Hi guys, I've posted regarding this issue on a thread somewhere but not getting much hits. If you have 3G Data enabled then put your SGSII to sleep, and wake it up, do you see the Data signal as 'H' or '3G'? Mine wakes up and it's on 'H'. My phone is rooted, using Lite'ning ROM 2.2 XXKG1. I compared with a friend's SGSII with everything stock and not rooted, same thing, wakes up on 'H'.
The phone should switch to 3G when sleeping / stand-by to save battery... but for some reason, each time I wake my phone up, I can see 'H' on the Data Connection instead of '3G'. If I unlock my screen and wait 5-10 secs, Data then switches to 3G. But if I lock it and unlock again, it's back to 'H'. I believe this has been draining my battery more than when I have WiFi connected.
Widgets I have running is Beautiful Weather, refresh every hour, did NOT check refresh on wake up. Google Auto-sync is on. Fast Dormancy is on. I have once tried switching all of these off, reboot, but still same thing.
I've searched for this issue on google, this whole forum but just can't find a post discussing about this issue. Maybe I didn't use the right keywords... I've been searching: "samsung galaxy s2 sleep 3g hsdpa" , something along those lines. Of course I tried combinations like just sleep 3g or sleep hsdpa etc.
If there is a discussion regarding this, could you point me to it please or suggest keywords to search for, thanks.
Maybe this you need,

Hi, I'm currently using ICS Passion v10.6. I do not have a data plan, but am always connected to wifi at my house (router is usually about 3 feet from my phone).
Often my phone will lose google connectivity (wifi and signal bars will go gray), and often, usually when i leave my phone untouched for a while and then check it, i will notice that wifi had been lost and it does not reconnect until i turn the screen back on. I have the wifi sleep policy set to never sleep (keep wifi on: always), and the battery info says that the wifi is constantly on.
I was wondering if a different modem would help or if it is a bug in the rom itself or the kernel? My wifi and google connections would constantly be on 24/7 when I was running bionix v1.3.1. I've tried flashing the KB1 modem which bionix uses, but i get the same result.
Thanks for any help
Hey Devils,
I've had some of the same issues, aslo using 10.6. If I leave my phone alone for a bit it seems to stop getting notifications from data. The best example of this is I use Trillian IM and I can be chatting on it. Finish. And put it aside for awhile and not get any notifications and then when I hit the power button all of a sudden I've got 30 IMs waiting for me.
I have tried several different Vibrant ICS modems from this thread but they all caused big issues for me. some caused massive power drain but all of them caused my lock screen be unresponsive when I hit the power button and I'd have to wait for the screen to blink out and hit the power button again to be able to get access. The same would happen when I get a phone call, sometimes the screen just would not respond when it lit up for an incoming call. I think it was because it would start searching for data connectivity (so it seems related to the problem which makes me think it's not modem related)
In the end, I went back to the KB5 modem and my screen issues seem to have resolved. I may try Passion 11 soon and I'll post results if it helps, but right now I'm not ready to do another change on my phone.
-update- I just checked and saw that v12 is out now and has both a kernel update and an update to wifi. I'll probably try that tonight.
-update- I think this might be being caused by "Deep Sleep" causing the phone to shut down it's data antennas to turn of to save battery. I've installed "NStools" on my phone and set it to set the min CPU freq. to 200mhz to see if that will prevent deep sleep. I'm not certain this tool will work 100% on this build, but we'll see I guess.
I'm also running the Vibrant without data, using wifi to do things with the internet.
Since flashing ICS I haven't had any wifi issues on the two networks that I've used. Seems odd that you are now having them. Have you tried a different hotspot?
I have had issues sending text messages. I can place and receive calls, receive texts but can't send any. Have you had any of these issues? I'm curious if it has to do with the lack of data plan.
I posted a question about this last week thinking it was a wifi problem, but it turns out it happens when I'm on data too, so it's an overall data problem... I'm just using wifi most of the time so that was the only place I had noticed it.
Occasionally my phone will stop being able to send/receive data. I'll turn it on and try to load a web page, for example, and it will just hang. Turning wifi on/off doesn't fix it, and turning data on/off doesn't seem to fix it either. The only solution I've found is going into airplane mode for a second. The frequency varies.. it seems to happen between 1-5 times a day, so it's pretty inconvenient.
I've read around a bit and it sounds like it's caused by the phone trying to get a 4G connection but it isn't able to or something, so it just hangs there and never lets the 3g/wifi connections get used (due to priority of connections or something). I almost always have wifi and don't care that much about data speeds, so if disabling 4g altogether would fix the problem I'm game (although I'd prefer another solution...). I tried the *#*#4636#*#* code to change it to GSM only (I read somewhere that that'll disable 4g), but it instantly reverts back to what it originally was, so that doesn't seem like it'll work. Is there another way to disable 4g?
I've got the stock ROM running Entropy's latest DD kernel.
I've had this same exact issue while running Miui and the Siyah kernel. What I've narrowed it down to is likely to be some sort of power save mode that kicks in when the phone goes into deep sleep mode. I haven't had the issue since I've ran the Kernel cleaning scripts and reflashed the latest Siyah kernel, but it reappears occasionally. On certain releases of Siyah, I've ran SetCPU at a minimum of 200Mhz to keep the phone from going into deep sleep just so it wouldn't turn off the cell radio.
Also, as a side note, I've had this happen when my phone loses signal. After so much searching, it will turn off the entire cell radio and display "Emergency Calls Only" until Airplane mode is toggled.
