I’m trying to take a screenshot on my FP2 slim with newest Fairphone Open OS installed. When I press both the volume-down and power buttons, nothing happens for about five seconds, then the phone reboots.
This can be reproduced every time, and happens also immediately after startup.
I do get random reboots, but most of the time when I have scrolled through a list for some time, stopped to read something and then resume scrolling. I’ve had the same on my HTC Desire before, so I didn’t get suspicious about these, just rolled my eyes a bit.
I see that the reboots happen when pressing the power button for a long time — that explains at least that part — but I wonder why the screenshot function isn’t triggered here if both the power button and volume-down button presses are registered correctly.
