These shits run adverts which redirect to their site where they display this advert with no way of backing out.
I’ve no idea if the app they link to in the Play Store is legitimate or not. But my tablet does NOT suffer from memory problems, so this company ( based on domain on com-trckr . co ) are basically lying to you. I’d love to report their site as fake from Chrome on my browser on my table but I can’t.. .guess it will have to wait until I get home
