I am wondering where the numbers of the fix are coming from, since one of the parameters seems to be out of range:

Code: 
echo $val_cycle > $dev/cycle    # Duration Cycle. Valid range is 0 - 3.
echo $val_nburst > $dev/nburst  # Number of pulses in burst. Valid range is 0 - 15.
echo $val_freq > $dev/freq      # Burst frequency. Valid range is 0 - 3.
echo $val_threshold > $dev/threshold # sensor threshold. Valid range is 0 - 15 (0.12V - 0.87V)
echo $val_filter > $dev/filter  # RFilter. Valid range is 0 - 3.

Taken from the source code for mango (Xperia mini pro).

Edit: interesting: "16 - 31 is a special range for smultron only (SP)" (see here)

Conclusion: this fix might only be for smultron (Xperia mini).

Edit #2: that seems to be correct, since the bug report is for smultron.

I don't know, but according to the documentation one of the values is out of range, except for smultron.

Code: 
val_nburst=26

"Number of pulses in burst. Valid range is 0 - 15"
"16 - 31 is a special range for smultron only (SP)"

Try both sets of numbers if you are having problems

My wife's Xperia Mini is running CM9. The CM9 numbers from the initial post didn't work at all, but the CM10 numbers worked fine. So if you have this problem, do try both. (Back up the file before changing it!)

i have a method to fix this bug on cm9

things we need:
Root explorer

what should we do:

1: open Root explorer and go to the system/etc
2:find hw_config.sh and open it with texteditor
3:in hw_config.sh,find this line:
#proximity sesnor configuration
4:replace next lines with this values...

val_cycle=2
val_nburst=0
val_freq=2
val_threshold=5
val_filter=0

for cm10: (thanks to Steph310)

val_cycle=0
val_nburst=26
val_freq=0

Can anybody fwd this fix to FXP CM 10?

This fix working great for FXP CM10 builds for my Coconut. Can somebody add this to the FXP build itself because everytime you do a Flash you need to again add this fix. It would be good if this comes with core build itself. :laugh:

Works!

Confirm working on xperia Z.
I use a thick tempered glass screen protector and changing the threshold solved the proximity sensor problem!
Thank you very much :)

I used it on my Xperia Mini CM 9.1 with MesaHybridKernel 4.4 and doesn't work. I must use particular permission for the file?
I tried to execute it but the problem persist :confused:
