I thought it would be useful if people would report oneui 3.1 bugs they came across and/or a solution.
I don’t know if this happened to everyone: my bug – while in do not disturb mode/contacts allowed, the ringer would NOT pop up on allowed incoming calls. One would have to go into notifications to answer the call. This only happened after 3.1.
The solution:under the do not disturb tab in settings, under ‘exceptions’ one has to manually allow (via slider) both the ‘call’ and ‘phone’ apps.
