Hiya at Google's Play Store does not have an UNINSTALL option, so if you DOWNLOAD Hiya caller I. D.,,, You may be Stuck with it,,, FOREVER!! and Google troubleshooting guy says "Google is OK with that." Thus, PLAY STORE is Not a Safe Place.

Most apps have an UNINSTALL option.
Hiya does not have one,  or an icon to slide to UNINSTALL, and is not listed with all your other "smartphone" apps.

And Google is fine with this.
Their representative said "Some people may really like Hiya and never want to uninstall it."
And "we are not responsible for what we offer on Google Play Store."

YIKES!!

NO MINIMUM STANDARDS.
BEWARE of Google Play Store!!
