Recently, users have reported that after updating the Android 8.1 Oreo a sliding screen bug appeared under the lock screen, a problem that appears to affect Google’s pixel and Nexus devices, and now Google says it understands the problem and is investigating why.
Android 8.1 Oreo Unlocks the pixel Visual core core of the Pixel 2 handset, which will greatly enhance the Pixel 2 ‘s camera function. Unfortunately, this update will also cause trouble to users. According to Google product forum and Reddit forum users feedback, some pixel and nexus user found that they occasionally in the sliding screen to unlock the request to enter a PIN verification code. There are also users that they can not be locked in the screen when the message to clear the banner, can not drop the notification menu, and so on, it is somewhat strange.
Whether this issue is a continuation of the November slide-screen bug, Google does not seem to have completely fixed the problem. A netizen indicates that restarting the device in recovery mode can solve the problem.
