connectivity issues - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

The phone keeps switching often between 3G and WIFI both icon comes on at the same time. I have done nothing different since the MK2 update came out. low reception and bouncing in and out.

Sounds like you have the automatic switcher on. Since you have low signal your phone wants to hop on WiFi.

This is the first time that I noticed it doing it. Is there a way to change the setting so it stops doing it?

Settings/WiFi/hit menu then select advanced/ uncheck "auto network switch"

I'll give it a try. Would it connect automatically to 3/4g when I leave the wifi area? Thanks.

Yes it will still do that. I always have it unchecked and it switches to 3G when I leave my apt.

Can't use internet and call at the same time?

Any reason I am unable to do this? As soon as I pick the phone up I lose my internet, hotspot etc..
Anyone know why? Its a right pain

What are you using - 2G or 3G?
Because if you are using 2G it is normal to disconect the internet when you are receiving a call.
Set to 3G only and try again. Only in 3G it is possible ro have at the same time call and internet data receiving.
Regards.

I think it depends on the carrier too. Not every carrier supports this (if I'm correct)
I'm on HSDPA so it's fast enough to cope.
How do I set it to use 3G only?

Settings > Wireless and Networks > Mobile Network Settings > Network Mode > 3G only
You cannot use ANY DATA while on a call, it has always been this way.

2G(EDGE) disconnects while on call but 3G always remains for me while even on call.
I've used this feature before by switching on the speaker to quickly Google something. I was on an H/3G connection at the time and I didn't have a problem. I can also use glimpse while on a call, but that can heat up the phone a bit.

Not true, there have been many times that I have been on the phone and quickly browsed the internet at the same time on 3G, both on my blackberry bold and my desire hd. Best option is to reset your phone if you are sure you're on HSPDA

Network band selection menu is removed from the AT&T rom. It has always been absent. They are forcing everyone to use their lte network and not the slower network.
Its been discoused several times in the forums search is your friend....

Yes.... Ive been using this for years....
And if you WANT to make it stick download Net monitor from the market place and click menu and go through the service menu turn RAT supporting off/on or whatever then choose go through and find what you want to set it up if you want it TO STICK. BUT I have HAD a TON of issues in the long run by changing those settings on a ton of different phones and I always end up with an issue with Service of some kind later down the road. So I just use the code I menched above as it resets when phone is restarted.

From what I understand about doing it this way, you will be stuck in that band only. So if you are ever in a low coverage area such as Edge, you will have no signal. Its not WCDMA + auto. Its ONLY WCDMA.

Choose WCDMA prefered to get everything except LTE.

hey there I tried the code you provided above and set the network mode to wcdma preferred, but still i can see the lte symbol near the battery icon at the top.. does it mean i'm still getting the lte network?
After selecting WCDMA mode, my phone's network was completely lost. But, If I switch in GSM mode then my phones network works again smoothly on GSM network. But in my area the network operator's network that I'm using is too good for WCDMA network on others phone..
Someone please help me to use WCDMA mode on my Samsung SGH-I337 in my religion

[Q] Shortcut to toggle 2G? [SOLVED]

I'm currently using PA and looking for an easy way to toggle "Use 2G only" when I connect to a wireless network. I've tried tasker and llama, but they change the network mode when toggling back. I'm configured for 4G, so switching back to WCDMA doesn't help me much.
Thanks in advance.

What do you you mean with they changed the network mode when toggling back?

Tasker and llama have an option to toggle 2G/3G or wimax. When it executes the command to switch to 2G, it checks the box and switches network type to GSM. When you toggle it again, it unchecks the box but also switches back to WCDMA which is the default network type. I need the network type to stay LTE/GSM.

I don't use Paranoid Android but I'm pretty sure it has Quick Settings customization. You just go into Quick Settings menu and enable "Network modes". The older CyanogenMod power widgets have that toggle too.

It means it switched from LTE to HSPA.

PA has the same network modes that you listed, but LTE isn't one of the options.

LTE option only show up if you flash the LTE package that install LTE baseband and edit the build.prop to enable it. It's a separate toggle dedicated to turning on and off LTE only.

I have LTE auto-enabled. My issue, is getting an auto-toggle between 2G and LTE.
I don't know if you have downloaded and used power toggles. I use the power toggles widget and quite easily toggle 3g & 2g. Hope this helps.
Sent from my Nexus 4 using xda app-developers app
There is no CyanogenMod toggle to allow you to get directly between LTE and 2G, you have to first disable LTE, it will automatically go to HSPA after that, then you have to press the 2G/3G toggle to change it to 2G manually. I do not know of any other ways. In *#*#4636#*#*, you can select LTE/GSM, but I doubt it will work for your purpose either.
Thanks for some of the replies, but I'm NOT trying to change the network mode. My network mode is currently set to LTE/GSM and if I check the "use 2g only" (see screen shot) then the network mode switches to GSM only and back to LTE/GSM when unchecked. Any of the toggles listed by others above change the network mode and have no method to change the network mode to LTE/GSM.

I was able to do this with Tasker. I didn't realize that by default, Tasker will restore settings to their previous state when they exit the profile. Previously, I was trying to use a second profile to set the network mode back, and this is where I ran into problems. I also set up a second profile (along with the Secure Settings plugin) to enable/disable GPS when going between Wi-Fi.
Now, to just configure it to NOT switch the network mode while on a call.. I think there's an IF statement for that.
You can use secure settings with tasker to force lte also. That's what I do.

Good to know! Thanks
This won't be very helpful, but I found out AOKP have a specific 2G toggle, I would guess this means PAC rom should have it to. You can toggle between LTE and 2G, but switching it to LTE really means 'lte/wcdma/gsm'.

@eksasol Thanks, but I primarily use PA.
@frigidazzi I tried switching to LTE with secure settings, but it changed my network mode to GSM/CDMA. Can you get it to switch to LTE/GSM?
Yes. Mine goes to lte/gsm auto prl. I'm on radio .33. Using aokp 4.2.2 with newest Franco kernel. I'm not sure which is the trick to get it to work. I've never had a problem with it.

In my network, the operator can set the policy to force the user to use 2G or 3G network first.
By default it is 3g h+ when I turn on my data plan. I only see edge after recovering from a signal loss
