WiFi availability alert and connection preferences

Actually, I will ask this in the opposite sequence as the subject...

 

1) Under the settings for wifi cally, there are the connection preferences.  The first option seems odd to me in the way that it is worded.  I am wondering if it is even correctly worded or not.  For the option of "Wi-Fi Preferred," the setting is described as; "Wi-fi network is preferred over cellular network when making calls. Calling requires that you stay in Wi-Fi range"

 

So if this setting is only meant to make the preference of wi-fi over cellular, why would you have to stay within wi-fi range?  Wouldn't that really mean that it is wi-fi only, which is the third option?   The second option to prefer cellular over wifi doesn't say that there has to be cellular in range.  To me it sounds like the description of the first option to prefer wi-fi is actually incorrect and that it should be worded more like how the description of prefering cellular is written (except obviously inverting the terms).  But if the wording is correct, can anybody explain why? Or how it is different from the Wi-Fi only option?

 

2) Before I get into it, let me preface this by saying that I have had this issue across two devices and multiple networks...

 

My problem is that sometimes (not all the time), I will be on a call and then have the person on the other end start freaking out that the the outbound sound has dropped dramatically and suddenly.  Every single time that this happens, I will look at the face of my phone (while remaining on the call) and the blue alert ballon will appear in the top tray, letting me know that wi-fi calling is available.  The icon is not there before the call and is actually rarely ever there, except during these instances.  I am not touching anything and nothing is changing as far as proximity to my available network (with the router anywhere between 5 to 10 feet).

 

What triggers this alert to come up, stating that wi-fi calling is available?  How I look at it, if this icon is set to pop up whenever I am in range of a network, it should basically be showing most of the time on my phone, as I work from home and am always seated with my phone right near the router (also a very fast connection).  For me, it looks as if it is coming up as my bars dissapear.  But in a different thread, I was told that the alert should have nothing to do with the cellular signal.  So...

 

2a) What is it that makes the alert come up (besides the obvious function to notify the user)?  What is the trigger?  I can sit here without the alert of availability and still go to the settings and choose wi-fi only and use it fine, so I know that wifi calling is available even when I do not get the blue dialog bubble alert showing.

 

2b) The core issue that this alert seems to be causing is that there seems to be a definite connection between the alert of wi-fi availability and the dramatic drop in quality of my outbound voice, mid call.  Everything sounds fine coming in and the calls do not drop, so it doesn't sound like it is a weak signal issue and the only common thing that I can find is that when I have this drop in the outbound quality of the call, that it is always accompanied by the wi-fi availability alert. And, these are the only times that the blue bubble ever comes up.

    To answer your question about the wifi calling

    Wifi preferred means it will hang onto wifi as long as possible until it has to switch to the mobile network and advises you to stay within wifi range to continue to use wifi calling as obviously once you are outside of wifi range you are no longer using the wifi calling feature.

     

    Wifi Only means it will turn off your mobile network completely and only use wifi whether you are in range of wifi or not.

     

    The mobile preferred option does the opposite of the first and really doesn't say "you need to stay within mobile network range" because it assumes you always will be (unfortunately not always the case)

     

    Really overall they are just blanket statements to assist with using the wifi calling feature and are not geared toward regular calling just wifi calling however I do see where you are coming from and will pass the feedback to our device team.

     

    For the issue with the outgoing audio you are correct (or you were told correctly in the other thread rather) that the simple notification should not effect your call audio what you could do to test that is disable the wifi calling all together so that the notification will not pop for a few days and see if you have any calls that suffer from the same issue (or however long it takes I don't know exactly how often you have the issue) once we do know for sure it is that notification we can report the issue to HTC for review.

    "Wifi preferred means it will hang onto wifi as long as possible until it has to switch to the mobile network and advises you to stay within wifi range to continue to use wifi calling as obviously once you are outside of wifi range you are no longer using the wifi calling feature." -

     

    Actually, that isn't what the second sentence in the details of that option states, but I think that is why you later said that you "will pass the feedback to our device team."  So it works as I had expected and not as it is stated, where the second statement  more broadly states that any calling while that option is chosen would require being within range.

     

    "the simple notification should not effect your call audio what you could do to test that is disable the wifi calling all together so that the notification will not pop for a few days and see if you have any calls that suffer from the same issue" -

     

    The only problem is that I can go several days without it happening even with it enabled.

     

    Can you tell me specifically what triggers the alert to pop up?  I would have thought from a developmental standpoint, that it should have been popping up whenever it was available, but I know that isn't the case because the alert is rarely shown, evn in places that I know (through testing) that it is available.  Computerslayer said that it shouldn't be triggered by a weakening cellular signal, which would have been my second most logical guess as to what might trigger it.  If I can figure out what triggers it to come up, that is most likely going to lead me to what is the cause of the audio quality dropping, because the two events are unquestionably connected. It may not be the appearance of the icon, but the circumstances that are the trigger for that alert to pop up.

    Hi Wattsup (does using your username also count as a greeting by default? ) and Keith,

     

    My understanding of the icon is that the phone is both connected to a wifi network and through that network, registered to T-Mobile.  Keith, can you confirm that?

