[T-Mobile Galaxy Note 4 Android Development] lazer9:
Full explanation of my Wi-Fi calling issues.

I really don't get what it is with my phone or setup - combo of apps?

All I did was bridge my 3n1 cable modem per specific instructions online as others have done with the Time Warner Ubee combo due to it being more unreliable at performing optimal Wi-Fi and as a router. So last evening I hooked up the T-Mobile issued "Cellspot" - Wi-Fi router. Proceeded to set it up which was rather simple beings I initially had tried one before. It seemed after this, my Note 4 started acting up out of the blue even though it had strong Wi-Fi signal and was on Wi-Fi in regards to my dreaded "Wi-Fi" calling issues that I thought finally I had narrowed down to that mentioned app "Alarm Clock Xtreme".

So I called their tech support via 611, described the situation. How my phone was constantly requiring reboots to even get Wi-Fi calling to re-enable and then after like 2 or 3 calls it would start reverting back to the towers. Meanwhile, my girlfriends cheapo tiny Android "Entry Level" T-Mobile phone they just gave her during our last visit in exchange for me adding her to my plan and nixing her pre-paid would flawlessly continue to be able to make and take Wi-Fi calls. Finally, we did the obvious 1st troubleshoot which I should have thought of. Shut down everything - Cable modem - Cellspot - Computer - Even my Note 4. Waited over 30 seconds and proceeded to re-start each device in order. This seemed to help some as I was able to receive the "Call back" to my Note 4 from the tech that was working with me and keep on "Wi-Fi" call. Even was able to proceed after call ended to make some test calls and keep on Wi-Fi.

With that said, just before bed, I tried some more calls and things started acting up again. I kept removing "Wanam" thinking maybe it was the cause. No difference. Finally, as I have been trying some different "Call Recording" apps out, I started trying some other additional "Call Recorders - mainly "Auto" ones. Can't even remember all the ones I tried. After many uninstalls of them as they now seemed to be the culprit and reboots into Recovery - Clearing Dalvik & Cache then just to be safe - doing a "Fix Permissions" and rebooting WITHOUT any call recorders installed now, thus far, I have stayed consistent again getting Wi-Fi calls to connect and maintain from aprox 6+ tests last night and so far my try's this morning.

I'm still puzzled with some observations and questions with all I've been through:

- I initially got the Note 4. Verified I was on ANK, unrooted... Proceeded to do a "Factory Wipe" as instructed. Then proceed to "Root" and flash TWRP successfully per the thread in "General Forums" here.

- Had downloaded latest V9 current "FireKat" build, and proceeded step by step via the flashing instructions.

- The one boo-boo I had then done after letting phone settle also as noted in OP is install Titanium Backup and "Selectively" install some of my favorite apps via Restore. Now I am thinking even though at the store the other night, I finally did a "Factory Wipe" and got back my Wi-Fi calling consistently at that point. I only installed apps that I had saved in my email OR via PlayStore from this point and avoided using TIBU to Restore anything this go around BUT I am wondering since I know "Factory Wipe" at least according to the wording in TWRP only wipes the caches, and data partitions, if it is possible due to me going against the "rule" noted with this ROM of initially using TIBU Restores (non-system) apps though but never the less, if my best course of action would have been to completely start fresh with Odin to ANK, re-root, install recovery, and follow ROM install directions this time to an T including NOT restoring ANY applications via TIBU if that makes sense?

- Also, the big question at this point. Does anyone running this ROM use any particular "Call Recording" app with success along with making consistent calls over "Wi-Fi"? And also related to that, I have tried to use the selection within "Wanam" also to either turn on "Recording" ability period and even the selection it has for "Automatic Call Recording" to no avail. It simply doesn't work. Is that normal? Am I missing something or combination of settings to use to actually enable the Call Recording button through "Wanam" OR preferably "Auto Call Recording"?

Thanks for any and all who have read through my essay, lol, and have any thoughts on helping me troubleshoot things further or suggestions on where to go at this point! :highfive:
