Busybox is breaking Wi-Fi Calling - Nexus 6P Q&A, Help & Troubleshooting

I've seen people with this same issue and I am sure Busybox is the culprit. Just tried installing to a variety of paths like /system/bin and /su/bin and it still breaks Wifi calling. You may ask yourself how I can be so sure this this is the cause. I uninstalled Busybox and immediately Wifi calling was working again.

How are you testing to make sure its a WiFi call? Are you turning on airplane mode while on WiFi? That ensures all radios are off except WiFi.
Also what do you mean its not working? What happens? Do you get an error message? Does it make a noise? Does it do a song and dance instead? (Kidding)
The more details you give the more likely someone will be able to help.

You're right, my bad. Well, underneath the mobile data toggle in quick settings, it switches to "T-Mobile Wi-Fi Calling" when it's active, and just T-Mobile whenever else. Almost immediately as I remove Busybox, Wi-Fi calling returns. Phone calls also display if it's calling using wi-fi.

No problem, but still I don't know what you mean by it does not work. When trying to call does it say the call is connected or call failed or some other error or what?
Honestly I'm not really sure what the problem or fix is since I'm not super experienced with busy box or unix commands myself. I believe you can manually choose which utilities busy box installs. So the best thing to do first is to narrow down which specific Unix utilities in busy box that might be causing this. Install 1 of the utility in busy box and try to WiFi call, then repeat until wifi calling stops working again. Then come back and report which one it was that breaks WiFi calling.

Can anyone else test this?

Just tested your theory and my WiFi calling still works. Even rebooted in between uninstalling and installing busy box. Was curious because as soon as I read this thread I tested and saw my WiFi calling was not working so I decided to test your theory.. I uninstalled busy box and it still was not working. I rebooted my phone and WiFi calling was working again. I installed busy box and WiFi calling still working. I rebooted again and busy box still installed and WiFi calling still working. Hope this helps.

T-Mobile Wi-Fi Calling Issues

Anybody else having issues with T-Mobile Wi-Fi Calling? Mine connects after a reboot, stays connected, but after a while it disconnects from WiFi calling and more often than not it doesn't want to re-connect again until I reboot the phone.
I suspect it may have something to do with the Doze mode in Android M, but I'm not sure. It feels like once it gets in doze mode it doesn't want to connect to Wi-Fi calling again.
Any known ways to force it to reconnect to WiFi calling, without rebooting?
Not sure what's happening, but I'm not receiving incoming phone calls when connected to WiFi calling. I've turned it off at home (have decent enough voice service) for the time being.

I've seen that too, it's definitely flaky.
Came here just to get more info on this issue. Flaky on mine as well. I'm on T-Mobile. Sometimes users will hear me well, sometimes they cannot. It's typically most flaky when I'm right on the cusp of getting a tower signal. I'll receive a WiFi call and all will sound fine, but as soon as I move close to a window the call quality drops and users on the other end can barely make out what I'm saying. Almost like it has a hard time deciding between WiFi or the cell tower.

Do you have it set to prefer wifi calling?
First day in office tomorrow on a 6p, will test this.

I've had it set to both at different times in the past few weeks. Right now it's set to prefer WiFi because I have poor to non-existant celluar coverage indoors (both at work and home). My wife's old LG G2 has flawless WiFi calling at home.
I have mine set to "Wi-Fi Preferred". It's worked without any problems that I know of both at home and at work, for both calling and text messaging.

This has also been my experience, Connects instantly and stays connected. This is also the first phone I have had that actually hands off to mobile network when leaving a WiFi area without dropping the call. The galaxy s6 advertised this but never once did it work. I get pretty good service at my house and honestly didn't know that I would be able to use WiFi calling when I bought my 6p. Pleasantly surprised.
After a few days, text messages won't send. I get an error -1 code. Had to turn off Wifi=preferred.

See whether this helps:
Dial *#*#4636#*#* as a "normal" call from the stock phone dialer
You should see a menu
Tap Phone information
Scroll down
Tap "Turn ON SMS over IMS" button (make sure that after the button actually says "Turn OFF SMS over IMS" -- this means it's currently ON)
Based on info from this thread: https://www.reddit.com/r/Nexus5/comments/1vahlr/fyi_if_youre_on_tmobile_your_sms_is_sent/
I would not touch any other settings in that menu and if it doesn't help, you should probably revert it back.
Now I'm not sure where these settings are persisted and if they get reverted back when a new radio is flashed for example. Does anyone have more info?
It works but I've found that it causes my phone to stay awake, so I've turned it off. I'd rather lose 1-3% overnight and not 8-10%.

Gave it a try and re enabled wifi calling preferred. I'll post an update, but the error usually takes a few days before showing up.
My Wi-Fi calling was working fine, then I flashed the update to 6.0.1 and it doesn't work at all. It's enabled in settings, strong WiFi signal, but it never indicates Wi-Fi calling.
I had the opposite experience, I updated to 6.0.1 and now WiFi Calling is a lot more reliable than before. Still not perfect, but much better.

