 4g from 3g or 3g from 4g but they are pretty far in my area. That might be the problem is there not that far by you

Folks,
Your phone will connect to the strongest signal possible....if LTE is stronger it will connect and vice versa. When you toggle your airplane mode or power off/on it scans for everything at that time and will scan LTE and connect even if its weaker. As areas become more saturated it will connect easier
Edit:also turn off the sprint connection optimizer

I understand that. My question pertains to how long in between scans for LTE (I've read anywhere between 10 minutes and 30 minutes) and whetheror not that time can be changed on a rooted phone.
What exactly does the sprint connection optimizer do?

Well the note 2 scans pretty quick...id say <5 mins or so. I can leave my station where theres no lte and drive 1-2 miles and be connected. Once it loses lte it seems to reconnect in under a min. The connection optimizer scans available wifi hotspots and attempts to offload your data on wifi networks you have used before. Ive heard that it connects to wifi spots that you havenrt xonnected before but I havent seen this. It will cut your wifi on periodically to check and so forth. I uncheck mine and freeze it in titanium. ...personally I think it isnt needed and is a waste.

Ok cool. So you didnt notice any change with 4g connectivity with the sprint optimizer disabled?
I guess theyre just still working on the towers. My maket hasnt officiallyblaunched yet but close to 1/4 of the city's got connectivity.

I havent had any issues connecting to 4g with it turned off. I think here in Indy we are like the 40-50% or so and its pretty lit up.

Not true. Your phones data connection is set in a priority order. Wifi is #1 and overrides all, 4G is #2 (will override 3G and 2G even if it's a crappy 4G signal), 3G #3, followed by 2G as the final drop back if none of the others are available.

Oh I should've read that thoroughly. I see what you did there. First you were like it connects to the strongest signal possible then you were like it connects to 4G even if it's a weaker signal... What a way to contradict yourself kinda makes no sense which is why the confusion.

Phone wont connect to 3g when set to CDMA\LTE\EVDO mode

I have an interesting issue. My wife and I both have Note II's. I have a grey one, she has a white one. Both are on the latest Stock Rom and rooted, same kernel and modem revisions. Both phones on the dreaded 2000 PRL (Havent got around to flashing another one because we have an Airave 2.5)
My phone will not connect to 3g at all when I have LTE enabled. The other phone connects to 3G just fine with LTE enabled.
I have another friend that only sporadically connects to 3g with LTE enabled. If I set the phones that wont stay connected to 3G to CDMA mode everything is fine.
Any ideas?

Try automatic?

Does this happen around the airave? Airaves are known to cause a host of isues with rooted phones even with no custom roms
Sent from my SPH-L900 using xda app-developers app

The only way to get 3g when lte is enabled is when you lose lte sinal is you just want to use 3g set it to cdam mode only if you set it to lte

Cdma only or global
I was reading some other sites and threads after I encountered a problem almost just like this because I had switched my signal type while on AOSP.
I discovered that because our phone are global they have different connection setting and in short when you switch to either global mode or CDMA only, and try to go back to lte evdo the phone will roam constantly and will not be able to reconnect to lte. So while I was trying to fix my LTE I managed to force my LTE on but I wasnt getting any cdma or evdo. finally I got everything back to normal by flashing a back to stock rom and doing a hands free activation.

I'm also have an overwhelming time with 3g. I have no lte in my area but have tried both CDMA only and CDMA/let settings. My 3g is on and off within 1 minute intervals or hours at a time. I pretty much have no data connection 95% of the day, until I get home from work and can hit WiFi.
I'm just stock rooted on MC2 and also on prl 2000.
I've been on the phone with sprint for days trying to figure this out or get them to waive my ETF. I refuse to keep paying for service when I am not getting any. It's bad enough they don't have 4G much less LTE here, but I can't continue to do these sub par dialup speeds to no speeds.
Any other tips to try would be greatly appreciated. As sprint says everything is fine in my area...
Go figure.

Yeah, same problem here. Somehow after rooting the phone i completely lost 4G LTE connectivity. Now everywhere i go it's only on 3G or EvDo Rev-8 which sucks. I think the only way of fixing toys issue is to Unroot and go back to stock ROM.
After doing a lot of research on the matter that is the only solution right now to our 4G LTE catastrophe. :thumbdown:
