Basically what's in the topic. It's a Nexus 5 phone with the original Android OS (latest version 6.0.1), it's not and it's not locked to any particular carrier. I was never asked to install that app , I wasn't even browsing Google Play Store today, neither from the phone, not my computer that logged in to my Google account. How is it even possible? Who installed that app on my phone without my consent? Frankly I wouldn't even care, but this app is basically taking your phonebook data, so it's kinda creeping me out that it's popped on my phone just like that.
