I have an old Samsung Galaxy Ace Duos (GT-S6802) running Android Gingerbread, it is a very laggy phone but I still use it to listen to Music. I got to the Gallery app (system app) and there was a video in a folder Titled: ap_video but when I go to the video's details it says "Title: ad_video" and it's not a typo, the video is "ad_video" but the folder is "ap_video". In the video there is a woman Saying:
They say behind every succesful man there is a woman; Hi I'm Sarah Markel and I believe... you just found that woman, because I'm about to stay behind YOU, yes, yes and guide YOU; Until every last one of you is making that kind of money. Do it, do it now and I promise it will be the most important move you've ever done. (Then there is a black screen saying, "Please complete to the next step") END OF VIDEO.
But I really am a man and I don't have anything to do with business and money and stuff she is talking about in the video. I know some videos can go as an ad in a app. But the last app I installed was 'Retro Arch' which is uninstalled and I didn't saw any ads in the app. There was not a long time since I opened my Gallery but last time I saw that folder "ap_video" and that video titled "ad_video".
