Hey guys,
I have a "little" problem with my S2. Whenever I leave wifi on and let the screen go off, my phone will get into SoD (sleep of death) and I can't wake it up. This will happen sooner or later.
I have this problem with every ROM I can think of. It's been a long time since I used a stock ROM, so I don't know if this only happens on Custom-ROMs.
Finding out that wifi (or my data connection) was causing those problems was a long process with a lot of frustration and trial and error (catlog won't work or doesn't show anything regarding the problem).
I tried to get rid of this problem with the APP "PNF - Push Notification Fixer" by reducing the heartbeat intervall of the wifi and mobile to 5 and 6 minutes (15 and 28 before) this seemed to reduce the frequency of the SoDs, but they are still happening.
I can get rid of the problem almost all the times with deactivating wifi when I let the screen go off or lock the phone myself. I get the same result when I turn off "Wifi optimization" in advanced wifi setting, but this is draining my battery pretty fast.
So basically I can use my wifi only when the phone is on the charger (no deep sleep at all) or if I turn it off when I lock the phone (something like 30 seconds can sometimes be enough to get the phone into SoD).
With data on and the screen locked I only experienced one SoD and this seemed to happen when I lost my signal at all.
So my conclusion is, that whenever I lose my data connection (might it be wifi or mobile) my phone does seem to get stuck in deep sleep at that moment or the moment it tries to reestablish the connection (the problem most propably got less after using PNF, because my router would kick my phones connection after a few minutes (10 would be my guess) of inactivity and this prevented a long enough inactivity. But they still happen (SoDs)). When I turn both wifi and mobile off and let it go into deep sleep this is no problem and no SoDs happen.
The SoDs were less but also happened when I were on CM11 M11 official, but got really frequent when I switched to Markox89's version of CM.
This is no rant or anything, I just want to get to the core of this problem and wanted to see/ask if there is something different in the Wifi module or wifi settings in this build and what could cause this very annoying problem.
Maybe someone else has this problem, too. Maybe my hardware is just faulty and I have to live with this :/
If it wasn't for this problem this ROM would run pretty smooth and flawless.
Does anybody else have the same problem or somehow knows how to get rid of it? This would get a lot of frustration out of my everday life :victory:
My setup right now:
- Markox89's CM11 Mod (22.11) (4.4.4)
- Lanchon's TRIM Kernel for CM 22.11 (same problem before using TRIM)
- Lanchon's Music bug fix (same problem before using Music bug fix)
- Modem: XXMS4
EDIT:
- XPosed with Xprivacy
- common apps like Threema, Telegram, whatsapp...
Tl;dr: my phone gets stuck in deep-sleep (SoD) if I leave wifi on when my screen turns off. no problem with mobile on or both data connections off. Halp?
@xhoster try to clean flash a rom and try it without all those apps you are using and then you can see or its app related or rom related. If it's rom related then I think some people already posted before there.
Also maybe try a custom kernel.
Try these things, I can't help you further then this atm.
Also mybe logcat the issue so you can read where it goes wrong.
FINAL EDIT: The problem seems to be the wifi driver all along!
Flashed the Apolo Kernel and this solved my SOD problem only had two since then and those seemed to be APP related!
Happy right now
It's seems to be the xposed framework! Tried it with a fresh installation after RomNuke and the phone was sleeping for 45 minutes and nothing happened, installed xposed and 10 minutes later I got a SoD. Tried it with the 2.7 beta 1 and the 2.6.1 stable version. Both gave me a SoD when I left wifi on...
Is this a known problem or has anybody ever had this problem?
When I tried it, I didn't even installed any modules, just the framework.
EDIT: I am going to test a bit more to see if it really is xposed or just the phone hanging whenever a connection is lost.

So I'm rooted and have the latest/corrected 3.2 with pershoot's OC kernel...and nothing else. I noticed when I wake up my tab sometimes it will reconnect the WiFi sometimes it won't. Not sure why it's spotty. Before it used to reconnect almost instantaneously every time without fail. Is there a fix for this? Am I missing something?
I've got the same problem.
Nevertheless, the wifi code is store and don't ask for it
same problem
Ditto. I've resorted to just leaving it in the "always stay connected" mode even when the screen is off. Eats a bit more battery, but at least I don't have to toggle wifi every time I turn it on.
I've got the same problem on a brand new Tab 10.1N (special version for germany) WIFI edition. The tab came with Android 3.2 stock installed. First i thought it is my wlan ap which is causing the problem but it happens also on 2-3 other aps i've tried. I find this very annoying, especially on this high priced device... hopefully there will be a bugfix release soon.
So I did find out what the issue was for me. It was the Ad Free app. For some reason everytime I woke my Tab up, if the Ad Free message didn't come up neither did WiFi. When it did come up, WiFi would auto turn on again. So I removed this stupid thing and voila problem is resolved. Not sure if it'll work for others b/c like I said I'm rooted and Ad Free is a rooted app. Good luck though!

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 have noticed in the last few days that my new HTC One is not waking from sleep with WIFI functionality. When it wakes, the WIFI symbol in the notifications tray is gone. When I go to settings, And look at the WIFI option, It says that it is disconnected. When I touch to configure the WIFI settings, the settings app hangs on a black screen. I have to reboot my phone to get the WIFI back. Is anyone else having this issue?
Phone Model: HTC One
Router Model: ASUS RT-N66R / RT-N66U
Frequency: 5ghz
I am now testing in the 2.4ghz frequency and will report back my findings.
I can confirm that I don't experience this issue with 2.4ghz. No drops in 4 days. When I switched back to 5ghz on the 5th day, I got the drop and freeze within the hour.
Sent from my HTC One using xda app-developers app
I'm having the same issue. Can't tell what frequency band it's on when it happens though sorry.
I am having the exact same issue. It coincided with installation of an app called mute-o-matic in my case. I was wondering if the crash is related to the installation of this app. Could any one experiencing this crash comment on this?
[Update] It has happened 3 times in the last week. Wifi function just locked up, and had to restart phone to fix. Very frustrating. It's reasons like this that is driving me back to iOS. All the amount of tweaks and customization is not worth it when the phone is not reliable on basic functions. iPhones may be boring, but it at least I never once ever in years on owning them needed to restart it to fix a problem.
[Update 2] Android 4.3 update seemed to have solved the wifi crash issue. It is running much more stable after the update. Had it installed for 3 days now, and no crashes or self-rebooting so far.
Cleaning
Thread has been cleaned. Please be respectful to others and do not incite.
[Update 3]
I previously thought that JB 4.3 update has rectified the wifi crash issue for good. After over a week with 4.3, wifi crash happened today.
The wifi option page was not grey-out, but it would not connect to any network, When I toggled it from "on" to "off" state, it failed to respond. At the end, only a phone reboot could fix it.
Frustrating to say the least.
[Update 4]
I can now reproduce the wifi problem when leaving the phone running on battery overnight. During the first week after 4.3 update, I left my phone plugged-in to power most of the time, and perhaps as a result, the wifi crash did not happen.
Basically, the wifi crash I am experiencing after 4.3 update is more or less the same issue reported by others on their HTC Ones (including One, One X, One S), where the wifi failed to connect after long period of inactivity.

For now, I am going to switch "Keep Wi-Fi on during sleep" to "Always", as suggested in the 2nd link above. This should keep the wifi connection on the during sleep, and hopefully fixes the issue. I'll report back.
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.
