For example, Logitech M535 works fine: https://www.logitech.com/de-de/product/bluetooth-mouse-m535?crid=7

@flohack Thanks for your message. I updated my OPO to OTA7 and there was no problem with WLAN.

@Flohack @rbarclay : So far I haven't received the update to OTA-7 for my OPO yet, hopefully it will come today. Do you advise to update the OPO to OTA-7 or shall I wait until this bug is resolved?

@flohack Thanks for the info on the (non)progress talking to OWS. It is really weird how OWS handles community activities.

In the meanwhile Aaron has continuously updated the Signal app and it works well, so far: https://open.uappexplorer.com/app/textsecure.nanuc

@dobey Thanks for your reply. How can I test it whether there is a bug related to the proximity sensor or touch digitizer?

Intuitively, the touch digitizer does not seem to be disabled.

I would like to report a small design problem in the UBPorts UI, which is simple, but can be quite annoying:
It happens to me quite frequently, that - while talking to someone on phone - my ear switches on the flight mode in UBPorts. Of course, the connection immediately terminates and it takes some time until I can call the other person again (after disabling the flight mode again).
Apparently my ear "navigates" through the top menu bar of my smartphone while talking on phone and somehow activates the flight mode. Does anyone else also experience this issue?

I have had the issue already with my BQ 4.5 and also experience it with my OPO. It also not a new issue, but it occurred already in the old Ubuntu Touch.
