First of all, thanks to everyone concerned for this thread. Fast Dormancy is something that I have been interested in since my Nokia N95 days.

Getting information from my carrier is like banging my head against a brick wall. To give you some idea of what I'm up against, this brief thread by another poster, on the Vodafone UK forum, typifies their attitude, see here.

Phone... Samsung Galaxy S2 (GT-i9100)

Carrier... Vodafone UK (Cotswolds, England)

Firmware... Android 4.0.3 NEAT ROM, stock based, deodexed.

Kernel... Siyah 4.1.5

Modem... BVLP7 (GT-i9100P modem) Identical read with Vodafone BULP7 modem.

With Google Search page loaded and using carrier timings...

WCDMA 2100 Band 1:

(Average times)

T1: DCH to FACH: random

T2: FACH to PCH: 30 seconds

T3: URA_PCH to IDLE: never

Phone cycles through FACH - URA_PCH 30 seconds and then back to FACH after 30 seconds with the occasional, random, DCH.

Setting the timer to 15 seconds and rebooting gives:-

(Average times)

T1: DCH to FACH: 10 seconds

T2: FACH to PCH: never

T3: URA_PCH to IDLE: never

Cycles from DCH - FACH 10 sec's FACH - IDLE 8 seconds IDLE - DCH 30 seconds

Big battery drain on this setting.

Please keep up the good work as this has been bugging me for years and I would love to get some real answers. :good:

EDIT

Disabling FD on the phone and rebooting gives me... the identical readings to FD enabled with carrier settings??? Weird! :confused:

Just re-checked... Voodoo had re-enabled FD after boot even though my phone is saying FD disabled.

UPDATE

No matter what I do I cannot change the above readings for my carrier, whether FD is enabled or disabled. I have wiped cache and dalvik and even wiped cache and data in Voodoo as well as un-installing Voodoo and my readings for FD enabled or disabled remain identical.

Phone cycles through FACH - URA_PCH 30 seconds and then back to FACH after 30 seconds with the occasional, random, DCH.

Hi I'm using latest Jelly Bean leak (LH1) on my Galaxy S3 and when I install this app the only thing I see is two buttons. No fast Dormacty toggle or timing options?!

Does this mean the app doesnt work on 4.1.1 ?

Thanks!
[Networking] bordikun:
Will the "secril_fd-interface" wakelock not supposed to appear in BBS if your carrier support FD and enabled? Becuase mine appears and people said that my carrier has FD support so which is which?

Using Galaxy S2 with JB, when I enter the app it only shows my network ID and Network name and a gray 'Apply!' button... What do I do?
[Networking] joederp:
Don't know if any plans to support non i9300, but I check my T999.

supercurio app doesn't work because TMO Samsung doesn't support *#*#9900#*#*

com.android.providers.telephony / nwk_info.db

-------------------

nwkinfo - "dormancy = off" for T-mobile

dormpolicy (for T-mobile / Vodaphone)

lcdonfdtime = 0

lcdofffdtime = 0

lcdonfdtime_Rel8 = -1

lcdofffdtime_Rel8 = -1

dormpolicy (for AT&T)

lcdonfdtime = 0

lcdofffdtime = 3

lcdonfdtime_Rel8 = -1

lcdofffdtime_Rel8 = -1

But I know fast dormancy is on, because I can watch it go from 3G->HSPA->HSPA+ and back down with no data.

Also phone is killing battery as top user.
[Networking] rocketsbay:
Hi MPKO,

Do you have an idea of which/how many devices support network controlled FD?

I suppose it's chipset related. If we can identify chipsets which which do support it, can we assume that all devices using that chipset actually have network controlled FD configured?

If a network is NCFD enabled, what happens when a non rel8 devices requests the release of the signalling connection? Will the network obey as in pre rel8 or will the network try to move the device to URA/PCH?

Also, just for confirmation, in URA/PCH or CELL_PCH, the RRC connection is still present right?

