It's happened when I closed all tabs in chrome. It has happened after uninstalling an app. It's happened after selecting to greenify google play services - and wiped all the greenify settings. It's happened at, as far as I can tell, random times and circumstances.
It is probably kernel related but this is a new tablet for me and I'm not too familiar with any custom roms or kernels on this device. Currently running xKat v4 with the included kernel.
Anyone else experiencing this? Anyone have a fix recommendation or suggestions?
