LTE/CDMA in ro.radio.networkmode screws up phone.

Hi, guys I recently ran into an issue with the build prop modification in regards to network selection. If I enable the network selection as pointed out in one of the other threads and select LTE /CDMA my phone will lock on LTE however no phone calls can be made out or recieved. I had to reflash to 10k then reroot and then change the build prop to CA/TLS and finally hardreset via stock recovery. Anybody else have this issue?
UPDATE... looks like as long as i dont try to make a call the option to switch it back to auto is still there. One a call is attempted and fails the option to set to auto disappears.

Most carriers Phone calls and Texts dont go through LTE...... If your setting it to LTE only thats why.

I understand but after it's been on LTE for a while it doesn't give you the option to switch back.

Depending on what rom your using under mobile networks there is network selections with
LTE/WCDMA/GSM
GSM Only
WCDMA Only
and LTE only

Right, thats what normally the options are however after about 5 min after selecting LTE/CDMA the only options that appear were.
LTE/CDMA
CDMA
thats it.

How are you changing it? Changing it via Build.Prop? Then there is your problem, JUST change it using the setting under mobile networks..

I'm changing it under mobile networks.

Stop changing it to lte/cdma and you're phone will no longer mess up. Leave it on gsm/wcdma/lte auto. You're phone will switch when the appropriate network is available!!!

Simple fix. Just select airplane mode for a few and then toggle it off and you'll see your network options come back once data roaming turns off and your carrier logo appears. I typically run lte/CDMA to get consistent lte speed bit when a callsade I have the same issue as you. But I just gave your the fix so your good

Thanks a lot captain obvious, the point of the thread wasn't to "not switch it" dude, it's finding a work around and make everybody aware of what happens.

3g 4g issues

I have an unlocked sprint g2. I moved to Oman a month ago. Now gsm services work fine but 4g and 3g doesnt work on my phone. Can anyone explain a possible solution to this? Do i need to flash a baseband? Will this issue be corrected if i root and flash a custom rom? Thanks in advance guys. Appreciate your help.

first make sure the 4g and 3g bands of your current provider are supported on this phone. If they are, then there is a rom which might help you get 4g or 3g but i dont remember the name of it (terrible i know) 3g could have to do with the apn settings as well...

Hey thabjs for the reply. I know about the 3g settings, even i thought about the apn settings. But then there are no options to change apn settings in this rom. Perhaps if i change the rom i will be able to change fiddle around with the apn settings?

[Q] ATT signal troubles on H815 US

I purchased my phone (h815 US model) online from swappa and I love the feel and look of the phone, Love the camera, BUT my phone wants to stay on hspa all the time. Where i had 3 or 4 bars on my s5 active I get HSPA unless I go in to settings and sellect ATT:LTE from network operators which only last until my phone goes to sleep then im back on hspa. Anyone else experiencing this? Or anything i should try? Thanks in advance for any help!

Maybe with hidden menu access via dialer,you can permanently enabled it...I don't know the actual code that might work for your device..but you can find it through here..In general threads maybe

I had to set the proper APNs on my H815, additionally I had to tell it to use GSM/WCDMA/LTE Auto under Network Mode in the Mobile Networks settings.
AT&T APN settings

After that, it's been using LTE where available.

Thank you @Daptonic . I was attempting to use the "ATT nxtgenphone" APN because it works better on ATT devices but I guess the ATT Phone APN is needed for non ATT devices. Rebooted phone and it went straight to 4g. Thanks for responding.
Edit: dammit, it went back to hspa again......

Data connection switch 2G/3G/4G missing

Hello guys.
I need another tip as I am not running AT&T network in Europe I wanted to ask you if you are able to switch manually between network types 2G/3G/4G. The phone connects me to 4G regardless to how bad the reception is, and in that areas I want to be able to swotch from 4G to 3G.
Does any of you have a solution for this item?
Your responses will be appreciated.

As far as I've ever known, the only way to really impact that without root would be to change APN settings. I can't really provide specifics on this device, but there definitely isn't a quick and easy way to toggle between them.

You saved me from selling my beloved S7 Active! After searching (camo green, unlocked) from about 2 months, I bought it a week ago. I'm using "MINT SIM". So on default network settings, I'm fine outdoor, but indoor situation is horrible, it keeps me in LTE (barely 1 bar). So calls were getting disconnected. I don't care about data in my house, as I'm on WIFI all the time. Now, from your provided code, I selected 'Global Auto' and I'm getting ALL bars of network! It is connecting me to UMTS automatically! Data speed good enough for me! I don't have to sell it anymore! Thanks a lot!!
