[SOLUTION] Temporary lock button delay & Double tap to wake fix!

My Yu Yuphoria have this delay lock bug. Well I have found a solution, I don't guarantee that it will work for you but you can give it a try.

You only need to download a 3rd party lockscreen app like CM LOCKER, AcDisply, etc and disable the default lockscreen.

I'm using AcDisplay, it works perfectly, but I still face delay but after 1-2days of usage then only you need to reboot your device.

Hope it helps you too, if you are facing the same problem.
