Please tell me I'm not the only one with this issue!
For the past three weeks, I can't send/receive texts or even calls sometimes while WiFi is turned on. However, when I'm out and not connected to WiFi, there is no issue. I've tried calling T-Mobile but all they wanted to do was factory reset my phone. When I DO get phone calls, the other people seem as though they are breaking up and I can't understand them AT ALL. And when I do manage to send texts, they take forever to reach their destinations.
Anyone else experiencing this?

thanks for the answer! I used to have adblockplus but I uninstalleunit and did a factory reset and the problem still persists. I tried the other solution also and it worked for a good five minutes and now back to square one...
It's getting really annoying because I feel as though TMobile didn't really know what was going on either.

well since last night my daughters phone would receive phone calls but she couldn't call out everything else was working call t-mobile again had phone off had them re send signal to sim. working now but this is what bothers me now he said that it seems from time to time the sim card would disconnect from the phone and we should get in the habit of turning the phone off and then back on to fix this issue.i wouldn't tell a customer that just bought the phone 2 month ago that kind of respond especially when you are buying a $600.00+ for this phone.
What type of WiFi do you use?
I use WiFi calling on mine frequently and don't have any problems.
For the sms, are you using hangouts for texting?

Just your average home WiFi connection if that's what you're asking.. I saw that WiFi calling was causing the problem for some people so it's been turned off on my phone for a while.
And I used to use hangouts but I switched back to regular messaging.... Then a few weeks later, this problem!

Some people reported same type of issues when they had"smart network switch" on. Disable that if it's on and see if that fixes the problem.

Hi
Since last update (9 dic) everytime I restart the phone I can see the 3G icon on the systembar but the 3G data connection is off on settings.
I have to set the 3g data connection on and then off to make the 3G icon disappear.
With the 3G setting off I reboot the phone and the 3g icon is back again ...
Any one is having the same problem ?
Thanks Iosu
How did you turn off 3G? Did you just turn off "Data Connection".
I am trying to figure how to do it on me AT&T HTC Titan.

yes I turn off data connection
I think your issue is different
Hello Iosub,
The 3g icon could be just indicating that you are using the 3g voice ( not the data). On my old Nokia's they would show the 3g icon even though I never used data.
Hello nemets,
Unfortunately not all the carriers allow the 3G connection setting in their Cellular setting. Though the option does exist as evidenced by the How-to Cellular settings page on the Microsoft website.

thanks for your answer.
i don't think that is the issue.
1. Because when i go to settings the data connection is off
2. Because if I turn on and the off the data connection the icon disappears
3. Because this was not happening with firmware 1.08 this is new with version 2.1
i think is a bug with the new firmware , lets see if someelse has the same problem..
Thank you
found a fix
I have found a fix.
I have turn on flight mode and reboot.
then I have turn off flight mode and reboot
I have reboot 5 times and no more 3g icon on startup. Only if I have the data connection on prior reboot witch is the correct behavior
hope is no back again
Iosu
I've noticed strange behavior with 3G (H) indicator.
Sometimes the icon appears even with Data Cellular off, I also see that restart behavior.
Will try the Air Plane mode trick and see if it solves this ODD thing.
What I don't understand is: why in the H**** this is done by firmware? Shouldn't this be controlled by the OS?
PS: when Cellular Data is OFF, even if the icon is in the screen, there is no connection working.

I was having the same issue.. After my trick it has been fixed.. try it
also. now my batery live is longer
Iosu
I also noticed this bug, once yesterday and twice again today.
However, I couldn't identify what triggers the issue, it seems to be happening out of the blue on my phone.
At first I thought I've fixed it by turning cellular data on/off but that proved to be only a temporary fix (as it occured again).
I also agree the issue has an impact over battery life. Usually my battery drains very slowly overnight (~2%) but last night it drained 10%. I examined the Battery Status graph and it clearly showed the battery drain going down abruptly around 5 o'clock.
I will try the airplane mode fix and report back.
UPDATE
I tried it but didn't work, maybe I didn't do it right:
- turn cellular data ON
- turn flight mode ON
- reboot
- turn flight mode OFF
- reboot
- turn cellular data OFF
After a few hours, the H icon appeared all of a sudden on the status bar...
the issue is back
Now the trick does not work :-(
Time to find a way to fix it
HTC response is to reset.. Why in the hell they always give the same answer ?
Iosu
Hello,
My Titan has this problem too.
I have made the "Airplane" solution but since yesterday the 3G icon appeared again.
Any solution for this or should I reset the phone?
Thanks

