So I have those pants in which Jolla refuses to stay locked, standard black bigstar jeans. They're most likely chinese and I think they might've been covered in radioactive paint. Simple test: place phone with proximity sensor covered against shirt, no ammount of double tapping wakes it up, against jeans - unlocked every time. If it's not radiation, then what could possibly be tipping of proximity sensor? Edit: hmmm, apparently need more reading on proximity sensors, it's supposed to emit signal and await its return, would that mean my jeans are so well absorbing that it thinks the signal never bounced? goodbye geiger counter I guess ):
