Unlock screen lag

[Members_pBeaKNQ]

Is anyone else experiencing lag when unlocking the phone? I have no security protection. When i press the unlock button it reacts after 2 seconds and then when I swipe up, again, nothing happens for 2 seconds. I'm also experiencing lag with the shutter button on the camera

To ensure that your phone is running optimally, please head to Settings > Battery and device care > Memory > Clean now. This will usually help with any lag you are experiencing 🙂

yeah I had the same issue it was the light sensor, restarting your phone should fix the issue.