Another Trick
Hi
I have found another trick.
step to fix
1.- Set DataConnection ON
2.- Go to a place where you lost the antena coverage connection completly, example a garage
3.- Go to DataConection turn OFF
Now move to a place with Antenna coverage
you will see that there is no more 3g/h simbol.
Hope this helps
Hi to all,
Unfortunately I ve got the same annoying problem after the last update through Zune. Hope this trick works,but maybe a permanent solution is another HTC update to correct this bug...
The above trick worked for almost 24 hours,now the bug appeared again. Thanks for your help anyway. One question please : what if I hard reset the phone? That means no more updating through Zune? Thanks in advance and Merry Christmas!

I guess that hard reset may be the solution since the bug came up after the last update.

So sometimes when I'm connected trough wifi my whatsapp won't send or receive messages. I then have to turn off my wifi , receive/send all messages and turn on wifi before it will work again. Does anyone have an idea?..

WHAT firmware and what version of whatsapp are you using?
Is your wifi kicking out a good signal?

I have the exact same thing, no matter what Rom, firmware, kernel, version of Whatsapp, router, modem, whatsoever. It sometimes just happens, no idea why.
When this happens I have a good signal. I'm on 2.3.6, and have the latest whatsapp version.

What did the Whatsapp developers say when you contacted them?
yeah these issues still exist... got it now on my device.
got I9100 on latest cm10 nightly (8th Sept.) with latest whatsapp version. and if you read all comments on the market you'll see that many ppl got these problems. sad
same issue here with i9300 stock ics
it works only on mobile data and when i turn the wifi on Whatsapp doesn't work
tired of deleting and reinstalling but same issue !!!
BTW my device is not rooted ..
i have been using what's app for good 4-5 months now and today i just got this issue. whats app won't work on wifi unless i turn it off and turn 4g on. i tried uninstalling and deleting the folder and did a clean install. it still won't work.
Just hit me last night
Got the same prob since last night!!!
tired to uninstall and reinstall it + boot my device million times and still won't work over wifi but my damn slow edge network!!
i have sent a email to whatsapp costumer's service and still waiting for their reply
These are issues related to the whatsapp Servers or sth. For me it works again. Without reinstall and so on. Just wait ... and tell them bout the problems
I've had this same problem for at least 6 months... doesn't work on WiFi but is fine on data...
What seems to happen is when you turn on WiFi it works fine for a while... but then stops getting or sending messages completely... just sometimes randomly it may start working again... say if you have lots of messages backed up to receive... at times it may start working again... but that means asking you people to bombard you with messages and still its not a sure shot solution...
Quite annoying I must say... especially considering reception is really bad in lots of areas and WiFi is the only way...
WIFI Whatsapp
Sort of same problem here, when i am on wifi and whatsapp and my phone is on there is no problem receive and send.
But when the phone is on standby after 10 to 15 min no more messages receiving, wifi is on.
when i turn the phone on and open whatsapp the messages pop in....
On data without wifi no problem.
WIFI setting always on.
Same problem buy not consistent. I have found a kind of fix, if your rom supports it, I use the long press back to force close function, then restart usually solves it. Alternately, pressing home, then swiping it off the task switcher sometimes helps too. Sometimes all you have to do is wait it out.
Was this problem solved in any of the updates. It appears as though I'm having this problem on one of my phones. It's the stock ROM with great wifi signal.
EDIT: I realize this is the S2 forum and my problem is an the optimus, but I am inclined to believe this is a whatsapp problem

The same problem started happening in the past couple of days. I a using CM 9.1. I enabled the Kill Application on long press of back button and you're right--After I did that and launched WhatsApp, the waiting messages (with the clock icon) went through and I got a check mark, then two.
Weird. All the other apps are working fine with Wi-Fi.

