recently my Note 4 has been, at the oddest moments, splashing up a screen to warn me of danger and upgrade my system. I know its fake, the grammar is horrendous ! I cant find or figure out why its happening. also along the same theme, a screen will pop up with a siren tone advising me im a "winner". I have not allowed them to go any further but they are really annoying and I know they shouldn't be there. I did download a virus app off google play but it didn't see this issue as it has continued so I uninstalled that also.
any help would be much appreciated.
