[Q] Data Network Mode on Froyo: Safe to turn off?

I have experienced that with such apps that disable data (i.e. quick settings), they potentially ruin your CDMA data speeds. I had to re-odin my Epic to get data back to normal. Well now that we have froyo beta's out there, I noticed the option to disable data network mode. Is it safe to do so without ruining your data?

I've used that option on this new Froyo about a million times without issue. I don't think it would hurt our phones since it's baked in by Samsung and not our devs here. If you have issues with it I'd be interested to hear about them but I say try it out because I've have zero problems. I'll do another speedtest tomorrow when I'm home in Minneapolis. I'm currently at my parent's and 3g is spotty and slow here.

Ah. Ok will do. I forgot this was a leak from samsung's Hq

My CDMA data speed has been destroyed and I've been trying to figure out why. I haven't been around wifi for a couple days and haven't been able to download a new rom to flash to try it. Any fixes other than odin?

According to speedtest.net app, 13 kb/s. That's absolutely pathetic. I've seen faster dial up. I ran the test 3 times to be sure and I have 5 bars of reception. With wifi on it's 4+ mb/s.
Edit: flashed a new rom to see if that would fix it, and no luck. Looks like it's time for odin once I get access to a computer.

i use froyos 3g toggle all the time and i havent noticed a major difference. but i live up in the middle of nowhere in new hampshire and i'm experiencing faster 3G speeds and i only have 1 bar as of right now. just ran a speed test and got 102.4 kB/s. i would definitely say there's something wrong in your case, i just don't think it's the data toggle based on my own experience. However, I could be wrong.

Roaming

I thought that if the phone can't get a sprint signal it'll roam?
I get absolutely 0 sprint service in the part of florida I'm in, but it doesn't even roam to verizon (which gets all bars here). It just shuts the radio off.
My friend with an lg rumor(I think that's what itscalled...its a sprint lg texting phone) gets no servicebut roams off verizon while over here...
What's wrong with the epics radio -_- I've been using google voie to text over wifi,but I need to make calls too. I keep getting "MISSED CALL FROM 555-5555" messages but my phone doesn't even ring -_-

You can force roam using Roam Control.
http://market.android.com/details?id=com.vuvuzela.roamcontrol
It works perfectly for me.

I can't buy it. Also, I shouldn't have to pay extra to roam for free...the phone should automatically switch instead of cutting the radio off. I can understan using roam control in areas where the phone hangs onto weak sprint signals and contantly switches back and forth, but there is absolutely no service here from sprint
The hero roamed full bars last time I was in a strictly no-sprint zone.
I hope cyanogen mod gets the mms bug fixed soon, ebecause I know thres a "roam" option in the cm menus. Atleast it was on the hero

I highly recommend Roam Control.

I would love roam control
I've wanted it since the developer came out with it in the epic forums, but I can't buy it.
Which is why I hope that now that froyo sauce was released, cm will move over to rc1 territory and it'll be a simple toggle in the settings...
Pure aosp with speed and force roam built in.... :drool:

Try updating the PRL? When I roam it cuts off my 3g which is annoying but I still have cell signal.

I updated prl as soon as I updated to eb13
It wasn't bothring me that I wasn't getting roam, but I was on dk28 so I affiliated it with that modem since there were other bugs....but this is official froyo now so I figured a prl and profile update in sprint territory would've fixed it, but it didn't.
Unless its a hardware problem....... D:

dumb question.....did you make sure you phone was set to allow roaming?
Settings>Wireless and Networks>Mobile Network Settings>system Settings>Automatic.
btw, I use roam control because it allows you to force Roam Only so it doesn't keep switching in low signal areas.

I get "unable to parse text" whenever anything is tried with Roam Control.
Tried fresh install, reboots, etc. No change.
Edit to add, i'm rooted of course.

Yeah roaming is set to automatic
Is there a dialer code that might help with signal searching?
I remember when I first got the epic, ther was something about dialing *#*#something and there was a menu where you would tell it to check CDMA only becauseit would search for gsm....would that help?

Roam control requires root...just an fyi.
It works great here on the new 2.2 update. The phone also roams by itself and connects to data via 1x with a normal prl. Or with a fixed prl it connects to 3g

Do you mean you never have a signal, ever? During your day to day life at home and work...? Cuz if so, dude, srsly: get off of Sprint. If you just roam 24/7, they'll drop your account anyway.
You sound like you have really unique, mysterious circumstances keeping you both attached to Sprint and unable to make purchases on the market (which is even more weird).
Call me a skeptic, but I'm having trouble buying into your story. :/ If you want to play this game, you can flash a Verizon PRL (do we know how to do this on Epic...?), but if/when Sprint cancels your account, do us a favor and don't waste XDA's bandwidth on a "WTF SPRINT" thread.

Better signal unrooted

I bought my ns4g about a week and a half ago coming from a tbolt on Verizon. I got it at 8pm and had it rooted by 9. I immediately installed cm7 and have been using every nightly. My signal was horrible. I had nothing at work and barely one at home. It also would barely hold a wifi signal even when laying the phone right next to my router. I've updated my profile and manually put prl 60679 on the phone and nothing improved. The only time I could get 3g was using the Verizon hybrid prl ( I don't have 4g here). I called sprint and updated the msi? And the lady said I was in great coverage at work and good at home. The signal was so bad in 4 ours of the phone sitting in my pocket doing nothing I lost 50% battery everyday. So this morning I unrooted to take the phone back to sprint for an exchange. I've been using it stock for about an hour and now wifi is good even outside my house and I get 2-3 bars most of the time. Is there any reason why this would be? I have owned about 90% of Verizon's android phones so I'm not new to this, I've just never seen this kind of difference between stock and rooted. I think I will wait and see if it stays like this or gets worse now and switch to the 3d if it is still bad. I switched to the nexus s because I love plain android, butit was so bad before I couldn't even make phone calls or send text unless I got lucky and it would connect.
Sent from my Nexus S 4G using Tapatalk

the only thing i know on the subject is i left my phone unrooted for a couple of days. never noticed a difference after rooting. seems to be many conflicting reports on signal issues when it comes to the nexus. i have generally lower signal (3g 4g wifi) than my evo. really hope its software related so i can get a fix.

