You can bypass the Moto G5 Plus Prime Edition lock screen by tapping an ad (Updated)
June 07, 2025
On-body detectionis a smart lock feature introduced with Android Lollipop that aims to reduce the time a user spends unlocking their device. It uses a smartphone’s accelerometer to detect if the handset is still being carried/used by the person who last unlocked it. This feature was seemingly enabled for the user who was able to bypass the lock screen, so the device’s security and advertising features were working as intended. The user maintains that theydidn’t activate it manually, however.
Twitter user@jaraszskirecently uploaded a video earlier this week (caught earlier today byAndroid Police) that shows how the Moto G5 Plus Prime Exclusive can be bypassed with a rather simple workaround. In the video, the user taps the fingerprint sensor button—which says “not recognized”—then hits the power button, before tapping on the Amazon lock screen ad that pops up to gain full access to the device.
What’s more, this doesn’t appear to be an isolated incident, as a second video has also beenuploadeddisplaying the same problem.
With smartphones being home to so much of our personal information, being able to hypothetically unlock another person’s device in such a simple manner is alarming. But it seems thatnot all userscan recreate this workaround, whileothers saythat it happens to them only if they have already unlocked the device within the last 30 seconds or so.
It’s certainly something that should be investigated, but it might still be too early to say this is a gaping security issue: perhaps it’s related to a rogue bug or something that certain users have (inadvertently) installed/changed. I’ve reached out to Amazon regarding the matter and will update this story when I hear back; let us know in the comments if you’ve experienced this or something similar.