     

    Wattsup, I'm curious about the control test that Keith suggested - disabling wifi for a couple of days and keeping track of audio quality of your calls. How has that gone?

     

    Also, it might be helpful to look over your error code logs when this happens - once you turn on wifi and wifi calling after the test Keith suggested is all done.  When the problem occurs, finish your call, go to the wifi calling app->settings>error code logs.  May there will be something helpful there too.

    Yes I indeed will pass that information off to my design team for clearer descriptions of the settings in future devices and updates to be sure.  As far as what triggers the wifi calling indicator it should pop up depending on the setting:

     

    wifi preferred:

    will enable wifi calling as soon as you pickup wifi

    if you are on a call it will wait until the call is complete and then switch

     

    wifi only:

    will enable wifi calling as soon as you pickup wifi

    you aren't going to be on a call outside of wifi

     

    mobile network preferred:

    will enable wifi calling only when the mobile network is gone or nearly gone

    will not switch unless prior requirements are met

     

    The fact that you are finding the audio degrades DURING the call and there is no handoff means that you either started on a wifi call and it was good until some point or that the mobile network call quickly degraded and so the phone is letting you know you have alternate options available,

     

    We really would like to test it out with the wifi calling disabled for a few days or you might even try setting it to "wifi preferred" starting a call with wifi off then enabling it during the call to see if you can create the issue while you are watching it.

     

    Let us know what you can do and how it goes.

    "The fact that you are finding the audio degrades DURING the call and there is no handoff means that you either started on a wifi call and it was good until some point..." -

     

    Not the case.

     

    "The fact that you are finding the audio degrades DURING the call and there is no handoff means...the mobile network call quickly degraded and so the phone is letting you know you have alternate options available" -

     

    This seems to be exactly the case, but this is what is confusing me.  Why would the alert itself degrade the outbound audio?  Everybody says thatthere is no handoff, but aht happens is that the recipient will complain, I will look at the phone and have no bars for cellular, but the blue bubble will show up.  But it really doesn't act like a weak or lost cellular signal if I am, let's say, out in the street away from any wifi network.  In those cases, the inbound audio will also degrade (usually becomes warbly) and teh call drops very quickly.  In these cases that I am reporting, the recipient isn't receiving a warbly voice, but a dramatic drop in the volume of my voice and nothing changes to the inbound voice and I can remain like this for as long as is tolerable without the call dropping.  The bubble is blue, not green, so I get that this isn't a true and complete handoff, but there is definitely something different happening when loosing cellular signal within range of a wifi network during a call and loosing cellular signal just out on the street.

     

    I turned it off and will leave it off for the rest of the week and report back, but like I mentioned before, I can go several days as it is without experiencing the issue.  The reason that I can randomly loose bars like this is because I live right at the ocean and while I normally still have solid reception here, something odd like a quickly approaching marine layer can abruptly wipe out my signal.  And I am not saying that marine layer is the absolute cause, just pointing out that there are unique atmospheric circumstances that cause my bars to go from 60 to zero in a moment.  And before the whole conversation jumps to blaming atmospheric conditions at the beach, I have these same experiences elsewhere when within reach of a wifinetwork at friend's businesses, etc. I am just pointing out that I work/live by the ocean.

    OK, I turned it off from last Wednesday to today.  But I am not sure what I was supposed to notice or not notice during that time or now that it is on again.  Like I said before, I could go for days without the issue happening, so I have no idea if it would have happened during the time that it was off or not.

     

    "you might even try setting it to "wifi preferred" starting a call with wifi off then enabling it during the call to see if you can create the issue while you are watching it."

     

    - Actually, this can't be done.  It won't let you turn it on during an active call.  I just tried it and got a psuedo error message telling me that I couldn't turn it on during a call.

  • 7. Re: WiFi availability alert and connection preferences

    Guess what, the ICS update fixed the problem.  First thing that I noticed was the the alert for the availability for wifi calling (the blue bubble) is on constatntly when I am within range.  I have no idea what it was, but the issue somehow seems to have been tied to how these alerts were just randomly coming up when the alert should have been on all of the time.

     

    Also, I know that everybody keeps saying that theer is no handoff from cellular to wifi, but to me, this still seems to have been what happened.  Now hear me out...Now that ICS has fixed the issue of the alerts popping up randomly in the middle of calls, now some calls are starting off on wifi right from the start (when I have no bars).  And everybody is complaining that they can barely hear me or ask me to speak into the phone.  So using wifi calling, I called two of my friends who most frequently experienced the issue of my outbound audio dropping in the middle of (cellular) calls and asked them if the low audio sounded the same and both of them said yes, only now it is the whole call, instead of suddenly dropping down in the middle of a call.

     

    I know that there is all sorts of documentation and rationalities for why this wasn't the case, but I am now testing wifi and teh low outbound audio quality, with multiple people who heard this before and they are identifying it as being the same as what was occuring during the middle of cellular calls before and when I was looking at my handset during those issues before, two things were happening 1) I had no cellular bars, but was not dropping the call and 2) the wifi calling alert had popped up during the call.

     

    As theorhetically impossible as several people have said that this is, I now don't have a doubt in my mind that I was shifting back and forth between cellular and wifi calling.
