Metal detector at Changi Airport

For several years, I have found the security check in Changi Airport to be ridiculous. To avoid the beep as I walked through the metal detector, I remove my key chain, belt, pen, coins and other objets . The detector still beeped, requiring a body frisk.

I did not have to go through this situation in most other airports. Changi Airport seems to be the exception. I have given several feedback, but it went unheeded.

To my great surprise today, the detector did not beep, although I had my pen, belt, coins and key inside my pocket. Has Changi Airport finally acted, after a few years, and changed the sensitivity of the detector? I have to try a few more occasions to be sure.

Perhaps, other travellers can share their experience?
