Ever since my 4x HD was new I've noticed a problem, but it's getting so annoying now I finally thought I should do something about it, and I've contacted LG with a view to sending it off for repair:

When I remove the phone from my ear the proximity sensor usually fails to wake the screen back up, meaning I have no controls to end the call with. Occasionally swiping my finger over the sensors at the top of the screen wake it up, but mostly it takes several attempts, and presses of the screen lock button.

SO annoying when you are leaving someone a voicemail and it's still recording, all they hear at the end of the message is the muffled swipe of a finger and me muttering and swearing at the phone as it carries on recording for another 30 seconds or so!!

Anyone else have this issue??

Mine doesn't awake in the end of calls too... but I thought it was normal

We have an option where we can use "Power button" to turn off calls...

I didn't knew that the proximity sensor was suppose to wake up the disply...

Hi Rudeas,
Glad it's not just me!
Where is the option to use the power button to end calls?

Maybe a really daft question, but I presume you haven't put a screen protector on that covers the sensor? Stone of the cheap protectors do and that would stop it working properly.

To test and eventually to calibrate the proximity sensor, you can use hidden menu (dial 3845#*880#) -> Device Test -> All Auto Test Menu Full -> ALC / Proximity Test.
You can even test the "auto brightness mode" (to test also the light sensor) and "enable proximity wakeLock" (to simulate a call).
To test the sensor just put a finger near the sensor.
There is also a "Calibration" feature to calibrate the sensor if needed.

Wow italianquadcore! That is amazing! Firstly I could see by putting my finger over the sensor how poorly it was working. Often it wouldn't notice I had taken my finger away- then I pressed calibrate, and now it notices instantly, every time!!

Thanks loads, I'm assuming it's fixed now!

Italianquadcore is a lifesaver, right?
