[Q] Network problem - Galaxy S 4 Mini Q&A, Help & Troubleshooting

On my s4 mini lte, each time I turn on mobile data it doesn't work, doesn't matter if I have 4g or not (in the notification bar it actually says '4G'). When I go into settings and turn off lte (wcdma only), my Internet does work. Is there a problem with my lte antenna?

Distinguishing between 3G and 2G connectivity

I am using a flashed Epic 4G on the Page Plus network. Whenever I have a data connection, the 3G icon appears on my phone. Does this 3G icon refer to true 3G (i.e. EVDO), or does it include 2G speeds (i.e. 1xRTT) as well?
Are there any indicators out there that can distinguish between 2G and 3G data connectivity?
On the stock framework for Epic they use the 3G icon for 1x and 3G connections. Many custom ROMs/themes have a proper 1x icon in them. Also, you can download Network Info II from the market and it'll show what mode you are in under "Net Type:" about halfway down the screen.

How to Powersave through 3g

I was wondering how one switches from 4g to 3g(which i think people here call edge) to save battery.
I dont see it anywhere in settings so i wasnt sure what people did..
Thanks!
I think you mean 3g to 2g. This phone does not have "4g". It's just 3g with higher throughput.
I'm not sure if you can on the stock rom without a USSD code. But on custom roms it's:
Settings
Wireless and network
Mobile networks
Network mode
GSM only.
Unfortunately apps like llama/JuiceDefender can't do it automatically when you're on WiFi or not using data because Google "blocked" it. I think CM7 allows apps to control 2g/3g toggle though.
I thought if your wifi was on the 4g was turned off.
Also, on stock 2.5.- the system folder for wireless settings has a choice to only use the edge frequency. I don't know for any of the modded roms or the newer stock 2.6.- versions. Hope this helped.
T-Mobile uses 3.5g(which they call it 4g) a more advance 3g speeds so a with a 4g/3g toggle wouldn't do any good unless you wanna go to edge/2g. is not like Verizon where I think you have your Band for 2g/3g and a separate Band for 4g so what the toggle does its just turn off the 4g Band and automatically goes to 3g. but with Tmobile your have your Bands for 1g/2g and another band for 3g/3.5g(fake 4g) so using a toggle you would only be blocking 3g.

WCDMA only loses data

I'm using Darthstalker Note 3 V6 and Advanced Signal Status to switch between LTE or WCDMA. The problem I'm having is that sometimes when streaming data through Spotify or watching YouTube, WCDMA mode loses data connectivity. It usually happens after a prolonged period of use, but WCDMA just will just stop working not connect to 4G data anymore. I can still make phone calls and send texts, but internet and apps that rely on data just don't work. Signal strength shows normal, but the 4G is just dead, the indicator is not there either. However, if I'm in an LTE area I can switch to LTE and everything will be fine. Its like WCDMA just stops working for a few hours.
LTE coverage in my area isn't nearly as good as WCDMA and I prefer reliabiliy more than speed. Any help would be very much appreciated.
Switching airplane mode on/off - doesn't work
Turning the radio itself off through Advanced Signal Status - doesn't work
Reboot - doesn't work
Battery pull - doesn't work

LG D855 takes time to connect to 4G

I have the following issue with my D855:
When I reboot or power on the phone it display the search for network icon for few seconds and then it connects to H+. After an hour or so it connects to 4G. All the phones I used connect directly to 4G. I have 4G coverage (when it connects I have full bars), compatible 4G sim (works great in other phones) and carrier settings(set up and verified by Vodafone representatives). Also while on 4G when I connect to WiFi it searches again for network and when I turn off WiFi searches again for network and happens the same(H+ and after an hour I have 4G)
Any ideas why this happens?

Little to no 4G LTE connectivity on MetroPCS

So I'm wonder if anyone else has been having a problem with their 4G on MetroPCS. Like I've been having trouble receiving calls and using my 4G data. But if I go in my mobile networks settings and set my Preferred Network Type to 3G or GSM/WCDMA, I can get calls but I can't use data at all. But if I set it to 4G/LTE it works for a bit but the signal just slowly dies to just 1 bar and I can't do much except make a call.
