I've been having this problem probably once a day since I've gotten the phone where my phone will lose data signal while switching between 3G and LTE and the only way to get data back is to restart the phone. Turning airplane mode on and off won't work either.
Ive had that issue too..but most of the time it switches back n forth no problem

I haven't noticed any data problems until today. I am unable to connect to 3G. We do not have 4G in my area.
These problems are probably bugs in the LTE System.

why should bugs in the LTE system affect 3G?
the 3G our phones use is not exactly the same as standard 3G unless you force your phone into EVDO 3G via the ##778 menu. which if you are not in a 4g zone I would recommend simply for stability. The 3G our phones use is basically a layer between 3G and LTE as I've had it explained to me.. I really don't know much else about it though, sorry. I'm sure someone else here can shine more light on it however.

oh that's really interesting. thanks for that little bit of info. had no idea.
Same problem with it dropping data signal and never coming back without restart. At least now i know its not a hardware issue
I've had the same problem lately
~John
damn.. i was actually hoping this was a small problem with a simple solution... everything else about the phone is perfect except for this one problem.
Having the same issue here....when switching to cdma I get no 3G just 1X.....hope they find a fix soon

same here guys. call Verizon and let them know. I think it helps if a bunch of us make them aware.
I've had a ton of weird data issues with the Rezound. I get 1x where i should get 3g, i get 3g where i should get 4g and i get nothing way too often.
I've only had this happen once with the rezound. Shows nothing but bars, no data can be used. Sometimes switching to 3g or 4g in lte on/off helps.
Had this problem intermittently on both my wife's and my bolts, completely agree its just a lte being a new tech issue.
I've listened to a podcast on how the handoff works and its definitely not fool proof.

Im in Lawton Oklahoma and I'm not gonna c 4G till 2013 and I'll be pcs before that.
Now I access the ##778 menu in edit mode and what do I do to force EVDO 3G?

phone will reboot and you should get 3G back
This changes your network from eHRPD back to EVDO Rev.A. For LTE phone owners, eHRPD causes 3G to die (most of the time anyway) when the LTE network has problems. Get back on normal EVDO and you're good to go.
^ from Jntdroid on another forum (not sure if we're allowed to post to other forums here) I'm not positive on where he got it from, but this is a capability of all HTC 4G phones
I've had occasional issues with being down to 1X, but even that was only during nationwide 4G network issues, definitely get in touch with VZW about that... not that they have enough sense to fix anything *sigh*
Data Connection slow to Acquire (3G/LTE)
If I'm on the subway, or somewhere with no service, then come above ground, I get voice (full bars) but no data -- it could take upwards of 3 minutes+ for data to come back up. Any thoughts?
I've been losing my 3G service throughout my city, being restricted to 1x so many times lately where I SHOULD be getting 3G!(4G isnt available in my area yet). It's really annoying...perhaps nexus isnt theeee only one...
^should I try calling and programing what the user implied? Again, I am not in a 4G area...

Same issue as you. I live in a 3G area only and my 3G drops out a lot. Even a reboot doesn't get it back. Not sure what to do :/
Just got my HTC DNA (HTC Deluxe 6435) last Friday and I love it so far. I'm currently on a regional carrier Cellcom with shared 4G LTE services with Verizon. Only issue I'm running into is the 4G LTE and 3G transition when in a low signal area. When in the main part of the city I'll keep 4G at all times with no issues but when I go home is when it starts to annoy me. When upstairs I can keep my 4G signal but when I go to the basement it will go to 3G at <20% signal, which is to be expected. When I go back upstairs, which I know has an adequate 4G signal, my phone will not transition back to 4G until 1.) I'm in a very strong 4G coverage area >50% signal for at least 10-15 mins or 2.) by doing the airplane mode trick to refresh the signal. If my signal is above 25% it will always pick up the 4G with the airplane mode trick. It's not a huge issue at my house since I have WiFi, but what bothers me is when I'm on the highway streaming I'll keep 4G for a bit, but if it transitions to 3G it wont come back for some time when the whole highway is supposedly strong 4G coverage.
I've tried doing my own research for a possible fix but it seems to be isolated to specific devices and carriers with issues. One interesting article was the Sprint Wimax EVO 4G fix where you could dial the ##3282# number and log into the EPST to change the 4G rescan time interval, but these options are non existent when I log into my EPST. I was wondering if there was a similar setting that I would be able to change the 4G signal search options with my DNA or if it's something that is only based on my carriers SIM card programming.
Let me know what you guys think
Thanks in advance
I'm having serious issues with AT&T LTE in central Mississippi. The LTE network in my college down has been here for at least 8 months, but after ATT did some network upgrades last month, I can no longer access the HSPA network. If I make a call, it kicks me straight down to the EDGE network after a 30+ second delay. Same thing when I receive a call. As a result of the delay, I frequently miss calls and the phone never rings. The issue just started this month. Tried the new APN settings as suggested on other threads, and that just results in EDGE only access. I called AT&T and they forced me to do a full wipe and have them do a network reset. That didn't really fix the issue.
I am on ViperXL 2.0.0 with the latest radio (have tried the older radio too, no fix). Still on HBOOT 1.32 (I think, If not, it's 1.35) I've researched the issue to no avail as to another solution. If I could just use the HSPA network things would be fine, but when there is no LTE I drop to EDGE and the signal strength on the EDGE network here is 2 bars tops when there is 5 bars LTE, so I frequently have no signal when I used to have 5 bars. AT&T, as always in their valiant effort to cover their own butts, says there is no network issue.
Input and solutions welcomed! Thanks guys!
Just tried a sim swap with a friend. He has the s4 active and it makes the step from LTE to HSPA+ with no issues. However, his SIM in my phone still refuses to acknowledge the hspa network. Any suggestions guys? I'm running out of solutions. Problem exists on elegancia and viperxl ROMs.
This wouldn't be an issue except that I live in an area where there is literally at most one bar of edge once it drops the LTE.
UPDATE: After the new sim didn't work, I went ahead and relocked the bootloader and flashed the official RUU. No luck. It seems as though my HSPA radio has actually gone out and will not work.
Weird. I went back home and it works perfectly. But it didn't work where I currently live or anywhere along the 75 miles of travel. Regardless, the replacement HoX+ will be in next week.

