[T-Mobile Samsung Galaxy Note 3] Kal-El7:
Friends, couple things.

I noticed (I think) someone mentioned that he (someone from San Antonio, I think.... [MENTION=3561341]dongarritas[/MENTION] ? ) experienced immediate hangups when making a call while using WiFi Calling. I was experiencing the same and I couldn't find where I read that post so I could monitor if he had any progress.

Here's what I found -

The "WiFi Preferred" option was enabled. This was the culprit (now) when (before) it never was the culprit in previous Tweaked versions or previous stock ROM versions for me personally. This could be a bad install on my part or something else, as I do not think TweakedN3 3.5 is at fault.

Now if you enable the last option "Never Use Cellular Network", turn off WiFi Calling from the on/off switch in the WiFi Calling settings and then turn it on again, then WiFi Calling works. If you switch back to "WiFi Preferred" but do not turn off WiFi Calling from the on/off switch to then turn it on again...then the repair sticks around forever and now you can be on "WiFi Preferred" option, still be able to make your calls while being on a WiFi network, leave your home and start driving and the phone gladly defers to cellular network.

*BUT*

If you turn OFF (the green on/off switch at the upper right hand corner) WiFi Calling and then turn it back on again, then making a call using WiFi Calling is broken again and immediately hang-ups occur as soon as your phone attempts to make a connection. And yes, at this point the "WiFi Preferred" option indeed is still the enabled option. I would have to go back to electing the "Never use Cellular Network", turn OFF WiFi Calling, turn it back on again, then MAKE A CALL and have the call successfully connect, then, WITHOUT TURNING OFF WiFi Calling from the on/off green switch, go and re-enable the "WiFi Preferred" option and BAM - now you're golden again. Now your phone will utilize either WiFi or Cellular to make calls depending when you're jumping on a home network or running out of the house and hopping on T-Mo's network. Make sure to never physically and literally turn off WiFi Calling or else the malfunction will return. So there's your workaround where it'll stick for good...but only so long as WiFi Calling on/off switch is never messed with.

Dwitherwell asked me whether this behavior is evident on stock retail NF4, but I haven't tested it yet. For the record, D's WiFi Calling works fine. I just wonder if repeating my steps would produce any of these results for anyone.

I would like it so that if I switched off WiFi Calling, then switched it back on again with the "WiFi Preferred" always enabled....that my phone will function normally. A bandaid resolve is still just a bandaid. I will see if I can make a little time to attempt stock NF4 tests.

Off topic, S5 sms/mms option when installing (or Modificatinator)....other than that cool Pop-up Display feature, what else might the S5 sms/mms have which could favor me installing it in place of the Note 3 sms/mms app? Is there anything about the Note 3 version of sms that would make you wanna stick with that versions instead of hopping over to the S5 version? Are there any other cool things that you can enjoy with the S5 that makes you go Hmmmm?

Thanks, guys.

If not for SwiftKey's superior prediction technology, I couldn't type that much, that fast on my cell phone. Just sayin'.
