Issues that need high time resolvigg

Suraj Sugathan

Undoubtedly this app offers amazing clarity but it sacrifices 2 extremely important factors.
Me being from the uae, in order to download/update it I need to be connected to a VPN without it there's no way I can do anything with the app.
Secondly, I can't talk directly from the device for even 10 mins the battery heats up like there no today and majorly for this reason I switched back to Skype.
And vpn is a big mistake in order to make calls.
If Google finds a solution to these things and brings a clean update this would be the best calling app ever. So cheers hoping for refinements and network resolutions



Awesome app with crystal clear sound and visuals. The only thing which needs to be change is the battery drainage. It actually drains the battery more faster than any other similar apps but better than those apps apart from the battery drainage issue which can be fixed I believe.

Superb clarity
