I just got a used LG G3 on Ebay the other day. So far it's been great (big improvement over my Galaxy S4, IMO). But I've noticed something strange. When I reboot or toggle mobile data, for the first few minutes, my 4G LTE speed is great. Then, after five minutes or so, it slows waaay down.
I installed the Ookla Speed Test app and am seeing it go from ~8-10Mbps initially down to anywhere from 0.2-0.8Mpbs after a few minutes. I've also noticed when it happens, at first I'll have 4-5 bars of LTE, but then it drops to 3 bars and the slowdown starts.
I thought it might be the ROM, but so far I've had stock 12B, stock 10B, rooted 10B and rooted 23C. All of them are having the same issue. I'm currently rooted and running the Eclipse ROM.
I haven't seen any other posts about this, but I did see a few about wifi switching, so I wonder if that may be playing a part.
Any help would be appreciated. Thanks!

I am on 10b rooted, and I don't have the LTE slowing down issue. Could that be your Cellular signal not stable in your area? If signal is OK, then it is probably a defect in hardware. Flash back to stock 12B and send it to LG for repair.

So my phone will not connect to 4G at all anymore. I have wiped and flashed Virus rom, Bloatless rom, Mik Rom, etc, and it may show the 4G lte icon, and then kicks off and goes to 3G. Also if I tell it to go to LTE only, it won't even show an icon at all.
I might be exchanging my phone out tomorrow anyway for some nasty backlight bleeding mine is doing, but I just wondered if anyone had any ideas. At first I thought it was because I removed some stuff I shouldn't have, but that went out the door the moment I wiped and flashed a new rom.
*EDIT* guess I should go ahead and point out that when it does "pretend" to connecto to 4G I have 3 bars, and have had 3 bars in this location since I got the phone saturday. So it isn't a signal issue.
Are you in a stable 4g area? I flashed MikRom tonight, instant 4g, plus, download speeds were in the 12-14mb range, which is as good, if not better than stock rom.

Yeah I just corrected my post. I have seen speeds near 30 down in this location, and usually have 3 bars. At worst I was pulling 10-12 down. This just started happening today, but I am not sure when. I didn't notice the issue until I flashed the AOSP rom. But I also flashed the Gingerbread rom where nothing really works that was in the dev section.
So all of a sudden my TB's 3G started acting odd. It disappears (the 3G icon disappears) unless I'm checking for updates, in which case it randomly reappears and seems to be doing work. Toggling airplane mode on and off doesn't help nor does turning the phone on and off. I can still get texts and calls but no 3G...
Tried everything (going back to ROMs that were backed up from a few days ago) as well as flashing that full new ROM/radio update. Wasn't doing anything specific before it went out...
Any ideas?

I didn't find that this worked at all. Only since the new radio was installed have I found 3g drop because I know I am in a partial 4g area. So for the time being I don't want to turn of the ePHRD. Has anyone else experienced this since upgrading radio and such?

Well I did upgrade the radio and this fixed the problems I was having. Getting great speeds now. But I'm far away from any 4G areas :/
I am having all kinds of problems today with the 3g icon going on and off. Sometimes when its on I still do not have data connectivity. Is this a verizon problem or just the new radio?
I think it has to do with LTE being prepped to roll out and more intensive stress-tests that they may be planning.
I've been having similar issues. I did the entire rooting process then flashed BAMF 1.5 and had little radio issues, but once I saw the 3G cut out a couple times yesterday, I flashed the radio that was already on my SD card. Since then it randomly cuts in and out, and sometimes requires a full phone reboot to come back. I don't think it's Verizon at all (at least not in my case), although my area is supposed to get 4G sometime this year.
I'm hoping the official OTA has a "better" radio that can fix these issues...since I sort of had issues like this in Boston when I was stock, but at home out in Central MA, 3G was as solid as ever.
Just an update in case anyone was reading this older thread--I continued to have signal issues for a day or two after rooting but I think I just had bad timing on flashing the new radio. I've spoken to a few Verizon customers (my mom included) and many of them had 3G issues the last couple days. Yesterday it was solid as a rock, signal better than I'm used to. So it probably was just a Verizon outage, testing 4G or whatever it was that they've been doing.
It's Verizon outages right now, lots of testing upgrading going on with VZW right now.
Ever since that data outage from 3 weeks ago, me and my wife's thunderbolts have had issues holding 3g/4g connections. The phones willswitch all the way from 4g to no data connection at all during various points in the day. I've tried the mr1 through mr2.5 radios and the issues haven't gone away. Talked to Verizon tech support multiple times and they said they've opened up a trouble ticket to see if its the network or our phones. We stay around Aurora and naperville which are full 4g areas but have had problems in multiple towns. So just wondering if anyone in the Chicago land area or the country for that matter is experiencing the same thing since that outage from a few weeks back.
For reference, I'm running cm7 with mr2 and mr2.5 on my wife's phone. But like I said I've tried different radios already.