Thanks
[Networking] Bifurcator:

on my SGS2 with PA (CM10) i can get into the servic mode by typing *#*#0011#*#*

BUT *#0011# or the other codes *#9900#.... do not work.

have fun
[Networking] ddrt:
SGSII E4GT Sprint *#0011# brings up service mode and tells me to use the hard back key. Shows rows but no information in them. Wifi off 3G selected. clicking rows highlights them as if they are to have some function but it doesn't do anything other than that. Might have something to do with the fact that I just went back to stock so I could upgrade to ICS? Maybe? Do you have to be rooted to take advantage of Service mode and see the information it could provide?

I'm betting, since the service in my area is, honestly, worse than it was when I was 16, that it's just the local Sprint outfit. Their coverage is about a five mile stretch around a mall, completely ignoring the rest of the city and causes you to roam about 45% of the time. Really doubt they've got Fast Dormancy set up correctly.

EDIT: *#9900# allows me an array of choices from delete dumpstate/logcat all the way down to ramdump mode disabled/low. I see disable fast dormancy (current state: enabled). Wow, this is a pretty cool screen to have from a key shortcut. I wish there was a widget shortcut to get to this.
[Networking] treklos:
I'm curious, is there a guide to what each fast dormancy value means in "ro.ril.fast.dormancy.rule = x"

I'm having data connectivity issues with my HTC One S and I would like to modify the fast dormancy rule, but I dont want to arbitrarily change values and guess at the possible outcome.
[Networking] leingod:
Interesting guide and detailed explanation. However I cannot identify whether if my network Starhub support FD hence I did a test on battery drain for 3 night just before I went to sleep.

1st Night (FD w 15 sec timer Policy)

Better Battery Stats

Since: 8h 1m 22s

Battery: 28% (40% to 12%) (3.5%/h)

Deep Sleep: 4h 4m 10s

Awake: 3h 57m

secril_fd-interface Wakelock: 3h 38m

Was disappointing as I almost conclude my network doesn't support FD.

2nd Night (Without FD)

Since: 8h 25m 27s

Battery: 29% (52% to 23%) (3.4%/h)

Deep Sleep:3h 36m 35s

Awake: 4h 48m 52s

secril_fd-interface Wakelock: 4h 27m

Not much difference and I was about to conclude... However...

3rd Night (FD w/o timer Policy)

Since: 8h 19m 31s

Battery: 9% (72% to 63%) (1.1%/h)

Deep Sleep: 7h 40m 10s

Awake: 39m 20s

secril_fd-interface Wakelock: NONE

I'm amazed by the huge improvement and the awake and secril_fd result. I'm going to do one last testing tonight, FD with timer policy again. I'm not sure what benefit or what does it actually do. But what I know turning it off certainty making me confirmed that my network do support FD.

As AngleofMusic video explained about the RRC state. I can't observe much difference with FD and without FD as it always go from DCH to IDLE only. No other state was observed. Only a short moment of IDLE_CCCH appeared when FD was on but rarely.... Timing for the states all vary with or without FD.

Hence maybe expert here might able to find out something for me or maybe I might hope to contribute my finding for my network to anyone who is using the same as I do.

*Edit: Btw I'm using GT9100 (S2)

Thank you so much. That video was so helpful and has made my battery life last so much longer!
[Networking] Many40:
Hi, my carrier supports FD and when I enable FD in my phone the wakelock is shown in BBS but very short one as yours a few seconds (that's I think OK).

However if I disble FD in my phone - the wakelock lasts endlessly draining battery very much,

So from my experience you shouldn't worry - your carrier in my opinion supports FD.

BTW, great video and thread. Now I understand much more about this topic then before.

Regards

Ps My setup is as in my sig and the app "RRC tool" still doesn't go to service mode but to the dialer - but it's not a problem for me - I just dial then manually the code :)
[Networking] omniwolf:
Hi,

I have just done a set of tests on the Telstra network.

3G networks - tested on both an i9300 and an i9305 set to WCDMA only

Fast dormancy disabled on the phone

Cycle: DCH -> FACH -> URA-PCH (it's UPCH on the i9305) (-> IDLE)

T1 (DCH -> FACH): ~3 seconds

T2 (FACH -> URA-PCH): 55 seconds

T3 (URA-PCH -> IDLE): dunno, i waited 4 minutes and it didn't happen. maybe IDLE is never hit while the screen is on? dunno.

