[Q] 4G always on! - Galaxy S 5 Q&A, Help & Troubleshooting

Hi. On my gm-g900i (australian) s5 i have the latest XtreStoLite installed with the correct bootloader & modem.
For some reason at all times it shows 4g in the status bar, even when i am not in an app that requires internet. It will only drop to 3g when i am in a poor signal area.
Why does this not dynamically change based on apps used, as it did in kit kat? Have i done something wrong? I am after the power saving of 3g for background data, then 4g when using an app like facebook, chrome etc. This was automatic before?
thanks in advance.

If you're in a 4G enabled area, it'll connect to 4G
If you don't want it to, disable mobile data

Control 4G/3G/2G by app?

Hi all - I'm on the cheap Tmobile plan (500 mg/month) but I really don't need 4G that much. Ideally I'd like 4G to only run when in the web browser, youtube, etc - when I really need fast speed.
If I'm in google music, facebook, reading email, etc - I really don't need FAST speeds - 3G is more than fine.
Anyway to set up 3G as the normal radio, then auto-toggle to 4G when specific apps open?
Ideally I'd only like to use the fast 4G when needed, like downloading videos, youtube, etc.
I don't remember if you need to have your phone unlocked for the menu to be enabled but it's under System settings -> Tethering & networks -> Mobile networks -> Network mode.
You can also run the *#*#INFO#*#* code -> Phone information.
You may want to check with T-Mobile if switching to GSM mode will stop you from using up your 4G allowance (if that's what you're trying to do). I've seen no indication to that.
Re-reading your post, there is no 3G mode anymore, since they upgraded 3G to 3.5G which they call 4G. So your choices are either GSM (2G), WCDMA (4G) or LTE.
All data usage counts against your quota, even 2G. Your phone is not going to use more data simply being on LTE. The proper way to manage data usage is to disable auto-sync and turn off mobile data entirely as much as possible.

I use (2g-3g on/off) widget from the playstore. It places a widget/shortcut on your home screen, that takes you to a settings screen that allows you to toggle between 2g, 4g, and lte. Works great on my T-Mobile G2.
tasker, how dunno but look into it

I think if you install the Secure Settings plugin you can use Tasker to automate it.
Doesn't GravityBox have the smart radio option? I didn't have much luck with it at first, but seems to be better now.

Okay so for Tmobile, no matter how I get the first 500mg of data (3G,2G, etc.)- that's when the 4G shuts off? I thought I might be able to "save" 4G until I really needed to use it.

That's correct. Also, 4G doesn't really shut off. You will still be on LTE or HSPA+ when available, but the speed will be limited. The system doesn't actually kick you off 3G/4G it just reduces your speed.

Okay that makes sense - so I'll still be on 4g (orlando) but just throttled at 128k or less. kk thanks

4g / LTE Toggle / radio control

At work the 4g LTE signal for ATT is very poor in the building, but we have 4g repeaters for ATT to fix this issue. Unfortunately, phones are stubborn and like to stay on 4g LTE despite having 1 bar of signal vs full signal with 4g. I had this same issue on my iphone 5 but was able to easily force off LTE while i was at work and have a steady, reliable data connection. My Note 4 seems to have the same affinity to wanting to be on 1 bar of LTE, but I cannot figure out a way to toggle / force LTE off and just use 4g. Anyone have any ideas? Anyone know of an application I can use to resolve this issue?
Thanks
try settings...more networks...mobile networks....network mode....It should be in there..I have the sprint model so I don't know for sure...but that is where mine is....hope this helps

Unfortunately, there is no option for Network mode on the ATT version. I wonder if this has to do with voLTE....
I did find a backway to the network mode via *#*#4636#*#* but I am unsure of what I should be setting to "disable" lte while I'm in the building at work.
I think I've sorted this out now. If I change LTE/GSM AUTO to WCDMA preferred it seems to immediately switch and hold onto 4G. I do have to change it back. Maybe I will write something so I can quick toggle this since nothing on the app store seems to work.
hi,
If you are rooted ? You can use an xpose module called Intelli3G
I use it on my phone ,works 100% and switches smoothly/fast between eg 4G..3G automatic
eg if my data is of its on 3G as soon as i switch data on /wifi it changes to 4 G
For interest sake ,here is a link to market ,you can read desciption what it does ?

4G icon

Hello, This may be a simple question, but it's puzzling me at the moment.
I have a Galaxy S4 , rooted and running Hyperdrive 21. I haven't changed any setting in the past few weeks. For the past couple of days, the 4G icon will show up in the top bar, while on WiFi. It has never done that before. When I connect to WiFi the signal indicator was always there, but the 4G icon was not. I always relied on this to know if I was using my cell data or WiFi. Now I don;t know if the phone is using 4G or Wifi?

Mine will only show the 4G icon when I'm sending or receiving a MMS at home on WiFi. Could that be what's happening?
No, I'm not sending or receiving a mms

Data not working at all when connecting to 3G?

I have recently gotten a new data plan (before I had like 500MB so I didn't even bother with using mobile data) and started using mobile data a lot more. I have found however that when I get 3G signal (it displays 3G in the status bar) no data actually gets transmitted, and I have to keep going until it connects to 4G or H for it to work again.
What can be the issue? I'm on EE, running the latest Pure Nexus ROM and ElementalX kernel with the Amanuensis profile. Thanks!

Problem with LTE data connection

I have the Sprint variant, G900P.
Data via wi-fi works consistently and well; mobile data is the problem.
Data via 3G works most of the time but data via LTE does not work - apps show 'unable to contact server'. This is not related to signal strength or a specific tower. LTE lights on the notification bar, but no data transfers. Occasionally, but not consistently, if I cycle 'mobile data' then a data connection establishes in LTE but soon disappears, even tho signal strength and LTE connection remain.
Is this a modem problem? Phone is rooted and running a slightly debloated stock 6.01 ROM (CQD1).

You may want to contact sprint to make sure its not your SIM card or the modem itself going out.
You can try and wipe the phone and go back to a regular stock, it may or may not help tho.
