Some basic info: Sprint SGS3; rooted, manually updated to LG8. Otherwise, stock.
Since then, I've noticed that my phone doesn't "hold on" to 4G as well as it did pre root and update. For example, the 4G icon will be next to the signal strength in my status bar then it will disappear, there will just be signal strength with no connection indicator then either 3G or 4G will appear. I don't ever remember this happening before root/update. I haven't flashed anything else on the phone, and the main reason I rooted in the first place was so I could easily tether.
Has anyone else had this same issue?
Its funny that the LG8 update was supposed to help users that were having LTE connectivity issues... this happens to me on occasion too. i would venture to say that a combination of LTE still being in early development and coverage being spotty at times even in areas where u may have gotten full coverage at one point plus the "Connection Optimizer" that often jacks with ur data connection switching between wifi, 3g and 4g(LTE)... try doing a ##72786# to reactivate ur phone on the network... this will automatically re-associate ur data profile with the network and update prl info as well...
+1 I have the same issue

Thanks for the reply. I'll try the ##72786# and report back with results.
You make a fair point about LTE still getting off the ground, but I will say that pre-root/update, my phone held 4G consistently. Whatever the issue is, hopefully it will sort itself out soon, or enough people will have the same issue that it spurs some action on Sprint's side.
I'm in Houston, FWIW.
Edit/Update: ##72786# seemed to do the trick. HOWEVER, about 15 minutes ago, I attempted to turn on WiFi Tether. My laptop connected with no issues, but about 5 minutes into it, neither the 4G nor the 3G icons appeared next to the signal strength meter. ##72786#'d again, just to see if it made a difference, updated PRL and Profile. Things are holding steady so far, but we'll see how long this lasts.
I'll try to update later in the day.

Glad to see it worked. This is by no means a permanent fix. As u flash different roms thru out ur phones life span its a good idea to run this code every so often as flashing can overtime degrade baseband performance as those files dont get replaced with a rom but different roms interact with those files depending on the tweaks made at software level...

I can't wait either. For those that have 4G i'm curious as to what the battery life is like and how much faster the network is on the SG3.

I am up here in Sugar Hill. Sprint Map shows you deep in LTEville. I worked in Tucker last year when a co-worker got a Verizon Tunderbolt. His 4G was screaming. He was getting 40+ down!
But the map also shows Cumming in LTE land so I drove over there just to see what LTE looked like and I saw the icon flicker on for about 30 sec. but it never really was there.

Just flashed back to LG2, so I'll update later and see how things are going.
Just got the phone today and rooted it right away In the last 7 hours its dropped about 7 times. Im not sure if its because of root or what. I have not installed any other rom.
Its not the root... Its the carrier

Could it be because im inside and its trying to switch between H+ and LTE all the time? Is there a toggle i can just keep it at H+?
I would find that unlikely but you can try being on HSPA only and see what happens

You can go to settings, more, mobile networks and switch from gsm/lte or just gsm. But I have not dropped data other than H to 3G every once and a while in weird areas but not a whole lot, but talk to bell online chat and see what they say.
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2
what do you mean it loses signals?
does it get disconnected to the network completely? and you get the emergency calls only message?
because that happens to me as well. I am also thinking its because the phone tries to switch from LTE to H+ over and over.
I think I'm getting the same problem, a fee times a day i get zero signal, then all of a sudden it pops to full signal, without moving the phone. When i lost the signal, it says emergency calls only...

I had the same issue downtown Ottawa. I switched to HSPA+ only and the problem went away. Turned out, Bell was working on their LTE stuff and that was going up and down and so did the phone. Now, it is all good.
Try having Bell reset your connection from their system....then get them to give you a different SIM card.
I had the exact same thing happen to me when I was in a zone not completly covered by LTE, whenever my phone lost LTE connection I would lose all signal for a bit to eventually drop back to HSPA+, I simply disabled LTE until the coverage reaches where I am completly.
Yep, disabled LTE for now. Problem has gone away and battery life fixed
me and my brother have had the issue in dowtown ottawa on rogers. seems fine in my apt in the market but on a patio and at a restaurant it just wouldnt work!! couldnt send texts, or receive, couldnt call, sometimes it showed i had full bars and lte but couldnt do anything. my brother complained about this the day before. i will try disabling lte next time

When I first installed CM10 on my S3 I was having wonky 4G connections. I eventually figured out how to get LTE to stick by switching bearer off LTE, saving, going back in and changing it back to LTE. It worked for me and by the time the dailies arrived I rarely had to touch it.
Today I flashed 10/02 and noticed massive battery drain. I was also getting 4g showing with grey bars, not blue. So I rebooted and began to recharge.
Now I can't get 4g at all. I've messed around with the APN settings over and over without any luck. I just switch back and forth from 3G/H+
I checked my IEMI, Its there as usual.
I tried forcing just LTE through the dialer and just get grey bars (full) without any data connection.
Any ideas? Could my phone be just a dud and the best solution is to revert to stock and return?
Thanks!

