Google Confirms Pixel 2 XL Wake Up Delays After June Android Security Update
If your Pixel 2 XL seems to have slowed down on wake-up after the June Android Security Update, you are not alone. Yesterday Google confirmed that a bug, which was likely introduced with the update, has caused devices to take 1-3 seconds to wake up after the power button is pressed or the fingerprint scanner is used. They also identified that the issue only impacts Pixel 2 XLs that have had the Ambient Display is disabled in Settings.
The work around to the problem is to turn the Ambient Display setting to Always On until Google can roll out a patch to fix the issue.
