After updating my Lumia 720 to 8.1 I have noticed that my phone takes some time to wake up. There
is a 5 second delay when I click the Power/ Lock button to when my home screen displays. I performed a reset on my phone and the problem still persists. I have also done a full reset clean one with Lumia Software Recovery Tool.
Even on cyan version without developer preview the problem still persist. I have removed memory card class 8 but still persist and move apps to sd card, in other word i have done all the possibilities. My hardware was fully check and
its a software bug. Please help me.
We have moved our support forum for OS Consumer Support,
i.e. almost any support of the Preview for Developer release that is not related to developing an application, to the Microsoft Community website here: http://answers.microsoft.com/en-us/winphone/forum/wpdp