Make sure data is enabled in the settings
data is enabled. I can get 3g/h+.
I also tried loading my last two nandroids. No luch there either.
I have the same problem as you, LTE just suddenly stopped working today, tried everything to get it back but no luck. On Paranandroid..would reflashing the modem/radio help at all?
possibly weak LTE area? seems to always be my problem... i'm on slim rom and can get lte if in the neighbourhood .. lol

Sometimes things like this make me doubt my reason for sticking with Rogers is reliability. Not just LTE today, there's also suppose to be a problem with RogersOne users in Ontario not being able to make or get calls seems to be fixed now. Had LTE for about 30 secs a minute ago and 4g is still really splotchy and keeps disconnecting.

Do you guys have any issues with signal on your GN2? My GN2 will just drop all signal and show a circle with a slash in it as if there is no signal at all. At first I thought it was my airave but it happens when I am not within range of my airrave as well.
I also have issues getting the phone connect to my Airave 2.5. Anyone have any ides about this?
I just noticed that I will have full signal and while trying to send a text, the text will look like it's sending but the signal will drop. I have to wait for the signal to come back and re-send the text. 5 minutes later and the same thing happens.
I had a problem like this also, I reset my Airave and then updated profile and it worked. Maybe give that a try.

Yeah I've tried this. I reset my Airave and the GN2 will connect but at times it just disconnects.
I still have the problem where I'll turn on my phone and there will be no signal and it will connect to the sprint network after a minute. This happens with or without the airave.
I just flashed the phone back to stock and still having the same problems.
Did you update your profile after resetting the airave? Just a thought?

Nope. I just set it to home only for the roaming mode instead of automatic and I unchecked the domestic roaming guards. I still get signal drops.
I think (not 100% sure) that the signal drops when the phone is idle and not when its downloading something or even when I'm on a call. Not sure if that helps.
After you set it to sprint only did you unplug the airave for a minute or so, then plug back in? Just a suggestion. I was constantly roaming when I would first come home and it would not connect to the airave. I stopped having the problem after I switched to sprint only. I hope you figure it out.
Sent from my SPH-L900 using xda premium
Same deal here. We ended up calling sprint and they sent out a 2.5 unit which has been more reliable, if not perfect. If we run into this with the new unit a quick switch to airplane mode and back again usually fixes it and if not then a phone reboot does. While your way this not the most reliable I think it's definitely have something to do with the note. Be sure to call Sprint so they are more likely to address it.

No I did not but that's only because I was not near the airave when I changed the sprint only setting. My connection drops outside the range of the airave too.
I took my phone to a corporate Sprint store and the tech told me that due to the towers in my area being down (due to the hurricane) that's why my signal drops. But I don't buy that...my signal was fine on Friday with my Galaxy S3. My signal drops at work a lot and my co-worker with his Sprint Galaxy S3 does not have the same signal problems.

I have an Airave 2.5. Sorry, I should add that to the OP.
Here's an update. I called sprint and told t change support about the problem. They ran through the usual steps like update profile, prl, and a factory reset. They made sure the provisioning was okay on their end and it was. Since I have TEP, they decided to ship me a new or refurbished Note 2. Let's see how that one goes.