Fast dormancy enabled on the phone

Cycle: DCH -> FACH -> URA-PCH (-> IDLE)

T1 (DCH -> FACH): ~2 seconds

T2 (FACH -> URA-PCH): 3-5 seconds

T3 (URA-PCH -> IDLE): dunno, as above.

So from this I infer that fast dormancy is available and should be used.

Then i tested on the 4G network:

LTE network - obviously tested only on an i9305

Fast dormancy disabled on the phone

Cycle: CONN -> IDLE

T1 (CONN -> IDLE): 35 seconds.

Fast dormancy enabled on the phone

Cycle: CONN -> IDLE

T1 (CONN -> IDLE): 35 seconds

Does this make sense? Can I measure LTE the same way we do 3G? it looks like the 4G network does not have fast dormancy, but I dunno if 4G can even HAVE fast dormancy??

Thanks in advance for any replies
[Networking] angourakis:
I have another question: Observing the behavior with FD enable / disable, I also saw that when the network is using DCH state, the WCDMA band is 850 Mhz (I also have a stronger signal).

When it switches to the lower states (which in my case the lowest is URA_PCH, it only goes to IDLE if Wifi is on) most of the times, the band switches to 2100 Mhz (and give me a worse signal)

Do you have any idea why it happens?

My carrier is Claro Brasil (72405) and it supports DCH, FACH and URA_PCH

Best Regards

This can work on i9100G?
[Networking] angourakis:
It's applied to, practically, all Samsung devices running, preferentially, the stock ROM. My Galaxy S is running CM10 4.1.2 and I could check by modifying the build.prop file, restarting the phone and checking w/ Service Mode typing *#*#0011#*#*

The ServiceMode.apk file has to exist in the system/app folder or you won't be able to check the RCC status

Will it help me on sprint?
[Networking] angourakis:
Sprint is CDMA isn't it? I'm not sure, I think it's applied to GSM (3G/HSDPA) only.

I think people didn't understand completely what Fast Dormancy is. Shortly, it helps you to save battery by switching to less consuming states when transfering data or during idle state.

When not supported by the network operator, it switches in certain amounts of time. When FD is supported, it can switch inteligently from the lowest to the highest state and vice-versa.

Take a look at the video at the beginning of this thread. Maybe it does not apply to you but it's a knowledge so it's not wasted =)

angourakis
[Networking] Laynee1:
One question :

Im on Telenor, Serbia. I called them and they told me that Telenor does not support FD. So i should turn it off on my note 2 right?
[Networking] angourakis:
I'd recommend you to take a look at the videos and see, truly, if it's supported or not.

Normally people (read carriers attendants) don't know even what you're talking about so it's better to check it twice.

[Networking] carlos67:
ok, I've read the whole thread and it's time to dip my toe in.

I'm on Vodafone UK and I am not sure if this carrier supports FD or not. So, using GokhanMoral's FD toggle app (because it's in my rom by default) I observed the rrc states in both the enabled and disabled states. This is what I observed..........

Fast Dormancy On

Open internet page and state jumps to DCH, then shortly after FACH, then after approx 5 seconds PCH where it stayed permanently.

Fast Dormancy OFF

(reboot after toggling)

Open internet page and state jumps to DCH and remains there permanently.

I may be wrong, but this is what I conclude from this observation.

1. I am better off having FD enabled because with it on my phone goes to a low power state i.e. PCH (although never to idle - is that a bad thing???).

2. With FD disabled, my phone stayed at DCH and I believe this is a highly active power hungry state and will eat my battery for breakfast.

Guy's and gal's, please tell me if you think my conclusions are misplaced or if you can tell from my findings wether or not Vodafone UK seems to support FD or not. I would say it doesn't implement NCFD because if it did, it would have reduced the rrc state from DCH after a short period of inactivity.

Any comments/replies welcome and greatly appreciated :)
[Networking] Laynee1:
My phone goes from DCH to FACH then to PCH .. What does this means?

Handwritten from my Note 2
[Networking] omniwolf:
your conclusion is correct. keep FD enabled.

i think you'll find if you wait long enough with FD disabled it will eventually drop down to FACH and PCH.