WiFi Calling Toggle

I am on the H918 rooted. Is there anything out there to allow me to either quickly toggle WiFi calling manually or do so based on location or SSID?
LG's default method is buried in the menus which is annoying if you have to do it multiple times a day. There is a Tasker plug in, but it's old and appears to be made for Samsung phones.
You could try shortcut master lite.
Another option is to enable wifi calling in settings.
When you want to use it, turn on airplane mode.
Then turn on wifi. Wifi calling will pop up in about 10 seconds.
Make your calls. When done, turn wifi off.
Turn airplane mode off and you'll be back to data calling.
You don't want to have wifi calling and data on at the same time. There appears to be a bug that borks the data calling after having wifi calling on at the same time.

Wifi-Calling T-mobile?

Hello Everyone,
Does anyone know if this phone supports Wifi-Calling via T-mobile?:cyclops:
It does. I tried it last night. Turned to airplane and turned back on wifi, made a call just fine over wifi on T-Mobile.
I had no idea it could do that, but since my house is a bit of a Faraday Cage my G5+ starts the call as a provider call (T-Mobile) & jumps over to WiFi as soon as the connection is made. Totally threw me for a loop, I've wanted this feature on an OON phone for several years... way to go, Moto... oops, I mean Lenovo
Dave in San Jose
I might be missing something but it doesn't say WiFi call when set to WiFi preferred and I'm on WiFi. I try turning airplane mode on and WiFi on and get a message that I have to connect to a network. In TMobile.

Did you enable it in settings? I've found it to be a little finicky sometimes, but it usually works pretty well.
It works but for me caused SMS/MMS delivery issues with the wifi router i was on. So i turned it off. I can turn it on when i need it for now, no need.
Get an sms app that supports forcing sms over cell even if you are on wifi like textra.
Sorry to bother, but it doesn't work for me. I have wifi preferred and wifi calling enabled, but it doesn't work when I do airplane mode-with-wifi on.
Any chance this could be due to APN settings? Can someone with this working share their APN? I know on my previous phone (Nexus 6), the T-Mobile APN settings were confusing and tricky. Thanks in advance!
Turning on airplane mode got wifi calling and SMS to work for me no problem. I have "wifi-calling preferred" selected in settings - is there any good way to get it to switch over automatically when cell service is poor? would like to not have to hit airplane mode every time.

Actually, you shouldn't need to turn on airplane mode. That seems to just be a way to confirm it is actually using wifi since it ensures cell radios are turned off. It will automatically switch if you do not turn on airplane mode. If you look at the phone when a call is connected, it will confirm that it is a wifi call. This is a small drawback to the Moto G5 Plus software. Unlike other phones that actually tell you that the phone will use wifi in the notification area, this phone only acknowledges the wifi calling after the call is made or received. It would be nice if they would change that.
However, I am having a problem with mine not working properly on wifi. It seems that calls will not always go through to my phone. The phone will ring, but won't let me answer the call. It will quite often show the same call repeatedly even though I cannot answer the call. The caller tells me they hear nothing the entire time it should be ringing and eventually gives a busy signal. It doesn't even go to voice mail so they can leave a message. Sometimes it works perfectly, but there is no way to know when it's not going to work. I used to be able to get it to work again if I switched off wifi and connected to LTE, then made a test call before turning wifi back on. Now I can't seem to get that to work any more. Anyone have any idea what could be causing this?
Hi brothers,
Please, can you share some screenshots of these VoWIFI options in settings?
I feel the "reteu" (european) version doesn't have enabled VoLTE and VoWIFI.

Wifi calling - inconsistent with 8.1 Oreo - T-Mobile

I'm finding that WiFi calling stops working randomly. A reboot gets it to work properly again. I have my advanced call settings on Global and Wifi Preferred as my option.
Anyone else having this issue with Oreo 8.1 and T-Mobile?

I've had this issue since I upgraded to 8.1. I've been planning on doing a factory reset to see if it fixes the problem, but I really don't want to go through the hassle of setting everything up again.
I have no cell signal at my desk at work, so I use the WiFi calling often. However, I have noticed something rather strange. If I try to make a call or send a text, it will sometimes say something like "No WiFi network available". There have been a few times after it has done this that I have received a call on WiFi, and then it will work fine for a while. Otherwise, a restart fixes it.

Another thing that I noticed is that when on Wi-Fi calling, sometimes the phone will only ring once before a call goes to voicemail. Seems like there may be a delay in the call coming through. I generally have a good Wi-Fi connection, but like any Wi-Fi connection, it can come in and out occasionally.
I want to avoid a factory data reset as well.
I have the same problem Essential on Sprint
I am also experiencing this since the 8.1 upgrade, 8n T-mobile. Multiple networks that had WiFi calling pre-update are no longer functioning on either of our phones(wife and I both have them). I often work in a basement, so this is an important function for me.

