Looks like a few cold joints there. Using a clean hot iron, re-touch any solder joints that are not smooth and shiny.

Also, where the solder has balled up around the pin, it often has not properly wetted the pad. Re-touch those to make sure that the solder has flowed well onto both the pin and the pad.

Now having problem installing the magnet to the frame. How to install it within 1 cm close to the sensor? if > 1cm, the LEDs not blink.

use some sort of spacer, a visit to your local hardware store will probably help you find a few options!
