Are you running stock device or openmode?
any tweaks/mods installed?

Tips. Check the alignment of the proximity sensor.

Yeah, it sounds like your proximity sensor either got unplugged or misaligned. If the sensor is telling the phone it is in your pocket, neither tap-to-wake nor the power button would work.

If you replaced the battery, I'm sure you know what you are doing, but this video will show you what you need to be able to check the proximity sensor.

I actually followed the same video to replace the battery, I saw it again in case I missed anything, I connected the proximity sensor cable as in the video, After I connected the sensor cable the device freezes once the device is on.

I had an issue with one of my N9s a week ago.
Tried to unlock it with double tap, upward swipe and power button, but nothing.
It was displaying the Meecast Weather screensaver and time, as usual but I just couldn't get a response from the screen. My 16GB N9 was working fine.
So I plugged it into my PC and set "Diagnostic Mode". I didn't have to touch anything or type anything in, it just unlocked the phone, lit up the screen and since then it's been fine.
But due to the fact Venusingri has dismantled his N9 to replace the battery his problem could be hardware related......probably dislodged something or put something back wrong during the operation.

I actually checked over and over again but still the same problem. If I unplug the sensor cable the device works fine but device will lock but won't unlock and if plug in the sensor cable the device will freeze the movement the device is on.

guys any help with my n9 ?

To me, this makes it pretty clear that something is wrong with your proximity sensor or the connection to it. I don't have any idea if those are hard to come by these days, but I think it sounds like the culprit.

Obviously if could be something wrong with the connection on the motherboard, but hopefully that is not the case.

In past month, I replaced battery, and have same issue. Your proximity cable was broken. I oredered one proximity cable & replace and device working as new.

Hi there. Where did you ordered your N9's proximity sensor from?
I'm looking at this but don't know if it is reliable
