WhatsApp Calling not working after iOS14 Update

After update to iOS 14, I have run into 2 big issues:

  1. WhatsApp Calling feature does not work, normal messaging works but the Video / Audio Calling is not working. It keeps asking me to switch from 4G to WIFI but none of them work. Everything was working fine before the update. I have re-installed WhatsApp, re-installed iTunes but still nothing works
  2. Unable to take backup on my laptop after the update. It just hangs and does nothing.. I have left for 5-6 hrs but still does not do a full backup on laptop. Previously it took 20 min at max.


Has anyone faced this issue? I can't roll back to the last saved backup on laptop as I deleted it by mistake. I dont want to pay Apple hence dont use iCloud for backup

Yes I’m also having problems with WhatsApp calling on my device with iOS 14. I have gigabit fiber optic at home and 2 Wi-Fi access points hardwired into a gigabit Ethernet network. However, if I try to make a WhatsApp call I see WhatsApp says the Wifi connection is “poor” and it is switching to cellular for better signal. This causes to call quality to plummet to the point of being unusable. If I immediately call back using an iPhone on iOS 13 the call goes through with no problems. Speed tests take during call attempts show 500-950 Mbps with a 2-3ms ping. So the problem is not the network; it’s the iPhone running iOS 14.

I too had the same problem. Basically followed instructions from tahirnazir and this worked😀


Background: when I initially upgraded to latest version 14.1. A message popped up at the end asking WhatsApp wants access to ...’local network...’ I can’t remember the exact wording. I thought it was dodgy and declined access.

This is when I started having problems with audio/video call feature on WhatsApp. So either allow WhatsApp access when upgrading or go into settings > WhatsApp > select local network to update. The problem has been resolved for me and all WhatsApp features are working as before.

Told by WhatsApp support that the only way to resolve was to restore phone. After restore nothing had changed. WhatsApp still did not appear in ‘Privacy’ ‘Local Network’. But I made a call and the pop up box appeared.....’do you grant permission for WhatsApp to access your local network?’ When I agreed, it now appears in ‘Privacy’ ‘Local Network’ and I can now make calls perfectly........so problem resolved.

note: follow Apple’s instructions carefully when doing restore.

Yes I have started to face similar issue too.

I am using iphone Xs ios 14.2 and did a test call from my phone to my wif's phone which is also iPhone XS ios 14.2. I did a video call test and I get the error saying reconnecting and the video call becomes very choppy and eventually have to hang up the call.

When I switch to LTE, the quality of the call improves, but I can't keep using my data.

I have re-installed Whatsup, rebooted my iphone several times, but still no luck.

Thanks a lot lakitaa . Your solution worked perfectly for me. By lowering the WiFi router security firewall protection setting to Low (previously it was set to High) , I was successfully able to have a smooth WhatsApp Vedeo and Audio calls using WiFi option , successfully tested both incoming as well as outgoing WhatsApp Video/Audio calls (along with 4G LTE mobile data turned on in parallel to WiFi).


I tried all previous suggestions (turn on Setting -> WhatsApp -> on Local network , turn on Settings -> Privacy -> Local network) and both these important solutions did not help.


Interestingly even after updating iOS version to 14.2 (or 14.2.3 ?) , my iPhone did not have any problem, until the home WiFi router was upgraded to a new Nokia ONT (Fiber modem) plus inbuilt WiFi router combination. Thats why I was not fully convinced with the iOS update itself (which earlier suggestions relating to Local Network setting pointed out). So, its quite likely that recent WiFi router updates or WiFi router settings relating to network security such as FireWall level has interfered with the WhatsApp audio/Video calls. Before modifying the firewall security level (to Low), i did a small experiment viz., using another Android phone as a HotSpot and using that WiFi connection in the iPhone . Surprisingly in this combination, iPhone was successfully able to make both incoming and outgoing audio and video calls. This successful experiment gave me the confidence to lower the WiFi router 's security level setting and then could finally conclude and solve the problem. Thanks a bunch . note: This resolution summary (3 or 4 solutions provided so far) needs to be formally sent out to the Apple dev. / support team community and to that of WhatsApp tech support team. Both companies need to have a clear blog / vlog / tech-note explaining this problem and the potential solution(s).


Note: still we need to find out exactly how the iOS upgrade has exposed these inter-dependent intricacies between router/firewall/OS/hotspot settings. Interesting corner case that has been hiding for long term and just got exposed as part of iOS 14.2 upgrade process. It will be nice if the tech-note or blog explains the technical details for software enthusiasts like me.


Best regards and thanks again.