I had this same problem even back with my Captivate. Hoping ICS won't have the same issue. I'm running CM7 and Siyah kernel.
I am having the same problem Data wont work until i turn airplane mode on and off
I am having the same problem Data wont work until i turn airplane mode on and off.
Have you found a resolution?
I like keeping my wifi on while my screen is asleep so that I can receive chat messages or e-mails without being at my computer. I never had this problem while running ICS on an unrooted TF201, but ever since I installed the upgrade to JB my wifi will always disconnect after the screen has been asleep for a few minutes. I've checked every setting I can think of. In the Wifi Advanced menu, I have it set so Wifi is always on, and in the ASUS customized setting I have Disconnect network during sleep to off. Under Power Saver I have Enable low battery settings off, set Low battery level to 0%, and even set Wifi OFF to off. Despite all of this, it seems like the tablet under JB goes into some sort of deep sleep and disconnects the wifi after about 5 minutes of inactivity.
I have noticed that this problem does not occur when the screen is on. I also have the dock, and set the screen to always on during meetings in the event that I don't need to enter any notes for a few minutes so I don't have to fool with any delays from screen wake .
Is there some setting I'm missing? Is it a hidden setting that I could access by rooting? Or am I dealing with something internal to the build that I can't change at all? This may not seem like a huge deal to most, but it has become one of my main uses for the tablet when I'm at home. I'm very disappointed with JB so far even though the wifi does feel more responsive on the Prime after the update (when it's not sleeping, of course!).
EDIT: I noticed this evening that the wifi turns off even when I'm running something that uses it while the screen is off. I was listening to Pandora, and about 5 minutes after the screen went off, my music stopped. When I turned the screen back on, I saw that the wifi had indeed become disconnected.
hey,
I have exactly the same problem with my tablet. I have checked every option, I did a factory reset several time, I have checked it on 2 different routers but it is still disconnecting the wife when it goes in the sleep modus. Did you or anyone else find a solution?
Hello, folks!
I have a rooted I9100 (Android 4.0.3 stock from Vivo, baseband I9100VILP3, kernel 3.0.15-I9100VJLP7-CL371396 [email protected] #3, compilation IML74K.VJLP7, CSC I9100UVILP3).
Sometimes I have problems turning on WiFi, it keeps always turning on and neither become active nor allow me to turn it off again. I then need to reboot phone to fix it (when it reboots, WiFi comes turned on and gets on normally).
Another problem I have with it is that sometimes (average of 4 - 5 times a day) phone loses registration with carrier. It completely loses* signal and shows a "prohibited" icon where signal strength is shown at status bar. (Edit) Sometimes it comes back again in a few seconds and sometimes it stays at that state, making me have to reboot it to fix the problem (turning on and off airplane mode doesn't work; in fact, with registration lost and trying to use airplane mode, it doesn't turn off and only fixes with reboot).
*Actually, it doesn't lose signal (can be seen in "settings - about phone - state" screen uploaded), but only unregisters from carrier.
(Edit: screen/phone language is Brazilian Portuguese)
I've downloaded another modem driver but never had time to test it.
I don't know if both problems can have the same cause, but both of them are very annoying (especially signal loss) and I'd like to make some tries to fix them, so if anyone knows what can I do (even data collection to investigate them), your help is very appreciated.
Thanks
Additional test (ServiceMode)
When I was in the forum to post this thread, I've noticed this other thread and I've decided to use ServiceMode code (*#0011#) to investigate further at the next time my cell lose signal. Unfortunately, it showed absolutely nothing. Literally nothing (just "ServiceMode" caption and no text on the screen below).
I just spent the time to post this because I know that, even if it has shown no information (on screen), maybe it still can be a clue for the cause of the problem.
Thanks
Pls help!
Does anyone have some light to shed on this case?
Please, I do really need to fix it, at least the signal loss problem.
Thanks.
Same Issue in the US on Tmobile
Mine started doing this just a day or two ago. Exact same issue. I can kind of operate on the EDGE network but 4G fails, only WiFi seems to work. T-mobile doesn't seem to have a fix for it.
Changed to MIUI
I've just changed to MIUI (reflashed modem also – now it is ZSLPE instead of previous VILP3).
I still have issues with carrier register loss, but until now it always reconnected after a few seconds. Maybe it is a carrier issue and not a phone one.
I don't turn on WiFi a lot, but all times I've tested it, it worked well.
Another thing I've noticed with this change is that battery temperature while charging used to reach 48°C (118°F) or even 50°C (122°F) while battery level was low (less than 50%), but now it stayed around 35°C (95°F), which is completely acceptable.
Hello experts,
I've been using my trusted S II for several years, when only half a year ago I rooted it and installed NeatROM on it (jellybean). Even before the rooting, probably after upgrading to the official jellybean, I was experiencing the following scenario:
I put the phone on airplane mode when I fly, or simply turn off both Wifi and Data (over 3g cellular network), so to reduce the battery consumption when I go to bed and don't want to be woken up by texts at 3am. I also turn off Sync option so that different apps (like gmail or calendar) won't wake up the device and try to connect to the internet every minute (and fail).
Then after a long period I turn on Data or wifi, and then - BOOM - a massive drain of the battery, which is accompanied by sluggishness in responses to me pressing the screen or even pulling down the status bar. It is as if all the apps that need an internet uplink - Facebook, Messenger, Whatsapp - wake up at once and try to get online together.
Does anyone else experiences this kind of effect? Is there a way to fix that?
Thanks in advance.
