[Q] Is there a method to improving the LTE signal reception? - Sprint LG G3

I recently got a Sprint LG G3 and since then my LTE coverage has been worse than it was with my Samsung S3. I have been having it drop to 3g very often and a mobile device is only as good as its signal! I am rooted with Xposed, Tweaks ,and app settings installed. I just installed the secret code app also but not sure what I can do to improve my signal. Thanks for any advice!

This is an issue with all the new Sprint Spark devices (Galaxy S5, LG G3 etc). It's because of a change in the way data and voice is handled. Once Sprint starts Voice over LTE on their towers, there won't be a handover from LTE to 3G towers so things will work better but when that will happen is up in the air. Just google "Sprint Spark LTE signal issues".

aside from ensuring you have the latest firmware which you should since there hasn't been an update since ship, there is nothing that can physically improve the performance of the hardware e.g. cellular radio without hacking/modifying the antenna itself or forcing the RIL to push more decibels which will likely cause more problems. Keep in mind Sprint may be doing repairs/upgrades in your city which may contribute to outages or drops in signal strength.

Ok thanks for the replies and hopefully it gets better soon cause I dropped my local cable/WiFi service due to price of services! I am going to get some kind of WiFi soon. Any suggestions on best service for just WiFi? One more thing u guess there's no way to force LTE to stay connected even at one bar? Thanks Again!

Before Sprint went dual band antennas with LTE/CDMA coming from the same location, you could change the network mode to LTE only like on the SGS3 but not anymore with Spark devices. At least not natively without root. Even with root it would require some hacking. As far as Wifi for home, i use comcast. If u just get internet with them it's not bad but if u bundle cable it can get pricey quick. Good luck!

[Q] No 4G. Please help.

I just got off the phone with a Verizon rep and they confirmed that there are no network outages in LA. So I guess there's something wrong with my phone. I'm currently running the debloated OTA rom with the radio that comes with it. I can intermittently connect to 4G, but only the upstream seems to work. It randomly cuts out, bumping my internet off or dropping me to 3G and 1X. Does anyone have any insight into this?

Well I think you were lied to,they have been messing with the network in several market over the last few days,if flashing different radios doesnt fix your problem it has to be the network, in sioux city iowa the same thing had been going on ask day, they are getting ready to switch the 4g on, it happened in three twin cities yesterday when they expanded the coverage, can't always believe what the reps tell you

The rep seemed like an honest dude, but I guess there could be sneaky network changes and upgrades. It might also be hardware damage. Does anyone about the 4G antennas on the back cover of the Thunderbolt? Does anyone know where I can get a replacement? A ticket has been opened for some techs to check out the network in my area. I'll keep you all updated.
You're sure your network mode is on CMDA / EvDo + LTE?
Positive. I can't think of anything else except network issues or hardware damage. :\
I am still in sioux city and the network is flippin out,give it a day befor you go buying hardware

Good call on that one. 4G is up and running when I leave the apartment. The strange thing is I have basically full 4G reception outside of the apartment, but inside: no 4G, but full 3G. Such is life, I guess.

losing data when data switches between LTE and 3G

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

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.

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
Sent from my HTC Rezound
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.

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...

Network Switching: Boost Signal or Disable 3g/4g?

All,
I have a battery drain problem that only occurs in locations where I have poor signal, particularly the office building I work in every other week.
I believe my phone is constantly switching from 3G to HSPA+ to 2G and back.
Is there any way to boost the signal so it doesn't need to switch?
Or should I try to find a way to disable 3G/4G when I am at this particular location?
Or maybe there is something I have not thought of...
Suggestions?
The only way to boost the signal is to buy their (AT&T) socall signal booster (mini tower) that cost you $300.00USD.

3G and HSPA+ don't really change much since HSPA+ is only used with high data transfers that require the multiple 3G connections.
Can you upload a screenshot of your battery graph, stats, and CPUspy?

Not the only option - Bidirectional amps don't have the numerous compatibility problems microcells have, however they're more difficult to install. At the workplace, they would have to be installed by facilities management - but corporate firewalls will probably prevent microcells from working anyway.
Also, microcells are notorious for murdering battery.

That is true, it is not the only option.
Unfortunately for me, I have the worst of both worlds, I live out in the country, so I have terrible internet and crappy cell coverage, so for users like me, its not really much of an option. I do know that I am a minority, but it still is frustrating.

A Wilson amp might be your solution then.
If network switching is something you still want to pursue, Try saving the following phone number to your contact list...
*#2263#
When you type it into the dialer, choose: GSM Band/GSM All. Menu/Back/Menu/End. Restarting the phone is not required. You can always switch it back by re-dialing the number and picking Automatic. Menu/End.
Verify the settings held by *#*#info#*#* Phone Information/Network Type. Should say: GPRS.
I live on the rural edge of 3/4G and the network switching was annoying and possibly not helping my battery life. I have 3/4G disabled most of the time because I don't have a data plan anyways (I use wifi for everything). Normal battery life with several hours of calls, wifi, email, browsing, etc. on the stock 2.3.4/HK7 is 2-3 days.

