I switched to e4gT from evo 4g.. loved the phone at first.. but now getting very annoyed by it..
in fact.. it's a great little computer .. but basically all the phone functions don't work consistently for me.. and internet browsing is good.. but hindered by the slow network speed.. (even with wimax)
GPS... sometimes lock quickly.. sometimes it takes minutes.. using the phone as a golf gps is a joke now because it's never accurate enough... my evo 4g was much better... and yes.. that's after i use gps tools to reset.. update gps.conf via root explorer .. etc etc.. and no.. rebooting everytime is really NOT a solution
Bluetooth... i paired it with my car... and when i get into the car.. it's shown as connected to my car.. and music actually streams to my car audio.. which is cool.. but somehow.. sometimes voice call will NOT get directed to my car's audio... and bluetooth button on the dialer will be greyed out... not sure if anyone else is having the issue ... when that happened.. voice call get NO sound at all.. not from car, not from the headset... as bluetooth is greyed out on dialpad.. i would have to basically disable bluetooth from settings to actually talk
WIFI... every now and then... it will lose connection to my home wifi... a recycle of the wifi will fix the issue.. i never have any problem with my evo 4g.. and even right now.. my other device (iphone 4, ipad) all stay connected.. so i am sure it's not my router.. it's annoying.... and this happens even when my phone is near the router... and almost always happens when the phone wakes from asleep
i kept checking forums every day for solution.. and tried many solutions.. but it's still not working consistently... i am curious because I don't see that many complains from other users..
i am rooted on caulkin's rom with rouge stock EL13 kernel / modem
Bluetooth works well.wifi signal goes up and down.but, stays connected.
Gps for me is an issue.sometimes it takes forever to lock on.and when it does
it doesn't stay connected a lot.coming from an evo.my old evo locked on instantly and stayed
connected, even when it was cloudy.disappointing
EL26 did a lot of changing in GPS files i hear. Check it out! and i havent noticed wifi or bluetooth issues
For the Wifi go to Settings-Wireless and Networks- Wifi Settings-Click the menu key-Advanced-Wifi Sleep Policy should be NEVER.
By default it's set up as when the phone goes to sleep.

If you are experiencing those gps issues something is wrong with the phone. I had the same problem and tried every "fix" nothing worked. Went in to sprint and they exchanged my phone..gps works perfect on the new one

This started happening to me couple days ago. My phone is connected to wifi at home, and whenever I want to use my phone after its been in idle, everything looks normal. The wifi signal is there, but there is no data, I cannot check email, browse internet, anything with data. Only way to fix it is to reboot or turn wifi off and then back on. Everything is fine when I'm on 3g, there are none of these issues. I am on Calk 2.7 (not 2.8) with the latest kernal, EL28 (I think thats the latest).
If I have an app running in the back that is constantly using data (google music) (recall, ONLY on wifi, NOT 3G), the app stops working whenever the phone goes into idle, I guess. Basically leaving a data consuming app ruining in the background did not help the issue.
I have tried searching, and some other people have experienced the issue on different devices (NOT epic touch), but no threads offer any solution(s).
Any help would be greatly appreciated.

I had this issue on my previous epic touch and I took it back and exchanged for another one and the one I have now doesn't do it. It had the same problem u describe. Might want to check your router first though since it just started. Mine always did it and it did it on other Wifi networks. Good luck.

I've seen this happen on four different E4GTs. It seems random and only occasional. I've seen it on EG30 and EK02 stock, I haven't tried other "modems" or roms yet. I'm not sure what causes it, but a quick wifi toggle seems to fix it. Seems like the wifi radio just sort of "freezes. " Wifi sleep policy set to never, doesn't seem to make a difference. Minor annoyance.

What baseband are your running? Have you tired another baseband?
I didn't think the modem has anything to do with wifi. I have this issue on certain wifi networks I use. I have made tweaks to see if it is security settings or what but haven't figured out a pattern yet. I use a wifi widget and it looks like DHCP hangs up cuz it won't give it an IP. I reboot the wifi router and it works right after evertime. I will sometimes powercycle wifi on the phone and it will work. I really think it is a wifi router setting for the network but not sure which yet.
Really odd problem here - as of a couple days ago, everything was working perfectly with my galaxy nexus. I decided to jump over to CM10 (was on codename android, IIRC), right after I think there were some new commits to AOSP.
From here on out, my phone would never enter deep sleep when connected to wifi. Any wifi hotspot - the ones I've been using, a hotspot I created from my desktop - the icon would show the phone constant receiving data via wifi. Using better battery stats, over about 5 hours on my desk, 4.5hrs were spent with a WLAN_RX_WAKE kernel wakelock with my phone sitting at 350MHz instead of deep sleep for that time.
I tried a bunch of different kernels (stock CM10, franco, imoseyon, etc) both new and old versions, but the problem was still there. I tried clean flashing a rom, and only installing better battery stats. Same thing with all kernels.
Factory restored google stock images to BOTH ICS and JB. I still have the problem. Tried disabling google location services. No dice. Tried a couple basebands, but I'm pretty sure that only affects cell/data performance, right?
I honestly have no idea what is going on. I've been on this hotspot (campus wifi) for months now without a problem, and now this. Some threads say that this is caused by DHCP requests from the router, but why would I have not seen this until now? My idle drain was at about 1-2% per hour before this, now it is close to 10-15%.

