It's not just applications on Google play store, but the way most applications ads keep popping up on our smartphone devices on daily basis without have any controls or limitations, it keeps making you be forced to download what you don't really have any needs for.
I have a very bad experience with having to download several applications from Google play store even when I have no need for it because the way these applications keeps popping up and once I mistakenly tap on the application ads, it would automatically start downloading immediately.
I have lost so many data to downloading applications from Google play store which I have no need for. If you ever make a mistake of entering into Google play store, you are definitely going download applications you never wanted to.