I never saw idle in my 3G tests either, but I read somewhere that IDLE is potentially only reached when the screen is off, so you'll never actually be able to witness it.

the only conclusion that can be drawn from your extremely limited report is that your phone is correctly moving down power states. whether FD is available on your network is yet to be seen, you have to record the amount of time spend in each network state when FD is enabled on your phone, and when it is also disabled and see if there's a difference.
[Networking] Laynee1:
Thanks mate! I asked my network provider and they told.me that Fd is not available on Telenor Serbia..

So i should disable it right ?

Ill check that videi once again and see what happends with timers..

[Networking] Be.R7:
If I only use 2g only, so I can delete the fast dormancy app from system?

Because the 3g network in my country is unstable an expensive.
[Networking] omniwolf:
if you don't have FD on your network, then yes you should disable FD on the phone.

you can delete it if you want, but it's a passive app, so don't fear it draining your battery by just sitting there.
[Networking] Laynee1:
That app you showed in Fast Dormancy Whole story (voodo rrc or smt like that) is not working on Note 2 . The slider is not available and apply button is grayed out..

Any one knows why ?
[Networking] omniwolf:
because it's not written for the Note 2. it doesn't work on JB at all i don't think. Just user the service menu thing to check the RRC states as explained in the video. I had to do that too for my i9305
[Networking] PIRATA!:
I'm sorry...I'm using Voodoo RRC tool but I can't see any FD slide to set the seconds and my apply button is grayed....

Why?

FastDormancy Toggle app says that I have FD enabled...

Here is my situation:

3 Italia:

WCDMA 2100 Band 1:

T1: DCH to FACH: 10/20 seconds

T2: FACH to IDLE: 3/5 seconds

No other Time and seconds up here are not always the same.

How can I really understand if my network has Fast Dormancy??
[Networking] omniwolf:
Yep I had the same issue when testing on my phone. Follow the youtube video, it expains how to test your network without the slider.
[Networking] PIRATA!:
Yeah, but also that I have noticed that in my database system files I don't have my APN info!!

I have read the old guide how-to on how to edit timings manually and I have found that I don't have anything mentioning my network code!!

Should I add it manually editing that database file or should I forget about it??

I think I sold edit my timing as I have alot of wakeups and my network should have Fast Dormancy enabled!!

A question..

Tried contact you Erica on youtube with no luck.. Try XDA forum see if you have time for a moment...

Would like some tips on a good cheap camera that can shoot very close to a objects with a good focus ... The one I have now does. But when it comes to recording such as android screens or monitors, they are not in focus. It loses everything, sharpness, color, focus, etc. ..

I record flowers, newspapers and other stuff verry well... But it is old now, and I need a new one ....I had set up my camera to do a review example of a Nexus 7 and Galaxy note. Just to show you so you get some details ... You see ourselves how bad it is (video link) .. try to adjust the camera at the end of the video, but no luck ...What I want is something cheap (as cheap as possible), that can make videos in 1080p on near objects like screens etc without losing focus when the screen lights up and goes out ... You know what I mean, I hope ... Otherwise write comment ...Thanks ...

Hello. Sorry for my bad english.

I don't know if I have a Fast Dormancy issue.

I have Samsung Galaxy S3. This is my battery stats:

Deep Sleep 10 h 22 m

Awake 30 m

Screen On 1 m

Multipdp 37 m 44 s (2264 s) Cnt: (c/wc/ec) 356/0/356 5,3%

Is this normal? Thank you.

Update. My provider wrote that Fast Dormancy is enabled. In service mode I receive these timers:

DCH (10-11 sec.) FACH (42-43 sec.) URA_PCH.

Voodoo 3G doesn't work on Android 4.3 stock firmware, Galaxy S3.

Hi there!

Thus thread Is quite old, but I'm gonna ask this anyway.

I my Samsung Galaxy S3 I was using to disable Fast Dormancy.

Now that I'm on S5 and same provider/carrier...I should be able and should go for disabling Fast Dormancy as I was doing before...right??

About the technique...same app made for S3??

Tnx to all.

