New bell SGSIII drops signal all the time

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

Foot shouldn't affect cellular signal at all, all that rooting does is give superuser

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.

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

[Q] Horrible signal. My problem or Sprints?

So today I have had issues with connecting to Sprint's network. In a city near mine, they are upgrading to 4G. My phone has been going from full signal to zero signal within seconds. It is killing my battery life. I am running CM10.1 with the current nightly. I restored a previous version of CM to see if it was an issue with the ROM and I was getting the same results. Do I need to flash the radios or leave it be? Could it be because of Network Vision? Is there a way to back up my current radios in case something goes haywire?

Its most likely a carrier issue....make sure you have the most current radios installed which are FD02 if i remember correctly....other than that its a very rare occurance that software would affect your signal...probably due to the work that they are doing in the area....turn off LTE and see if the 3G signal does the same thing...good luck let us know what happens

Its sprints terrible network.

I've turned off 4g, reconnected with airplane mode, restarted my phone, fixed permissions. 3G is the same. I hardly have any service. The thing is, the past couple weeks the service here has been awesome. Then yesterday, this.

Like i said its most likely the work that they are doing .... Give it a couple days because the same thing happened to me when Verizon was putting up their towers near me when i had my thunderbolt....give sprint a call see whats going on
...check their website see what it says for your area....for what its worth I'm 99% sure its their doing

Well, I have confirmed it to be on Sprint's end. All it took was a quick drive around town to pick up a different tower. My buddy has a signal booster in his apartment and I was picking up full bars there. Here's hoping LTE is close!

Phone wont connect to 3g when set to CDMA\LTE\EVDO mode

I have an interesting issue. My wife and I both have Note II's. I have a grey one, she has a white one. Both are on the latest Stock Rom and rooted, same kernel and modem revisions. Both phones on the dreaded 2000 PRL (Havent got around to flashing another one because we have an Airave 2.5)
My phone will not connect to 3g at all when I have LTE enabled. The other phone connects to 3G just fine with LTE enabled.
I have another friend that only sporadically connects to 3g with LTE enabled. If I set the phones that wont stay connected to 3G to CDMA mode everything is fine.
Any ideas?

Try automatic?

Does this happen around the airave? Airaves are known to cause a host of isues with rooted phones even with no custom roms

The only way to get 3g when lte is enabled is when you lose lte sinal is you just want to use 3g set it to cdam mode only if you set it to lte

Cdma only or global
I was reading some other sites and threads after I encountered a problem almost just like this because I had switched my signal type while on AOSP.
I discovered that because our phone are global they have different connection setting and in short when you switch to either global mode or CDMA only, and try to go back to lte evdo the phone will roam constantly and will not be able to reconnect to lte. So while I was trying to fix my LTE I managed to force my LTE on but I wasnt getting any cdma or evdo. finally I got everything back to normal by flashing a back to stock rom and doing a hands free activation.

I'm also have an overwhelming time with 3g. I have no lte in my area but have tried both CDMA only and CDMA/let settings. My 3g is on and off within 1 minute intervals or hours at a time. I pretty much have no data connection 95% of the day, until I get home from work and can hit WiFi.
I'm just stock rooted on MC2 and also on prl 2000.
I've been on the phone with sprint for days trying to figure this out or get them to waive my ETF. I refuse to keep paying for service when I am not getting any. It's bad enough they don't have 4G much less LTE here, but I can't continue to do these sub par dialup speeds to no speeds.
Any other tips to try would be greatly appreciated. As sprint says everything is fine in my area...
Go figure.

Yeah, same problem here. Somehow after rooting the phone i completely lost 4G LTE connectivity. Now everywhere i go it's only on 3G or EvDo Rev-8 which sucks. I think the only way of fixing toys issue is to Unroot and go back to stock ROM.
After doing a lot of research on the matter that is the only solution right now to our 4G LTE catastrophe. :thumbdown:

[Q] losing data connection

I regularly lose data on my G3.
The 4G LTE icon is still there, but i would only get upload arrow blinking, giving me no access to internet.
if I reset the phone i get my data back, or i could just go in and out of the airplane mode.
any thoughts on this ?
both me and wife's phone has this problem, as well as 2 of my friend's.

From an earlier thread...
http://www.tmonews.com/2014/07/t-mobile-lte-network-stalling-or-dropping-out-youre-not-alone/

This happens on my m8 as well. Its a network issue.

discussed here as well. http://forum.xda-developers.com/tmobile-lg-g3/help/intermittent-data-drops-t2825961

I don't know it's whether handset or network, but the situation isn't much annoying as it used to be with Note 3 in NYC.
With Note 3, I have to toggle few times a day, but with G3, I don't remember how many times doing this.

