Go into location settings click the 3 dots and turn off wifi scanning. This should fix it
And just out of curiosity were you using Zen decision when you took a screenshot of app drawer
I'm curious because since you said you were using, it doesn't actually look like it's working because there is only one core online in the screenshot of your app drawer. All the cores should be online all the time which could be your having slow downs
Well i'm using 5.1.1 so i have disabled the wi fi scanning in wi fi settings from day one. This screenshot is the one immediately after the reboot. For appx 10 mins, only one core was active. after that, the hotplug started to work properly. Is it a Zen hotplug bug or is something else preventing the cores from kicking in. And i have no idea why the gpu min speed was set to 0 Mhz. That's totally un-necessary. Without a running gpu, UI would suffer greatly.