Rooting doesn't affect the phone's radio.
Maybe the ROM was bad?

ive been watching my signal strength for a day and its usually around -86. my evo was always -90 or more

It could be the rom I just don't get it. I've never had a problem with cm7. I'm going to root and fund it stock rooted and see then maybe go with something else

damn i like soju 2.6 too. oh well stocks not bad either. i see theres 4 kernels to chose from and 2 are experimental
ok so i flashed my "out_of_the_box" back up and updated prl and profile and my status numbers are the same. i did notice tho that with soju 2.6 i was on evdo rev 0, and now back to stock im on rev A
now wtf? after i flashed a netarchy kernal (stable bfs 2.3.4) im on rev 0 again. what going on here?

Here's what I'm gauging my claim on. I live in a basement apartment so I get awful service anyway. But, on CM7 I can't make a call without it dropping, and mms is out of the question. On stock, I can almost always get through a call and mms sends no problem. I have an airave and its the same story on that. CM7 the mms just sits there with the icon spinning forever. Stock it sends almost instantly. I keep a backup of both and just switch between depending on what I'm doing.

My favorite quote "Engineers are educated beyond their intelligence." Ironically, I am in school for engineering

Now I have a problem. I rooted again and right now I am stock rooted. My signal is back to being bad again. So I can either remain stock or switch back to Verizon or go with 3vo. I came to sprint just for this phone so I can root and play. I don't know what to do. I have 18 days left until my 30 is up...
Sent from my Nexus S 4G using Tapatalk

I rooted a couple days ago, haven't noticed much of a difference in signal strength practically... BUT my time without signal went from 1% to about 8% . Obviously battery life suffered somewhat.
Currently I'm on EvDO rev. A.
Will continue to post updates.

So I have switched to the hybrid 00001 prl for now and I get decent signal, eve get some at work. I figure if I'm going to switch tithe 3vo in a week I won't go over the 300mb roam limit. Its a shame too I like this phone, I just want something j can play with.

Why aren't I getting LTE?

According to this map http://ltemap.org/tmobile there are LTE towers in Carrollton and Garland, which means I should be getting LTE in the Plano area. I have the .33 radio flashed, the APN right, and set to LTE/GSM but I'm still not getting LTE? Do the tower signals really not bleed into Plano or am I not doing something right with my phone? I'm on Carbonrom 5/25 nightly. Thanks

You also have to enable LTE on your nexus, unless you jump through hoops, it has to be done every boot because the device resets itself to wcdma preferred. Dial *#*#4636#*#* and hit phone information. Then scroll down until you see a pulldown with "wcdma preferred" and change it to gsm/CDMA/LTE. It then will take good 5 minutes to connect usually. After that initial long time, it usually connects pretty quick if you lose signal.

Maybe they are still testing? Back in March I ended up enabling LTE on my nexus because DC area was supposed to have it up and I got LTE at my house, just no bars to go with it. So when I would test, it was around 7mbps or would drop the signal, would not work anywhere else really, and was spotty. I disabled it and the. In early may decided to try again. Now, anywhere I go I get really good LTE speeds, signal rarely drops. I would say that I'm connected about 95% of the time, and I'm up and about the city a lot, or Virginia even.

You also need an LTE enabled SIM, and if you already have one, you may need to sort things out with the carrier. I know some my American friends had trouble getting LTE to work on AT&T using Blackberries imported from Canada, even though they had LTE sims and LTE plans - they had to call up AT&T and jump through a few hoops. Also at least on AT&T and Canadian carriers, prepaid plans aren't allowed to access LTE (lame) so if you're on prepaid that could be the problem. I don't know anything about TMo, but I'm guessing they may have similar bureaucratic BS to AT&T.

GS4 data very sporadic

My s4 data is bad to kick off and back on. It has done had since I first got it. I have 3_g at home and it's very solid signal, I never lose signal in fact i keep 4-5 bars but data kicks in and out all of the time. My old phone was very solid never lost data signal ever. I have tried the 3 different radios and several ROMs but they all do the same thing? It doesn't show roming and it looks to be on sprint solid. I know I've read about losing data due to flashing but mine works fine then it doesn't work, off and on, off and on all of the time... Rebooting sometimes brings it back, switching radio off will sometimes too but sometimes I just have to walk away for 10-30 min and it'll pop back up... any ideas?

I will assume that you have updated PRL and profile. If not, do so. If that does not solve the issue, call Sprint to see if thry are working on towers in your area.

Yes I did update profile/prl as well. I have a second phone we keep in the house (as my house phone) but it keeps data signal just fine never drops either. I haven't called Sprint I may try that but I really think its buggy firmware

Hope the problem works itself out. One last suggestion would be a factory reset (that is if you didnt wipe data through rom flashes). Doing so can potentially fix a lot of different isses....maybe this as well. Good luck
