TL;DR<\/p>\n
Android 15\u2019s Theft Detection Lock<\/a> has been raising some eyebrows lately. Reports are emerging that the feature frequently activates on its own even though no theft has occurred.<\/p>\n Launched as a part of Google\u2019s broader effort to enhance security with Android 15<\/a>, the Theft Detection Lock uses AI and some other parameters to detect if a phone is forcefully taken from its user. If someone snatches the device and flees \u2014 whether on foot, by bicycle, or in a vehicle \u2014 the system automatically locks the phone. Theft Detection Lock is also triggered when a device goes offline, something thieves commonly do to prevent tracking.<\/p>\n However, users on Reddit<\/a> are reporting that the feature appears to be a bit too eager these days. Several people have described scenarios in which their phones locked unexpectedly, even though the devices were in their possession.<\/p>\n \u201cIt\u2019s happened to me when I ran out of work,\u201d one user shared.<\/p>\n \u201cI was sitting on the bus when the auto theft detect triggered and locked my phone,\u201d another user wrote.<\/p>\n One individual described jogging across the street and being surprised when their phone locked mid-run, only to receive a theft notification moments later. \u201cI was relieved and impressed,\u201d they said, noting that while the system works, it may be a little too sensitive.<\/p>\n Theft Detection Lock primarily relies on a phone’s accelerometer to sense sudden movements.<\/p>\n At Android Authority, we had to simulate multiple theft attempts during early tests<\/a> before the Theft Detection Lock was activated on our test device. This suggests Google may have increased the sensitivity of the detection algorithm since launch.<\/p>\n Google previously told us that Theft Detection Lock primarily relies on a phone\u2019s accelerometer to sense sudden movements or changes in direction, which could explain the false triggers during activities like running or commuting.<\/p>\n Despite the glitches, most users don\u2019t seem overly frustrated. Still, unexpected lockouts don\u2019t look great, and Google should work on refining the feature to make it more reliable.<\/p>\n
