When I switch my phone on the time screen appears normally. When I swipe this to get to the loader a series of full screen ads appears. They advertise Amazons app and come from ads by google. I have to swipe these before I get to the loader. Apart from being annoying, these could delay the use of the phone in an emergency. Is there a way of stopping this ? I appreciate that we must tolerate adverts but I feel this is a step too far. Any help much appreciated.
