Info I wrote above happens "after" swiping lock screen and entering my password.
Also please note this auto tab opening only happens "once a day" which is the 1st time I turn on the tablet in the day
no matter how many times I put the tablet either "off" or to "sleep"
This morning my battery was almost drained even though it was fully charged last night, it was on sleep overnight.
If I'm reading this correct in my running apps I have the following:
Settings/ Outlook/ Opera/ Opera/ Daily Mail/ com.intel.widi.uiba/ Google Services/ Maps/ wuaki.tv/ My Tesco/ gboard
and these 3 were running and I have now removed Superhero/ Kids Police Station/ Compass
