Phone activity cancelling Active Sync

Can anyone help me find out how to set active sync not to be cancelled when in coming call is recieved or set phone not to cancel active sync when synching?

Could it be, that you have disabled 3g?

I wish it was that simple. I don't have 3G but I have read that it is because when you pick up the phone and the screen goes blank which automatically disconnects active sync.
It just doesn't make sense to me to have the phone connected to USB and charging yet unable to continously synch data and use the phone.

Having the same issue. Pity because I keep my phone connected in the office on a long cable, Phone constantly ringing and hence disconnecting...

Yeah, I have the same problem. I deal with it by just forwarding my mobile number to my direct line.

I can't imagine that the screen going blank has something to do with it. The phone goes into standby state but activesync is still running in the background - which I know for sure because sometimes I receive pushed emails while I'm having a call.
I still think it's having something to do with 2g/3g. At least my experience in Austria was that way. As long as I was using 2g it was not possible having a data connection and a voice connection simultaneously. Only with 3g that was possible.

If that was the case then my previous TyTN II should have had the same problem. Without 3G, my TyTN II synced without a problem when calls are received.

Right - in this case it must have a difference cause! Sorry I don't have another idea.

Wifi/Wifi Calling/Airplane mode/MMS weirdness

Ok. This is very strange. It's happening on both of my One S phones. It's possible it only started after the OTA update.
When wifi is on and wifi calling is enabled, the airplane mode setting goes into a state where it says it's "turning off" and the on/off button is diabled.
When it's like that, I can not send MMS with Go SMS (I can send with stock messenger during that time).
If I turn wifi calling off, airplane mode goes into off and I can send MMS with Go SMS.
I know the OTA had something to do with a wifi calling fix, but I think they broke something.
It's like when wifi calling is on, it's disabling the ability for mobile data to come on to perform functions that are not done over wifi (i.e. MMS).

How do u activate WiFi calling? Sorry I'm not stealing your thread and is it true if using WiFi calling u don't use your minutes?

It's in the settings menu, I don't have the phone at the moment, but I think you have to click the dotted line under mobile network and it's in there. Yes, wifi calling is free, but you have to call them and add a free wifi calling plan to your account.
Any further discussion, I'd ask that you start your own thread.
Anyone able to confirm my findings on the issue I posted about and any thoughts as to what's going on?

I cannot exactly verify what you are experiencing, but I use GoSMS and I have always had trouble with it and wifi. But I do think it had gotten worse since the update.
In my situation when I boot the phone art home (where I have no signal and a fixed, auto wifi connection), wifi calling isn't on... Until I make a call. Then it takes about a minute to turn on and turn blue (it almost always starts out with an "invalid SIM" error). And in my situation, until wifi calling is running, my SMS is spotty. Them while it is initially on I can also send SMS. Then when it goes off again (usually if I don't make a call for about 30), at this point I cannot send SMS without a reboot.
I am running various log applications, and in reading the log enough times, I can definitely see consistent regular errors mentioning the GoSMS app. I also am pretty sure this update fixed a few things, but it also broke stole things.
You should go download a log program, and let me know of you see GoSMS errors.

That's for comfirming!
How'd the screw this up so badly? It's going to be months before they push a new firmware up to fix this.

Same here

So any work arounds to get MMS to work with Go SMS w/o turning off wifi calling?
Also, I posted on the T-Mobile forums here:
http://support.t-mobile.com/message/148722
Maybe some of you can jump in here and voice your complaints too?

I was able to get HTC to escalate to a tier 2 tech who was very vigilant with trying to reach me to discuss the issue.
After detailing exactly what's happening, he commented that he say some other reports of this issue and something about a youtube video detailing it as well. Said he'd look into it further.
The next day, he called back saying they confirmed it's a bug and it would be fixed in the next maintenance release, but had no idea when that would be.
Very happy with HTC's level of support (after the first few go arounds getting tier 1 to finally understand what I was talking about and escalate).
A T-Mobile forum rep also noted that they've reported the problem and are working on it as well.
Not much else I can do here. Hopefully there will be another software update coming in the next month or 2.

This is happening to me as well. Like you all, when I called Tmobile to ask them about it, they said both the signal fluctuating problem and the random airplane mode are known problems that HTC "is working on a fix for. I guess the pro is that this has been a pretty big phone for both HTC and Tmobile, right? So I'll be optimistic about a fix. OTOH, can I assume this isn't a problem in the ROMs?

Well I hate to disappoint, but this isn't just a HTC problem, I am on the Galaxy SIII and I am experiencing the exact same issue. I'm not sure if T-Mobile uses their own programmers to code the wifi calling and functions, and then just submits it to the manufacturer to add in or what, but there is definitely an issue here.

Maybe that's not a bad thing then. Perhaps an update to the wifi calling app is all that's needed to fix? That certainly would be a lot easier than needing new firmware.
Are you having the exact same issue?

Here is a quote off some research I've done:
It could be done technically. AFAIK all communication between MMS enabled components is done via standard TCP/IP. But in a regular provider setup the MMS store and forward server(s) (MMSC) are only reachable via the providers network. That's why you can not send and receive MMS via WiFi.
It's also the reason why you can not make a call and send/receive an MMS simultaneously when you have only 2G (GPRS/EDGE) connectivity.
Normally android will drop the GSM data connection if there is WiFi connectivity and all data will be routed through the WiFi interface, but there is one exception: The MMS traffic will still go through the mobile data connection.

So normally, if you are connected to WIFI and send an MMS, it triggers your phone to open up the data connection with your carrier just long enough to send your MMS. With TMobile, there is something in the programming that is stopping our phones from doing so. However, this seems more of a GoSMS issue now because the stock messaging apps does perform this function fine.

