[LTE] Grey data connectivity

Is it me or do I seem to always have an issue with data and my phone. There are many times when I go to pick it up to use and the data, either 3G or 4G, is greyed out.
I've noticed it even if I switch my phone to CDMA only.
Any suggestions on how to fix it other than the obvious reboot or airplane mode?

Unfortunately, this might just be reception issues in your area. I have no LTE problems where I live.

That's what I'm thinking. The phone may just not know what mode to chose cause I'm in between the two.

I have to bump this thread. I'm sick of this. I can hardly ever send MMS messages when I'm on WiFi.
I'm not in a 4G area, that I know. I was successful in updating my PRL which I thought fixed my issue, but didn't.
It's not like I have no signal, 1 bar, -90dBm in my house. Even switching the phone to 3G only doesn't fix this. Rebooting is my only option, as turning on airplane mode doesn't help.
Does anyone else have issues connecting to data? I'm tempted to root, just to flash a new(er) radio, but I don't feel like restoring my phone.

Have you tried updating to the new radio?

Whoops! That's what I get for opening up threads in multiple tabs. I replied to the wrong thread.

Haven't tried a new radio, still would have to root it.
As for the wifi sleep policy, it's set to always. I dunno...

Yeah, that was my bad. I had multiple tabs open with different threads and posted in the wrong one.

I live in a spotty 4g area so its constantly switching from 3g to 4g and before it locks onto one signal it always does the stupid grey bar deal and sometimes it won't lock on at all even though I'm in a strong (3g) area. Restarting the phone works sometimes. All I know is that it better be fixed soon or this phone will be going back.

Yup, this is the issue I have. I can have strong 3G signal (all bars grey) but it just won't connect. Airplane mode sometimes fixes it, but I usually have to reboot the damn thing.

We have 4G here in town, but I live on the outer city limits. When I get closer to town I get 4G.

I know where I live sometimes I need to reboot my phone for it to change successfully from 3g to 4g... Another thing people suggest is toggling airplane mode on and off to make it pick up signal

I thought about taking it in and replacing it.... I don't have any reception issues, just this issue with the phone not wanting to get on data about 50% of the time.

fix for disconnect from 3g network

For anyone having issues with getting disconnected from 3g network. If you find that you are continuously getting disconnected from the 3g network on Sprint, goto your network settings and change your preferred network setting from lte/cdma to CDMA only. That should keep you on the 3g network without having to continuously reboot all the time. It's not a problem with your Rom I think it's an issue with the lte network. Being that it may not be up and running in your town. Yes they are advertising it but it is not online across the entire country yet.

[Q] anyone have this 5ghz wifi issue

Ok I got a 5.ghz router now and I tested it with my wifes 3gs.
Works like a charm . I go to setup mine ... It does not even see it .
Go through the standard stuff reboot pull battery yadda yadda yadda. get nowhere .
so i break down and call samsung .. well after a good time on hold they say my 5ghz radio has burnt out .... this sound fishy to anyone else ?
ps. Yep im still on stock JB man im getting old .. used to flash 8 times a day on my blackjack

Do you know anyone who has a router that you could test you device on? See if you can connect to their router with your device on the 5.0 band.

Same here. Dual Band 2.4 And 5 and I have no issues with either band. I'm writing this on my 5 band N router now. =)
May truly be a phone defect. Might want to back everything up and do a factory reset just to make sure some sort of software hasn't malfunctioned.

Mobile data not working

has anyone had the issue where their phone won't connect back to 3g data?
when I reboot my phone 3g will work until wifi kicks in. after I turn wifi off 3g comes back, I can call and text but will not download any data.
I have tried Odin back to stock. wiped everything including recovery. I have tried flashing every combination of modems and kernels. all same.
however one thing I will note. I have not been able to get a successful modem flashed in Odin. it keeps failing. so I flash in twrp.
I also wiped the activation data via ##732# or something like that. had sprint reactivate my phone too..
perhaps someone could shed some light on this?

