Airplane Mode to Reset LTE after phone call on AT&T?

AT&T customer service told me today that the HSPA+ network is capable of simultaneous voice and data, but that the LTE network is not (yet). She said that if you receive a call while using data, the phone will drop back to HSPA+. She also said that it may take awhile before the Skyrocket goes back into LTE mode. So she told me to put my phone is Airplane Mode for 15 seconds and that this would reconnect me to LTE if it's available.
Can anyone confirm this? I don't have my Skyrocket yet.

i have not seen my phone ever not have the lte signal up top. unless i get NO signal when im at my job. which normal for me.
and thats after calls as well.

i can confirm that LTE is NOT capable of doing voice AND data at the same time. So yes your phone will switch back to "4g" (or slower) during all phone calls. I don't know how long it'll take to switch back.

My phone used to'do this..after the 2.3.6 update it stop

This is correct. We were testing it over the weekend.
We even tried using Google voice to make the call and override the switch but the phone apk itself appears to initiate the switch from lte to hspa. This is not new info...it has been speculated that this would be the case.
I see some report the update changed this so I will test that tomorrow.
In testing the phone immediately switched back to lte after the call. The consensus seems to be that if your phone does not switch back you need either the new sim, reprovisioning on Matt's end or both. This seems to fix data connectivity issues and network type swapping issues that many are having

WIFI and mobile data handoff?

No ones addressed this. When turning on WiFi and WiFi calling it kills radio and can't be fixed until a reboot. Anyone have this. Also WiFi calling on this thing is horrible, and reception. Want to like this phone but probably getting a gs 2.

I have no wifi calling issues, at all.

So if you turn off wifi calling cell does not come back?
If wifi calling is on it should turn off the radio.
That is normal for wifi calling on the newer software phones. Even my Amaze with ICS does that too.
If you also have wifi calling set to WiFi only it will not get signal back properly until it is rebooted or in range of good enough wifi signal to re-enable.

I'm not seeing this either. wifi calling works fine for me and I haven't seen any problems with the handoff when I go out of range.
What ROM are you running? I'm using stock 1.53

It gets stuck trying to reenable mobile connection and I have to reboot

That is odd. For my phone it takes a few seconds to switch from wireless calling to regular cell signal when I turn off WiFi. If you toggle airplane mode on and then off, does your radio work? If not, check to see if your phone has the latest update for it already (under settings->about->software updates, I think). If that doesn't work, I don't know what else to try. You might have a defective unit. (edit: if you haven't rooted it and modified it)
Wireless calling does suck for this phone. I kill my wireless connection when a call drops and call back under good ol' cell reception. Heck, I can't even call voicemail under WiFi calling since the pass code dials don't go through properly. Then again, this is what you're trying to resolve, getting reception after disabling WiFi, so this workaround is not yet possible...

In response to the call quality, I do notice lots of "pops and clicks" in the audio when using wi-fi calling. I have seached the forums and this seems to be a pretty common issue with this phone. I've noticed it on Skype too, which was also a reported issue. Seems there are some bugs to workout on this phone, not too worried about it as its a new phone. Im sure some roms will fix these issues, if there isnt one out there that already does.

I'm using the latest TrickDroid ROM and I've noticed that sometimes the phone does not connect to data when I leave wireless. The wireless call quality is hilariously bad.

Calls going to voicemail

Hey guys. This is my second nexus5 ( first one had some screen bleeding issues) and I'm kind of upset. I love the phone..love anything nexus but people are calling me and it goes to voicemail. It doesn't always happen, and seems to happen more on WiFi than anything else. Happens rooted or not, Google voice or messaging apps installed or not, stock or custom ROM..
I swapped the Sim card, factory reset, unroofed/flashed stock..etc all that jazz and still happening. I'm probably going to go to my local T-Mobile store and swap this one out too I really like the nexus and don't want to have to get another phone but if this is an issue I just might.
Any thoughts? Have any of u had issues like this ?

Try forcing your mobile data into 3G mode instead of LTE for the time being. I had this issue as well where I was missing calls without my phone even realizing it got a call. The only way I knew was that the caller either left a voice-mail or my Google voice sent an email that I missed it. I'm also on T-Mobile, though I got my phone from Google.
Switching to 3G mode seemed to have resolved it.

I had this issue when I use to walk around with my wifi radio enabled all the time to snag wifi when I was on campus. Not a good idea. Something is up with the wifi to cellular radio handoff. I would lose the ability to get calls/ texts in a timely manner without a reboot. For now, Wifi is a no go. Gets buggy

Internet dropping

Anyone else have issues with the Internet dropping. Signal shows full connection to LTE, but I won't get internet until I toggle airplane mode or reboot. Happens once or twice a day... Do I have a detective unit?

I have the same problem. Mostly at work when I'm on wi-fi I have a weak LTE signal and I have to text I have to toggle airplane mode.

I've been on the phone with AT&T about this situation on two different occasions. Never happens on Wifi for me. They're sending me a new phone.