I'm seeing this problem as well, but the other issue with WiFi calling for me is that it doesn't do touch tone automated systems well at all. Such as voicemail. It straight up doesn't recognise my password input at all unless WiFi calling is off.

I owned the ONE S before the SIII and had the same issue -- It will record your password, you just need to type it a lot slower than normal. I would suggest setting up visual voicemail, or downloading a visual voicemail app like Youmail.

Wifi blocks incoming calls and sms!! - BUG????

Hi
Im having a strange issue that i only just noticed and was wondering if others are having the same problem.
It seems when i am connected to either 5ghz wifi AC or Wifi 2.5gz N,
My phone refuses to accept incoming calls, will call out just fine but will not let me receive.
when I turn wifi off calls come through OK, Just wondering if there is someone who can help.
Update - I have re-flashed both kernel to stock - same wifi being on blocks incoming calls.
I have re-flashed the ROM - again, same issue Wifi seems to interfere with incoming calls and sms. -- Will not receive anything until I disable wifi??
I have also just booted into Safe Mode and the same problem still exists - Wifi is blocking incoming calls, but i can send sms and calls while being on wifi.
Is this a Bug!!! should I report this to CM - could some one else please try this process.
I have also checked and double checked my APN settings and they are correct.
Will do a complete factory reset and see if problem still exists.
UPDATE 2
This has to be a bug I have factory fastboot.zip'd back to XNPH22R
and the wifi bug is still there!
Thankyou in advance

I have the same problem, for which not received a call on the job.
How to solve it? help

I realised my APN settings it was also using 4g but my provider doesn't do 4g when set to 3g only my problems went away.

What Rom are you using? That would help.
Stay to the latest version of the rom

Several problems with my new S6. Please help.

Hello,
I got an S6 through Verizon. It's unlocked. So I'm using it on Total Wireless. Everything was activated last night and was working great. Then, I wake up this morning to check my phone, and as soon as I lit up the screen ALL of my notifications came through that once. I have it set to always allow notifications on the lock screen, wifi sleep is set to always allow connection even in sleep, and data saver is off. I used to have an Asus Zenfone that would do the same thing if it was connected to a router using IPv6. Are there any fixed or known reasons why the S6 does this?
Secondly, out of nowhere today, my phone stopped sending texts and calls. Data was working on everything EXCEPT Facebook Messenger. So before calling Total Wireless, I tried restarting, power cycling, removing and replacing the SIM, resetting network settings, changing it from Global to LTE/CDMA only, and so much more. I eventually caved and called. The reore had me dial *76 to disable call forwarding, although I never even enabled call forwarding. Would that be the main culprit to the issue that I was experiencing? I mean, randomly not sending texts and calls and saying "searching for service" even though it clearly had full signal of LTE and data was still working sounds pretty odd to me. Any ideas?

SMS Delayed and Calls go Right to Voice Mail

Using the device on T-Mobile. Sometimes I'll just get a voice mail notification - without the phone ever ringing. Tested from a desk phone, and sure enough it goes right to voice mail without ever ringing. If I make a call outbound from the Zenfone 6, it will always work. Then I'm able to receive calls for an unknown amount of time. I can reboot and get calls after the reboot, but they will eventually randomly stop.
SMS also come though delayed by hours. For instance someone sends a SMS my way at 2pm, I'll get it at about 4pm. If I send a SMS out bound, I then instantly get all the inbound ones.
Anyone know if I need to whitelist something in battery optimization? So far the Zenfone isn't really good at being a phone. - great at everything else though.

Check your apn settings I think I had to update the default to whatever BYOD APN settings are for T-mobile see if it helps you

Also had this issue on T-Mobile. If APN settings don't fix it, I'd go to Auto-start Manager in Settings > Battery > PowerMaster and allow your messaging apps to run.
For me, I'd get SMS messages only when my screen was on, and some weren't received from contacts, like it shuts the apps off after not using them.

Same here. I'm about to switch providers because of this. What rom are y'all using? I'm on LineageOS 16. @wreid23 can you post your APN settings?
Tried unoptimizing all the messaging related apps, no effect.

So I found that if I turn off WiFi calls come right through. I don't know what the fix is, but I guess that's my work around.

I've found the same to be true for me. Wi-Fi connection prevents calls from coming in. I can dial out just fine.
This is extremely strange since this phone is not even Wi-Fi calling certified and it's not even a feature. This has been my biggest issue with the phone so far because you never know if you miss a really important call.

I purchased a OnePlus 7T for this reason. Can't use this device anymore after getting flack at work for missing and oncall issue due to the phone not ringing because I left wifi on.

Asus denies the phone could be the problem (despite the phone obviously being the only variable). I replied to that thread anyway, with my experience of similar lost calls on a Moto x4 with Wi-Fi calling enabled. Maybe it'll give some engineer at Asus a push in the right direction...

if any of you are rooted there is an alternative for now to enable volte and vowifi: https://forum.xda-developers.com/rog-phone-2/how-to/guide-enabling-volte-vowifi-v2-t4028073

I'm having the issue with T-Mobile 7T Pro, when I got the permanent unlock approval and switched to Mint Mobile sim is when calls went to voice mail, have you found a solution yet? Phone works fine if I use T-Mobile sim, but Mint Mobile sim in the 7T Pro is when the calls go to voice mail and text don't go out, if I put the Mint mobile sim into a Pixel XL all is fine. When I had to quit Mint Mobile becasue of this and go back to T-Mobile on prepaid again, all worked well.

The zenfone 6 is getting volte with the android 11 update so hopefully that fixes this issue