connection perfectly stable in north side of chicago. i would simply return the phone to stock and exchange it. maybe a bad sim card. do you have problems sticking only to 3g? or does that work pefectly?
Its been acting up since before I installed cm on our phones. They haven't been the same since the data outage. We've had cm for about a week or so and before that we were running mr1 and mr2 with basic root.

If the phone is fine no need to exchange it just get a new sim. I got thunderbolts for my gf and her brother yesterday and their 4g seemed perfectly stable as I was rooting them the only thing I noticed was it did take a little for 4g to kick in after toggling via lte onoff

3g runs fine. And all of naperville and Aurora are 4g. North Aurora is not as far as I know. And I thought about the sim being bad but I don't think that's very likely for 2 phonesphones

Hey rygel411, does this sound like your situation?
1) Boot phone up fresh full reboot
2) Phone grabs a 3g/4g signal instantly and holds it for several hours fine
3) Randomly when you power on the display, you are missing a 3g/4g icon but have full bars
4) Checking under Wireless Network settings, Mobile Networks is OFF and WON'T turn on
5) Reboot solves the problem or Wait approx 2-4 hours and it solves itself randomly without doing anything
Does this sound like your situation? No 3g/4g icons and no data connection, and unable to turn data back on without a reboot or waiting a long time? Cuz if so this is exactly what happens to me and I live in central NJ. I always get perfect 3G signal on all my phones, even in my house. And my data speeds are generally good; 1500-3000kbps on 3G.
I am running MR2 Das BAMF Gingerstripped with Imoseyon's 3.4.0 GB Kernel. It IS related to Gingerbread, as my girlfriends Thunderbolt running full stock does not see this issue at all.
Similar but not exactly, both phones were acting up before I had gingerbread on them

I am in the western suburbs (Oak Park, River Forest) and I don't have any issues at all along the I-88 corridor out to Route 59. That's about as far into Naperville as I drive. 4G the whole way, no dropped calls.

Just wondering but are you on MR2? Because if anything its either that or the ROM, and I am more or less thinking its the radio. Could be why we didn't see this radio OTA yet.

I'm on 2.5, not sure of it's radio related or their network because I had Zero problems before with this configuration.
I was on 2.5. Then I downloaded the cm7 update that dropped a couple of hours ago and I was getting horrendous speeds with it, barely 1mbps. So I downgraded to mr2 and now I'm back between 7 and 13. I'm thinking about downgrading to the froyo radio and installing the cm7 compatible version with it.

This is exactly my finding, just in New Jersey instead of Chicago. I would like to see explicit details on what exactly happens when you folks lose your data connection, and what happens when you try to toggle certain settings (ie - plane mode, mobile network, etc)
Especially one particular detail. When you lose your data connection, is there a 1x icon in the notification bar, or are there NO icons next to your signal. That will determine if we're having a connection problem to Verizon, or if our ROM's/Radio's are the culprit.

I have the same exact problem as the OP. I live in Wheaton, work in Carol Stream and go to Chicago every weekend because my girlfriend lives there. 4G and 3G CONSTANTLY go in and out when trying to use them. The 4G icon diappears and then reappears. It doesn't switch over to 3G or 1X. The icon just disappears, displays full bars for a second in grey, 4G icon comes back in grey with 1-2 bars in grey and then goes green after 10-20 seconds or so. It's so ****ing annoying.
I'm running the latest CM7 build with 0223r radio. I've tried MR2 and MR 2.5 and have no luck. It's driving me nuts. It's not CM7 either. I was running rooted stock and it was doing the same thing.
I was getting symptoms like it was shutting on and off. Mine works fine with no changes in the Tampa area.

