Device takes 2~ seconds to unlock screen

[AC Question]

hello friends!

i just bought a J7 samsung phone (android 5.1 ) , and everything is working fine, except that, when the phone is locked, and i pressed the button to wake up the screen it takes around 2.5 second to show the screen, is that normal in thi phone? if not, is any setting or something i can do to solve this?

Thank you for your help

Welcome to Android Central! Try booting into Safe Mode, which temporarily disables all 3rd party apps. https://support.t-mobile.com/docs/DOC-26249

If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.

So it still happens in Safe Mode? If so, try reinstalling the firmware using Samsung Smart Switch.
