Phil (Adam Devine) has a major dependency issue - he's addicted to his phone. He has no friends, he has a job writing pop culture "Top 10" lists, and his love life is non-existent. But his Facebook status is about to change. When he is forced to upgrade his phone, the latest model comes with an unexpected feature...Jexi (voiced by Rose Byrne) --- an A.I. life coach, virtual assistant and cheerleader. With her help, Phil begins to get a real life. But as he becomes less dependent on his phone, Jexi's artificial intelligence morphs into a tech nightmare determined to keep Phil all to herself, even if it means ruining his chances of finding success.
