One in particular ad is for me to install the "Ibgotta"(sp???)coupon app. I'm not in ANY websites or apps, I clear my cache &/or wipe my cache partion, reboot & the ad/PlayStore pops up with this install?? My phone has also been powering down after uninstalling apps? Any help, much appreciated. You can also view my devices errors on either YouTube or Google+...just seach for "Scorpio2177".
