Now... are you talking about ONLY the OTA update from 4.4 to 5.0? Or like autoprimes unicron

That would be the OTA update.

Will try this on wife's phone tonight. In running the Unicron build on mine... She won't let me "mess around" with hers, LOL

Let is know if this works.

The only issue I get is WiFi calling goes out at some times...disabling and reenabling WiFi does the trick

I'm new to the TMO G3, but I'm running stock, debloated ROM and can also confirm this works. Thanks for the tip!

Ive noticed a lot of people asking here and there about wifi calling. Ive gotta ask why is it such a needed feature? Is it for lack of service in some situations? Because i never use it and don't really see the point.

[Q] Turn of the 2.4GHz band for WIFI

Hi,
I have a really annoying issue and thats the missing option to turn of the 2.4GHz band. Corporate network usually broadcast all bands on the same SSID and I cant select whether I want to use the 2.4GHZ or 5GHZ band.
How can I go about changing this?
Heres a thread for the Samsung S3 that lost the same setting just to clarify what I need:
http://forum.xda-developers.com/gal...p-wifi-band-switcher-switch-2-4ghz-5-t1891970
I'm using a rooted stock rom.
And don't suggest changing the "router" setting since were not talking about routers here, were talking Cisco APS on large corporations where they are broadcasting on the same SSID. And I'm looking for a mod to the phone so I can turn of the 2.4GHz band to verify I only can use the 5GHz band.
I think this was present somewhere prior to the Lollipop update.
So please help, Its just amazing to see that noone have had this request before since this is a network setting applied to most large corporations and in areas where the 2.4GHz bands are clogged with signals you need to force 5GHz... I have seen the request for other platforms but not the LG G3.

Go select advanced settings and select WiFi frequency.

That doesn't exist. Due to that fact I'm in need of help =)

What about you change your ROM? I'm using 5.1.1 and it has that option.

There is an app called WiFi roaming fix in google play search and find it give it a try

I would lpve to use another rom but from what i read there isnt any that can make the camera work to its full potential.
But ill try that app tomorrow and see how it works once it detexts multiple AP's and multiple bands on the same SSID.

There were no settings in that app that prevents my phone from using 2.4GHz network. It was just basically saying how many APs there were on the current network and a setting to chose the one with best signal. 2.4GHz usually have better signal since that frequency penetrates material better then 5GHz and I want 5GHz only to try.

I am using Cyanogen ROM, and they have that option to select AUTO, 2.4 or 5.
STOCK ROM doesn't....=(

Thats exactly what I want. I would love to run Cyanogen but everyone says the camera cant deliver as LG stock. But you would think its not that hard to add the feature since its present everywhere except most stock ROMs. Seems like more manufacturers then LG removed the option when updates came to stock ROMs.

please help -No signal after reboot-

Hello, I bought yesterday an unlocked Htc M8, european version(i live in Europe) and after every reboot, after i enter the pin, i have to toggle the airplane mode on/off to get signal, after that it's all ok, no signal drops or anything, i also have a moto g and with the same SIM i have no problems, i thought the phone is locked or something, but thanks to some tips on an article from Android Authority the solution was to toggle the airplane mode, what could be the problem? i have no warranty and thought to ask here maybe someone has had this issue, thanks

solved, manual roam

I have the same issue how did you solve it?
Mine happened after flashing an AOSP Rom...

I have the same issue , it happened when I flashed an AOSP based Rom...
Each time I reboot there is no signal but after toggling airplane mode it works...
How did you reolve it?

Try this:
Manually Search for a Network:
From the home screen, tap the Applications icon.
Scroll to and tap Settings.
Tap Mobile data.
Tap Network operators.
Tap Search networks.
Wait whilst the handset searches for available networks.
Tap the required network.
The network has been manually selected.

It is not true if both bands share the same SSID... It is common at enterprises for example

I do not know what you mean. In: corporate networks or hotels it is more complicated as wifi APs may be centrally managed with roaming like: Mikrotik CAPsman.
But this if far beyond the scope of this topic.

I still do not get what is your problem. A50 scans both 2,4 and 5 GHz bands simultaneously for APs. You should see your GoPro generated SSID with no problem

I think I'm writing simple plain easy to interpretate English.
Wifi routers of some corporations spread their 5 Ghz and 2,4Ghz bands over the same SSID, and current Android versions don't let you pick the band in this cases. If you have a problem connecting to a 5Ghz band and you prefer the 2,4Ghz band instead, you have no means to do this since Android Lollipop.
I think this is the scope of the topic.
