The sense port is not the only way to break the sensors .... If you look on the internet there are many others who have not heard about of this port and have broken sensors...
It's true, that occurred to me when Porting the Xperia Stock ROM, before the Sense Port even existed.
After a while of testing (and actually getting to the boot animation) I have rebooted at one point into another ROM via multiROM/Multibooting and noticed that my rotation didn't work and then all the sensors.
Back then I searched the web trying to look for a solution or answer but couldn't find anything on it so I returned it via Warranty assuming it was a hardware fault (got it two weeks after).
During these 2 weeks the Sense port was first released and the fix for sensors came just before I got the device back. (Interestingly enough at LG factory they replaced my main PCB of the phone)
I also heard reports of people losing their sensors even after a stock OTA update somehow but can't confirm legitimate.
However don't ask for the ROM, during the two weeks I didn't have the Device I've had scrapped it.
