Chalk Functionality Issues on IPhone 7

Chalk Functionality Issues on IPhone 7

Hello, 

 

After testing Vuforia Chalk on several devices, we have noticed a huge difference in performance on different Smartphones, despite testing under same conditions and in identical environments. 

 

While Vuforia Chalk was running great on iPhone 10, audio and video quality on iPhone 7 was very poor. On the other hand, we tested the software again on iPhone 6 and it was running much better. 

 

Could there be a specific reason for this huge difference in performance? Are there any additional software requirements that might impact the quality of calls (like newest iOS updates for example or additional plug-ins)?

 

Best Regards

No additional plug ins are required to run Chalk. Have you noticed consistent poor call quality on the iPhone 7? Are all of these phones on the same network (wifi or cellular data)? Can you confirm the iOS version on these devices? We now require iOS 13 for Chalk on iOS devices. Are all of the devices also running the latest Chalk version (3.0.2)?

Thank you for your reply,

 

Yes, we have noticed a consistent poor call quality. We were testing smartphones connected to the same wi-fi network as well as using identical mobile connection from the same internet provider. 

 

Devices were running the latest Chalk version. The iPhone 7 was running the iOS 13.3.1 with the pending update to 13.4.1. So we were wondering if the newest iOS version was required or just iOS 13.0.

Only iOS 13.0 is required. One thing I would suggest is ensuring that other apps are closed on the iPhone 7 prior to starting a Chalk call. 

 

Can you expand on what part of the call was poor quality? Is it both audio and video or just one of them? Do you notice the colored circle at the top of the call changing to gray during the call? Have you tried enabling Low Bandwidth Mode? If so, does that help with the video issues?