This is literally the EXACT SAME problem I'm having...I wish someone could properly explain why this is happening and how to fix it.

Not sure if you've tried this and it helps but maybe you can try Network Log or Shark from the store to diagnose this?
Network Log doesn't show up with anything, so the wakelock shouldn't be caused by a rogue app.
Shark, on the other hand, after about 10 seconds of logging, netted me about 300 DHCPv6 'solicit XID' requests. There a bunch of different sources from these requests, they just seem to be other devices on the network pinging my phone to see if it's a DHCPv6 server...?
I've seen some suggestions on other forums to mess around with the router settings, which I can't do because it's campus internet.
Since you've tinkered with rom/kernels etc on phone without any seeming change, it's feasible that there's been some change recently on the other side of the equation namely the network settings of your campus wifi? Maybe your University's tech department has implemented something new etc? Have you tried asking others with wifi enabled phones if they are experiencing this as well?
Found this here (pretty sure you've come across this if you've been googling abt this issue but posting anyways)
"Another more elaborate solution if you rely on that network a lot, is to purchase a wireless bridge or gaming adapter and connect it to your apartment wifi and then connect your own wifi router to that. Then the gaming adapter would get the dhcp IP from your apartment (so who cares if it is renewing it constantly) and your router would treat the connection just as if you were connected directly to an internet connection. Then configure your router for static IP addresses or if your router does not cause issues with DHCP then you don't need static IPs."
from http://rootzwiki.com/topic/16134-kernel-wakelock-wlan-rx-wake/
I know I had an issue with some wlan rx wakelock thing last year but I cannot for the life of me remember how I got rid of it or what changed
Hmm, seems like an okay solution but my friend's devices don't seem to show the same symptom, and since I roam campus alot, a wifi extender wouldn't be ideal.
Bump. Any other ideas?

I am seriously ripping my hair out from this goddamn wakelock ****.
I wake up at 9am and have to charge my phone by 4pm because it's at 16% with 40 minutes of screen on time. Seriously? This is a JOKE.
I've checked with BetterBatteryStats and CPU Spy. Both confirm the phone keeps sitting at 350MHz when it's supposed to be sleeping, as well as wlan_rx_wake keeping the phone awake.
I've set my phone to receive a static IP from my router (DIR-655) but it doesn't help. I really don't know WHAT to do. I've downloaded shark to my phone, sniffed packets, but haven't been able to get anything useful out of it since there is a LOT to sift through (unless you know what you're looking for - which I don't).
This is by far the worst bug/issue I have ever encountered with my phone and it is seriously getting on my nerves. I will be forever greatful to anyone who can help me pinpoint the issue and make it stop.
Also, i REFUSE to "go buy a new router" as it's bull****. This is a bug people experience only sometimes it seems and NO ONE has a fix for it. I read somewhere about a fix being implemented in some kernels but they were for other phones, never found anything like it for the GNex. If anyone knows anything about a fix like that, please show me the way.
I already checked for rogue apps, there were none keeping wifi awake. I've even tried with a totally stock, newly flashed phone with stock kernel and everything. NO extra apps installed except shark, CPU spy and betterbatterystats sideloaded. I didn't even input my GMail to stop the syncing. It STILL KEPT MY GODDAMN PHONE AWAKE.
I am SERIOUSLY desperate. Considering just selling my phone and opting for something else if this continues, it totally cripples everything.
/rant over
turn on WiFi, Bluetooth, and GPS, for about 30seconds, then turn them off. put your phone to sleep, then check if you're going into deep sleep. CPU spy is a good app to check if your hitting deep sleep.
Change wireless network encryption? Wpa2, tkip+aes, aes only, tkip only? Wpa?
Change wifi channel?
Edit: scratch that. Try disabling 5ghz band.

I had a similar issue, it turned out it was Dropbox LANSync in my home LAN. I used an experimental forum build on my PC, so it could be this, but in the end I turned LANSync off, since Android doesn't make use of it anyway.
So try this if you have Dropbox running on your network clients.

5GHz band? Where do I disable this, the phone or the router? My router chooses channel automatically and is set to Auto 20MHz/40MHz channel width.

A quick update, I just tried all the suggestions in the quotes in my previous post but to no avail, still getting the wake locks. I'm seriously going crazy.
Turning wifi off did let the phone sleep, but that was expected as the wake lock is related to wifi. Nothing else has worked. NOTHING.

