Upgraded to G3 and lost LTE @ home!! - Sprint LG G3

So, I upgraded from the EVO 4G LTE today...
Now at home I can only get 3G instead of LTE!
I could get LTE on the EVO 4G LTE here before, now it's just 3G!
I do get better bars, though.
I have updated the profile and PRL
Is Sprint Spark running off different towers than regular LTE or something? That is the only thing I can think of that would do this.
Any ideas? I know LTE works near Sprint HQ.
Kind of bites, as now I will have to rely on wireless due to Sprint's abysmal 3G network...
Let me know if you have any ideas.

Try settings, network tab, more, mobile networks, network mode. Change it from global to lte/cdma. It seemed to work for me. Same issue.

Yep works. I did it and drove around a bit and it picked up Sprint Spark LTE. When I got back home, it is now on LTE with half bars (30 Mbps - 45 Mbps_ so I am happy :good:
[edit]
Curiously, this has come back. LTE tries to connect, but then drops to 3G.
Wondering if it's possibly just a tower issue by my home.

It could possibly be because the Evo LTE has 2 radios, while the spark devices only have 1. I've noticed that if I lose connection for any short amount of time, it drops to 3G and stays there for a long time.

I've found that if I
1) Place LG G3 next to window
2 Restart the phone
It jumps to LTE Spark. Otherwise, it defaults to 3G.
I get strong 3G and weak LTE inside, so I imagine the phone thinks I want the stronger connection over the faster one

Do you have connections optimizer turned off?

Yes, I had to turn that off immediately because it kept pushing me back on Wireless automatically.
I reproduced this problem elsewhere in my city, where - after a reboot - the phone jumped to LTE Spark.

Have you tried toggling airplane mode when this happens? To get the radios to reset? Works on my S5. If I drive through a particular part of town my device drops to 3G and won't jump back to 4G without either e reboot or a data radio reset. I've heard the problem has something to do with certain towers needing updates.

That - and the power off/on trick - both work about half the time.
I'm not sure why it is so inconsistent

I use LTE Discovery to reset data sometimes to get LTE connection. Much better solution than a reboot. Plus many other benefits on the app.

That's awesome; I didn't know about that program.

Welcome sir, because I'm a nerd, I have that program alert when I'm under spark band

This is what worked for me...but it resets your phone.
In your Sprint dialer, dial: ##72786#
That should reset your phone completely and give you consistent 4g lte. I had the same problem and thought i was going to have to return the g3, but fortunately that method of resetting fixed my problem. Just to note, hard resetting through the settings menu does not work the same for this situation.

Old thread i know, but this has something to do with the signal threshold. I have been dealing with it for years. Basically if i understand it correctly it will drop to 3g when 4g hots a certain signal threshold. I have found though that even with full 3g signal it is still increddibly slow compared to barely any 4g signal as far as data is concerned. The phone just thinks you are better off with the stronger 3g signal. It is good to hear i am not the only one who thi ks Sprints 3g is pitiful. I cannot load anything with it.....most webpages and apps give up before they load from 3g. I use Intelli3g to force my phone to stay on 4g because I have found that even the weakest 4g is better than my best 3g signal. Although using Intelli3g takes a bit of modding to your phone.... On the LG G3 ls990 it requires root...which is easy....but also twrp manager installed ...then you have to flash Xposed framework.....can be a bit scary but possible. This is the only way I know of to force your phone to stay connected to any signal 4g 3g 2g ect....just select fast network and slow network and flick the switch. This was a must app for me because where i am....signal is the worst. Screenshot of the app I use...
