After a recent T-Mobile update to my Samsung S-22 phone a few days ago,
WhatsApp VIDEO calls will not connect, neither incoming nor outgoing.
PHONE calls and TEXTING via WhatsApp do work, both incoming and
outgoing. The probem is limited to VIDEO calls via WhatsApp. I
uninstalled and then reinstalled the app, but the problem continues.
The network name on the phone is the same as the network name on my
laptop (internet is thru Xfinity); internet works fine on the laptop.
Thinking if I could uninstall the recent T-Mobile update, maybe that
would fix it, but can�t find a way to undo the update.

All ideas, pointers, suggestions welcome. TIA!

George

P.S. The WhatsApp version is 2.23.1.76
P.P.S. Is there a newsgroup for WhatsApp?

To clarify: where I say PHONE calls do work, I mean VOICE calls via
WhatsApp do work, since obviously the phone is the device . . .

Google says (samsung s-22 whatsapp videocalls not working):

Why video call is not working in WhatsApp in Samsung?
Grant Necessary Permissions

So, if you're having issues making use of the WhatsApp call or video
feature, you should check that you have granted it the necessary
permissions. To do this, go to 'Settings' on your Android phone and
click 'Apps'. Next, scroll till you find WhatsApp, then click on it.Oct

WhatsApp Call Not Working: Here are 5 Ways To Fix It - Dignited

Cheers, Carlos.

Carlos, thanks for replying. I should have mentioned that I googled the
problem extensively before posting in the newsgroup. Tried every fix
that Google came up with on different websites (and then some),
including checking Permissions (none are showing as denied).

What bugs me is that everything worked fine before the T-Mobile update,
and that apparently there is no uncomplicated way to undo the update.

Again, thanks for taking the time to reply, it's appreciated.

I just tried video chat in WhatsApp with my phone, and it is still
working. Doesn't help you, just to know that it is not a general problem.

Cheers, Carlos.

Thanks Carlos. Yes, definitely not a general problem. I discovered
that if I go to any wi-fi hotspot instead of my home wi-fi, WhatsApp
video calls will connect, both outgoing as well incoming. And yet, the
home wi-fi works without any problem on the laptop!

Oh, the mysteries of modern technology!

Regards,

George

Well, you are finding out things. It is not an update to the phone, but
something in your router (or land ISP) that is not proper, or that it
conflicts. You have to find out what.

Google that router model and whatsapp, or that isp and whatsapp, or
whatsapp and wifi.

For example:

<https://faq.whatsapp.com/829451934973485>

«When experiencing issues with WhatsApp calls, please try connecting to
a different network (such as Wi-Fi connection instead of mobile data, or
vice versa). Your current network might not be properly configured for
UDP (User Datagram Protocol) which may prevent WhatsApp Calling from
functioning properly.

If you're unable to make or receive WhatsApp calls after connecting to
your Wi-Fi connection, make sure your router's security settings and
firewall configuration aren't blocking certain types of connections in
order for WhatsApp Calling to function properly.

If you have any additional questions regarding UDP or Firewall settings,
please contact your service provider or network administrator for
additional information.»

WTF? How on earth can the network administration do anything if whatsapp
doesn't say what ports and types of connections must be opened? I can
not open every port!

I can work that out with a profesional router with a proper firewall
log, but not on a shitty ISP router.

Cheers, Carlos.

Carlos, you've given me some more things to look into. I also messaged
WhatsApp Support; will update here when/how this gets resolved.

Thanks again,

George

Carlos, after googling a zillion more sites, it turns out the solution
was in the Arris modem, which had the Security set at "Maximum".
Changing it to "Typical" allows WhatsApp video calls to work.

At first had some concerns about making the change, but went ahead with
it since all apps on the phone were downloaded from reliable sources,
and the laptop has its own firewall.

So I hope this post helps anyone else who might encounter this WhatsApp
connection problem on their home wi-fi.

That's good news. Thanks for sharing. :-)