This issue appeared again for me, it obviously also helps to disable the NETBIOS on your Windows PC network adapter. There are guides for that online. Also get the "Network Log" app in the Play Store, it shows the traffic so you can see which one's are for the kernel (wlan_rx_wake is a kernel wakelock).
Also uPNP feature in router can cause all kind of weird behavior. Better block it from router's firewall.
Sent from my slimbeaned GNex
What baffles me the most is that all of this shouldn't be needed. I shouldn't have to disable netbios and do things to OTHER devices just so my phone sleeps. This is a jellybean issue imo, I never had these problems on ICS.
The experiments continue, updates incoming.

I also suspect the major issue was that my wifi channel was the same as the ones around me. When I changed it, the wlan wakelocks went down significantly.

5 Ghz band is disabled when you enter Wi - Fi - advanced - Wi - Fi frequency band ... It's set to auto by default, you try either 2.4 or 5 ghz on manual and check if that helps ( incase you didnt already )
Does anyone have any news about this issue? I have the same problem and I can't find the solution. I made several test without any good results.

Hello,
I am running into an issue where I will lose connection after coming off wifi and it seems 4G/3G is not picking up. I must either reboot my phone or toggle airplane mode to regain signal. I've been searching around and I don't think I've found any thread similar...or it's hard for me to pin one down using search terms.
I'm running paranoid 2.16 and lean kernel. Gonna try and flash a radio and see if that helps...but if anybody can point me in the right direction or suggest a few things, I would greatly appreciate it.
Thanks in advance!
Lte or gsm version? Apparently the lte version has reception issues in general.
I used to take the subway to work. When coming out of the train, after losing service while underground, I would on rare occasion have no service while above ground in an area where coverage existed.
This bug existed on every Samsung smartphone I've ever owned (sch-r720 admire, t989 Hercules, and yes the i9250). I'm convinced it must be an android bug.

I'm stock (rooted)/GSM and I'm having this issue since 4.1.2. 4.1.1 was very stable for me. Today it lost it's connection completely to T-Mobile twice, where the status was always connecting even though I had 3 or 4 bars. Additionally, airplane mode would not engage (no symbol in menu) and could not be unselected from the power menu. Only way to fix it for me was to reboot the phone.
Additionally, I received a call today and the phone froze. I could interact with it barely, but couldn't switch apps or get out of the completely black phone screen. I had to unlock the phone to even see anything. After I missed the call, which rang for a long time (still no idea who it was - no logs and T-Mobile only lists connected calls), the screen would not come back on and I had to do a battery pull.
I'm about ready to just say F*** it and reinstall 4.1.1 stock back on this thing. I want my old phone back
Additional notes: The phone is encrypted due to my job requirements.
If restoring your backup cures the issues, then its baseband/radio/rom related. If not, the phone is damaged.
I had an sgs2 t989 which one day decided to lose its data connection. It constantly tried to sync and couldn't. Voice and text worked, but it couldn't get data (even edge). Changing roms didnt fix the issue and I had to exchange it in store.

Freaking annoying.. always seems to happen when at the worst times..
I also had this behavior on my old i9020t nexus s to be honest..
Both my data and WiFi have been acting very strange the past week. Both services will show me as connected but I will only get the upload arrow showing on each indicator and then sometimes the icons just go gray. It has been happening very often and I have changed both my ROM and kernel on clean installs and I still have the same issue. Any help would be appreciated.

I started a thread here on a topic where my wifi and signal bars turn gray and the phone doesn't have data connectivity any more. sometimes this happens a dozen or more times a day and sometimes once or twice.
one response in that thread indicated that 4.2.2 made a positive impact on the problem.
I've been searching for a definite fix for this data/WiFi issue to no avail. I'm not entirely sure of when this issue began to occur but my phone (Toroplus) constantly loses WiFi signal. By losing signal I mean WiFi will turn off and on all by itself. And yes, WiFi sleep policy is set to stay on always. This issue alone made me go back to stock only to find the WiFi issue is present there too. I've also ruled out my router as the culprit. Im suspecting this is a Google issue. By the way, I talked to a sprint store employee who owned a galaxy nexus and after a few minutes of playing with his phone, which was completely stock and never rooted, I noticed his WiFi connection would turn off and on all by itself too. Any insight from anyone with knowledge to this would be appreciated.
Wi-Fi optimization off. If that does not fix it, I dunno.

Thanks for the suggestion but that doesn't fix it. Are you not having this issue? What's your setup? What ROM do you use? I've basically used all of them and it never goes away. I'm thinking of going to the HTC One when it's released just in case it's a Samsung issue.
I have also experienced this problem, especially at work where the network uses some WPA Enterprise variant. I've digged through logcats and can't find the problem either. A few Google Code forum posts talk about a possible bug introduced by network adapter manufacturers, or wpa_supplicant configuration issues. Haven't found a workaround yet, so I had to go back to 4.1.2, which seems to be stable.

The more I read on this subject the more I come to realize this is not specific to a certain device. The only common denominator that jumps out at me is jellybean. Seems like the issue is with Google, not hardware. Sucks that such a basic feature is not reliable out of the box. At least now I can understand why my buddy calls Android "buggy". Hopefully this is fixed sometime in the near future.
