Bug - Slow unlock when Wifi Sense is turned on.

Since updating to WP8.1, I noticed a significant lag when I unlocking my phone (Lumia Icon), especially after having it idle for a few minutes. It would take about 3-4 seconds from pushing the button to the phone unlocking. I noticed it would only occur when I was connected to Wifi, so figured it was related to that. After tinkering, I noticed the problem does not occur when Wifi Sense is turned off.

I'm not sure if it's a WP8.1 issue, firmware issue, or an issue just with the Icon, but I'm curious if anybody else has experienced this bug. In the meantime I'm just keeping Wifi Sense turned off.

It will likely be a bug with the software if you have any more issue post in this thread:

hai, i've been having the same problem for past one month already, where my nokia lumia 925 always take some time to unlock, roughly 3-5sec. Even when I turned off my wifi sense, the problem is still there. What do you recommend me to do? I really need a solution for this, it's kind of annoying.