I just got my Note 2 like 5 days ago and mine does the same thing. Its very annoying and its gonna be exchanged today for that and other reasons.
Sent from my SCH-I535 using xda premium

hmm. I wonder if it's network related..
is your phone stock?
-Wizzle

Okay here is the skinny. It is network related. My wife's stock s3 does the same thing. If you are in an area without lte and your phone under mobile settings is selected to lte/evdo/cdma it will connect to ephrd13. Which is enhanced 3g. When you come off wifi or a phone call sometime it will not reconnect. You can toggle data a few times and it will reconnect.
To solve this issue, under mobile settings I select evdo only setting being that I do not have lte in my area. There is no change in speed between the 2 3g networks.
This info is from self diagnosing the rooted note 2, a stock photon, and a stock s3.
I have had sprint reset the phones as well as the ##data# trick.

yeah I did the ## thing. however it came back. so someone from sprint called me to see if Iwas happy with the support and I told them I was still having data issues. He told me that he would put my ticket in priority and after an hour everything has been working better so far...
but we'll see

When I say evdo only I meant cdma only. Ehrpd13 is the handshaking 3g for lte. Some areas have lte in the towers but no ehrpd13 so the lte is not turned on yet. Basically ehrpd13 and lte are like cookies and cream lol.

The problem is my area does have it but at my house its very weak. My ohone wikl display 4g but it wont download anything untio it switches to 3g.
Sent from my SPH-L900 using xda premium

When the 4g network matures as it will the 4g will get better as the 3g.
You can always go to I think s4gru.com. That site shows when and where lte will become available. Plus they will be able to help you better there than xda.
As for sprint customer service, they are laughable at best. 4 people I spoke with didn't know what ehrpd13 was lol.

Losing lte on a call, then doesn't come back.

I guess T-Mobile recently updated my tower to lte in past couple weeks. I'm rocking some great speeds, but when I get a phone call it drops the lte and goes back to 4g.
It stays in 4g after I get off the phone and doesn't come back. I have restarted... gone in and out of flight mode. Nothing... when I leave the area and come back or wake up in the morning... then I get lte back again.
Any idea on this?
I'm rooted, stock, wanam, uninstalled knox and carrier iq btw.
Thanks for any assistance

You can't make phone calls on LTE yet with T-Mobile. Thats why it drops to 4g(HSPA+) which allows calls. Not sure why it would not go back to LTE, maybe a sim card problem or a phone problem. I do not have any problems with going from 4g to LTE after calls. I have wanam, no knox, and no carrier iq as well. Are you on stock rom or a moded stock rom. Have you just removed knox and carrirer iq on stock rom?

I'm stock. It could actually be a SIM card issue. I'm using the same SIM card I had from my old galaxy s. I had to cut it to fit the note. Hmmm.. I think that's as good as any place to start.
It could also just be this tower is finicky. Maybe it's not 100% up and running yet. Just wish it would lock onto lte after the call again. It's so choice having those speeds!
Thanks for the SIM suggestion. I'll let you know how it goes.

Is your lte connection stronger than your 4g connection. Because even though it may be faster it always goes with the most reliable connection.
If I know I have lte I just quickly go into dialer and change it to lte only and then back to lte/wcdma and it'll stick to lte afterwards

How do you change it to lte only from the dialer? Is there some sort of #* code? That might be just the temp fix I need.

Figured it out! Great trick... *#2263# ... select "LTE/GSM only".... then it connects to LTE.. do it a second time and select "Automatic" and the LTE sticks.

Couldnt one simply use 4G toggle app?

I tried toggling 4G... going into and out of flight mode... taking the battery out and restarting... going into GSM only and then back to auto select.. Nothing worked.
The method I described above apparently forces LTE only mode and somehow causes it to stick on LTE after going back to Automatic.
I've been doing it all day with great success. It would be nice if it automatic went back to LTE, but in the meantime this is a solution where there wasn't one before.
Sent from my SM-N900T using Tapatalk

It's because they just recently updated the tower. I was having the same issue in my area. I thought it was the phone and had it replaced. I finally spoke to someone at T-Mobile who knew what they were talking about. He said that it takes them months to tweak the tower until they get the optimum signal. Once that happens, you should go back to LTE after a call.
