Double tap suddenly stopped working on my N9. Also it doesn't show time anymore on stand by screen. I noticed this while charging my phone. Saw that the screen of my phone has went black. Picked it up, tapped the display for numerous times, nothing. Then woke it up with on/off button.
This is really disturbing, because i'm so used to the double tap function and stand by screen.
definitely prox sensor cable loosen,u drop it hard?I experience that n manage to fix it by opening the fone (t5 torx) n gently reattach prox film cable(double sided tape too)..check out le55ons from ytube..helps u visualize the whole process..hth
Also,
Have you installed a tool such as GConfik? I've noticed that it somewhat breaks the proximity sensor functionality, as it does not detect when the object on top of it is removed.
Installing GConfik prevents the lock screen from showing after the proximity sensor is blocked. It happens to me, and I believe it happened to another user as well with the same issue.
"Notepad can break and destroy your system. Don't install Notepad and remove it as soon as you read this message. Notepad can open text files, and you know most of config files are texts" - your sentence just like that for me
