I get the problem occasionally too but fixes when I do a hotboot

I've been having the same problem for the past week. Just started out of no where. Sometimes a reboot doesn't fix ot. Completely stock here.

Yes I get this several times a day (10+ times). I've found that either going in and out of airplane mode, or more easily, attempting to place a call (doesn't matter if it connects, I usually just call my voicemail and hang up immediately) fixes it. I had this issue much less frequently with the GS4 and I had a previous GS5 that I turned in on warranty for an unrelated microphone issue which had the same problem. I live in a big city if that matters at all as it's possible it's a network issue (I often go into buildings/elevators where there is no service which sometimes seems to cause it when the phone tries to reconnect to the network).

I've found that a little bit of tape helps keep my data from being loose.

Hard to say since you gave us no details about your phone configuration. What is your OS version? One of the bugs that the 4.4.3 update is purported to address is frequent data connection dropouts. Sound familiar?

I figured it was because of network upgrades. I just got VOLTE in my area so that could explain it.

Wifi has this weird issue where it wants to scan my home network even though its connected a million times to it. Almost like it forgets lol. I usually have to disable then enable it; not a big deal i guess but still a bug for sure!

Mine does the same but after I wake the phone I have no problems. Maybe a 3 second delay reconnecting.

Release notes would be great. Photon WIFI/VPN is putting out extra packets which are then blocked by some routers. If the wireless router is used as a router and not an AP and IP6 is disabled, the problem seems to be corrected (i.e.: no reconnection failures in over a week when it used to happen every 2/3 days. See motorola photon forum for more details.)
My wifi seems to work pretty good at work and at home. I havent noticed the phone constantly scanning but I havent been looking for it either.
as of today my phone will not connect to wifi at all... release notes and date would be very much appreciated.

Me either always works and works great, also pretty fast as well. My issue is the voice/3G radio locking up and then the phone reboots.
so it seems some are having a WIFI issue and others voice/3G... rather odd thing going on there.

LFB network bug

I've recently noticed a weird network bug on LFB. If the phone loses signal (on subway etc.) with data on, when signal is available it acts as though the SIM was refused by the network continuing to display Emergency calls only. If I turn data on and off it gets weirder (see screenshot).
The only way to fix it is too reset the radio, with flight mode, or *#*#4636#*#*
It's definitely not a hardware fault since, as you can see it still can connect to the network. It just acts as though the connection was refused (or alternatively does something weird that causes it to ACTUALLY be refused)
Anyone else experienced this??
The phone is an original BTU using unmodified LFB on China Unicom

Are you able to set/receive calls or send/receive SMS? What about USSD codes to your provider?
I've already read about other users complaining about this issue, I guess it's a software-bug in the display.
No. I'm not sure if HSDPA will work in the example pictured. I was in a hurry to make a phone call so just quickly snapped the screenshot then reset the modem.
Messages will get service unavailable. Incoming ones don't get received until I reset

Yes, I've experienced the same thing a couple of times since LFB on carrier Telia in Sweden.
It reminds me of the phone/modem problems with the SGN which they never fixed before I sold it.

You can flash DXLF3.. It works so much better than the LFB radio.

Beijing.
Well 2G is okay. But it sometimes will lose it briefly in the transition from 2g to 3g.
Only Beijing subway line 4 has China unicom WCDMA coverage. the others are limited to 2g at best (except the overground lines, but even they are patchy)

Having updated to the stock LFB ROM and modem (UK, unlocked, unrooted), I'm really perplexed about the behavior of the phone data reception:
(a) 2 weeks ago, I tried using data connection in a friend's flat in Balham (London), could not get ANY data connection all weekend.
(b) Last weekend, data was consistently perfect and fast anywhere in the same flat, all "H+" 8Mbit and lovely.
(c) This weekend, same place but NO reception again, not a saussage. Voice phone worked fine, just no data at all.
And, yes, I've seen "emergency calls only" sometimes even when there is apparently a strong signal.
Back home again (Portsmouth), phone works fine.
On the plus side, battery consumption is wonderfully low!
Can anyone explain what's going on? It feels like the data connection is sometimes reluctant to "log in" or whatever is does! It seems to have a mind of it's own.
Thanks!
You may want to try another modem like DXLF3. It has better data network stability especially in cities or areas with faint signal.
I am planning to upgrade to the LFB, but i am not rooted. Want to be sure if i have problems with the modem signal, do i have to be rooted to install the new modem driver??
Thanks in advance...

