For me it seems, that the 1.1.1.27 has an sideeffekt to the proxymity sensor.
I always have the settings 'Display off when active' and 'Proximity' checked.
So normal use case for me at night:
- put the jolla on the table with toholed on top
- put something on the proximity sensor to switch the oled off(to not lighten the room)

The day use case for me is of course the oled activated (during meetings for example).

Actually the proximity sensor doesn't work as reliable as before.

After systemctl restart harbour-toholed.service i switch the main display off.
Then i put my finger on the proximity sensor and off.

Before the sailfishos update i'm sure you could activate the oled by the proximity sensor like a switch.
Now sometimes i have longer response times than before until the point where it doesn't act anymore .

By restarting the service i can again use it for some times.
So generally i suppose the sensor is ok.

Anyone can state that behaviour or am i the only one having this problem ?

(journalctl - f out of the box reports nothing about the proximity sensor state)