Yes!!!! I'm having this problem. I had it happen a few times last week and today it was completely bonkers. Its kind of aggravating. I'm considering swapping it out but I'm afraid it'll be the sane thing. So then I wasn't sure if I should wait for a software update.
No matter what, I can never stay away from android for long.

This happens to me on Wi-Fi after being on the phone. The Wi-Fi connection does not work while on calls. Anyone else having this issue?

Hmm my Wi-Fi was working great at my work. I come home and it didn't even see my network as being active/didn't auto connect to it. I've had the phone two days. A reboot fixed the Wi-Fi and it connected back up fine after. I'll have to keep an eye on it.

Ive had the same issue where it shows strong LTE signal but nothing works. Just yesterday it did and I had to toggle airplane mode on and off before it works. Ive had this happen now 2 or 3 times. Not sure Id call it a deal breaker but its annoying for sure.

Yea I feel the same way about it being a deal breaker or not. I don't think exchanging the phone for a new unit will help cause obviously we here are all experiencing it. I love the phone enough to not want a different phone, so I think I'll wait it out for a software update.

Yes, happened to me twice on LTE. Usually it happens in the morning after I unplug it from the charger. Had to turn on airplane mode then off to fix it. Annoying for sure.

I had this problem on the G2 running CloudyG3.
Sent from my LG-D851

Exact same issue here. Started a thread about this in the G3 section (prior to the AT&T G3 section being created) and still haven't received an answer there either.

Like someone else said, I had this happen on my G2 as well. Even remember it occurring once or twice with my Sony Z2. So far, only once on my G3. Toggling airplane mode off and on corrected it. So, not sure it's the phone.

This has happened to every phone I've had since mg iPhone 3g. I don't think its a phone specific thing for that reason. I had the same issue on my S3 and Note 3 as well. Its annoying but I haven't found a way to fix it other than toggling airplane mode.

Just curious, is the internet dropping out completely to where the icon goes away or is it just not loading web pages or stuff like that? I noticed that if that "allow Google apps to scan" thing is checked then it messes up the connection sometimes. Even if you uncheck it, it still may cause problems, so what I do is "forget" the network I'm signed into, turn off WiFi, turn it back on, and reconnect. That usually fixes it.

Mine did this a couple times over the weekend. Icon shows 4g LTE and looks normal but nothing works till I toggle airplane mode on and off.

I had the same thing happen on my s4. I thought it was an AT&T thing

I've had ATT for two and a half years first an iPhone 3GS and then a GS3. Don't remember this happening with them. And even if it did, it wasn't enough for me to go on a forum looking to see if others were having the issue.

are you referring to what I made a thread about? Yes there were times on my S3 the data had issues, tho yea I didn't wind up checking on here. But could that be bc the G3 actually tells you? But then again, the "no connection" thing just started on mine last night.

I have had this happen a few times over the past few days. Was waiting for a phone call, and it looked like I was connected. Had 4 bars,4g icon, and the activity indicators were blinking. But no data or voice was getting in. Needed to reboot to get it back.
FWIW, I didn't have this happen until I removed carrier iq. Since I did that a few days ago, it's happened probably 4 or 5 times. Not necessarily relevant, but it's the only thing I changed before it started happening.

[Q] Sometimes Not Getting Calls (Verizon Note Edge)

I have had the Note Edge for Verizon since launch day about a week and a half ago. Love the phone and everything seemed to be working fine until I noticed yesterday that I was not getting calls all day. I was in urban areas with full signal. Just voicemails here and there but never rang. Had some friends try to call me and it would ring 4 or 5 times on their end then go to voicemail, but on my phone never rang. After a reboot, i still had the same problem. After a second reboot it now seems to be getting calls. I have advanced calling 1.0 activated. Anyone else having this problem with the note edge? If so any easy fixes?

Have you tried the standard profile and prl updates.

Hmm, no I have not yet. I had assumed LTE phones automatically updated the prl. I am traveling now but will try that when I get back into my city tonight.

It seems there is no option to update the system profile. It also seems that you cannot do a prl update either by dialing *228 on the note edge. Every time I try it kicks me from the dialer with a message that says verizon Sim card stores this information and updates automatically. Not sure what else I can do. I have been getting calls since this incident. Maybe I'll just wait it out and see if it happens again.

It seems i may have found the issue. I called my phone from another phone and it didn't ring .. again. i turned off Advanced Calling 1.0 and tried again and it worked. Turned it on and called again, didnt work. It seems with advanced calling 1.0 activated, i cannot receive calls at times. I suppose i will leave it off, but this bothers me because with the note edge you cannot use the internet while on calls unless you have Advanced Calling 1.0 active. Lame.

I have advanced calling on and am getting calls.

I as well. RyanATF, call Customer Support & have them refresh your phone.

I also was getting calls about 50% of the time which is why it was so strange. I called customer support this morning. They checked everything and refreshed my phone. Level 2 support does not think it is my phone that is the issue. They sent the ticket to the VZW switcher engineers and will call me back on friday with an answer. They think that maybe the VoLTE network is the issue in my area as my phone is not having any connectivity problems.

There is a known issue with advanced calling.
