My S 5 just started setting off store alarms as I enter and exit walmart and Kroger over the past week. The greeter at Walmart took my phone thru the door (with no merchandise and no one around) and confirmed it is my phone! There are no sensor tags on it or the case (we checked). Is anyone else having this problem? Anyone know a solution? It did an update last weekend, so I don't know if that may be the cause. I have had it since June and this just started hapening!