I travel a lot and i was in India Last week and this week i am back in germany and it suddenly stopped working on saturday.
Any Solutions would be really appreciated.
Try this! Worked for me !!
I used VPN which worked for me . But i wanted a permanent solution. So I upgraded the modem firmware. Now it is working fine
Sorry to post here, but Im facing the same problem on my galaxy s5. I've tried a lot of things and nothing seems to fix it. I've changed my wifi router and the problem persists.
anyone came with a solution?
The problem is on the wifi router. I changue my router two days ago and i hadnt no problem with the old one.
If you retry to download pictures, it gonna works, but its really slow. Try to changue your wifi router to a newone
***********SOLUTION*****************
Guys,
I have also faced the same problem and here is the solution:
There is a Problem which started on 10th November. BSNL has blocked whatsapp.. BSNL users can not use whatsapp through wifi or dongle.
But there is a solution for this.. :
Install " vpn one click" or "Easy Surf VPN" app
Connect to India server
Or any country
Once ur done with this, u can use whatsapp and all the other sites blocked by BSNL
Enjoy Whatsapping

Hi guys. Im one of the developers of Root Call Blocker and a number of other apps using a custom build root telephony layer. There have been recent reports of our apps behaving badly with the new official JB updates.
We need people to check whether this is true - especially people with CDMA devices which we have no access to. Either way, please download the free versions of the apps in question (look at bottom of post for links) and perform some simple tests:
- call yourself from blocked numbers
- text yourself from blocked numbers
- mms yourself from blocked numbers (CM/Delta only)
If something seems to be working fine, please try again just in case. If you have problems, go to Settings and find the "Write to us" item. Once you click on it, be sure to mention in the description field that youre from xda - just put XDA TEST or something.
If you can, please try to include the number that was supposed to be blocked - the logs consist of thousands of lines, so that will help a lot.
Root Call Blocker - https://play.google.com/store/apps/details?id=fahrbot.apps.rootcallblocker.beta
(trial allows one item, you can use groups to block more)
Call Master - https://play.google.com/store/apps/details?id=fahrbot.apps.blacklist
(this one is completely free)
Thanks in advance. Also, you can write about problems here if you like!
Hi,
I just tried your application in Trial Mode.
I added a phone number in the blacklist.
I enabled filter mode (SuperSu asked authorization, accepted) : In parameter -> "Activer le blockage des appels"
and I suddently lost network connexion... Unable to reactivate it, i had to reboot the phone.
Tried it again, and same result, I loose network signal when I enable blocking...
Edit : I tried the debug option to restart service, but if blocking is still enabled, the signal is lost again directly. If I disable blocking before restart service, it seems to restore signal
Hmm. How long did you wait after root was granted? Sometimes it can take a few minutes so please just check again to be sure. Also, logs through the app would be very helpful, as described above,
Sent from my Nexus 10 using XDA Premium HD app
Well I tried a few times, waited one minute, no network signal. Even with a restart service, the signal came back for less than 1 second and desappeared again.
I disabled blocking, restarted service, and then the signal was back.
I sent 3 mails with logs with the application report tool, all with title : XDA TEST (1/2/3) : ....

If youre the one who sent logs, i can see that you waited 10(!) seconds. Then you just kept pressing restart. The radio layer cannot possibly reboot in 10 seconds.
Please, wait at least 2 minutes.
On the Test 3 i waited approx 1 minute I think
I can try again. It will be XDA TEST 4
---------- Post added at 12:46 PM ---------- Previous post was at 12:32 PM ----------
So I did the following :
Enabled call blocking : network signal lost
Waited 3 minutes and tried "redémarrage du dispositif" : Nothing happened
Waited 3 minutes and tried "Redémarrer le service de téléphonie" : Network signal came back for 1 second and lost it.
Waited 3 minutes, disabled call blocking : Nothing appened
Waited 3 minutes and tried "Redémarrer le service de téléphonie" : Network signal came back and stayed ON, H+ appeared. (call blocking disabled 3 minutes before)
Used the "Nous écrire" menu to send the logs
It is EXACTLY what i did right now, I just moved the screen with my finger during the operation to keep screen ON, nothing more.

