Fairphone 2: Crazy touch inputs (touchscreen issue) - workaround (for some): increase touch & hold delay

[Heiner]

The buttons are embedded in flexible strips. These strips are fixated to the case on both sides of each button. It isn’t so obvious at first, but you can carefully pull the strips (including the buttons) off those fixating points. And if you’ve done that, you can carefully fixate the strip with the camera button to the power button’s place (if it won’t snap in place easily, use a fingernail or some not too sharp tip of some kind to gently push it in place) and the strip with the power button in the same way to the camera button’s place … and voilà .

To fix the swapped buttons again at the frame doesn’t work with my slim case. It comes off again when I open the case. What can I do not to get lost of the buttons and fix it again at the frame?
The story before: Some month ago I got a warranty slim case and used it since than without problems. But nowadays - meanwhile switched some weeks ago from Open OS to LOS - problems arouse with flickering screens, jumping from app to app, making the phone unusable. I calibrated the proximity sensor, cleaned the screen contacts, but all that didn’t help. So I swapped the on/off button with the camera button and it seems, that it helps.