i only see this problem while tethering. if i try too many connections (open windows at same time) the 4g disappears for a second or two then it comes back. other than that (chicago north side) my 4g has been flawless. never switched to 3g either.
mobile connection issues on HTC Thunderbolt
Hi,
Did anyone ever figure out connection issues with HTC Thunderbolt? I have the exact issue that DaRkL3AD3R discussed in July.
My Thunderbolt just started doing almost the identical thing as he posted. Can't get on internet unless I wait, boot, whatever - almost identical to what you stated. Connection seems to be connected but it is not. I am new to "messing" around with my phone but this cuased me to root and boot but still on the Gingerbread os. It is driving me batty! It started about Mar 25 or so and I thought booting would help. Do you know if it may be the radio and are there other versions I can try? Someone mentioned new PRI version? Thanks for any pointing in the right direction!
Recently I have been experiencing, like many others, difficulty maintaining my 3g connection. It drops out at random times, sometimes staying off for 18 hours at a time regardless of reboots, flashing different roms, resetting my phones profile or reactivating my handset.
One thing I have noticed though, is the fact that my phone never goes to 1x. Ever. It's either 3g or nothing.
Do my questions. Is there a way to test the function of my 1x antenna if it is indeed separate from the 3g antenna?
If they are not separate, is there a way to reset it in some way?
I am currently running the latest radios from The good Capt. Throwback, my thought was to downgrade them and see if functionality returns.
Any ideas on how to proceed after that would be appreciated.

Jeezz...I had almost the exact same thing happen to me the other night...I had chalked it up to messing with a torrent app...but out of no where I lost my 3g connection, and it went to 1x...and the 1x would also cut out leaving me with nothing at all every 5 mins or so(the weird thing tho, is when the 1x connection would disappear I would lose the 3g symbol but in the network type it would list EvDo now...but I would not have any connection).
Naturally I was crappin my pants lol, I can't use the update profile feature on my phone, it's on Boost. So I went ahead and flashed the phone over again...Still the problem was there....So I did a factory data reset....still the problem was there....finally I went ahead and did the ##786# factory reset, flashed the phone again...Finally I was back on evdo like normal.
(BTW, my Evo LTE is now running 4.0.4 stock and there happened to be two of my friends here with their flashed to Boost Evo's, which were all running on EvDo with no issues...Plus I fired up my OG Evo 4g that is also on my Boost account and it was running on EvDo no problem whatsoever....so I knew this was some crazy issue with my Evo LTE)
I'm just glad the hard reset fixed it, I've been paranoid ever since though checking my network status, making sure I'm on EvDo lol.
Thanks for the responses. I've tried every reset I can find. Flashing the older radios didn't help either.
At this point, I'm just trying to figure out if the 1x radio is functioning. At least I wouldn't completely lose my data connection when the 3g drops out.
This happened to me when they were doing tower work in my area. Lasted a few days then I had 4g in areas I never did before.

I can only hope that's the case, Thick. It would be the best possible outcome.
By the way, thanks for the kernelly goodness.
It's the most likely cause, sprint has really been stepping up the rollout, in less than 2 months my lte coverage has practically tripled
could be eHRPD switching, I know deck got it all fixed up in the cm10 nightlies.....are you in a LTE area?
if not try setting mobile data to just CDMA and see if it sticks. I had that issue on the early cm10 builds where it would try and switch and just drop data completely.

My area in Jersey is on the short list for LTE activation in the short term, so there's a really good chance of this being the case.

My confusion comes from not having 1x coverage where I used to have it. Is that coverage dropped once LTE is activated? That would explain my issue.
I have read up on the eHRPD handoffs being an issue, but since I don't have LTE coverage at the moment I ignored that as a cause. I'll check out the newest Deck build and see if that helps anything.
Thanks for the help.
Ever since the 12B update I consistently drop off 4g , when I do have 4g I only get two to three bars, and wifi connection also is weak when connected. Speed tests on both 4g and wifi are significantly slower than Before 12b update. Anyone else having similar issues?
I called vzw, rep stated it sounded like a hardware issue, which I am not saying isnt a possibility but the odds of both wifi and 4g antenna failing simultaneously after the update seems far fetched.
Any idea on a fix? Is it possible to flash JUST a previous baseband/modem/radio (call it what you want) without touching the software version of the os?

I like Speedtest, but on the same device at the same location with no changes, I often get large variations in speeds only a few minutes apart. I'm not saying there isn't a problem (I haven't had a problem with mine on 12B), but results are hugely affected by the selected server and time of day. Try several servers to find the most consistent one in your area.