OK im getting my phone today, so hopefully a fix will be coming in the next few days
OK guys, issue fixed, so thread is closed. Thanks to all.
After some experimentation I narrowed this down to a conflict with Bluetooth headset use and wifi data on my DNA. It's not related to the channel wifi is using as I've changed the channel my router was using. The data connection stops about 20 seconds into a call comes back as soon as the headset is turned off. Weird. I'm going to call HTC tomorrow to see if this is a problem with my device or if it's a problem with the DNA.
If anyone can try this on their device it would be helpful to know if they have the same issue.
"While I'm on a call I cannot browse on my wifi connection. For the first minute or so of a call I can browse but then I can't connect to sites until after I disconnect from the call. As soon as I disconnect from the call I get the data back and all is well. I have restarted the phone and tried again and have the same problem. I know about the issue of not doing voice and data when on 3g on the DNA, but can't imagine that I should not be able to have a wifi data working while on a call. A very small page like the Google main page will connect, but a larger page will not. I got the DNA as a replacement for my Rezound and was aware that it would not do voice and data over 3G but this problem with wifi browsing when on a call has to be an anomaly. Right?
BTW, I'm stock (unlock no root or ROM) and have taken the OTA.
Anyone have this issue or some advice on what the problem might be?"
Your best bet might be to backup your current Stock setup and flash a rom with a custom kernel such as Viper to see if it makes a difference.
(If you're unlocked as the post suggests)
I have only had to use Google Maps / Search in-call a few times when I had my Rezound so I can't really say anything in particular.
if appears to say not unlocked rooted or have a custom rom which suggests your sol until either htc sends a ota fix or the devs can get the new ota unlocked

did not mean for it to sound s*****
So, over the past couple of weeks, my phone just randomly loses the ability to use data. I use that term because, 4G is still on the phone, i'm not getting a no service signal, I just can't do anything that would use data. I'll be at work, using the Wi-Fi, then i'll leave and all of the sudden, nothing. It's like my phone just loses signal, but doesn't tell me it is. The little arrows under the 4G symbol don't do blink, nothing happens. I end up having to restart my phone. I haven't done anything different for this to happen. No updates, i'm not in abnormal areas when it happens(even if I was, it comes back after restart), nothing. Anyone have any insight on this?
I've had the same issue for about a month now. I am rooted and used this method
http://forum.xda-developers.com/gal...-to-update-to-i545oc1-5-0-1-keeproot-t3096558
if i reboot i get my signal back, or sometimes if i toggle airplane mode on/off it will come back. haven't been able to find any fixes on it yet though...
I have the same issue, I've found toggling airplane mode works 90% of the time.
Sent from my SCH-I545 using XDA Free mobile app
If u go to > Settings>Wi-Fi and tap the hardware menu button (bottom left most button), tap advanced...see if Smart Network Switch is "checked". If so, try toggling.
This is the worst bug yet!
I hope someone finds a fix to this soon. I am running 5.0.1 on a Verizon S4. All the techs at the Verizon store could tell me is that I need to upgrade to a new phone. After telling them I didn't want a new phone right now they gave me a new SIM card but that hasn't helped either. When I go into an area where I don't get service it seems like my phone just stops searching (perhaps to save battery?) Then it never seems to wake up and find service again even after I go back to a known 4G location. The toggle airplane mode on and off thing rarely ever works, so I don't think the radio is just "sleeping" to save battery. A complete restart is the only thing that helps.

I have this same issue (stanglite 5.01 ROM) and have tried a number of things to resolve it. I can post those steps if it is helpful to the discussion. In short, I've tried several modems and resets.
I should specify that mine is not identical to the OP as mine specifically shows that I have no signal. and it doesn't seem to be trying to find signal.

Not sure if it's just me or not, but ever since the update, my antenna seems weaker. I've never gotten much service at my house, but typically, I could go near a window, or outside and get service. Now, once it goes so long without service, the only way to get it back is to restart my phone. I've tested this even going into areas where I know there's good service. I've tried toggling airplane mode on and off, and even that doesn't get it to hook back up. It's incredibly annoying having a phone I pay this much for, and yet, can't use it without restarting every time I want to make a call or text.

One of the responses from this or another thread on this subject mentions to try changing "Preferred Network Mode" to LTE/CDMA. I did this and then rebooted (didn't work until after the reboot). It seems to have corrected my issue (I did also uninstall some apps I don't rely on but otherwise no other changes). Note that after another reboot the mode seems to have switched back to Global, but the issue has not returned.
Change "Preferred Network Mode" from Settings > More networks > Mobile Networks > Network mode.

There are tons of hits on this issue but no solutions...
It would be nice to find the actual problem instead of throwing a bunch of things at it to see what sticks.