How did it go?
I think I am on the same boat. I have a brand new airave 2.5+. My GN2 only connected to it twice, after lengthy updating PRL, profile, etc. I can't make it connect normally. Wife's iphone 4s connect OK. I was told because a tower (not very strong signal) is preferred, my phone doesn't connect to airave. I think it is a bug but don't find a solution. I search this forum and found people have similar issue for GN3. I tried PRL 51097 but no luck. BTW, I am on PRL 2011 now.
Can someone post PRL 2011? I made some progress on PRL 55016 but my phone has 2011. I don't know how to read it out, nor do I have the MSL.
---------- Post added at 11:19 AM ---------- Previous post was at 10:22 AM ----------
Does anyone understand why on earth my phone reconnect to cell tower right after I hang up a call? The phone was connected to airave before and during the call (according to the signal strength, unless I was fooled).
It wasn't prl. It was my Note 2. At the time Sprint sent me a new Note 2 and it worked fine.
At first I thought it might have been my rom, but it seems it's happening with my GF's note 2 also.
Coverage we used to receive in some areas is almost completely gone. It will show signal and the 4g symbol but basically have NO internet service whatsoever.
On a better note, we've been receiving coverage in some areas we don't usually have it.
I'm hoping this is just a temporary thing due to the attempts to upgrade towers for LTE.
I don't know if it's because of the UVBMB4 update, but t-mobile service has been pretty crappy lately. Period.
We're in the San Gabriel Valley area.

I believe my service has suffered as well. Before the last update that enabled our Lte radios, I had great speeds, now it's slowed Way down. I'm in San Diego CA. Hope that it's just as the Op said, LTE towers being updated and what not.

Definitely have noticed a deterioration of service over the past month here in NYC.
Its because for some reason that new LTE APN is slow on HSPA+.. unless you have LTE in your area switch to the EPC APN. You can find the settings online. Its litter ally consistently a difference of 6+ mbps I have extensively speed tested lol..... click thanks if this helped

Same here, I thought it was rom related.
YES! My service has sucked royally for the past month or so. Data latency/hangups/slowness, and the signal will just completely go away sometimes. I noticed that it started as soon as I flashed the most recent radio too, I'm about to go back to the old one.
Count me in, even my regular phone reception went from 4 bars no 1 or 0!
Can anyone point to towards old radio to flash? I go from no signal downstairs to full bars upstairs...theres an obv issue with new radio.
Yup I've noticed this beginning this week I've made zero changes to the phone. I used to get full bars at work and this week it bounces between full and 1 bar regularly. Theure messing with towers for sure

I was getting about 9/0.6 and with flashing back Im getting... 14/2 Though Ive been on HSDPA 15 & 21. Though Im not getting 4G as much, but it was sporadic anyways and I lost signal...and now I am not. So, Im happy now even though I am on 3G. However... in my corner big red has same problems as they wanted to not have tons of towers in this corner and theres only a ATT Tower....for a decent distance. basically reception fringe. though I am a new subscriber so i haven't experienced normal TMO, I literally got my device yesterday around 6pmish but it def wasn't normal and flashing previous radio did fix it like it solved everyone elses issue

my problems started last friday. i have limited to no service at all; no data, no voice, even no signal at times (circle with line through it, not just no bars). when i do get a signal, the phone refuses to register on the network. when im at home, i have intermittent service. i miss calls, texts wont send, if i do get a working call, it drops after a bit. there are times when it works fine, even on LTE but it never last long. went to the tmo store last night and they gave me a new sim which didnt do squat. already done the factory reset option (twice). phone has never been rooted, all stock. im in the KC metro so not like in the middle of nowhere. they said my next step is a warranty replacement phone if the sim didnt help. not sure if my problem is at all related to everyone elses in this thread, but yeah, service has sucked.
One of the issues, especially if you switch from 4g to edge to gprs a lot, is a setting in the new modem.
It's something called acquisition order. It has 3 settings:automatic, gsm_umts, umts_gsm. In short it tells the phone what kind of network to prefer. It will search for and use that type of network first.
Prior to the latest update it was set to auto. Now it is set to prefer umts. For some reason this has caused an issue I've come to call phantom 4g. Where it'll say 4g with no bars and no data service.
That is my guess. I'll look into it further.

Thanks guys for the heads up on switching to an older radio, I dont have LTE in Miami yet and was having slow internet for the last 3 weeks, I just switched and wow! What a difference. I'm also using the Epic APN.
I also noticed that speeds were degraded after the update. However, there is a simply fix to make your web a tad bit faster....
Go into your network settings, and switch your mobile network from LTE/4g/3g/2g to just 4G/3g/2g
your device will stop looking for an LTE connection and will just utilize HSPA+
Made a world of a difference on my own device. Connecting to the play store, opening web pages, everything was right back to where it was before the update.
Obviously if you live in an LTE area, there is no need to do this...