I can confirm the same thing with both my white G3 and my wife's white G3, they both just lose data connection with no traffic being sent or received, despite having a -59dbm for our signal at home!
I confirmed on both devices that no data was being sent with the Internet Speed Meter Lite, showing no traffic on the data connection, but active LTE connections on both.
As mentioned by others, pushing them into Airplane Mode and then back gets the data flowing again, but it does stop again later in the day. But they both don't lost connection at the same time (though it has happened several times of both at the same time), one will have an active connection while the other would not.
This seems to be a handshake issue, whether the handshake is expiring or is not accepting possibly.
It's also happens throughout NYC with us, at home, midtown Manhattan, Queens, etc with no known symptoms to cause it or time issues, such as every hour or so, or amount of traffic. Whether constant streaming or just idling, the data connection just dies out.

Happens on my note 2 as well, it's T-Mobile. It will be a while until their network is stable. Last year I went through 6 month of 2G speed on a 4G network because they are upgrading to lte

Thanks for that info, I just came over to T-Mobile after 10yrs with Sprint just last week, so this is my first experience with LTE on T-Mo, so I wasn't sure if it was the G3 or T-Mo.
But, I have other co-workers who have had LTE on their T-Mo phones since this time last year. The fact that T-Mo might still be having problems with their LTE service for this long should be something fixed already. Unless they're getting around to it with their Wideband LTE upgrades.

(Q) LTE

Is anyone experiencing LTE problems? I have great Spark signal in my area, but this phone seems to go to 3g all the time. My other phones are always on LTE, so obviously coverage is not the issue here. I will unroot thru Odin and see if it's a root problem.

Not a root problem. Weird part is it only seems to happen to me in areas where there is really strong 4g, like in my house. At work, I am on a weaker 4g signal all day long without issues.

Try updating your profile and prl. Also make sure you have CDMA/LTE selected under mobile network.

I have the same problem. It keeps dropping my signal to 3g..even when it's on 3g sometimes it loses the 3g signal and reconnects to 3g.. the areas I go always have band 41 ...my previous phone was the nexus 5 and the signal was great...never drops connection like this...I thought it was only my phone as I haven't seen someone with the same problem in the forums. I'm in nyc area

Hopefully there is fix soon, it's very annoying to have this data issues.

Its not just your phone mine does the same thing at my work. I switch between multiple different band 25 26 and 41 towers as well as 3G towers. It occurs while the phone just sits on my desk. Theres a couple other threads discussing this. To my knowledge no one has any usable suggestions to help with this.

My Note 4 does the exact same thing. I'm in a fully covered spark area, my old s4 always connected to lte with about 10 meg download. Awesome data offensive note 4 gets 3 to 5 meg download.. sometimes only getting 0.01 upload speed. That's the only thing that consistently bothers me about this phone. Oh yea it also constantly drops lte... to 3g. Feels like it's data is going through a dial up modem. I'm going to check the Sprint forums and see if I can find any good info.

Happened once in one place i was. Lower LTE signal and the phone kept dropping it and falling back to 3g, while my gf Lg G2 kept the LTE connection. I'm thinking they need to tweak the radio software in a future update.

I've noticed that all the TriBand devices (Anything with Spark) switch to 3G for a bit then connect back to LTE/Spark. I haven't heard anything from work about this issue yet. I've also noticed its areas that have low Spark signal and high LTE signal.

My guess is it's a handoff problem. I will see all bars but LTE grayed out while riding the metro.

There is another thread touching on this too....I am having terrible LTE connection. My wife, who is an iPhone 6 user, gets 4 bars (or circles? lol) of LTE while I can sit next to her with 0-1 bars LTE or 3 bars 3G. I love this phone too much to complain alot about this but I am confident Sprint/Samsung will release an update to fix this.

The exact same problem occurred when the LG G2 got the spark update. It took 8 months for sprint to issues update that was specific to the LTE problem. I had to factory wipe before and after the update to get it to stick. The only difference is before the G2 was updated a toggle to airplane mode would bring the LTE back. That trick does not work on this phone. I will also add I drive alot at my job 6 hours plus a day. I go to the same spots to do paperwork in my truck. My Note 4 will not stay on LTE/Spark in locations where my G2 had a constant 10-15mbps connection.
