Hi Lior
I have done some testing on iOS (after the firmware fix) and can confirm that you can have the QuickCapture and the Trimble GNSS Status app running at the same time, both displaying the same (Trimble) reported locations and accuracies. QuickCapture was connected to the R1 using Bluetooth, and the use of the phone's internal position source was not required.
For Android, the use of Mock locations and Location Extras is required. The GNSS Status app is still used for configuration and to connect to real-time resources. QuickCapture should be configured to use "Internal Location Service" after GNSS Status has been set as the Mock Location provider in Android Developer Settings.
Could you share the phone devices and operating systems you were using and we can see if we can replicate the issue our side?
Thanks
John