Signal Booster will help

Hi,
As mentioned by Entropy512, a signal booster may be a good solution for you.
Not only will it provide you with better signal but it will also help your phone save a lot of battery because it will only have to roam as far as the booster to get the signal source, compared to finding the closest cell tower.
For rural areas, if you are far from the cell tower, the installation of such a booster should be accompanied by an outdoors directional antenna pointed towards the cell tower and providing the highest signal gain inside your office.
Wilson boosters are among the most reliable ones, but you can also consider Cellphone-Mate or Wi-Ex, they may be a bit cheaper.
I used to have nasty 3G reception at my house and fixed it by getting a Wi-EX YX545 amp from the quantum-wireless website, they sell a bunch of boosters & antennas.
Hope this helps
If you just want to disable the connections rather than finding a way to boost the signal, try using Tasker. You can set it up so that when you reach your workplace, it will do what you want (disable data, enable airplane mode, etc). You can have the phone check for data periodically. As for voice calls, you can probably even set it to forward calls to your work phone.
As soon as you leave, the app will restore most of your settings (you probably would need to teach it how to stop forwarding calls).

how's T-mobile connection in Chicago Area?

Thinking about switching to T-mobile in the SW Suburbs of Chicago; I'm on wifi most of the time, so data speed isnt important to me, but, we MUST have good phone call quality in our house.
Is this an issue for anyone in chicago land, or, if we get a phone that is "wifi capable", and we have a fast,strong, wifi network in our house, does this become a non issue?
We had ATT, which was no problem in the house, and recently switched to Sprint, with the hopes of a stong "Spark Network" here; well, one of our phones in Spark compatible, and works fine, but the other 2 phones are HTC One's, not spark "compatible", and have poor phone call quality and reception in the house. We are waiting on an AirRave front Sprint, but, if that doesnt work, we're ready to go to T-Mobile..
Sorry for this weird question here, but, I trust my buds on XDA to give a real report on stuff like this, NOT the people from T-Mobile
Thanks! :good:

New to Verizon

Just picked up a new G3 and new service provider in Verizon. Is it common to be stuck on 3G majority of the time in a decent size city? It sometimes in a blue moon switches to 4GLTE, but won't stay long.
I am with tmobile currently as well as that is my main carrier, but needed good coverage in the bad areas of Pennsylvania. Have awesome coverage where I live with tmobile, however with Verizon not so much.
Is it common?
I guess I have 14 days to decide. Any feedback greatly appreciated,

take it back... verizon locks everything down tmo allows you to be free .
sorry i didn't actually help you in regards to your question.
The only time I see myself switch to 3g is where I have crappy service at my parent's place. Otherwise I don't have that issue..
However I'm also not in Pennsylvania so someone else may need to comment on that bit.
Perhaps they're doing tower upgrades over there?
The G3 gets really good reception, on par or better than the Motorola phones which are known to have excellent reception. I'd give it a day or so to settle along with a few restarts to see if you can grab an updated PRL. Outside of that Verizon may not be great in your area. I have to go outside to get a decent 4G signal, inside it's 3G most of the time.
That's the thing, I still have my T-Mobile phone. I actually live in Ohio, however work in PA and a little of West Virginia where I get no signal and can only make emergency calls. When in Ohio, where I live I get amazing 4G signal on lte. 40 down and 10 up to where on Verizon where I live I get 7 down and barely 1 up. It's crazy... Then again I am on 3G most of the time.
So wifi it goes....
Also is it normal to be on wifi and next to it the 4G/3G signal shows. I only have a gig of data is why I ask. Don't want unwanted charges on my bill.
T-Mobile g Flex unfortunately will still be my main phone. Unlimited everything.

I did this and at 1st it gave me full bars. I did a reset for some reason and when it came back it's back to 1 bar. Weird....So does this mean I'll stay on 4G and won't pan back to 3G, if so might need to be on global in order to get signal in bad areas.
Thanks though, see what happens.
Things to try:
Power off take out the sim, power back on without sim, power off and put sim back in.
Call Verizon and have then send an update to your sim card.
Factory reset your device
Get a new sim card

It's a new phone and I would have to already take put the SIM. I mean I will as I dont get why I am constantly on 3G. Thought Verizon was good at penetrating buildings for 4G.
Not to mention even when I am on 4G it's no where near the speeds my tmobile phone gets.
Might have to chalk it up to so many people on big red....I guess as long as I get signal in the boonies I'll be okay. Just a little disappointed.
Thanks for the help.
I had this same issue and switching it from Global to CDMA/LTE fixed it for me. I've read that it shouldn't matter if it's on Global.... But I clearly saw the difference.
This G3 gets the same or better reception that my S4 does. I'm happy with it

You should be on 4G, if it is available in your area. Signal strength is the main reason it'll drop to 3G, but that's only when your 4G signal drops above -100 dBm. Somewhere around the -115 is where mine decides it's better to switch to 3G. I even get some 1X's here at my desk, but I've got a crappy signal at my desk. If you're on 3G most of the time, then there's a problem. As stated earlier, take the following steps:
FDR (Factory Data Reset.) You'll lose everything, so back it up.
Go into the VZW store and tell them you want another SIM card. (Try not to handle it with your fingers and tell them not to handle it with theirs either.)
Replacement phone is the only other alternative.
If none of the above works, then you probably do need to switch back to T-Mobile. Just remember, you only have 14 days to figure this out!
Have you looked at a coverage map? Verizon does have excellent coverage but all carriers have holes

T-Mobile's version comes factory unlocked. It already has the TWRP recovery.
OTOH, T-Mobile's version is SIM locked and Verizon's isn't, so Verizon's version is more free if you ever need to travel internationally.