I used to get LTE around here with this phone. Since about a month ago, things have gotten weird. If I use LTE/cdma/evdo mode or global, it just goes to 3G and never connects to LTE. If I go to LTE/gsm/wcdma, it gets LTE but no voice or text (which makes sense because Verizon isn't GSM). The LTE performance also seems really bad in this mode. It seems as though 3G is somehow prioritized above LTE, so if both are allowed it defaults to 3G. Manually switching APN's doesn't help. If I select "LTE - Verizon Internet" it doesn't connect to data and then after about 30 seconds goes to "EHRPC - Verizon Internet " and connects to 3G. Similar results on multiple different ROMs and radios.
I'm wondering if the SIM card could somehow be to blame. If I go to the Verizon store, will they give me a free SIM despite having CM on my phone? Don't care about warranty, phone is over a year old.
Are you on a custom or stock Rom? Is there a "Global" setting under networks? That's what my s4 uses. I don't think it could be your SIM cause if it was you wouldn't have any signal at all, not just 4g.
I just bought a LG G5 RS988 (Unlocked Model) recently and at first I had really bad connections indoor I said to myself this is probably normal.
Then I just saw that the phone seems to be only in 3G in the corner but apparently it's suppose to be able to get 4G.
I googled it and apparently it happened since the nougat update, many users lost the ability to use the 4G connection.
I'm I the only one with this issues ?
The phone boots, it stays on LTE, on the main screen then once you logon it switches to 3G WCDMA and stays there.
I have 3 options in the data menu tried all the ticks (Global) and it picks up the LTE 3G, the LTE/GSM somehow disable the whole data mode and the other one too, and the only way to get the phone to have a very good connection is on GSM only by accessing the secret DEV debug option :
*#546368#*988#
Select Field Test, Modem Settings, and RAT Selection, then selecting GSM Only.
Then my data bar goes full or 4/5 inside my apartment near the window.
GSM / WCDMA / LTE Auto :
LTE only : Makes it a X Disabled
LTE / WCDMA : Goes on 3G 2/5 bars
LTE / GSM : Goes on 3G 2/5 bars
GSM / WCDMA : Goes on 3G 2/5 bars
WCDMA : Goes on 3G 2/5 bars
GSM Only : Goes on normal G 4/5 bars
It's like the LTE doesn't work at all...
My experience
I've been researching the issue myself. I have found that it's either your carrier's network doesn't "whitelist" your IMEI number, so it won't connect to LTE, or your phone doesn't fully support all of the bands that are needed to connect. I have the RS988 and mine needs to have airplane mode toggled on and off or the carrier settings toggled to global and back in order for it to go to LTE. Otherwise if I try to use the LTE only setting, I cannot make or receive calls.
In other forums, they mention downgrading the OS to marshmallow to get LTE working again. I tried this... It was painful to perform and after a bootloop I finally got the phone to stock marshmallow. However, once I finally got it working and I made a call, it went right back down to H or H+ and stayed there.
My impression of the issue is that someone could make an app to toggle back and forth from the original carrier setting (LTE/GSM/UMTS) to a second setting (GLOBAL) and back to the original network setting (LTE/GSM/UMTS) after a call is made... This would be a simple way to fix the issue and get back on LTE even though it isn't perfect. This is probably your best bet to get on LTE because even custom ROM's don't seem to fix the issue for me.
It's a very bizarre issue. If anyone else has a better answer or more knowledge on the issue, please let me know.
If anyone knows why this phone seems to specifically have these issues, also please let me know.
