AVG free now requires access to my video camera and microphone. It did not before. So I looked into it. Guess what? It does use the cam. It does take pictures. Format your phone and wonder why all text messages, pictures, phone log, address book, ect. came back? They upload all personal info to the cloud the second you signed into Google play! The second you register your phone you pretty much have a log of everything you do kept online. (So you can recover it). That's why you sign in to Google. Google apps are a lot like Facebook. If they are giving you free apps, guess what? YOU are the product. Google/Facebook/twitter. This is common news, they are super rich because they openly record anything you do on their server. Call and ask they will tell you. Don't worry though. Even though they collect all the information, and sell it to anyone with $. They have a policy, don't be evil. That's how they self regulate their data mining practices, with a slogan don't be evil. I have done some looking through my cashe, micro sd, and auto cloud storage. Apple is pretty good about not allowing so many apps that are flat out viruses. AT&T is just flat out horrible with the bundled software. I disabled as much as I could but still have some battery drainers that I cannot get rid of. And then they try to update all the time (programs I did not want). I have a quad core and it is amazing how much is going in the background when you think you are just calling someone. Oh well, in my town they have video cameras mounted to the corner of every street and intersection. Guess I should just get used to privacy being a thing of the past.
I love Android OS, just don't fool yourself into thinking you have privacy with anything from Google. They are a data mining company by definition. Yes they do and will collect and sell your data.
Sorry, ranting. Take care.