Verizon's 4g data problem.

OK, I'm not sure if anyone one else has or is experiencing a data connection problem with Verizon's 4g toggling off and on. I know I "was" and this is my theory and it has actually worked for me but first let me start from beginning. I got new tbolt because having this issue, I rooted and install ROM and everything seem as it was fine until I decided to connect to myverizon app and as soon as I did I started experiencing the toggling off and on again. So I decided to un-install myverizon app and reflash radio again and sure enough everything fine now. Well like I said just my theory but I think if u log in to myverizon app its causing this data problem. Inconclusion if you un-install myverizon app and reflash radio you shouldn't have any more data connection problems.

I constantly have to log in to My Verizon app. It's just part of how the ROM that im using works. I'm running Jellyblur 1.3 and have 4G data drops without even moving my phone on my desk at work. Considering I don't stay logged into My Verizon, I don't see how uninstalling it and reflashing my radio would make a difference. I love a good conspiracy theory though!

I'm saying don't use at all. Yes to update to see how much data u have used u have to constantly log in to update. What I'm saying is if u don't use at all don't even log in to myverizon. Give it a try... Delete myverizon don't re install flash radio again and tell me if your data connection is still dropping.

For what it's worth, I never installed the My Verizon app on any of my ROMs and only had it while stock, which was a year ago. I still got major 4G connectivity issues a few months ago like so many others. Made the phone damn unusable at times.
Yeah I know it was a frustration for me. Have u tried new radios? .19 radios

I went radio happy a month ago and flashed them like they were ROMs. Tried probably 5 or 6 of them. I even tried different combinations of CDMA and LTE radios separately. No significant changes although the .9 or .19 radios seem to work equally well for me.

Lost LTE

Hey guys I have been rooted for a while now but on Sunday I crack flashed a bunch of 4.2 roms and lost connection to 4g. I have replaced my sim card and re flashed the radios but I am now stumped. When I get home I will probably Odin back to stock but if you guys have any suggestions I would appreciate it.

Just wanted to know if there was anything I could try in the mean time.
Sent from my SCH-I605 using Tapatalk 2
go into settings/more settings/mobile networks/network mode, then toggle lte/cdma and see if it brings 4g back up. If that don't work you can try a factory reset, still nothing then odin back to stock.
Yeah tried all of that. Looks like I have a date with Odin tonight.

Restored via odin and still no 4g. I'm at a loss. Could I have burned the 4g capabilities?
did you get a new sim from vzw? i know you said that you "replaced" it but was that with a new or used sim? also might want to power device off and make sure the sim is seated properly.
also are you getting 3g, 1x, or any data at all?
I finally got it guys thanks.

After all of that fighting the system, changing the sim, reloading stock the sim holder is sort of wide and the spring forces it just a bit off of the contacts I adjusted it just a bit rebooted and got 4g back. Always check the stupid things that it could be first. Lesson learned for the 10th time. Though I checked it multiple times before resorting to a system restore so who knows what caused it.
Always check outside before working your way in!

Broken mobile network connection

Ive spent days trying to solve this so I figured I would post something here and hope for a little assistance. After flashing a rom I noticed I had no mobile network connection when I tried to make phone calls or send texts but my lte connects and works and I cannot figure out how to restore my connection. I flashed back to my stock backup and rebuilt my nv data twice and I flashed my stock mdk tar and still have the same issue data works but calls and texts tell me "no signal found for mobile networks". If someone could give me some help it would definitely be pretty cool.

This happened to me once. It happened by flashing an AOSP rom that set CDMA subscription to NV by default. The only fix would be to flash a AOSP rom and then check network settings. Make sure RUIM/ SIM is selected in CDMA subsription and not NV. These network settings cant be changed on TW builds. Plus make sure CDMA/LTE/EVDO is selected. Hopefully this is what happened and solves your problem.
Edit: also make sure roaming is set to automatic.