For anyone having the infamous left side screen lift issue. This includes being able to physically see the glass protruding the silver bezel, screen sponginess, and being able to hear the screen stick/unstick from the adhesive.

After reading this thread http://xdaforums.com/showthread.php?t=1800418 it is apparent the screws are a hair too long. When tightened all the way, they actually can press the screen glass out.

The easiest thing for anyone to try is to just LOOSEN the screws just 1/4 turn. You are loosening the screws so very little, that they will stay snug as far as holding what they are supposed to, but they will no longer push out on the screen glass. I didn't even bother with finding a screw driver, and just used my pocket knife. My screen was raised in the very middle of the left side, so I only loosened the 2 screws directly under the seperation. I suppose this will not work for everyone, but it's so simple and only took me less than 2 mins, you might as well give it a shot. Good luck!
[Nexus 7 General] Vanpeebles:
Great thanks
[Nexus 7 General] mi7chy:
If you're going to loosen screws you probably want to Loctite them.
[Nexus 7 General] ferris2375:
http://xdaforums.com/showpost.php?p=29457665&postcount=41

eh hem...what gave you this idea? jk

Just don't overdo it and you'll be fine. No need for loctite, it's only a small turn and the screws are still plenty secure.

---------- Post added at 12:29 AM ---------- Previous post was at 12:28 AM ----------

Loosening the screws in some areas will also help with backlight bleed. If you notice a spot near a screw that is really bright, it's most likely a little too tight.

I found this out by testing different "tightness" adjustments. When I went too far, I noticed back light bleed starting to show, loosen it up a bit and it went away.
[Nexus 7 General] EvoRocker:
This actually worked! So far, anyway. We'll see if it's a permanent fix, but it looks promising.
[Nexus 7 General] jaycustom:
Lol yeah I saw your posts. I mean, that's the same thing I thought of right away. The washers seemed to be a stiff foam, so they compress when screws are tightened. I figured I could loosen them but at the same time keep them snug.

But yeah man good stuff. Did it work for ya?
[Nexus 7 General] jweitzel24:
This.

The washer idea is smart, but for me it caused a more annoying problem. The frame was too thick and pulled the silver trim piece away from the screen and caused a creaking noise at the slightest touch that was way worse than the screen lift.

I just loosened every screw and tightened them back with basically no torque after they stopped turning. All is good now, no creak from the trim and no screen lift, though it's basically flush on he left side

Sent from my Nexus 7
[Nexus 7 General] jaycustom:
Cool. So did you end up loosening the screws then? Meaning, when you re-tightened them, you didn't tighten them as tight as they were from the factory?

Very interesting... I thought the glass was supposed to be flush with the bezel, until I read your comment. After looking at it, the left side of my glass is also flush with the bezel, while the right side glass sits just a little lower.

That's no big deal to me though, as long as my screen is seated properly.
[Nexus 7 General] jweitzel24:
Probably a little lighter than factory. Honestly, mine wasn't bad to begin with but like every other ocd person on here, I just couldn't resist opening it up and tightening the screws. At that point, the screen lift started getting worse and I moved on to the other half-dozen or so "fixes" when, it turns out, the screws being too tight was making everything way worse.

But yeah, its been a couple hours now and it still feels real solid. I've got a tpu case on order so regardless I'm done messing with it.
[Nexus 7 General] jaycustom:
Cool beans. Luckily, like your N7, mine wasn't bad either.

Couldn't really tell it was lifted by looking at it, but it was the sponginess and that horrible stick/un-stick sound. This is the first fix I tried, and luckily it worked. Let me know how yours turns out, with or without the case..
[Nexus 7 General] MikeMurphy:
I simply loosened all screws then tightened them up. Also, Part of a sponge bumper was tucked under a copper shield which I untucked.

Now when I push hard on the left part of the screen I don't get the tacky sound when i unpress it. Also, screen isn't as bulged. In fact you can't even tell anymore.

Neither was a real problem on my n7 but I prefer to make it perfect. This solved everything.
[Nexus 7 General] jaycustom:
Awesome. Mine wasn't bad either, so I just tried for something simple. It seems like the screws may be too long and pressing on the glass, so I thought to just back them off a hair. 2 minutes later the screen is perfect:)
