I'm leaving feedback about the latest One UI 5, beta software firmware (version ZVK3). This patch was installed on November 7th.
My mobile provider is T-mobile. When taking a phone call, my cellular mobile data connection cuts off and the signal indicator was showing I didn't have a connection. It also briefly switched to the edge 2g network for a few seconds, before staying disconnected.
As soon as I ended the call, my mobile network data returned and I could access the internet again.
I recreated the scenario later in the day, and got the same result. While on a phone call, my cellular data gets deactivated somehow. On a wifi connection, the issue doesn't appear, so it's only while on mobile data.
Not sure if it's an isolated incident, or if other people are experiencing the same issue. Any feedback is appreciated.
Thank you for your time, cheers! (:
