Hi.
I suspect that my current network operator doesn't support the 'fast dormancy' option for mobile data, so I've been trying to find a way to disable it, but to no avail.
I read that if your phone has fast dormancy enabled but the network operator doesn't support it, that means bad news for your battery, which I've found to be true in my case.
When I'm off wifi and on mobile data, if I leave the phone with the screen off for long periods of time, I get the "msm_hsic_host" wakelock, which I've found to be directly related to 'fast dormancy'.
I tried using the *#9900# dial code and disable it there, but it seems like the option is not available in there anymore.
How do I go on about disabling fast dormancy in a non-rooted phone?
My phone: Samsung Galaxy S4 i9505 (non-rooted)
ROM: Stock Lollipop 5.0.1
Kernel: Stock
P.S.: For anyone wondering what 'fast dormancy' is, here's a video explanation for it.
I don't think you can on a non-rooted phone.

Hey guys.
Iv been reading a few things regarding fast dormancy and switching it off improves battery life and network speeds, but im unable to find this hidden dialler menu.
*#9900# doesn't do anything, when I type it, it just disappears - no menu comes up.
What am i missing ?
Im on Lite'ning ROM 1.5 KF2 modem and Kf2 kernal
Thanks guys
*#*#9900#*#*
Thanks for the reply but that also doesn't work, nothing pops up at all....
Make sure that you are using the stock dialer, not another one you have installed from the market afterwards.
It is stock dialler, I haven't changed that ever. Im starting to think maybe its network related ?? Im with Optus Australia, maybe they don't support it or maybe I have different dialler codes ?? Thanks for our help
Network errors while sync or Dropbox
When Fast Dormancy is disabled; I keep getting network error messages while I sync Dropbox files to my device. Whne enabled, everything is fine.
I did not notice any such issue with other data applications.

That works for me, and is how I disabled fast dormancy a couple of weeks ago. I can only assume that it's something to do with your ROM or FW.
I'm on stock, KE2.
FIXED!!
I fixed it by installing Infusion 1.2 by Nitroz ROM his rom is awsum !! now my battery lasts even longer and have wayy better network speeds.
his rom is can be found here http://forum.xda-developers.com/showthread.php?t=1152693
Thanks guys for the help anyway
I've read in various places that if the network has the Fast Dormancy feature enabled, but the phone does not (or vice-versa), this will have a negative impact on the battery life of the phone.
Can anyone substantiate this claim?
Also, is there a way to tell if this feature is turned on in the firmware of my phone? I purchased my phone unlocked from an independent retailer, so it doesn't (AFAIK) have a network specific firmware image loaded.
I'm also unsure if my provider (Vodafone Australia) has FD turned on or off on their network or how to tell.

Hi,
Just bought this crazy SGS4. Everything works very great (exepect Tasker doesn't reconize my ROOT when Titanium do...)
I have only one big trouble Internet stuff (as play store, browser...) load data only when connecting to H+
So when I open anything i have to wait H+ connection (1 second to 6 seconds sometimes) then when it's loaded it goes back to H and between every click i have to wait it to connect to H+...
Any idea, fix ?

Same issue
i used to have this problem on my galaxy note, i disabled some setting in the developer menus, the ones where you have to type in a secret code into the phone app. I disabled something to do with hspa but can't remember what the setting was but it did the trick, im on vodafone uk
I found any of those settings in devs settings.
The Idea is good switch to H when it's not in use (to prevent battery life) but not a second after the loading and sometimes during the loading that makes impossible to load the page...
Moreover it's strange I can't load any page with H because it shloud work
If you are rooted, try to disable fast dormancy. I had unstable data connection on my note 2,which constantly switches between H+/H/3g because my carrier does not support fast dormancy. The fast dormancy app works well on galaxy s4 aswell.

Yes rooted.
Thank you for the tip. It appears to be better. I will make some search about fast dormancy I didn't know this before you tell me.
I keep you in touch
hy guys, i'm an italian user, same problem on my new galaxy s4 white. i didn't get it in my phones (S3, S2, Note2), but in this S4 is terrible, because it takes many seconds to connect to various app.....
i've called the Samsung support, they tell me to try to put it in Safe Mode for some days by clicking many times the button menu, but i can't put it in that way...
have you found any solution for fast dormacy mode?
thanks
I recently bought Samsung S5 G900F from a friend which updated it to latest lolipop 5.0 software, and after that wifi stoped working.
It was never rooted or etc. When i try to turn on wi fi i press button for turning on freezes and it doesn't show any wifi network. By my friends words it started after updating to lolipop. First i downloaded and flashed two 4.4.2 from sammobile and i there's no difference at all.... Second thing i found thread with latest modem on xda and nothing at all.
The only thing that helps for short while is from unkown reasons when i switch SIM cards it starts working but speeds are 200,300kb/s and signal is very low. And from some secret code went to wifi settings and turned off battery saving mode, it helped to now more often it works but for short while and slow speeds.
I don't have any ideas, what to do with it all sings show that it is software issue. Thanks in advance on replies
This erro my phone not my eny solution.?
Hi there,
First of all, I ran an extensive search over google and also on XDA forums before posting this.
My S4 (I9500) is experiencing random data connection drop problem for some time now. It starts with no data transfer (upload/download arrows not being active), then connection goes from H+ to H, then to 3G, then drops, back to H and continues until I turn off and on MOBILE DATA from toggle buttons. Then it works normal for some random time, then it happens again. Sometimes an hour, sometimes after 5 minutes.
I found this thread , however trying the workaround there by entering the provided code, I get "Connection problem or invalid MMI code". So that fix is not working either. I tried to go in service mode > debug screen > nas control and change revision to Release 5, but it says NOT SUPPORT. Haven't tried the other releases since I dont want to mess with it. I am also aware that the workaround in the above thread is for S2.
When this happens, it is just mobile data, there is no problem with network signal.
Has anyone else experienced something like that on their S4s?
The method you tried using is probably outdated and for a different phone.
Are you sure it isn't your provider?
Did you try another modem?

Nope.. I am working for a service provider company. Other people with iPhones in the same location as I am, are not experiencing the same thing. I heard similar problems with other S4 users, but they dont know any workaround either.
I tried both auto connect and WCDMA only options as well. Doesnt make a difference. My S4 doesnt support LTE, so I only have 3 options, third as GSM only, which I don't think it would be a solution.
Only temporarily solution so far, is turning mobile data off and on, which lasts from 5 minutes to 1-2 hours.
Btw my android version is 4.4.2