Anyone else having issues with MMS on T-Mobile (international version)?

I ordered my OP8P directly from OnePlus, but my MMS doesn't seem to be working. Anyone else had the issue?
I actually got a message that the settings were not correct, and that the correct ones were being sent to my phone (had never seen that before). I looked at the APN info, and it seems to be correct... based on memory.
I'm on T-MOBILE also and received the same message. The phone had an update so I installed and rebooted the phone. All call,text, MMS, data worked like it's supposed to. Try rebooting?
I have issues when connected to WiFi, message comes in but doesn't download

I've tried rebooting. Things are a lot better, but I still have some issues with calling out (can't remember the message... will try and get a screenshot next time). If I immediately try again, the call will go out.
I'm also not seeing any wifi calling. The feature is enabled, but it doesn't seem to be working... even on the "wifi calling preferred" setting.
Just wanted to post an update.... still having issues. MMS pretty much never works with wifi on. For this reason, my wifi is off pretty much all day. It never fails that as soon as I turn it on, a picture or group message comes in.
Also, this does not affect SMS or RCS messages, which appear to come in over data somehow.... just MMS.
Need a fix bad.
I'm having the same issues with T-Mobile. I'm leaving wifi off in the meantime. Hope there is a fix soon.
That was supposedly fixed with the last update. What software version are you on?

Hi, not sure if it would make a difference but I'm using Google messages with the chat features enabled. I never noticed anything unusual though but I live in Louisiana. Sorry to hear that. I know there is an option for mobile and wifi (dual-channel network optimization) that I haven't been using. Anyway I hope this clears up for y'all.
I'm on 10.5.6. I just went to t mobile and got a new sim card.. It didn't resolve the issue.
Use Textra app, go into settings for Textra and it has option for TMobile WiFi, works great

You really, REALLY had my hopes up. It actually makes sense, but it doesn't work. I tried with both on and off... no luck. MMS messages (both inbound and outbound) are stuck until I turn off wifi.

I used to use the Textra app, but really prefer Google Messages for it's web app. I am on the PC all day, so it's aggravating to have to pick up the phone all the time. I've tried MS Your Phone, but it's not as easy to use, or as reliable.
I created a thread with a similar (but opposite) issue to what you're experiencing. A friend of mine with an international 8 Pro on TMO is having the exact issue you are.
https://forum.xda-developers.com/oneplus-8-pro/help/receive-mms-wifi-calling-tmobile-t4088673
Didn't get any help from that but you can try the APN trick for a temporary fix until it's patched for real. I also created a thread on Reddit for this and I think I found the solution. I use Textra, but that alone didn't help. Someone on Reddit told me to disable the stock messaging app, as well as revoke it's permissions to everything. Since doing that I'm no longer having issues. It's only been about a day so we'll see how it goes from here.
Hope I could help!

Duplicating the APN worked (of course, I did the whole thing then swiped back, thinking it would save, grr). I'm guessing it won't last long. It's just as easy to disable wifi for it to send... so weird that you're having the opposite problem.
**EDIT**
Nevermind... it didn't work. I was able to send out with wifi on (which I couldn't do before), but my wife's test message wouldn't download until I disabled wifi.
I had frozen the stock messaging app on day one, with tibu. I thawed it, revoked the permissions, and disabled it via settings this time. No luck "Not sent. Tap to try again".
Anyone find a fix for it yet? I thought 10.5.8 would help but I still can't receive or send MMS on WiFi.

Granted, I haven't done any extended testing yet, but I can send/receive MMS now with wifi connected. I upgraded about 4 hours ago, and this is probably the longest I've ever had wifi on.
Now that you've posted this, I'm skeptical it will last, though.
**EDIT**
Yep. MMS is still broken when on wifi. Geez....

The latest update seems to have fixed it for me. I was also having issues receiving calls. Callers would get a busy signal. The update fixed that as well. Maybe try taking your SIM out, reboot, then put it back in and reboot.
That didn't work. I'm finally getting notifications from my sports app after the 10.5.8 update. Just have to fix the wifi now.
Wifi still dies on me, but not with the ! on the icon. Just no traffic. I had to toggle it. But nowhere near as much as it used to. The MMS issue is the only reason I don't leave wifi on. I was really hoping it was fixed.
Same issue here even with most recent updates. MMS will work 1/10 times over wifi (sending & receiving) but not the other 9 times.
Since the update I've also noticed wifi issues - they may have been there before but didn't notice. Wifi seems to hang, I sometimes see a "!" next to the wifi symbol. In many cases I turn WiFi off and the connectivity issue in whichever app is resolved.
So at this point on TMobile there is no reason to keep wifi on, which is unfortunate because with their "5G" I actually get half the speeds of LTE. ?

Pretty much everything you said. I'm really upset and disappointed. I'm actually considering returning the phone and going back to the OP7P. Not even sure what the return policy with them is...
