This morning, while logging in to Kickstarter on my tablet, my phone was marked lost/stolen. Upon investigating further (after marking it as found and stopping the loud alarms), I was able to recreate the issue.
It turns out that the advanced authentication SMS I get from Kickstarter triggers the 'lost/stolen' mode on my Android device. The SMS looks innocent, since it just has one sentence containing the one-time code for login to Kickstarter.
I'm on a Galaxy S7 (unlocked, SM-G930U) running Android 6.0.1.
Anyone out there have a similar issue with a remedy? Thanks, in advance.
